runno 0.1.0

Run untrusted code inside the Runno WebAssembly sandbox.

runno

Package for running code inside the Runno WebAssembly sandbox.

Quickstart

The run_code method allows you to run a snippet of code.

from runno import run_code

code = "print('Hello, World!')"
result = await run_code("python", code)

if result.result_type == "complete":
    print("OUTPUT:")
    print(result.tty)
else:
    print("ERROR")

Available runtimes are: python, quickjs, sqlite, clang, clangpp, ruby, and php-cgi.

Including Files

If you want to process files within your sandbox, you can include them in the file system by using the run_fs method.

from runno import run_code, WASIFS, StringFile
fs: WASIFS = {
    "/program.py": StringFile(
        path="/program.py",
        timestamps=WASITimestamps(
            access=datetime.now(),
            modification=datetime.now(),
            change=datetime.now(),
        ),
        mode="string",
        content="""
print(open('data.csv'))
""",
    ),
    "/data.csv": StringFile(
        path="/data.csv",
        timestamps=WASITimestamps(
            access=datetime.now(),
            modification=datetime.now(),
            change=datetime.now(),
        ),
        mode="string",
        content="""
a,b,c
1,2,3
""",
    )
}

await run_fs(runtime, "/program", fs)

Including Dependencies

You can use the same technique to include pure python packages as dependencies. The interface for this is not super nice right now, but it's on the way.
