C4 is an emacs mode for Java 7.
A few notes on variables used in this README
In the examples below I'll mention two variables:
SRC is the location of the project's
BIN is the location of the
bin directory which is created by the build process.
The path to
BIN is affected by the variable
BUILDTYPE, which has two possible values:
Release. Check the Build section for more information.
Install Protocol Buffers before compiling c4. See https://developers.google.com/protocol-buffers/ for more information.
# Fedora dnf -y install protobuf-devel # OSX running macports brew install protobuf-c
You can build c4 in
Debug mode (default), or in
git clone git://github.com/dberg/c4.git cd c4/src make BUILDTYPE=Release
The default compiler is clang if you're running OSX and gcc if you're running GNU/Linux.
You can set the flag
CXX to use your compiler of choice. For example:
make CXX=clang++ # or make CXX=g++
Emacs mode (c4-mode) installation
- Open the file $SRC/c4-mode/c4-mode.el and set the variable
;; Replace BIN with the path to the c4 executable (defvar c4-executable "BIN/c4")
- Add the following to your .emacs or init.el file:
;; Replace SRC with the path to c4-mode (add-to-list 'load-path "SRC/c4-mode") (autoload 'c4j-mode "c4j-mode" "C4 Major mode." t) (add-to-list 'auto-mode-alist '("\\.java$" . c4-mode))
Running c4 from the command line
# Print usage information BIN/c4 --help # Print the emacs output of a java source file BIN/c4 -i java -f MyClass.java
To run all tests execute
Check the Dockerfile for instructions on how to build c4 with Fedora.
