syntax highlighting not syncing

[y2kbugger]

sometimes when typing lists, the hyphens dont get highlighted until i scroll, or run :syntax sync fromstart if i run just :syntax sync I get the following response in the status bar and the highlighting does not update.

syncing starts 2147483647 lines before top line

That's strange, could be a vim bug, in the syntax file we already have syn sync fromstart which should do exactly what you do manually to fix the problem...

Maybe you have a personal configuration that disables syn sync fromstart in syntax files?

seems exactly like this guy. https://github.com/justinmk/vim-syntax-extra/issues/4 I wonder what be had wrong with the config. On Apr 20, 2015 4:35 AM, "Gabriele Lana" notifications@github.com wrote:

@y2kbugger ask him and report here so that the next one with the same issue could find out :smile:

I now notice that it only happens when editing at the end of the buffer, in fact if i move up and add a bullet to an earlier list, the highlight become correct in both places.

Maybe it's a real bug in syntax file, can you create a "small" example that reproduce the issue? If you can it will be great, but before I advise you to try to remove your configuration from the equation :wink:

looks like it is an actual bug somewhere, either with vim, or the vim-markdown. min.vimrc:

"setup for Vundle, the plugin manager
set nocompatible              " be iMproved, required
filetype off                  " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'gmarik/Vundle.vim'
Plugin 'gabrielelana/vim-markdown'
call vundle#end()
filetype plugin indent on    " required
"===============================================

" enable syntax highlighting
syntax enable

doesn't highlight even upon return to normal mode.

syntax sync yields this:

and syntax sync fromstart fixes this highlighting:

when adding something below, a new bullet gets highlighted correctly and instantly:

@y2kbugger could you try with the latest (715fa12ff651da838e58e7f88f18d47a1e611a7d) commit?

[y2kbugger]

almost, to reproduce from fresh doc:

1. add some bullets,
2. <Enter><Enter><Enter>
3. add a first bullet for a new list

There were also a few times that it glitched and didn't highlight that I couldn't reproduced in the time i spent, but iirc it happened when:

• moving indent back and forth
• adding a bullet at the very end of the document
• backspaces the first few letters (or maybe the space in front of the hyphen) of a list item and then typing something else

[gabrielelana]

@y2kbugger Thank you very much for your help, I'll look into that and I'll keep you posted

BTW markdown it's an ugly beast, all this is happening because detecting when a list item ends it's a nightmare :smile:

[gabrielelana]

Right now I'm unable to reproduce it so I'm going to close this issue
