Factor: contradictions?
|

|
|
-----------------------
|

|
|
|

|
|
Have our cake and eat it too
|

|
|
|

|
|
Research -vs- practical
|
||
|
|
High level -vs- fast
|
||
|
|
Interactive -vs- deployment

|
Factor from 10,000 feet
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
word: named function
|
||
|
|
vocabulary: module
|
||
|
|
quotation: anonymous function
|
||
|
|
classes, objects, etc.

The stack
|
||
|
|
---------
|
||
|
|
|
||
|
|
- Stack -vs- applicative
|
||
|
|
- Pass by reference, dynamically typed
|
||
|
|
- Stack languages: you can omit names where they're not needed
|
||
|
|
- More compositional style
|
||
|
|
- If you need to name things for clarity, you can:
|
||
|
|
lexical vars, dynamic vars, sequences, assocs, objects...
|
||
|
|
|
||
|
|

Object-oriented programming

|

Generic words: sort of like open classes
|

Tuple reshaping

Editing inspector

Meta programming
|
||
|
|
----------------
|
||
|
|
|
||
|
|
Simple, orthogonal core
|
||
|
|
|
||
|
|
Why use a stack at all?

|
|
Copy and paste factoring
|
||
|
|
Easy meta-programming
|
||
|
|
Sequence operations correspond to functional operations:
|
||
|
|
- curry is adding at the front
|
||
|
|
- compose is append

Written in Factor
|

|
|
renders with OpenGL
|
||
|
|
Windows, X11, Cocoa backends
|
||
|
|
You can call Windows, X11, Cocoa APIs directly
|
||
|
|
OpenGL 2.1 shaders, OpenAL 3D audio...

--------------
|
||
|
|
|
||
|
|
Two compilers

|
|
Generational garbage collector
|

C library interface
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Efficient
|
||
|
|
No need to write C code
|
||
|
|
Supports floats, structs, unions, ...
|
||
|
|
Function pointers, callbacks
|
||
|
|
Here is an example
|
||
|
|
|
||
|
|
TerminateProcess
|
||
|
|
|
||
|
|
process-handle TerminateProcess
