Henrik Lissner c7254e7bdc Major optimization refactor, across the board + enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster startup; ~5-20% general boost + reduce consing, function calls & garbage collection by preferring cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and various cl-lib filter/map/reduce functions) -- where possible + prefer functions with dedicated opcodes, like assq (see byte-defop's in bytecomp.el for more) + prefer pcase & cond (faster) over cl-case + general refactor for code readability + ensure naming & style conventions are adhered to + appease byte-compiler by marking unused variables with underscore + defer minor mode activation to after-init, emacs-startup or window-setup hooks; a customization opportunity for users + ensures custom functionality won't interfere with startup.		2017-06-09 00:47:45 +02:00

:lang cc

This module adds support for the C-family of languages: C, C++, and Objective-C.

Code completion (company-irony)
eldoc support (irony-eldoc)
Syntax-checking (flycheck-irony)
Code navigation (irony)
File Templates (c-mode, c++-mode)
Snippets (cc-mode, c-mode, c++-mode)

C contends with Haskell and Ruby for my favorite language. It's hard to beat this combination of simplicity and power. I've used C for my work since 2009, and it (along with C++) is a personal favorite for game development (with SDL, SFML or, more recently, cocos2d).

The module provides nominal support for Objective-C, which I really only use to inspect generated glue code for iOS mobile apps. Otherwise, I prefer Swift.

Install

This module requires irony-server for most of its features, which depends on cmake and libclang.

MacOS

Due to linking issues, MacOS users must compile irony-server manually:

brew install cmake
brew install llvm  # 1gb+ installation! May take a while!

git clone https://github.com/Sarcasm/irony-mode irony-mode
mkdir irony-mode/server/build
pushd irony-mode/server/build

DEST="$HOME/.emacs.d/.local/$(hostname)/etc/irony-server/"
cmake -DCMAKE_INSTALL_RPATH_USE_LINK_PATH=ON \
      -DCMAKE_INSTALL_PREFIX="$DEST" ../
cmake --build . --use-stderr --config Release --target install

install_name_tool -change @rpath/libclang.dylib \
    /usr/local/opt/llvm/lib/libclang.dylib \
    "$DEST/bin/irony-server"

# cleanup
popd
rm -rf irony-mode

Arch Linux

sudo pacman --needed --noconfirm -S clang cmake

Then run M-x irony-install-server in Emacs.
