vim folding messes up syntax highlighting

Question

I'm using vim for LaTeX and I'm using latex-suite. It gives me nice syntax highlighting and folding, but in large files syntax highlighting gets "confused". If I open all folds, the syntax highlighting turns OK. I would like it to "just work" all the time though.

I seem to recall an option that would increase the number of lines that is used as basis for determining syntax highlighting but I cant find it.

Answer 1

I don't edit LaTeX, but perhaps you want ":syn sync fromstart"? Just be warned that this can significantly slow down Vim since it forces Vim to do syntax highlighting parsing for the whole file rather than a section of the file. See ::help :syn-sync".

Answer 2

• Ctrl+L in normal mode forces a redraw and often fixes syntax colour problems.
• zRzMzx (i.e., expand all folds, contract all folds, fold to show current line) sometimes fixes syntax highlighting problems related to folds
