Re: Packaging Idris2

["Pierre-Henry Fröhring" <contact@phfrohring.com>]

Well, I went from a `guix shell --container' up to `make test' passing ;
assuming a `chez-scheme' backend (no `node' nor `racket'). It boils down
to a shell session looking like:

┌────
│ $ cd ~/src/
│ $ git clone git@github.com:idris-lang/Idris2.git
│ $ cd Idris2
│ $ ./build_idris
└────
Listing 1: session

I guess that an idea would be to « translate » this session into a Guix
Package. What's the best option here? To torture the `gnu-build-system'
until it accepts to build Idris2 or should I take the
`trivial-build-system' route?
Thank you.
