|

-c cmd run the command in a shell
|
||||
-d enable the debugger
|

-e edit mode; arguments are files to be edited
|
||||
-i open an interactive shell
|
||||
-i file(s) open a shell and also an editor window for each file
|
||||
-r
|
||||
-s run $IDLESTARTUP or $PYTHONSTARTUP before anything else
|
||||
-t title set title of shell window
|
||||
The following options will override the IDLE 'settings' configuration:
|
||||
|
||||
Remaining arguments are applied to the command (-c) or script (-r).
|
||||
-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"
