Regex isn't working properly

frankjonen commented 1 year ago

Steps to reproduce

Example1: https://vim.fandom.com/wiki/Regex_lookahead_and_lookbehind

Put: The quick fox jumps over the lazy brown dog. in an empty buffer.
Search with /brown\( fox\)\e=

Brings up an error message instead of the word brown.

You can try the rest on that page. None work. Syntax files using /zs also have issues not selecting.

Expected behaviour

Should select the word brown in provided example.

Seems to work just fine for me? You didn't copy the example verbatim. It should be "quick brown fox" in the text, and you need to use \@=, \@!, or \ze, not \e or /zs. These details do matter a bit.

You can close it. I've been looking at it too long to see the issue. Turns out it wasn't Vim but some override that blocked the /zs /ze selections I needed. Took me some hours to find the lead.

Ah ok. Yeah we have all done that 😅.
