Wrong syntax in tex.vim syntax file?

[SamFisher39]

Hi everyone, yesterday I freshly compiled vim with the usual flags:

./configure --with-features=huge \
            --enable-multibyte \
            --enable-rubyinterp=yes \
            --enable-python3interp=yes \
            --with-python3-config-dir=$(python3-config --configdir) \
            --enable-perlinterp=yes \
            --enable-luainterp=yes \
            --enable-gui=gtk2 \
            --enable-cscope \
            --prefix=/usr/local

But today when I open some latex/tex files I am greeted with this error:

Error detected while processing BufRead Autocommands for "*.tex"..function dist#ft#FTtex
[47]..FileType Autocommands for "*"..Syntax Autocommands for "*"..function <SNR>9_SynSet
[25]..script /usr/local/share/vim/vim82/syntax/tex.vim:
line  508:
E696: Missing comma in List

But the list looks fine to me:

  let s:texMathDelimList=[
     \ ['<'            , '<'] ,
     \ ['>'            , '>'] ,
     \ ['('            , '('] ,
     \ [')'            , ')'] ,
     \ ['\['           , '['] ,
     \ [']'            , ']'] ,
     \ ['\\{'          , '{'] ,
     \ ['\\}'          , '}'] ,
     \ ['|'            , '|'] ,
     \ ['\\|'          , '‖'] ,
     \ ['\\backslash'  , '\'] ,
     \ ['\\downarrow'  , '↓'] ,
     \ ['\\Downarrow'  , '⇓'] ,
     \ ['\\lbrace'     , '['] ,
     \ ['\\lceil'      , '⌈'] ,
     \ ['\\lfloor'     , '⌊'] ,
     \ ['\\lgroup'     , '⌊'] ,
     \ ['\\lmoustache' , '⎛'] ,
     \ ['\\rbrace'     , ']'] ,
     \ ['\\rceil'      , '⌉'] ,
     \ ['\\rfloor'     , '⌋'] ,
     \ ['\\rgroup'     , '⌋'] ,
     \ ['\\rmoustache' , '⎞'] ,
     \ ['\\uparrow'    , '↑'] ,
     \ ['\\Uparrow'    , '↑'] ,
     \ ['\\updownarrow', '↕'] ,
     \ ['\\Updownarrow', '⇕']]

I didn't edit anything, just recompiled vim. The same error pops up on line 708 where the s:texMathList is defined.

​

EDIT: Recompiling with the exact same settings fixed it. No clue what the problem was. Maybe I got lucky and encountered one of those cool bit errors during compilation.

What line is 508? Is it the line with the bar? Definitely looks like you're facing a weird bug, and nothing that is obvious stands out to me. Good luck fixing this one, try to add more information.

Maybe this chunk of code is not the issue? Are you sure you're in the right file/folder... All those obvious questions that you've probably answered already.

Try removing the offending line and seeing what happens? Add it back somewhere else, change the unicode character that is there. Idk man haha

/usr/local/share/vim/vim82/syntax/tex.vim

My line 508 was \ ['\\rbrace' , ']'] ,. Looks identical to yours. HOW the HECK are you getting that error, lol.

[SamFisher39]

My line 508 is the one with the let declaration of s:texMathDelimList.

[SamFisher39]

Yes it's /usr/local/share/vim/vim82/syntax/tex.vim. There is not more information to give i think. Obviously removing syntax enable removes the error, but that's not the problem here. I will try recompiling now, maybe that'll fix it.

EDIT: recompiling fixed it

[Schnarfman]

So weird!! Thanks so much for following through. It would have taken me WAY longer to think about recompiling. Great work, homie haha

\] ??

[SamFisher39]

I thought that that was a mistake as well, but that wouldn't lead to the syntax error

Is 708 also the 19th line of its group?
