Fast rake autocompletion plugin.
This script caches the output for later usage and significantly speeds it up. It generates a .rake_tasks cache file in parallel to the Rakefile. It also checks the file modification dates to see if it needs to regenerate the cache file.
This plugin caches the output for later usage and significantly speeds it up.
It generates a `.rake_tasks` cache file in parallel to the Rakefile. It also
checks the file modification time to see if it needs to regenerate the cache
file.
This is entirely based on [this pull request by Ullrich Schäfer](https://github.com/robb/.dotfiles/pull/10/), which is inspired by [this Ruby on Rails trick from 2006](http://weblog.rubyonrails.org/2006/3/9/fast-rake-task-completion-for-zsh/).

Think about that. 2006.
----------
Since August of 2016, it also checks if it's in a Rails project and looks at
rake files inside `lib/tasks` and their modification time to know if the
cache file needs to be regenerated.
## Installation
Just add the plugin to your `.zshrc`:
```bash
plugins=(foo bar rake-fast)
```zsh
plugins=(... rake-fast)
```
You might consider adding `.rake_tasks` to your [global .gitignore](https://help.github.com/articles/ignoring-files#global-gitignore)
## Usage
`rake`, then press tab
Type `rake`, then press tab.
If you want to force the regeneration of the `.rake_tasks` file, run `rake_refresh`.
