tree-sitter-peeper

Tree-sitter grammar for the current Peeper language revision.

This grammar targets the new Peeper syntax in this repo, not the older Peeper compiler syntax.

Current coverage

• imports
• top-level let / const
• struct, interface, and enum declarations
• impl T { ... }
• plain function declarations
• generic type/function syntax with <T>
• let / let mut
• if / else
• match
• ^T pointer types and ?T optionals
• array literals and indexing
• postfix ++ / --
• struct literals: .{ x = 1, y = 2 }
• field access and method calls
• comptime parameters and prefix expressions
• structural struct / interface / enum type expressions
• !!, ??, catch

File extension

The grammar is configured for .peep files.

Development

tree-sitter generate
tree-sitter test

To validate the grammar against the compiler sample file:

tree-sitter parse ../PeeperCompiler/x_test/struct_runtime.peep
