Hello!
I’ve pushed my “train hacks”, which are a continuation of refactoring
work I had done in December (ca. 64ec0e2):
• ‘guix build’ has a new ‘--with-input’ option to rewrite the
dependency graph so you can run:
guix build guix --with-input=guile=guile-next
and guess what it does. :-)
However, it only works for explicit inputs.
• ‘guix package’ supports ‘--with-source’ and ‘--with-input’, with the
caveat that such transformations are forgotten upon upgrades.
• There’s a fairly generic package transformation framework in (guix
scripts build).
• The documentation of command-line build options is a bit improved,
with subsections for each category of options.
Feedback welcome!
Ludo’.
