That's a cool idea :+1: . Just quickly looked at the code and I am not sure how much would be involved but definitely would like to try at some point :smile:
Thanks
:+1:
I really like this idea and have wanted this for a while as well. I think that the only way to achieve this is create a custom FZF source that appends the correct file icons in front of the filenames.
The problem with this approach is that we limit the user to using a specific FZF custom source and not have the devicons in all there already defined sources.
I'm willing to take this up and look into this further.
Ok so I've investigated it some more, and what I found so far is:
Creating a custom source where we execute the default FZF_DEFAULT_COMMAND
and prepend the icon for each resulting line seems like a really cumbersome way to do this.
nonetheless altough it took me a full afternoon (I'm a vimscript novice) I got it done (adding icons to fzf) see below screenshot:
The only part left is getting FZF to actually edit the file because now it tries to edit (icon + filename) as a path.
@alexanderjeurissen Nice! Very cool. So this is for FZF in the terminal (executable)? Your previous comment I thought it was just the vim plugin of FZF.
The only part left is getting FZF to actually edit the file because now it tries to edit (icon + filename) as a path.
Ah yup, I had a similar struggle with CtrlP (eventually sending a PR to more easily do some things).
Not sure if it will be of any help to your particular case but this is how I was stripping out the glyphs for CtrlP: https://github.com/ryanoasis/vim-devicons/blob/master/plugin/webdevicons.vim#L505-L509
@ryanoasis DONE.
code:
" Files + devicons
function! Fzf_dev()
function! s:files()
let files = split(system($FZF_DEFAULT_COMMAND), '\n')
return s:prepend_icon(files)
endfunction
function! s:prepend_icon(candidates)
let result = []
for candidate in a:candidates
let filename = fnamemodify(candidate, ':p:t')
let icon = WebDevIconsGetFileTypeSymbol(filename, isdirectory(filename))
call add(result, printf("%s %s", icon, candidate))
endfor
return result
endfunction
function! s:edit_file(item)
let parts = split(a:item, ' ')
let file_path = get(parts, 1, '')
execute 'silent e' file_path
endfunction
call fzf#run({
\ 'source': <sid>files(),
\ 'sink': function('s:edit_file'),
\ 'options': '-m -x +s',
\ 'down': '40%' })
endfunction
as I said the only downside of this approach is that people have to use this function.. as we require control over the source
and sink
options π’ But it makes use of the $FZF_DEFAULT_COMMAND
which is nice because that is where people specify if they want to use find or ag etc.
this function however doesn't include buffer files and MRU, not sure if that's a deal breaker for a lot of people. We could add them ofc but then we have to offer multiple variants or options ;)
And to answer your question: Yes this is only for using fzf in vim, the standalone fzf.vim plugin isn't required though.
I'll tackle some of the problems mentioned in my previous comment and refine the code. Expect a PullRequest somewhere this weekend. In the mean time people like ( @mhartington ) can use the snippet above ;-)
@alexanderjeurissen Any movement on this by chance?
@michaelmior the code snippet that i shared in a previous comment still works. However it is required that the user specifies this in their vimrc.
I so far haven't found time to work on implementing this in the devicons vim plugin. I don't expect to have spare time to work on this till september. So if people think it's a high priority feature, they can use the code I provided as a starting point for the implementation.
Another fzf user here. I tried the snippet from @alexanderjeurissen without much success. Anything else needed to get it working?
@dvcrn @alexanderjeurissen's snippet works on my setup. Just calling :FZF
won't work, you need to issue :call Fzf_dev()
once you've copied the snippet to your .vimrc.
If you want preview you can install the rouge gem: gem install rouge
and use this code
" Files + devicons
function! Fzf_dev()
let l:fzf_files_options = '--preview "rougify {2..-1} | head -'.&lines.'"'
function! s:files()
let l:files = split(system($FZF_DEFAULT_COMMAND), '\n')
return s:prepend_icon(l:files)
endfunction
function! s:prepend_icon(candidates)
let l:result = []
for l:candidate in a:candidates
let l:filename = fnamemodify(l:candidate, ':p:t')
let l:icon = WebDevIconsGetFileTypeSymbol(l:filename, isdirectory(l:filename))
call add(l:result, printf('%s %s', l:icon, l:candidate))
endfor
return l:result
endfunction
function! s:edit_file(item)
let l:pos = stridx(a:item, ' ')
let l:file_path = a:item[pos+1:-1]
execute 'silent e' l:file_path
endfunction
call fzf#run({
\ 'source': <sid>files(),
\ 'sink': function('s:edit_file'),
\ 'options': '-m ' . l:fzf_files_options,
\ 'down': '40%' })
endfunction
@dkarter great solution! There is a simple way to use the 'internal' fzf.vim preview ( fzf#vim#with_preview
)? Trying it without success.
