306 JavaScript For Automation [English].srt

1
00:00:12,082 --> 00:00:14,401
well come welcome the Friday

2
00:00:15,139 --> 00:00:16,900
thanks for being here

3
00:00:16,009 --> 00:00:19,038
my name is south to go in I am the
product manager for automation

4
00:00:20,019 --> 00:00:22,081
technologies that Apple incorporated

5
00:00:22,081 --> 00:00:26,116
and the secession 306 this is a big day

6
00:00:27,016 --> 00:00:32,072
we get to welcome JavaScript to the
family of scripting languages on OS 10

7
00:00:32,072 --> 00:00:39,072
we've been waiting a long time for this
and I know our customers have to and

8
00:00:41,008 --> 00:00:42,012
we're really thrilled about it

9
00:00:42,048 --> 00:00:46,767
and before I get into the details have
the language and how it works

10
00:00:47,199 --> 00:00:50,294
I like to take a moment to reflect on
the state of automation

11
00:00:51,149 --> 00:00:54,190
beginning with Mavericks

12
00:00:54,019 --> 00:00:57,091
now in maverick's reintroduced

13
00:00:57,091 --> 00:01:00,168
a host of new features some very
powerful things beginning with

14
00:01:01,068 --> 00:01:02,075
notification support

15
00:01:03,038 --> 00:01:07,060
in both the scripting language in in
Automator as well so it became very

16
00:01:07,006 --> 00:01:11,099
easy to use notifications and set a
posting dialogues in your automation

17
00:01:12,053 --> 00:01:13,059
routines

18
00:01:13,059 --> 00:01:18,075
we also introduced code signing ability
in our editor applications both in

19
00:01:18,075 --> 00:01:19,161
Automator in the script editor

20
00:01:20,061 --> 00:01:23,160
which is great because then you could
sign and deliver

21
00:01:24,006 --> 00:01:28,009
automation solutions to your customers
friends and coworkers

22
00:01:28,063 --> 00:01:33,552
we also introduced a new construct in
AppleScript called the use statement

23
00:01:34,119 --> 00:01:38,140
the racks I can importer to import
functionality from

24
00:01:38,014 --> 00:01:42,097
applications and frameworks and %uh
scripting additions

25
00:01:42,097 --> 00:01:45,125
and allow them to be used in your
scripts

26
00:01:46,025 --> 00:01:50,106
and by doing this we also made it
possible to have script

27
00:01:51,006 --> 00:01:55,014
library that we introduced and script
library for scripts that you create

28
00:01:55,086 --> 00:01:55,185
yourself

29
00:01:56,085 --> 00:02:00,088
that contain your favorite some routines
are handlers

30
00:02:00,088 --> 00:02:04,717
and you can call in lo these libraries
from scripts anywhere in the operating

31
00:02:05,509 --> 00:02:06,210
system

32
00:02:06,021 --> 00:02:09,114
they can also take advantage of
AppleScript objective-c

33
00:02:10,014 --> 00:02:13,040
and any the cocoa calls that you want to
use

34
00:02:13,004 --> 00:02:17,005
so they're very powerful very useful
they be introduced

35
00:02:17,005 --> 00:02:20,334
and then finally we had a new feature

36
00:02:20,829 --> 00:02:24,885
that worked on english-only systems but
we thought it was so interesting that we

37
00:02:25,389 --> 00:02:28,820
introduced it it was called speaker
bulwark locks

38
00:02:28,082 --> 00:02:31,561
and allowed you to take your Automator
workflow

39
00:02:32,299 --> 00:02:35,650
and save it as a speaker bull item

40
00:02:35,065 --> 00:02:39,066
in the dictation architecture so you
could say a command in would run your

41
00:02:39,075 --> 00:02:39,744
workflow

42
00:02:40,419 --> 00:02:44,590
and so maverick's is a very productive
release force we're very excited about

43
00:02:44,059 --> 00:02:44,488
it

44
00:02:45,019 --> 00:02:50,047
but we're also excited about what we've
done in Yosemite and how it builds upon

45
00:02:50,299 --> 00:02:51,970
the groundwork relayed

46
00:02:51,097 --> 00:02:54,103
in Mavericks last part of this

47
00:02:55,003 --> 00:02:58,022
evolutionary process we integrated

48
00:02:58,022 --> 00:03:02,109
code signing with workflow files so not
only app lets but now your workflow

49
00:03:03,009 --> 00:03:05,188
files can be code side as well

50
00:03:05,269 --> 00:03:10,160
and because have changes that we
implemented in the app script language

51
00:03:10,016 --> 00:03:11,017
for supporting

52
00:03:11,026 --> 00:03:14,185
optional parameters and subroutines and
handlers

53
00:03:14,419 --> 00:03:20,620
wearin able to upgrade the scripting
library support so that you can now have

54
00:03:20,062 --> 00:03:21,271
your favorite calls

55
00:03:21,829 --> 00:03:26,680
have optional premonition users as well
very good improvement there

56
00:03:26,068 --> 00:03:30,079
and listening to customer requests
they're being

57
00:03:30,079 --> 00:03:34,868
for years and years requesting some way
to indicate a progress

58
00:03:35,579 --> 00:03:39,584
method for their automation routines we
now have

59
00:03:40,079 --> 00:03:43,220
built in script progress indicators

60
00:03:43,022 --> 00:03:46,079
so by calling simple properties

61
00:03:46,079 --> 00:03:50,088
you can have your scripts display a
progress

62
00:03:50,088 --> 00:03:53,197
indicator as a circle or even as

63
00:03:53,989 --> 00:03:58,993
a progress bar in a floating window and
all this is done for you automatically

64
00:03:59,389 --> 00:04:02,880
all you have to do is Sep properties
within your scripts

65
00:04:02,088 --> 00:04:06,627
so I think our customers are gonna
really enjoy that particular feature

66
00:04:07,419 --> 00:04:12,450
and we took the idea of spiegel were
close and we've advanced it now

67
00:04:12,729 --> 00:04:17,060
because %uh the new dictation
architecture in Yosemite that works with

68
00:04:17,006 --> 00:04:17,495
all

69
00:04:17,549 --> 00:04:21,060
languages we now have a new template
item

70
00:04:21,006 --> 00:04:24,115
in Automator for creating a dictation

71
00:04:24,169 --> 00:04:29,630
command so you create your workflow you
save it it's a than to the dictation

72
00:04:29,063 --> 00:04:30,071
architecture

73
00:04:30,071 --> 00:04:34,096
and when you're in the process of
dictating or just sitting at the machine

74
00:04:34,096 --> 00:04:37,177
you can't say the name your command
anymore execute

75
00:04:38,077 --> 00:04:42,078
very interesting very powerful I know
you can have a lot of fun exploring

76
00:04:42,078 --> 00:04:46,143
that so that's just a quick overview up
where we've been

77
00:04:47,043 --> 00:04:51,182
but something that's been on our minds
for a long time that we're happy

78
00:04:51,569 --> 00:04:57,050
and very pleased to have here today is
JavaScript for automation

79
00:04:57,005 --> 00:05:00,008
now those have you there are

80
00:05:00,008 --> 00:05:04,317
premiere with JavaScript from the
web-based community

81
00:05:04,389 --> 00:05:07,650
this is not the JavaScript for writing a
DOM

82
00:05:07,065 --> 00:05:10,161
that uses CSS and HTML 5 to create a web
app

83
00:05:11,061 --> 00:05:15,270
we're talking about extending the
JavaScript cord language

84
00:05:15,819 --> 00:05:18,838
to integrate with the open scripting
architecture

85
00:05:19,009 --> 00:05:23,250
and by doing this you now gain the
ability to pull

86
00:05:23,025 --> 00:05:27,033
all those levers inside the scriptable
caps on your operating system

87
00:05:28,005 --> 00:05:32,524
to perform the kinda repetitive for
interesting or complex tasks

88
00:05:32,569 --> 00:05:37,330
that you do every day and now this power
it's available to you

89
00:05:37,033 --> 00:05:40,062
through JavaScript now many of you that
right

90
00:05:40,062 --> 00:05:43,981
JavaScript professionally or as your
focus

91
00:05:44,539 --> 00:05:47,870
you use to using editors like God BB
added

92
00:05:47,087 --> 00:05:50,108
sublime tax were web storm

93
00:05:51,008 --> 00:05:54,127
TextMate things like that up

94
00:05:54,199 --> 00:05:58,870
initially as you adapt to JavaScript raw
to Mason

95
00:05:58,087 --> 00:06:02,386
you write your for scripts in the script
editor application

96
00:06:03,169 --> 00:06:06,500
and I'm gonna give you just a short
overview up

97
00:06:06,005 --> 00:06:09,354
this application it's interfacing
preferences

98
00:06:09,849 --> 00:06:13,800
so that you understand what's happening
as David presents

99
00:06:13,008 --> 00:06:16,367
JavaScript for you so let me take a look
at

100
00:06:17,159 --> 00:06:21,060
the script editor application so when
you open

101
00:06:21,006 --> 00:06:26,071
the script editor application get this
very simple interface is a script window

102
00:06:26,071 --> 00:06:29,810
and he has a simple but very powerful
design to it

103
00:06:30,449 --> 00:06:34,477
beginning with the little slider that
separates the two main pains up the

104
00:06:34,729 --> 00:06:35,560
window

105
00:06:35,056 --> 00:06:39,058
the script pain where you enter the code
for your script

106
00:06:39,058 --> 00:06:42,099
and the bottom pane contains in a vet
law

107
00:06:42,099 --> 00:06:46,588
so ass the script is executing you'll
see the events listed there with the

