extrakto for tmux

Output completions - you can complete commands that require you to retype text that is already on the screen. This works everywhere, even in remote ssh sessions.

You can fuzzy find your text instead of selecting it by hand:

• press tmux prefix + tab to start extrakto
• fuzzy find the text/path/url/line
• use custom filters (ctrl + f)
• press
  • tab to insert it to the current pane,
  • enter to copy it to the clipboard,
• see other features in HELP (press ctrl-h in extrakto)

Use it for paths, URLs, options from a man page, git hashes, docker container names, ...

Requirements

• tmux - popups require 3.2, otherwise extrakto will open in a split window.
• fzf
• Python 3.6+
• Bash (tested with 5.0+, on macOS please brew install bash first)

Supported clipboards:

• Linux Xorg (xclip) and Wayland (wl-copy)
• macOS (pbcopy)
• WSL (aka "Bash on Windows")
• bring your own

Installation with Tmux Plugin Manager

Add the plugin to the list of TPM plugins in .tmux.conf:

set -g @plugin 'laktak/extrakto'

Hit prefix + I to fetch the plugin and source it.

You should now have all extrakto key bindings defined.

Manual Installation

Clone the repo:

$ git clone https://github.com/laktak/extrakto ~/clone/path

Add this line to the bottom of .tmux.conf:

run-shell ~/clone/path/extrakto.tmux

Reload the tmux environment:

# type this in terminal
$ tmux source-file ~/.tmux.conf

You should now have all extrakto key bindings defined.

Options

To set any of these options write on your ~/.tmux.conf file:

set -g <option> "<value>"

Where <option> and <value> are one of the specified here:

Option	Default	Description
@extrakto_key	tab	The key binding to start. If you have any special requirements (like a custom key table) set this to 'none' and define a binding in your .tmux.conf. See extrakto.tmux for a sample.
@extrakto_split_direction	a	Whether the tmux split will be auto, popup, vertical or horizontal
@extrakto_split_size	7	The size of the tmux split (for vertical/horizontal)
@extrakto_popup_size	90%	Set width and height of the tmux popup window. Set this to w,h to set the width to w and height to h.
@extrakto_popup_position	C	Set position of the tmux popup window. Possible values are in the display-popup entry in man tmux. Set this to x,y to set the x and y positions to x and y respectively.
@extrakto_grab_area	full	Whether you want extrakto to grab data from the recent area, the full pane, all current window's recent areas or all current window's full panes. You can also set this option to any number you want (or number preceded by "window ", e.g. "window 500"), this allows you to grab a smaller amount of data from the pane(s) than the pane's limit. For instance, you may have a really big limit for tmux history but using the same limit may end up on having slow performance on Extrakto.
@extrakto_clip_tool	auto	Set this to whatever clipboard tool you would like extrakto to use to copy data into your clipboard. auto will try to choose the correct clipboard for your platform.
@extrakto_clip_tool_run	bg	Set this to fg to have your clipboard tool run in a foreground shell (enabling remote clipboard support).
@extrakto_fzf_tool	fzf	Set this to path of fzf if it can't be found in your PATH.
@extrakto_fzf_layout	default	Control the fzf layout which is "bottom-up" by default. If you prefer "top-down" layout instead set this to reverse. In fact, this value is passed to the fzf --layout parameter. Possible values are: default, reverse and reverse-list
@extrakto_open_tool	auto	Set this to path of your own tool or auto to use your platforms open implementation.
@extrakto_copy_key	enter	Key to copy selection to clipboard.
@extrakto_insert_key	tab	Key to insert selection.
@extrakto_filter_key	ctrl-f	Key to toggle filter mode.
@extrakto_grab_key	ctrl-g	Key to toggle grab mode.
@extrakto_edit_key	ctrl-e	Key to run the editor.
@extrakto_open_key	ctrl-o	Key to run the open command.
@extrakto_filter_order	word all line	Filter modes order. The first listed mode will be the default when opening extrakto.

Example:

set -g @extrakto_split_size "15"
set -g @extrakto_clip_tool "xsel --input --clipboard" # works better for nvim
set -g @extrakto_copy_key "tab"      # use tab to copy to clipboard
set -g @extrakto_insert_key "enter"  # use enter to insert selection

Custom Filters

You can define your own filters by creating a file in ~/.config/extrakto/extrakto.conf:

[quote]
regex: ("[^"\n\r]+")

To override an existing filter copy it to your file first.

See extrakto.conf for syntax and predefined filters.

CLI

You can also use extrakto as a standalone tool to extract tokens from text.

Installation

For now simply clone the repository and link to the tool somewhere in your path:

git clone https://github.com/laktak/extrakto
cd extrakto
# assuming you `export PATH=$PATH:~/.local/bin` in your `.bashrc`:
ln -s $PWD/extrakto.py ~/.local/bin/extrakto

Requires Python 3.6+.

CLI Usage

usage: extrakto.py [-h] [--name] [-w] [-l] [--all] [-a ADD] [-p] [-u] [--alt] [-r] [-m MIN_LENGTH] [--warn-empty]
