LINR
Summary
LINR is an interpreted language invented by Sam Lord in March 2017. The name alludes to the unconventional order in which the written code may be run.
Operations
LINR has five operations.
| Operation | Arguments | Summary |
|---|---|---|
| ADD | [val/var] [val/var] [var] |
Adds the left value or variable to the right value or variable and stores the result in the final variable |
| SUB | [val/var] [val/var] [var] |
Subtracts the right value or variable from the left value or variable and stores the result in the final variable |
| MUL | [val/var] [val/var] [var] |
Multiplies the left value or variable and the right value or variable and stores the result in the final variable |
| DIV | [val/var] [val/var] [var] |
Divides the left value or variable by the right value or variable and stores the result in the final variable |
| NUL | [Anything] |
NUL acts as a comment. Anything can be included in its arguments and it's ignored at runtime. It is, however, included in the instruction count. |
Execution order
The order of execution of LINR programs is dependant on the modulus 8 of the number of operations. Starting from line 0 the program is stepped through skipping [linecount]%8 lines. Then, the starting point of the program is increased to 1 and so on. The program completes when all operations have been run. No operation is completed twice.
It is worth noting that only the second section of the code, containing the operations themselves, are taken into account when determining the line skip value.
Example code
The code of LINR is split into two sections separated by an @ symbol. The first half is variable declaration and the second are the operations. Operations may only be performed on float-like values and variables.
; a; b; c; d; e; @ ADD 1 0 a; ADD 2 0 b; ADD 3 0 c; ADD a b e; ADD c e e; MUL c b d; DIV e 2.43 e; SUB e 6.78 e; NUL Literally anything can go here, probably;
The above code will set ; to be the operation separator, a-e as variables and then all instructions after the @ sign are executed in order.
If the final NUL Literally anything can go here, probably; instruction is removed, the program will hang due to the [linecount]%8 being equal to 0 therefore only allowing the first operation to execute.
The above code completes with the variables containing the following a:1, b:2, c:3, d:6, e:-4.310864
Each instruction needn't be on a new line, however it is presented here as such to make it more readable.
Interpreters
As of the time of writing, only one interpreter exists for LINR and it's called LINR. See Resources.
