It uses a small zle trick that lets you cycle through your directory stack left or right using <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd> / <kbd>Right</kbd> . 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. Restart the shell or restart your Terminal session: + + ```console + $ exec zsh + $ + ``` + +## 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: + +[![asciicast](https://asciinema.org/a/204406.png)](https://asciinema.org/a/204406) + +## 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> | + +## Rebinding keys + +You can bind these functions to other key sequences, as long as you know the bindkey sequence.
