This mostly regards being primary-axis oriented, but also applies to making the original operators consistent and making `⎕IO←0` forced. The goal is to make APL more appealing to the modern audience. That is, to bring APL into its prime.\n\nRequires Dyalog APL version 17.1 or higher.\n\n### How to use\n\n#### Initialisation\n\nReplacing `ns` with your target namespace (e.g. `#`), do\n\n```\n]import ns path/prime\n```\n\n#### Running code\n\nNow you have three options:\n\n1. Use the extensions directly with the glyph names.\n1. Use `ns.prime.FIX` as a drop in for `⎕FIX`.\n1. Use `ns.prime.Repl ''` to start a (limited) self-contained session where the glyphs work. Enter `→` to exit.\n1. Use `ns.prime.Repl ref` to start a (limited) session in the namespace `ref`. Enter `→` to exit. \n\n### Breaking changes\n\n| Name                                              | Glyph  | Extension                                                    |\n| ------------------------------------------------- | :----: | ------------------------------------------------------------ |\n|[BackSlashBar](BackSlashBar.aplf)|`⍀`|only expand first|\n|[CircleBackSlash](CircleBackSlash.aplf)|`⍉`|monadic rotates axes|\n|[CircleBar](CircleBar.aplf)|`⊖`|disabled|\n|[CircleStile](CircleStile.aplf)|`⌽`|first axis|\n|[Comma](Comma.aplf)|`,`|first axis|\n|[CommaBar](CommaBar.aplf)|`⍪`|increase rank/join|\n|[DelStile](DelStile.aplf)|`⍒`|but dyadic sort-by|\n|[DeltaStile](DeltaStile.aplf)|`⍋`|but dyadic sort-by|\n|[DownArrow](DownArrow.aplf)|`↓`|enclose major cells|\n|[DownShoe](DownShoe.aplf)|`∪`|on major cells|\n|[DownTack](DownTack.aplf)|`⊤`|transposed and extend scalar|\n|[Epsilon](Epsilon.aplf)|`∊`|on major cells|\n|[Iota](Iota.aplf)|`⍳`|noticing 1-element vector|\n|[IotaUnderbar](IotaUnderbar.aplf)|`⍸`|`⎕IO←0` for monadic but `⎕IO←1` for dyadic|\n|[LeftShoe](LeftShoe.aplf)|`⊂`|just `⎕IO`|\n|[LeftShoeUnderbar](LeftShoeUnderbar.aplf)|`⊆`|on major cells|\n|[Plus](Plus.aplf)|`+`|purely numeric|\n|[QuadDivide](QuadDivide.aplf)|`⌹`|high rank|\n|[Query](Query.aplf)|`?`|high rank|\n|[RightShoe](RightShoe.aplf)|`⊃`|just `⎕IO`|\n|[SlashBar](SlashBar.aplf)|`⌿`|only replicate first|\n|[Squad](Squad.aplf)|`⌷`|but sane|\n|[Tilde](Tilde.aplf)|`~`|on major cells|\n|[UpShoe](UpShoe.aplf)|`∩`|on major cells|\n|[UpTack](UpTack.aplf)|`⊥`|transposed|\n|[\\_BackSlash](_BackSlash.aplo)|`\\`|scan first and outer product|\n|[\\_Diaeresis](_Diaeresis.aplo)|`¨`|handling empty arrays with failing prototype|\n|[\\_JotDiaeresis\\_](_JotDiaeresis_.aplo)|`⍤`|but handling empties|\n|[\\_Slash](_Slash.aplo)|`/`|only reduce first|\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fabrudz%2Fdyalog-apl-prime","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fabrudz%2Fdyalog-apl-prime","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fabrudz%2Fdyalog-apl-prime/lists"}
