Thanks, Peter.  These things may seem obvious to you, but it seemed a 
bit of an edge-case feature vis a vis others in the queue, so the 
background you provided is very helpful.


And thanks, David.

Thank you, Panos.

This item was particularly interesting:

   Add a new script library implementing unified diff generation and
   patch application: Expected in LiveCode 9.0 DP-7
   

It wasn't immediately clear to me from the notes in that PR what that
does, but the description sounds enticing.

Can you offer a little background on that?


It's exactly what it says on the tin: a library that implements an 
algorithm for finding a minimal line-based edit script between two input 
texts, along with the ability to turn that into a unified diff.


Go have a look at the source code, which contains inline documentation:
https://github.com/livecode/livecode/blob/develop/extensions/script-libraries/diff/diff.livecodescript

You could also have a look at the tests:
https://github.com/livecode/livecode/blob/develop/extensions/script-libraries/diff/test

Its development was sponsored by David Simpson.  Check out FMProMigrator. :)

Thank you, Panos.

This item was particularly interesting:

   Add a new script library implementing unified diff generation and
   patch application: Expected in LiveCode 9.0 DP-7
   

It wasn't immediately clear to me from the notes in that PR what that 
does, but the description sounds enticing.


Can you offer a little background on that?
