Build the book
The building workflow requires Nix. After installing Nix, you need to enable the upcoming "flake" feature which must be enabled manually the time being. This is needed to expose the new Nix commands and flakes support that are hidden behind feature-flags.
Afterwards, type nix flake show in the root directory of the project to see
all the available versions of this book. Then type nix build .#<edition> to
build the edition you want (Scala, OCaml, Reason and their printed versions).
For example, to build the Scala edition you'll have to type
nix build .#ctfp-scala. For Haskell (the original version) that is just
nix build .#ctfp.
Upon successful compilation, the PDF file will be placed in the result
directory.
The command nix develop will provide a shell containing all the required
dependencies to build the book manually using the provided Makefile. To build
the ctfp-scala edition, just run make ctfp-scala.
