Flask-FlatPages-Knitr

Flask-FlatPages-Knitr preprocesses a Flask FlatPage using knitr such that code chunks are evaluated before the next step in the rendering process occurs.

Quickstart

First, install the knitr R package:

Rscript -e "install.packages('knitr')"

Right now, Flask-FlatPages-Knitr requires at least version 0.6 of Flat-FlatPages, which has not been released yet. Hence, you'll have to install it from Github:

pip install git+git://github.com/SimonSapin/Flask-FlatPages/

Second, install Flask-FlatPages-Knitr from the Python Package Index:

pip install Flask-FlatPages-Knitr

Finally, you can simply add Flask-FlatPages-Knitr to your app:

from flask import Flask
from flask_flatpages import FlatPages
from flask_flatpages_knitr import FlatPagesKnitr

app = Flask(__name__)
app.config.from_object(__name__)

pages = FlatPages(app)
FlatPagesKnitr(app)

By default, FLATPAGES_HTML_RENDERER will be reused, which defaults to a Markdown implementation for Python. For more advanced Markdown rendering, Flask-FlatPages-Pandoc is recommended:

from flask_flatpages_pandoc import FlatPagesPandoc

FLATPAGES_EXTENSION = ".Rmd"

pages = FlatPages(app)
FlatPagesPandoc("markdown", app, ["--mathjax"], pre_render=True)
FlatPagesKnitr(app)
