Compare and print altered text

[Akira]

Hey,

 

I am building some sort of wiki page which has a lot of text on each page.

 

Now multiple people are editing this wiki page, and if person A is editing I would like to send person B and C an email with the part of the text which has been edited.

 

Any idea's on how to work this out?

 

Regards, Maarten

Could just add into the script to send emails automatically every time it's uploaded to all the contributors of the page (although this could get quite annoying on a contributor end so build in a flag that says yes notify... or no don't).

Thanks for the reply!

 

Already doing that, but as the pages on the wiki are growing, it's hard to see the text which has been updated. Thats the problem

Oh you just want to send the text that was updated only? Sorry, about that misread that I think. Let me know if that's right?

Could do a script comparing the the old one before it was updated and the new one. A scan of text of the old copy comparing to the new one noting the additions/changes at each point... hmmm theoretically this seems simple but the more I think of how to accomplish this after it finds the first change and continues has me baffled... maybe someone else has an idea

 

 

EDIT:  Here's a class I came across that compares lines, not sure how well it'll work but maybe you can modify it for your needs.

haha that was my first reaction as well, simply compare the to text and output and email the changes.. but the more you think about it, the tougher it gets thanks for the link though!  i'll have a look!
