[![Build Status](https://travis-ci.org/mfaerevaag/wd.png?branch=master)](https://travis-ci.org/mfaerevaag/wd)
`wd` (*warp directory*) lets you jump to custom directories in zsh, without using `cd`. Why? Because `cd` seems ineffecient when the folder is frequently visited or has a long path.
### Setup
### oh-my-zsh
`wd` comes bundles with [oh-my-zshell](https://github.com/robbyrussell/oh-my-zsh)!
Just add the plugin in your `~/.zshrc` file:
plugins=(... wd)
#### Automatic
Run either in terminal:
* `curl -L https://github.com/mfaerevaag/wd/raw/master/install.sh | sh`
* `wget --no-check-certificate https://github.com/mfaerevaag/wd/raw/master/install.sh -O - | sh`
#### Manual
* Clone this repo to your liking
* Add `wd` function to `.zshrc` (or `.profile` etc.):
wd() {
. ~/paht/to/wd/wd.sh
}
* Install manpage. From `wd`'s base directory (requires root permissions):
# cp wd.1 /usr/share/man/man1/wd.1
# chmod 644 /usr/share/man/man1/wd.1
Note, when pulling and updating `wd`, you'll need to do this again in case of changes to the manpage.
#### Completion
If you're NOT using [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh) and you want to utelize the zsh-completion feature, you will also need to add the path to your `wd` installation (`~/bin/wd` if you used the automatic installer) to your `fpath`. E.g. in your `~/.zshrc`:
fpath=(~/path/to/wd $fpath)
Also, you may have to force a rebuild of `zcompdump` by running:
$ rm -f ~/.zcompdump; compinit

### Usage
@ -24,6 +76,7 @@
$ wd ...
This is a wrapper for the zsh `dirs` function.
(You might need `setopt AUTO_PUSHD` in your `.zshrc` if you hare not using [oh-my-zshell](https://github.com/robbyrussell/oh-my-zsh)).
* Remove warp point test point:
@ -33,8 +86,55 @@
$ wd ls
* List warp points to current directory
* List warp points to current directory, or optionally, path to given warp point:
$ wd show
* Print usage with no opts or the `help` argument.
* Remove warp points to non-existent directories.
$ wd clean
Use `clean!` to not be prompted with confirmation (force).
* Print usage with no opts or the `help` argument:
$ wd help
* Print the running version of `wd`:
$ wd --version
* Specifically set the config file (default `~/.warprc`), which is useful when testing:
$ wd --config ./file <action>
* Force `exit` with return code after running. This is not default, as it will *exit your terminal*, though required when testing/debugging.
$ wd --debug <action>
* Silence all output:
$ wd --quiet <action>
### Testing
`wd` comes with a small test suite, run with [shunit2](https://code.google.com/p/shunit2/). This can be used to confirm that things are working as it should on your setup, or to demonstrate an issue.
To run, simply `cd` into the `test` directory and run the `tests.sh`.
$ ./tests.sh
### License
The project is licensed under the [MIT-license](https://github.com/mfaerevaag/wd/blob/master/LICENSE).
### Finally
If you have issues, feedback or improvements, don't hesitate to report it or submit a pull-request. In the case of an issue, we would much appreciate if you would include a failing test in `test/tests.sh`. Explanation on how to run the tests, read the section "Testing" in this README.
Credit to [altschuler](https://github.com/altschuler) for awesome idea.
Hope you enjoy!
