Function BuildConfig

internal/configs/config_build.go:29–50

BuildConfig constructs a Config from a root module by loading all of its descendent modules via the given ModuleWalker. The result is a module tree that has so far only had basic module- and file-level invariants validated. If the returned diagnostics contains errors, the returned module tree may b

(ctx context.Context, root *Module, walker ModuleWalker)

// the returned module tree may be incomplete but can still be used carefully
// for static analysis.
func BuildConfig(ctx context.Context, root *Module, walker ModuleWalker) (*Config, hcl.Diagnostics) {
	var diags hcl.Diagnostics
	cfg := &Config{
		Module: root,
	}
	cfg.Root = cfg // Root module is self-referential.
	cfg.Children, diags = buildChildModules(ctx, cfg, walker)
	diags = append(diags, buildTestModules(ctx, cfg, walker)...)

	// Skip provider resolution if there are any errors, since the provider
	// configurations themselves may not be valid.
	if !diags.HasErrors() {
		// Now that the config is built, we can connect the provider names to all
		// the known types for validation.
		providers := cfg.resolveProviderTypes()
		cfg.resolveProviderTypesForTests(providers)
