Keep imports alphabetically sorted and their order homogeneous across
Python source files.
The isort project has more feature and is more active than the
flake8-import-order plugin.
Most issues caught were simply import ordering from the same module.
Where imports were purposefully placed out of order, tag with
isort:skip.
In Python 3, the default encoding of source files is utf-8. The encoding
cookie is now unnecessary and redundant so remove it. For more details,
see the docs:
https://docs.python.org/3/howto/unicode.html#the-string-type
> The default encoding for Python source code is UTF-8, so you can
> simply include a Unicode character in a string literal ...
Includes a fix for the flake8 header checks to stop expecting an
encoding cookie.
In 423bf7b, I tried to add fallback mechanism to ``python3``. But it breaks
the python3 highlighting on python2 environment.
This adds ``'default'`` to highlighting languages; it works like
``'python3'``, but fallbacks if failed Highlighting. And this removes
try-parse step from ``'python3'`` language. Now, it highlights regardless of
runtime environments. Thanks to Yoshiki SHIBUKAWA.
This changeset adds the `highlight_options` configuration value, which
specifies a dict of key-value pairs to pass to the Pygments highlighter
specified with `highlight_language`. For example, specifying
`highlight_options = {'funcnamehighlighting' : False}` for the 'php'
lexer will disable function name highlighting.
Both the HTML and LaTeX writers have been updated to include the
options when calling `highlight_block()`, as long as the currently
selected language matches what was set with `highlight_language`, i.e.
not when modified by `highlight::` or `code-block::` directives.
* rename a few test modules to make the names more consistent
* do not copy/use Sphinx from build/ (unnecessary without 2to3)
* use a temporary dir for *all* test projects, the source tree
will stay pristine that way (default is tests/build)
* speed up tests by ~3x by splitting up test projects and avoiding
rebuilds
