pathmap and jump to definition

[joprice]

I have a use case where I want to use CallerFilePath along with PathMap to generate short paths for debug information, as described in the first answer in this stackoverflow question https://stackoverflow.com/questions/65935784/is-it-possible-to-remove-the-full-paths-from-net-assemblies-created-with-dotnet. However, it seems the path map breaks fsautocomplete's jump to definition functionality. It reports an error that a path like /_/Auth.fs is not found. Is there a way to configure fsautocomplete to either ignore the setting or to map it back to the local path? Or is it recommended that I make these settings conditional, only applying to a release build, where dev tooling wouldn't apply?

My initial workaround idea would be to add a condition that is Condition=“‘$(DesignTimeBuild)’ != ‘true’”.

But @baronfel would have deeper understanding and if there’s something we need to fix in ProjInfo.

We probably need to do what we do for source link (which also uses deterministic paths) but in a more generalized manner. Each project has a target that you can call to get PathMap information, and we'd use that information to construct the real root path whenever we were dealing with a deterministic path. @TheAngryByrd it's almost like we should be thinking of paths as a tri-state union of

• Deterministic
• Relative
• Absolute

(At least for go to def)
