spell.c: apostrophe as word boundary (for french)

[thjbdvlt]

hello!

i've searched for a way to tell the neovim spell to process apostrophes just like spaces (as word boundaries), but i couldn't find any way to do it. so i'm trying to modify the spell.c file but i cannot manage to make it work. has someone any idea which part i should modify?

because in french, it's how apostrophe is used. for example, the word 'arriver' (to come) (or any verb beginning with a voyel) can be used like this: "j'arrive" (i come), "n'arriver" (not to come), "t'arriver" (to come to you), "m'arriver" (to come to me), "d'arriver" (to come), "qu'arriver" (just to come), and so on. the pattern word + apostrophe + word is very very very common (i'd say 90% of the sentences i write). and i don't want to add theses patterns in my spell files, because it would massively increase their size (and because it's against the french grammar). in the other hand, there is only one word containing an apostrophe, it's "aujourd'hui" (and its actually many words joined into one).

of course, it's only for my personal use, i don't know very well the syntax of other natural languages so i don't know if it's a french-only case (but if it's usefull, i can try to do something).

what spell do you use? plugin or native spell? what exacly your problem? is it about false positive spell to detect your personal word? so i can try to reproduct in my machine.

FYI:
if you just want to detect apostrophe like space you can use isfname:

	setlocal isfname+=32,[,',?,`,;,&  "all char as literal
	setlocal isfname-=#	          "all char as space(non literal)
	setlocal path+=$WIKI_DIR/         "target dir
	setlocal suffixesadd+=.adoc       "target file extension

:set isfname to check default isfname

thank's for your answer! :)
i use the native neovim spell, and my problem is wrong negatives. for example i've added the word auteurice. and l'auteurice, d'auteurice, qu'auteurice or presqu'auteurice are considered wrong (hence underlined). but there is no reason for that because in a form like d'auteurice there are two words, not one. it should be the same as d.auteurice. for verbs it becomes unmanageable because for verbs there is like 17 forms like this.

i've tried to set the isfname, but it does not change anything, words are still underlined as wrong.

as far as i know native spellcheck

Vim only checks words for spelling, there is no grammar check.

so what we can do are add your personal grammer with zg it will save word undercusor to your personal grammer in $HOME/.config/spell/fr.add
hope it will satified you.

i would like to avoid zg every combination, as the number is really huge (it's why i want neovim not to consider apostophe as a word character). but it seems i have to rewrite .aff and .dic files and recompile with mkspell.

if anyone someday looks for the same thing: i wrote an alternative spell file (that doesnt consider apostrophe/hyphen as word character) and i put i there. so i close the discussion :)
