0.10.0 - 2024-04-04

You can find the release announcement here.

Language

• Breaking Change - Multiline strings are now also raw strings which do not require escaping
  • They are no longer format strings by default
  • Raw strings can be made format strings with an extra $, i.e. $$ …
• Breaking Change - try ⍣'s handler function is now passed the original arguments before the error
• try ⍣ now works with function packs of more than 2 functions
  • This tries each function in the pack in order
• Switch functions now format to use ⟨⟩ brackets
  • This makes them easier to identify when reading
  • It also allows switch functions to be used as modifier arguments without extra nesting
• Switch functions now work with under ⍜
• Add pattern matching with un °
  • Constant values can now be inverted to form a function which errors if the top value on the stack does not match
  • Format strings can be inverted to extract substrings
  • Read more in the new Pattern Matching tutorial
• Git modules are no longer experimental
  • Modules are added automatically as Git submodules when imported
  • See the Modules tutorial for more information
• map and related functions insert, has, get, and remove are no longer experimental
• Add the mask ⦷ function, which creates a mask of occurrences of one array in another
  • This works similarly to find ⌕, but is better when you need a mask or to distinguish between adjacent occurrences
• Change sine ∿'s glyph
  • ∿ is more representative of what it does
  • Most circle glyphs like ○ are used for array functions or stack manipulation
  • ○ will continue to work and will be formatted as ∿
• under ⍜ join ⊂ now works with arrays of the same rank as long as the row count does not change
• un ° scan \\ now works with equals = and not equals ≠
• group ⊕ can now take multidimensional index arrays
• partition ⊜ can now take multidimensional marker arrays
• under ⍜ select ⊏ and pick ⊡ now work with duplicate indices if the values at those indices are the same
• rotate ↻ now works through boxes
• fold ∧ now works with under ⍜ if its function does
• inventory ⍚ can now take 3 or more arrays
• repeat ⍥ can now take non-scalar repetition counts
  • This repeats the function a different number of times for each row of the inputs
• select ⊏ can now be used with un ° to separate into classify ⊛ and deduplicate ◴
• Characters can now be multiply ×d or divide ÷d by numbers to possibly toggle their case
• Add the csv function, which encodes and decodes CSV data
• Add the &clget and &clset system functions, which allow copying and pasting text to and from the system clipboard
• Add more shadowable constants
• Importing modules that use the # Experimental! comment now requires the # Experimental! comment in the importing file
• Doc comments may now be placed at the end of single-line functions
• Non-alphabetic identifiers can now be suffixed with ! to make macros
• Add df, ddf, etc shortcuts for dip ⊙ fix ¤
• Existing macros are now called "stack macros" to distinguish them from the new "array macros"
  • Stack macros are now hygienic
• Add array macros, which allow code to be generated and manipulated at compile time as strings
  • These are specified with a ^ immediately following a binding's arrow
  • They are documented in the Macros tutorial
• un ° pop ◌ can now be used to retrieve the fill ⬚ value
  • See more details in fill ⬚'s documentation
• Add the wildcard constant W, which matches any number, and @\W, which matches any character
  • These work well with match ≍, find ⌕, and mask ⦷
• Add the experimental coordinate ⟔ function, which searches an array for a value and returns a multidimensional index
  • coordinate ⟔ is to pick ⊡ as indexof ⊗ is to select ⊏
• Experimental function strands now use the ‿ character, which formats from __
• Add the experimental by ⊸ modifier, which duplicates a function's last argument before calling it
• Add the experimental quote modifier, which converts a string to code at compile time
  • This is useful in array macros
• Add # No inline! semantic comment, which prevents a function and its callers from being inlined
  • This enables better stack traces on errors
• Deprecate bind
  • It undermines the priniciples of the language
  • It makes certain optimizations impossible
  • fill ⬚ and/or map can be used to achieve similar effects
• Deprecate deal
  • It is rarely used and easy to express with other functions
• Deprecate experimental shapes and types modifiers in favor of pattern matching
• Remove cross ⊠ for good
• Remove unpack ⊐ for good
• Remove rectify ⌅ for good
• Remove &i for good
• Make reduce / with a monadic function a hard error

Interpreter

• Code is now analyzed for purity
  • All pure top-level expressions will attempt to evaluate at compile time
  • All fragments of code that are pure and have a signature |0.n will be evaluated at compile time
• Add lots of LSP features
  • Find references
  • Rename is now cross-file
  • On-type formatting (can be toggled in settings)
  • Inlay hints (each can be toggled in settings)
    • Binding function signatures
    • Inline function signatures
    • Values of top-level expressions
  • Code actions
    • Macro expansion
    • Remove output comment
    • Convert between strand and array syntax
  • Completions
    • Shadowable constants
    • Module items when the module reference is partially typed
• Add the --file <file> option to the uiua repl command
  • This runs a file before starting the REPL
• Improve the supported binding type coverage of &ffi
• Add warnings for when a loop in an array may have a variable signature
• Various performance improvements
  • Optimize and multithread ⊞(/+×), which is a common component of matrix multiplication
• Lots of bug and crash fixes
