2482 When you call
2483 \family typewriter
2484 %edit
2485 \family default
2486 with no arguments, IPython opens an empty editor with a temporary file,
2487 and it returns the contents of your editing session as a string variable.
2488 Thanks to IPython's output caching mechanism, this is automatically stored:
2489 \layout LyX-Code
2490
2491 In [1]: %edit
2492 \layout LyX-Code
2493
2494 IPython will make a temporary file named: /tmp/ipython_edit_yR-HCN.py
2495 \layout LyX-Code
2496
2497 Editing...
2498 done.
2499 Executing edited code...
2500 \layout LyX-Code
2501
2502 hello - this is a temporary file
2503 \layout LyX-Code
2504
2505 Out[1]: "print 'hello - this is a temporary file'
2506 \backslash
2507 n"
2508 \layout Standard
2509
2510 Now, if you call
2511 \family typewriter
2512 `%edit -p'
2513 \family default
2514 , IPython tries to open an editor with the same data as the last time you
2515 used
2516 \family typewriter
2517 %edit
2518 \family default
2519 .
2520 So if you haven't used
2521 \family typewriter
2522 %edit
2523 \family default
2524 in the meantime, this same contents will reopen; however, it will be done
2525 in a
2526 \emph on
2527 new file
2528 \emph default
2529 .
2530 This means that if you make changes and you later want to find an old version,
2531 you can always retrieve it by using its output number, via
2532 \family typewriter
2533 `%edit _NN'
2534 \family default
2535 , where
2536 \family typewriter
2537 NN
2538 \family default
2539 is the number of the output prompt.

2542 Continuing with the example above, this should illustrate this idea:
