Description tbartdev 2010-03-30 13:58:52 UTC

There is a syntax highlighting bug in vim when using only one escaped double quote within double square brackets and the regex match operator

Reproducible: Always

Steps to Reproduce:
1. open (g)vim
2. put this into a document:
#!/bin/bash
[[ $a =~ \" ]] && echo something
3. Possibly save (and reopen) to activate bash syntax highlighting

Actual Results:  
Everything after the escaped double quote is treated as if after an UNescaped double quote

Expected Results:  
Escaped quote should be handled as such and not be treated as a regular double quote

Error seems to be in /usr/share/vim/vim72/syntax/sh.vim
but I neither have a clue of vim syntax highlighting language nor whether this is a Gentoo bug or a vim bug...

Confirmed on Gentoo x86 with app-editors/vim-7.2.303 and app-editors/vim-core-7.2.303. It also happens on a Debian system with version 7.1.314 of vim.

I just tested this with the latest vim (7.3.322) and this has been fixed sometime in the intervening years.

Confirmed with vim 7.3.322 emerged with the ~x86 keyword for the test.
