APL Orchard: Difference between revisions

From October 18, 2017 until May 16 2018, Adám Brudzewsky ran a series of 29 live 90-minute study sessions which became known as ''APL Cultivation''. They cover most aspects of basic APL programming. Transcripts are available (see [[#External links]]).

The room features a chat bot which can evaluate single lines of APL. To use it, prefixed a chat message by <source lang=apl inline>⍞←</code>. Use <source lang=apl inline>⎕←</code> instead for boxed display and multi-line results and use <source lang=apl inline>⋄</code> instead to silence the first statement, after which subsequent statements must use <source lang=apl inline>⎕←</code> to output. Use <source lang=apl inline>]</code> to prefix user commands (without <source lang=apl inline>⎕←</code> or <source lang=apl inline>⍞←</code>), including e.g. <source lang=apl inline>]help ⍣</code> for help on the <source lang=apl inline>⍣</code> glyph etc. Do not use markdown, but fixed-width (4 or more initial spaces, which can be inserted by pressing <kbd>Ctrl</kbd>+<kbd>K</kbd>) is fine. This also ensures proper rendering with monospace font and avoids interpretation of APL symbols as markdown.

Only a few special [[system commands]] are available: <source lang=apl inline>)lb</code> for language bar, </code>)docs</code> for full documentation, <source lang=apl inline>)ref</code> for a link to the PDF reference card, <source lang=apl inline>)idioms</code> for a link to a searchable [[idiom|idiomatic expressions]] list.
