Does this work with Codespaces? As far as I can tell, it instructs the host OS to open the folder, and I'm not sure that works properly when the machine that has the directory is hosted in the cloud somewhere.

[aeisenberg]

Good question. I have not tried this on codespaces. I'm not even sure what the expected behaviour should be. Probably the best result would be to disable the command if the file system is remote.

It looks like there is already a precedent for that with the Reveal in Finder command (and the equivalent in linux/windows) not being available in codespaces.

Added this line and verified on codespaces that the option does not show:

In that case, I do not see how this PR "Fixes #1174 (comment)", as that comment pertains directly to the use of Codespaces.

Hmmm...right. At least now, a broken command won't be visible in codespaces. Also, this logs will stick around after restarts. All the data is stored in the workspace storage folder. You need to ensure that the workspace remains the same across restarts.

This command is quite useful in non-remote situations and is something I wanted to implement anyway.

I will take a look at a way to copy the path to the clipboard later.

Query logs will be saved in subdirectories of /home/codespace/.vscode-remote/data/User/globalStorage/github.vscode-codeql/queries. One directory for each query in a file called query.log.
