text parsing?

We have several cnc mills that we need to backup the programs on. The problem is that the mills use basic serial communication and when you tell it to send all programs it sends them all as one long text file. I would like to find a script or parsing program to go through this file and break it into individual files with the "program name".nc type format with a % added to the start and end of the file.
like this

long text file.nc
o05050
g123 m23 g234
g222 m222 g44
o05150
g888 m22 g333
m222 g333 m444
o05250
g123 m23 g234
g222 m222 g44

output
o05050.nc
%
g123 m23 g234
g222 m222 g44
%

o05150.nc
%
g888 m22 g333
m222 g333 m444
%
and so on the letter o appears only at the start of program names and nowhere in the program codes so at the moment we are doing a crtl-f cut/paste thing but there has got to be a better way. any ideas?

could probably ask someone in an entry level C++ or Java class to write a simple parser

here

parsecnc.py

Code




import os, sys





cncfile=open(sys.argv[1],'r')


f=cncfile.read()


f=f.splitlines()





def dumpprog(line,filename):


    wri = open(filename,'a')


    line=line + '\n'


    wri.write(line)


    


w='defaultoutput.nc'





while len(f)>0:


        line = f.pop(0)


        if line.find('o')==0: 


            dumpprog('%',w) 


            w=line + '.nc'


            dumpprog('%',w) 


            line=[]


        if len(line)>0: dumpprog(line,w)


dumpprog('%',w)

Usage: python parsecnc.py filename

Example

$mkdir ~/tmp2929
$cd ~/tmp2929
$python ~/workspace/souperparser/src/parsecnc.py ~/cnctest
$ls
o05050.nc o05150.nc o05250.nc defaultoutput.nc
$cat o05050.nc
%
g123 m23 g234
g222 m222 g44
%

sorry I hadn't replied on this unfortunatly I'm still waiting for IT to give me enough access to install python, but playing with it at home it seems to be working. I'll let you know if/when I hear from IT on it. thanks for your help LC

Let me know what you find out. I can quickly change something if need be.

Python is most excellent.

Funny story that was. IT said no, so there I am sitting in the office doing it by hand for the third day and the boss walks in and asks what I'm doing. I'm really sick of staring at my laptop so I sorta went off while telling him. He says there ought to be a program that can do that. I said there is but IT won't let me install it. He says fuck that email it to them and let them do it. I don't know if they ever got something to parse the files but I would imagine they did as this is a monthly ritual and we add several programs a month.
