startup?

Hi,

I'm using NB to create slides. It's a bit eccentric but works much better than powerpoint/impress (which I hate) and than TeX approaches I used (too boring).
I created a sort of css file, which I import with exec.

I needed arrows, so I defined this which seems to work fine:

def arLine(x1, y1, x2, y2, double = False):
    [x1, x2, y1, y2] = [float(x1), float(x2), float(y1), float(y2)]
    l = sqrt((x2-x1)**2 + (y2-y1)**2)
    line(x1, y1, x2, y2)
    if y2 > y1:
        q = asin((x2-x1)/l)+pi*3*0.5
    elif y2 < y1:
        q = -asin((x2-x1)/l)+pi*0.5      
    elif y2 == y1:
        q = 0
    push()
    translate(x1, y1)
    transform(CORNER)
    rotate(radians=q)
    beginpath(l, 0)
    lineto(l-10, -5)
    lineto(l-10, 5)
    endpath()
    if double:
        beginpath(0, 0)
        lineto(0+10, -5)
        lineto(0+10, 5)
        endpath()    
    pop()

Autoreply. Hmm, Ok, I can put a module in ApplicationSupport. So, just need a startup file.
Best

Ok, my idea was to put a module (e.g. "misc") inside Application Support/NodeBox. In the misc module I have the definitions of some functions using NodeBox' commands, e.g line.
However, if I do in a new script:

from misc import *

from  nodebox import *

Hi,

I think the ximport command is what you need. The imported module gets access to a "_ctx" variable, that has all the NodeBox commands, such as _ctx.line(10, 20, 30, 40) .

For more info, check out the docs:

Kind regards,

Hi Frederik,

thanks. I've been able to create a package by putting a folder "andrea" with an __init__.py file into app support containing e.g.:

def myline(a,b,c,d):
    return _ctx.line(a,b,c,d)

a = ximport("andrea")
 
strokewidth(10)
stroke(color(0,0,0))
a.myline(40, 50, 60, 154)

def circle(x, y, radius, other = None):
    if other == None:
        other = radius
    return oval(x-radius*0.5, y-other*0.5, radius, other)

a = ximport("andrea")
 
strokewidth(10)
stroke(color(0,0,0))
a.myline(40, 50, 60, 154)
