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 supports multiple languages within a single file: for example,
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 14.04 LTS. Other Linux
environments should also work, but your mileage may vary.
Ohcount does not support Windows.
Ohcount targets Ruby 1.9.3. The build script requires a bash shell. You
also need a C compiler to build the native extensions.
Ohcount source code is available as a Git repository:
git clone git://github.com/blackducksw/ohcount.git
You will need ragel 6.8 or higher, bash, gperf, libpcre3-dev, libmagic-dev, gcc (version 4.8.2 or greater)
and SWIG (2.0.11). Once you have them, go to the top directory of ohcount and run
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.
