Common markup for Markdown and reStructuredText

Markdown and reStructuredText

GitHub supports several lightweight markup languages for documentation; the most popular ones (generally, not just at GitHub) are Markdown and reStructuredText. Markdown is sometimes considered easier to use, and is often preferred when the purpose is simply to generate HTML. On the other hand, reStructuredText is more extensible and powerful, with native support (not just embedded HTML) for tables, as well as things like automatic generation of tables of contents.

How to use Markdown as a filter in a Jinja2 template, and then extract the Markdown Meta property directly from the template. Assuming you want to use the Meta-data value before rendering the converted Markdown content (e.g. in the html head), the trick is to render the markdown first, save it to a variable (html_content in this example) using a…
from pprint import pprint
import jinja2
import markdown
HTML_TEMPLATE = """{% macro get_html() %}
{{ content | markdown }}
{% endmacro %}
{% set html_content = get_html() %}
Title from Markdown meta-data: {{ get_title() }}

Last active August 29, 2015 14:27 — forked from marcusphi/ansible_conditionals_examples.yaml
Ansible 1.3 Conditional Execution -- Very complete example with comments -- I find the conditional expressions to be ridiculously hard to get right in Ansible. I don't have a good model of what's going on under the surface so I often get it wrong. What makes it even harder is that there has been at least three different variants over the course …

# This has been tested with ansible 1.3 with these commands:
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=false"
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=true"
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts"
