Tex icon affects filename

[mrossinek]

I was unsure whether to file this issue here or at https://github.com/kyazdani42/nvim-web-devicons so I am going to tag @kyazdani42

Today I noticed the following bug:

On the left you can see a dirvish buffer of the contents as listed on the right.

On line 6 you can see that the filename of the tex file is printed in reverse! I have no idea what could cause this but without the devicons it obviously does not happend.

I use this to display the icons:

call dirvish#add_icon_fn({p -> luaeval("require('nvim-web-devicons').get_icon(vim.fn.fnamemodify('" .. p .. "', ':e')) or ' '")})

well i don't think this should be related to icons. Could you reproduce with a super minimal vimrc ? like only dirvish and web devicons ?

On my system, starting nvim -u NONE and then sourcing the following file, seems to do the trick at reproducing the issue:

packadd vim-dirvish
packadd nvim-web-devicons
call dirvish#add_icon_fn({p -> luaeval("require('nvim-web-devicons').get_icon(vim.fn.fnamemodify('" .. p .. "', ':e')) or ' '")})

Here is the output of :scriptnames after running the above and calling :e .:

  1: ~/tmp/init.vim   <- this is the file above
  2: ~/dotfiles/nvim/.config/nvim/pack/minpac/start/vim-dirvish/plugin/dirvish.vim
  3: ~/dotfiles/nvim/.config/nvim/pack/minpac/start/nvim-web-devicons/plugin/nvim-web-devicons.vim
  4: ~/dotfiles/nvim/.config/nvim/pack/minpac/start/vim-dirvish/autoload/dirvish.vim
  5: ~/dotfiles/nvim/.config/nvim/pack/minpac/start/vim-dirvish/ftplugin/dirvish.vim

I don't think this issue can come from nvim-web-devicons, which only returns an icon and a highlight group. It doesn't operator on text. Dirvish must do something weird with the result.

[kyazdani42]

:lua print(require'nvim-web-devicons'.get_icon('tex')..' test.tex') doesn't produce any weird stuff. This issue is dirvish related imo.

:lua print(require'nvim-web-devicons'.get_icon('tex')..' test.tex') doesn't produce any weird stuff. This issue is dirvish related imo.

Actually, I observe the same strange behavior when not placing the space between the icon and the text. I.e.:

lua print(require('nvim-web-devicons').get_icon('tex')..'test.tex')

Gives: xet.tsetﭨ

PS: Sorry for the long delay, I only just found time to look into this again.

[mrossinek]

Try for example opening the following file:

Text before TeX character:
test ﭨ

Text after TeX character (with a separating space):
ﭨ test

Text after TeX character (withOUT a separating space):
ﭨtest

Here is a screenshot of the results:

The editors are:

• Top left: nvim test.tex
• Bottom left: nvim --noplugin --clean test.tex
• Top right: \vim test.tex
• Bottom right: \vim --noplugin --clean test.tex

The issue does not appear in alacritty so I am starting to believe it lies with kitty. I will close this here and take my issue there..
