# Compatibility — Bash 3.
|
|
#
|
|
# OSX won't update Bash 3 (last updated circa 2009) to Bash 4,
|
|
# and we'd like this completion script to work on both Linux and Mac.
|
|
#
|
|
# For example, OSX Yosemite (released circa 2014) ships with Bash 3:
|
|
#
|
|
# $ echo $BASH_VERSION
|
|
# 3.2
|
|
#
|
|
# While Ubuntu LTS 14.04 (a.k.a. Trusty, also released circa 2016)
|
|
# ships with the latest version, Bash 4 (updated circa 2016):
|
|
#
|
|
# $ echo $BASH_VERSION
|
|
# 4.3
|
|
#
|
|
|
|
# Testing
|
|
#
|
|
# (1) Invoke « shellcheck »
|
|
#
|
|
# * source: « https://github.com/koalaman/shellcheck »
|
|
# * run: « shellcheck ./share/bash-completion/completions/home-manager »
|
|
#
|
|
# (2) Interpret via Bash 3
|
|
#
|
|
# * run: « bash --noprofile --norc ./share/bash-completion/completions/home-manager »

# NOTES
|
|
#
|
|
# (1) the « sed -n -e 's/.../.../p' » invocation:
|
|
#
|
|
# * the « -e '...' » option takes a Sed Script.
|
|
# * the « -n » option only prints when « .../p » would print.
|
|
# * the « s/xxx/yyy/ » Sed Script substitutes « yyy » whenever « xxx » is matched.
|
|
#
|
|
# (2) the « '^................ : id \([[:alnum:]]\+\) -> .*' » regular expression:
|
|
#
|
|
# * matches « 199 », for example, in the line « 2019-03-13 15:26 : id 199 -> /nix/store/mv619y9pzgsx3kndq0q7fjfvbqqdy5k8-home-manager-generation »
