# dircycle

Plugin for cycling through the directory stack

This plugins enables directory navigation similar when using back and forward on browsers or common file explorers like Finder or Nautilus.

This is a small zle trick that lets you cycle your directory stack left or right using Ctrl+Shift+Left/Right. This is useful when moving back and forth between directories in development environments, and can be thought of as kind of a nondestructive pushd/popd.

## Enabling the plugin

1. Open your `.zshrc` file and add `dircycle` in the plugins section:

   ```zsh
   plugins=(
       # all your enabled plugins
       dircycle
   )
   ```

2. Reload the source file or restart your Terminal session:

   ```console
   $ source ~/.zshrc
   $
   ```

## Usage Examples

Say you opened these directories on the terminal:

```console
~$ cd Projects
~/Projects$ cd Hacktoberfest
~/Projects/Hacktoberfest$ cd oh-my-zsh
~/Projects/Hacktoberfest/oh-my-zsh$ dirs -v
0       ~/Projects/Hacktoberfest/oh-my-zsh
1       ~/Projects/Hacktoberfest
2       ~/Projects
3       ~
```

By pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>, the current working directory or `$CWD` will be from `oh-my-zsh` to `Hacktoberfest`. Press it again and it will be at `Projects`.

And by pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd>, the `$CWD` will be from `Projects` to `Hacktoberfest`. Press it again and it will be at `oh-my-zsh`.

Here's a example history table with the same accessed directories like above:

| Current `$CWD`  | Key press                                             | New `$CWD`      |
| --------------- | ----------------------------------------------------- | --------------- |
| `oh-my-zsh`     | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `Hacktoberfest` |
| `Hacktoberfest` | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `Projects`      |
| `Projects`      | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `~`             |
| `~`             | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `Projects`      |
| `Projects`      | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `Hacktoberfest` |
| `Hacktoberfest` | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `oh-my-zsh`     |
| `oh-my-zsh`     | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `~`             |

Note the last traversal, when pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> on a last known `$CWD`, it will change back to the first known `$CWD`, which in the example is `~`.

Here's an asciinema cast demonstrating the example above:

## Functions

| Function             | Description                                                                                               |
| -------------------- | --------------------------------------------------------------------------------------------------------- |
| `insert-cycledleft`  | Change `$CWD` to the previous known stack, binded on <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd> |
| `insert-cycledright` | Change `$CWD` to the next known stack, binded on <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd>    |

You can bind these functions to other key sequences, as long as you know the bindkey sequence:

For example, these commands bind to Alt+Shift+Left/Right in xterm-256color:
```
bindkey '^[[1;4D' insert-cycledleft
bindkey '^[[1;4C' insert-cycledright
```

You can get the bindkey sequence pressing <kbd>Ctrl</kbd> + <kbd>V</kbd>, then pressing the keyboard shortcut you want to use.
