NAME

lua.pg - a Lua 5.1 grammar in PGE

DESCRIPTION

GRAMMAR RULES

The grammar rules are according to the original Lua parser as defined lparser.c in the lua distribution.

Helper rules will match a specific token, otherwise a syntax error is generated. These rules make the grammar more readable, so the calls to syntax_error() are not all over the grammar, but only in these rules.

TOKENS

Tokens not defined here (in PGE) are written in PIR in languages/lua/src/lua51.pir.

EXPRESSIONS

Operator precedence is implemented using an optable.