108
00:06:47,479 --> 00:06:49,520
results coming in from the Abetz

109
00:06:49,889 --> 00:06:53,973
and this is all I've logged happens as
the script is executed

110
00:06:54,729 --> 00:06:59,530
at the top there are some simple
controls for basically compiling the

111
00:06:59,053 --> 00:07:02,022
script to make sure your syntax is
correct

112
00:07:02,499 --> 00:07:06,560
and there's also control for running or
stopping your script

113
00:07:06,056 --> 00:07:10,143
now there at the bottom here is a
language controls so make sure if you're

114
00:07:11,043 --> 00:07:12,552
writing JavaScript

115
00:07:12,939 --> 00:07:18,941
that this pop-up menu is set for the
JavaScript language

116
00:07:19,139 --> 00:07:24,176
and that's basically the interface in
the way that it works is

117
00:07:24,509 --> 00:07:27,518
you enter your script code

118
00:07:27,599 --> 00:07:33,662
into the top area then you click the Run
button

119
00:07:34,229 --> 00:07:38,251
an acid execute you can see that there's
a progress indicator here on the right

120
00:07:38,449 --> 00:07:43,464
showing the progress at the script and
you can watch the event log go by

121
00:07:43,599 --> 00:07:48,608
now this simple script that exported
open keno documents to movies

122
00:07:48,689 --> 00:07:52,620
you can see the results of it and how
was logged in everything indicated in

123
00:07:52,062 --> 00:07:54,541
the final result that the script at the
bottom

124
00:07:55,099 --> 00:07:59,134
so this is the interface that you have
when you're executing scripts in is

125
00:07:59,449 --> 00:08:00,080
David

126
00:08:00,008 --> 00:08:04,157
shows you the examples this is what
you're going to see

127
00:08:04,229 --> 00:08:07,245
there's some other important preferences
you should be aware of and let me just

128
00:08:07,389 --> 00:08:09,860
quickly show you those to you

129
00:08:09,086 --> 00:08:12,785
so in the Preferences menu

130
00:08:13,559 --> 00:08:17,626
from the application menu in the General
Settings paying

131
00:08:18,229 --> 00:08:22,312
there is a default language pop-up if
you going to be using javascript is your

132
00:08:23,059 --> 00:08:25,085
primary language for scripting

133
00:08:25,319 --> 00:08:28,331
you wanna make sure that you change this
value

134
00:08:28,439 --> 00:08:32,120
to JavaScript now this is JavaScript 100

135
00:08:32,012 --> 00:08:35,871
this is JavaScript for automation 10 it
is not

136
00:08:35,979 --> 00:08:41,330
JavaScript what now we use the current
JavaScript court languages the bases

137
00:08:41,033 --> 00:08:44,037
so don't be freaked out when you see 10
their

138
00:08:44,073 --> 00:08:47,100
also make sure that you check

139
00:08:48,000 --> 00:08:51,339
the show's script menu and menu bar
option

140
00:08:51,339 --> 00:08:55,540
and what this will do is activate the
system wide script menu at the top right

141
00:08:55,054 --> 00:08:56,403
up your menu bar

142
00:08:56,889 --> 00:09:01,190
and from this script menu you can host
your favorite scripts

143
00:09:01,019 --> 00:09:05,023
and you can make them available
contextually within certain applications

144
00:09:05,023 --> 00:09:07,037
so if you write scripts for the Finder

145
00:09:07,037 --> 00:09:10,105
they can only appear the finders there
are few write scripts four pages

146
00:09:11,005 --> 00:09:14,030
the only pier 1 pages so there it's up
to you

147
00:09:14,003 --> 00:09:17,072
the script menu run shell scripts
AppleScript applications workflows

148
00:09:17,099 --> 00:09:19,100
JavaScript

149
00:09:20,000 --> 00:09:23,339
any kind scripting language supported by
the operating system

150
00:09:23,339 --> 00:09:27,310
can run from the script min so you'll be
taking advantage of that

151
00:09:27,031 --> 00:09:32,116
in addition if you want to set certain
coloring for you the code that you use

152
00:09:33,016 --> 00:09:37,021
this formatting pain is where you'll do
that you can choose fonts font size and

153
00:09:37,066 --> 00:09:37,795
coloring

154
00:09:38,389 --> 00:09:43,300
to apply to fit comfortably with what
your use too

155
00:09:43,003 --> 00:09:46,592
next I like to look at dictionaries

156
00:09:46,889 --> 00:09:49,952
now in the operating system every
scriptable

157
00:09:50,519 --> 00:09:53,582
application carries internally within
its bundle

158
00:09:54,149 --> 00:09:58,670
a complete dictionary of all the term
said it understands

159
00:09:58,067 --> 00:10:02,079
it will list all the class sense at all
the methods in the commands in the

160
00:10:02,079 --> 00:10:04,068
properties and elements

161
00:10:04,779 --> 00:10:09,820
that is for mayor with so this is where
you will go to learn about how to

162
00:10:09,082 --> 00:10:11,163
control a particular application

163
00:10:12,063 --> 00:10:15,122
and what you do is you choose Open
dictionary from the File menu

164
00:10:16,022 --> 00:10:19,381
and in the forthcoming dialog choose an
application

165
00:10:19,579 --> 00:10:23,623
when you do that York see a script
viewer window like this one for the

166
00:10:24,019 --> 00:10:24,800
keynote

167
00:10:24,008 --> 00:10:27,014
dictionary and this is

168
00:10:27,086 --> 00:10:31,150
what you see when you I'll look at an
application scripting dictionary and

169
00:10:32,005 --> 00:10:36,154
this is what you will do to navigate
that dictionary

170
00:10:36,649 --> 00:10:41,500
at the top is a language button so this
dictionary fewer functions

171
00:10:41,005 --> 00:10:44,016
for all the scripting languages we
support so

172
00:10:44,061 --> 00:10:47,790
it supports JavaScript AppleScript or
objective c-

173
00:10:48,339 --> 00:10:51,375
and you can change the mode for viewing
the content

174
00:10:51,699 --> 00:10:54,790
right from this menu now

175
00:10:54,079 --> 00:10:59,048
at the top part love this window the top
pain in this window is the model viewer

176
00:10:59,759 --> 00:11:01,811
in this is where you see how the objects

177
00:11:02,279 --> 00:11:06,730
in the application scripting model are
reflected

178
00:11:06,073 --> 00:11:10,135
on the left hand side typically a
scripting dictionary

179
00:11:11,035 --> 00:11:16,066
is grouped into sweets and the suites
are usually grouped by functionality you

180
00:11:16,066 --> 00:11:17,110
buy what they do

181
00:11:18,001 --> 00:11:22,050
in this particular example you'll see
that there's multiple sweet

182
00:11:22,149 --> 00:11:26,157
their suites for I work because keynote
is part of the I work family affair

183
00:11:26,949 --> 00:11:28,550
plications

184
00:11:28,055 --> 00:11:32,092
the I work sweets upcoming objects in
common commands

185
00:11:32,092 --> 00:11:35,881
are included there and then keynote has
its own sweet

186
00:11:36,709 --> 00:11:40,721
are things that are particular for the
keynote application

187
00:11:40,829 --> 00:11:45,380
and then once a sweet is selected you'll
see in the next column

188
00:11:45,038 --> 00:11:50,987
the methods and the classes that belong
to that particular sweet so here we have

189
00:11:51,329 --> 00:11:57,050
commands like export we would export a
project presentation EC classes like

190
00:11:57,005 --> 00:11:58,032
document

191
00:11:58,032 --> 00:12:01,101
and then when you select the class
you'll see he

192
00:12:01,389 --> 00:12:04,670
elements X that belong to that class

193
00:12:04,067 --> 00:12:07,149
in the right hand column and also the
properties

194
00:12:08,049 --> 00:12:11,085
I love that particular class in here you
see the properties

195
00:12:11,085 --> 00:12:14,086
I love a keynote document

196
00:12:14,086 --> 00:12:17,565
now for further information in detail
about these

197
00:12:18,339 --> 00:12:21,420
in the bottom half for the Windows the
dictionary viewer

198
00:12:22,149 --> 00:12:26,500
and the dictionary viewer contains the
definitions for all those particular

199
00:12:26,005 --> 00:12:27,018
elements

200
00:12:27,063 --> 00:12:30,069
so when you want to know about why
hideaway script the Finder hideaway

201
00:12:31,023 --> 00:12:32,492
script numbers

202
00:12:32,699 --> 00:12:36,380
how do I skip keynote how do I script
aperture

203
00:12:36,038 --> 00:12:39,131
you open a dictionary and this is where
you learn and explore

204
00:12:40,031 --> 00:12:43,550
to find out how to control those
applications

205
00:12:43,829 --> 00:12:49,050
so that's the scripting dictionary and
that's the script editor application

206
00:12:49,005 --> 00:12:53,794
so let me get out of the way and bring
up David sign bird

207
00:12:53,839 --> 00:12:56,895
whose the newest member of our team to
show you

208
00:12:57,399 --> 00:13:02,240
JavaScript rodham Asian enjoy this

209
00:13:02,024 --> 00:13:05,085
thank you sell hello everyone thank you
for being here

210
00:13:05,085 --> 00:13:09,087
I it's a great honor I'm really excited
to be showing this awesome new feature

211
00:13:09,087 --> 00:13:13,106
OS 10 yosemite JavaScript for automation

212
00:13:14,006 --> 00:13:17,093
so today's talk will cover what
JavaScript for automation is

