Compiling YCM with semantic support for C-family languages:

cd ~/.vim/bundle/YouCompleteMe

./install.py --clang-completer

Compiling YCM without semantic support for C-family languages:

cd ~/.vim/bundle/YouCompleteMe

./install.py

The following additional language support options are available:

• C# support: install Mono and add --omnisharp-completer when calling ./install.py.
• Go support: install Go and add --gocode-completer when calling ./install.py.
• TypeScript support: install Node.js and npm then install the TypeScript SDK with npm install -g typescript.
• JavaScript support: install Node.js and npm and add --tern-completer when calling ./install.py.
• Rust support: install Rust and add --racer-completer when calling ./install.py.

To simply compile with everything enabled, there's a --all flag. So, to install with all language features, ensure xbuild, go, tsserver, node, npm, rustc, and cargo tools are installed and in your PATH, then simply run:

cd ~/.vim/bundle/YouCompleteMe

./install.py --all
