navxio/dopy: Python without strict indentation

An experimental Python preprocessor that enables do..end syntax in place of strict indentation

• Converts to ruby/lua style do..end blocks to indented blocks
• Continuing with python semantics
• String literals and comments are preserved
• Processes .dopy files into pep8 compliant .py files (maintaining dir structure)
• supports type tips
• Transpiles import simultaneously

from dopy.core import Dopy
dopy = Dopy()

source = '''
def hello_world() do
  print("Hello")
end
hello_world()
'''

processed = dopy.preprocess(source)
exec(processed, namespace={})

dopy my_module.dopy

Use the currently active python interpreter, can be overridden by PYTHON_PATH env before

-h,--help: Print help text

-k,--keep: Keep transpiled python files in place (overwrite)

-s,--stdout: Print the transpiled python code to console and exit

-c,--check: Check dopy syntax without transpiling

• Make sure the do keyword is on the same line as the rest of the block declaration,
• end should be on its own line
• all import above module
• must make and __init__.py dirs file to identify the transpiled python modules
• Keep imports relative to the directory structure, just like regular Python

This project is very inspiring mathialo/bython

I built it to learn more about python/interpreter language syntax in general, but am not interested in continuing with it.
