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

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

0.0.18

0.0.18 - 2023-10-10

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.
• &n is no longer a system function and is now called now
• under ⍜ now can be used to time things
• call ! can now call functions that return any number of values, not just one
• Add hex character escape sequences for string and character literals.
  • \xNN for short ASCII codes
  • \uNNNN for full Unicode sequences

Interpreter

• The formatter now aligns consecutive end-of-line comments
• NaNs no longer propogate in min ⌊ and max ⌈
• Fix a bug that prevented under ⍜ multidimensional take ↙ and drop ↘ from working
• Fix a bug in how fold ∧ ordered multiple accumulators
• Fix a bug that allowed incorrect signatures to be declared for functions
• Fix a bunch of other bugs and crashes

0.0.17

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
• Add a advice diagnostic about the captialization of binding names

Interpreter

• A few performance improvements, particularly to keep ▽, fork ⊃, and under ⍜
