Donna v0.3.0

Donna released v0.3.0 today. What this version brings to Donna?

Donna designed to be a small functional language that compiles to native binaries and focus on DX(Developer Experience).It's also statically typed and bootstrapped. In the past versions we focused to make the experience of using Donna better. We focused on a list of things that needed to refined. Let's take a brief look on those:

• Error messages.

Using donna revealed plenty of errors that happened because of linker failure that didn't help with further information. We tried to catch as many of those and create Donna errors that will contain more details.

• Type errors.

We improved type errors so users will have the info needed to debug their programs.

• Todo & Panic.

We implement todo and panic in the language. Todo used as a placeholder in a function that is not implemented yet. It raises a warning though, so users will have to return.

Panic crashes the program by throwing an error.

• We implement Opaque types correct behaviour. So far opaque types had the same functionality asa pub types and their constructors was accessible from other modules. Now they work as they supposed to.

• We implement error for duplicate function names

• echo now is for debug and will raise a warning. You should use new io module from stdlib:
  

io.println("hello")

• We improved error structure and style. We also added a summary of total errors and warnings.

We also fixed a lot of smaller bugs. Donna will keep evolving by focusing in users happiness. In the next versions we will focus on:

• Improve errors
• Fix bugs
• Improve formatter
• Start LSP implementation
