Add ability to interpet WSL file paths

[CherryDT]

I'm using VSCode under Windows, but the actual code runs under Linux, hence the tests etc. also run under Linux (via WSL).

Unfortunately this means that the paths in lcov.info are like /mnt/c/Users/david/proj/myProject/myFile.js and your extension says "no coverage for file" for every file because it probably looks for C:\Users\david\proj\myProject\myFile.js instead.

Would it be possible to automatically convert the path (if it starts with /mnt) so that it can find the file?

[ryanluker]

@CherryDT hmm the option to use relativeSF paths may fix your issue. if you set coverage-gutters.altSfCompare to true, in your settings, and restart your vscode does that help any? I specifically use this option myself as I use WSL as well on my windows machine 😄 .

[CherryDT]

Hm, I just tried that but I got the same error.

Does the lcov.info file location have any effect on that? It is coverage/lcov.info for me.

[ryanluker]

hmm that file location looks fine to me... did you set the flag and restart vscode? sometimes the settings dont pickup til next IDE open. Worst case I will tinker on my machine to try to get the same error and get back to you sometime over the weekend.

[CherryDT]

Yes I did. Thanks for checking it for me! 👍

[ryanluker]

Hey @CherryDT I tinkered locally myself and couldn't replicate your same issue, except when I set altSfCompare to false then I would get the error...

Running coverage and starting vscode through bash on windows:

I could do more debugging if you provided me with more details like your windows version (creators on windows 10?), settings.json file, lcov.info file, vscode version and extension version. You should remove anything in those files that doesn't seem dev related, if you do choose to post them here, no personal info please. Hopefully we can get this sorted out!

@CherryDT any more insight into this issue?

VSCode version: 1.12.0-insider, commit 48ae6e30... Extension version: 0.5.0

[ryanluker]

@CherryDT Thanks for the extra info, sadly I do not have any progress on getting the extension to fail for me locally... The last thing we can try (and the most time consuming for you) is to have you checkout this project and run the extension in development mode with vscode (debug -> launch extension) and open the project you are trying to apply coverage for. This way you can add a few breakpoints like the ones in the screenshot below and we can really dig into why you are getting that message (of note are the config store values for altSFCompare and the array file paths). Let me know if you attempt this and get anything interesting or need assistance with the debugging.

[CherryDT]

Hello, I didn't have time to debug it yet. Now I wanted to take a look at it again, but now it suddenly appears to work just fine! Not sure what was changed.

[ryanluker]

Good to hear that the extension is working! by chance did you update to 0.6.0? I did tinker with the coverage bits alittle in this last release... Anyways I will close this ticket in a couple days unless something comes up.
