chroma at render time, emitting CSS classes rather than inline colour, handed to
a `code` theme fragment. Highlighting works with scripting off, in a feed
reader, in a browser that never runs JavaScript. No lighter pure-Go option
exists — every "alternative to chroma" is JavaScript, which the reference theme
is gated against.
A fence's info string carries the rest: title, numbers, start, hl=3,7-9, and
file=name lines=A-B, which reads the snippet out of a file beside the bundle and
numbers it by that file's own lines. So a post quotes several parts of one
program without the copies drifting from it, and a reader can find what they are
looking at. Verified on the real binary: the same file at lines 5-10 and 12-14,
each numbered as it really is, with different lines tinted.
Not a new package: a new one could not import the key=value parser this repo
already has, because ADR-0069 forbids a feature importing its sibling, and a
second parser for the same syntax is what §6 stops.
Two costs, both stated in the ADR rather than buried. The binary goes from ~15MB
to 19MB, for a project whose story is one small binary. And the reference theme
now carries a token palette — the first thing in it that is a taste rather than
a demonstration — kept to eight classes for that reason.
The demo quotes a shell file, not a Go one: a .go file under examples/ joins the
module and has to compile, which the build gate caught before it shipped.
