A programming language with a silly name
I saw recently the amazing movie La La Land and inspired by only the movie's name and my learning obsession I decided to learn how to make a programming language and give it a funny name 🙂.
Warning: This shouldn't be used in any production enviroment, it is very slow and poorly designed, it was made with educational purposes only.
The only requirement is to have Python 3.9+ (you can install it directly or with pyenv).
You can install with pip:
$ pip install lalalang
Or by source
$ git clone https://github.com/manoloesparta/lalalang && cd alalang
$ make setup env=python # Here goes the path of your python 3.9 executable
$ make install
Info: If the terminal returns command not found: 3lang
you should see where pip is installing your package and add that directory to PATH, sometimes using sudo
with pip solves it, or adding the --user
flag, if none of these options works can still use the interpreter with the command python -m lalalang
.
You can see the main options with this command
$ 3lang --help
Usage: 3lang [OPTIONS]
Options:
--mode TEXT REPL mode (lex|parse|eval)
--src TEXT Input file with 3lang code
--help Show this message and exit.
To enter the interpreter and run code on the fly, type
$ 3lang
Welcome to the city of stars!🌟
This is the La La Lang Programming Languag v1.2!
♪♪ >
To read a file and execute it, type
$ 3lang --src random_program.3la
You can enter other in the stages of lexing and parsing of the interpreter with the --mode
flag.
You can see the syntax of lalalang here.
See the examples directory to get a wider idea.
