Module type Lrgrep_runtime.ParserSource

A minimal module type mimicking Menhir incremental interface, suitable to run a matching program.

Sourcetype 'a env

Represents the state of the parser (mostly a parsing stack)

Sourcetype element

The type of semantic values stored in stack frame

Sourceval current_state_number : 'a env -> int

Returns the current lr1 state (the state at the top of the stack)

Sourceval top : 'a env -> element option

Returns the semantic value at the top of the stack, if any.

Sourceval pop : 'a env -> 'a env option

Returns the stack with the top frame removed, or None for an empty stack

Sourceval positions : 'a env -> Lexing.position * Lexing.position

Returns the starting and ending positions of the element at the top of the stack
