User:Sam/ebuild wrapper

I use a small wrapper for ebuild(1) inspired by slyfox's e. It also makes use of gitify in /etc/portage/bashrc.

I create the following files and add ~/bin to PATH. I also have ~/bin/ebuild as a symlink to ~/bin/e.

FILE ~/bin/ebuild

#!/usr/bin/env bash
# Originally based on https://github.com/trofi/home/blob/ff297b2b6fe51fd0ab226f92c19b5717598b568d/bin%2Fe
# Note that this is used with https://github.com/gentoo-haskell/gentoo-haskell/blob/master/projects/doc/hacking-tips.rst#gitify-your-ebuilds-in-prepare-phase

# WARNING: Note that there's some weird unicode characters around '!=' which I can't remove from mediawiki, please retype the if statement if copy/pasting!
if [[ $0 == *@(ebuild|/home/sam/bin/ebuild) ]] ; then
        # Only gitify ${WORKDIR} if invoked as 'e', not 'ebuild'
        export GITIFY=no
fi

# ln -s ~/bin/e ~/bin/e-{asan,ubsan,lto} && chmod +x ~/bin/e-{asan,ubsan,lto}
if [[ $0 == *@(e-asan|/home/sam/bin/e-asan) ]] ; then
        export FEATURES="-sandbox -usersandbox nostrip -splitdebug"
        export CFLAGS="$(portageq envvar CFLAGS) ${CFLAGS} -ggdb3 -fsanitize=address"
