RoboBrowser is a simple, Pythonic library for browsing the web without a standalone web browser. RoboBrowser
can fetch a page, click on links and buttons, and fill out and submit forms. If you need to interact with web services
that don't have APIs, RoboBrowser can help.

.. code-block:: python

import re
from robobrowser import RoboBrowser

# Browse to Rap Genius
browser = RoboBrowser(history=True)
browser.open('http://rapgenius.com/')

# Search for Queen
form = browser.get_form(action='/search')
form # <RoboForm q=>
form['q'].value = 'queen'
browser.submit_form(form)

# Look up the first song
songs = browser.select('.song_name')
browser.follow_link(songs[0])
lyrics = browser.select('.lyrics')
lyrics[0].text # \n[Intro]\nIs this the real life...

# Back to results page
browser.back()

# Look up my favorite song
browser.follow_link('death on two legs')

# Can also search HTML using regex patterns
lyrics = browser.find(class_=re.compile(r'\blyrics\b'))
lyrics.text # \n[Verse 1]\nYou suck my blood like a leech...

RoboBrowser combines the best of two excellent Python libraries:
`Requests <http://docs.python-requests.org/en/latest/>`_ and
`BeautifulSoup <http://www.crummy.com/software/BeautifulSoup/>`_.
RoboBrowser represents browser sessions using Requests and HTML responses
using BeautifulSoup, transparently exposing methods of both libraries:

.. code-block:: python

import re
from robobrowser import RoboBrowser

browser = RoboBrowser(user_agent='a python robot')
browser.open('https://github.com/')

# Inspect the browser session
browser.session.cookies['_gh_sess'] # BAh7Bzo...
browser.session.headers['User-Agent'] # a python robot

# Search the parsed HTML
browser.select('div.teaser-icon') # [<div class="teaser-icon">
# <span class="mega-octicon octicon-checklist"></span>
# </div>,
# ...
browser.find(class_=re.compile(r'column', re.I)) # <div class="one-third column">
# <div class="teaser-icon">
# <span class="mega-octicon octicon-checklist"></span>
# ...

RoboBrowser also includes tools for working with forms, inspired by
`WebTest <https://github.com/Pylons/webtest>`_ and `Mechanize <http://wwwsearch.sourceforge.net/mechanize/>`_.

.. code-block:: python

from robobrowser import RoboBrowser

browser = RoboBrowser()
browser.open('http://twitter.com')

# Get the signup form
signup_form = browser.get_form(class_='signup')
signup_form # <RoboForm user[name]=, user[email]=, ...

# Inspect its values
signup_form['authenticity_token'].value # 6d03597 ...

# Fill it out
signup_form['user[name]'].value = 'python-robot'
signup_form['user[user_password]'].value = 'secret'

# Submit the form
browser.submit_form(signup_form)

Checkboxes:

.. code-block:: python

from robobrowser import RoboBrowser

# Browse to a page with checkbox inputs
browser = RoboBrowser()
browser.open('http://www.w3schools.com/html/html_forms.asp')

# Find the form
form = browser.get_forms()[3]
form # <RoboForm vehicle=[]>
form['vehicle'] # <robobrowser.forms.fields.Checkbox...>

# Checked values can be get and set like lists
form['vehicle'].options # [u'Bike', u'Car']
form['vehicle'].value # []
form['vehicle'].value = ['Bike']
form['vehicle'].value = ['Bike', 'Car']

# Values can also be set using input labels
form['vehicle'].labels # [u'I have a bike', u'I have a car \r\n']
form['vehicle'].value = ['I have a bike']
form['vehicle'].value # [u'Bike']

# Only values that correspond to checkbox values or labels can be set;
# this will raise a `ValueError`
form['vehicle'].value = ['Hot Dogs']

Uploading files:

.. code-block:: python

from robobrowser import RoboBrowser

# Browse to a page with an upload form
browser = RoboBrowser()
browser.open('http://cgi-lib.berkeley.edu/ex/fup.html')

# Find the form
upload_form = browser.get_form()
upload_form # <RoboForm upfile=, note=>

# Choose a file to upload
upload_form['upfile'] # <robobrowser.forms.fields.FileInput...>
upload_form['upfile'].value = open('path/to/file.txt', 'r')

# Submit
browser.submit(upload_form)
