Command line help is broken
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Command line help is broken for ParaView, especially on Windows. There really are three issues. - one Windows specific, the other two are general.
-
On Windows, a user should be able to open a Command Prompt, cd to the ParaView executable, and run paraview --help. This should show in the command prompt window OR in a window that opens up and stays open. Currently, help is written to a ParaView window, and immediately ParaView will close, also closing this help window.
-
The ParaView command line arguments are confusing. If an input does not have a command associated with it (such as -dr or --help), we assume it is a file. Thus, if you try to get help, and don't know the command, ParaView just assumes it is a file to open. It says no such file. For instance, 'paraview -h' will fail loading the -h file. Please change this to either always require a file command (maybe -f), or if the file is read in from the command line, and doesn't exist (or starts with a -), print out the command line help.
-
We are inconsistent with ParaView command line arguments. Help is the most obvious example. Please add a -h command for help.
