Ling is a simple, interpreted programming language created for fun and learning. It provides basic programming principles and is designed to be easy to use. Ling is a WIP and everything is subject to change.
-
Variable Declaration: Create and manipulate variables easily.
-
Print Statements: Output text and variable contents to the console.
-
Basic Arithmetic: Perform addition, multiplication and division operations on integers.
-
File-based Execution: Run Ling scripts from text files.
-
Basic If Statements: Compare values easily.
To run a Ling script, use the following command from a folder containing Ling.exe:
Ling script.ling
To print a line of text:
PrintLine("yello warld")
To print the value of a variable:
PrintLine(VariableName)
You can also use Print to not make a new line, call them the same way.
These are the only existing functions.
Functions can't have arithmetic as a parameter just yet.
To declare and initialize a variable:
Variable MyVariable = 123
Variables can store strings or numbers, but are orientated towards numbers
Determine whether or not to run code by following this basic process.
If 1 == 1 Run
{
code here
}
Not following this syntax can cause errors.
Basic addition is supported for integers:
Variable a = 5 + 5
Variable b = a / 2
Variable result = a * b
Variable sum = result + 10
PrintLine(sum)
Result: 60
There is no order of operations.
Lexer defines change the way the lexer behaves when interpreting your script.
Lexer defines can be used with:
DEFINE TREAT_WARNINGS_AS_FATAL 1
or
DEFINE TREAT_WARNINGS_AS_FATAL false
TREAT_WARNINGS_AS_FATAL
Changes the way warnings are treated, if the lexer discovers a warning and this is true or 1, your script will stop being interpreted and the lexer will stop.
DISABLE_CASE_SENSITIVE_FUNCTIONS
Allows you to call functions regardless of capitals, example:
pRintLiNe("hello world")
You can find an example script in script.ling
