WARNING: This repo is in active development.
boba-script is a general purpose interpreted programming language intended to be used with another one of my projects boba-engine. While it does not contain any code that references the engine, its internals are built in a way that allows it to be transformed into a domain specific language for that purpose. This means that it does not have to be a DSL for boba-engine specifically, but it can be used as a general purpose language or transformed into a DSL for another purpose.
The best way to try out the current version of boba-script is to use the interpreter.
To run the interpreter, first clone the repo.
git clone https://github.com/rhedgeco/boba-script.git
Then navigate into the interpreter folder.
cd boba-script/interpreter
Then run the code!
cargo run --release
The current feature set is incredibly limited and will be developed over time.
There are a few different value types in bobs-script
-
None Type - e.g.
none
- boba-script does not have nulls, and instead an explicit none type can be used to represent nothing.
-
Int Type
- int types are any whole number. e.g.
5
,42
- integer types have no bound in the size of number they can hold
- int types are any whole number. e.g.
-
Float Type
- float types are any decimal number
- these can be constructed by their full representation like
12.5
a trailing decimal notation like14.
or a trailing 'f' notation like this20f
- internally the float uses 64 bit precision
-
Bool Type
- the bool type can be one of two values.
true
orfalse
- the bool type can be one of two values.
-
String Type
- string types are a buffer of characters
- they can be constructed with single quotes
'hello world'
or double quotes"hello world"
-
Tuple Type
- tuples are a grouped collection of items
- they can be created as a comma seperated list surrounded by braces like this
(5, 'hello', 8.9)
To create a variable use the 'let' syntax and assign a value
let my_var = 5
Variables can also be assigned to after they are initialized like this
my_var = 20
Assignments can destructure their items on the right hand side
let (a, b, c) = (10, 42, 750)
This also means that swapping variable vales does not need a temp variable
let a = 10
let b = 42
(a, b) = (b, a) # this line swaps the values
While loops may be constructed like this
while my_var > 0:
# do something here
Functions may be constructed like this
fn my_func(value):
# do something here
Functions can be called like this
my_func('hello world')
