A tree-sitter grammar for Nim.
The goal is to parse a superset of Nim and create a syntax tree that can be easily ingested by tools.
Generating this parser take around 7GiB of memory. Any help in reducing the parser size is appreciated.
Right now the parser is capable of parsing all of Nim, with exceptions for old and mostly unused/dead syntax, including:
-
Package-level objects (ie.
type X.Y = ref Z) -
Variable declaration with dots for "partial" objects (ie.
let x.y = z). -
Covariance in generics for imported types (ie.
type X[out T] = Z).
These were omitted due as they are a product of old language experiments that never caught on, and omitting them allows for simpler and more compact parser, but support might be added on request.
The parser correctness has not been thoroughly tested.
Node names and structures are not expected to change between releases.
