    Hi,

    I’m trying to build a script for my features.
    I open (or make) the features.fea file and write stuff into the file.
    The problem is: it’s not updated in the features UI.
    f.update() doesn’t to the trick.

    Who can help?

    Thanks!

    my sketch:

    f = CurrentFont()
g = CurrentGlyph()

path = f._get_path() + "/features.fea"

fea = open(path, "w")

liga = "feature liga { \n"
for g in f:
    if g.name == 'fi':
        liga+= "    sub f i by fi;\n"
    if g.name == 'ffi':
        liga+= "    sub f f i by ffi;\n"
    if g.name == 'fl':
        liga+= "    sub f l by fl;\n"    
liga += "} liga;\n\n"

fea.write(liga)

fea.close()

    mm, why would you rewrite the source file?
    RoboFont will see this change only when you jumped to an other application and back to RoboFont.

    But I strongly encourage you not to do it like this :)

    
f = CurrentFont()

## get the fea text
feaText = f.features.text


for i in range(100):
    feaText += "# halleluja\n"

f.features.text = feaText

    ps: also strongly advised: never ever use private callback, private callbacks are callbacks starting with and “_” (underscore) those allows developers to change underlaying API stuff with bothering the top level API.

    so:

    f = CurrentFont()
print f.path

    thanks

    Yes, this is easier and does exactly what I want!

    Thanks Frederik!
