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).
Shell Integration Code
This is the shell-specific shell-integration code that is used for the shell-integration feature set that Ghostty supports.
This README is meant as developer documentation and not as user documentation. For user documentation, see the main README.
Implementation Details
Bash
The bash shell integration must currently be sourced manually
from bash/ghostty.bash.
Fish
For Fish, Ghostty prepends to the
XDG_DATA_DIRS directory. Fish automatically loads configuration
files in <XDG_DATA_DIR>/fish/vendor_conf.d/*.fish on startup,
allowing us to automatically integrate with the shell. For details
on the Fish startup process, see the
Fish documentation.
Zsh
For zsh, Ghostty sets ZDOTDIR so that it loads our configuration
from the zsh directory. The existing ZDOTDIR is retained so that
after loading the Ghostty shell integration the normal Zsh loading
sequence occurs.
