Subject: [PATCH] Add functions and configuration snippets hierarchy
|
||||
|
||||
This allows "vendors" (i.e. third-party upstreams interested in
|
||||
supporting fish) to add auto-loaded functions and eager-loaded
|
||||
configuration "snippets", while still allowing both the user and the administrator to
|
||||
fully override all of that.
|
||||
|
||||
This has been inspired by systemd's configuration hierarchy, and implements a similar scheme
|
||||
whereby files with the same name in higher-ranking directories override files in lower-ranking ones.
|
||||
|
||||
Fixes #1956

+Right after reading /usr/share/fish/config.fish and before reading /etc/fish/config.fish, fish will also read files in ~/.config/fish/conf.d/, /etc/fish/conf.d and /usr/share/fish/vendor_conf.d (the exact values depend on $XDG_CONFIG_HOME, $__fish_sysconfdir and $__fish_datadir). If there are files with the same name in two or all of these, fish will only attempt to read the first (skipping all files with that name if it is unreadable). ~/.config takes precedence over /etc/ which takes precedence over /usr. The path to the latter can also be gotten via `pkg-config` as "confdir", and is meant for third-party applications to integrate with fish.
