## zgen



A lightweight plugin manager for Zsh inspired by [Antigen](https://github.com/zsh-users/antigen). Keep your `.zshrc` clean and simple.



Zgen provides you a few simple commands for managing plugins. It installs your plugins and generates a static init script that will source them for you every time you run the shell. We do this to save some startup time by not having to execute time consuming logic (plugin checking, updates, etc). This means that you have to manually check for updates (`zgen update`) and reset the init script (`zgen reset`) whenever you add or remove plugins.



The motive for creating zgen was to have plugins quickly installed on a new machine without getting the startup lag that Antigen used to give me.



## Installation



Clone the zgen repository



    git clone https://github.com/tarjoilija/zgen.git "${HOME}/.zgen"



Edit your .zshrc file to load zgen



    # load zgen

    source "${HOME}/.zgen/zgen.zsh"



Place the following code after the one above to load oh-my-zsh for example, see Usage for more details



    # if the init script doesn't exist

    if ! zgen saved; then



      # specify plugins here

      zgen oh-my-zsh



      # generate the init script from plugins above

      zgen save

    fi



## Usage



### oh-my-zsh



This is a handy shortcut for installing oh-my-zsh plugins. They can be loaded using `zgen load` too with a significantly longer format.

#### Load oh-my-zsh base

It's a good idea to load the base components before specifying any plugins.



    zgen oh-my-zsh



#### Load oh-my-zsh plugins



    zgen oh-my-zsh 



#### Example



    zgen oh-my-zsh

    zgen oh-my-zsh plugins/git

    zgen oh-my-zsh plugins/sudo

    zgen oh-my-zsh plugins/command-not-found

    zgen oh-my-zsh themes/arrow



### Prezto



#### Load Prezto



    zgen prezto



This will create a symlink in the `ZSHDOT` or `HOME` directory. This is needed by prezto.



#### Load prezto plugins



    zgen prezto 



This uses the Prezto method for loading modules.



#### Load a repo as Prezto plugins



    zgen pmodule  



This uses the Prezto method for loading the module. It creates a symlink and calls `pmodule`.



#### Set prezto options



    zgen prezto   



This must be used before the module is loaded. Or if the default modules should be loaded (default) these settings must be done before the `zgen prezto` command. `module` is prepended if the name does not start with `module`, `prezto` or a `*`, `prezto` is prepended if it does not start with `prezto`.



### General zgen functions



#### Load plugins and completions



    zgen load  [location] [branch]



Zgen tries to source any scripts from `location` using a "very smart matching logic". If it fails to find any, it will appends `location` to `$fpath`.



- `repo`

    - github `user/repository` or path to a repository

    - currently supported formats for a repository path:

        - any local repository

        - `git://*`

        - `https://*`

        - `http://*`

        - `ssh://*`

        - `git@*:*/*`

- `location`

    - relative path to a script/folder

    - useful for repositories that don't have proper plugin support like `zsh-users/zsh-completions`

- `branch`

    - specifies the git branch to use



#### Bulk load plugins



    zgen loadall 



Please see example `.zshrc` for usage.



#### Generate init script

    zgen save



It is recommended to save the plugin sourcing part to a static init script so we don't have to go through the time consuming installing/updating part every time we start the shell (or source .zshrc)



#### Remove init script

    zgen reset



Removes the init script so it will be created next time you start the shell. You must run this every time you add or remove plugins to trigger the changes.



This will not remove the plugins physically from disk.



#### Check for an init script

    zgen saved

Returns 0 if an init script exists.



#### Update all plugins and reset

    zgen update



Pulls updates on every plugin repository and removes the init script.



#### Update zgen

    zgen selfupdate



#### Watch files for modifications

You can automate the process of running `zgen reset` by specifying a list of files to `ZGEN_RESET_ON_CHANGE`. These files will be checked and if a change is detected zgen reset is called.



```zsh

ZGEN_RESET_ON_CHANGE=(${HOME}/.zshrc ${HOME}/.zshrc.local)

```



## Notes

Be aware that `zgen` tries to handle [`compinit`][compinit] for you to allow for the fastest possible initialization times. However, this functionality will be disabled if you've already called `compinit` yourself before sourcing `zgen.zsh`. Alternatively, you can disable it yourself by disabling `$ZGEN_AUTOLOAD_COMPINIT`.



  [compinit]:  "Zsh manual 20.2.1: Use of compinit"



## Example .zshrc



```zsh

# load zgen

source "${HOME}/.zgen/zgen.zsh"



# if the init scipt doesn't exist

if ! zgen saved; then

    echo "Creating a zgen save"



    zgen oh-my-zsh



    # plugins

    zgen oh-my-zsh plugins/git

    zgen oh-my-zsh plugins/sudo

    zgen oh-my-zsh plugins/command-not-found

    zgen load zsh-users/zsh-syntax-highlighting

    zgen load /path/to/super-secret-private-plugin



    # bulk load

    zgen loadall <