I've tried using the two Fzf_dev()
commands proposed here (nvim 0.2.3-dev on macos) and it produces no results. I suspect $FZF_DEFAULT_COMMAND
might be part of my problem (it's not defined in my env) ? How can I debug an empty file list being returned? Standard FZF
works fine, but is (obviously) missing the devicons.
Follow-up: looks like installing fd
via homebrew and then setting FZF_DEFAULT_COMMAND
to fd --type f
as described in the FZF docs allows the snippets to work for me. I don't think FZF_DEFAULT_COMMAND
is strictly required for normal fzf use, but I'm fine with this change.
I use ag
aka The Silver Searcher as my FZF_DEFAULT_COMMAND
, which IMO is great because:
.gitignore
files in your project~/.agignore
If you want the same setup install via homebrew (macOS):
brew install the_silver_searcher
and add this to your .vimrc
:
let $FZF_DEFAULT_COMMAND = 'ag --hidden -l -g ""'
If you want it to be even faster - use ripgrep
brew install ripgrep
and add this to your .vimrc
:
let $FZF_DEFAULT_COMMAND = 'rg --hidden -l ""'
Compared with fd
the above are many orders of magnitude faster in my experiments.
@dkarter Good solution. The preview command can be simplified into this:
let l:fzf_files_options = '--preview "rougify {2..} | head -'.&lines.'"'
Here 2..
means columns from 2nd to last, which compose the expected filename.
@dkarter These lines in edit_file(item)
function has problem when the filename contains white spaces.
let l:parts = split(a:item, ' ')
let l:file_path = get(l:parts, 1, '')
Suggest replacing it by the following:
let l:pos = stridx(a:item, ' ')
let l:file_path = a:item[pos+1:]
Thanks @wfxr! I've updated my comment above to include your improvements.
@dkarter also, to remove the dependency of the rouge
gem, you can use this:
let l:fzf_file_options = '--preview "[[ \$(file --mime {2..-1}) =~ binary ]] && echo {2..-1} is a binary file || (highlight -O ansi -l {2..-1} || coderay {2..-1} || rougify {2..-1} || cat {2..-1}) 2> /dev/null | head -'.&lines.'"'
which tries the different supported highlighting programs and finally defaults to cat.
You can take advantage of the neovim async api with the following:
function! Fzf_dev(no_git) abort
let s:file_list = ['']
let s:callbacks = {
\ 'on_stdout': 'OnEvent',
\ 'on_exit': 'OnExit'
\ }
if !a:no_git
call jobstart([ 'rg', '--files' ], s:callbacks)
else
call jobstart([ 'rg', '-L', '-i', '--no-ignore', '--files' ], s:callbacks)
endif
function! OnEvent(job_id, data, event)
let s:file_list[-1] .= a:data[0]
call extend(s:file_list, a:data[1:])
endfunction
function! OnExit(job_id, data, event)
call fzf#run({
\ 'source': s:prepend_icon(s:file_list),
\ 'sink': function('s:edit_file'),
\ 'options': '-m',
\ 'down': '40%'
\ })
endfunction
function! s:prepend_icon(candidates)
let l:result = []
for l:candidate in a:candidates
let l:filename = fnamemodify(l:candidate, ':p:t')
let l:icon = WebDevIconsGetFileTypeSymbol(l:filename, isdirectory(l:filename))
call add(l:result, printf('%s %s', l:icon, l:candidate))
endfor
return l:result
endfunction
function! s:edit_file(item)
let l:pos = stridx(a:item, ' ')
let l:file_path = a:item[l:pos+1:-1]
execute 'silent e' l:file_path
endfunction
endfunction
Then it can be called with a 1
or 0
if you want to search only the files tracked by git, or all files in the project
Used @dkarter's comment as a starting point, and made some performance improvements and added some git diff support as well.
TLDR: Wrote a tool to do the devicon lookup in Rust (so it actually doesn't depend on this repo at all), and used bat
for the previewing. The Rust lookup is about 10x faster than the VIM only implementation, and allows streaming before all results are populated. Directories that took ~4.5 seconds with the VIM implementation, finished near instantaneously with the Rust version.
You can install both with
cargo install bat
cargo install devicon-lookup
And here is the VIM config (also includes support for emulating :GFiles?
):
" Files + devicons
function! Fzf_files_with_dev_icons(command)
let l:fzf_files_options = '--preview "bat --color always --style numbers {2..} | head -'.&lines.'"'

See my blog post for the long form write up! https://coreyja.com/blog/2018/11/17/vim-fzf-with-devicons.html
@coreyja Looks great, but all icons show up as question marks. Any idea why?
@jonasstenberg hmm do you have a nerd font compatible font installed? And do you see Dev icons elsewhere, assuming you have this, vim-devicons, plugin installed?
