Method modRelPath

cmd/dagger/shell_fs.go:583–595

modRelPath returns the relative path to a module's root dir from workdir If the target module is on a different source/context, the absolute ref is returned instead.

(def *moduleDef)

// If the target module is on a different source/context, the absolute ref
// is returned instead.
func (h *shellCallHandler) modRelPath(def *moduleDef) string {
	if srcRoot, _ := h.contextModRef(def.SourceRootSubpath); srcRoot == def.SourceRoot {
		// use relative path if it's shorter
		path, err := filepath.Rel(h.workdirAbsPath(), def.SourceRootSubpath)
		if err == nil {
			if len(path) > len(def.SourceRootSubpath) {
				path = def.SourceRootSubpath
			}
			return path
		}
	}
	return def.SourceRoot
}

// IsDefaultModule returns true if the given module reference points to
// the current context's module