213
00:13:17,093 --> 00:13:20,188
and how it works how you can use
JavaScript rodham Asian

214
00:13:21,088 --> 00:13:25,047
from basic to more advanced techniques
and finally we'll talk about where you

215
00:13:25,839 --> 00:13:28,937
can use JavaScript rodham Asian

216
00:13:29,819 --> 00:13:32,857
to talk about what JavaScript
proclamation is

217
00:13:33,199 --> 00:13:36,286
let's take a look at the underlying
pieces

218
00:13:37,069 --> 00:13:40,114
automation allows you to accomplish
tasks on your Mac

219
00:13:40,519 --> 00:13:45,526
automatically from simple tasks such as
changing the name to 100 files

220
00:13:45,589 --> 00:13:48,633
all at once to more complex tasks

221
00:13:49,029 --> 00:13:54,600
such as sending personalized directions
to guests before party you're having

222
00:13:54,006 --> 00:13:58,101
I'd like to demonstrate the power
automation to you now

223
00:13:59,055 --> 00:14:02,704
so I were cracking widgets were company
that makes widgets

224
00:14:03,199 --> 00:14:06,930
as you might expect we have three main
clients Japan

225
00:14:06,093 --> 00:14:09,179
USA and across Europe I'm here i've a
chart detailing

226
00:14:10,079 --> 00:14:13,080
summer widgets prices in the region's
they go to

227
00:14:13,008 --> 00:14:16,917
and in particular currency and so on and
now I have

228
00:14:17,709 --> 00:14:21,000
4 upcoming presentations first

229
00:14:21,000 --> 00:14:24,067
I have to give a presentation to the
president of the company about all the

230
00:14:24,067 --> 00:14:24,716
regions

231
00:14:25,319 --> 00:14:29,100
that we work with all other individual
prices currencies and so on

232
00:14:29,001 --> 00:14:32,063
and I have to give presentations to each
those regions

233
00:14:32,072 --> 00:14:36,099
only detailing the particular
information that pertains to that region

234
00:14:36,099 --> 00:14:39,166
so now I'm thinking okay for keynote I
have to make

235
00:14:40,066 --> 00:14:43,104
what start with the first I have all my
data here

236
00:14:44,004 --> 00:14:48,353
format as I wanted I have some images
that I can use related to this data

237
00:14:48,389 --> 00:14:51,440
I write a script that does this for me

238
00:14:51,899 --> 00:14:55,810
well I've done just that so here I have
a script

239
00:14:55,081 --> 00:14:58,084
don't worry about understanding all a
bit at the moment but the dumpster Prada

240
00:14:59,011 --> 00:15:00,072
mation script that uses

241
00:15:00,072 --> 00:15:05,074
this numbers document and produces a
full slide deck for me in keno

242
00:15:05,074 --> 00:15:09,143
so if I run this here we see our slides
are being created for us

243
00:15:10,043 --> 00:15:14,192
with the information that we got from
that data

244
00:15:14,579 --> 00:15:17,654
and now we have an entire slide deck
ready for my president to see

245
00:15:18,329 --> 00:15:21,610
detailing all OVR widgets their prices
per region

246
00:15:21,061 --> 00:15:24,122
currency and so on is perfect okay

247
00:15:25,022 --> 00:15:29,761
some Cup list one completely
automatically I've three more to do

248
00:15:29,959 --> 00:15:33,430
and each of those are going to be pretty
much the exact same

249
00:15:33,043 --> 00:15:36,074
same number of slides same images same
information

250
00:15:36,074 --> 00:15:39,118
changed per region particular currency
and so on

251
00:15:40,018 --> 00:15:44,050
and in fact all the information is
already in this presentation I have here

252
00:15:44,005 --> 00:15:48,013
I just need to slim it down for each
version sorrow myself helper script

253
00:15:49,003 --> 00:15:52,592
a menu that multiple times so I put my
script menu

254
00:15:52,889 --> 00:15:56,908
and what this does is it let me say
where my presenting today

255
00:15:57,079 --> 00:16:00,430
well today many presenting in Japan so I
guess

256
00:16:00,043 --> 00:16:03,104
slimmed-down Mikey now the few slides
that are important

257
00:16:04,004 --> 00:16:08,018
but presentation mode and unable to go
hello everyone thank you for being here

258
00:16:08,018 --> 00:16:11,277
let's talk about prices it's been a real
pleasure have a good day

259
00:16:11,439 --> 00:16:14,800
now okay right now

260
00:16:14,008 --> 00:16:17,027
I me begin the presentation the USA

261
00:16:17,819 --> 00:16:21,490
okay I don't wanna make another slide
tackle together I'm going to use my nice

262
00:16:21,049 --> 00:16:21,141
little helper here

263
00:16:22,041 --> 00:16:25,135
USA hello everybody thank you for being
here let's talk some dollars it's been a

264
00:16:26,035 --> 00:16:28,084
real pleasure have a nice day

265
00:16:28,399 --> 00:16:32,610
beautiful bed and higher entire
automated will process

266
00:16:32,061 --> 00:16:35,137
was automated for me we just a couple
little script that I wrote

267
00:16:36,037 --> 00:16:39,696
that made my life easier got my work
done faster

268
00:16:40,029 --> 00:16:47,029
and that is the PowerVault nation

269
00:16:49,022 --> 00:16:52,081
those demos were made possible by
scripting applications

270
00:16:52,081 --> 00:16:55,137
and applications that are built using
cocoa automatically have a certain level

271
00:16:56,037 --> 00:16:57,306
the script ability

272
00:16:57,639 --> 00:17:01,050
such as being able to be told to open or
to print

273
00:17:01,005 --> 00:17:05,005
and a wide variety of applications have
fully embraced script ability

274
00:17:05,005 --> 00:17:08,100
detailing the object model at the
application and offering rich sweet the

275
00:17:09,000 --> 00:17:14,000
functionality beyond the basics

276
00:17:14,000 --> 00:17:18,086
Apple events underlying communication
mechanism behind application scripting

277
00:17:18,086 --> 00:17:22,133
they provide access to the scriptable
pieces and parts of an application

278
00:17:23,033 --> 00:17:26,124
that are defined an application
scripting dictionary cell showed

279
00:17:27,024 --> 00:17:30,056
detailing what objects can be interacted
with and how

280
00:17:30,056 --> 00:17:34,077
so when the script an application and
whatever language you may

281
00:17:34,077 --> 00:17:37,175
it scripting dictionary is red an Apple
event for use to communicate with the

282
00:17:38,075 --> 00:17:39,083
application

283
00:17:40,055 --> 00:17:44,069
let's take a look at an example of an
object model

284
00:17:44,069 --> 00:17:47,132
there we have mail but as an application
object

285
00:17:48,032 --> 00:17:51,040
with an inbox property with the messages

286
00:17:51,004 --> 00:17:55,012
elementary with each element
individually accessible

287
00:17:55,048 --> 00:17:58,085
so for example we can pinpoint the
second messenger the

288
00:17:58,085 --> 00:18:01,093
in box on the application male as an
object specifier

289
00:18:02,065 --> 00:18:08,078
or a reference to that particular object
in that particular application

290
00:18:08,078 --> 00:18:11,130
this is great we look really closely at
the things behind automation

291
00:18:12,003 --> 00:18:15,090
an application scripting now let's talk
about JavaScript

292
00:18:16,017 --> 00:18:19,076
have a powerful automation was brought
to it

293
00:18:19,076 --> 00:18:22,151
JavaScript is a scripting language with
C like syntax

294
00:18:23,051 --> 00:18:26,056
and objects a prototype based
inheritance its most well known in a

295
00:18:27,001 --> 00:18:27,079
browser

296
00:18:27,079 --> 00:18:30,173
being in the scripting language image
team of five but it's also become quite

297
00:18:31,073 --> 00:18:33,076
popular as a server-side scripting
language

298
00:18:34,003 --> 00:18:37,051
evidenced by node.js JavaScript

299
00:18:37,051 --> 00:18:41,062
analyst 10 is powered by JavaScript core
the engine used by WebKit

300
00:18:41,062 --> 00:18:45,079
and so far JavaScript for automation

301
00:18:45,079 --> 00:18:50,094
is built on JavaScript core using the
modern JavaScript environment

302
00:18:50,094 --> 00:18:53,100
and the kind of service ie JavaScript or
as we like to call it

303
00:18:54,054 --> 00:18:58,128
OS automation JavaScript and what the
underlying engine is the same

304
00:18:59,028 --> 00:19:03,034
just a proclamation is quite different
from running scripts in your browser

305
00:19:03,034 --> 00:19:07,083
when used as capron mention you can do
everything that you as the Mac user can

306
00:19:07,083 --> 00:19:07,157
do

307
00:19:08,057 --> 00:19:10,148
this is very different from browser
scripts that don't have access to your

308
00:19:11,048 --> 00:19:12,056
personal data

309
00:19:12,056 --> 00:19:16,062
the applications on your Mac and browser
scripts you might expect the window

310
00:19:17,016 --> 00:19:18,095
object or a document object

311
00:19:18,095 --> 00:19:21,098
not gonna have those here you have a
host a different objects you can

312
00:19:21,098 --> 00:19:21,180
interact with

313
00:19:22,008 --> 00:19:26,023
automate your Mac so how exactly was
this brought

314
00:19:26,095 --> 00:19:30,178
to JavaScript what a recap applications
have scripting dictionaries

315
00:19:31,078 --> 00:19:35,086
detail what can be interacted with and
how an Apple event to use to communicate

