Using local package

Using local package

[Brett Gilio]

Hi all,

I am wondering about a specific dilemma for developers. I know that I
can run a specific guix environment container of sorts to hack on
package code, but I am curious about how I could do about using that
locally checked out code to build it and run it.

For example, if I git clone emacs and hacked on the source of the
lastest 27.x master branch, what might be the best way to test my
changes without affecting a new revision to my local profile?

Best,
Brett Gilio

You can generate a tarball (e.g. with “make dist”) and then run

    guix build the-package \
         --with-source=the-tarball.tar.gz

“guix build” returns the store path to the newly built item.  It won’t
result in a new generation of your profile.  You can usually run the
software using the full store path.
