yaxg

Yet Another X Grabber script

Dependencies

• slop - for selecting regions and windows
• maim - for saving screenshots
• ffmpeg - for recording videos
• byzanz - for recording gifs (soon to be replaced with ffmpeg)
• libnotify / notify-send - for notifications

Usage

yaxg [OPTIONS] [FILE]

Options

-d  specify duration to record for (only works for webms)
-D  specify delay
-F  overwrite file if it exists
-s  select a region or window
-S  pass a arguments directly to slop
-e  execute a script in the config dir or a callback string with the current $SHELL
-g  save as gif (will be overridden by file extension)
-p  save as png (will be overridden by file extension)
-w  save as webm (will be overridden by file extension)
    this is the default behavior when -g or -p is not present and the filename doesn't end in png or gif
    press Ctrl+C to stop recording or run `yaxg stop`
-v  increase verbosity (can be stacked)
    first level will show errors parsing config file, consecutive levels will be passed to ffmpeg
-h  print this help

Special Strings

Similar to scrot, the callback and filename parameters can take format specifiers that are expanded when encountered. Characters preceded by % are interpreted directly by the date commmand. See man strftime for examples. Characters preceded by $ are parsed by yaxg and expanded as such:

$f  quoted image path/filename (only available in callback)
$w  image width
$h  image height

Configuration

A configuration file can saved to ~/.config/yaxg/conf
If a line begins with # it is treated as a comment and ignored.
The config file accepts the following values:

callback
  a callback string to execute
  if callback is a script in the config dir, the the quoted filename will automatically be passed to the script
filename
  a default filename to use when none is provided (must not include extension)
	defaults to %FT%R:%S:%:z_$wx$h
format
  default format to use, must be either 'png', 'webm', or 'gif'
slop
  arguments to be passed to slop

Examples

• Example CLI usage:

yaxg '%s-$w-$h'
yaxg '%s-$w-$h' -e 'mv $f ~/images/$f'
yaxg -s -S '-l -c 0.3,0.4,0.6,0.4' -e 'mv $f ~/images/$f && firefox ~/images/$f'
printf '#!/usr/bin/env bash\n\n[[ "$1" =~ png$ ]] && optipng "$1"\n' > ~/.config/yaxg/myScript && chmod +x !#:3 && yaxg -e 'myScript'

• Example config file:

filename  %c - $wx$h
format    png
slop      -l -c 0.3,0.4,0.6,0.4
callback  myScript

The wiki has some example callback scripts.

Installation

Arch Linux users can install from the AUR as yaxg-git via their favorite AUR helper.

If you're on another distro, I would suggest cloning the repo and symlink'ing the script into ~/.local/bin and adding that to your PATH.
