Bison Declaration Summary

Here is a summary of all Bison declarations:

%union

Declare the collection of data types that semantic values may have (see section The Collection of Value Types).

%token

Declare a terminal symbol (token type name) with no precedence or associativity specified (see section Token Type Names).

%right

Declare a terminal symbol (token type name) that is right-associative (see section Operator Precedence).

%left

Declare a terminal symbol (token type name) that is left-associative (see section Operator Precedence).

%nonassoc

Declare a terminal symbol (token type name) that is nonassociative (using it in a way that would be associative is a syntax error) (see section Operator Precedence).

%type

Declare the type of semantic values for a nonterminal symbol (see section Nonterminal Symbols).

%start

Specify the grammar's start symbol (see section The Start-Symbol).

%expect

Declare the expected number of shift-reduce conflicts (see section Suppressing Conflict Warnings).

%pure_parser

Request a pure (reentrant) parser program (see section A Pure (Reentrant) Parser).
