Liner

A mistake, probably

What is Liner?

Liner is a functional language, designed to solve no problems currently facing us.

In Liner each statement is limited to a single line of code. With the Lineeeee number based system. This means that Liner does have a slew of.... features.....

This includes, but is not limited to!

Long files for simple tasks! No floating point numbers! No pesky Strings! Really not a lot of anything! Recursion.....? Kinda? Mistakes! And more!

The included Liner Interpreter is made using Python, a programming language worth learning instead of this one.

How does one program in Liner?

Programming in Liner is simple! Just look in the repo for the "Hello World" example!

Namespace

Namespaces are critical to Liner code, without them, nothing can work. For Liner the statement's Namespace is the unique set of characters at the start of the line. These are allowed to be any letter, case-sensitive, as long as it's not a keyword.

Liner namespaces are declared with no leading whitespace, and are immediately followed with a semi-colon. Whitespace is considered a unique character, so although it can be placed inside the namespace, this is frowned on because I'm making the language, and I say so.

C;Examples
Name;
 IllegalName;
Bad Name;
CantUseThisOne;
GoodName;
A;

C is both considered to be a keyword, and not. Interpreter will skip lines beginning with C, this includes any word beginning with C. This is given to the developer for the sake of comments. However this practice can be highly debated, and leads perfectly into the next segment.

Properties

All namespaces have a numeric property, and is where Liner takes it's name from! In any function, by putting only the namespace in a location, you can use the number line the namespace was declared on. Hence to add the numbers 2 and 3 together, you could write the following.

C; assume this is line 1 of the file
A;
B;
D; A add B
E; prin D()
E()

As number line can't go negative, to get a negative number, you'd have to subtract two numbers. The following would print a negative one.

C; assume this is line 1 of the file
A;
B;
D; A sub B
E; prin D()
E()

Functions and Variables

The difference in Liner is that there isn't one, kinda.

As the only "real" variable type is the numeric property of the namespace, we have to get creative. This means a proper Liner programmer should be able to understand how to number good.

Anything after the namespace on the same line is considered to be a function. If there is nothing there, that namespace can be used to end the program. A function is anything on the same line, and should only include one keyword. If a function calls another function, that is assumed to be the return value, which is important for the prin keyword.

Keywords

  • prin Prints the results of all the following function, and the numeric value of any namespace.
  • let converts an integer into its Unicode character.
  • if returns the highest number of two different namespaces/function
  • set override the numeric value of a namespace, and replaces the original in duplicate cases.
  • run Run the function at the given numeric property, if no function is there, crashes.
  • add add two numeric properties
  • sub subtracts two numeric properties
  • split allows for two function calls on one line.
  • in lets the user input a number from the console
