-# Using FORTRESS with CD-on-Exit

-

-## Setup (One Time)

-

-Add this line to your `~/.bashrc` or `~/.zshrc`:

-

-```bash

-source ~/Documents/GithubOrgs/FortranGoingOnForty/fortress/fortress.sh

-```

-

-Then reload your shell:

-```bash

-source ~/.bashrc  # or source ~/.zshrc

-```

-

-## Usage

-

-Instead of running `fpm run`, use the `fortress` command:

-

-```bash

-fortress

-```

-

-This runs the fortress file explorer. When you're browsing:

-

-1. Use `↑↓` to navigate files/directories

-2. Use `→` to enter a directory

-3. Use `←` to go back

-4. **Press `c` on any directory to exit fortress and CD your shell to that directory**

-5. Press `q` to quit without changing directory

-

-## How It Works

-

-When you press `c`:

-1. FORTRESS writes the selected directory path to `~/.fortress_cd`

-2. FORTRESS exits

-3. The shell function reads `~/.fortress_cd` and runs `cd` to that directory

-4. The temp file is cleaned up

-

-This is the same pattern used by tools like `fzf`.

-

-## Important Notes

-

-- ❌ `fpm run` does NOT enable cd-on-exit (it runs directly)

-- ✅ `fortress` command DOES enable cd-on-exit (uses the shell function)

-- You must source `fortress.sh` in your shell config for this to work

-- This only works in interactive shells, not in scripts
