How to exclude packages from binary built based on suffix?

[nagmat84]

I would like to avoid building binary packages for packages which end with "-meta" and "-bin" on my build server. To this end, I followed the guide Gentoo Wiki: Vinary Package Guide - Excluding creation of Some Packages. My current "EMERGE_DEFAULT_OPTS=" contains

I went through this when first deciding to use binary packages. Since I've got around 10 VMs now, I've found that excluding pre-built binaries just doesn't give me much of a benefit. In fact, it may actually help with some larger packages (like browsers, kernels, or Rust). With the binaries stored on an NFS server, as opposed to the internet, I find that these packages install much faster. And since disk space is so cheap, that's not much of a factor anymore, either.

Can you describe your current environment in more detail?

From a few minutes looking at the Portage source, I think the string you give is handled by portage.dep.Atom with allow_wildcard=True. This uses _get_atom_wildcard_re to decompose your input into pieces. Perhaps reviewing this regular expression will help with your question.

After quickly glancing trough some manpages about ATOMs, I think you may have encountered a bug.
Because I don't see why would */*-bin match anything other than package names ending with -bin.

But after running quick tests on one of my boxes, I did not encounter this problem.
