alex e4b18e85e6 Replaced SourceLocation::isEmpty() with isValid() and hasText(). 
The function SourceLocation::isEmpty() had somewhat dual role.
Sometimes it indicates that the SourceLocation is invalid.
Sometimes it means that there is no corresponding source text.

Hence the proposal is to replace it with two functions, isValid() and hasText().

I also removed Scanner::sourceAt(). (Do we have a rule of thumb to remove unused code?)

Since hasText() checks that start and end are valid indices for source, I adjusted a couple of tests to avoid empty source strings.

Christian Parpart 18e3d6dbca liblangutil: small refactors wrt. API cleanups 
Especially also remove SourceLocation ctor's that the compiler can default-implement.

Christian Parpart 435f7b3b72 liblangutil: Scanner: remove superfluous sourceName field (it's in CharStream already) 
Also, ParserBase::sourceName() was dead code. Eliminating it should
increase test coverage (how sneaky) :-)

Christian Parpart c48a5264be liblangutil: SourceLocation: adds (shared) pointer to underlying CharStream source, eliminating sourceName 
Also, adapted affecting code to those changes.

Christian Parpart 6060a3682c liblangutil: adds Scanner.charStream() accessor 2018-11-29 12:28:57 +01:00
Christian Parpart e4106bd06e Change scanner error diagnostics to be non-intrusive to the token API. 
This also implicitly eliminates the magic-token Token::IllegalHex, and
streamlines error diagnostics over a custom enum class.
 2018-11-24 12:40:51 +01:00
Christian Parpart d67322a186 Introduce namespace langutil in liblangutil directory. 
Also:
- Use {}-style list initialisation for SourceLocation construction
- Introduce new system includes
- Changes the API of the Scanner to take source as value (with move) as opposed to as a reference
