I want to match all paths that include the keyword build unless they also contain .html
Here is a working regex that uses negative lookahead: https://regexr.com/4msck
I am using regex for path matching in unison which does not support negative lookahead. How can I replicate the functionality of the above regex without negative lookahead?
It is possible, but the resulting regex is pretty poor in terms of readability and maintainability.
^(?:[^\.\n]|\.(?:$|[^h\n]|h(?:$|[^t\n]|t(?:$|[^m\n]|m(?:$|[^l\n])))))*build(?:[^\.\n]|\.(?:$|[^h\n]|h(?:$|[^t\n]|t(?:$|[^m\n]|m(?:$|[^l\n])))))*$
Explanation:
^ - start of string/line(?:[^\.\n]|\.(?:$|[^h\n]|h(?:$|[^t\n]|t(?:$|[^m\n]|m(?:$|[^l\n])))))* - matches anything that does not contain .htmlbuild - literally that string(?:[^\.\n]|\.(?:$|[^h\n]|h(?:$|[^t\n]|t(?:$|[^m\n]|m(?:$|[^l\n])))))* - same as before$ - end of string/line
