* C/C++/Obj-C

I use C/C++ mostly for developing games. To that end, this module leverages the
[[https://github.com/Sarcasm/irony-mode][irony plugin]] for auto-completion, eldoc documentation and syntax checking (with
flycheck).

Though it provides Objective-C support, I don't use it except to inspect
generated glue code for iOS mobile apps.

+ File templates ([[../../feature/file-templates/templates/c-mode][c-mode]], [[../../feature/file-templates/templates/c++-mode][c++-mode]])
