src/core/packages/parsing.sgl

1;;; Incremental parsing.

2;;;

3;;; tree-sitter is what the `*-ts-mode` major modes in Emacs 29+ are built on.

4;;;

5;;; NOTE FOR ANYONE ADDING A PACKAGE: this is the first definition in the

6;;; channel that does not fit the configure/make/install shape the phase model

7;;; assumes. tree-sitter ships **no configure script** -- it is a plain

8;;; Makefile driven by `PREFIX`/`DESTDIR` -- so the `configure` phase is simply

9;;; omitted and `PREFIX=${out}` is passed to both remaining phases. `${out}`

10;;; expands to this package's own store prefix, and a command-line assignment

11;;; overrides the Makefile's `PREFIX ?= /usr/local`.

12;;;

13;;; This works, but only because tree-sitter's Makefile happens to accept the

14;;; two variables the model already passes. A package needing an `autoreconf`

15;;; or a CMake configure step still has no expression here: `run` phases and

16;;; `env:` are sealed by package-v2 but refused at publish until Stage 2.
