Hello Divya! I would like to show interest in having a Guile based build-tool. If the community decides this is something worth putting effort into, I would like to participate.
While I don’t have a specific starting point in mind, I believe that an essential feature such a tool, is the ability of continuing builds from successful phases. This is better described in this issue[1] where Nicolas made great progress towards allowing Guix to do it. [1]: https://issues.guix.gnu.org/68315 Thanks for showing interest in improving Guix! Regards, Sergio
