The tyler Language

The world's most useless programming language™️!

Language Definition

The tyler language (which uses extensions .tyler or .ty) is something I made because I thought it would be "fun". There are no practical applications for this language, and trying to use this language for a practical application is against the rules.

Data Types

tyler has 3 data types, because tbh you don't need anymore.

  • Values

    This is any single value, like text or a number

  • Lists

    A list can be made up of any of the three data types

  • Execs

    A reusable bit a code, that, once defined, can be executed like any of the five core commands

Commands

tyler has five core commands

t

Tells something, in other words, this is the print statement, and it works for any of the three data types
t $value|$list|$exec

  • value

    Prints the value

  • list

    Prints each item in the list (essentially just calls t on each)

  • exec

    Prints out the code stored for this exec

y

Yells something, essentially the same as t, but it'll be in all-caps
y $value|$list|$exec

l

Creates a list with the given name and items (space separated)
l $name $item1 $item2 ... $itemN
Items can any of the three data types

e

Create an exec
e $name $code
$code can be any of the five commands, or another exec:

  • e greeting t hello
greeting
    would print "hello"
  • e greeting t hello
e hello greeting
hello
    would print "hello"
  • e initList l stuff test 1 foo
initList
    would initialize the list "stuff" with items test, 1, and foo

r

This command has two different functions, depending on syntax

  1. Repeat a line When a line with just r is placed below another line of the code, r will repeat that line's execution:

    t hello
r

    would print out:
    hello
    hello

  2. "Repeat" the contents of a list
    This will iterate over all the items in a list and evaluate them based upon their type

    • value
      Prints the value (effectively t $value)
    • list
      Repeats the contents of the list (effectively r $list)
    • exec
      Executes the exec
