Objective-C basics

if type T is an NSObject descendant, then it will support these messages:

+ (T *)alloc;
- (T *)init:(T *)self;
- (void)release;
- (T *)retain;

Objects (technically, variables of type T * where T is class type) can be either owned or not.

also made Command a linear datatype (i.e., dataviewtype)

ATS sales pitch

Time well spent when programming

Audience: C/C++ programmers.

Improving correctness means less maintenance and more fun!

  • everybody want more features
  • but more features usually mean more bugs and failures
  • stuck fixing bugs? not a good use of your time!
  • yet software devs spend most of their time hunting for and fixing bugs

ATS/Postiats syntax hilighting support for the Monaco editor.

// ATS/Postiats lexical syntax definition
// Written by Artyom Shalkhakov over the week of 20th - 27th of June, 2016.

// TODO: staload and dynload are followed by a special kind of string literals
// with {$IDENTIFER} variables, and it also may make sense to highlight
// the punctuation (. and / and \) differently.
