If you use a path in font(filePath) then the path is relative to the current directory (which is not always the the directory of the python file)

DrawBot the app set the current directory to the .py file directory. When used as module this does not happen.

So either set the a correct current directory or get a absolute path from the .py file: os.path.join(os.path.basename(__file__), "font.otf")

cool way to make a rounded rect!

there are already a roundedRect example in the repository: see https://github.com/typemytype/drawbot/blob/master/examples/roundedRect.py

I would encourage you to make a python package out of your helper tools that you import when you needed it...

# a separate file with the name "roundedRect.py"
def roundedRect(...):
    # draw your stuff here

# an other file in the same directory

#  name of the file/module  name of the function 
from roundedRect import roundedRect

# call it
roundedRect(...)

hope this makes sense!

that is way to complex

Variable works fine with the UI of drawBot... dont use it outside a drawBot document

You will have more control when you build it with vanilla and use this in a drawBot packages.

import vanilla


class MyController:
    
    def __init__(self):
        self.w = vanilla.Window((150, 40), "My Tool Name")
        self.w.slider = vanilla.Slider((10, 10, -10, 22), callback=self.sliderCallback)
        self.w.open()
    
    def sliderCallback(self, sender):        
        x = sender.get()
        newDrawing()
        fill(random(), random(), random())
        oval(x, 0, 1000, 1000)
        saveImage('/Users/frederik/Desktop/issueDrawBotPackage/test.pdf')
        endDrawing()
    

MyController()

this script wrapped in a .drawBot package

this should work!

You can open the debugger in drawBot by hitten alt with the help menu open.

If drawBot is installed as a module you can access it anywhere!

If Variable(..) is a key thing in your script, use a drawBot package, where you can set a main script that gets executed when the file is opened in DrawBot.app.

yes, thanks @jo

possible with cmd + arrows keys or cmd + click when ever True or False is selected

Some parts of drawBots api don't work automatically outside the application, mainly parts where an UI is involved.

But first why building an app?

I would recommend UI parts to build separately. Build a window with vanilla, add some sliders and callback whenever that slider will change.

DrawBot has a drawBot package, so drawBot code can be shared without looking a complex script folder structure: https://www.drawbot.com/content/drawBotApp/drawBotPackage.html

expanding Gustavo's example:

import colorsys

path = bytes('http://www.drawbot.com/', 'utf-8')

w, h = 31, 31
s = 10

size(w*s, h*s)

img = ImageObject()
img.QRCodeGenerator((w, h), path, 'Q')

iw, ih = img.size()

t = ""

for y in reversed(range(int(ih))):
    for x in range(int(iw)):
        r, g, b, a = imagePixelColor(img, (x, y))
        _, l, _ = colorsys.rgb_to_hls(r, g, b)
        if l < 0.51:
            fill(0)            
            rect(x*s, y*s, s, s)
            t += "W"
        else:
            t += " "
    
    t += "\n"

newPage()
font("Menlo", 16)
lineHeight(10)
textBox(t, (0, 0, width(), height()))
print(t)

and the corners are always the same

DrawBot is using CoreText to layout text. This is the same engine as TextEdit.app, and it seems this is also not possible there...

this works...

from fontTools.misc.bezierTools import calcCubicArcLength


pt1 = 100, 100
pt2 = 200, 100
pt3 = 400, 150
pt4 = 400, 400

l = calcCubicArcLength(pt1, pt2, pt3, pt4)

path = BezierPath()
path.moveTo(pt1)
path.curveTo(pt2, pt3, pt4)

text(str(l), pt3)

fill(None)
stroke(0)
drawPath(path)
