Using a regex to mark a particular form as accepted spelling?

[Tim Chase]

Taking some notes, I have a lot of page-references of the form "p12",
"p35-36", etc. With 'spell' set, it highlights them as misspelled
words. However, I can formulate a regex that would identify these:

/\<p\d\+\%(-\d\+\)\=\>/

Is there a way to convey this information to vim so that they get
ignored for spellcheck purposes?

I know there's some highlight-group aspect that might be usable,

contains=@NoSpell

as detailed at `:help spell-syntax`, so I think I have the relevant
pieces, but am just failing to put them together in the right way
(writing syntax files is not my forte)

What do I need to do to assemble these so spell-checking ignores my
page-number ranges?

Thanks,

Try

   

   syntax match MyPages /\<p\d\+\%(-\d\+\)\=\>/ contains=@NoSpell

This would work for an existing buffer, to (auto)apply it, let's assume you're in filetype=text

augroup NoSpellPages
    au!
    au Filetype text syntax match MyPages /\<p\d\+\%(-\d\+\)\=\>/ contains=@NoSpell
augroup END

My spell-highlight is now much more useful because it's no longer so
visually cluttered. Thanks so much!
