To facilitate self-study, the resources here are classified by target audience. However, if you get stuck, don't hesitate to request help in the APL Orchard chat room or ask a question on Stack Exchange.
For non-programmers
Some of the best resources for somebody new to APL and programming in general are:
- APL Wiki's simple examples
- The Learn tab on TryAPL
- The book Mastering Dyalog APL by Bernard Legrand
- The Zark APL Tutor
- APL a Day: Introduction, Functions, Arrays, Values, Arrays have Shape
- A Practical Introduction to APL 1 & 2 (3 & 4 is for experts)
- Découvrez le langage APL : part 1, part 2, part 3 by Eric Schrafstetter (in French)
Follow one or a couple of these tutorials through and play around a bit. To learn APL the advice is similar to that for learning other languages: have a goal (something you want to accomplish) and try to do it. Along the way you are sure to come across the pitfalls and gotchas of the language, and with time you may come to understand what APL thinking means.
For non-APL programmers
This is a list of tutorials and other resources of interest to someone who knows about programming or is familiar with another programming language, but wants to learn more about APL.
- APL Wiki's advanced examples
- APL Wiki's Books
- APL Wiki's Papers
- APL Cultivation (chat lessons)
- TryAPL online interpreter with lessons
- Learn X in Y minutes
- Let's Learn A Programming Language
- Mastering Dyalog APL and its companion GitHub repository
- Zark tutorial
- Trying APL
- Artificial Neural Networks
- FizzBuzz
For novice APLers
If you already have a fair grasp of APL's primitive functions and operators, you can sharpen your skills by challenging yourself with these:
- 2016 Year Game: Find APL expressions involving exactly the digits 2 0 1 6 in that order to equal the numbers 0 to 100.
- 2017 Code Golf Challenge: Find the shortest possible APL expression that evaluates 1…52 without using any number or character literals.
- APL-eusis: A game for honing your ability to "think in APL".
For old APLers
In the last decade, several implementations have extended APL:
- New primitive functions:
⊢Same, Right;⊣Same, Left;⌷Materialise, Index;≡Depth, Match;≢Tally, Not Match;⍸Where, Interval Index;⊆Nest, Partition
- Lambdas (dfns): Intro; Details; Operators; The dfns workspace (collection of categorized utilities with extensive comments and notes)
- Tacit programming: Dyalog APL documentation: Intro; Details; short video; long video; APL Cultivation lesson
- Other features: Keywords; Object-oriented programming
For advanced APLers
Here is a list of "how-to"s on various subjects:
