DG – A(n) (unusual) programming language
General structure
- There are no infix-operators (i.e. 1 + 1)
- Each operator takes 2 parameters
- When there are more than 2 parameters required, they will be listed by “,”
- Code is interpreted line by line
- There must not be blank lines
- Any character that isn’t an operator starts a comment (“;” is the only one that I can guarantee will stay a comment going forward)
Syntax
A line followes the general structure [operator] [first parameter] [second parameter]
Operators
| Operator | Description | Syntax |
|---|---|---|
| v | set variable | s x 15 [also s a x (sets a to 15)] |
| v | make an array | s b [] |
| v {o} | sets variable to output of equation | s c o / 1 2 [sets var c to 1 / 2; if s c o * 3 4 c = 12] |
| + | adds to numbers (only used to set variables) | v e o + 1 2 |
| – | subtracts to numbers (only used to set variables) | v e o - 1 2 |
| * | multiplies to numbers (only used to set variables) | v e o * 1 2 |
| / | divides to numbers (only used to set variables) | v e o / 1 2 |
| % | modulo of to numbers (in this case used to set variables) | v e o % 8 3 |
| g | gets element of array and writes to variable | v e o g b 0 |
| p | prints variable | p "x: {}, a: {}" x,a [see rusts println!] |
| a | append to array | a b 15 [b = [15]] |
| s | sets element in array | s b 0,12 [b = [12]] |
| g | get element in b | g b 0 [prints 12] |
| ; | comment | ; I'm a comment |
| > | executes if condition is true | > x 1 v e o / 1 x [if x > 1, e will be set to 1 / x] |
| < | executes if condition is true | < x 1 v e o / 1 x [if x < 1, e will be set to 1 / x] |
| = | executes if condition is true | = x 1 v e o / 1 x [if x == 1, e will be set to 1 / x] |
| ! | executes if condition is true | ! x 1 v e o / 1 x [if x != 1, e will be set to 1 / x] |
| l | basic for loop | l 1,10,2 i&v z o / 1 i&p "i:{} z:{} i,z" [for i from 1 to 9 in steps of 2 (1, 3, 5, etc.) set z = 1/i and print i,z. BEFORE AND AFTER THE “&” MUST NOT BE A SPACE] |
