Smalc
Smalc is a joke calculator (created to be better than Desmos) implemented as a project to learn Elixir. Created by User:Joe
Spec
Literals
There are no number literals in the calculator, only identifiers. If an identifier can't be found in the context, it's then treated as a base 16 number. The language was implemented this way so you could redefine the values of numbers.
Operators
What the math operators correspond to in Smalc: All operators are right-associative as well.
| Operator | Type | Symbol | Precedence |
|---|---|---|---|
+
|
prefix | min
|
60 |
-

infix | max
|
70 |
*
|
postfix | +
|

Preprocessor
Before the program is interpreted, every [ in the text is replaced with ((( and every ] is replaced with )).
Brackets
Expressions can be bracketed with mismatching (, ), [, ], {, }. But because of the way they're implemented in the parser, you can't nest bracketed expressions lol.
Variables
Variables are defined as such:
: expr ident : expr
Identifiers are any sequence of alphanumeric characters.
When accessing a variables, you reverse the name. A variable defined as PI would be accessed as IP.
Examples
(((1400 * 1000000) / 1) - 16) + 4000000
is equivalent to
min {578 F4240 + - 1) max 10 3D0900
in Smalc.
