+;; Commentary:
+;;
+;; Here's how bootstrapping minimal Racket works:
+;;
+;; - Racket BC [CGC] can be built with only a C compiler (except for
+;; one caveat discussed below).
+;; - Racket BC [3M] needs an existing Racket to run "xform",
+;; which transforms its own C source code to add additional annotations
+;; for the precise garbage collector.
+;; - Racket CS needs (bootfiles for) Racket's fork of Chez Scheme.
+;; It also needs an existing Racket to compile Racket-implemented
+;; parts of the runtime system to R6RS libraries.
+;; - Chez Scheme also needs bootfiles for itself, but Racket can simulate
+;; enough of Chez Scheme to load Racket's fork of the Chez Scheme compiler
+;; purely from source into Racket and apply the compiler to itself,
+;; producing the needed bootfiles (albeit very slowly).
+;; Any variant of Racket since version 7.1 can run the simulation.
+;;
+;; So, we build CGC to build 3M to build bootfiles and CS.
+;;
+;; One remaining bootstrapping limitation is that Racket's reader, module
+;; system, and macro expander are implemented in Racket. For Racket CS,
+;; they are compiled to R6RS libraries as discussed above. This note from the
+;; README file applies to all such subsystems:
+;;
+;; The Racket version must be practically the same as the current Racket
+;; verson, although it can be the Racket BC implementation (instead of
+;; the Racket CS implementation).
+;;
+;; Unlike Chez Scheme boot files, the files generated in "schemified"
+;; are human-readable and -editable Scheme code. That provides a way
+;; out of bootstrapping black holes, even without BC.
+;;
+;; However, other Racket subsystems implemented in Racket for Racket CS
+;; use older C implementations for Racket BC, whereas the reader, expander,
+;; and module system were completely replaced with the Racket implementation
+;; as of Racket 7.0.
+;;
+;; For Racket BC, the compiled "linklet" s-expressions (primitive modules)
+;; are embeded in C as a static string constant. Eventually, they are further
+;; compiled by the C-implemented Racket BC bytecode and JIT compilers.
+;; (On platforms where Racket BC's JIT is not supported, yet another compiler
+;; instead compiles the linklets to C code, but this is not a bootstrapping
+;; issue.)

This commit bootstraps the Racket compiler and runtime system from source, including Racket CS as well as both variants of Racket BC. (One remaining limitation is discussed in comments added to gnu/packages/racket.scm.) In the process, it moves to building minimal Racket from the Git repository, rather than the packaged source tarballs. The Git repository is slightly better as the ``corresponding source'': 1. A few packages especially closely tied to the Racket core implementation (like "compiler-lib", "base", and "racket-doc") are developed in the same Git repository. Having them use the same Guix origin, too, will help to keep them in sync. 2. The top-level Makefile in the Git repository is an important ``script[] used to control compilation and installation.'' In particular, it cooperates with the "distro-build" package to create the source tarballs and installers for a Racket distribution. (Racket supports a notion of custom distributions.) 3. It is ``the preferred form ... for making modifications'' to the core Racket implementation. Racket releases are tagged in the Git repository (e.g. "v8.1"). At the beginning of each release cycle, a branch is created to stabilizer a version for extra testing. Active development happens on the "master" branch. * gnu/packages/racket-minimal-sh-via-rktio.patch: Adjust for extra directory layer. * gnu/local/racket.scm (cfg-flag:sh-for-rktio, cfg-flag:enable-lt, cfg-flag:enable-racket, unpack-nanopass+stex, %main-repo-main-distribution-pkgs): New private variables. * gnu/local/racket.scm (racket-minimal)[source]: Use Git. [source](snippet): Unbundle nanopass, stex, and libffi. [native-inputs]: Use racket-bootstrap-chez-bootfiles, plus its dependencies (for Chez, plus a Racket for bootstrap pig). [arguments]: Revise extensively. * gnu/local/racket.scm (racket-minimal-bc-3m, racket-minimal-bc-cgc): New packages, hidden at least for now. (racket-bootstrap-chez-bootfiles): Another new package, but this one is especially likely to stay hidden. * gnu/local/racket.scm (racket)[origin](snippet): Unbundle packages developed in the main Git repository, but leave their links.rktd and pkgs.rktd entries in place. [native-inputs]: Add the main Racket Git repository. [arguments](#:phases): Adjust 'unpack-packages to also unpack package sources from the main Racket Git repository. --- .../patches/racket-minimal-sh-via-rktio.patch | 8 +- gnu/packages/racket.scm | 488 +++++++++++++----- 2 files changed, 359 insertions(+), 137 deletions(-)
