# deck.gl / luma.gl preset.
#
# deck's `project*` builtins are injected at link time, not written in the shader.
# glslint prefers the *real* signatures resolved from node_modules (see src/deck.rs
# — that part is dynamic and stays in code, enabling hover and go-to-definition into
# the deck source); this preset provides the fallback stub prelude used when deck
# isn't installed, plus detection, so deck is a first-class preset like the others.
#
# `deck = true` opts a dialect into that node_modules resolution. Top-level keys
# (name, deck, prelude) precede the [table] header, per TOML.

name = "deck"
deck = true

# Fallback stub prelude: type-correct, trivial bodies — only the signatures matter
# for checking the consumer shader. Superseded by node_modules signatures when deck
# is installed.

# A shader calling a deck projection builtin is a deck shader. (luma's per-shader
