Code between { } of a map/grep doesn't get hilighted

[ghost]

Anything between map/grep's curly brackets is not properly hilighted (no colour at all).
E.g.: grep { /$this_does_not_get_hilighted/i } @array;

@emanrsu thanks for this report.
I think this was a compromise, or you may call it a workaround, I did long time ago solving some problems with double-included perl.vim syntax file.

At the moment you have to choose between highlighted DATA content for Mojolicious apps and highlighted grep/map blocks.

You may find the following line in your .vimrc:

let mojo_highlight_data = 1 

And remove it. DATA section won't be highlighted anymore, but grep/map blocks would.

If this really annoys you, feel free to investigate and fix it.
Otherwise I'll take look at it closer when I have some free time.
Hovewer, it doesn't likely to happen in this century.

Luck

This code in test.hrml.ep not proper highlighted too:

% if(1) {
 <tr class="<%= join ' ', @class %>" >
            <td>
% }

@rshadow that's not related to #7
Feel free to open a separate issue (or I'll do it later myself)

Thank you

1. Are you using mojo.vim from trunk?
2. Are you using vim-solarized color scheme? If yes, please try with latest solarized.
   Thanks

I experience a seemingly related problem (and I assume so because removing the mojo_highlight_data fixes it). The problem is seen in pure perl code (i.e. before the __DATA__ section, not in a template) especially around constructs like %{ $href_or_undef || {} }. In this case the last closing curly brace seems to be ignored for highlighting purposes; it isn't highlighted itself and the highlighter seems to have missed that the block has ended. The problem persists for the remainder of the file.

As seen in the picture, the first method is fine, the second has the problem curly braces (twice actually though once is enough), and the third method continues with broken highlighting.

I did some tinkering about with this last night and this morning - I managed to generate the following patch to solve the issue on a stupid little Mojolicious::Lite example:

Please give this a try and let me know if it works for other, larger codebases!

I think the problem was because all the action is happening in an after/ file, which then loads a syntax file that reloads syntax/perl.vim, and Vim gets super confused.
