How do I navigate from a project uri in Rascal to the files it contains?

I would like to parse all the files in a project. Suppose I have a location like |project://p2-SnakesAndLadders|, how can I navigate to the files in the project?

Solution

  • Locations have an ls field, so you could type something like

    |project://p2-SnakesAndLadders|.ls

    to get back all the files and directories at the root level of the project as a list. You can then use functions isFile and isDirectory (both of which are in the prelude, so they are available by default) to distinguish between file and directory locations.
