Congrats Chris! :-) On Wed, 13 Sep 2023 at 13:13, Maxim Cournoyer w= rote: > I had some musing about the daemon recently; I was thinking libguile > could be added to our old C++ daemon, which could then replace its > functions piece-wise with Scheme implemented ones? Maxim, you are proposing to keep the C++ and gradually replace some parts by implementing these parts in Guile and add a C layer via libguile to call the Guile code from the C++, right? If I remember correctly from the last discussion on Guile guix-daemon, I proposed the converse. However, the C layer of Maxim=E2=80=99s proposal se= ems much easier. ;-) Some gradual replacements seem a good strategy for the feedback loop. However, the final design would be more or less the same as the current one. Although, I do not know if another design would be possible. :-) Chris, all the best for this challenging project! It=E2=80=99s nice that y= ou have a grant and I am convinced all the ingredients are here for making this project a success. :-) Cheers, simon
