Vim-devicons: icons in NERDtree can be only shown half.

[d0u9]

A picture is worth a thousand words:

There are dots shield half part of each icon in NERDtree.

Also, the space between icons and characters seems to wide...

PS: I use neovim and iTerm2 in OSX 10.11.2

[ryanoasis]

For the dots try:

autocmd FileType nerdtree setlocal nolist

For spacing you can adjust with:

let g:WebDevIconsNerdTreeAfterGlyphPadding = '  '

[d0u9]

@ryanoasis Works! Thank you!

[ryanoasis]

Hey no problem. Maybe I should consider setting this in the plugin by default

[code-geeker]

Hi ryanoasis ,
I'm in trouble with configuration.

Version:

It seems to occupy only one character bit.

PengJun

[ryanoasis]

I will try to test your vimrc, I think I found it on GitHub but could you post a link to the latest one?

In the meantime, are you using latest version of NerdTree and devicons?

Can you tell me which font you are using?

Is this macvim (gui) or vim on terminal?

[code-geeker]

Hi ryanoasis,
Thanks for your reply
I just pushed the latest .vimrc file

Yes,they are both latest version.

This is the font:

It is macvim(gui)

I suspect that the differing versions of macvim cause it.
It works well on version 7.4-77 but doesn't work on 7.4-101 (https://github.com/macvim-dev/macvim/releases/tag/snapshot-101)

Regards,
PengJun

[code-geeker]

BTW, It works well on vim on termina

[ryanoasis]

@code-geeker Sorry for the delayed response. I am looking into this issue.

BTW for the terminal vim you showed can you give the output of :version there as well?

[code-geeker]

@ryanoasis Thanks for your response.

[code-geeker]

It goes like this in the MacVim.

[ryanoasis]

Thanks. I will try to do some more digging

[lisposter]

same issue as @code-geeker

MacVim snapshot-104

set guifont=Meslo\ LG\ M\ Regular\ for\ Powerline\ Nerd\ Font\ Complete:h12

works well in terminal, even in neovim

[ryanoasis]

Sorry I still haven't had a chance to look into this, however @xusiyuan841028 has shared some info in the Gitter Chat that might be of some help to some of you. ¯_(ツ)_/¯

[lerrua]

Hey guys,

I'm using last macvim version (in homebrew) and last version for devicons and I have the same issue here:

An yes, I tried this code, but no success.

autocmd FileType nerdtree setlocal nolist
let g:WebDevIconsNerdTreeAfterGlyphPadding = '  '

The half icons bug happens with tabs also

[lerrua]

So, this can fix the issue set ambiwidth=double BUT breaks airline status line. Damm...

[ryanoasis]

The original issue from @d0u9 was actually a different problem (#84, #110) but we seem to now be using this issue in regards to a new (harder?) problem :stuck_out_tongue: ... so I am going to re-open this so there is less confusion and it's easier to find

@lerrua Hey yep sorry, still a serious issue.

Just wondering if anyone has been able to try @xusiyuan841028 suggested fix?

The cause of issue is that: https://github.com/macvim-dev/macvim/blob/0e954ac375d78d86cfd41377440c7f5977ae8924/src/screen.c#L8068-L8070

[xusiyuan841028]

@ryanoasis

My fix https://github.com/xusiyuan841028/macvim/commit/27bcfd27d6c3500b6ca27c7387a19b5a8306df17

You can install my edge version by:

brew install --HEAD xusiyuan841028/macvim/macvim

[ryanoasis]

@xusiyuan841028 Thanks I just have not been able to test it out (I don't have access to a mac at the moment).

I was hoping someone else could verify/try the suggested fix

[ryanoasis]

Seems like possibly due to change https://github.com/vim/vim/commit/cb0700844c1274fe8bc0ceaffaee0ad21c406f30 ?

I really need to test on an updated version of vim. Will try this weekend

[valerybugakov]

@xusiyuan841028 I've tried your patched version, but still have half icons bug.
What I did:

brew unlink macvim
brew install --HEAD xusiyuan841028/macvim/macvim
brew link --overwrite macvim

Is there anything else needed here?

[ryanoasis]

@valerybugakov Thanks for trying! I am not really sure if anything else is needed :worried:

[valerybugakov]

@ryanoasis oh, if there will be something I can do to help with this issue - tell me 😊
Awesome plugin and would be awesome to have it working properly on macvim!

[xusiyuan841028]

@valerybugakov I have tested the fixed macvim in another macbook, and it is fine. The version info is as following:

VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jun 23 2016 09:53:11)
MacOS X (unix) version
Included patches: 1-1952

I find the message Compiled by Homebrew, so I don't think you really use my patched macvim. I suggest you uninstall macvim, and re-install my patched version.

brew uninstall macvim
brew cleanup
brew install --force xusiyuan841028/macvim/macvim --HEAD

[valerybugakov]

@xusiyuan841028 thanks for the info, will try again in an hour 👍

[xusiyuan841028]

@valerybugakov please pay attention to compiled Jun 23 2016 09:53:11, I think the date should be the moment you install patched macvim. I will keep update my patched version until official version fixes the double-width char display issue. Everyone can use command brew uninstall macvim && brew install --force xusiyuan841028/macvim/macvim --HEAD to install the updated version.