316
00:19:35,086 --> 00:19:37,100
with those applications

317
00:19:38,000 --> 00:19:42,052
to bring us the JavaScript core we got
the JavaScript Apple event bridge

318
00:19:42,052 --> 00:19:46,061
that reads those scripting dictionaries
and then use Apple events to communicate

319
00:19:46,061 --> 00:19:47,158
with the applications

320
00:19:48,058 --> 00:19:51,065
another we've seen what does get Prada
mission is

321
00:19:51,065 --> 00:19:55,118
and how it works let's look at how we
can use JavaScript proclamation

322
00:19:56,018 --> 00:20:02,047
beginning with scripting applications

323
00:20:02,047 --> 00:20:06,047
we introduce a application object into a
javascript context

324
00:20:06,047 --> 00:20:09,079
which is the main entrance point all the
scriptable pieces and parts of an

325
00:20:09,079 --> 00:20:10,128
application

326
00:20:11,028 --> 00:20:14,057
sup the most common way to access an
application

327
00:20:14,057 --> 00:20:18,090
is by name here accessing Safari
application

328
00:20:18,009 --> 00:20:21,080
and beyond name we can also access
applications by bundle ID

329
00:20:22,061 --> 00:20:25,140
bypass by process ID

330
00:20:26,004 --> 00:20:30,067
and we can get the application that's
running the script we're currently

331
00:20:31,003 --> 00:20:35,006
n by getting the current application

332
00:20:35,006 --> 00:20:38,079
so now we have this application object
we're gonna want to interact with

333
00:20:38,079 --> 00:20:43,086
let's look at some examples the syntax
for doing just that

334
00:20:44,049 --> 00:20:48,050
accessing properties is accomplished
using dot notation

335
00:20:48,059 --> 00:20:51,144
to access elements do you square
brackets

336
00:20:52,044 --> 00:20:55,109
to call commands you call them as
functions

337
00:20:56,009 --> 00:20:59,014
using print the Seas and you can create
new objects

338
00:20:59,059 --> 00:21:04,143
by calling class constructors as
functions again using practices

339
00:21:05,043 --> 00:21:10,061
Satsuki getting and setting properties
but they were scripting Safari

340
00:21:10,061 --> 00:21:14,075
we create a reference to the first
documented Safari

341
00:21:14,075 --> 00:21:18,082
and now we can do things like get the
documents URL

342
00:21:19,045 --> 00:21:23,133
see apprentices at the end we're calling
this property as a function

343
00:21:24,033 --> 00:21:27,096
because we want to actually send the get
event to the application

344
00:21:27,096 --> 00:21:31,137
and get the string value we don't simply
won a reference to the URL in the

345
00:21:32,037 --> 00:21:32,119
document

346
00:21:33,019 --> 00:21:36,086
you wanna call it as a function and get
that string value

347
00:21:36,086 --> 00:21:39,144
we can also set the documents URL and
this

348
00:21:40,044 --> 00:21:45,117
sends the set event to the application
actually sets the URL

349
00:21:46,017 --> 00:21:49,022
let's say you want to get a particular
window and Safari

350
00:21:49,022 --> 00:21:52,025
well there are three ways to access
elements

351
00:21:52,025 --> 00:21:57,047
jobs for Prada mention by index

352
00:21:57,047 --> 00:22:00,144
by name and by I D

353
00:22:01,044 --> 00:22:04,055
it has benefits and risks associated
with it and it's important to understand

354
00:22:04,055 --> 00:22:06,140
the object model that the application
that you're scripting

355
00:22:07,004 --> 00:22:11,008
to know when it's best to use which

356
00:22:11,044 --> 00:22:15,133
so already with just these basics
beginning some pretty amazing things

357
00:22:16,033 --> 00:22:21,132
let's put it to use first I'd like to
just open up script editor

358
00:22:22,032 --> 00:22:25,060
got a little JavaScript here just ray
JavaScript

359
00:22:25,006 --> 00:22:28,007
creating a string some text

360
00:22:28,007 --> 00:22:32,030
and then I'm going to use Council lot
lot to say I expect in JavaScript to

361
00:22:32,093 --> 00:22:33,187
lock this text

362
00:22:34,087 --> 00:22:37,128
and I log this it's going to show up in
the event lock

363
00:22:38,028 --> 00:22:41,082
and a lower panel summer open the event
log

364
00:22:41,082 --> 00:22:45,114
and if I run the script we see hello
world was line just like we wanted

365
00:22:46,014 --> 00:22:50,051
this is great this in the JavaScript I'm
used to and doing exactly what we wanted

366
00:22:50,051 --> 00:22:53,090
this is hugely useful for debugging we
can log transcript to see what's going

367
00:22:53,009 --> 00:22:54,014
on

368
00:22:55,004 --> 00:22:58,076
but let's say I wanted to write some
taxed and I want it to exist even

369
00:22:59,012 --> 00:23:02,089
after I quit script editor or perhaps on
a style that text

370
00:23:02,089 --> 00:23:05,122
change its finder color and so on

371
00:23:06,022 --> 00:23:12,027
now we can start interacting with
applications to accomplish that

372
00:23:12,027 --> 00:23:15,116
so here we have a text that the document
name flock how many users across a

373
00:23:16,016 --> 00:23:16,113
couple demos

374
00:23:17,013 --> 00:23:20,089
to write some text first

375
00:23:20,089 --> 00:23:25,093
this is a simple script we access the
text that application

376
00:23:26,029 --> 00:23:29,042
we get a reference to the log document

377
00:23:29,042 --> 00:23:32,075
then we set the documents text and we
style it's fine

378
00:23:32,075 --> 00:23:35,131
size and color so before I run this

379
00:23:36,031 --> 00:23:39,059
I'm gonna open the event log and will be
able to see the events that are being

380
00:23:39,059 --> 00:23:40,114
sent to this application

381
00:23:41,014 --> 00:23:44,077
to accomplish this so when I run this
script

382
00:23:44,077 --> 00:23:47,118
we see I love JavaScript was like just
like we wanted

383
00:23:48,018 --> 00:23:51,034
style just like we wanted and the bottom
here we see

384
00:23:51,034 --> 00:23:54,040
all the events that were sent to
accomplish this task

385
00:23:54,094 --> 00:23:57,167
so this is great we have some persistent
taxed it's been beautified just like we

386
00:23:58,067 --> 00:23:58,076
wanted

387
00:23:59,057 --> 00:24:02,102
but what we want to do this multiple
times in the same script

388
00:24:03,002 --> 00:24:06,073
well instead of repeating the
functionality again and again

389
00:24:06,073 --> 00:24:09,145
we're playing in javascript we can write
a function

390
00:24:10,045 --> 00:24:13,112
I've done just that here we have a
function

391
00:24:14,012 --> 00:24:18,029
the exception tax the log an optional
formatting parameter

392
00:24:18,029 --> 00:24:21,104
then just like before we access the text
that

393
00:24:22,004 --> 00:24:26,052
she's me the text that application we
get reference to log document

394
00:24:26,052 --> 00:24:29,098
but now instead of setting the documents
entire text

395
00:24:29,098 --> 00:24:32,101
we're going to appended to the last
paragraph

396
00:24:33,001 --> 00:24:36,006
the Madonna style based on formatting
you pass n

397
00:24:36,006 --> 00:24:39,088
was in default values now we have our
lock

398
00:24:39,088 --> 00:24:42,165
we call it three times at bottom here
passing and parameters

399
00:24:43,065 --> 00:24:47,079
for formatting twice the last time we
use default values

400
00:24:47,079 --> 00:24:50,103
so high running a script

401
00:24:51,003 --> 00:24:54,004
we see that our text was logged just
like we wanted

402
00:24:54,004 --> 00:24:58,059
styled as we wanted this is great reblog
as many times as we want

403
00:24:58,059 --> 00:25:01,127
style any different way that we choose
every single time

404
00:25:02,027 --> 00:25:05,099
sauce this is powerful stuff simply by
accessing

405
00:25:05,099 --> 00:25:08,132
an application an element and a couple
properties

406
00:25:09,032 --> 00:25:12,111
right out of the box power at your
fingertips and it's really easy to

407
00:25:13,011 --> 00:25:17,015
approach

408
00:25:17,015 --> 00:25:21,091
some other ways that we might when
interactive applications

409
00:25:21,091 --> 00:25:25,103
what they were skipping now everyone
access some of the messages in our inbox

410
00:25:26,003 --> 00:25:29,011
but we don't want the entire messages
element Arabian box that's a whole lotta

411
00:25:29,083 --> 00:25:30,084
messages

412
00:25:30,093 --> 00:25:33,124
usually letting wanna get

413
00:25:34,024 --> 00:25:39,035
only the messages whose subject is
JavaScript using the special whose

414
00:25:39,035 --> 00:25:39,090
method

415
00:25:39,009 --> 00:25:42,090
a felony to raise we can do just that by
passing a dictionary

416
00:25:43,071 --> 00:25:47,119
of properties would like to match on
those elements we now receive an array

417
00:25:48,019 --> 00:25:53,030
only containing the elements that match

418
00:25:53,003 --> 00:25:56,034
objects have certain commands that they
can respond to

419
00:25:56,061 --> 00:25:59,158
and you can call this command as methods
locally that send the command events to

420
00:26:00,058 --> 00:26:02,071
the application

421
00:26:02,071 --> 00:26:05,105
so again but they were stripping now

422
00:26:06,005 --> 00:26:09,011
we have a reference to the first message
in our inbox

