I have recently tried using Asymptote in python. Following the directions from here:http://asymptote.sourceforge.net/doc/Interactive-mode.html, at the very bottom, it says to place the asymptote.py file on the python path. I have done this, but when I try to execute some code, it gives the error (python is installed in C:\Python27, while asymptote.py is installed in C:\Python27\Lib\site-packages):
-: 4.1: syntax error
error: could not load module '-'
The code inside of asymptote.py is pasted here:
# Python module to feed Asymptote with commands
# (modified from gnuplot.py)
from subprocess import *
class asy:
def __init__(self):
self.session = Popen(['asy', '-quiet', '-interactive'], stdin=PIPE)
self.help()
def send(self, cmd):
self.session.stdin.write(cmd+'\n')
self.session.stdin.flush()
def size(self, size):
self.send("size(%d);" % size)
def draw(self, str):
self.send("draw(%s);" % str)
def fill(self, str):
self.send("fill(%s);" % str)
def clip(self, str):
self.send("clip(%s);" % str)
def label(self, str):
self.send("label(%s);" % str)
def shipout(self, str):
self.send("shipout(\"%s\");" % str)
def erase(self):
self.send("erase();")
def help(self):
print "Asymptote session is open. Available methods are:"
print " help(), size(int), draw(str), fill(str), clip(str), label(str), shipout(str), send(str), erase()"
def __del__(self):
print "closing Asymptote session..."
self.send('quit');
self.session.stdin.close();
self.session.wait()
if __name__=="__main__":
g = asy()
g.size(200)
g.draw("unitcircle")
g.send("draw(unitsquare)")
g.fill("unitsquare, blue")
g.clip("unitcircle")
g.label("\"$O$\", (0,0), SW")
raw_input("press ENTER to continue")
g.erase()
del g
My code:
from asymptote import *
g=asy()
g.size(200)
g.draw("unitcircle")
g.send("draw(unitsquare)")
g.fill("unitsquare, blue")
g.clip("unitcircle")
g.label("\"$O$\", (0,0), SW")
I understand that asymptote.py is only meant to feed commands to asy.exe, and I have Asymptote installed on my computer. How can I resolve this error?
