◆ IsConverterInstalled()

bool SMESH_Meshio::IsConverterInstalled ( SMESHIOConverter::ExternalConverter converter = SMESHIOConverter::ExternalConverter::Gmsh )

static

Check if a given converter library is installed and allowed for use.

This function performs two verifications:

Environment check:
- Reads the corresponding environment variable (e.g. GMSH_VERSION, MESHIO_VERSION).
- If the variable is set to 0 or invalid, the converter is considered disabled.
Executable check:
- Attempts to start the corresponding executable with "--version" (or "meshio-info --version" for legacy MeshIo).
- If the process starts and exits normally, the converter is considered available in PATH.

A converter is considered installed only if both checks succeed.

Parameters

converter The converter to check (Gmsh, MeshIo).
