benji4000
The "other" lost personal computer of the 80s. It was similar to the better known C64 but programmed in a higher-level (and much more imaginary) language.
To build the code
go build
To run a bscript file
For example:
./benji4000 -source=src/adventure.b
bscript
The programming language of benji. Execution starts by calling the function named "main".
Features:
- single line comments:
# this is a comment - variable declarations:
a := 1;Global variables are declared outside of any function. Variable values can be a number, a string, an array or a map. - constants:
const PI=3.14159; - strings:
a := "hello"; - control flow:
if(a = 1) { doSomething(); } else { doSomethingElse(); } - loop:
while(a < 10) { a := a + 1; } - arrays:
a := [1, 2, 3]; - maps:
a := { "a": 1, "b": 2 };Map keys are always strings, values can be anything (including other maps.) - function definitions:
def hello(x) { print(x); } - function calls:
f(g(123)); - builtin functions:
- length: the length of a string, array or map
- keys: returns a map's keys as an array (always strings)
- substr: substring, for example:
substr("Hello World", 1, 2)prints "el" - print: print strings + variables
- input: ask for user input
- debug: print closures and stack trace
- assert: assertion testing
- first class functions:
def f(x) { return 2; } x := f;- functions as parameters
- anonymous functions:
def f(x) { return (n) => { return x + n; }; } - and in short form:
def f(x) { return n => x + n; }
Coming soon:
- boolean operators (and, or, not)
bscript syntax highlighting
The vscode directory contains a plugin for syntax highlighting for .b files.
