Nice readings! :-)

Cool!

An example, the recent update of setuptools breaks python2-setuptools.

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix git log --oneline \
>   | grep 'python-setuptools:' | grep Update
b3ca2b4 gnu: python-setuptools: Update to 40.8.0.
d0205df gnu: python-setuptools: Update to 40.0.0.
62a9a23 gnu: python-setuptools: Update to 18.3.1.
d3d656c gnu: python-setuptools: Update to 12.1.
d660f7b gnu: python-setuptools: Update to 31.0.0.
e39d493 gnu: python-setuptools: Update to 41.0.1.

Ah, the order seems weird, “git log” says:

--8<---------------cut here---------------start------------->8---
3142daccbe gnu: python-setuptools: Update to 52.0.0.
e39d4933d1 gnu: python-setuptools: Update to 41.0.1.
b3ca2b45d1 gnu: python-setuptools: Update to 40.8.0.
d0205dfd92 gnu: python-setuptools: Update to 40.0.0.
d660f7be6d gnu: python-setuptools: Update to 31.0.0.
62a9a23bf9 gnu: python-setuptools: Update to 18.3.1.
d3d656c5fb gnu: python-setuptools: Update to 12.1.
--8<---------------cut here---------------end--------------->8---

Well, somehow it is your question about which order. :-)

Doing that, I am thinking of two nice features:

  1. get the parent commits
  2. show a specific commit

For example,

  guix git log --parents=3142daccbe # => 631e1f33
  guix git log --show=3142daccbe

so then I can feed “guix time-machine” with 631e1f33 to have
’python2-setuptools’ before it breaks.  I am not sure to what “--show”
would do.

WDYT?

Hum, ’--grep’ seems missing.  I do not remember, is it not working?
Even slowly?


As discussed, “guix-git-log” is not defined as ’define-command’ because
it should not appear on “guix help”.  However, it should appear with
“guix git --help”.

Well, my idea was something along this attached patch,
