When a PR requires proof of Guix builds (sha256sums), the PR author or reviewer uses a not well documented command to collect the sha256sums of build outputs or manually gathers them from files:
0guix describe
1uname -m
2find guix-build-$(git rev-parse --short=12 HEAD)/output/ -type f -print0 | env LC_ALL=C sort -z | xargs -r0 sha256sum
This PR introduces a guix-shasums script that gathers all the sha256sums from the output directories and either outputs them on the screen or formats them as Markdown formatted output (to the screen or a file) for easy inclusion in a PR or PR comment. The script is based on the commonly used command (as displayed above)
Example of Markdown formatted output:
