The APL Orchard is a 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 began on January 24, 2017, and remains the most active APL chat room today, passing a hundred thousand messages and two hundred users in July, 2020.
While anyone can read the ongoing and past conversations, write access requires a Stack Exchange account and either 20 Stack Exchange reputation points or having been granted explicit write access by a moderator. The procedure for getting explicit write access is as follows:
- Go to the chat room
- Click the giant lower-left avatar
- Click "user profile"
- Copy the URL of the page that opens (e.g. "https://chat.stackexchange.com/users/123456/johndoe")
- Email that URL to email@example.com
The room features a chat bot which can evaluate safe APL. To use it, prefix a chat message, inline code, or a code block with
⋄. Using markdown (for example
`⋄ 2+3`) or fixed-width (4 or more initial spaces on each line, which can be inserted by pressing Ctrl+K) is recommended to ensures proper rendering with monospace font, and avoids interpretation of APL symbols as markdown.
