Bonjour =C3=A0 tous,

Le pr= ochain Caf=C3=A9 Guix aura lieu  mardi 28 mai =C3=A0 13h en visio sur ce lien : https://meet.univ-grenoble-alpes.fr/b/c= el-dyj-m93-arv

"Les com= mandes guix time-machine et guix describe" anim=C3=A9 par= Marek Fel=C5=A1=C3=B6ci, post-doctorant =C3=A0 l'INRIA et= ICUBE.

R=C3=A9sum=C3= =A9 :

Dans Guix, les paquets l= ogiciels, y compris Guix lui-m=C3=AAme, sont mis =C3=A0 disposition =C3=A0 = travers de ce que l'on appelle les canaux. Au fil du temps, l'offre de paqu= ets dans ces canaux =C3=A9volue. Les versions changent, de nouveaux paquets= ou de nouvelles fonctionnalit=C3=A9s Guix apparaissent, d'autres disparais= sent. Par exemple, en 2021, il =C3=A9tait possible de demander =C3=A0 = Guix de cr=C3=A9er un environnement logiciel avec le paquet Inkscape en ve= rsion 0.92 en utilisant la commande =3Dguix environment --pure --ad-hoc ink= scape@0.92=3D. En 2024, le canal concern=C3=A9 ne propose plus la version 0= .92 d'Inkscape et la commande =3Dguix environment=3D a c=C3=A9d=C3=A9 sa pl= ace =C3=A0  la nouvelle commande =3Dguix shell=3D.

Pour pouvoir r=C3=A9utiliser la ligne de commande et retrouver l'env= ironnement logiciel d'origine, il nous faudrait retourner dans le pass=C3= =A9. Impossible ? Pas pour Guix ! A l'occasion du prochain Caf=C3=A9 Guix, = nous verrons comment utiliser sa machine =C3=A0  voyager dans le temps= , la commande =3Dguix time-machine=3D.

A condition de disposer de la liste des canaux et de leur= s num=C3=A9ros de r=C3=A9visions (commits) respectifs de l'=C3=A9poque, ave= c =3Dguix time-machine=3D, il est alors possible de retourner exactement au= bon moment en 2021. Bien qu'il soit possible d'approximer le bon rep=C3=A8re temporel a posteri= ori, il est pr=C3=A9f=C3=A9rable d'en garder la trace depuis le d=C3=A9but.= Dans ce contexte, nous d=C3=A9couvrirons =C3=A9galement la commande =3Dgui= x describe=3D.


In Guix, software packages, includin= g Guix itself, are made available through so-called channels. Over time, th= e supply of packages in these channels evolves. Versions change, new Guix p= ackages or features appear, others disappear. For example, in 2021, it was = possible to ask Guix to create a software environment with the Inkscape pac= kage version 0.92 using the command =3Dguix environment --pure --ad-hoc ink= scape@0.92=3D. In 2024, the concerned channel no longer offers Inkscape ver= ion 0.92 and the =3Dguix environment=3D command was superseded by the new c= ommand =3Dguix shell=3D. To reuse the initial command line and restore the original software environ= ment, we'd have to go back in time. Impossible? Not for Guix! At the next C= af=C3=A9 Guix, we'll be looking at how to use his time machine, the =3Dguix= time-machine=3D command. Channels, which are in fact versioned git reposit= ories, make it possible to keep track of their changes. With =3Dguix time-m= achine=3D, if you have a list of channels and their respective commit numbe= rs at the time, you can go back to exactly the right moment in 2021. Although it's possible to approximate the correct time marker a posteriori,= it's better to keep track of it from the beginning. In this context, we'll= also discover the =3Dguix describe=3D command.
