Love you man~

Very cool. You at all interested in putting that into plug.vim to toggle on? Though it might be a bit more useful as a perhaps a search command in left pane? If not, we can at least put this in the wiki faq I guess.

@starcraftman Well, I'd like to avoid making vim-plug dependent on external services, and the result of VimAwesome API doesn't seem flawless; missing plugins, duplicate results, etc. Moreover, I'm not convinced if the site is being actively maintained: vim-awesome/vim-awesome#61

Yeah, we should put this on the wiki page (a link on "Home" page or maybe a separate page?) since this compensates for the missing :PluginSearch from Vundle.

@junegunn Ah damn, seems their main dev(s) got busy. Should probably give em a hand, do love that site. The duping problem is a real bummer.

Separately, have you ruled out ever adding PlugSearch or just didn't because vim.org wasn't great to search against?

@starcraftman In my opinion, vim.org no longer functions as the central repository. I don't even publish my plugins there anymore. Regarding the command, I know that some people want PluginSearch equivalent in vim-plug, but I personally don't see the point of it. Don't we all have web browsers? :) Also I don't think it has to be a part of vim-plug, it can be a separate plugin.

Yeah, I think it should be a plugin of its own, doesn't have to be limited to a specific plugin manager.

@junegunn I guess your right. Separate plugin makes most sense, searching isn't really part of plugin management.

Do hope VimAwesome isn't abandoned. Only just realized Gundo hadn't gotten a patch in a year. Sad when good software falls by wayside. :/

@junegunn Neat! :-)

@starcraftman If it's still working for you, by all means, keep it. Otherwise I enjoy using https://github.com/mbbill/undotree

VimAwesome isn't dead, though the main developer (@divad12) does seem to be busy. There was a bit of activity a couple of months ago, and he was quick to respond to pull requests. I can't speak for the project or its maintainers, but I'd guess that pull requests would be well received based on my limited experience with it.

This is epic

Great

where should i put the file (vimawesome.vim) in case to combine with my vundle ?
is there a README.md for installing this ?

u're awesome dude!!

@mirzalazuardi Place the file in ~/.vim/plugin directory or simply paste the code onto your .vimrc.

@junegunn, when I tried using this, it was failing for me with some Open.uri from kernel is deprecated. I did a little bit of searching and fixed it by only using URI.open(URL) instead of open(URL).

Here is the updated code:

  let prefix = matchstr(strpart(getline('.'), 0, col('.') - 1), '[.a-zA-Z0-9_/-]*$')

I'm using your script and gvim on Windows shows message:

[vim-plug] vim - Invalid argument: vim - (implicit vim-scripts expansion is deprecated)
