RegEx - find all occurrences of a word and exclude certain words that contain it

Question

searching all over couldn't find a solution and also am breaking my head with this for a while already.

I want to search for all occurrences (words not sentences containing) of word end but exclude certain words from being found - that I want to specify myself.

For example, I am interested in all possible combinations of (should match):

• end
• ended
• date-end
• hasEnded
• end_date

but I want to exclude all these words for example (should not match):

• render
• appendTo
• extend
• renderGrid

while not selecting the whole lines, only the matching words.

The closest I could get is this regex: (?!extend|appendTo|render|renderGrid)(\b.*end.*\b) but this selects the whole lines and more-over doesn't work in Search in files in IntelliJ IDEs which is frustrating.

Anybody willing to improve and make it working in Search in files in IDEs?

Answer 1

You could match 0+ times a non whitespace char \S* at both ends or use a character class [\w-]* and specify what you would allow to match.

You might omit the capturing group and get the matches only.

(?!extend|append|render|renderGrid)\b\S*end\S*\b
