How to have the spell checker ignoring URLs and acronyms

[Walter Cazzola]

Dear Vim Experts,
bored to have acronyms and URLs marked as errors in my LaTeX files I have
looked for a solution. Here

http://www.panozzaj.com/blog/2016/03/21/ignore-urls-and-acroynms-while-spell-checking-vim/

Suggests to add

syn match UrlNoSpell '\w\+:\/\/[^[:space:]]\+' contains=@NoSpell
syn match AcronymNoSpell '\<\(\u\|\d\)\{3,}s\?\>' contains=@NoSpell

in ~/.vim/after/tex.vim but it doesn't seem to work.

:scriptnames lists the file correctly loaded

226: /usr/share/vim/vim82/ftplugin/tex.vim
227: /usr/share/vim/vim82/ftplugin/plaintex.vim
228: /usr/share/vim/vim82/ftplugin/initex.vim
229: ~/.vim/bundle/vim-polyglot/after/ftplugin/tex.vim
230: /usr/share/vim/vim82/syntax/tex.vim
231: ~/.vim/bundle/vim-polyglot/after/syntax/tex.vim
232: ~/.vim/after/syntax/tex.vim

But it seems ignored and all my acronyms are still marked as errors.

I've already commented out all the plugins and still they are ignored.

What am I doing wrong?

I'm using Vim 8.2 on a linux box, Vundle is my plugin manager and I've
vim-latex installed.

Any help is welcome. Thank you.

Walter

PS. Note that to add all the acronyms to the list of known words is not a
feasible option.

I suspect that you need to get your matches contained in various groups. For a start, consider also trying (in ~/.vim/after/tex.vim)

syn cluster texFoldGroup add=UrlNoSpell,AcronymNoSpell

You didn't provide any examples, so the above is a guess.

Hi,
thanks for the reply

This mostly did the trick. It now works in some cases but not everywhere, see
the minimal example below.

You are right, this is a MWE

\documentclass[a4paper]{article}
\begin{document}
SUT (SUT) [SUT] {SUT} SUT,
$SUT$
\section{A section about SUT.}
\begin{itemize}
\item SUT
\end{itemize}
\begin{figure}\caption{whatever SUT is}\end{figure}

ftp://erlang.org/doc/man/erl_tracer.html
\url{ftp://erlang.org/doc/man/erl_tracer.html}
\end{document}

in this case, the acronym SUT and the URL are correctly ignored in paragraphs
(also when followed by punctuation symbols) but not when in a command as
\section, \url or \caption. What I see is in the attached pic.

Currently, my .vim/after/syntax/tex.vim contains:

syn cluster texFoldGroup add=UrlNoSpell,AcronymNoSpell

syn match UrlNoSpell '\w\+:\/\/[^[:space:]]\+' contains=@NoSpell
syn match AcronymNoSpell '\<\(\u\|\d\)\{3,}s\?\>' contains=@NoSpell

Probably, there will be another group to add these patterns. Where can I read
all the possible groups?

Thank you
Walter

Well, all the groups are explicitly laid out in syntax/tex.vim, albeit embedded with the rest of the syntax highlighting. What you might consider doing is using hilinks.vim (http://www.drchip.org/astronaut/vim/index.html#HILINKS, :HLT!) which will then tell you what syntax and highlighting is currently in-use under your cursor. Using your example I typed :HLT!, placed the cursor on the f in ftp:... and noted that the syntax stack has texDocZone->texSectionZone -- so you'll want to use

syn cluster texSectionZone add=UrlNoSpell,AcronymNoSpell

to your after/syntax/tex.vim file.

Hi,
thank you for the reply. Unfortunately, your suggestion didn't solve the
issue.

I have installed your HILINKS and added any name coming out from it and now my

.vim/after/syntax/tex.vim

is

syn cluster texDocZone add=UrlNoSpell,AcronymNoSpell
syn cluster texFoldGroup add=UrlNoSpell,AcronymNoSpell
syn cluster texMatcher add=UrlNoSpell,AcronymNoSpell
syn cluster texParen add=UrlNoSpell,AcronymNoSpell
syn cluster texSectionZone add=UrlNoSpell,AcronymNoSpell
syn cluster texSubSectionZone add=UrlNoSpell,AcronymNoSpell
syn cluster texSubSubSectionZone add=UrlNoSpell,AcronymNoSpell

syn match UrlNoSpell '\w\+:\/\/[^[:space:]]\+' contains=@NoSpell
syn match AcronymNoSpell '\<\(\u\|\d\)\{3,}s\?\>' contains=@NoSpell

but still no lucky. Still acronyms and URLs aren't recognized when inside
parenthesis (both normal parenthesis and those introduced by LaTeX commands)

In the attached movie you have the results from HLK! on the MWE.

What am I doing wrong?
