About¶
Minimal I/O Interpreter¶
This is a minimal I/O Interpreter. This is a rewrite of:
Warning
mio is a new programming language in early Development.
DO NOT USE IN PRODUCTION!
USE AT YOUR OWN RISK!
Prerequisites¶
It is recommended that you do all development using a Python Virtual Environment using virtualenv and/or using the nice virtualenvwrapper.
$ mkvirtualenv mio
You will need the RPython toolchain to build the interpreter. The easiest way to do this is to My Fork of PyPy which includes a convenient setup-rpython.py to make working with the RPython toolchain a bit easier.
$ hg clone https://bitbucket.org/prologic/pypy
$ cd pypy
$ python setup-pypy develop
$ python setup-rpython.py develop
Installation¶
Grab the source from https://bitbucket.org/miolang/mio and either run python setup.py develop or pip install -r requirements.txt
$ hg clone https://bitbucket.org/miolang/mio
$ cd mio
$ pip install -r requirements.txt
Building¶
To build the interpreter simply run mio/main.py against the RPython Compiler. There is a Makefile that has a default target for building and translating the interpreter.
$ make
As of 690c894 you can now build mio using Docker and fig.
$ fig build
Usage¶
You can either run the interpreter using Python itself or by running the compiled interpreter mio in ./bin/mio.
$ ./bin/mio examples/hello.mio
Untranslated running on top of Python (CPython):
$ miopy examples/hello.mio
As of 690c894 you can now run mio using Docker and fig.
$ fig run mio hello.mio
Grammar¶
The grammar of mio is currently as follows:
program = expressions
expressions = { expression }
expression = message | terminator
message = symbol | arguments | symbol arguments
arguments = T_LPAREN arguments_list T_RPAREN |
T_LBRACE arguments_list T_RBRACE |
T_LBRACKET arguments_list T_RBRACKET
arguments_list = expressions | expressions T_COMMA arguments_list
symbol = T_IDENTIFIER | T_OPERATOR | T_NUMBER | T_STRING
terminator = T_TERMINATOR
