Docker wrapper script
I wrote a script to add ShellCheck to any system running Docker, without actually installing anything. I put this into /usr/local/bin/shellcheck
:
#!/bin/bash -
for last; do true; done
docker run --rm -iv "$( cd "$( dirname -- "${last}" )" && pwd )":/mnt koalaman/shellcheck "${@:1:$(($#-1))}" "$(basename -- "${last}")"
This works on Docker for Mac as well as a Linux system running Docker. I have tested it when calling shellcheck
in any of these forms:
shellcheck filename.sh
shellcheck ../../filename.sh
cat filename.sh | shellcheck -
shellcheck -V
No modification of my editor settings was needed for this to integrate (I checked Vim through syntastic and VSCode).
Windows Git-bash Docker wrapper script
I'd like to have a documented how-to for beginners on Windows. Personally, I use Docker in git-bash. I don't know if this is a "common setup". I came up with this first attempt, which could go into the wiki:
#!/bin/bash
exec docker run --rm -v "$(cygpath -aw .):/mnt" koalaman/shellcheck:stable "$@"
Emacs auto-fix script
This function and keymap add the ability to auto-insert the appropriate shellcheck disable=
directive in your script. With thanks to https://github.com/flycheck/flycheck/issues/1436
