0.0.43

Hovering function calls will now show the actual value of default parameters instead of just *.

0.0.42

Misc bugfixes

0.0.40

Root path is determined relative to the mtots executable if one is found.

Fix minor race condition bug

0.0.39

Better goto-definition for module variables

0.0.38

Bugfix when resolving usage of qualified parameter types

Updated logic for finding modules (in particular, __init__ modules are now supported).

0.0.37

Hover to get information about a field over the definition of the field (methods already could do this, but fields have been overlooked up to this point)

isAssignableTo now takes into account inheritance

0.0.35

Untyped lists are shown as List instead of List[Any]

LiteralType.isAssignableTo() bugfix

Fixes hanging and out of memory issue due to an infinite loop in the parser.

Drop support for running this extension in the browser. Might be brought back at some point in the future, but it's quite a bit less convenient to debug, and I don't really have a use for this at the moment.

0.0.34

Support for decorator syntax

constexpressions can include constexpr variables from imported modules.

Another patch for the OOM issues with files that do not end in a newline. It seems this issue is still in the rewrite.

0.0.33

Large rewrite of the extension!

The parser and lexer are resued, but everything else, including the way the extension comes together, and the type solver have all been rewritten.

0.0.32

Short term fix for the hanging and crashing missing newline bug.

... But the issue still seems to persist.... Address this later at some point.

0.0.31

Web compatible - i.e. this extension should now be installable from vscode.dev

Parser errors are no longer fatal

NOTE: There is a performance bug that happens whenever any mtots file does not end in a newline and causes a crash. Right now I have no idea why this is the case, and I don't quite have the bandwidth to explore this right now.

0.0.29

Names that start with _ will appear after names that do not start with _.

List.__add__(), List.extend(), List.reverse() methods

List(), Dict(), Dict.fromPairs()

Tuple

Hover will now distinguish between whether the symbol usage appears in a value context or a type context.

FrozenList.

New style Tuples.

String.upper() and String.lower() methods.

0.0.31

String.startsWith and String.endsWith methods.

String.__iter__()

0.0.30

Lambda expression syntax

0.0.29

...

0.0.28

Support for trait fields

Fix autocomplete bug

Support for the ternary conditional operator (i.e. if-then expressions).

trait interface methods and fields bugfix

0.0.27

Fix placement of docs for variable (comes after type, rather than before)

List.clear() method

**/__pow__ operator support

__slice__ syntax support

Syntax highlighting for binary number literals

Variable documentation being placed above the declaration is no longer supported. Variable documentation must now come after the name (or type annotation if present) and before the = symbol.

Number.toU32

0.0.26

Fix a bug in the type solver related to the Iteration type

0.0.25

Bitwise operators for numbers

Iterable based on whether __iter__ method is implemented for custom types

Better hover comment for constructor calls

0.0.24

Support for adding documentation to fields.

Support for adding documentation to variables after the name.

0.0.23

List.flatten

StringBuilder

raise syntax and documentation for variables

0.0.5

Bugfix for when modules cannot be found.

0.0.4

Actual smart language features! Diagnostics, goto-definition, auto-completes based on variables in scope and members available for a given value; parameter hints.

Likely still lots of bugs that need to be squashed. Will address them as I use this extension and find them.
