# purpose of the project

This tests the publication of a Python wheel on the PyPI with
documentation originally maintained in a `README.org` file instead of
the officially supported `README.md`, `README.rst`, or plain text
`README.txt`.

## functionality by the script

As proof of concept, the functionality of the script is constrained to

- return a greeting
- betting good bye
- describe usage by optional flags `--help` and `-h`, as shown below:

``` bash
$ greet2org -h
usage: greet2org [-h] [-n str] [-g]

Greet, or bet good bye to someone. More importantly though, document the project
by a git managed README.org file instead of a README.md in GitHub flavored
Markdown.

options:
  -h, --help      show this help message and exit
  -n, --name str  The name to address (default: World)
  -g, --goodbye   Instead of a hello, bet good bye (default: False)
```

## documentation with Orgmode

Similar to [Markdown](https://en.wikipedia.org/wiki/Markdown) (`.md`)
and [reStructuredText](https://en.wikipedia.org/wiki/ReStructuredText)
(`.rst`), [Orgmode](https://orgmode.org/) (`.org`) is a [lightweight
markup language
(LML)](https://en.wikipedia.org/wiki/Lightweight_markup_language).
Contrasting to the many flavours of Markdown (and to somewhat lesser
degree reStructuredText) with subtle differences in syntax and support
of features, Orgmode *as a markup* is more strict. See for instance Karl
Voit's
[overview](https://gitlab.com/publicvoit/orgdown/-/blob/master/doc/Overview.org),
and [discussion](https://karl-voit.at/2025/08/17/Markdown-disaster/) in
comparison to Markdown.

Orgmode is well supported both as import and export format by
[pandoc](https://pandoc.org/). Depending on the editor used, Orgmode
files can be edited, included source code can be annotated ([literate
programming](https://en.wikipedia.org/wiki/Literate_programming)) and
executed ([example](https://youtu.be/fgizHHd7nOo?t=767)). Initially
created for [Emacs](https://www.gnu.org/software/emacs/) (where it
became an included major mode), Orgmode equally is available for
instance for [vim](https://github.com/jceb/vim-orgmode), or [Visual
Studio Code](https://github.com/vscode-org-mode/vscode-org-mode).
Equally see Karl Voit's compilation of tools supporting Orgmode markup
[here](https://gitlab.com/publicvoit/orgdown/-/blob/master/doc/Tool-Support.org?ref_type=heads).

Because PyPi currently does not provide support for Orgmode (see
[here](https://packaging.python.org/en/latest/guides/making-a-pypi-friendly-readme/),
last visit October 2025), GitHub workflow `build_wheel.yml` of this
project calls a Pandoc docker image to translate this file into a
`README.md` the PyPI can manage. The following compiles examples of
syntax known to be supported in the workflow, and indicates recognized
pitfalls.

To document a project, individual words can be marked as *italic*,
**bold**, `monospace` (enclosed in equal signs) and `monospace`
(enclosed by tildes). Snippets of code can be documented as *code
blocks* with optional syntax highlighting. By experimenting on
[test.pypi.org](https://test.pypi.org/), this is known to work for
instance with

- AWK:

  ``` awk
  #!/usr/bin/awk -f

  function ratio (long_lines, all_lines) {
    return sprintf("\n%s lines of %s (which is %.2f%% of the total) require an edit.",
      long_lines, all_lines, (long_lines/all_lines))
  }

  BEGIN {print "file, line number, and start of the line if a line length exceeds 79 characters:\n";
    counter = 0}

  {
    if (length($0) > 79) {
      printf("%s\t%5.i: %.40s\n", FILENAME, NR, $0);
      counter += 1;
      }
  }

  END {print(ratio(counter, NR)) }
  ```

- BASH

  ``` bash
  #!/usr/bin/env bash
  for "$file" in *.png:
  do
      optipng "$file"
  done
  ```

- Fortran

  ``` f90
  program test
     implicit none (external)
     integer :: i, double, square

     do i = -5, 5, 2
        double = 2 * i
        square = i ** 2
        write (*, "(3(i3, 1x))") i, double, square
     end do

  end program test
  ```

- Python

  ``` python
  #!/usr/bin/env python3
  for i in range(8):
      if i == 2:
          print("hello")
  ```

which may be used to execute Python code, or may be called by Python.

