If you are reading this on the website, then these changes are live here.

Crate

0.0.22 - 2023-10-21

Language

  • Custom modifier placeholders (^) must now be immediately followed by a signature. This reduces the number of signatures that have to be declared everywhere else.

0.0.21 - 2023-10-21

Language

  • Massive Change - Functions are no longer first-class values. This has many implications:
    • Functions can no longer be put in arrays or manipulated as stack values
    • Inline functions can now only appear as modifier arguments or bindings
    • call ! has been removed, as there is nothing on the stack to call
    • Modules have been reworked. &i now handles both loading a module from a file and importing items from that module.
    • --- scopes are now test scopes. ~~~ scopes have been removed.
    • Remove use, as it is no longer necessary
    • Boxes still work as normal, but are now their own type distinct from functions
    • Remove sig, as everything that can be on the stack now has the same signature
  • Add new syntax for defining custom modifiers
  • Add new syntax for calling a function from a list of functions
  • Add the pack ⊐ modifier, which calls its function and implicitly boxes/unboxes values
  • Add the combinate ◳ modifier, which is a rank-generic version of table ⊞
  • fold ∧ is now rank-generic and requires a rank list
  • Add the tribute ≐ modifier, which is a flipped version of distribute ∺
  • Change level ≑'s glyph to reflect its relationship with each ∵, rows ≡, distribute ∺, and tribute ≐. Code using ⍚ will continue to work and will be formatted as ≑.
  • Add rock ⋄, surface ~, deep ≊, abyss ≃, and seabed ∸, which build rank lists to be used with level ≑ and the new rank-generic modifiers
  • Change trace ⸮'s glyph to let surface ~ use ~.
  • Change match ≍'s glyph to avoid confusion with the new ocean functions' glyphs. Code using ≅ will continue to work and will be formatted as ≍.
  • Stack signatures found to be incorrect at runtime produce an error
  • Dyadic math operations now work with under ⍜ even if both arguments are outside under ⍜'s function
  • Some mathematical functions that previously did not work with invert ⍘ and under ⍜ when accompanied by flip ∶ now do

0.0.20 - 2023-10-16

Language

  • Add regex function for matching regular expressions
  • Add utf function for UTF-8 encoding and decoding
  • Add &invk system function for invoking a path to be opened with the system's default program
  • fill ⬚ can now be used with first ⊢
  • Most functions that expect strings as arguments will now dig arbitrarily deep into boxes
  • Make if ? signature checking more permissive
  • The presence of break ⎋ in a repeat ⍥ always requires a stack signature
  • The &runi and &runc functions now return exit codes
  • Multiline string now only insert \n at the end of each line instead of \r\n

Interpreter

Language

  • Major Change distribute ∺ now takes the array being distributed as its last argument, rather than its first
  • Add where ⊚ function, which returns the indices of an array that have non-zero values
  • if ?'s branches can now have a different number of arguments (but not outputs)
  • if ?'s condition can now be a list of conditions, and the branch will be chosen for each row in the argument(s)
  • The reducing versions of group ⊕ and partition ⊜ now take accumulators. Aggregating versions are unchanged.
  • spawn and wait no longer have glyphs. Code using ↰ and ↲ will continue to work and will be formatted as spawn and wait.

0.0.17 - 2023-10-07

Language

  • Add GIF encoding with &gife
  • Rename constant to box □.
  • Add unbox ⊔, which unboxes a boxed array
  • Major Change: Some uses of call ! will no longer compile without declaring a stack signature. When unboxing box □ed arrays, you can use unbox ⊔ instead, which has a well-defined signature.
  • Add fall ⍖ function, which gives the indices of the array if it were sorted descending
  • Change grade ⌂ name and glyph to rise ⍏ to reflect its relationship with fall ⍖. Code using ⌂ will continue to work and will be formatted as ⍏.
  • try ⍣ now puts arguments to its first function above the error value when calling the error handler
  • fold ∧ can now use multiple accumulators
  • Improve dump output formatting
  • dump is now a monadic modifier. Its function preprocesses each value before dumping it.
  • Add the sig function, which returns the stack signature of a value
  • A negative dimensions in the shape passed to reshape ↯ can now be in any position, not just the first or last
  • Functions with ASCII glyphs now also format from their names

Website

  • Execution time limit is now 2 seconds by default but can be customized

0.0.16 - 2023-10-05

Interpreter

  • Fix a crash and a bug that could occur when creating nested arrays that pull in values.

0.0.15 - 2023-10-05

This version changes a lot of glyphs. If you are coming from the previous version, most of the old glyphs will be automatically formatted to the new ones. The only change you may need to make is replacing all ^s with |s.

You may want to read the new version of the Advanced Stack Manipulation Tutorial to understand the reason for so many of these changes.

Language

  • Add the bracket ⊓ modifier, which calls two functions each on different arguments
  • Change fill ⬚'s glyph to reflect its relationship with box □. Code using ⍛ with continue to work and will be formatted as ⬚.
  • Change share ⇉ name and glyph to fork ⊃. Code using ⇉ will continue to work and will be formatted as ⊃.
  • Change noop · name and glyphs to identity ∘ to reflect its relationship with gap ⋅ and dip ⊙. Code using · will continue to work and will be formatted as ∘.
  • Change identity ∘'s signature from |0.0 to |1.1
  • Add the gap ⋅ modifier, which discards a value then calls its function. It is mainly intended to be used with fork ⊃.
  • Change dip ⊙'s glyph to reflect its relationship with gap ⋅ and identity ∘. Code using → will continue to work and will be formatted as ⊙.
  • Change both ∩'s glyph to reflect its relationship with fork ⊃. Code using ∷ will continue to work and will be formatted as ∩.
  • distribute ∺ now works with any number of arguments. Only the first argument is distributed.
  • fill ⬚ now works with reshape ↯
  • reshape ↯ now allow negative numbers to denote derived dimensions
  • Change the modifier termination character to | instead of ^
  • Remove old versions of fork and trident
  • Add the &httpsw function for making HTTPS requests

Interpreter

  • Add formatter configuration options. See the readme for details.
  • Checking for updates is less zealous, and can be disabled with the --no-update flag to uiua run or uiua watch

Website

  • Running code in the Pad editor updates the URL to prevent work from accidentally being lost

Pre-Version Updates

2023-10-03

Language

  • Add the share ⊃ modifier, which unifies and deprecates fork ⊃ and trident ∋
  • [bind '] no longer calls its functions immediately. This should not change any reasonable existing code.
  • Change how partition ⊜ and group ⊕ work with dyadic functions to be consistent with reduce /
  • Deprecate restack ⇵. It was never a good idea.
  • Remove the overloaded behavior of call !. It no longer behaves like an if-else when used with a list of functions.

  • Add the if ? modifier, which calls one of two functions based on a condition
