Scanners misinterpret -1 #79

Open nathany opened 12 years ago

nathany commented 12 years ago

Most scanners scans expressions like -1 mistakenly as operator(-)integer(1) where it should be returning integer(-1). It's not easy to avoid expressions like i-1 getting highlighted as ident(i)operator(+)integer(1), but it's possible (see Ruby scanner).

I removed the recognition of -1 tokens in r255. This is only a hotfix; to really fix it, we need to keep track of some value_expected state. The Ruby Scanner can do this, and the Scanners for Java, C, Delphi, and Python will need it, too.

Later.

But we should look out for this when implementing new scanners ;)
