[pacman-dev] [PATCH] libmakepkg: Add basic rules to lint makepkg.conf variables

Eli Schwartz eschwartz at archlinux.org
Thu Feb 8 04:44:03 UTC 2018


Currently the only things we check are:

- Things that should be arrays, are not strings, and vice versa (this
  was mostly copy-pasted from the similar code in lint_pkgbuild).
- Variables that are meant to contain pathname components cannot contain
  a newline character, because newline characters in pathnames are weird
  and also don't play well with future changes intended for the
  --packagelist option.
