        Installation
        ------------
        
        Pyppeteer requires python 3.6+.
        (experimentally supports python 3.5)
        
        Install by pip from PyPI:
        
        .. code-block::
        
           python3 -m pip install pyppeteer
        
        Or install latest version from `github <https://github.com/miyakogi/pyppeteer>`_\ :
        
        .. code-block::
        
           python3 -m pip install -U git+https://github.com/miyakogi/pyppeteer.git@dev
        
        Usage
        -----
        
        ..
        
           **Note**\ : When you run pyppeteer first time, it downloads a recent version of Chromium (~100MB).
        
        
        **Example**\ : open web page and take a screenshot.
        
        .. code-block:: py
        
           import asyncio
           from pyppeteer import launch
        
           async def main():
               browser = await launch()
               page = await browser.newPage()
               await page.goto('http://example.com')
               await page.screenshot({'path': 'example.png'})
               await browser.close()
        
           asyncio.get_event_loop().run_until_complete(main())
        
        **Example**\ : evaluate script on the page.
        
        .. code-block:: py
        
           import asyncio
           from pyppeteer import launch
        
           async def main():
               browser = await launch()
               page = await browser.newPage()
               await page.goto('http://example.com')
               await page.screenshot({'path': 'example.png'})
        
               dimensions = await page.evaluate('''() => {
                   return {
                       width: document.documentElement.clientWidth,
                       height: document.documentElement.clientHeight,
                       deviceScaleFactor: window.devicePixelRatio,
                   }
               }''')
        
               print(dimensions)
               # >>> {'width': 800, 'height': 600, 'deviceScaleFactor': 1}
               await browser.close()
        
           asyncio.get_event_loop().run_until_complete(main())
        
        Pyppeteer has almost same API as puppeteer.
        More APIs are listed in the
        `document <https://miyakogi.github.io/pyppeteer/reference.html>`_.
        
        `Puppeteer's document <https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#>`_
        is also useful for pyppeteer users.
        
        Differences between puppeteer and pyppeteer
        -------------------------------------------
        
        Pyppeteer is to be as similar as puppeteer, but some differences between python
        and JavaScript make it difficult.
        
        These are differences between puppeteer and pyppeteer.
        
        Keyword argument for options
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
        Puppeteer uses object (dictionary in python) for passing options to
        functions/methods. Pyppeteer accepts both dictionary and keyword argument for
        options.
        
        Dictionary style option (similar to puppeteer):
        
        .. code-block:: python
        
           browser = await launch({'headless': True})
        
        Keyword argument style option (more pythonic, isn't it?):
        
        .. code-block:: python
        
           browser = await launch(headless=True)
        
        Element selector method name (\ ``$`` -> ``querySelector``\ )
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
        In python, ``$`` is not usable for method name.
        So pyppeteer uses ``Page.querySelector()`` instead of ``Page.$()``\ , and
        ``Page.querySelectorAll()`` instead of ``Page.$$()``.
        Pyppeteer has shorthands for these methods, ``Page.J()`` and ``Page.JJ()``.
        
        Argument of ``Page.evaluate()`` and ``Page.querySelectorEval()``
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
        Puppeteer's version of ``evaluate()`` takes JavaScript raw function or string of
        JavaScript expression, but pyppeteer takes string of JavaScript. JavaScript
        strings can be function or expression. Pyppeteer tries to automatically detect
        the string is function or expression, but sometimes fails. If expression string
        is treated as function, and raise error, add ``force_expr=True`` option, which
        force pyppeteer to treat the string as expression.
        
        Example to get page content:
        
        .. code-block:: python
        
           content = await page.evaluate('document.body.textContent', force_expr=True)
        
        Example to get element's inner text:
        
        .. code-block:: python
        
           element = await page.querySelector('h1')
           title = await page.evaluate('(element) => element.textContent', element)
        
        Future Plan
        -----------
        
        
        #. Catch up development of puppeteer
        
           * Not intend to add original API which puppeteer does not have
        
        #. Add more tests and fix bugs
