Hi,

I'm trying create a parser for firepad history(using python), but I can't understand how works TextOperation. Someone can explain me how it works or show me where I can find a documentation about this?

If it's helpful, somebody has written a ruby script to do that.

Hi Michael,

thanks, I saw this script, but I didn't understand the method 'apply'. The argument for this method is a string, but in my case I would like a parse for firepad history json.

This json[1] is the common format for json history on firepad?

There is no method 'apply' in that script. :-)

It's true, sorry, I confused with the oldest ruby script[1].

The algorithm used in this ruby[2] script is almost the same of my implementation in python[3], but I'm not sure if this code will cover all cases. This is the reason that I want to know if there is a documentation that describe this JSON format to confirm if my sample[4] is valid.

I don't know if this format is the pattern used with ACE editor or if is the official firepad json format.
