fontconfig 0.1

CFFI bindings for fontconfig

This package try to be a complete python binding for fontconfig.

This package contains two modules: the low level _fontconfig, that matches the C APIs, and fc, that is an higher abstraction over it.

The C API:

int FcGetVersion(void);

in _fontconfig:

_fontconfig.FcGetVersion()

in fc:

fc.get_version()

Installation

This package requires the enum34 package. Install it via pypi:

$ pip install enum34

or use your distribution’s package:

$ apt-get install python-enum34

To compile the _fontconfig extension, the following C headers are required:

#include <fontconfig/fontconfig.h>
#include <fontconfig/fcfreetype.h>
#include <ft2build.h>
#include FT_FREETYPE_H  // usually <freetype/freetype.h>

and the package cffi. In Debian the following packages are enough:

$ apt-get install python-cffi libfontconfig1-dev libfreetype6-dev

Finally, to install the package itself:

$ pip install fontconfig

_fontconfig module

The module _fontconfig exports few simbols to test the capabilities of the underlying library. These are:

• PYFC_HAS_DirCacheRescan
• PYFC_HAS_FcRange

Usage:

>>> import _fontconfig
>>> print _fontconfig.lib.FcGetVersion()
21100
>>> _fontconfig.lib.FcInit()  # init the library
1
>>> config = _fontconfig.lib.FcConfigGetCurrent()
>>> sl = _fontconfig.lib.FcConfigGetConfigDirs(config)
>>> while True:
...  s = _fontconfig.lib.FcStrListNext(sl)
...  if not s:
...   break
...  print _fontconfig.ffi.string(s)  # doctest: +ELLIPSIS
...
/usr/share/fonts
/usr/X11R6/lib/X11/fonts
/usr/local/share/fonts
...
>>> _fontconfig.lib.FcStrListDone(sl)

fc module

The fc module would be an higher abstraction moudule but it is still uncomplete.

Usage:

The same snippet as above:

>>> import fc
>>> fc.get_version()  # fontconfig's version
(2, 11, 0)
>>> fc.init()
>>> config = fc.FcConfig.get_current()
>>> config.get_config_dirs()  # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
['/usr/share/fonts', '/usr/X11R6/lib/X11/fonts',
'/usr/local/share/fonts', ...]

Few more examples:

>>> fc.__version__  # python library's version
'0.1'
>>> pattern = config.get_fonts(fc.SetName.system)[0]
>>> pattern.name_unparse()  # doctest: +ELLIPSIS
'21 Kilobyte Salute:...'
>>> config.get_font_dirs()  # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
['/usr/share/fonts', '/usr/X11R6/lib/X11/fonts',
'/usr/local/share/fonts', ...]
>>> pat = fc.FcPattern.name_parse("dejavu serif")
>>> for font in config.font_list(pat, [fc.PropertyName.file]):
...  print(font.name_unparse())  # doctest: +ELLIPSIS
