Check status of Julia installation and environment

Description

Check if Julia can be found and if the Julia environment for sdbuildR has been instantiated. Note that this does not mean a Julia session has been started, merely whether it could be. For more guidance, please see this vignette.

Usage

julia_status(verbose = TRUE)

Arguments

verbose

If TRUE, print detailed status information. Defaults to TRUE.

Value

A list with components:

julia_found	Logical. TRUE if Julia installation found.
julia_version	Character. Julia version string, or "" if not found.
env_exists	Logical. TRUE if Project.toml exists in sdbuildR package, which specifies the Julia packages and versions needed to instantiate the Julia environment for sdbuildR.
env_instantiated	Logical. TRUE if Manifest.toml exists (i.e., Julia environment was instantiated).
status	Character. Overall status: "julia_not_installed", "julia_needs_update", "sdbuildR_needs_reinstall", "install_julia_env", "ready", or "unknown".

What to Do Next

Based on the 'status' value:

"julia_not_installed"

Install Julia from https://julialang.org/install/

"julia_needs_update"

Update Julia to >= version 1.10

"install_julia_env"

Run install_julia_env()

"ready"

Run use_julia() to start a session

Examples

status <- julia_status()
print(status)
