Raqm
|
||||
====
|
||||
|
||||
[](https://travis-ci.org/HOST-Oman/libraqm)
|
||||
[](https://ci.appveyor.com/project/HOSTOman/libraqm)
|
||||
|
||||
Raqm is a small library that encapsulates the logic for complex text layout and
|
||||
provides a convenient API.
|
||||
|
||||
It currently provides bidirectional text support (using [FriBiDi][1]), shaping
|
||||
(using [HarfBuzz][2]), and proper script itemization. As a result,
|
||||
Raqm can support most writing systems covered by Unicode.
|
||||
|
||||
The documentation can be accessed on the web at:
|
||||
> http://host-oman.github.io/libraqm/
|
||||
|
||||
Raqm (Arabic: رَقْم) is writing, also number or digit and the Arabic word for
|
||||
digital (رَقَمِيّ) shares the same root, so it is a play on “digital writing”.
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
Raqm depends on the following libraries:
|
||||
* [FreeType][3]
|
||||
* [HarfBuzz][2]
|
||||
* [FriBiDi][1]
|
||||
|
||||
To build the documentation you will also need:
|
||||
* [GTK-Doc][4]
|
||||
|
||||
To install dependencies on Fedora:
|
||||
|
||||
sudo dnf install freetype-devel harfbuzz-devel fribidi-devel gtk-doc
|
||||
|
||||
To install dependencies on Ubuntu:
|
||||
|
||||
sudo apt-get install libfreetype6-dev libharfbuzz-dev libfribidi-dev \
|
||||
gtk-doc-tools
|
||||
|
||||
On Mac OS X you can use Homebrew:
|
||||
|
||||
brew install freetype harfbuzz fribidi gtk-doc
|
||||
export XML_CATALOG_FILES="/usr/local/etc/xml/catalog" # for the docs
|
||||
|
||||
Once you have the source code and the dependencies, you can proceed to build.
|
||||
To do that, run the customary sequence of commands in the source code
|
||||
directory:
|
||||
|
||||
$ ./configure
|
||||
$ make
|
||||
$ make install
|
||||
|
||||
To build the documentation, pass `--enable-gtk-doc` to the `configure` script.
|
||||
|
||||
To run the tests:
|
||||
|
||||
$ make check
|
||||
|
||||
Contributing
|
||||
------------
|
||||
|
||||
Once you have made a change that you are happy with, contribute it back, we’ll
|
||||
be happy to integrate it! Just fork the repository and make a pull request.
|
||||
|
||||
