Request for estimation cost/price of creation KDevelop plugin for D language

Hi Energo,

thank you very much for your interest in KDevelop and your trust in our 
community to do such a project.

However, there are several things I think you should consider:

  - The D language was never particularly successful. It has been around 
as C++'s touted "successor" for decades, but has at no point in time 
gained significant traction. A much more successful, relatively direct 
competitor to C++ is Rust.

  - Maybe you will find someone to develop this for you on this list but 
most people contributing to KDevelop do so in their free time. Unless 
people have considerable personal interest in this feature (which is 
unlikely since, as said, D isn't a language I ever have seen or heard 
anyone use), writing a language plugin isn't something you do after work 
just like that.

Writing a language plugin with completion, highlighting, navigation, 
debugger, launcher, compiler settings, and even some installation help 
and stuff is a project for 6-12 months. It basically requires someone to 
quit their full-time job to do your project instead. That's unlikely to 
happen, even if you offer the required $50-100k cash for that.

Pragmatically, a more realistic path is looking into Rust, for which 
both a KDevelop plugin (unmaintained unfortunately) [1] as well as LSP 
support in kate [2] somewhat exist already. Maybe you can gather some 
traction to update/improve those, that would be very cool. I think here 
it is also way more realistic to motivate someone with a few euros to 
spend a few weekends on improvements.
