V 0.2.2

22 Jan 2021

vweb now uses struct embedding: app.vweb.text('hello') => app.text('hello').
Consts can now be declared outside of const ( ... ) blocks: const x = 0.
Overloading of >, <, !=, ==, <= and >= operators.
New struct updating syntax: User{ ...u, name: 'new' } to replace { u | name: 'new' }.
byte.str() has been fixed and works like with all other numbers. byte.ascii_str() has been added.
Smart cast in for loops: for mut x is string {}.
[noinit] struct attribute to disallow direct struct initialization with Foo{}.
Array decompose: [1, 2, 3]... is now ...[1, 2, 3]
Treating enum as int and operations on enum except == and != are removed for strict type checking.
Support [manualfree] fn f1(){} and [manualfree] module m1, for functions doing their own memory management.
Allow usage of < and > operators for struct in .sort method for arrays, i.e. arr.sort(a < b).
Auto generate assignment operators like +=, -=, *=, /= and %= if the operators are defined.
Colorize and improve failing tests output.
Fix go with a generic function: go test<string>(c, 'abcd').
Add comptime x := $embed_file('v.png') println(x.len) println(ptr_str(x.data())), for embedding files into binaries.
Advanced vdoc search on mobile layout.
string's left()/right were removed in favor of slicing syntax: str[..pos].
gg: native graphics mode on macOS/iOS (using Cocoa Drawing API).
