enable code coverage from C-embedded Julia

[gbambini]

Currently, as far as I understand, the only way to activate code coverage in Julia is via the --code-coverage command-line flag. However, when embedding Julia through the C API using functions like jl_init(), there is no documented or supported way to pass such flags.

As a result, it appears to be impossible to enable code coverage when Julia is embedded from a C program. This limitation makes it difficult to track test coverage in environments where Julia is integrated as a component of a larger native application.

It would be extremely helpful to:

Allow passing startup arguments (like --code-coverage=user) programmatically via jl_init() or a similar API.

Or alternatively, provide a global programmatic interface or configuration file to enable coverage in embedded contexts.

This would greatly enhance the tooling and testing capabilities for projects embedding Julia.

Thanks for considering this!