Note, already simple in-line mathematical equations (defined by an input
like `$E = mc^2$`) *are not* suitable for the `README.org`; they cause
the conversion to fail. Either consider a different location of
documentation, or embedd the equation as an illustration (*vide infra*).
Define external (literature) references by an link (example, link to
[PyPI](https://pypi.org/)), rather than a footnote.

## Orgmode tables

Orgmode tables are well supported, including their optional table
formulae. Depending on the renderer on GitHub or PyPI, captions however
may be lost, or not easy to discern from running text:

| x   | square of x | cube of x | square root of x |
|-----|-------------|-----------|------------------|
| 0   | 0           | 0         | 0.00             |
| 1   | 1           | 1         | 1.00             |
| 2   | 4           | 8         | 1.41             |
| 3   | 9           | 27        | 1.73             |
| 4   | 16          | 64        | 2.00             |
| 5   | 25          | 125       | 2.24             |

## Illustrations

PyPI supports illustrations only if defined with an absolute address to
the file in a repository outside PyPI. Permitted file formats include

- `.png`, as for instance the Wikipedia globe (source
  [here](https://en.wikipedia.org/wiki/File:Wikipedia-logo-v2.svg)):

  ![](https://upload.wikimedia.org/wikipedia/en/thumb/8/80/Wikipedia-logo-v2.svg/103px-Wikipedia-logo-v2.svg.png)

- static, or dynamic `.gif`, for instance to provide a brief (looped)
  demo. An example is file `Rotating earth (large).gif` as sourced on
  the Wikipedia project
  [here](https://commons.wikimedia.org/wiki/File:Rotating_earth_(large).gif):

  ![](https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif)

- PyPI equally accepts the reference to `.svg`, example (source
  [here](https://commons.wikimedia.org/wiki/File:Svg-example.svg)):

  ![](https://upload.wikimedia.org/wikipedia/commons/6/68/Svg-example.svg)

Shields and badges about a project (compare `README.org` for examples)
are a particular type of illustration. Frequently, it is safer to
collect them as `.svg` files (see documentation in workflow file
`collect_badges.yml`) and to use them by their address outside PyPI. In
case of GitHub, this follows the pattern of

``` bash
[[https://raw.githubusercontent.com/username/reponame/branch/directory/file.svg]]
```

This is relevant for instance to badges by
[shields.io](https://shields.io/) for which a Orgmode code block like

``` bash
#+begin_export html
<a href="https://github.com/psf/black"><img alt="Code style: black" src="https://img.shields.io/badge/code%20style-black-000000.svg"></a>
#+end_export
```

in the orgmode file *is not* reliably rendered by GitHub (October 2025),
while e.g.

``` bash
[[https://0dependencies.dev][https://0dependencies.dev/0dependencies.svg]]
```

is (both on GitHub and PyPI). Badges locally generated (for instance
with [genbadge](https://pypi.org/project/genbadge/), see the example
`Makefile`) preferably use the same folder.

## issues not addressed

This project is set up as a proof of principle where `build` /
`setuptools` is used as backend to compile a Python wheel. Among the
other backends *to build* a wheel the [Python Packaging User
Guide](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/)
describes, only [uv](https://pypi.org/project/uv/) was tested. Note the
names of the workflows to include the string `pip`, or `uv`,
respectively.

Most of the workflows of this project act / can be launched individually
of each other. With `CICD_publish_wheel.yml` one workflow combines
building a wheel (including the translation of the `.org` to `.md`) and
subsequent publication on test.pypi.org. This is to be lauched manually.
