Code Search with Regular Expressions

Problem description

Code Search feature limitation

Expected behavior

I tried using the regex pattern "(\w+)":\s*(\[[^\[\]]*\]) to capture information in a data file of my project but it did not work. It does work in my project but is having issues capturing everything I get when regex101: build, test, and debug regex tool and using the data.json file content.

Actual behavior

After regressing it a bit I was able to get the first part of "([a-zA-Z0-9])+":[ \t\n]+ to work in the Code Search feature proving that it is capturing with regex patterns. It stops capturing when I add \[. My hope is the Code Search would use the same engine as the browser (JS).

Steps to reproduce

Add Code Search window to project
Toggle regular expression button on
Paste in "([a-zA-Z0-9])+":[ \t\n]+ into the search window
Press enter
Paste in "([a-zA-Z0-9])+":[ \t\n]+\[ into the search window
Press enter
Compare results.

Replit Code Search does not work with RegEx expressions. If you want it to, please change this topic’s category to Feature Requests.


‘Replit Code Search does not work with RegEx…’ I am finding it does, but not to the extent of helping me debug my code. And it has an option toggle for it. ? The Feature Request was my first choice but after nudging it a bit, I was able to list the reproduce steps.

I have changed this to the Feature Request section, per instructed. :slight_smile:

I’m pretty sure it does work with regex? I could have sworn there is a toggle for it.

Yes, there is a regex toggle.
