JS expressions function not working for me.

[sportniik]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with the newest version from GitHub (also it might have already been fixed in latest nightly build)
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions
• If you have a problem only with a particular file (or file type), use this form instead
• Windows 7, 8 and 8.1 are no longer supported. This is not a question about Windows 8.1 or older.

Operating System

Windows 10

Steps to reproduce

I used " segment.duration < 5 "

Expected behavior

All segments with duration less than 5 sec should be selected (as I understand).

Actual behavior

Nothing is selected, although I have few segments with less than 5 sec. The JS expression window does not close when I click "OK".

Share log from developer tools

No response

this is the nightly build, right? do you see any error message in developer tools javascript console? it works for me on macos but it could be an issue on windows. I saw this error message in an unrelated issue #2070 - and i have a feeling it's related:

index.html:1 Refused to execute script from 'file:///D:/Downloads/LosslessCut-win-x64%20(1)/resources/app.asar/out/renderer/assets/evalWorker-2659dcda.ts' because its MIME type ('video/vnd.dlna.mpeg-tts') is not executable.

I've managed to reproduce the problem on windows and I think I've found the issue vitejs/vite#11823

Thank you! Yes it works now. I have also tried it on 3.62.

I do have one question about this syntaxes that are available to click. "Segment label (exact)" and "Segment label (regexp)". The latter I do not understand.
For instance, if a segment label was "Video 3" and I input "/^Video 3/.test(segment.label)"; that segment would be selected. If I would only use "/^Video/.test(segment.label)", no number 3 added, it would not select anything.
So my question is what is the difference between (exact) and (regexp) syntax, cause the regexp looks to do same thing as exact?

Cause we can label segments like: Picnic - beginning. Picnic - cooking, Picnic - swimming ... Back at home - Dinner, Back at home - Piano, Back at home - Bedtime
So if I want to export only Picnic, I have to select all the segments with that label. If the video has only 6 segments that is no problem, but many have 50 segments or more. So having a syntax that would select segments that have word "Picnic" in their label would be very handy.

Thank you!

UPDATE:
"Segment label (regexp)" works (selecting only segments with word Picnic)!
First time I tried that syntax I only made 5 segments and they all had word Picnic on label. And using regexp gave no result, cause LLC did not select any segments. Than I added another segment, that was without Label, BAM, than it was working.

Hope it helps, if anyone has problems with this syntax.

Yes i purposefully made it so that if it's matching all segments, then it will not actually select anything, because that would not be very useful. I will make it so that it instead gives an error if all match
