I'm currently using the below code (hacked together) to generate documentation for my git aliases using 'git alias'. This assumes there is a comment above each alias starting with ### and the aliases are formatted as 'alias_name = command'. This works as is but does anyone have a more gooder method? :)
Current code (contents of $HOME/.bin/bin/gdoc
):
grep --no-group-separator -A1 '###' "$HOME"/.gitconfig | awk 'END{if((NR%2))print p}!(NR%2){print$0p}{p=$0}' | sed -re 's/( =)(.*)(###)/:*/g' | awk -F* '{printf "\033[1;31m%-30s\033[0m %s\n", $1, $2}' | sort
Example aliases:
### use difftool to view differences in file
dt = difftool

### add and commit a file, arg1=file, arg2=commit_message
ac = "!cd -- \"${GIT_PREFIX:-.}\" && git add \"$1\" && git commit -m \"$2\" #"
### remove any files that are in gitignore from tracking
ig = "!git rm --cached `git ls-files -i --exclude-from=.gitignore` #"
### print out available aliases
alias = "!$HOME/.bin/bin/gdoc #"
### add a file to gitignore
ignore = "!([ ! -e .gitignore ] && touch .gitignore) | echo $1 >> .gitignore #"
### git rm files that have been deleted without using git
r = "!git ls-files -z --deleted | xargs -0 git rm #"
# https://stackoverflow.com/questions/38057261/git-config-alias-escaping/39616600#39616600
### Quote a sh command, converting it to a git alias string
quote-string = "!read -r l; printf \\\"!; printf %s \"$l\" | sed 's/\\([\\\"]\\)/\\\\\\1/g'; printf \" #\\\"\\n\" #"
### Unquote a git alias command command, converting it to a sh command
quote-string-undo = "!read -r l; printf %s \"$l\" | sed 's/\\\\\\([\\\"]\\)/\\1/g'; printf \"\\n\" #"
### debug git aliases - 'git debug <alias>'
debug = "!set -x; GIT_TRACE=2 GIT_CURL_VERBOSE=2 GIT_TRACE_PERFORMANCE=2 GIT_TRACE_PACK_ACCESS=2 GIT_TRACE_PACKET=2 GIT_TRACE_PACKFILE=2 GIT_TRACE_SETUP=2 GIT_TRACE_SHALLOW=2 git"
Current output:
ac: add and commit a file, arg1=file, arg2=commit_message
alias: print out available aliases
debug: debug git aliases - 'git debug <alias>'
dt: use difftool to view differences in file
ig: remove any files that are in gitignore from tracking
ignore: add a file to gitignore
quote-string-undo: Unquote a git alias command command, converting it to a sh command
quote-string: Quote a sh command, converting it to a git alias string
r: git rm files that have been deleted without using git