[valerybugakov]

@xusiyuan841028 should my Included patches match yours?

$ mvim --version
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jun 28 2016 19:00:38)
MacOS X (unix) version
Included patches: 1-1965

I still have the same result 😥 After installation I got a warning from brew that macvim wasn't linked properly and I did brew link --overwrite macvim. Is this ok or it can be a source of an issue?

[valerybugakov]

@xusiyuan841028 Is there something specific that will identify your build for 100%? (that I've installed it correctly and test plugin with it)

[valerybugakov]

@xusiyuan841028 also a strange thing, after that ctrlp stopped working for vim and macvim

[xusiyuan841028]

@valerybugakov Could you give me your email? I wanna your compiled MacVim and send mine to you, in order to check whether the patched version is available. Or you can contact with me via my public email.

[valerybugakov]

@xusiyuan841028 sent you an email ([email protected])

[keenwon]

I solve this problem by this:

and my vimrc is: https://github.com/keenwon/vim

[xusiyuan841028]

@keenwon The font rendering becomes ugly！

[kristijanhusak]

I'm having the same issue:

OS: Xubuntu 16.04
Vim version: 8

In terminal Vim everything looks fine:

But in GVim it's cut in half:

I'm using Inconsolata font, specifically this one

[KabbAmine]

@kristijanhusak set ambiwidth=double should solve devicons problem, but all other unicode characters will look ugly (Try to write french characters: é,è...).

[kristijanhusak]

@KabbAmine that fixes the icons issue, but messes up my airline, and i have $ at end of each line.

[KabbAmine]

@kristijanhusak I know for airline, but the $ is from list/listchars options.

[seemethere]

Can confirm having this issue as well.

OS: macOS Sierra 10.12
Vim Version: MacVim VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Nov 22 2016 21:04:38)

[ryanoasis]

Thanks all for the helpful details. I know this is a pretty important and critical bug for using this plugin on MacVim.

I've been busy on Nerd Fonts but even so not sure even if there is something specific I could do to contribute to solving this. That being said I will continue to try to look for and accept ideas on how to resolve :smile:

[cmcginty]

I use the UbuntuMono font, and there are actually two versions that conflict in the package. If you only install the all the .*Mono.ttf fonts then there is no clipping. The standard fonts must have larger icons that clip, FWIW.

If there is a way to get the non-Mono fonts working that would be nice to see though. 👍 :shipit:

[xguerin]

@xusiyuan841028 I can attest that your patch is working except for double width characters in the tabline. Any hope to see your fix merged into MacVim ?

[dvakatsiienko]

@keenwon solution (disable Use Core Text renderer) fixed half-size devicons issue for me in MacVim, but without this option checked MacVim started working much slower =(

[felixsanz]

Happens on my Linux box too, using nerd fonts.

Btw the problem is this: tiagofumo/vim-nerdtree-syntax-highlight

Without color, icons display fine

[ActionScripted]

Been having the same issue with MacVim. While Preferences > Advanced > Use Core Text Renderer being unchecked fixed NERDTree it lead to everything else looking awful. So I've decided to leave the renderer on.

I added this to my .vimrc and things are now working in MacVim as expected...at least for icons. The problem now is that it seems to apply these settings to ALL buffers and not just the NERDTree buffers. Perhaps someone can clean/fix this up a bit?

    augroup devicons_nerdtree
        autocmd FileType nerdtree setlocal list
        autocmd FileType nerdtree setlocal listchars=space:.
        autocmd FileType nerdtree setlocal nolist
        autocmd FileType nerdtree setlocal ambiwidth=double
    augroup END

[xguerin]

The issue with MacVim is related to the CoreText engine.

I spent some time looking at the code. Currently, the glyph processor does not take into account double-width glyphs when painting the glyphs on the GC. And since the glyph processor does not use a proper path to layout the glyphs (I believe this is required to keep the column-based layout) the second half of the double-width glyph is overwritten.

I toyed with the CoreText API and it should be fairly doable to recognize double-width glyph before painting them and then instruct the CoreText engine to skip the next glyphs. If I get anywhere with this approach I'll let you know.

[felixsanz]

This is NOT related to only mac. All platforms suffer it.

[xguerin]

Mileage may vary. My point is that it's not a font-related issue but rather a tool-related one. Double-glyphs fonts work like a charm on macOS+Vim+iTerm2. They also work like a charm on *nix+Vim+libvte. However, they don't work with MacVim or GTKx renderers.

[felixsanz]

It doesn't work on Linux+Neovim+st terminal.

[Jeansen]

if you use another terminal, like rxvt, it works fine. At least for me.

