Which doesn't have any of the
^^^^^/-->ASCII arrows promised in the documentation.
This is because source is a key, that should match grammarSource in options
What is an "identifier of a grammar"?
Literally, this is an identifier, like <anonymous glsl> in your case.
Why is it an array?
Locations in generated errors can have different sources. Well, right now, because #298 does not yet implemented, the source is always one.
Why does format require an array argument? Doesn't it already have error location information, and source lexeme information, to generate a useful error message?
It contains positions in some input, but not the input itself. To show you pretty printed error with a part of the input you should provide it somehow.

@Mingun ah that makes sense. The array thing confused me. Your reply gave me enough information to open https://github.com/peggyjs/peggy/pull/389/files
