What for?

When editing files with certain code blocks,it's nice to have them highlighted properly.

How to use it?

:[range]RegionSyntax filetype highlight the selected block. :RegionSyntaxToggle enable/disable this plugin. Or you can specify new rules for dynamic syntax highlighting with the global variable g:regionsyntax_map.

Say you would like to highlight this

$$
...
$$

in html as tex,you could use the following config.

let g:regionsyntax_map = {
            \ 'html':
            \ [{
            \   'start' : '\m^[ \t]*\$\$[ \t]*$',
            \   'ft' : 'tex',
            \   'end' : '^[ \t]*\$\$[ \t]*$'
            \ }]}

You could set a list of rules for a certain local filetype. for more info, please view the doc
