Escaped " are not colored consistently

[SuperSandro2000]

If you decide to post your issue here, please include the relevant information:

• Your Vim version: VIM - Vi IMproved 8.2
• The name and version of any terminal emulator(s) or graphical environment(s) where you recreated the issue: Bash, Tmux, Windows Terminal
• Whether you are running gruvbox_256palette.sh: happens with and without it
• Information on any other relevant external color configuration, such as a terminal emulator theme: gruvbox
• A minimal .vimrc:

  source $VIMRUNTIME/defaults.vim
  set nocompatible
  call plug#begin('~/.vim/plugged')
  Plug 'gruvbox-community/gruvbox'
  call plug#end()

Both \" should have the same color.

Thank you for reporting.

Can't recreate this on the latest version of gruvbox and vim 8.2.2277 with many features enabled.

Please include the full output of vim --version. Please also confirm that the minimal .vimrc is complete. It doesn't include colorscheme gruvbox so I'm not sure if it's just missing the last line or something else.

This is possibly a builtin syntax bug, so if your version of 8.2 is older than mine you might want to try updating. If the problem persists, please use this binding and F10 to check the highlight group under the cursor:

map <F10> :echo "hi<" . synIDattr(synID(line("."),col("."),1),"name") . '> trans<'
\ . synIDattr(synID(line("."),col("."),0),"name") . "> lo<"
\ . synIDattr(synIDtrans(synID(line("."),col("."),1)),"name") . ">"<CR>

[SuperSandro2000]

Please include the full output of vim --version.

I just forgot to copy it after I commented out all the other things.

set nocompatible
call plug#begin('~/.vim/plugged')
Plug 'gruvbox-community/gruvbox'
cal plug#end()

This is possibly a builtin syntax bug, so if your version of 8.2 is older than mine you might want to try updating.

Also happens with vim from nixpkgs which is the newest version I have available.

VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Jan 01 1980 00:00:00)                                                                                                                          Included patches: 1-1522

The right i<shSpecialDQ> trans<shSpecialDQ> lo<GruvboxOrange> and the right escaped \" has hi<shDoubleQuote> trans<shDoubleQuote> lo<String>. This also happens with https://raw.githubusercontent.com/vim/vim/master/runtime/syntax/sh.vim.

Might be a bug in the highlighting of vim:

[rbong]

It does appear to be a vim syntax bug, not a gruvbox bug. Since shSpecialDQ and shDoubleQuote are different they could have different colors in any theme, not just gruvbox. There have been many runtime file updates since hat patch you have installed, it's tough to track down the exact fix since VIM doesn't list runtime file updates. Not sure what patch number that stable version you used is on but it is also likely older than what I have.

[SuperSandro2000]

I tried the latest from vim and their upstream and both still had the bug

[rbong]

I'm not sure but I think the stable release is on patch 0. If it still happens after patch 2277, which I'm on, you'll want to contact the maintainer of the sh.vim runtime file, who lists his contact info as Charles E. Campbell <NcampObell@SdrPchip.AorgM-NOSPAM> (VIM does not directly accept issues for runtime files). I have left his email formatted as it appears in the runtime file with spam prevention, it looks as if you'll want to remove the capital letters.
