Couple of automation questions

[C K Kashyap]

Hi,

I have a situation where I need to "beautify" a log file quite often. I need to do the same set of steps.

What is the recommended best practices for the following approaches - 

1. Keyboard Macro

What is the way to save the macro to disk? Do we open a new buffer (or a buffer that contains all keyboard macros) and then insert it there and save it?

2. Scripting

Whats the recommended way to get started with scripting? Do I open up a buffer and start typing? I dont seem to get function name completion in a new buffer.

Regards,

Kashyap