423
00:26:09,011 --> 00:26:12,012
and we want to open it well

424
00:26:12,012 --> 00:26:16,080
we could tell the message to open we can
also tell mail to

425
00:26:16,008 --> 00:26:21,083
opened the message and both these are
entirely equivalent

426
00:26:22,055 --> 00:26:26,092
some commands take named parameters and
so you accomplish this by passing a

427
00:26:26,092 --> 00:26:28,092
dictionary others named parameters

428
00:26:28,092 --> 00:26:31,146
here for example we're creating a reply
to our message

429
00:26:32,046 --> 00:26:36,111
we're going to apply to everybody and
we're not going to open a window

430
00:26:37,011 --> 00:26:41,099
now remember you can always use the
dictionary viewer in script editor

431
00:26:41,099 --> 00:26:45,131
the scene which name parameters go with
which commands which commands can be

432
00:26:46,031 --> 00:26:47,096
called on which objects and so on

433
00:26:47,096 --> 00:26:50,101
it's a phenomenal tall and really useful
when you're building more complex

434
00:26:51,001 --> 00:26:54,049
scripts

435
00:26:54,049 --> 00:26:58,056
some commands take files as parameters
such as opening a document

436
00:26:59,019 --> 00:27:02,063
using texted to accomplish this

437
00:27:02,063 --> 00:27:05,071
we've introduced a path object into the
environment

438
00:27:05,071 --> 00:27:08,108
you construct with a string that has a
file path inside

439
00:27:09,008 --> 00:27:12,105
and now you can use that path object
anywhere that a file is expected as a

440
00:27:13,005 --> 00:27:14,066
parameter

441
00:27:14,066 --> 00:27:17,094
so we can open a document just like we
want it

442
00:27:17,094 --> 00:27:20,125
be aware but if you pass a string
instead of a path

443
00:27:21,025 --> 00:27:25,109
wherever files expected you will receive
an error

444
00:27:26,009 --> 00:27:29,031
so so we want to create a document
instead of simply opening 1

445
00:27:29,031 --> 00:27:32,059
in fact that well

446
00:27:32,059 --> 00:27:37,153
scripting text that we can call the
document class constructor as a function

447
00:27:38,053 --> 00:27:42,071
but now actually create this object
inside the application

448
00:27:42,071 --> 00:27:45,073
bring it to life we're going to push the
document

449
00:27:45,091 --> 00:27:48,188
onto the documents element array and
that actually create

450
00:27:49,088 --> 00:27:52,164
inside the application then we can
interact with it just like any other

451
00:27:53,064 --> 00:27:54,136
objects inside the application

452
00:27:55,036 --> 00:27:58,067
you get that text for example

453
00:27:58,067 --> 00:28:01,153
and optionally when you create objects
you can pass in a dictionary of

454
00:28:02,053 --> 00:28:02,128
properties

455
00:28:03,028 --> 00:28:06,065
you'd like to have set on that object
when it's created here

456
00:28:06,065 --> 00:28:09,072
we're creating a document passing and
some text when instantiated

457
00:28:10,035 --> 00:28:14,040
we push again under the appropriate
array and it's created inside the

458
00:28:14,004 --> 00:28:14,091
application

459
00:28:15,027 --> 00:28:20,051
living and breathing ready for us to
interact with so this is a wide range of

460
00:28:20,051 --> 00:28:20,140
functionality

461
00:28:21,004 --> 00:28:25,009
inherently available applications
property access element access

462
00:28:25,045 --> 00:28:28,119
con command creating objects but there
are script

463
00:28:29,019 --> 00:28:33,068
plugins funds for scripts and allow you
to extend the functionality of an

464
00:28:33,068 --> 00:28:34,105
application

465
00:28:35,005 --> 00:28:38,089
and the OS has a set of standard
scripting additions

466
00:28:38,089 --> 00:28:42,101
ships these are available from every
scripting environment

467
00:28:43,001 --> 00:28:47,009
including JavaScript proclamation so
let's say that we're scripting the

468
00:28:47,009 --> 00:28:48,056
current application

469
00:28:48,056 --> 00:28:51,131
I want to be able to use the standard
additions to do so

470
00:28:52,031 --> 00:28:56,065
we're going to set the include standard
additions flag to true

471
00:28:56,065 --> 00:28:59,081
and then we can do things I tell the
application to beat

472
00:28:59,081 --> 00:29:04,096
which is hugely useful for debugging
tell the application to speak some text

473
00:29:04,096 --> 00:29:07,109
which extend the functionality to a
wider audience

474
00:29:08,009 --> 00:29:11,066
we can also do things like display
alerts and dialogues which is great

475
00:29:11,066 --> 00:29:12,105
because now we have used in our

476
00:29:13,005 --> 00:29:18,087
skinny user interaction incorporated
with scripting applications

477
00:29:18,087 --> 00:29:21,125
so we've covered a lot of different ways
that we can actually script applications

478
00:29:22,025 --> 00:29:24,074
their object models and so on

479
00:29:24,074 --> 00:29:29,108
let's look at other uses have javascript
running mission

480
00:29:30,008 --> 00:29:33,015
remember earlier me wrapped the logging
functionality and functions we can use

481
00:29:33,078 --> 00:29:35,145
it multiple times from one script

482
00:29:36,045 --> 00:29:40,109
what they want to log from multiple
scripts not just one

483
00:29:41,009 --> 00:29:44,084
this is the perfect use a library

484
00:29:44,084 --> 00:29:47,087
I've taken that log function and I've
saved in a script

485
00:29:48,014 --> 00:29:51,043
named cool box in the script libraries
folder

486
00:29:51,043 --> 00:29:54,062
and now I can access this library and
its functions from

487
00:29:54,062 --> 00:29:58,106
any other script and i right to
accomplish this

488
00:29:59,006 --> 00:30:02,037
I instantiate a library object by name

489
00:30:02,037 --> 00:30:05,046
and file extension is optional and then

490
00:30:05,046 --> 00:30:09,091
I can call those functions as methods on
that library object

491
00:30:09,091 --> 00:30:12,174
so this code would log just like we did
before and the beautiful thing about

492
00:30:13,074 --> 00:30:13,169
libraries

493
00:30:14,069 --> 00:30:17,090
as they can be written in JavaScript and
AppleScript

494
00:30:17,009 --> 00:30:20,076
and used from JavaScript for automation

495
00:30:21,057 --> 00:30:25,094
so now let's take a look how to create
app lets using javascript for automation

496
00:30:25,094 --> 00:30:29,112
app lets our applications saved by
script editor

497
00:30:30,012 --> 00:30:35,026
when you run an outlet the script saved
inside this run

498
00:30:35,026 --> 00:30:38,098
adults have a certain number about
events that you can create handlers for

499
00:30:38,098 --> 00:30:43,127
such as when the apparatus run when the
app lets told open documents or print

500
00:30:44,027 --> 00:30:45,051
documents

501
00:30:45,051 --> 00:30:49,102
there's a special idle handler that
allows you to perform periodic tasks

502
00:30:50,002 --> 00:30:53,074
and you can also create handlers for one
ap lit is reopened

503
00:30:53,074 --> 00:30:56,119
when an app that is quick and just like
libraries

504
00:30:57,019 --> 00:31:01,097
you can have any other functions inside
your ap lit and those can be called

505
00:31:01,097 --> 00:31:05,122
first take a look at an example a basic
ap lit that uses

506
00:31:06,022 --> 00:31:09,091
a script library

507
00:31:09,091 --> 00:31:12,097
here we have a large document like
before

508
00:31:12,097 --> 00:31:17,101
and let's look at the script inside this
applicator

509
00:31:18,037 --> 00:31:21,080
at the top we instantiate our toolbox
library

510
00:31:21,008 --> 00:31:24,019
then in our run handler we log Ron

511
00:31:24,091 --> 00:31:28,092
in green in our idle handler we lie idle
in orange

512
00:31:28,092 --> 00:31:31,125
and in our quit handler Wheelock quit in
red

513
00:31:32,025 --> 00:31:35,071
so if I double clicked this ap lit to
run it

514
00:31:35,071 --> 00:31:38,154
we see that running idle were logged
just like we wanted

515
00:31:39,054 --> 00:31:43,152
and if I go and quit the ap lit we see
that quit was also locked

516
00:31:44,052 --> 00:31:47,059
which is great this is exactly what we
wanted

517
00:31:47,059 --> 00:31:50,135
this is a very basic example using a
couple handlers an app witnessing a

518
00:31:51,035 --> 00:31:51,112
library

519
00:31:52,012 --> 00:31:56,075
but imagine the possibilities here this
is double clickable JavaScript sitting

520
00:31:56,075 --> 00:31:57,083
on my desktop

521
00:31:57,083 --> 00:32:00,084
ready to interact with all the
scriptable applications

522
00:32:00,093 --> 00:32:03,104
script libraries and more

523
00:32:04,004 --> 00:32:07,069
speaking of more we've looked at
scripting the object model of an

524
00:32:07,069 --> 00:32:08,117
application extensively

525
00:32:09,017 --> 00:32:14,024
what you wanna script the user interface
an application

526
00:32:14,087 --> 00:32:17,102
this is accomplished by using
accessibility

527
00:32:18,002 --> 00:32:22,011
which allows applications on your Mac to
interact with your Mac

528
00:32:22,011 --> 00:32:27,088
on your behalf system events uses the
accessibility API's to expose the user

529
00:32:27,088 --> 00:32:28,160
interface and application

530
00:32:29,006 --> 00:32:33,015
and in JavaScript proclamation you use
the system event application

