Add 'make glyphlist from font' feature, use Noto fonts to make a Noto collection

davelab6 commented 10 years ago

After #46 is resolved....

The Noto fonts - git repo at http://code.google.com/p/noto - offer a large collection of different writing systems, with carefully curated character and glyph lists. It would be great to compare other fonts to those.

[x] Add a 'compare glyphs' feature which makes a charmap/glyphlist on the fly from the first font and compares subsequent fonts to it.
[x] Add a 'make glyphlist from font' feature that outputs a glyphlist from the glyphs present in a given font
[x] Add a 'make charmap from font' feature as above
[x] Download and run each script over all the Noto fonts to make 2 Noto collections, noto-chars and noto-glyphs, and check them in

Eg

$ pyfontaine --compare-chars font1.ttf font2.ttf;
$ pyfontaine --compare-glyphs font1.ttf font2.ttf;
$ pyfontaine --new-charmap-py NotoSans-Regular.ttf  > notosans-regular.py;
$ pyfontaine --new-glyphmap-py NotoTamilSans-Regular.ttf > nototamilsans-regular.py;
$ pyfontaine --new-charmap-txt NotoSans-Regular.ttf  > notosans-regular.txt;
$ pyfontaine --new-glyphmap-txt NotoTamilSans-Regular.ttf > nototamilsans-regular.txt;

@davelab6 , Please see what has been done already. Few questions. When creating new charmap from font:

Where the output should be written to? plain text file, or python file, like fontaine/charmaps/internals/adobe_latin_1.py? I am confused about this because of changes introduced in issue #46
If it is txt, what format should it be?

73      I      LATIN CAPITAL LETTER I

The same about glyphmap. Should it contain glyphs name and id?

Where the output should be written to?

stdout, as in my example above

what format should it be?

Lets do both. I've updated the main issue text to add this example,

$ pyfontaine --new-charmap-py NotoSans-Regular.ttf  > notosans-regular.py;
$ pyfontaine --new-charmap-txt NotoSans-Regular.ttf  > notosans-regular.txt;

Done. I had to read few articles and wiki pages in order to understand character vs glyph and what should be done :)

I am confused by this. Under fontaine/charmaps/internals there are *.py files, so what they are? charmaps or glyphmaps? fontaine/charmaps/internals/adobe_latin_1.py The class name is class Charmap: but method is def glyphs(self):

davelab6 commented 10 years ago

The method name is misleading and arbitrary :) change it to

def charset:
