Hi Richard I've already started implementing user defined literals syntactically. Code is in gerrit (https://git.eclipse.org/r/6000). Regarding your question. As far as I know the standard does not explicitly require a space between "" and the following identifier. But it is not
possible according to the lexical conventions to have a matching token sequence for a literal operator. If we consider an example: float operator ""E(const char*); This is invalid as ""E would yield only one token, a user defined string literal, instead of "" and E as separate tokens. As you run into this
problem, you might not yet have the corresponding adaption in the lexer. Regards Thomas From: cdt-dev-bounces@xxxxxxxxxxx [mailto:cdt-dev-bounces@xxxxxxxxxxx]
On Behalf Of Richard Hello CDT mailing list, I'm taking a stab at fixing bug #379684 User-defined literals, mostly just for the fun of it, but I'm probably going to need a lot of help as this is my first time in the eclipse/cdt internals. Anyway, I have managed to get the parser to recognise the T operator "" L() syntax, with one caveat: I can't figure out how to require the whitespace between the "" and the literal name. Thanks, Richard. |
