Fish: Difference between revisions
Move "Disable man page generation" to its own sub-section. Was a sub-section of "Setting fish as default shell" which is unrelated. |
m Replaced attr def with a inherit, does the same thing. |

It is possible to set fish as the interactive non-login shell for your terminal emulator without setting it as the login shell (the one in <code>/etc/passwd</code>). | |||
As this is usually a user-wise setting, to configure the terminal emulator you will need to either modify its config file, or use [[Home Manager]]. | |||
==== Setting fish as default for Kitty ==== | |||
Using [[Home Manager]]: | |||
{{File|3=programs.kitty = { | |||
enable = true; | |||
shellIntegration.enableFishIntegration = true; | |||
settings = { | |||
shell = "fish"; | |||
}; | |||
};|name=home.nix|lang=nix}} | |||
Note: the <code>shellIntegration.enableFishIntegration = true;</code> is not required for setting fish as default, but provides other useful quality-of-life features, see https://sw.kovidgoyal.net/kitty/shell-integration/. | |||
For use without home-manager, refer to https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.shell and https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.shell_integration. | |||

=== Setting fish as the login shell === | |||
Using fish as the the login shell can cause compatibility issues. For example, certain recovery environments such as systemd's emergency mode to be completely broken when fish was set as the login shell. ArchWiki presents an [https://wiki.archlinux.org/title/Fish#Modify_.bashrc_to_drop_into_fish alternative solution], keeping bash as the system shell but having it exec fish when run interactively. | Using fish as the the login shell can cause compatibility issues.

If you are using Lix, you can change the grep condition to <code>"fish\|nix-shell"</code> so the <code>nix-shell</code> command still works, this is necessary since Lix forks before spawning the shell process so the parent process ends up being nix-shell and not fish.<ref>https://git.lix.systems/lix-project/lix/issues/1131#issuecomment-18341</ref> | |||
↵If you still want to set fish as the login shell, see [[Command Shell#Changing the default shell]]. | |||
