+# 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 or [ghostty.org](https://ghostty.org/docs)
+
+## Implementation Details
+
+### Bash
+
+Automatic [Bash](https://www.gnu.org/software/bash/) shell integration works by
+starting Bash in POSIX mode and using the `ENV` environment variable to load
+our integration script (`bash/ghostty.bash`). This prevents Bash from loading
+its normal startup files, which becomes our script's responsibility (along with
+disabling POSIX mode).
+
+Bash shell integration can also be sourced manually from `bash/ghostty.bash`.
+This also works for older versions of Bash.
+
+```bash
+# Ghostty shell integration for Bash. This must be at the top of your bashrc!
+if [ -n "${GHOSTTY_RESOURCES_DIR}" ]; then
+    builtin source "${GHOSTTY_RESOURCES_DIR}/shell-integration/bash/ghostty.bash"
+fi
+```
+
+> [!NOTE]
+>
+> The version of Bash distributed with macOS (`/bin/bash`) does not support
+> automatic shell integration. You'll need to manually source the shell
+> integration script (as shown above). You can also install a standard
+> version of Bash from Homebrew or elsewhere and set it as your shell.
+
+### Elvish
+
+For [Elvish](https://elv.sh), `$GHOSTTY_RESOURCES_DIR/src/shell-integration`
+contains an `./elvish/lib/ghostty-integration.elv` file.
+
+Elvish, on startup, searches for paths defined in `XDG_DATA_DIRS`
+variable for `./elvish/lib/*.elv` files and imports them. They are thus
+made available for use as modules by way of `use <filename>`.
+
+Ghostty launches Elvish, passing the environment with `XDG_DATA_DIRS` prepended
+with `$GHOSTTY_RESOURCES_DIR/src/shell-integration`. It contains
+`./elvish/lib/ghostty-integration.elv`. The user can then import it
+by `use ghostty-integration` every time after shell startup or
+autostart integration in `$XDG_CONFIG_HOME/elvish/rc.elv`,
+which will run the integration routines.
+
+If you decide to autostart `ghostty-integration` with `rc.elv`, you should
+detect whether the terminal is Ghostty or not. To do this, add this to the end
+of your `rc.elv` file:
+
+```elvish
+if (eq $E:TERM "xterm-ghostty") {
+  try { use ghostty-integration } catch { }
+}
+```
+
+The [Elvish](https://elv.sh) shell integration is supported by
+the community and is not officially supported by Ghostty. We distribute
+it for ease of access and use but do not provide support for it.
+If you experience issues with the Elvish shell integration, I welcome
+any contributions to fix them. Thank you!
+
+### Fish
+
+For [Fish](https://fishshell.com/), 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](https://fishshell.com/docs/current/language.html).
+
+### Nushell
+
+For [Nushell](https://www.nushell.sh/), Ghostty prepends to the
+`XDG_DATA_DIRS` directory, making the `ghostty` module available through
+Nushell's vendor autoload mechanism. Ghostty then automatically imports
+the module using the `-e "use ghostty *"` flag when starting Nushell.
+
+Nushell provides many shell features itself, such as `title` and `cursor`,
+so our integration focuses on Ghostty-specific features like `sudo`,
+`ssh-env`, and `ssh-terminfo`.
+
+The shell integration is automatically enabled when running Nushell in Ghostty,
+but you can also load it manually is shell integration is disabled:
+
+```nushell
+source $GHOSTTY_RESOURCES_DIR/shell-integration/nushell/vendor/autoload/ghostty.nu
+use ghostty *
+```
+
+### Zsh
+
+Automatic [Zsh](https://www.zsh.org/) integration works by temporarily setting
+`ZDOTDIR` to our `zsh` directory. An existing `ZDOTDIR` environment variable
+value will be retained and restored after our shell integration scripts are
+run.
+
+However, if `ZDOTDIR` is set in a system-wide file like `/etc/zshenv`, it will
+override Ghostty's `ZDOTDIR` value, preventing the shell integration from being
+loaded. In this case, the shell integration needs to be loaded manually.
+
+To load the Zsh shell integration manually:
+
+```zsh
+if [[ -n $GHOSTTY_RESOURCES_DIR ]]; then
+  source "$GHOSTTY_RESOURCES_DIR"/shell-integration/zsh/ghostty-integration
+fi
+```
+
+Shell integration requires Zsh 5.1+.

+# bash-preexec.sh -- Bash support for ZSH-like 'preexec' and 'precmd' functions.
+# https://github.com/rcaloras/bash-preexec
+#
+#
+# 'preexec' functions are executed before each interactive command is
+# executed, with the interactive command as its argument. The 'precmd'
+# function is executed before each prompt is displayed.
+#
+# Author: Ryan Caloras (ryan@bashhub.com)
+# Forked from Original Author: Glyph Lefkowitz
+#
+# V0.6.0
+#
+
+# General Usage:
+#
+#  1. Source this file at the end of your bash profile so as not to interfere
+#     with anything else that's using PROMPT_COMMAND.
+#
+#  2. Add any precmd or preexec functions by appending them to their arrays:
+#       e.g.
+#       precmd_functions+=(my_precmd_function)
+#       precmd_functions+=(some_other_precmd_function)
+#
+#       preexec_functions+=(my_preexec_function)
+#
+#  3. Consider changing anything using the DEBUG trap or PROMPT_COMMAND
+#     to use preexec and precmd instead. Preexisting usages will be
+#     preserved, but doing so manually may be less surprising.
+#
+#  Note: This module requires two Bash features which you must not otherwise be
+#  using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. If you override
+#  either of these after bash-preexec has been installed it will most likely break.
+
+# Tell shellcheck what kind of file this is.
+# shellcheck shell=bash
+
+# Make sure this is bash that's running and return otherwise.
+# Use POSIX syntax for this line:
+if [ -z "${BASH_VERSION-}" ]; then
