HLAAPL

HLAAPL, which stands for Human Language as a Programming Language, is an esolang that tries to simulate natural language syntax. Any natural language can be used; this article will primarily be using Esperanto. To add a bit of esotericness, you should try to write your programs in a language that you don't know.

Input and Output

To make the program output something, you conjugate the word for "to write" in the singular imperative and put the thing you want to output as the object. In quotes if a string, not if a variable or number.

Skribu "Saluton, la mondo!".

This program outputs a string.

Skribu dudek du.

This program outputs the number 22. You can also ouput 2 things at the same time.

Skribu ok kaj "skribu".

To collect input, the word for "to ask for" is conjugated in the singular imperative. and then the word for "number" or "phrase" is put as the object. To assign it to a variable, you write "The answer is (variable name)." where the variable is a definite noun phrase.

Demandu nombron.
La respondo estas la nombro.
Skribu la nombron.

This outputs the number that's inputed.

Variables

Variables are definite noun phrases. To assign a value to a variable, you use the word for "to be" and the value that you want to set the variable to. It can be a number or a string. Mathematical operations are what they are in the language.

La unua nombro estas du.
La dua nombro estas okcent kvindek kvin.
Skribu la unuan nombron kaj la dunan nombron.

Loops

To make a loop that repeats until a certain condition is met, you use "to repeat" in the imperative, followed by "until" with the object of the preposition being the condition. Then, you put the lines to repeat indented. Conditions can be "is" or "is less/greater than" and can be negated normally.

La nombro estas ok.
Ripetu ĝis la nombro estas unu:
    Skribu la nombron.
    La nombro estas la nombro minus unu.

This program would print the numbers from 8-2.

If Statements

To make an if statement, you use the word "if". For "else", "if no" is used.

La nombro estas du.
Se la nombro estas du,
     Skribu "yay".
Se ne,
     Skribu "sad".

This programs outputs "yay" is the number is two, and "sad" is the number isn't two.

Goto

To create a goto label, you write "This instruction is (adjective)." The adjective is the name of the label. To jump to the label, you write, "Go to the (adjective) instruction."

Tiu ĉi instrukciono estas bona.
Iru al la bona instrukciono.

This causes an infinite loop.

Functions

You can make custom functions. To do that, you pick a verb (in its dictionary form) and put "is" after it. You can put parameters such as "phrase" (as a string), "number" (as a number), "verb" (as a verb) and "type" (as an adjective). Each noun parameter must be indefinite, and have an ordinal number. These act as variables in the code of the function.

Grandi unuan nombron je dua nombro estas:
     La unua nombro estas la unua nombro plus la dua nombro.

This function adds two numbers together. It could be used as such:

La granda nombro estas ok.
Grandu la grandan nombron je okdek.
Skribu la grandan nombron.

This would print 88.
