Support for source markers in Positron?

[etiennebacher]

I have a package where I use RStudio's source markers using rstudioapi::callFun("sourceMarkers", ...). Since this feature is not available in VS Code for instance, I put it behind rstudioapi::isAvailable(). However, it turns out that rstudioapi::isAvailable() returns TRUE in Positron, but source markers are not supported.

Will they be supported in the future? Alternatively, do I have a way to detect that the user is using Positron?

rstudioapi::isAvailable()
#> TRUE
rstudioapi::callFun("sourceMarkers")
#> Error:
#> ! Function sourceMarkers not found in RStudio

I will open a new feature request with this for us to track and prioritize a fix.

In the meantime, you can can distinguish between Positron and RStudio via the environment variables "POSITRON" and "RSTUDIO", like this:
