Dear Geany Hackers,
I am using Haskell for most of my work and I want to have better
syntactic highlighting for it. After I successfully compiled and
installed Geany on my computer I did some fixes in the lexer. The
patch is attached.
This is the list of problems that I fixed:
- some keywords were not listed in filetypes.haskell
- in Haskell there are some words that are keywords only in some
context. For example here:
import Foo as Bar
'as' is a keyword but in all other contexts it is a normal
identifier. There are some other keywords like that
- The highligthting was failing if the operators are not separated by
spaces. For example here:
10+20
'+' is not highlighted. It worked fine only if I write 10 + 20.
- There was highlighting for data types, classes and instances but it
didn't work correctly. For example:
class Foo x where ....
here Foo is highlighted as class name. Unfortunately this worked
correctly only for very simple cases. For example
this is also correct declaration:
class Eq x => Foo x where
but in this case Eq will be highlighted which the right class name
is Foo. Since this case could be solved only by implementing
a full parser, I just removed this feature. It is not very useful anyway.
I hope that this patch will be added in the main repository. Let me
know if there is some special procedure for sending patches.
Best Regards,
Krasimir
