It either - has to return a string or markup object. - 2. if an object has an ``__html__`` method it is called. - 3. otherwise the default format system of Python kicks in and the result - is HTML escaped. - - Here is how you can implement your own formatting: - - .. code-block:: python - - class User(object): - - def __init__(self, id, username): - self.id = id - self.username = username - - def __html_format__(self, format_spec): - if format_spec == 'link': - return Markup('{1}').format( - self.id, - self.__html__(), - ) - elif format_spec: - raise ValueError('Invalid format spec') - return self.__html__() - - def __html__(self): - return Markup('{0}').format(self.username) - - And to format that user: - - .. code-block:: python - - >>> user = User(1, 'foo') - >>> Markup('

User: {0:link}').format(user) - Markup(u'

User: foo') - - Markupsafe supports Python 2.6, 2.7 and Python 3.3 and higher. - -Platform: UNKNOWN -Classifier: Development Status :: 5 - Production/Stable -Classifier: Environment :: Web Environment -Classifier: Intended Audience :: Developers -Classifier: License :: OSI Approved :: BSD License -Classifier: Operating System :: OS Independent -Classifier: Programming Language :: Python -Classifier: Programming Language :: Python :: 3 -Classifier: Topic :: Internet :: WWW/HTTP :: Dynamic Content -Classifier: Topic :: Software Development :: Libraries :: Python Modules -Classifier: Topic :: Text Processing :: Markup :: HTML diff --git a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/SOURCES.txt b/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/SOURCES.txt deleted file mode 100644 index 210b339ce..000000000 --- a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/SOURCES.txt +++ /dev/null @@ -1,18 +0,0 @@ -AUTHORS -CHANGES -LICENSE -MANIFEST.in -README.rst -setup.cfg -setup.py -tests.py -MarkupSafe.egg-info/PKG-INFO -MarkupSafe.egg-info/SOURCES.txt -MarkupSafe.egg-info/dependency_links.txt -MarkupSafe.egg-info/not-zip-safe -MarkupSafe.egg-info/top_level.txt -markupsafe/__init__.py -markupsafe/_compat.py -markupsafe/_constants.py -markupsafe/_native.py -markupsafe/_speedups.c \ No newline at end of file diff --git a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/dependency_links.txt b/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/dependency_links.txt deleted file mode 100644 index 8b1378917..000000000 --- a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/dependency_links.txt +++ /dev/null @@ -1 +0,0 @@ - diff --git a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/installed-files.txt b/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/installed-files.txt deleted file mode 100644 index 22e67eaa9..000000000 --- a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/installed-files.txt +++ /dev/null @@ -1,15 +0,0 @@ -..\markupsafe\_compat.py -..\markupsafe\_constants.py -..\markupsafe\_native.py -..\markupsafe\__init__.py -..\markupsafe\_speedups.c -..\markupsafe\__pycache__\_compat.cpython-36.pyc -..\markupsafe\__pycache__\_constants.cpython-36.pyc -..\markupsafe\__pycache__\_native.cpython-36.pyc -..\markupsafe\__pycache__\__init__.cpython-36.pyc -..\markupsafe\_speedups.cp36-win_amd64.pyd -dependency_links.txt -not-zip-safe -PKG-INFO -SOURCES.txt -top_level.txt diff --git a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/not-zip-safe b/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/not-zip-safe deleted file mode 100644 index 8b1378917..000000000 --- a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/not-zip-safe +++ /dev/null @@ -1 +0,0 @@ - diff --git a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/top_level.txt b/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/top_level.txt deleted file mode 100644 index 75bf72925..000000000 --- a/website/web/Lib/site-packages/MarkupSafe-1.0-py3.6.egg-info/top_level.txt +++ /dev/null @@ -1 +0,0 @@ -markupsafe diff --git a/website/web/Lib/site-packages/Werkzeug-0.14.1.dist-info/DESCRIPTION.rst b/website/web/Lib/site-packages/Werkzeug-0.14.1.dist-info/DESCRIPTION.rst deleted file mode 100644 index 675f08d10..000000000 --- a/website/web/Lib/site-packages/Werkzeug-0.14.1.dist-info/DESCRIPTION.rst +++ /dev/null @@ -1,80 +0,0 @@ -Werkzeug -======== - -Werkzeug is a comprehensive `WSGI`_ web application library.

The application will work even with `__name__`, thanks - to how resources are looked up. However it will make debugging more - painful. Certain extensions can make assumptions based on the - import name of your application. For example the Flask-SQLAlchemy - extension will look for the code in your application that triggered - an SQL query in debug mode.
