Overview
--------

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,
a complex HTML document might include regions of both CSS and JavaScript.

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.

System Requirements
-------------------

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.

Source Code
-----------

Ohcount source code is available as a Git repository:

  git clone git://github.com/blackducksoftware/ohcount.git

Building Ohcount
----------------

> Last updated: 2019-01-28

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).

#### Ubuntu/Debian

```
$ sudo apt-get install libpcre3 libpcre3-dev libmagic-dev gperf gcc ragel swig
$ ./build
```

### Fedora

```
$ sudo dnf install gcc file-devel gperf ragel swig pcre-devel
$ ./build
```

#### OSx

```
$ brew install libmagic pcre ragel swig
$ ./build
```

For the ruby bindings, there is a dependency for the 'test-unit' gem:

```
$ gem install test-unit
```

Using Ohcount
-------------

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:

```
$ bin/ohcount
```

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.
