0.8.0

0.8.0 - 2024-01-31

Language

• Add the content ⊔ modifier, which unboxes its function's arguments before calling it
  • Deprecate unpack ⊐ in favor of content ⊔
  • The behavior of content ⊔ is less implicit and is not prone to some of the potential unexpected behavior of unpack ⊐
• Add the unique ◰ function, which creates a mask of the first occurrence of each unique value in an array
  • Change deduplicate ◴'s glyph to reflect its relationship with unique ◰. Code using ⊖ will continue to work and will be formatted as ◴.
• table ⊞ now works on rows of arrays but keeps it's optimizations for lists
  • You never wanted element-wise combinations of multi-dimensional arrays anyway
  • Deprecate cross ⊠, as it is now redundant
  • This is technically a breaking change, but it is unlikely to break much code
• fill ⬚ can now be used to specify default accumulators for reduce /, group ⊕, and partition ⊜
  • Breaking Change - Reducing group ⊕ and partition ⊜ no longer take a required accumulator
  • Breaking Change - fill ⬚ can no longer be temporarily disabled. Try to scope it to the smallest function.
• Breaking Change - Most non-pervasive monadic functions no longer implicitely unbox their argument
  • This impliciteness led to some unexpected behavior, particularly when getting the length ⧻ or shape △ of a boxed array
  • Exceptions are reverse ⇌ and transpose ⍉, which work on box elements without unboxing them
• Unicode escape sequences that are not 2 or 4 bytes long can now be specified with \u{…}
• Change pop ◌'s glyph to make it look good in planet notation. Code using ; will continue to work and will be formatted as ◌.
• un °reduce /multiply × now gives the prime factorization of a number
• classify ⊛ and deduplicate ◴ now work with under ⍜
• &fras and &frab now work with under ⍜
• Completely remove the deprecated unbox ⊔
• Add experimental hashmap functions, which operate on a box array as if it is a hashmap
  • map
  • has
  • get
  • insert
  • remove
• Add experimental bind modifier, which binds local values within a function
  • This introduces some non-tacitness to the language

Interpreter

• The internal byte array type is now used in more places, which should improve performance a bit
• &ime and &imd now support the QOI image format
• Lots of bug and crash fixes

Website

• Add a new tutorial: Thinking With Arrays

0.7.1

0.7.1 - 2023-12-18

Interpreter

• Fix some bugs and crashes

0.7.0

0.7.0 - 2023-12-15

Language

• An entire Uiua codebase is now compiled before it is executed, rather than compiling and executing line-by-line
• Add the memo modifier, which memoizes a function
• Add the comptime modifier, which runs a function at compile time
• &i can now only be used as the first function in a binding
• repeat ⍥ can no longer use a negative number of repetitions
• repeat ⍥ can now be used with un ° and under ⍜
• reshape ↯ now works with under ⍜
• scan \ now works with un ° in some cases
• setinv and setund are no longer experimental
• Add output comments, which the formatter fills with values from the stack
  • Make an empty comment starting with n additional #s
  • The formatter will replace the comment with the top n values from the stack
  • Output comments in functions will show a number of values present on the stack for each time the function is called

Interpreter

• LSP improvements
  • Add hover information on binding references
  • Add signatures to binding hover information
  • Add same-file binding rename support
  • Add same-file goto definition support
• Add the uiua build command, which emits a .uasm bytecode file
• uiua run can now run a .uasm bytecode file
• uiua stand now embeds the bytecode assembly in the executable
• Multiple compiler errors can now be emitted at once
• Bug and crash fixes
• Performance improvements

Website

• Add an Inverses tutorial
• Each tutorial challenge now contains 1 or 2 answers

0.6.1

0.6.1 - 2023-12-07

Interpreter

• Make proxy values a little less leaky
• Make placeholders work properly with both ∩
• Some other bug and crash fixes

0.6.0

0.6.0 - 2023-12-06

Language

• fix ¤ now works with binary pervasive functions
  • This removes the need for some uses of rows ≡ and should be a bit faster
• fill ⬚ can now be disabled for a function by filling with an empty list
• parse ⋕ now has a glyph and is semi-pervasive
  • It was being used enough to warrant a glyph
• sign ±, floor ⌊, ceiling ⌈, and round ⁅ now work with under ⍜
• Add some missing arithmetic inverses and unders involving flip :
• Change pack's name to unpack ⊐, and it no longer implicitly boxes values (only unboxes them)
  • Implicit boxing could lead to unexpected and inconsistent behavior
• Change invert's name and glyph to un °. Code using ⍘ will continue to work and will be formatted as °.
  • ° is a nicer glyph, and un composes more nicely with the names of invertible functions
• Deprecate unbox ⊔ in favor of un ° box □
  • It can still be typed the same way!
• Deprecate reduce / with a monadic function
  • This created poorly-defined stack signatures that changed depending on the length of the array being reduced
  • un ° with stack array and planet notations, i.e. °[⊙⊙∘], can be used instead, as it has a well-defined signature
  • For operating on just part of an array, use under ⍜ take ↙, drop ↘, or select ⊏
• box □ed arrays can once again be compared lexicographically

Interpreter

• Make stack ? and dump output show call stack
• Show type and shape information when pretty-printing empty arrays with rank 2 or greater
• Improve language server hover information
• Bug and crash fixes

Website

• Add a token count to the editor (in settings)
• Files can now be dragged into the editor to open them with &fras

• dump now works with invert ⍘ and under ⍜
