Releases · uiua-lang/uiua

Breaking Change - minimum ↧ and maximum ↥ now compare boxes lexicographically
- This makes them consistent with comparison functions like less than <
Breaking Change - gen now takes a shape argument and no longer outputs a new seed
Breaking Change - &clip now unifies &clget and &clset
Breaking Change - type numbers are now:
- 0 for normal numbers
- 1 for characters
- 2 for boxes
- 3 for complex numbers
- This orders the types more or less as you're likely to need to handle them
- In the future, if another number type is added, it can go at the end next to complex numbers
The experimental chunks ⑄ function's behavior has been moved to an extension on windows ◫
- This also allows the specification of "stride"
- This is inspired by APL's stencil ⌺ behavior
- chunks ⑄ has been deprecated
Stabilize orient ⤸
- Change its glyph to something with broader font support
- ⮌ will continue to work and will be formatted as ⤸
Add anti ⌝ modifier, which simplifies choosing certain inverses
- Add related new anti ⌝ inverses for drop ↘, select ⊏, and pick ⊡ (though many more already existed)
Add obverse ⌅ modifier, which unifies the specification of inverses
- This unifies, replaces, and extends setinv and setund
- Deprecate setinv and setund
un ° by ⊸ can now be used to access the "undo" part of a function's under ⍜ functionality
Stabilize below ◡
Rename ⤙ but and ⤚ with to with ⤙ and off ⤚
- with ⤙ has been stabilized
"Stack macros" are now called "index macros"
- Stabilize existing placeholder indexing syntax (^0, ^1, etc.)
- Deprecate existing stack-based macro placeholders (^!, ^., etc.)
assert ⍤ at the beginning of a line is now interpreted as a test in some contexts
- See the updated Testing Tutorial for more information
parse ⋕ now parses complex values from both arbiand a+bi formats
- un °parse ⋕'s return value uses the arbi format
un ° orient ⤸ is now equivalent to range ⇡ length ⧻ shape △ duplicate .
- This is analogous to the behavior of un ° select ⊏
Add a feature to some under ⍜ functions that makes them more permissive of changes in rank
- Applies to select ⊏, keep ▽, first ⊢, first ⊢reverse ⇌
- The value that is "put back" can have its rank changed
- Lower rank arrays get repeated to match the original shape
- Higher rank arrays extend the length of the array
under ⍜ un ° bits ⋯ now preserves a minimum bit length
under ⍜ reverse ⇌, transpose ⍉, and rotate ↻ are now smarter with respect to the signature of under ⍜'s second function
- For example ⍜⇌°⊂ behaves in a more useful way
under ⍜ length ⧻ now reshapes an array to have the transformed length
NaN and ∞ indices for pick ⊡ and select ⊏ now get the fill ⬚ value
scan \\ now accepts functions that take more than 2 arguments
- The behavior is similar to the analogous behavior for reduce /
Allow on ⟜ to use function packs
Allow under ⍜ of scalar keep ▽
Add the graphemes function, which splits a string into unicode grapheme clusters
Add the &fmd system function, which creates a directory
Very large arrays are now displayed more concisely in output
Change and enhance the behavior of ; and ;;
- You can read about the new behavior here
Add unicode escape sequences for entering arbitrary characters
- A double backslash followed by a unicode hex number will format to the corresponding glyph
Add the timezone function, which gets the local timezone offset in hours
Scoped modules are now delimited by ┌─╴ and └─╴
- These both format from the existing --- delimiters
Add a Lorem constant, which contains the Lorem Ipsum text
Add several color constants
Add pride flag constants
Add Cats image constant
Allow &raw to be inverted, acting as a getter for the raw state of the terminal
- under ⍜&raw sets raw mode, and then returns it to the previous state
Experimentally allow fold ∧ to work with any signature
- Excess values are collected into arrays
Add the experimental around ’ function, which duplicates the top value on the stack to the third-to-top position
Add experimental tuples ⧅ modifier
- This unifies and extends the behavior of the choose and permute functions, which are now deprecated
- This also replaces and deprecates the triangle modifier
Add experimental base function
- This converts to and from base-N digits
Add an experimental sort ⍆ function
- Sorting is very common
- un ° sort ⍆ shuffles an array
Add an experimental last ⊣ function
- Getting the last row of an array is very common
Add experimental subscript modifiers
- They modify the behavior of some functions and modifiers
- You can read more about them here
Add experimental data definitions
- These allow for structured data similar to structs and enums in other languages
- They also allow a limited form of namable function arguments
- The experimental struct modifier/macro has been deprecated in favor of data definitions
Add the experimental layout function, which renders text into an image array
astar no longer errors if no paths are found
Remove previously deprecated function strands

Interpreter

Add the uiua find command, which finds Uiua code that matches the given unformatted text
Add the uiua doc command, which shows the documentation for a function or modifier
Add checking for end-of-line signature comments
- These are documented in the Documenting Code tutorial
Add webp support to img
Some optimizations
- Pervasive function machinery has been totally rewritten
  - Observed performance improvements of up to 12x
- fill ⬚ed array creation has been totally rewritten
  - Observed performance improvements:
    - ~1.2x in the best case
    - ~5x in the average case
    - ~450x in the worst case
- rows ≡ on ⟜/by ⊸ random ⚂/constant
- memberof ∈range ⇡ for scalar inputs to range ⇡
- memberof ∈rerank ☇1range ⇡ for rank 1 inputs to range ⇡
- first ⊢un °sort ⍆ to just pick an element
Tweak the formatter to reduce excess vertical space
The formatter now aligns consecutive single-line bindings
uiua repl now has a -s/--stack flag to disable clearing the stack after each line
- Clearing the stack is now the default
- The -c/--clear has been removed
After programs finish executing, the terminal raw mode will be automatically disabled if it was left on.
