Ngn/apl: Difference between revisions

ngn/apl supports most of the core language of [[Dyalog APL 14.0]],: [[dfn]]s (<syntaxhighlight lang=apl inline>{⍺ ⍵}</syntaxhighlight>), [[nested array]]s, [[complex number]]s (<syntaxhighlight lang=apl inline>1j2</syntaxhighlight>), [[Function train|forks and atops]], [[Multiple assignment|strand assignment]] (<syntaxhighlight lang=apl inline>(a b)←c</syntaxhighlight>), [[indexed assignment]] (<syntaxhighlight lang=apl inline>a[b]←c</syntaxhighlight>), and [[dop|user-defined operators]] (<syntaxhighlight lang=apl inline>{⍺⍺ ⍵⍵}</syntaxhighlight>), but does not support [[Key]] (<syntaxhighlight lang=apl inline>⌸</syntaxhighlight>), [[Rank (operator)|Rank (operator]] (<syntaxhighlight lang=apl inline>⍤</syntaxhighlight>) [[tradfn]]s (<syntaxhighlight lang=apl inline>∇R←X f Y</syntaxhighlight>), non-zero [[index origin]] (<syntaxhighlight lang=apl inline>⎕IO←1</syntaxhighlight>), [[comparison tolerance]] (<syntaxhighlight lang=apl inline>⎕CT</syntaxhighlight>), [[prototype]]s (it always uses zero as fill), [[modified assignment]] (<syntaxhighlight lang=apl inline>x+←1</syntaxhighlight>), [[keyword]]s (<syntaxhighlight lang=apl inline>:If</syntaxhighlight>), [[object-oriented programming]], or [[namespace]]s. It extends Dyalog APL with [[Infinity|infinities]] (<syntaxhighlight lang=apl inline>¯</syntaxhighlight> or <syntaxhighlight lang=apl inline>∞</syntaxhighlight>) and a few additoinal primitives.
