M idle M idle.py M idle.pyw M setup.py Switch back to installing IDLE as a package. The IDLE GUI and the subprocess will both attempt to start up via the package mechanism, but if IDLE is not yet installed it is possible to run by calling python idle.py in the IDLE source directory, or to add the source directory to sys.path. One advantage of doing it this way is IDLE stays off sys.path. Developed in collaboration with Tony Lownds.

USAGE: idle [-deis] [-t title] [file]*
|
|
idle [-ds] [-t title] (-c cmd | -r file) [arg]*
|
|
idle [-ds] [-t title] - [arg]*
|
|
|
|
-h print this help message and exit
|
|
|
|
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"
|
|
Open a shell window, run the script piped in, passing '' in sys.argv[0]
|
|
and "foobar" in sys.argv[1].

IDLE cannot run.

IDLE needs to use a specific TCP/IP port (8833) in order to execute and

debug programs. IDLE is unable to bind to this port, and so cannot
|
|
start. Here are some possible causes of this problem:
|
|
|
|
1. TCP/IP networking is not installed or not working on this computer
|
|
2. Another program is running that uses this port
|
|
3. Personal firewall software is preventing IDLE from using this port
|
|
|
|
IDLE makes and accepts connections only with this computer, and does not
|
|
communicate over the internet in any way. Its use of port 8833 should not
|
|
be a security risk on a single-user machine.
