This commit introduces `home.sessionSearchVariables` option, that is
created to be a "generic" version of `home.sessionPath` for any
environment variables that is similar to PATH (e.g.: MANPATH). This
allows composition of those variables between multiple modules, avoiding
issues like this one:
https://github.com/nix-community/home-manager/pull/4579/files#r1364374048
This commit also reimplements `home.sessionPath` as terms of
`home.sessionSearchVariables`, to reduce code duplication and show that
the code is correct.
The behavior is to prepend the new search paths. This will allow
the user to override the defaults easily by setting it later in the
configuration.
Standardize all 'programs.<PROGRAM>.enable<SHELL>Integration' options
with the following new functions:
- lib.hm.shell.mkBashIntegrationOption
- lib.hm.shell.mkFishIntegrationOption
- lib.hm.shell.mkIonIntegrationOption
- lib.hm.shell.mkNushellIntegrationOption
- lib.hm.shell.mkZshIntegrationOption
These functions should default to their corresponding global option:
- home.shell.enableBashIntegration
- home.shell.enableFishIntegration
- home.shell.enableIonIntegration
- home.shell.enableNushellIntegration
- home.shell.enableZshIntegration
All these global options default to the
'home.shell.enableShellIntegration' value.
This hierarchy standardizes the shell integration and increases end-user
flexibility.
BREAKING CHANGE: The following inconsistent default values change from
'false' to 'true':
- programs.zellij.enableBashIntegration
- programs.zellij.enableFishIntegration
- programs.zellij.enableZshIntegration
