Get a Glyph’s path?

colinmford

Does anyone have an easy way to get the path to the .glif file, given a Glyph object?

For a font, you can obviously do this:

>>> font.path

path/to/my.ufo

but FontParts does not have a glyph.path.

In the past I have kludged it together using this, but I don't like this:

import os
from fontTools.misc.filenames import userNameToFileName

g = CurrentGlyph()

fontPath = g.font.path
layerName = "glyphs." + userNameToFileName(g.layer.name) if g.layer.name != g.font.defaultLayerName else "glyphs"
glifName = userNameToFileName(g.name, suffix=".glif")

combined = os.path.join(fontPath, layerName, glifName)
if os.path.exists(combined):
    print(combined)

path/to/my.ufo/glyphs.background/A_.glif

This makes a ton of assumptions that the UFO follows the convention used by the current fontTools.ufoLib (which will potentially not work if the UFO was made by a different package, or even an older version of ufoLib)

Anyone have any better ideas to get .glif file for a RGlyph object without having to make so many assumptions?

Thanks, @frederik!

a cleaner version without using internal objects

import os
from fontTools.ufoLib import UFOReader

def getGlifPath(glyph):
    reader = UFOReader(glyph.font.path)
    # get glyphset for currrent layer
    glyphSet = reader.getGlyphSet(glyph.layer.name)
    # get filename for glyph name
    glifName = glyphSet.glyphNameToFileName(glyph.name, None)
    # glif path = ufo path + layer folder + glif file
    glifPath = os.path.join(glyph.font.path, glyphSet.dirName, glifName)
    return glifPath

g = CurrentGlyph()
print(getGlifPath(g))

@gferreira Much better! And quicker to boot, I think!

Thanks so much!

hello @colinmford,

I gave it a try using the GlyphSet object, this seems to work:

import os

def getGlifPath(glyph):
    # get glyphset for currrent layer
    glyphSet = glyph.naked().layer._glyphSet
    # get filename for glyph name
    glifName = glyphSet.glyphNameToFileName(glyph.name, None)
    # glif path = ufo path + layer folder + glif file
    glifPath = os.path.join(glyph.font.path, glyphSet.dirName, glifName)
    return glifPath

g = CurrentGlyph()
print(getGlifPath(g))

let us know if this works with your data too…

cheers!
