Hi,
So there were some comments on https://news.ycombinator.com/item?id=32960308
about getting started with contributing to Guix.
It turns out that the barrier of entry for editing existing packages is
kinda high (I tried it myself--putting myself into the mindset of a
beginner).
For example:
(1) Install the guix system
(2) Log in as regular user
(3) guix edit nano
(4) It opens a file from /gnu/store that you cannot edit.
Uhh. That's... not ideal. Maybe instead error out with a hint on what you need
to do in order to provide a local checkout? Or do we want viewing to work?
Ok, so let's say we are a little more knowledgeable:
(1) Install the guix system
(2) Log in as regular user
(3a) if [ ! -d src ]
then
mkdir src
cd src
else
cd src
fi \
&& if [ ! -d guix ]
then
git clone --depth=1 https://git.savannah.gnu.org/git/guix.git guix
else
(cd guix && git pull --rebase)
fi \
&& cd guix \
&& guix shell -C -D guix -- ./bootstrap \
&& guix shell -C -D guix -- ./configure --localstatedir=/var --disable-daemon
\
&& guix shell -C -D guix -- make -j5 \ <--- takes forever to build
&& ./pre-inst-env guix edit nano \
&& git add gnu/packages/*.scm
Ok, that worked.
But there are a lot of ways that can be done wrong.
Weird way it can be done wrong:
(1) install the guix system
(2) log in as regular user
(3b) git clone --depth=1 https://git.savannah.gnu.org/git/guix.git guix \
&& cd guix \
&& guix shell -C -D guix -- ./bootstrap \
&& guix shell -C -D guix -- ./configure --localstatedir=/var --disable-daemon
\
&& ./pre-inst-env guix edit nano
It will open the file in /gnu/store . WTF? I'm pretty sure that that's a bug.
./pre-inst-env does exist--but it does some weird things if you don't
compile beforehand.
Also, can we put a variant of (3a) into a command "guix prepare-edit" or
something?
It has always bothered me how manual and magical-commandy it is otherwise
(what you actually need to do also changed over the years--not good).
