aerc has the builtin z command that works with zoxide to cd to the appropriate directories. There are a couple of different implementations for the z command, like z.lua, z.sh, z, fasd, which essentially do the same thing. It would be cool if the aerc z-command could support those too.
I'm pretty sure Robin would have nothing against a patch that could generalize the z command to something more configurable. I'm not familiar with the other implementations, but if they all have the same api (
command query [query]andcommand add [path]) then it would be enough to make az-command = zoxideconfiguration setting. If they have a different api, that would make it a bit more complicated I guess. The current code is incommands/z.go.
