process.stdin.resume()

transform a stream of glsl-parser AST nodes into strings.

only operates on top-level statements emitted by glsl-parser, so the code it emits is executable by webgl.

api

deparser(whitespace_enabled=true, tab_text=' ')

Creates a readable/writable stream.

If no args are provided, whitespace is assumed to be enabled, and the tab text will be ' '.

If you pass false for the first arg, only syntactically significant whitespace will be emitted (it'll behave like a poor man's minifier).

If you pass true and tab text, that tab text will be used to indent code.

note

the big caveat is that preprocessor if statements (#if*, #endif) won't work unless each branch produces a parseable tree.
