A single-file Vim plugin manager.
|
|
|
|
Somewhere between [Pathogen](https://github.com/tpope/vim-pathogen) and
|
|
[Vundle](https://github.com/gmarik/vundle), but with faster parallel installer.
|
|
|
|
|
|
|
|
### Pros.
|
|
|
|
- Easier to setup
|
|
- Parallel installation/update (requires
|
|
[+ruby](http://junegunn.kr/2013/09/installing-vim-with-ruby-support/))
|
|
- Smallest possible feature set
|
|
- Branch/tag support
|
|
- On-demand loading
|
|
- Dependency resolution using `Plugfile` (experimental)
|
|
|
|
### Cons.
|
|
|
|
- Everything else
|
|
|
|
### Usage

### FAQ/Troubleshooting
|
|
|
|
#### Plugins are not installed/updated in parallel
|
|
|
|
Your Vim does not support Ruby interface. `:echo has('ruby')` should print 1.
|
|
In order to setup Vim with Ruby support, you may refer to [this
|
|
article](http://junegunn.kr/2013/09/installing-vim-with-ruby-support).
|
|
|
|
#### *Vim: Caught deadly signal SEGV*
|
|
|
|
If your Vim crashes with the above message, first check if its Ruby interface is
|
|
working correctly with the following command:
|
|
|
|
```vim
|
|
:ruby puts RUBY_VERSION
|
|
```
|
|
|
|
If Vim crashes even with this command, it is likely that Ruby interface is
|
|
broken, and you have to rebuild Vim with a working version of Ruby.
|
|
(`brew remove vim && brew install vim` or `./configure && make ...`)
|
|
|
|
If you're on OS X, one possibility is that you had installed Vim with
|
|
[Homebrew](http://brew.sh/) while using a Ruby installed with
|
|
[RVM](http://rvm.io/) or [rbenv](https://github.com/sstephenson/rbenv) and later
|
|
removed that version of Ruby.
|
|
|
|
[Please let me know](https://github.com/junegunn/vim-plug/issues) if you can't
|
|
resolve the problem. In the meantime, you can set `g:plug_threads` to 1, so that
|
|
Ruby installer is not used at all.
|
|
|
|
#### Errors on fish shell
|
|
|
|
If vim-plug doesn't work correctly on fish shell, you might need to add `set
|
|
shell=/bin/sh` to your .vimrc.
|
|
|
|
Refer to the following links for the details:
|
|
- http://badsimplicity.com/vim-fish-e484-cant-open-file-tmpvrdnvqe0-error/
|
|
- https://github.com/junegunn/vim-plug/issues/12
|
|
|
|
#### Freezing plugin version with commit hash
|
|
|
|
vim-plug does not allow you to freeze the version of a plugin with its commit
|
|
hash. This is by design. I don't believe a user of a plugin should be looking
|
|
at its individual commits. Instead, one should be choosing the right version
|
|
using release tags or versioned branches (e.g. 1.2.3, stable, devel, etc.)
|
|
|
|
```vim
|
|
Plug 'junegunn/vim-easy-align', '2.9.2'
|
|
```
|
|
|
|
If the repository doesn't come with such tags or branches, you should think of
|
|
it as "unstable" or "in development", and always use its latest revision.
|
|
|
|
If you really must choose a certain untagged revision, consider forking the
|
|
repository.
