Re: [Rpm-maint] [rpm-software-management/rpm] RFE: Ability to have a file in %files via a command (macro) evaluated at buildtime (#894)
The use-case was to have a `%{pyproject_metadata}` macro like this:
```
%files -n python3-foo
%{pyproject_metadata}
%{python3_sitelib}/foo/
```
The macro would:
* find the built Python dist-info directory, parse the metadata from it,
locate the License-File filed (not yet available) and output something like:
```
%dir %{python_sitelib}/foo-41.4.0.dist-info/
%license %{python_sitelib}/foo-41.4.0.dist-info/INSTALLER
%{python_sitelib}/foo-41.4.0.dist-info/dependency_links.txt
%{python_sitelib}/foo-41.4.0.dist-info/entry_points.txt
%{python_sitelib}/foo-41.4.0.dist-info/LICENSE
%{python_sitelib}/foo-41.4.0.dist-info/METADATA
%{python_sitelib}/foo-41.4.0.dist-info/RECORD
%{python_sitelib}/foo-41.4.0.dist-info/top_level.txt
%{python_sitelib}/foo-41.4.0.dist-info/WHEEL
%{python_sitelib}/foo-41.4.0.dist-info/zip-safe
```
-
Instead, we can have `%{pyproject_install}` to output a special file and use:
```
%files -n python3-foo -f %pyproject_metadata
%{python3_sitelib}/foo/
```

The reason I didn't close this offhand was that I'm curious about the use-case, but apparently forgot to ask about it :) I mean, maybe there is something that we could do to help the case without making %files parsing more special than the rest of the spec. Note that the -f files manifest is macro expanded as well, and that expansion happens just before actually processing the file list. So you can have a macro with (complex) logic expanded at that time, it just needs to be in a files manifest instead of the spec proper. -- You are receiving this because you are subscribed to this thread.

Roger that. I've tried :) -- You are receiving this because you are subscribed to this thread.

That'd require parsing spec %files section without macro expansion, which would
make it completely different from everything else in the spec, and break
legitimate uses. If you take
```
%files
%{one_macro}
%{other_macro}
Those macros might expand to files, or they might expand to new spec sections
or whatever, and there's no telling until you expand the line. Ditto for all
sorts of %if etc logic etc.
This is what -f is for, please use what exists and works.
