silnrsi / feax Goto Github PK

@mhosken,

In read_classes() which, as you know, is used to read and process a classes.xml file, there is this code:

Line 105 seems to be trying to recognize classnames such as someclass[3], i.e., the name of a class followed by an index.

I might have seen that kind of thing in an Attachment Point database after "adding" a classes.xml that includes "fixed" classes (see where this was added). But I've never seen it within actual classes.xml files, which is what this code is reading. Do you have examples?

Am I missing something?

I would think, if anything, this code might be looking for the fixed attribute on the class, but for FEA rules the glyphs are already kept in the order they are written in the code (rather than sorted by numeric glyphID like GDL does).

For reference, here are bug reports in pysilfont that related to feax processing -- I suspect we'll need to fix these before others will be interested in this module.

• silnrsi/pysilfont#86 — Fixed in commit adfd22c
• silnrsi/pysilfont#70
• silnrsi/pysilfont#65
• silnrsi/pysilfont#64

The documentation refers to Myanmar Great Ya. But the example is about U+103C, which is medial ra.
