Using ruby to find frames in a binary protocol and store each frame in an array -


I have a binary file, many of which are frames each frame starts with FF FF FF, after which - There is random data of different lengths. For example:

FF FF FF XX XX XX XX ... FF FF FAF XX XX XX XX XX XX FF FF FX XX XX XX ... .ff ff ff xx xx xx xx xx xx xx xx xx xx xx xx xx ........

It is safe to assume that FF FF Only random data as it will appear in the frame header part.

I am looking for a way to parse this binary file and remove each frame from the array using ruby.

Can anyone help?

For Ruby 1.8, you can simply split the input string on "\ xFF \ xFF \ xFF" Are there. The first entry will be before the first frame, and with such a format you can not know whether the last frame is full or not. They are quite simple, however, to remove: 

  input.split ("\ xFF \ xFF \ xFF") [1 ..- 2]

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors?

But I do not think the code is capable of changing the color of each variable declared....
