Interface IParserBuilder<T>

Generate the ELR parser.

Declare top-level NT's.

Generate resolvers to make these definitions left-self-associative.

// 1 - 2 - 3 means (1 - 2) - 3 instead of 1 - (2 - 3)
builder.leftSA({ exp: `exp '-' exp` })

Generate resolvers to implement grammar rules' priorities.

// gr1 > gr2 = gr3
builder.priority(gr1, [gr2, gr3])

Grammar rules with higher priority will always be reduced first, and grammar rules with the same priority will be reduced from left to right.

Resolve a reduce-reduce conflict.

Resolve a reduce-shift conflict.

Generate resolvers to make these definitions right-self-associative.

// a = b = 1 means a = (b = 1) instead of (a = b) = 1
builder.rightSA({ exp: `var '=' exp` })

Apply a function to this builder.
