CLI to embed (testable) snippets from your codebase into your README

	Status	Stable	Unstable
Master
Develop

❔ What

What it does: Snipinator lets you take a EXAMPLE.md template and include snippets from your (working and tested) codebase.

Turn this (./examples/SIMPLE.md.jinja2):

# A README

Here is a code snippet:

<!--{{ pysnippet(path='examples/code.py', symbol='MyClass', backtickify='py', decomentify='nl') }}-->

Note that `code.py` has a test:
{{path('./examples/code_test.py', link='md')}}.

Into this (./examples/SIMPLE.generated.md):

# A README

Here is a code snippet:

<!---->
```py
class MyClass:
  """This is a global class"""

  def __init__(self, name):
    self.name = name

  def MyClassMethod(self):
    """This is a method of MyClass"""
    print(self.name)
```
<!---->

Note that `code.py` has a test:
[./examples/code_test.py](./examples/code_test.py).

🎇 Features

📦✅🪄 Supports anything Jinja2 supports.
🥇🐍📜 First-class support for python source code.
- Can include python function signatures, docstrings, entire function source code, classes.
✂🌐🗂️ Snip from any source code language.

🥇🔖📜 First-class support for Markdown templates (with backtickify, decomentify).
📦🐚🖨️ Can include shell output.
- Supports ANSI colors ❤️ 💚 💙 with SVG output 📷.
⚙️🔗🗃️ More robust references/links to local files using path().
🐳🌊🖥️ Docker Image (See README: Docker Image).

🚸 Gotchas and Limitations

Security: This tool is NOT designed to be used with untrusted input. It is designed to be used with your own codebase. Even when using your own input, be careful that your own code won't be doing anything that might inadvertently include untrusted input.
Be careful to escape {{ and }}, or {% and %} or anything jinja2 is sensitive to, in the templates. You'll have to escape it properly for jinja2, which involves using {% raw %} and {% endraw %} tags.
Recursion: Snipinator doesn't directly support recursive inclusion of generated content. You can generate the contents of one file first, and include that generated content into another template. This would mean that you have to worry about order of generation.
Embedded Backticks: If there are backticks in the included snippet, it might ruin the backticks you have in your markdown. This is why backtickify parameter exists in the API, so that Snipinator provides the backticks, and it will detect if there are backticks in the snippet and use a different number of backticks on the entire snippet. So if the snippet contains ```My Snippet```, Snipinator will use ````language ```My Snippet``` ```` and this is a method that Markdown uses to allow embedded backticks inside a code block.
Formatting: The {{ }} used to surround the snippet calls will unfortunately be formatted by a Markdown formatter and make the call invalid. Workarounds:
- Decommentify: Put the snippet call inside a HTML comment, then use decommentify parameter. See ./examples/LONG-EXAMPLE.md.jinja2 for examples.
- prettier formatter is pretty good at leaving the Jinja2 calls alone, especially if you don't have any spaces. This especially helps for markdown "reference-style links" that have Jinja2 calls in them generating part of the URL, mdformat will URL encode the Jinja2 calls, and/or split them on spaces, which is not what we want. prettier will leave them alone.
- For code blocks: If you embed the snippet call in a code block, it will not be formatted. However, because of Embedded Backticks gotcha, (see above), this is not recommended, unless you know for sure that there are no embedded backticks.
- If your formatter supports a comment that disabled formatting, you can surround the snippet call with that comment.
Editing the wrong file: When you have a template and a generated file, it is easy to edit the wrong file. To combat this:
- Snipinator provides a warning at the top of the generated file to remind you that it is auto-generated.
- Snipinator will optionally chmod the file for you to make it read-only.
Newlines: This program assumes LF newlines. I don't know if it will work for anything else.
Combining backtickify and indent: Doesn't make much sense, but if you do it, it will run backtickify first, then indent everything including the backticks.

Development environment: Linux-like

For running pre.sh (Linux-like environment).

From ./.github/dependencies.yml, which is used for the GH Action to do a fresh install of everything:

bash: scripts.
findutils: scripts.
grep: tests.
xxd: tests.
git: scripts, tests.
xxhash: scripts (changeguard).
rsync: out-of-directory test.
expect: for `unbuffer`, useful to grab and compare ansi color symbols.
jq: dependency for [yq](https://github.com/kislyuk/yq), which is used to generate
  the README; the README generator needs to use `tomlq` (which is a part of `yq`)
  to query `pyproject.toml`.
unzip: scripts (pyenv).
curl: scripts (pyenv).
git-core: scripts (pyenv).
gcc: scripts (pyenv).
make: scripts (pyenv).
zlib1g-dev: scripts (pyenv).
libbz2-dev: scripts (pyenv).
libreadline-dev: scripts (pyenv).
libsqlite3-dev: scripts (pyenv).
libssl-dev: scripts (pyenv).
libffi-dev: bdist_wheel (otherwise `pip install .` fails). If installing pyenv, this
  must be installed _first_.

On Ubuntu: sudo apt-get update and then sudo apt-get install -y bash findutils grep xxd git xxhash rsync expect jq unzip curl git-core gcc make zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev libssl-dev libffi-dev.

Requires pyenv, or an exact matching version of python as in ./.python-version (which is currently 3.8.0).
act (to run the GH Action locally):
- Requires nodejs.
- Requires Go.
- docker.
Generate animation:
- docker
docker (for building the docker image).

Commit Process

(Optionally) Fork the develop branch.
Stage your files: git add path/to/file.py.
bash ./scripts/pre.sh, this will format, lint, and test the code.
git status check if anything changed (generated ./README.md for example), if so, git add the changes, and go back to the previous step.
git commit -m "...".
Make a PR to develop (or push to develop if you have the rights).

🔄🚀 Release Process

These instructions are for maintainers of the project.

In the develop branch, run bash ./scripts/pre.sh to ensure everything is in order.
In the develop branch, bump the version in ./pyproject.toml, following semantic versioning principles. Also modify the last_release and last_stable_release in the [tool.snipinator-project-metadata] table as appropriate. Run bash ./scripts/pre.sh to ensure everything is in order.
In the develop branch, commit these changes with a message like "Prepare release X.Y.Z". (See the contributions section above).
Merge the develop branch into the master branch: git checkout master && git merge develop --no-ff.
master branch: Tag the release: Create a git tag for the release with git tag -a vX.Y.Z -m "Version X.Y.Z".
Publish to PyPI: Publish the release to PyPI with bash ./scripts/deploy-to-pypi.sh.
Push to GitHub: Push the commit and tags to GitHub with git push && git push --tags.
The --no-ff option adds a commit to the master branch for the merge, so refork the develop branch from the master branch: git checkout develop && git merge master.
Push the develop branch to GitHub: git push origin develop.