[ryanoasis]

@ActionScripted That's a very good idea :smile:

 autocmd FileType nerdtree setlocal ambiwidth=double

however it looks like ambiwidth is not something that has a local value as it will always apply globally

[WillianGoncalves]

I hope it helps:
In my airline, after open GVIM, CTRL P and open a file, the icons appears like that:

Then, I switch to VISUAL mode and the icons appears correctly:

But if I open nerdtree, the icons back to initial state.

[ryanoasis]

@WillianGoncalves thanks for the info. Hmm my guess is that this would be the same affect as doing a redraw ?

[WillianGoncalves]

No, @ryanoasis. redraw didn't fix the icons. Instead, after get the full icons with VISUAL mode, redraw brought the problem back.
Besides that, I just realized that the method I posted works only for the first file.

[KabbAmine]

@ActionScripted ambiwidth and listchars are global options and can not be set locally, so a better approach is to call a function on all the filetypes where the needed options will be applied only when we have a nerdtree file.

An simple example here using a global variable to stock the default options:

augroup custom_nerdtree_options
    autocmd!
    autocmd FileType,WinEnter * :call <SID>SetNerdTreeOptions()
augroup END

function! s:SetNerdTreeOptions() abort
    if &l:filetype ==# 'nerdtree'
        let g:default_opts = {
                    \   'ambiwidth': &ambiwidth,
                    \   'listchars': &listchars,
                    \   'list'     : &l:list,
                    \ }
        setlocal ambiwidth=double listchars=space:. nolist
    else
        if exists('g:default_opts')
            let [&ambiwidth, &listchars, &l:list] = [
                        \   g:default_opts.ambiwidth,
                        \   g:default_opts.listchars,
                        \   g:default_opts.list
                        \ ]
            unlet g:default_opts
        endif
    endif
endfunction

[mlopes]

Having the same issue here, with neovim 0.2.0, and vim-devicons latest version. It doesn't look like it happens on every file though:

Note that the icon on stack.yml and on 30-icons.conf seems to be the same, but it's only cut in half in one of the instances.

Hope this helps.

EDIT: It looks like it's happening on the colourised ones only, maybe?

[MyGitTools]

hi, guys! as you can see, I met this problem when I tried to install vim-devicons, I just want to ask why the icons do not match the file type??????

[DemonCloud]

same issue here, Hi Friend!

[ryanoasis]

@MyGitTools That is strange. Which font are you using?

[MyGitTools]

thank you for replying my question

[jordwalke]

Summary of MacVim so far seems to be: Setting CoreText Renderer=off fixes the problem and tanks perf/quality.
Setting ambiwidth does seem to fix some of the icon drawing, and has some other remaining issues such as the following rendering of airline (latest MacVim, font=PragmataPro).

Notice the gap next to the arrow. That only shows up with ambiwidth=double.

[lucascaton]

Still happening here:

• vim-devicons 8ee4c8cdef4f6ea0f27b341ac077c303d0e57a90 (May 19 20:01:06 2018 -0400)
• VIM 8.0 (2016 Sep 12, compiled Mar 24 2018 08:30:22)
• MacVim snapshot 146
• macOS High Sierra 10.13.4 (17E202)

[jordwalke]

@lucascaton The latest macVim should have my pull request which fixes it.

[lucascaton]

Awesome, thanks @jordwalke!

[IsOverThere]

It looks this issue only happens when gtk version is 2.0.
With GTK3.0 the icon is fine. Well, terrible lag issue on gvim with GTK3.0, cannot use that....

[jadero]

I am facing the problem with the cut-off devicons under Windows 10 too with GVim 8.1. Patching the font with option --mono mitigates this but the icons are smaller in dimension. The problem also shows up in Startify and Airline plugins.

[jordwalke]

I have suggested to @fabrizioschiavi (creator of Pragamata Pro font), that for maximum compatibility, NERD fonts (and other wide glyphs) be implemented as ligatures. So what that means is that everything can remain monospaced, but then if you include a vim-devicon character followed by a space, the font would render it as the nerd icon. This should avoid the most amount of rendering bugs and work in the most editors - as long as they support ligatures (which they are increasingly)

[ChrisMGeo]

I'm in Linux, and I can confirm for myself that its something related to tiagofumo/vim-nerdtree-syntax-highlight. My guess is that there is some error that makes the glyph only take one character, regardless of the padding, but I might be completely wrong.

[bellini666]

I have this problem with using Inconsolata font.

I have the same font on both my terminal and gvim. The terminal vim display icons fine, gvim cuts them in half.

[GioF]

Same problem using Inconsolata font, too.
same font on both st and neovim.

[TheMasteredPanda]

I had this very issue with neovim v0.4.3, with the font Noto Mono Nerd Font.

I discovered it was in fact the plugin tiagofumo/vim-nerdtree-syntax-highlight that caused the issue. Not all icons are displayed as expected.

@TheMasteredPanda I don't have that plugin and I also have the issue, not only in nerdtree which I barely use but also on ctrlpvim/ctrlp.vim
