how to match a regulas expresion like (%i1) in python pexpect
- by mike
I want to use maxima from python using pexpect, whenever maxima starts it will print a bunch of stuff of this form:
$ maxima
Maxima 5.27.0 http://maxima.sourceforge.net

(%i1)
i would like to start up pexpect like so:
import pexpect
cmd = 'maxima'
child = pexpect.spawn(cmd)
child.expect (' match all that stuff up to and including (%i1)')
child.sendline ('integrate(sin(x),x)')
chil.expect( match (%o1 ) )
print child.before
how do i match the starting banner up to the prompt (%i1)?
and so on, also maxima increments the (%i1)'s by one as the session goes along, so the next expect would be:
child.expect ('match (%i2)')
child.sendline ('integrate(sin(x),x)')
chil.expect( match (%o2 ) )
print child.before
how do i match the (incrementing) integers?
