Add an anchor

qkeave

Simple question, how the heck do I add an anchor? (in python)

qkeave

Thanks!

frederik

see http://docs.python.org/library/pprint.html

import pprint

data = [["nested Item1", "nested Item2", "nested Item3", "nested Item4"], "item1", "item2"]
pprint.pprint(data)

good luck!

Well this is what I used (https://github.com/qkeave/Robofab-tools/blob/master/Radial Guides.py)

PS. How do I enable PrettyPrint on my code?

# Add Radial Guides - Quinn Keaveney

g = CurrentGlyph()
ancs = []
gd = []

for angle in range(0, 180, 15):
    gd.append("Radial {0}deg".format(angle))

for a in g.anchors:
    b = a.name
    ancs.append(b)
    
if 'Radial Guide' not in ancs:
    g.appendAnchor("Radial Guide", (500, 500))

for a in g.guides:
    if a.name in gd:
        g.removeGuide(a)

for a in g.anchors:
    if a.name == 'Radial Guide':
        x = a.x
        y = a.y
        for angle in range(0, 180, 15):
            g.addGuide((x, y), angle, name=("Radial {0}deg".format(angle)))
            guide = g.addGuide((x, y), angle, name=("Radial {0}deg".format(angle)))
            guide.naked().showMeasurements = True

CurrentFont().update() 

print ''
print 'Digested by Python.'

mm, I cannot reproduce this bug

sample script:

glyph = CurrentGlyph()
glyph.clearGuides()

for a in glyph.anchors:
    for angle in range(0, 180, 15):
        guide = glyph.addGuide((a.x, a.y), angle)
        guide.naked().showMeasurements = True

Frederik, you are the man! I really appreciate the programming point.

That being said I want to report a bug. >_<
When you set the measurements via the scripting window it isn't reflected in the WYSIWYG editor, even after CurrentFont().update().

qkeave

Sorry --> double post

frederik

and from a programming point of view it is maybe better to use range(start, end, steps)

# print out an angle between 0° and 360° in steps of 15
for angle in range(0, 360, 15):
    print angle

frederik

As measurements are a UI related attribute, it is not added to the robofab-like guide object.

However you can change the display of measurements of a guide with:

glyph = CurrentGlyph()

guide = glyph.addGuide((100, 100), 90, "my guide")
guide.naked().showMeasurements = True

to remove all guides you can also use glyph.clearGuides()

good luck!

thanks Thom that works,

now I just need to figure how to turn on measurements with python

thom

try this:

g.removeGuide(a)

qkeave

Thanks and sorry! I'm probably not as good at searching as I thought I was.
BUT, this of course leads to more questions.

How do I set guides to measure
How do I ACTUALLY remove guides (because I can't get removeGuide() to work)

I've attached the little tool I'm making below for context.

g = CurrentGlyph()
ancs = []
gd = ['Radial 0deg','Radial 20deg','Radial 40deg','Radial 60deg','Radial 80deg','Radial 100deg','Radial 120deg','Radial 150deg','Radial 160deg']

for a in g.anchors:
    b = a.name
    ancs.append(b)
    
if 'Radial Guide' not in ancs:
    g.appendAnchor("Radial Guide", (500, 500))

for a in g.guides:
    if a.name in gd:
        #THIS IS WHERE I WANT TO REMOVE THE GUIDE
        #removeGuide(a)
    
print g.guides

for a in g.anchors:
    if a.name == 'Radial Guide':
        x = a.x
        y = a.y
        g.addGuide((x, y), 90, name="Radial 0deg")
        g.addGuide((x, y), 110, name="Radial 20deg")
        g.addGuide((x, y), 130, name="Radial 40deg")
        g.addGuide((x, y), 150, name="Radial 60deg")
        g.addGuide((x, y), 170, name="Radial 80deg")
        g.addGuide((x, y), 190, name="Radial 100deg")
        g.addGuide((x, y), 210, name="Radial 120deg")
        g.addGuide((x, y), 230, name="Radial 150deg")
        g.addGuide((x, y), 250, name="Radial 160deg")
        #I JUST NEED TO SET THESE TO MEASURE

print ''
print 'Digested by Python.'

thank you!

frederik

g = CurrentGlyph()
g.appendAnchor("name", (100, 100))
