[cfe-dev] GSoC project ideas

I'm currently trying to define a project proposal for the Google Summer
of Code. I'm looking for a project that will be at the same time
valuable to Clang and appealing to me. I am mainly interested by the
tooling infrastructure (enhancements to LibClang, LibTooling or work in
After some digging, I have found various options that I would like to
discuss with the community in order to find the best match in terms of
usefulness and "fitability" (~12 weeks).
-- Modules --
I stumbled upon the modularize project (in extra/) and the Module.rst
document. The section "Future Directions" caught my attention.
Available here: http://clang.llvm.org/docs/Modules.html#future-directions
**Improve modularize** interests me but I'm not sure what "better UI"
and "assistant mode" imply. If it's about writing a GUI application I am
not sure it is what I'm looking for the GSoC but maybe it's about
enhanced program options, configuration files and an interactive mode? I
don't know yet how convoluted can be the detection of problems. Might-it
be a fit for the GSoC itself?
I'm also interested by **Detect unused module imports** and **Fix-Its
for missing imports** which I think can fit together under the same
For the **C++ Support**, this is really unclear to me today what are the
implications of such project. What needs to be done and how.
-- Doxygen like tool --
The open Clang projects page has an entry: "Implement a tool to generate
code documentation". I have the feeling that everything that is needed
is already available in the LibClang comment API. What is left is mainly
the generation of the website (or similar). If I am not mistaken then I
am too interested by this project for the GSoC.
-- cpp11-migrate --
I saw this project in extra/ that I find interesting. One idea of
improvement I read is "add the passing by value when move constructor is
available on the stored type".
And some other ideas are also available here:
- Convert member functions begin()/end() to their non-member counterpart.
- Replace tr1 by the C++11 version (drop tr1 namespace and tr1/
include prefix for example).
-- Compilation Database --
I saw a few times on the mailing list the idea of adding an option to
Clang to generate a compile_commands.json. I think only CMake and Ninja
offer such support for now. Clang is supported by more build systems,
having this option could increase the number of projects
"Tooling-friendly". The implementation will have to deal with parallel
compilation jobs but I don't think it's too difficult. Alone this task
is certainly too short for the GSoC.
To finish a few words about me. I'm Guillaume Papin, French student (but
actually doing the 1st year of my Master in Sweden). I chose Clang for
the GSoC because it's a project I follow for some time now (since 2011).
I regularly check the mailing list and I'm in love with the code base
who is very clean IMHO (not only Clang but more generally LLVM). I'm
working on an Emacs package that provides C/C++ completion using
LibClang (still needs a lot of work): https://github.com/Sarcasm/irony-mode.
