Also affected by this, 'pkg install' may find incompatible oct files under the or any arbitrary other files that contain something that looks like it should be an Octave file, which could cause a docstring extraction error.

Found when trying to install the same package for use by multiple versions of Octave at the same time. Octave errors when it finds oct files that were compiled for a different API version, even though they are in a correctly labeled API directory.

When installing a package, the local function 'generate_lookfor_cache' uses 'genpath' to find all subdirectories of a package when extracting docstrings.

A package may contain an 'inst' directory with subdirectories that aren't added to the load path when the package is actually used, and they should not be included in the docstring cache.

So ideally, the 'generate_lookfor_cache' will call 'addpath' to determine which subdirectories are actually going to be added to the path (e.g. with PKG_ADD).

Examples

  • A package may have an 'inst/contrib', 'inst/examples', or 'inst/legacy' subdirectory with m-files that the maintainer doesn't want added to the load path by default.
  • A package may have an 'inst/octave-7' subdirectory with m-files copied from a newer version of Octave that should only be loaded conditionally.