@coreyja
@jonasstenberg hmm do you have a nerd font compatible font installed?
I installed these fonts using brew, no luck though.
And do you see Dev icons elsewhere
Not sure where to look if I can see them elsewhere?
assuming you have this, vim-devicons, plugin installed?
vim-devicons
is installed.
Thanks for the quick reply!
My bad, had to switch font in iTerm2 as well.
Awesome job with the devicons!
@jonasstenberg Ahh! Glad you got it figured out! Hope you enjoy and let me know if you run into other issues!
@coreyja this is very cool, but it seems to fail for .txt
files on my machine...I'm guessing because devicon-lookup
is not finding a symbol for that file type (although I believe there is as devicon for CMakeLists.txt, however). How should this snippet behave when the icon lookup fails? The failure manifests specifically as trying to open a (nonexistent) path with the first two chars of the path stripped off. This is on macos, if it matters.
@mellery451 ahh sorry you are running into issues. From your description of what happens it sounds like the code that is supposed to chop off the dev char is also chopping off some of your file name. Which is part of the vim script. Are you seeing this with the standard files view or with the git changed files version? I probably won't have time to look into this before the weekend but I'll try to take a look for ya!
Also I might move this little script to a repo, so that we could use the issue tracker and stop using this comment thread!
@coreyja I've only used the standard files view. I think part of the issue might be: https://github.com/coreyja/devicon-lookup/blob/master/src/main.rs#L103 which looks like it returns a single width char (x65 'e') for `txt' which confuses the strip-leading-widechar part of this vim code. Happy to move this discussion to another repo as you suggest. Thanks.
@mellery451 Sorry for the delayed response! I created an issue over on my rust repo, and tagged you in a potential workaround (which I took from @dkarter in this thread)! Here is a link to that issue: https://github.com/coreyja/devicon-lookup/issues/2
Nice ty..glad I found this was really helpful. Noticed that the fzf default_actions (ctrl+x, ctrl+v) weren't working. Seems that is possible to just precall fzf#wrap({}), store the sink function and then modify the returned object. I also needed to change the split file_path index from 1 to 2, could just be me though.
modified @dkarter's code :
function! FZFWithDevIcons()
function! s:files()
let files = split(system('fd --type f'), '\n')
return s:prepend_icon(files)
endfunction
function! s:prepend_icon(candidates)
let result = []
for candidate in a:candidates
let filename = fnamemodify(candidate, ':p:t')
let icon = WebDevIconsGetFileTypeSymbol(filename, isdirectory(filename))
call add(result, printf("%s %s", icon, candidate))
endfor
return result
endfunction
function! s:edit_file(items)
let items = a:items
let i = 1
let ln = len(items)
while i < ln
let item = items[i]
let parts = split(item, ' ')
let file_path = get(parts, 2, '')
let items[i] = file_path
let i += 1
endwhile
call s:Sink(items)
endfunction
let opts = fzf#wrap({})
let opts.source = <sid>files()
let s:Sink = opts['sink*']
let opts['sink*'] = function('s:edit_file')
call fzf#run(opts)
endfunction
I've continued on the work of @TaDaa and the others. What i have now supports devicons, multiselect, preview with highlighting by bat, ctrl-d and ctrl-u for navigating preview up/down, ctrl-x,v,t bindings.
I'm not a big fan of how we are bending fzf to work with the custom sink calling the default sink this way. It feels very fragile. But i'm a total viml noob, so if anyone have a better solution i'm all ears.
function! FZFWithDevIcons()
let l:fzf_files_options = ' -m --bind ctrl-d:preview-page-down,ctrl-u:preview-page-up --preview "bat --color always --style numbers {2..}"'
function! s:files()
let l:files = split(system($FZF_DEFAULT_COMMAND), '\n')
return s:prepend_icon(l:files)
endfunction
function! s:prepend_icon(candidates)
let result = []
for candidate in a:candidates
let filename = fnamemodify(candidate, ':p:t')
let icon = WebDevIconsGetFileTypeSymbol(filename, isdirectory(filename))
call add(result, printf("%s %s", icon, candidate))
endfor
return result
endfunction
function! s:edit_file(items)
let items = a:items
let i = 1
let ln = len(items)
while i < ln
let item = items[i]
let parts = split(item, ' ')
let file_path = get(parts, 1, '')
let items[i] = file_path
let i += 1
endwhile
call s:Sink(items)
endfunction
let opts = fzf#wrap({})
let opts.source = <sid>files()
let s:Sink = opts['sink*']
let opts['sink*'] = function('s:edit_file')
let opts.options .= l:fzf_files_options
call fzf#run(opts)
endfunction
bump
The biggest challenge here is to have the prepend icon runs asynchronously. Otherwise the prepend would be a long wait, depends on how many files in your directory.
