How to execute my script when save outline.leo

[翅膀]

i create a @button  node ,  and write some python script.  for example

```

n = c.find_h("some_node")[0]

open("xxx.md","wb").write(c.b.encode("utf-8"))

```

now i can click button to execute above script. 

But how can i config sth to automatically execute the scripte   when i save (ctrl+s)  the leo file.

Good question. I've waited until now so I could give a proper answer.

Recent revs document two new event handlers:

- after-reading-external-file

- before-writing-external-file

A plugin or script could register these handlers.

You could also use two other event handlers:

- save1  (before saving a .leo file)

- save 2 (after)

Finally, you might find these handlers useful:

- command1 (before executing any Leo command)

- command2 (after)

HTH.  Please feel free to ask other questions.
