Hello developers, I believe I may have found a bug related to if/else and spell
checking with syntax regions and @Spell. Here's my .vimrc for testing:
========================================
set nocp
syntax on
function! TweakSyntax1()
set spell
if 1
syntax region test start=/</ end=/>/
else
exit
syntax region test start=/</ end=/>/ contains=@Spell
endif
hi link test comment
endfunction
function TweakSyntax2()
set spell
if 1
syntax region test start=/</ end=/>/
endif
hi link test comment
endfunction
========================================
Here's my test file:
========================================
<notaword> notaword
========================================
Here's a test script:
========================================
$ vim -u dot-vimrc test.txt
:call TweakSyntax1()
:syn
--- Syntax items ---
test xxx start=/</ end=/>/
links to Comment
Spell cluster=NONE
========================================
$ vim -u dot-vimrc test.txt
:call TweakSyntax2()
:syn
--- Syntax items ---
test xxx start=/</ end=/>/
links to Comment
========================================
If you open this file and call TweakSyntax1(): *neither* word is marked as
being spelled wrong. If you open this file and call TweakSyntax2(): *both*
words are marked as spelled wrong. The only difference is the existence of the
else clause, which isn't executed. I can't see a reason for it, what am I
missing?
My version is attached.
Thanks for looking!
