Inspirations

Thanks for the zealdocs/zeal: Offline documentation browser inspired by Dash, and I used to use it a lot for documentation browsering. However, I find the built-in browser frustrate me a lot. I'm a vim user, and in browser, I use Surfingkyes to complete most of the actions. Therefore, I modify the original Zeal so that I'm used to.

The modifications are mainly in:

• [-] Remove the built-in browser.
• [-] Remove configuration dialog, config by editing the "zeal.ini" file directly.
• [+] Support "AND" logical search, namely, for example, the search term "str find" will show the items contains "str" and "find" at the same time.
• [+] Open the result with the custom software.
• [+] PDF documentations are supported.
• [+] Customizable file type association

Custom association

Syntax:

[associations]
filetypes=pdf,html
pdf_regex=\\.pdf$|\\.pdf%7C
pdf_spliter=%7C
pdf_command="\"e:/GreenSoftware/Office/PDFEditor/PDFXEdit.exe\"  /A nameddest=\"\"\"{$2}\"\"\"\"\" \"{$1}\""
html_regex=\\.html?$|\\.html?#
html_command=e:/GreenSoftware/Internet/centbrowser/chrome.exe -url \"{%}\"

Explanation:

1. At the very beginning, the filetypes are given at [associations/filetypes], splitted by comma, for example, there are two types are defined, e.g., pdf and html.
2. Then, there are several information for each association: a) *_regex or *_match: To determine if the current file matches the type or not, if matches, this program will use the corresponding comand defined later. If both are defined, *_regex is used, e.g. *_match is ignored. b) *_command: define the command to be executed, with several macros available. c) *_splitter: define a splitter string to be used and explained later.
3. The filetype judgement follows the order defined by [associations/filetypes], if one of the pattern is matched, the rest are ignored.

*_regex and *_match

The program use these two on the full path to judge the filetype. The full path is in the uri scheme, for example, the filepath in the database is Command The Comprehensive LATEX Symbol List.pdf|Mathematical symbols with the docset stored in e:\Code\ZealT\docsets\software.docset\, the obtained filepath is file:///e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf%7CMathematical symbols. Please note that, the | is escaped as %7C.

For *_regex, the program use regex expression for judgement. To be more specific, use Regex.indexIn(...) != -1.

For *_regex, the program use wildchar mode for judgement. To be more specific, first Regex.setPatternSyntax(QRegExp::Wildcard); and then use rx.exactMatch(strFilepath).

For example, to match a word documenta, you can use the following configuration:

word_match=*.doc?
word_command="\"c:\Program Files\Microsoft Office\root\Office16\WINWORD.EXE\" \"{%}\""

*_splitter

The program use the splitter defined by *_splitter (default: %7C is not given) to split the uri into several groups.

*_command

The macro for the command line are:

macros	Explanation
{%}, {$0}	the full uri, for example: file:///e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf%7CMathematical symbols
{$1}, {$2}, ..., {$9}	different group

Example:

pdf_command="\"e:/GreenSoftware/Office/PDFEditor/PDFXEdit.exe\"  /A nameddest=\"\"\"{$2}\"\"\"\"\" \"{$1}\""

In batch console, we can use

e:/GreenSoftware/Office/PDFEditor/PDFXEdit.exe /A nameddest="Mathematical symbols" "e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf"

to locate the bookmark "Mathematical symbols" in file "e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf".

To avoid the quotes to be incorrectly placed when called by QProcess.startDetached(), we should escape the quote in the midlle of a parameter, namely, after the nameddest=, and the corresponding one. The escaped version is:

e:/GreenSoftware/Office/PDFEditor/PDFXEdit.exe /A nameddest="""Mathematical symbols""" "e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf"

In the database, the path is given as The Comprehensive LATEX Symbol List.pdf|Mathematical symbols. Then uri obtained is file:///e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf%7CMathematical symbols, with the defined seperator %7C, two groups are obtained:

1. file:///e:/Code/ZealT/docsets/software.docset/Contents/Resources/Documents/The Comprehensive LATEX Symbol List.pdf
2. Mathematical symbols

Again, to generate a quote read by QSettings, the quote should be escaped with \. Therefore, we get the final pdf_command.