531
00:32:33,069 --> 00:32:36,071
to access the pieces and parts a user
interface

532
00:32:36,071 --> 00:32:39,139
first look at an example

533
00:32:40,039 --> 00:32:43,117
first we're going to access the system
event application

534
00:32:44,017 --> 00:32:47,070
then we're going to access the notes
process

535
00:32:47,007 --> 00:32:50,101
above the system advanced processes
element iraq I'm gonna send it to a

536
00:32:51,064 --> 00:32:51,071
variable

537
00:32:52,034 --> 00:32:55,066
notes you why now we can do things

538
00:32:55,066 --> 00:32:59,079
like close the window by clicking the
first but not the first window

539
00:32:59,079 --> 00:33:03,161
notes user interface but i wanna send
some key strokes in this application

540
00:33:04,061 --> 00:33:08,069
what to do so run access then notes
application itself

541
00:33:09,041 --> 00:33:12,105
and activate it bringing it to the front
and then

542
00:33:13,005 --> 00:33:16,098
we can call the system events keystroke
command

543
00:33:16,098 --> 00:33:19,191
passing in am using command down the
similar to minimize

544
00:33:20,091 --> 00:33:23,190
event to use accessibility

545
00:33:24,009 --> 00:33:27,075
must be enabled in the privacy
preferences for applications like script

546
00:33:28,056 --> 00:33:29,128
editor and so on the use it

547
00:33:30,028 --> 00:33:33,035
and the first time you try to use
accessibility you will be prompted to

548
00:33:33,035 --> 00:33:35,041
enable it

549
00:33:35,041 --> 00:33:38,123
okay so what it another way description
application its user interface

550
00:33:39,023 --> 00:33:43,037
we looked at scripting object models
library is an app lets

551
00:33:43,037 --> 00:33:47,092
now let's look at a more advanced use
JavaScript rodham Asian

552
00:33:47,092 --> 00:33:50,149
using system API's which provide access

553
00:33:51,049 --> 00:33:54,092
to really powerful and important things
like the filesystem

554
00:33:54,092 --> 00:33:59,156
& Co collapse development in javascript

555
00:34:00,056 --> 00:34:03,128
we introduce two objects into the
environment that here means for

556
00:34:04,028 --> 00:34:04,117
interacting

557
00:34:05,017 --> 00:34:08,766
with system APIs obj see and dollar

558
00:34:08,919 --> 00:34:11,012
and for those coming from a browser
environment dollar may mean something

559
00:34:11,849 --> 00:34:13,300
very special to you

560
00:34:13,003 --> 00:34:17,612
but in our environment it's a very
different dollar

561
00:34:17,909 --> 00:34:22,250
I'm seeking be used to do things like
bridging jobs good values

562
00:34:22,025 --> 00:34:28,098
into objective-c bridging objective-c
objects into JavaScript

563
00:34:28,098 --> 00:34:31,787
and importing frameworks that you'd like
to use

564
00:34:32,669 --> 00:34:36,673
so once you imported a framework you can
access it's classes and functions and so

565
00:34:37,069 --> 00:34:37,123
on

566
00:34:37,609 --> 00:34:41,626
using the dollar object and you can also
call dollar

567
00:34:41,779 --> 00:34:45,785
as a function as a shorthand for
bridging JavaScript values

568
00:34:45,839 --> 00:34:49,220
into objective-c

569
00:34:49,022 --> 00:34:52,421
now let's talk about calling methods on
objects well

570
00:34:52,619 --> 00:34:56,470
begin let's look at some objective-c
code

571
00:34:56,047 --> 00:35:00,196
quite simple going to create an ashtray
ng and everyone to write that string to

572
00:35:00,619 --> 00:35:02,730
a file

573
00:35:02,073 --> 00:35:06,432
this is the equivalent javascript::write
a mission code to accomplish this

574
00:35:07,089 --> 00:35:10,710
their couple key things to focus on here
first

575
00:35:10,071 --> 00:35:14,660
the Foundation framework is available to
you out of the box when using javascript

576
00:35:15,299 --> 00:35:16,303
for automation

577
00:35:16,339 --> 00:35:19,980
so we don't need to import foundation

578
00:35:19,098 --> 00:35:23,195
then we use the dollar object to access
the an ashtray in class

579
00:35:24,095 --> 00:35:28,166
we call Alec and because it takes no
parameters we don't need parentheses

580
00:35:29,066 --> 00:35:32,675
we do not use parentheses here then we
call

581
00:35:33,269 --> 00:35:37,210
in it with utf8 string and we're going
to be passing a parameter

582
00:35:37,021 --> 00:35:40,620
so we call it as a function and pass on
our printer

583
00:35:40,809 --> 00:35:44,814
now the method to write to a file is
takes multiple parameters

584
00:35:45,309 --> 00:35:48,960
so we're going to convert the selector
to a Javascript method

585
00:35:48,096 --> 00:35:51,103
name I can cat mating and camel case in
the pieces together

586
00:35:52,066 --> 00:35:57,117
and ima call it as a function passing a
parameter is in the right order

587
00:35:58,017 --> 00:36:03,186
another we've seen how to write to a
file let's actually see it newt's

588
00:36:03,339 --> 00:36:07,386
this is a little script at the top we
create an ashtray

589
00:36:07,809 --> 00:36:11,840
some tax would like to write to a file
then we created an ashram with a file

590
00:36:12,119 --> 00:36:12,960
path

591
00:36:12,096 --> 00:36:15,115
and we call the string by expanding till
then path

592
00:36:16,015 --> 00:36:19,041
method on it to get the full path and
then

593
00:36:19,041 --> 00:36:23,067
we write this string to that file and
when we write this

594
00:36:23,067 --> 00:36:26,156
it's going to appear in this folder here

595
00:36:26,759 --> 00:36:31,400
so if I run this script of I was created

596
00:36:31,004 --> 00:36:35,052
our text was written just like we won
was a phenomenal ok

597
00:36:35,088 --> 00:36:38,143
and this is that simple example but you
can imagine

598
00:36:39,043 --> 00:36:43,046
the power utility that the system APIs
bring to the JavaScript for automation

599
00:36:43,046 --> 00:36:45,595
vir

600
00:36:46,009 --> 00:36:51,088
let's look at other ways that we can
interact with his API's

601
00:36:51,799 --> 00:36:54,822
but so we create a new NS half object
well

602
00:36:55,029 --> 00:36:58,500
access its properties already is dot
notation

603
00:36:58,005 --> 00:37:02,101
so can access the running property get
its boolean value and react accordingly

604
00:37:03,046 --> 00:37:06,165
we can also set its launch pad property

605
00:37:06,579 --> 00:37:10,653
like so missile actually set it on the
object

606
00:37:11,319 --> 00:37:15,720
an interesting thing but the java script
writer mission bridge

607
00:37:15,072 --> 00:37:18,079
is the bridge nail so nil injected see

608
00:37:19,042 --> 00:37:22,094
is somewhat similar to the undefined in
javascript

609
00:37:22,094 --> 00:37:25,933
but they're not exactly the same
different key ways

610
00:37:26,779 --> 00:37:29,858
in objective-c it's absolutely valid
call a method on and no object

611
00:37:30,569 --> 00:37:33,594
and will receive another nail object but
in javascript

612
00:37:33,819 --> 00:37:37,824
if you call a method and undefined
object you will receive an hour

613
00:37:38,319 --> 00:37:42,890
therefore we do not bridge now ended
undefined we keep it as abridged no

614
00:37:42,089 --> 00:37:42,173
object

615
00:37:43,073 --> 00:37:46,121
you can interact with

616
00:37:47,021 --> 00:37:50,115
said create abridged no object we call
the dollar function without

617
00:37:51,015 --> 00:37:56,023
any parameters by Mike you want to
create a bridge no object you asking

618
00:37:56,023 --> 00:38:00,114
well this allows you to accomplish
things like passed by reference

619
00:38:01,014 --> 00:38:04,393
so here we're creating a new NS XML
document

620
00:38:04,519 --> 00:38:08,420
ever going to pass are bridged no object
are error variable

621
00:38:08,042 --> 00:38:12,066
as the third and final Preminger and
will happen behind the scenes

622
00:38:12,066 --> 00:38:17,067
is a banana error object is created the
bridge no object will be replaced by

623
00:38:17,067 --> 00:38:21,100
and now are error variable a point that
and we can use that

624
00:38:22,000 --> 00:38:25,599
so want to create a document we can
check if its male

625
00:38:25,599 --> 00:38:28,720
by calling the is no method on it and if
it is nil

626
00:38:28,072 --> 00:38:31,221
we could for example log the user info
from the

627
00:38:31,869 --> 00:38:37,430
now populated error object

628
00:38:37,043 --> 00:38:40,702
another exciting thing that you can do
using system the PI's subclassing

629
00:38:41,089 --> 00:38:42,136
objects

630
00:38:42,559 --> 00:38:45,611
so accomplished this you call the
register subclass method

631
00:38:46,079 --> 00:38:49,103
RC object you pass in a name

632
00:38:49,319 --> 00:38:53,345
have your subclass its superclass
although this is optional

633
00:38:53,579 --> 00:38:57,700
and will default to and I subject

634
00:38:57,007 --> 00:39:00,646
any protocols that your classmate here
too

635
00:39:01,339 --> 00:39:04,920
properties are defined as an object

636
00:39:04,092 --> 00:39:08,291
where the keys are the names are the
property and values on it typeof the

