2023-11-22read-print: Properly indent ‘parameterize’.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/65427>. * guix/read-print.scm (%special-forms): Add ‘parameterize’. * tests/read-print.scm: Add test. Reported-by: Maxime Devos <maximedevos@telenet.be> Change-Id: I922bffc527ade539cf2eb304acb25bc9c705a459
2023-09-24read-print: Be more mindful of horizontal space in packages.Tobias Geerinckx-Rice
Perhaps due to their staged nature, packages tend to be ‘lopsided’: deeply nested, with the most elaborate code on the {build,right-hand-,in}side, in snippets and phases. When we indent outer forms too eagerly, we can easily run short on columns by the time we get to the build code, reducing readability. A few strategically-placed newlines early on can make a big difference. * guix/read-print.scm (%newline-forms): Add a newline after opening a <package> source field or an argument list. Compensate by removing the base32 special case, which is now unnecessary.
