0.9.0

0.9.0 - 2024-02-25

Language

• Breaking Change - repeat ⍥ with infinity ∞ now does a fixed-point iteration rather than an infinite loop
  • You can still do an infinite loop with do ⍢(…)1
• Breaking Change - reshape ↯ with a shape with negative dimensions now reverses that axis rather than acting as a "fill" value
  • The "fill" behavior can still be achieved by setting an axis to infinity ∞
• Breaking Change - &ad and &imd now return an encoding format as a string in addition to the media data
  • They are also now deprecated in favor of using un ° with &ae or &ime
• Overhaul the module system
  • Details can be found in the updated Modules tutorial
  • Deprecate &i, as it is no longer necessary
  • Enabling experimental allows a module path of the form git: <repo url> to load a module from a git repository
• Custom modifiers are now called "macros"
  • Rather than requiring signatures, placeholders are now a sort of function that operates on the macro's arguments
  • This allows for more complex and flexible code-reuse
  • Existing code should continue to work. Existing placeholders will be formatted into the new syntax.
  • You can read more about macros in the updated Macros tutorial
• Add the on ⟜ modifier, which captures a common fork ⊃ pattern in a more readable way
• join ⊂ can now be used with under ⍜
  • This only works when the joined arrays have different ranks
• join ⊂ can now be used with un ° to separate the first row of an array from the rest
• try ⍣'s handler's function signature is now more flexible
  • This makes it easier to either provide a default value, process the error itself, or do something different with the inputs
• A fill ⬚ value set outside a looping modifier will now no longer be available inside the loop
  • This should make it easier to scope fill ⬚ correctly
• fill ⬚ can now match the lengths of inputs to rows ≡
• Add recursion via refering to a binding's name within its body
  • Deprecate this ↬ and recur ↫, as they are no longer necessary
• Extend some math functions to work with characters
  • sign ± gets the case of a character
  • absolute value ⌵ uppercases a character
  • negate ¯ toggles the case of a character
• range ⇡ can now be used with negative numbers
• eta η, pi π, tau τ and infinity ∞ are now parsed as numbers rather than functions
  • This lets them syntactically bind with ¯ or form fraction literals
• Add the inventory ⍚ modifier, which iterates over the unboxed items of an array and re-boxes the results
  • This shortens a lot of box array code
• Change content ◇'s glyph to reflect its relationship with inventory ⍚. Code using ⊔ will continue to work and will be formatted as ◇.
• content ◇ can now be used with under ⍜ if its function does
• Macros with 2 or more arguments can now use ‼ at the end of their names. Macro names with any combination of ! and ‼ will be automatically parsed and formatted as ‼s followed by one ! if necessary.
• f can now be used at the beginning of planet notation shorthand for fork ⊃
• Inline functions are no longer required to be in a binding or modifier
  • This allows arbitrary code to be wrapped and marked with a signature
• Remove cosine and arccosine optimizations
  • The inverse of the cosine idiom created a logical inconsistency
• pop ◌ can now be used with under ⍜
  • This is only useful when pop ◌ is composed with other functions
• Breaking Change - Flip the order of send's arguments
• Add the pool modifier, which is identical to spawn but spawns a thread in a thread pool
• &rs can now take a count of infinity ∞ to read until the end of the stream
• Add the &runs system function, which runs a command and returns an IO stream handle
• Add the experimental stringify modifier, which turns its function into a string without calling it
  • This is useful in macros
• Add the experimental signature modifier, which returns the arguments and output of its function without calling it
  • This is useful in macros
• Add the experimental &ffi system function, which allows calling functions from shared libraries
  • FFI is still a work in progress, but it is currently useful for foreign functions that aren't too complex
  • Bindings for Raylib are being worked on as a proof of concept. You can find them in the rayua repository.
• Add experimental function strands. Putting a _ between two functions (or a function and a constant), is equivalent to putting them in ()s
  • This is experimental because it remains to be seen how this may affect readability
• Add experimental labels, denoted by a $ immediately followed by an identifier, which attach a name to an array. This has two uses:
  • Labels are visible in output and in stack diagnostics
  • Labels in code make it easier to understand when reading
• Add experimental shapes and types modifiers, which validate the shape and type of an array or arrays
  • These both check array properties at runtime and serve as a form of documentation
• &var now throws an error if the variable is not found
• Deprecate pop ◌ formatting from ;
• Deprecate all ⋔
  • It was rarely used and was hard to reason about
• Add an experimental repr function that produces a string representation of a value in a format that can be read by the interpreter

Interpreter

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

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 ⊏
