Post-Processing Script Parameters?

Version

Any, so far.

Operating system type + version

Windows 7 Pro

Behavior

I made a post-processing script which accepts parameters (like: Slic3rPostProcessing.exe --output "c:\GeeeeCode\[input_filename_base].gcode" --v 4 --i ) but for some reason, whenever I add such a parameter to the script input box it will fail to execute my script.

Error
---------------------------
The configured post-processing script is not executable: check permissions.
(c:\temp\Slic3rPostProcessing.exe --v 4 --i )
---------------------------
OK   
---------------------------

Is it not possible to pass parameters?

I met the problem too. My solution is to write a .bat file, e.g. postprocessing.bat and Slic3r will run the script with filename as the first parameter: postprocessing.bat <input_filename>. Then you can pass the filename to Slic3rPostProcessing.exe in postprocessing.bat. See my configuration: https://github.com/thuSkywalker/wiiboox-c300-slic3r-config/blob/master/gpx/gpx.bat

@thuSkywalker thank you! :-)

Actually, that limitation was in place on purpose, for security reasons. I didn't want people to be able to distribute a malicious config file containing, say, rm -rf ~/* thus executing arbitrary commands on other people's machines. Passing only the name of a single executable mitigates this risk. In order to supply arguments to a post-processing script, people could just create a wrapper shell script.

I wonder if we should add an option to enable this, and leave it disabled by default. I don't like the idea that Slic3r config files could be used as attack vectors.

I understand your concern. But do you have a means to pass parameters the save way?
As long as one can execute something, there's a risk of misuse. I could add that malicious command to my post-processor...

It looks like #4363 added the ability to pass parameters to a post-processing script. Is this issue still open because of the enable/disable feature?

Nah, I forgot about it and never closed it ... we're done here!
