Bulb
Bulb is a simple Lisp dialect very similar to Scheme on which I work in my free time. The ultimate goal of the project is to create a lightweight interpreter, easy to integrate on other projects. Here are some examples of the syntax:
Basics
; this is a comment
(def integer 1)
(def floating 3.1415926535)
(def flag #f) ; #f stands for false, #t for true
(def str "potatoes") ; this a string
; functions can be defined like this
(def (abs x) (if (> x 0) x (* x -1)))
; or like this
(def abs (lambda (x) (if (> x 0) x (* x -1))))
; more complex example of code
(def (print-list l)
(if (and (list? l) (not (null? l)))
(begin
(print (car l) " ")
(print-list (cdr l)))))
(print-list (list 1 2 3 4 5)) ;=> 1 2 3 4 5
(print "\n")How to install
First of all, you need the source code. Download the tarball or clone the repository:
git clone https://github.com/bnzis/bulb
You need make and a C compiler. If you're a Linux or BSD user, you probably already have both; if not, consult the manual of your distribution to install them. If you use Windows instead, I recommend installing MinGW. Compile and install:
cd /path/of/bulb
make all # please check config.mk before building
sudo make install # works only on Linux and BSD.
How to use it
bulb # open the repl
bulb /path/to/file # execute the code in the file
