Hi all,
I am using python to drive another tool using pexpect. The values
which I get back I would like to automatically put into a list if there
is more than one return value. They provide me a way to see that the
data is in set by parenthesising it.
This is all generated as I said using pexpect - Here is how I use it..
child = pexpect.spawn( _buildCadenceExe(), timeout=timeout)
child.sendline("somefunction()")
child.expect("> ")
data=child.before
Given this data can take on several shapes:
Single return value -- THIS IS THE ONE I CAN'T GET TO WORK..
data = 'somefunction()\r\n"@(#)$CDS: icfb.exe version 5.1.0 05/22/2005
23:36 (cicln01) $"\r\n'
Multiple return value
data = 'somefunction()\r\n("." "~"
"/eda/ic_5.10.41.500.1.18/tools.lnx86/dfII/samples/techfile")\r\n'
It may take up several lines...
data = 'somefunction()\r\n("." "~"
\r\n"/eda/ic_5.10.41.500.1.18/tools.lnx86/dfII/samples/techfile"\r\n"foo")\r\n'
So if you're still reading this I want to parse out data. Here are the
rules...
- Line 1 ALWAYS is the calling function whatever is there (except
"\r\n") should be kept as "original"
- Anything may occur inside the quotations - I don't care what's in
there per se but it must be maintained.
- Parenthesed items I want to be pushed into a list. I haven't run
into a case where you have nested paren's but that not to say it won't
happen...
So here is my code.. Pardon my hack job..
import os,re
def main(data=None):
# Get rid of the annoying \r's
dat=data.split("\r")
data="".join(dat)
# Remove the first line - that is the original call
dat = data.split("\n")
original=dat[0]
del dat[0]
print "Original", original
# Now join all of the remaining lines
retl="".join(dat)
# self.logger.debug("Original = \'%s\'" % original)
try:
# Get rid of the parenthesis
parmatcher = re.compile( r'\(([^()]*)\)' )
parmatch = parmatcher.search(retl)
# Get rid of the first and last quotes
qrmatcher = re.compile( r'\"([^()]*)\"' )
qrmatch = qrmatcher.search(parmatch.group(1))
# Split the items
qmatch=re.compile(r'\"\s+\"')
results = qmatch.split(qrmatch.group(1))
except:
qrmatcher = re.compile( r'\"([^()]*)\"' )
qrmatch = qrmatcher.search(retl)
# Split the items
qmatch=re.compile(r'\"\s+\"')
results = qmatch.split(qrmatch.group(1))
print "Orig", original, "Results", results
return original,results
# General run..
if __name__ == '__main__':
# data = 'someFunction\r\n "test" "foo"\r\n'
# data = 'someFunction\r\n "test foo"\r\n'
data = 'getVersion()\r\n"@(#)$CDS: icfb.exe version 5.1.0
05/22/2005 23:36 (cicln01) $"\r\n'
# data = 'someFunction\r\n ("test" "test1" "foo aasdfasdf"\r\n
"newline" "test2")\r\n'
main(data)
CAN SOMEONE PLEASE CLEAN THIS UP?
