Starting Julia with a specific project environment

[msainsburydale]

First, thanks very much for the package, it works very well!

Is it possible to begin the Julia session from R with a specific project environment (i.e., a project encapsulated in Project.toml and Manifest.toml files)? Usually when working with Julia in terminal, I would start it with julia --project=. to start Julia with the environment of the working directory, but I'm not sure how to do this with JuliaConnectoR.

Thanks in advance!

Thank you, it is great to hear that you find the package useful!

Indeed there is a feature that allows this. You find the documentation of the feature in the package documentation in the section "EnvVars-JuliaConnectoR":

You can achieve your goal by setting the environment variable JULIACONNECTOR_JULIAOPTS. Citation from the documentation:

JULIACONNECTOR_JULIAOPTS: Set start-up options for Julia. As an example, consider specifying the project environment and enabling code coverage when starting Julia. This can be achieved by setting the environment variable to "--project=/path/to/project --code-coverage".

So for your example, you can set

Sys.setenv("JULIACONNECTOR_JULIAOPTS" = "--project=/path/to/project")

before connecting to Julia. Then the project will be used.
