Yes, this bug is now fixed with bug #50831 for Octave version 6, closing as fixed.

I just re-discovered bug #50831, and I think fixing that bug may automatically fix this one, but not tested yet.

It would be nice if the 'pkg' command and its subcommands allow package metadata field names to include hyphens. As of today on the default branch, they are partially supported, but if a field with a hyphen is present, it will silently break loading the cache of installed packages.

Example DESCRIPTION file:


Name: foo
Version: 1.0.0
Date: 2019-05-21
Author: A U Thor
Maintainer: A U Thor
Title: Foo
Description: An example package
Custom-Field: This field should be allowed


The last line is a custom metadata field that currently breaks all installed packages. The 'pkg install' subcommand works correctly, the package does get installed properly and all of its metadata fields do get written to the package cache (local list) file.

However, because the subcommands 'pkg describe', 'pkg list', 'pkg load', and others use the 'load' command, all field names are required to be valid Octave identifiers. The load error is silently suppressed, and it simply looks like no packages are installed.

To resolve this, we should probably have better validation of the field names in the DESCRIPTION file, and possibly transform unsupported characters into underscores if it keeps things easy. We could also error on definitely invalid field names, but I would like to specifically support hyphen separated names.

It would be even nicer to support field names as written without transforming them, but that would probably require a custom load command to parse the package cache file.
