APLcart

APLcart is the largest ever collection of short APL phrases, comprising idiomatic expressions from Dyalog APL, FinnAPL, and APL2, and lots of other sources, including the community at large.

There is plenty of documentation suites about what different parts of APL do. For example, in many IDEs, one can press the F1 key while the caret is pointing at a primitive functions or Quad-names to open the appropriate documentation. However, APLcart comes to answer "How do I…" questions.

It is intended for both beginners and professionals, but knowledge of basic APL syntax is a prerequisite.

Created and maintained by Adám Brudzewsky, it invites the general APL community to contribute through GitHub pull requests and templated issues.
