'''ngn/k''' is an implementation of [[K6]] created by [[ngn]]
ngn/k has undergone several rewrites, borrowing ideas from many [[Arthur Whitney]] Ks, and occasionally deviating from their functionality.
ngn/k is written in [[Arthur_Whitney#Programming_Style|Whitney-style C]], and is written to be performant, compact, and with minimal dependencies.▼

== History ==
Line 36 ⟶ 38:
The current version of ngn/k resides in Codeberg, and the move was officially announced on May 21, 2021<ref>https://chat.stackexchange.com/transcript/message/57843141#57843141</ref>. The codeberg repository has its initial commit at 2019, where it had support for x86_64 linux only.
ngn/k was indefinitely frozen<ref>https://codeberg.org/ngn/k/commit/7e7420217f9df95273a8605e05d6335d66dd8f8a</ref> on May 24, 2022.
In January 2024, ngn/k was announced to be no longer supported.
== Running ==
Line 43 ⟶ 49:
[[User:Traws|Traws]] has a fork of ngn/k on [https://github.com/traws0/ngnk-windows Github] which is made for compilation under cosmopolitan libc.
== Features ==
=== I/O Verbs ===
ngn/k's I/O verbs are defined as per the [[K6]] standard. They are made up of a single digit, followed by a <code>:</code> symbol: <code>loc u: data</code> for output and <code>u: loc</code> for input.
A symbol, string or number can be given as <Code>loc</code>. Any number given must be a valid tie number (see: [[Tie(ngn/k)]]).
Every input verb is classified by <code>data</code>:
* <code>0:</code> takes lists of strings. (concatenates them with newlines)
* <Code>1:</code> takes a single string.
=== Reserved Symbols ===
ngn/k has reserved symbols used for providing access to features that are not important enough to be added as primitives, but still warrant a name for quick use. These symbols can be used like any other nouns.
The ngn/k help topic for adverbs is available at <code>\`</code> in the ngn/k repl.
=== Defined Verbs ===
ngn/k allows creation of new verbs that can be used infix, as part of its syntax. These must be defined as follows (using <code>∇</code> as an example symbol):
<pre>(∇:): monad
(∇): dyad</pre>
