pyfontaine

pyfontaine analyses fonts for their language and character set support.

It has a straightforward pythonic character set definition format (simple example, medium example, complex example)

To add new definitions, just add files to the internals directory - they are autodetected!

It also downloads additional definitions from the Extensis, font-config and Unicode websites.

Installation

On Mac OS X, install the pyicu dependency as follows:

CFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib pip install pyicu;

Install the latest release easily with the pip installer:

sudo pip install fontaine

To install the latest development version:

git clone https://github.com/davelab6/pyfontaine.git;
cd pyfontaine;
sudo python setup.py install;

Usage

Given a font, it returns a report with some general metadata and th language support analysis:

sh pyfontaine font.ttf;

Given a unicode character value, it returns a list of character sets that include that character.:

pyfontaine 0x0061;

To output font reports in various formats:

pyfontaine --xml font.ttf;
pyfontaine --json font.ttf;
pyfontaine --csv font.ttf;
pyfontaine --wiki font.ttf;

The --wiki format produces a MediaWiki table (example <https://en.wikipedia.org/wiki/DejaVu_fonts#Unicode_coverage>__)

To only show character sets from different collections:

pyfontaine --collections all font.ttf; # default
pyfontaine --collections pyfontaine font.ttf;
pyfontaine --collections uniblocks font.ttf;
pyfontaine --collections extensis font.ttf;
pyfontaine --collections fontconfig font.ttf;
pyfontaine --collections cldr font.ttf;
pyfontaine --collections subsets font.ttf;

To only show specific character sets:

pyfontaine --set African,'Basic Latin','GWF vietnamese' font.ttf;

To print a list of all the missing unicode values from each set:

pyfontaine --missing font.ttf;

To output visualisations of the coverage using Hilbert curves (thanks for the idea, Øyvind 'pippin' Kolås!): sh pyfontaine --coverage font.ttf; ls -l coverage_pngs/; (The PNG files are stored in a new directory, coverage_pngs, under the current directory.)

Update collection data

You can update all related text and xml data for collections in realtime with argument --update-data. Note. --update-data requires internet connections.

python --update-data font.ttf

Python Module

It has a python module. Here is an example script from the Font Bakery project.

Thanks

We would like to thank some upstream projects that make pyfontaine even more useful: * Thomas Phinney for the WebINK Character Sets * Behdad Esfabod for the font-config languages definitions * Unicode Consortium for the Unicode Blocks
