|

|
|
-h print this help message and exit
|
|
-n run IDLE without a subprocess (DEPRECATED,
|
|
see Help/IDLE Help for details)
|
|
|
|
The following options will override the IDLE 'settings' configuration:
|
|
|
|
-e open an edit window
|
|
-i open a shell window
|
|
|
|
The following options imply -i and will open a shell:
|
|
|
|
-c cmd run the command in a shell, or
|
|
-r file run script from file
|
|
|
|
-d enable the debugger
|
|
-s run $IDLESTARTUP or $PYTHONSTARTUP before anything else
|
|
-t title set title of shell window
|
|
|
|
A default edit window will be bypassed when -c, -r, or - are used.
|
|
|
|
[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].
|
|
|
|
Examples:
|
|
|
|
idle
|
|
Open an edit window or shell depending on IDLE's configuration.
|
|
|
|
idle foo.py foobar.py
|
|
Edit the files, also open a shell if configured to start with shell.
|
|
|
|
idle -est "Baz" foo.py
|
|
Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
|
|
window with the title "Baz".
|
|
|
|
idle -c "import sys; print(sys.argv)" "foo"
|
|
Open a shell window and run the command, passing "-c" in sys.argv[0]
|
|
and "foo" in sys.argv[1].
|
|
|
|
idle -d -s -r foo.py "Hello World"
|
|
Open a shell window, run a startup script, enable the debugger, and
|
|
run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
|
|
sys.argv[1].
|
|
|
|
echo "import sys; print(sys.argv)" | idle - "foobar"
