k, i thought that there might be something like this going on. you
need to use MSyntax and MArgParser parse flags for your command. you
cannot parse the flags yourself if you want the command to work both
in MEL and python.

maya does not understand my "p" flag
same command using mel :
cacheDeform -ts -p "c:/teste";
// Successfully wrote deform cache file for all objects //
.. tnxs again for help me !

i wonder if there is some strange code in the plugin regarding a
result set by MPxCommand.setResult() that works in MEL but cannot be
converted into a python object by mel.eval?
but still, why not call this command from maya.cmds as chris
suggested?
maya.cmds.cacheDeform(ts=True, p="c:/teste")

Tnx folks for help me unhappy the problem isn`t the "/"character
nor the single quoting
another test with the suggestions
#
doCreateCacheCommand = 'cacheDeform -ts -p "c:/teste"'
mm.eval(doCreateCacheCommand)
#maya return
mm.eval(doCreateCacheCommand)
// Successfully wrote deform cache file for all objects //
# Error: Error occurred during execution of MEL script

again the plugin works but after end its functions . maya return a
error !

The single/double quoting could do the job, but in my local test
the escape character "\" works.
//MEL
global proc createSphere(string $name){
sphere -n $name;
}
#PYTHON
import maya.mel as mel
cmd = "createSphere \"test\""
mel.eval(cmd)
I tested this with a simple function - perhaps custom commands with
flags work differently...

in python strings the \ character represents a continue line
(meaning: the string is continued on the next line)
when making a command string in python you can write it this way
doCreateCacheCommand = 'cacheDeform -ts -p "c:/teste";'
the string is wrapped in single quotes with double quotes inside
the string not being evaluated util eval call is made on them
I can not test if this is your fix but it looks like it

I got some problems when I call Mel commands from Python . always I
got some return error
some examples :
import maya.mel as mm
doCreateCacheCommand="cacheDeform -ts -p \"c:/teste\" "
mm.eval(doCreateCacheCommand)
// Successfully wrote deform cache file for all objects //
# Error: Error occurred during execution of MEL script
# Traceback (most recent call last):
# File "<maya console>", line 3, in <module>
# RuntimeError: Error occurred during execution of MEL script #
this plugin is wrote using c++ API e create "cacheDeform" mel command
when it is called using python it works well , but after it ends
its functions I`ve got a RuntimeError
as you can see in :
// Successfully wrote deform cache file for all objects //
the plugin is working
when a call it usin only MEL I got no return error
cacheDeform -ts -p "c:/teste";
// Successfully wrote deform cache file for all objects //
I have another question . is it possible create python commands using
API Mfn instead mel commands ?
