Flarf allows you to filter flask request to your specification within your application, providing convenient access in your appplication and templates.

Example for example purposes(see example app in examples directory):

example.py: ------

from flask import Flask from flask.ext.flarf import Flarf, FlarFilter

def format_from_request(request):

return """

<h1>HEADER: {}</h1>n header: {}n <h1>METHOD: {}</h1>n ARGS: {}n """.format(request.headers.upper(), request.headers, request.method.lower(), request.args)

flarf_filter = FlarfFilter(filter_tag='flarf_filter',

filter_params=[format_from_request, 'my_val'], filter_on=['includeme'])

app = Flask(__name__) Flarf(app, filters=[flarf_filter])

@app.route("/includeme") def index(): return render_template("index.html")

index.html: ----------

MY_VAL: {{ flarf_filter.my_val | safe }} MY_REQUEST: {{ flarf_filter.format_from_request | safe }}

Run the app and visit: http://127.0.0.1:5000/includeme?my_val="helloworld"

Suggestions, input, & improvements welcomed.
