Ohcount is a library for counting lines of source code. It was originally developed at Ohloh, and is used to generate the reports at www.openhub.net.
Ohcount has two main components: a detector which determines the primary language family used by a particular source file, and a parser which provides a line-by-line breakdown of the contents of a source file.
Ohcount includes a command line tool that allows you to count individual files or whole directory trees. It also allows you to find source code files by language family, or to create a detailed annotation of an individual source file.
Ohcount includes a Ruby binding which allows you to directly access its language detection features from a Ruby application.
Ohcount is supported on Ubuntu 18.04 LTS. It has also been tested on Fedora 29. Other unix-like environments should also work, but your mileage may vary.
Ohcount does not support Windows.
Ohcount targets Ruby 2.5.0. The ruby dev headers provided by Ubuntu/Fedora package managers were found to be missing a config.h header file. Installing ruby using brew/rbenv/rvm works better for compiling ohcount.
Ohcount source code is available as a Git repository:
git clone git://github.com/blackducksoftware/ohcount.git

You will need ragel 7.0 or higher, bash, gperf, libpcre3-dev, libmagic-dev, gcc(version 7.3 or greater) and swig (>=3.0.0).
$ sudo apt-get install libpcre3 libpcre3-dev libmagic-dev gperf gcc ragel swig $ ./build
$ sudo dnf install gcc file-devel gperf ragel swig pcre-devel $ ./build
$ brew install libmagic pcre ragel swig $ ./build
For the ruby bindings, there is a dependency for the 'test-unit' gem:
$ gem install test-unit
Once you've built ohcount, the executable program will be at bin/ohcount. The most basic use is to count lines of code in a directory tree. run:
Ohcount support several options. Run
ohcount --help for more information.
Building Ruby and Python Libraries
To build the ruby wrapper:
$ ./build ruby
To build the python wrapper, run
$ python python/setup.py build $ python python/setup.py install
The python wrapper is currently unsupported.
