| # The main() function has been replaced by a whole class, in order to |
| # address the constraint that only one process can sit on the port |
| # hard-coded into the loader. |
| |
| # It attempts to load the RPC protocol server and publish itself. If |
| # that fails, it assumes that some other copy of IDLE is already running |
| # on the port and attempts to contact it. It then uses the RPC mechanism |
| # to ask that copy to do whatever it was instructed (via the command |
| # line) to do. (Think netscape -remote). The handling of command line |
| # arguments for remotes is still very incomplete. |
| |
| # Default behavior (no command line options) is to open an editor window |
| # instead of starting the Python Shell. However, if called as |
| # Pyshell.main(0), the Shell will be started instead of the editor window. |
| |
| # In the default editor mode, if files are specified, they are opened. |
| |
| # If any command line options are specified, a shell does appear, and if |
| # the -e option is used, both a shell and an editor window open. |
