Last change on this file since cbce272 was 4e9c7c1, checked in by Thierry Delisle <tdelisle@…>, 7 years ago
Update lex.ll to no longer require libflex.so, since it has name mangling issues on certain machines (e.g. my laptop)
Property mode set to `100644`

384	This rule handles ambiguous cases with operator identifiers, e.g., "int ??()", where the string "??" can be
385	lexed as "?"/"?" or ""/"??". Since it is common practise to put a unary operator juxtaposed to an identifier,
386	e.g., "*i", users will be annoyed if they cannot do this with respect to operator identifiers. Therefore, there is
387	a lexical look-ahead for the second case, with backtracking to return the leading unary operator and then
388	reparsing the trailing operator identifier. Otherwise a space is needed between the unary operator and operator
389	identifier to disambiguate this common case.
390
391	A similar issue occurs with the dereference, *?(...), and routine-call, ?()(...) identifiers. The ambiguity
392	occurs when the deference operator has no parameters, ?() and ?()(...), requiring arbitrary whitespace
393	look-ahead for the routine-call parameter-list to disambiguate. However, the dereference operator must have a
394	parameter/argument to dereference ?(...). Hence, always interpreting the string ?() as * ?() does not preclude
395	any meaningful program.
396
397	The remaining cases are with the increment/decrement operators and conditional expression:
398
399	i++? ...(...);
400	i?++ ...(...);
401
402	requiring arbitrary whitespace look-ahead for the operator parameter-list, even though that interpretation is an
403	incorrect expression (juxtaposed identifiers). Therefore, it is necessary to disambiguate these cases with a
404	space:
405
406	i++ ? i : 0;
407	i? ++i : 0;
