Initialises the lexing context during the call of the supplied function, which is required for using the lexer. Calls can be nested. Upon termination, emits a warning if the lexer is not in a consistent state (Law context, no pending code content)

Reference, used by the lexer as the mutable state to distinguish whether it is lexing code or law.

The position of the opening token of the last opened context

Updates the current code buffer with the current lexeme. The underlying buffer is used to accumulate the string representation of the body of code being lexed. This string representation is used in the literate programming backends to faithfully capture the spacing pattern of the original program

Flushes the code buffer and returns its contents (see update_acc)

Error-generating helper

Associative list matching each punctuation string part of the Catala syntax with its Surface.Parser token. Same for all the input languages (English, French, etc.)

Calculates the precedence according a matched regex of the form : '#+'

Gets the LAW_HEADING token from the current lexbuf

Simplified tokens for dependency extraction
