Nuitka build system

Why? What the reason of this project?

OK, we already have nuitka, and it works. It allows to build any python file as executable or module.

But reality is...

• The most usual case in production is microservice monolith. It means the code base has many entry points. When you build single executable or single module, you are doing 95% of work twice or more. If you ready to wait forever until build complete, it's OK, but i'm not

• Some libraries with C-extensions and fallback python code work incorrect. It's much easier to exclude these libraries from build

Modules? Yes, but...

Yes, nuitka allow to split application code by modules. And since this moment you have to write large number build commands -- one command for each module. If you decided to split anything into separated module -- you have to rewrite all commands again, adding --nofollow-import-to=my_new_module. If you added any module, you have to rewrite all these commands again. And again...

Сonclusion

NuitkaBS helps you to create really large number of build commands via simple to read, undarstand and edit YAML config

Installing

pip install -U nuitkabs

Pre-requirements

You should know nuitka generate C-files and then compile it via gcc or clang. So, you have to install compiler (gcc or clang), python development headers. It will be good if you install ccache

Usage

NuitkaBS is really thin wrapper over Nuitka. The first thing you have to create nuitkabs.yaml file in root of your project. The most keys you see in YAML config you can find in nuitka documentation. Example:

modules:
  models:
  views:
  starlette_app:
  ubjson:
    include-module:
      - ubjson.encoder
  starlette:
    include-module:
      - starlette.applications
      - starlette.endpoints

# =========

executables:
  my_script:
  my_daemon:

# =========

generic:
  output-dir: ../build/
  lto:
  remove-output:
  warn-unusual-code:
  follow-imports:
  plugin-enable:
    - pylint-warnings
  nofollow-import-to:
    - sqlalchemy
    - pandas
    - ujson
    - orjson
    - greenlet

Just compare keys and nuitka help page. They are the same.

Compile external library

Just look the example. Find ubjson and starlette modules. Yes, there are external libraries

Some tricks

List or single item

There is no difference between single item and item list:

generic:
  output-dir: 
    - ../build/

If you have nothing to say, don't say

If you have to enumerate your modules, but you have nothing to put as value -- just let value empty