637
00:39:09,119 --> 00:39:11,168
property

638
00:39:11,609 --> 00:39:15,970
and Methods are again and object where
the keys are the selector

639
00:39:15,097 --> 00:39:18,646
and the value isn't object detailing the
types of the method

640
00:39:19,519 --> 00:39:23,420
and its implementation now if you're
defining a function

641
00:39:23,042 --> 00:39:26,141
our method excuse me has declared in a
protocol

642
00:39:26,519 --> 00:39:30,553
run a superclass the types are optional
for demonstration purposes

643
00:39:30,859 --> 00:39:34,490
we show them here to know what us to use

644
00:39:34,049 --> 00:39:40,064
let's see using a subclass and creating
something using system EPS

645
00:39:40,064 --> 00:39:43,963
so here I have a nap and this is the
script inside

646
00:39:44,539 --> 00:39:48,150
and this produces a Cocoa application

647
00:39:48,015 --> 00:39:51,070
a temperature converter nice little got
for us to use

648
00:39:51,007 --> 00:39:54,012
there to think I'd like to point out for
a actually run s

649
00:39:54,075 --> 00:39:58,122
you'll see at the top the week important
Coco now this allows us to access things

650
00:39:59,022 --> 00:40:01,601
like ass window and so on

651
00:40:01,799 --> 00:40:05,230
we create our windows are inputs and
then

652
00:40:05,023 --> 00:40:08,119
we register a subclass name temperature
converter

653
00:40:09,019 --> 00:40:12,047
that is two methods to convert from
Celsius to Fahrenheit and from

654
00:40:12,047 --> 00:40:13,946
Fahrenheit to Celsius

655
00:40:14,369 --> 00:40:18,371
and you can see that all the logic
inside these methods all the math

656
00:40:18,569 --> 00:40:21,620
is in javascript then

657
00:40:22,079 --> 00:40:26,430
we create a new temperature converter
object how corrupt or inputs

658
00:40:26,043 --> 00:40:30,152
and bring the window to the front so
let's run us

659
00:40:30,539 --> 00:40:35,630
close this here and if I double click
this Apple to run it

660
00:40:35,063 --> 00:40:38,115
we have a nice little Coco application

661
00:40:39,015 --> 00:40:43,924
written entirely in Java Script

662
00:40:44,059 --> 00:40:47,135
course it does what we promise we can
convert Fahrenheit to Celsius

663
00:40:47,819 --> 00:40:50,820
assess Celsius to Fahrenheit and so on

664
00:40:50,829 --> 00:40:56,210
as a little example look at this we can
create a Cocoa application in javascript

665
00:40:56,021 --> 00:40:59,063
imagine what you can do from here with
all this at your fingertips

666
00:40:59,063 --> 00:41:03,091
there is power ready to be used

667
00:41:03,091 --> 00:41:06,124
and definitely make sure to check out
the JavaScript for automation release

668
00:41:07,024 --> 00:41:07,863
notes

669
00:41:08,079 --> 00:41:11,720
we can see other great things you can do
using system APIs

670
00:41:11,072 --> 00:41:14,681
like binding C functions into the
environment

671
00:41:15,329 --> 00:41:18,331
another mechanism for passed by
reference

672
00:41:18,529 --> 00:41:24,930
and also passing functions for boxer
expected

673
00:41:24,093 --> 00:41:28,174
are we've done a beautiful whirlwind
tour all the ways we can use JavaScript

674
00:41:29,074 --> 00:41:30,443
proclamation

675
00:41:31,109 --> 00:41:34,206
for application scripting libraries an
app lets you I scripting

676
00:41:35,079 --> 00:41:38,125
using system API's I'm sure each
everyone he was just bitching to get

677
00:41:38,539 --> 00:41:39,980
your hands on

678
00:41:39,098 --> 00:41:42,171
completely understand before you do
let's talk about where you can use

679
00:41:43,071 --> 00:41:47,150
JavaScript Roc Nation

680
00:41:47,789 --> 00:41:50,836
so as all the demos have shown you can
use JavaScript rodham nation

681
00:41:51,259 --> 00:41:56,390
in script editor you can save Appleton
droplets from script editor

682
00:41:56,039 --> 00:41:59,648
as we saw and run

683
00:41:59,999 --> 00:42:03,050
a cell mentioned and you saw in the
presentation tomorrow

684
00:42:03,509 --> 00:42:07,130
you can say scripts in a system-wide
script menu this phenomenal for scripts

685
00:42:07,013 --> 00:42:08,045
that you're going to use repeatedly

686
00:42:08,045 --> 00:42:11,684
again and again Automator

687
00:42:12,089 --> 00:42:15,137
which allows you to produce workflows

688
00:42:15,569 --> 00:42:19,690
on many applications and processes on
your Mac's now has

689
00:42:19,069 --> 00:42:23,122
are run JavaScript Automator Action that
lets you incorporate JavaScript

690
00:42:24,022 --> 00:42:25,023
proclamation

691
00:42:25,023 --> 00:42:28,044
into your workflows what you've done so

692
00:42:28,044 --> 00:42:32,066
you can save those actions excuse me
those workflows as services

693
00:42:32,066 --> 00:42:37,475
that can be used for many application
and across your system

694
00:42:38,069 --> 00:42:41,098
finally you can use JavaScript
proclamation internal

695
00:42:41,359 --> 00:42:44,452
using OS a script command line tool and
this is great

696
00:42:45,289 --> 00:42:48,310
you can incorporate JavaScript
proclamation into a bash script

697
00:42:48,499 --> 00:42:52,170
and for example display an alert when
you're about to finish a long-running

698
00:42:52,017 --> 00:42:53,926
background process

699
00:42:54,079 --> 00:42:56,156
so we've seen some other places where
you can use JavaScript for automation

700
00:42:56,849 --> 00:42:57,870
already

701
00:42:58,059 --> 00:43:02,400
now let's look at the rest

702
00:43:02,004 --> 00:43:06,703
when I set the scene I work as a
photographer and travel magazine

703
00:43:07,099 --> 00:43:10,150
I think pictures for cover and every
week

704
00:43:10,015 --> 00:43:13,144
I've to send those cover photos to the
same person

705
00:43:13,279 --> 00:43:16,890
to be approved before I can submit them
to print

706
00:43:16,089 --> 00:43:20,068
every week I send the same in our
message to the same person

707
00:43:20,869 --> 00:43:23,970
and on changing are the pictures

708
00:43:23,097 --> 00:43:28,171
so I whipped up a little droplet here

709
00:43:29,071 --> 00:43:33,140
using the open document handler that
accesses the mail application

710
00:43:34,004 --> 00:43:38,032
creates a new mail message for us using
some freak and content

711
00:43:38,068 --> 00:43:41,197
it then uses that contact application

712
00:43:41,809 --> 00:43:44,884
to get my recipient and the email
message gets their name in the email

713
00:43:45,559 --> 00:43:46,635
address

714
00:43:47,319 --> 00:43:50,345
puts on a message and then for each
other pictures that we've dropped in

715
00:43:50,579 --> 00:43:50,658
this droplet

716
00:43:51,369 --> 00:43:55,407
ran Adams attachments to the message
activate mail and have it ready to send

717
00:43:55,749 --> 00:43:59,750
whenever I'd like so

718
00:43:59,759 --> 00:44:02,795
here are some other photos I talk I
happen to know the last three are the

719
00:44:03,119 --> 00:44:04,460
most beautiful

720
00:44:04,046 --> 00:44:08,053
summit drop those right here under this
droplet

721
00:44:09,016 --> 00:44:12,093
our mail messages created a contents
there are recipients they're

722
00:44:12,093 --> 00:44:15,096
and all the pictures we wanted are ready
for us to go

723
00:44:16,023 --> 00:44:19,882
my workflow was cut from a hundred
percent down to

724
00:44:20,089 --> 00:44:23,400
5 Penn 0 percent

725
00:44:23,004 --> 00:44:26,693
this made my life easier and while I
have the script

726
00:44:27,089 --> 00:44:31,650
open I'd like to mention another problem
that I have

727
00:44:31,065 --> 00:44:34,147
I read a lot of jobs for Prada mission
as you might expect I regularly have

728
00:44:35,047 --> 00:44:36,096
script editor windows open

729
00:44:36,096 --> 00:44:39,174
multiples of what what's sometimes I'm
writing a library then

730
00:44:40,074 --> 00:44:43,413
I'm gonna use another script and I want
to be able to see everything at the same

731
00:44:44,079 --> 00:44:46,079
time

732
00:44:46,079 --> 00:44:49,176
so before halftime the automation tryin
I might have had to drag these windows

733
00:44:50,049 --> 00:44:51,078
around the screen

734
00:44:51,339 --> 00:44:54,930
resize them make sure corners are
overlapping each other and so on and so

735
00:44:54,093 --> 00:44:55,682
forth

736
00:44:56,519 --> 00:44:59,578
but then I realized what I automated so

737
00:45:00,109 --> 00:45:05,160
I whipped up this script here that
accesses the script editor application

738
00:45:05,016 --> 00:45:09,135
and get all the windows and then using
the number of windows and the size of

739
00:45:09,279 --> 00:45:10,285
the screen

740
00:45:10,339 --> 00:45:13,930
it carefully meticulously
programmatically

741
00:45:13,093 --> 00:45:17,522
tiles the windows around the screen
based on their size

742
00:45:18,359 --> 00:45:23,440
so if I run this from the script menu
cuz I use it so frequently

743
00:45:23,044 --> 00:45:26,423
we see all of my windows were piled
exactly as I wanted

