Vim settings for C and C++?

Question

Creating new files with c extension comes with processing errors. I was using Clion on my other machines but after giving a thought, I decided to move to vim where I do most of my other languages work.

My dotfile for c and plugins?

Plugin 'luchermitte/lh-cpp'
Plugin 'cscope.vim'
Plugin 'c.vim'

" += C.vim config
let  g:C_UseTool_cmake    = 'yes'
let  g:C_UseTool_doxygen = 'yes'

Errors: I want to resolve these errors.

Answer 1

My lh-cpp plugin comes with dependencies. Whatever plugin manager you use, which isn't VAM nor vim-flavour (the only two that really support dependencies), you'll have to explicitly declare the dependencies for your plugin manager.

I've listed everything you need in the readme . It shouldn't be very complex to adapt it to another plugin manager than the ones I've listed. In case I've made a mistake, or if there are other errors, don't be afraid to open an issue.

What is sure: don't mix plugin managers. Choose one and convert everything you come over to its syntax.

PS: I don't use c.vim, I cannot guarantee you won't observe any conflicts by using both. lh-cpp don't come with snippets for lib C functions, but with those , it has its own Doxygen related features . And (CMake based) compilation , code indexation, project management , etc. are deported to other plugins. See my post on quora on the subject.

Answer 2

The issue is with Plugin 'luchermitte/lh-cpp' as its a plugin pack for c development which contains installing them using Plug not Vundle that made a conflict in my env.

So either you have to remove lh-cpp or change vundle to something like bundle etc.

Also cleared my thoughts with this installation process
