Miniscript is an imperative, Javascript-esque language with dynamic information flow control.
The language is interpreted and complete with conditionals, loops, and user function definitions, and support primitive types of strings, numbers and arrays. You can look at in the samples folder for more more information on how to write miniscript.
The interesting part about miniscript is the security labels that are built into the language that enable control of information flow. A label l for a value is defined as {s_1, s_2, ..., s_n}, where the s values are unique strings. This makes a label a set of unique strings. In order to "have clearance" for the access to a value the label l_1 of access needs to be a subset of l_2 where l_2 is the label of the variable.
Create a python virtual envrionment using python -m venv .venv or virtualenv .venv and then activate it using source .venv/bin/activate. Then run pip install -r requirements.txt to set up the development environment.
You should now be able to run make test successfully.
You can use runner.py to run the sample scripts in samples/. It can also be used interactively.
> python runner.py samples/fibo.ms> python runner.py

print(x);The main gola of this project is having some challenges to overcome different levels of information flow control.
To run them, follow the steps in installation and then go to the challenges directory.
Each of its subdirectories contains a challenge which you can run if the virtualenv is active.
A solution is provided along with each challenge.