744
00:45:26,819 --> 00:45:30,730
I can see everything all the same time
this is beautiful for developing

745
00:45:30,073 --> 00:45:35,097
multiple scripts at the same time so I
used JavaScript for automation

746
00:45:35,097 --> 00:45:38,188
to make writing JavaScript for
automation even easier

747
00:45:39,088 --> 00:45:46,088
powerful its flexible and it's
everywhere

748
00:45:50,019 --> 00:45:53,092
now speaking of flexibility and power
and everywhere

749
00:45:53,092 --> 00:45:57,181
in fact we've proven to ourselves how
easy it is

750
00:45:58,009 --> 00:46:02,230
to extend popular text editors for
JavaScript like sublime taxed and taxed

751
00:46:02,023 --> 00:46:02,119
me

752
00:46:03,019 --> 00:46:06,578
to extend them to execute JavaScript
proclamation code

753
00:46:06,749 --> 00:46:11,777
that were writing in those applications
and to prove it to you how easy it is to

754
00:46:12,029 --> 00:46:15,054
write down mister Prada mission anywhere
in run

755
00:46:15,279 --> 00:46:19,330
we flipped up this automated workflow

756
00:46:19,789 --> 00:46:23,980
that uses the new run JavaScript action

757
00:46:23,098 --> 00:46:28,117
what we do is we access the content up
the front most document

758
00:46:29,017 --> 00:46:32,396
we evaluate that is a script then

759
00:46:32,549 --> 00:46:36,950
we display the result and we optionally
copy it to the clipboard

760
00:46:36,095 --> 00:46:40,097
if we'd like I've save this as a service

761
00:46:41,015 --> 00:46:44,484
and I'm a patch that service to a hotkey
some now

762
00:46:44,619 --> 00:46:47,662
my hope work is very very slim

763
00:46:48,049 --> 00:46:52,930
easy to do I am would like you to notice
I mean text edit right now

764
00:46:52,093 --> 00:46:55,952
I've just a proclamation code Britain in
a document

765
00:46:56,789 --> 00:47:00,817
so using that automated workflow is a
service attacks this hockey

766
00:47:01,069 --> 00:47:05,190
I can wrongness cold executing

767
00:47:05,019 --> 00:47:09,020
from the text edit ID in you that I love
so much that I've created using

768
00:47:09,002 --> 00:47:11,091
javascript for automation

769
00:47:11,289 --> 00:47:14,311
we get ours all with a copy to the
clipboard

770
00:47:14,509 --> 00:47:17,558
not right now thank you and soul that's

771
00:47:17,999 --> 00:47:21,007
amazing I just run JavaScript formation
from text edit

772
00:47:21,079 --> 00:47:24,470
missus to show that you can use
JavaScript proclamation

773
00:47:24,047 --> 00:47:27,576
how you'd like where you'd like
extraordinarily extensible and

774
00:47:27,999 --> 00:47:33,031
extraordinarily flexible

775
00:47:33,319 --> 00:47:36,414
and as we mentioned before you can use
JavaScript proclamation

776
00:47:37,269 --> 00:47:41,130
for terminal using the OS a script
command line tool

777
00:47:41,013 --> 00:47:45,067
so let's look at an example

778
00:47:45,067 --> 00:47:48,686
we're going to con the OS a script
command line tool with a couple flags

779
00:47:49,289 --> 00:47:54,200
gonna be using the JavaScript language
we want a result the print a source

780
00:47:54,002 --> 00:47:57,611
and the past and some javascript to run
this is the

781
00:47:57,809 --> 00:48:00,902
this is what I talked about before we
can display an alert so maginnis me part

782
00:48:01,739 --> 00:48:02,802
in a batch process at the end

783
00:48:03,369 --> 00:48:06,456
the torch show us an alert when our
processes up to finish

784
00:48:07,239 --> 00:48:11,242
so if I run this our letters displayed
just like we won

785
00:48:11,269 --> 00:48:14,650
which is great we get our result

786
00:48:14,065 --> 00:48:17,066
we can react accordingly if we wanted
and another

787
00:48:17,066 --> 00:48:20,089
really exciting new feature a voice a
script is it

788
00:48:20,089 --> 00:48:24,518
interactive mode so a variety of
programming languages like Ruby and

789
00:48:25,319 --> 00:48:25,880
Python

790
00:48:25,088 --> 00:48:28,947
have interactive nods that allow you to
interactively program in those

791
00:48:29,739 --> 00:48:30,740
environments

792
00:48:30,749 --> 00:48:36,220
and now this is possible from OS a
script sup

793
00:48:36,022 --> 00:48:40,411
to do so minute call us a script I
languages JavaScript

794
00:48:40,609 --> 00:48:44,708
I'm gonna pass the dash I flag the same
going in interactive mode

795
00:48:45,599 --> 00:48:50,230
not a demo this interactive mode I'm
gonna be interacting with Safari

796
00:48:50,023 --> 00:48:53,032
so I'm going to create a variable

797
00:48:53,239 --> 00:48:59,130
set it to the Safari application we see
it Safari was activated for us

798
00:48:59,013 --> 00:49:02,014
make it a little better to see

799
00:49:02,014 --> 00:49:05,663
that we can do things like create a
reference to this

800
00:49:05,789 --> 00:49:09,960
first window letting want to get that
Windows name

801
00:49:09,096 --> 00:49:12,935
in simply called the Name property is a
function favorites like we expect that's

802
00:49:13,799 --> 00:49:14,640
great

803
00:49:14,064 --> 00:49:17,273
was a lot of fun what's spice it up a
bit

804
00:49:17,849 --> 00:49:20,895
let's create a new pad add that to the
window in real time

805
00:49:21,309 --> 00:49:25,388
interactively first will create a new
tab

806
00:49:26,099 --> 00:49:30,170
and more have the URL be Apple acecomm

807
00:49:30,017 --> 00:49:33,166
then to actually create this in the
application

808
00:49:33,319 --> 00:49:38,180
I'm going to push it onto the windows
tabs element iraqi

809
00:49:38,018 --> 00:49:42,066
and before I do know I know that I wanna
bring the tab in the front when I do

810
00:49:42,066 --> 00:49:42,143
this

811
00:49:43,043 --> 00:49:46,192
and I i can't quite remember I think
it's the front

812
00:49:46,579 --> 00:49:51,430
tab or there's a property that I can 7 a
window to bring to the front

813
00:49:51,043 --> 00:49:55,122
so were acting with this live before I
do this let's make sure they know what

814
00:49:55,509 --> 00:49:55,562
I'm doing

815
00:49:56,039 --> 00:49:59,045
to bring up script editor I'm gonna

816
00:49:59,099 --> 00:50:03,930
access the library window and let's see

817
00:50:03,093 --> 00:50:06,472
lhasa Safari scripting dictionary great

818
00:50:07,309 --> 00:50:10,365
okay we'll look at the Safari sweet yes
window thank you

819
00:50:10,869 --> 00:50:13,963
%ah the current path not the front at
excuse me

820
00:50:14,809 --> 00:50:19,190
South have this property I know exactly
how to create

821
00:50:19,019 --> 00:50:22,838
how to set the tab to the current tab
bring it to the front

822
00:50:23,009 --> 00:50:26,090
so if I push on the array and bring the
tab to the front

823
00:50:26,819 --> 00:50:29,915
we've just now live interactively added
the tab in this window

824
00:50:30,779 --> 00:50:36,812
had a whole lotta fun in the process

825
00:50:37,109 --> 00:50:40,400
and beyond being a cool way to interact
with applications

826
00:50:40,004 --> 00:50:43,593
this is phenomenal for exploring their
script ability for learning JavaScript

827
00:50:43,989 --> 00:50:45,021
for automation

828
00:50:45,309 --> 00:50:48,950
it's great tool to have

829
00:50:48,095 --> 00:50:52,254
part so we've covered what I was to
produce nation s

830
00:50:53,109 --> 00:50:58,400
how it works how you can use it where
you can use it

831
00:50:58,004 --> 00:51:03,123
to summarize task a proclamation is
built on JavaScript core

832
00:51:03,519 --> 00:51:07,910
modern JavaScript environment and it's
built on the open scripting architecture

833
00:51:07,091 --> 00:51:12,142
which has been part of the Mac OS since
before OS 10

834
00:51:13,042 --> 00:51:17,151
javascript::write nation has been
integrated system wide all layers

835
00:51:17,529 --> 00:51:20,534
from high-level application scripting to
system services

836
00:51:21,029 --> 00:51:26,680
to use in the terminal and accessing
system API us

837
00:51:26,068 --> 00:51:29,437
and as we saw Talisker proclamations
flexible

838
00:51:30,049 --> 00:51:33,390
it allows you to accomplish tasks and
solve problems

839
00:51:33,039 --> 00:51:36,047
the best way that you see fit

840
00:51:36,047 --> 00:51:39,926
sup our call to action today is go out

841
00:51:40,349 --> 00:51:43,413
and script the script herbal
applications on your Mac

842
00:51:43,989 --> 00:51:47,071
for app developers make your application
scriptable so other people can script

843
00:51:47,809 --> 00:51:50,670
and do amazing things

844
00:51:50,067 --> 00:51:53,089
and make sure to tell others to make
their application scriptable

845
00:51:53,089 --> 00:51:56,142
the is an already we have a phenomenal
ecosystem

846
00:51:57,042 --> 00:52:02,139
we're really excited for more more
applications to join it every day

847
00:52:03,039 --> 00:52:07,008
the checkout documentation make sure to
