Syntax

Lit is designed to look familiar to anyone, who touched any C-family language before. It resembles JavaScript a lot. Programs are stored in files with the .lit extensions as plain text and executed from top to bottom.

Comments

When you want lit to ignore a line, we prefix it with a double slash:

// This is a comment!
var a = 32 // This is a comment too

When the comment gets big and spans multiple lines it's better to use multiline comment syntax:

/*
 Look at me
 I'm multiline!
 */

Identifiers

Naming rules are generally simple: identifiers start with a lowercase letter or underscore, and may include digits, characters and underscores. Lit is case-sensitive.

hello
camelCase
PascalCase
SEND_HELP

Reserved words

Some identifiers in lit are reserved for special syntax constructions, here are all of them:

class, else, false, for, function, if, null, return, super,
this, true, var, while, continue, break, new, export, is,
static, operator, get, set, in, const, ref

Unary operators

So let's finally do something useful - let's use some unary operators! Lit has a total of three, not, negation and binary not:

print(!true)
print(-10)
print(~45)

Binary operators

If you find unary operators, you can be sure that binary operators are lurking somewhere nearby:

print(2 + 2)
print(10 + 8 - 9 * 10 / 3)
print(10 >> 2 | 9 << (4 & 0xff) ^ 0xaa)