I customised @micke's snippet to use @coreyja's devicon-lookup which results in significantly faster response for me.
function! FZFWithDevIcons()
let l:fzf_files_options = ' -m --bind ctrl-d:preview-page-down,ctrl-u:preview-page-up --preview "bat --color always --style numbers {2..}"'
function! s:files()
let l:files = split(system($FZF_DEFAULT_COMMAND.'| devicon-lookup'), '\n')
return l:files
endfunction
function! s:edit_file(items)
let items = a:items
let i = 1
let ln = len(items)
while i < ln
let item = items[i]
let parts = split(item, ' ')
let file_path = get(parts, 1, '')
let items[i] = file_path
let i += 1
endwhile
call s:Sink(items)
endfunction
let opts = fzf#wrap({})
let opts.source = <sid>files()
let s:Sink = opts['sink*']
let opts['sink*'] = function('s:edit_file')
let opts.options .= l:fzf_files_options
call fzf#run(opts)
endfunction
Is there a way to make this work with open buffers as well?
@waigx could we maybe use this for async? https://github.com/tpope/vim-dispatch
@chris-fran - I am using external devicon-lookup pipeline as suggested above. Will take a look at vim-dispatch. It would be nice to have it async without external binary.
Is there a way to add devicons to :Ag search results (in fzf-vim plugin)? I am very satisfied with files searchinng with BAT but the last thing i wanna do is to search inside files with some BAT preview and devicons
@roszczypalam There is now π
I'm back in this thread to announce a vim
plugin that I put together again using my devicon-lookup
tool.
The new plugin is fzf.devicon.vim :tada:
It can be installed with your favorite vim package manager, though it does still depend on devicon-lookup
being installed externally.
This plugin is a fork of fzf.vim
and adds devicon support to each of the 'fileish' searches that it provided. Other fzf
usages that you want to add devicons to are also welcome, and PRs and Issues are encouraged!
While it is a fork, is made to be run side-by-side with fzf.vim
as the commands are all named differently.
One of the new things is actually the grep support. I added prefix
parsing into devicon-lookup
meaning it is now able of parsing grep
style results.
Besides the grep results, the functionality is pretty much the same as the other versions that have been shared here previously (so thanks to everyone for their contributions in this thread!). It supports all the the different ctrl
variants when opening files and should be feature compatible with fzf.vim
. Any missing features would be considered a bug (or an out of date fork) and issues and PRs would be appreciated!
Let me know what you guys think! Thanks!

Why not PR the main project?
@blayz3r I thought about it and might still. The main reason I didn't is that it doesn't actually integrate
into the fzf.vim
plugin. It just provides a replacement/clone for the commands it provides.
I decided that it would be easier to support a clone than it would be to support an insertion into the original code base, given the structure of the code and the nature of the problem at hand.
I wasn't sure this was in the spirit of this original repo, and I don't think maintaining a full fzf
plugin within the original repo would be desirable.
Another reason is that it requires an external tool to function (even besides fzf
itself).
But if @ryanoasis (and/or other maintainers) would like to include this in the original repo, I am MORE than happy to contribute it and help maintain it in this repo!

Makes sense I was imagining something like this https://github.com/kristijanhusak/defx-icons/blob/master/README.md. The plugins adds icons to Defx but doesn't force you to use new functions. But that is just my 2 cents.
hey all, sorry for the delay in chiming in. :wave:
lots of good solutions here, I am open to any PRs and also very cool with people just creating their own forks or projects (that's what's cool about OSS right?). That said I would love it was supported out of the box and it looks like others have posted possible solutions here already..
@ryanoasis Thanks for the reply!
So right now my solution (plus most of the others here that I am aware of) here don't really 'insert' icons into the original FZF
commands. Instead we just created new VIM commands from the underlying piece (which is kinda what fzf.vim
is on top of fzf
).
I decided to rename my commands so as to not 'shadow' the original ones.
If you (@ryanoasis) are ok with maintaining (with help of course π ) my implementation (potentially with a shim to not need devicon-lookup
ext tool) I would be happy to create a PR to this repo! I think it would basically be the same code I have, but instead of creating new command names it would just shadow the ones that already are exported by fzf.vim
While we don't yet have full support for devicons, we are working on a plugin that provides various resources for FZF.
It uses Vim script and ripgrep to apply the devicons. https://github.com/yuki-ycino/fzf-preview.vim
Any update?
Hey, itβs been 5 years people have been asking for this. Iβm pretty sure lots of people would contribute to provide all the patches listed above. Whatβs your take on this @ryanoasis?
FZF has a vim interface for fast file searching.
https://github.com/junegunn/fzf
Similar to ctrlp/unite. Would be interested in have some icons in there too :grin:
