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
