Querying Complete Scoped Identifier Name at Point

Querying Complete Scoped Identifier Name at Point

[Nordlöw]

Has anybody written any extension of symbol-at-point that also
includes in context, which for example in C++ means to prefix it with
its namespace if given.

For example standing somewhere at "vector" in the expression
"std::vector" should return "std::vector" instead of "vector".

This is of course trivial to write. I just wondered if anybody has
written a multi-language interface for this?

Any suggestions on what to call such a function? My suggestion is
scoped-identifier-at-point()

Maybe we should include it thingatpt+.el, Drew?

Thanks in advance,
Nordlöw

I'm no expert on this, but I would think that `:' should simply be declared a
symbol constituent for the language in question, if the fully qualified symbol
name includes the `std::'. Dunno.

If not, that might still be the way to go, but locally only, i.e. for the
purposes of grabbing the symbol.

The functions in `thingatpt+.el' let you specify a syntax-table arg, so you
might be able to get what you want by passing a syntax-table arg that recognizes
`:' as a symbol constituent.
