CSC151 Class 34: Script-Fu, the Gimp's Scheme-Like 
  Programming Language

Overview:
* Quick intro to Script-Fu
* Lab
* Reflection

Notes:
* Happy April Fools' Day
* Are there questions on exam 2? 
* No reading tonight (but think about Script-Fu)

----------------------------------------

A: What happens if I write a solution that works for most cases,
   but not all cases?
Q: It depends on what mood I'm in and the overall structure
   of your answer.
Q: Why don't you show me your answer in advance!

----------------------------------------

Theory: Every large program needs its own programming language.
* Help with "annoying repetitive tasks"
* Easier for things that need precise computation

The Gimp's first programming language was (and is) "Script-Fu"
  Mostly based on SIOD, a variant of Scheme
  A lot like DrScheme except ...
    Unfriendlier errors
    Fewer built-in operations
    Lots and lots of graphics operations

Lab: Learn simple aspects; Think about reflection questions

----------------------------------------

Reflection Questions:
* What was your favorite part of today's lab?
* What was your least favorite part of today's lab?
* What advantages, if any, are there from being able to write
  Script-Fu commands for the Gimp?
  + You can be very precise
  + Dynamically generate images (e.g., for Web services)
  + Easy to mess with pictures
* What else would you like to learn about Script-Fu?
