Fish automatic integration taken as an example.
Just like fish, Elvish checks `XDG_DATA_DIRS` for its modules.
Thus, Fish integration in zig is reused, and integration in
Elvish now removes `GHOSTTY_FISH_XDG_DIR` environment variable
on launch.
- contains `.elv` file that implements the core of Elvish integration.
- does not contain routines needed for automatic integration.
- stored in `./elvish/lib/...` in preparation for automatic integration:
Elvish imports `.../elvish/lib/*.elv`.
checklist:
- no confirmation on close where the cursor is at prompt:
works, only occasionally doesn't, I'm not yet sure when.
- new terminals start in pwd of previously focused terminal: works
- prompts resize correctly: works
- triple-click while holding `ctrl` selects output of a command:
works (when mouse is over the output)
- cursor at the prompt is turned into a bar: works
- ghostty:`jump_to_prompt` scrolls through prompts: works
- `opt`-click moves cursor at the prompt: works
- `sudo` preserves ghostty terminfo:
untested - not sure when this is needed exactly, but did not encounter
any errors after sudo, either
This change adds automatic bash shell detection and integration.
Unlike our other shell integrations, bash doesn't provide a built-in
mechanism for injecting our ghostty.bash script into the new shell
environment.
Instead, we start bash in POSIX mode and use the ENV environment
variable to load our integration script, and the rest of the bash
startup sequence becomes the responsibility of our script to emulate
(along with disabling POSIX mode).
This adds a new option to the shell integration feature set, `no-title`.
If this option is set, the shell integration will not automatically
update the window title.
