[TxMt] Latex grammar and snippet or command

[Brad Miller]

Alain,

Here is a command I wrote to run Python code that is in a lstlisting
environment.

Save: Nothing
Input: Selected Text or Scope
Output: show as tooltip
Scope: source.python
------------------------------------------------
#!/usr/bin/env python
import sys
import string


# find first non-blank line
# determine indent
# remove indent from rest of the lines.
# run the code using doctest

def allWhite(s):
    allWhite = True
    count = 0
    for ch in s:
        if ch not in string.whitespace:
            allWhite = False
            return count
        count += 1
    if allWhite == True:
        return -1

prog = sys.stdin.read()

lineList = prog.split('\n')
i = 0
nonWhite = allWhite(lineList[i])
while nonWhite < 0:
    i = i + 1
    nonWhite = allWhite(lineList[i])

for i in range(len(lineList)):
    lineList[i] = lineList[i][nonWhite:]

#print "<pre>"
#print "\n".join(lineList)
tester = """
def _test():
   import doctest
   doctest.testmod(verbose=True,optionflags=doctest.NORMALIZE_WHITESPACE)
_test()
"""
exec  "\n".join(lineList) + tester

#print "</pre>"
------------------------------------------------
