APL Orchard: Difference between revisions

'''The APL Orchard''' ([https://apl.chat apl.chat]) is a [[wikipedia:Stack Exchange|Stack Exchange]] chat room dedicated to learn and teach APL, and to ask and answer questions about both golfing and general coding in APL. It was opened by [[Adám Brudzewsky]] on January 24, 2017, and has since developed its own community, remaining the most active APL chat room today, with over 1.000 messages per week. It passed a total of a 100.000 messages by 200 users in July 2020, and 150.000 messages by 250 users in February 2021. Code can be executed directly in the chat room.

Newly joined users always display a generic user name (like user1234567) and avatar until they've had some positive activity.

To reply to a specific message, hover over the message you want to reply to and click <kbd>↳</kbd> in the bottom-right corner of that message. This will insert a code similar to <code>:12345678</code> into the input field. Proceed to type your response and press enter or click <kbd>send</kbd> to send it. Note that replying to a message pings the user who wrote the message. <!-- To reply to users posting from IRC, via the chat bot, it is preferred to use <source lang=md inline>name:</source> instead of <code>@name</code>. Note that IRC users do not see edits, deletions, or formatting. -->

* {{Anchor|inline|'''Inline code:'''}} <source lang=md inline>`inline code`</source> <ref>Backticks can be escaped with a backslash (<source lang=md inline>`\`x\`y`</source> renders as <code>`x`y</code>). Alternatively, <code>```multiple``backticks\```</code>, which also disable <code>\</code>-escaping, can be used, giving <code>multiple``backticks\</code> - use a delimiter with one more backtick than the longest run of backticks in the code. Note that inline code cannot have leading white-space.</ref>

=== Multi-line messages ===

It's possible to insert line breaks in messages with <kbd>Shift</kbd>+<kbd>Enter</kbd>. Pasting test containing line breaks into the input field also results in a multi-line message. Multi-line messages do not support normal markdown.

If each line of a message is preceded by 4 spaces (which can be inserted automatically with with <kbd>Ctrl</kbd>+<kbd>k</kbd> or with the <kbd>fixed font</kbd> button once multiple lines have been entered), the whole message will appear in monospace font. Note that individual lines cannot be formatted this way, and that there is no support for "code fences" (triple backticks before and after code). Note that multi-line blocks cannot include a reply tag. Instead, one can begin with a leading reply message (which must contain something more than the reply tag), and then post a separate code block.

=== Executing code ===

The APL Orchard features two ways of executing code directly in the chat room, both based on [[TryAPL]]:

 

* [[TryAPL#Chatbot|A chatbot]] which responds to code in posted messages.

* [[TryAPL#Chat box exec|A userscript]] which evaluates code directly in the message input field.
