Detect external solver software and dependencies

Read-only detectors that report whether each external backend energyRt can use is installed and runnable. en_check_dependencies() runs all of them and prints a status table; the individual en_check_*() functions probe a single backend and return a one-row tibble (component, required, found, version, path, note). None of these functions install anything — see en_install_deps().

Each detector honours the path configured via the corresponding set_*_path() (e.g. set_julia_path()) and falls back to the system PATH.

Usage

en_check_glpk()

en_check_julia()

en_check_python()

en_check_pyomo()

en_check_gams()

en_check_gdx()

en_check_julia_pkgs(pkgs = c("JuMP", "HiGHS"))

en_check_dependencies(solver_pkgs = FALSE)

Arguments

pkgs

character vector of Julia package names to verify.

solver_pkgs

verify Julia solver packages too (slower; starts Julia).

Value

A one-row (en_check_*) or multi-row (en_check_dependencies) tibble, returned invisibly for en_check_dependencies() which also prints a table.
