◆ GetVersionedEnvVarValue()

std::optional< wxString > ENV_VAR::GetVersionedEnvVarValue	(	const std::map< wxString, ENV_VAR_ITEM > &	aMap,
		const wxString &	aBaseName
	)

Attempt to retrieve the value of a versioned environment variable, such as KICAD8_TEMPLATE_DIR.

If this value exists in the map, it will be returned. If not, the map will be searched for keys matching KICAD*_<aBaseName>, and the first match's value will be returned. If there are no matches, std::nullopt will be returned.

Parameters
