Improved stdlib, variadic functions, default parameters

Features

• Standard Library written in Aria.
• A whole set of runtime functions.
• Type hinting on function parameters and return type.
• Default value on function parameters.
• Type lock on variables.
• Shorthand assignment operators.
• is operator for type checking.
• as operator for type conversion.

Improvements

• Out of bounds string subscript returns nil.
• Cache imports for more efficient loading.
• Simplify how imports are parsed for better treatment as expressions.

Bug Fixes

• Unresolved module properties now report an error.
• Module functions would fail on subsequent calls.

Variadic functions, Nil type and many bug fixes

Features

• Variadic functions in the ...args form.
• New Nil data type.

Improvements

• Short circuit boolean AND and OR.
• Open functions scope to allow calling other functions.
• Pipe operator supports any data type.
• Dictionary keys can be of any data type.
• Return nil on inexistent dictionary keys instead of runtime error.
• Return nil on inexistent array keys instead of runtime error.
• Empty or placeholder array index assignment appends a value to the array.
• Division by zero triggers a runtime error.
• Arrays or dictionaries can be compared with comparison operators.

Bug Fixes

• Assignment would update the current block scope, but not the parent.
• Multiple calls on a function would carry over the scope.
• Return in for in loop wouldn't cause the loop to stop and return a value immediately.

Mutable values, atoms, pattern matching

Features

• var variable declaration for mutable values.
• Assignment operator = for mutable values.
• Atom data type.

Improvements

• Switch now supports any data type.
• Pattern matching for arrays in Switch.
• Negative index subscript for arrays and strings.

Closures, ternary operator

Features

• Support for closures.
• New ternary operator ?:

Improvements

• Modules are now pre-interpreted completely, to allow access of functions from other functions.

Arrow functions

Features

• New arrow function syntax: (x) -> x
• Add Dict.update library function.

Improvements

• Switch supports arrays, either fully or element matching.
• Handle break and continue in for in loop

File imports

Features

• Support source file imports with the import keyword.

String in Switch

Improvements

• Switch controls and cases can now match strings.

Bug Fixes

• Fix a regression with token location.

Pipe Operator

Features

• Pipe operator |>

Improvements

• Module properties interpretation is now cached for faster results.

Improved StdLib, recursion and more

Features

• A lot of functions added to the Standard Library, including map, filter and reduce.
• Support recursive function calls.
• Floats in scientific notation.
• Error reporters shows the character number too.

Bug Fixes

• Errors could cause an unusable repl.
• Sometimes the repl would panic and crash the program.
• Error reporting would sometime show the wrong line number.
