0.4.2

• Fixes a regression introduced in Pluto 0.4.1 that prevented the walrus operator from working within lambda functions that are passed as function arguments

0.4.1

• Updated lexer to tokenise in a separate pass
  • This fixes Pluto's error messages sometimes not showing the full line
• Disallowed use of the walrus operator within a function call because it was found to be more janky than expected

0.4.0

Additions:

• Walrus Operator
• Default parameters for functions.
• New standard library: lcryptlib, for various hash algorithms and cryptographic PRNGs.
• New warnings:
  • Unreachable code.
  • Too many function arguments.

Improvements:

• Switch case may now use variables.
• Shorthand ternary syntax from C/C++.
• Warnings can be configured with comments.
• Improved performance of some common arithmetic algorithms.
• VM Dumping has been rewritten for superb runtime detail on all opcodes, their arguments, their results, etc.
• string.upper & string.lower take a second parameter indicating a specific index to change. Absence of this parameter preserves default behavior.

0.3.2

Improvements:

• io.copyto will now overwrite existing files instead of throwing an exception.
• Improve error handling of other exception-prone IO functions.

0.3.1

Bugfix:

• String.split would previously invoke an infinite loop when an empty string is used as the delimiter.

0.3.0

Additions:

• Inlined method creation.
• STR in STR expressions.
• KEY in INDEXABLE expressions.
• Generalized iteration, no need for pairs.
• io.listdir
• Reserved keywords as valid fields.
• Null-coalescing operator (w/ compound operator).
• continue N & break N for manipulating outer loops.
• Optional type-hinting, with parser warnings.
• Safe accessor navigation, to avoid "attempt to index nil" errors for deeply nested fields.

Changes:

• table.contains now returns an index if found and nil otherwise (previously returned true or false).

Improvements:

• Switch no longer has syntactic restrictions
• Greater switch performance

Documentation for the new changes can be found here.
