Add CDT Support

[scotthernandez]

Please support the CDT (as well as the JDT).

I'd like to see support for the following features:

• Intellisense
• Build
• Debugging
• Types (hierarchy)
• Call graph
• Editor/Syntax

@scotthernandez At EclipseCon from last week, @marckhouzam began the investigation process of what would be involved in supporting CDT. Let's go ahead and start using this thread to discuss some of the specifications that would be required.

The Che core team is going to add in a C/C++ project type in the next month with build and gdb remote debugger integration at a basic level. But until the CDT port is completed, we will miss out on important intellisense capabilities.

@TylerJewell,

That sounds great. As an aside, I'm excited to see support for LLDB from the CDT multicore debugger side.

While I'm not an eclipse developer I'd be happy to learn more in an effort to get CDT support working. Please call out anything that might need user testing or help.

@scotthernandez - now that Che is adding support for the language server protocol, there will be work started on adding C/C++ with CDT as a language server available over the protocol.

Great news! Looking forward to test and use this.

@ferdaarikan - While it is not CDT itself - the cfe-dev mailing list has indicated that clang is going to have a language server shortly. We will integrate and deploy it as soon as those builds are available.

@TylerJewell thanks for the update, exciting news. Following the same thread I have found a post from Doug Schaefer (cdtdoug,ca) which talks about possibility of plugging cdt into language server.

I can see how clang may be useful to provide the some of the functionality. I am not sure if this will help with features like managed builds that cdt provides.

[TylerJewell]

I suspect that within 12 months, the landscape around language servers will be dramatically different, giving us more options to choose from. Right now, our options feel quite limited. So we are all in a state of wait.

It's been over a year since the last comment on this thread. Is this issue being worked?

I just discovered Codenvy.io / eclipse/che and it is just the tool that I'm looking for with learning C++ development.

Code completion, but especailly syntax highlighting would be great.
codenvy/codenvy#1980 (related issue)

Any work done?

It seems there are plenty of C/C++ langservers out there.

Closing in favor of #13698
