hello:)

I would like to know if in a macro we can use the latex grammar to know for example if we are in an environment or in displaymath etc... to adapt the command to this situation ?

If I understand your question, then yes, that's what scope selectors are for.

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>" ------------------------------------------------
