[Qt-creator] Adding support for a new programming language to Qt Creator

[Joseph Rushton Wakeling]

Hello all,

I'm new user of Qt Creator, so please forgive me if the question here is naive 
-- I have tried searching around for an answer without really finding anything 
definitive.

How can one go about adding support for new languages to Qt Creator?  From what 
I have seen there is a fairly substantial collection of syntax highlighting 
rulesets (all derived from Kate?), but these don't necessarily correspond to 
support for things like auto-indentation and obviously don't offer support for 
build or debugging tools.

The language I'm particularly interested in adding support for is D 
<http://dlang.org>.  There is already syntax support in place with a d.xml 
that's taken from Kate (and dates from about 2 years ago).  I'd like to be able 
to extend that with auto-indentation (and if possible autocompletion) support, 
and to be able to add support for compiling and debugging D (it should be 
possible to do this with GDB and LLDB).

I know from the D language forums that about 3 years ago there was some interest 
in adding D support to Qt Creator, but so far as I can see this didn't go beyond 
the syntax highlighting file.

Qt Creator makes a great candidate for a light, fast and effective 
cross-platform IDE which doesn't carry a huge baggage of dependencies, so I'd 
really like to have good D support in it.  Any advice on how to go about doing 
this would be really appreciated.

Thanks and best wishes,
