26
+ iniconfig: brain-dead simple parsing of ini files
27
+ =======================================================
28
+
29
+ iniconfig is a small and simple INI-file parser module
30
+ having a unique set of features:
31
+
32
+ * maintains order of sections and entries
33
+ * supports multi-line values with or without line-continuations
34
+ * supports "#" comments everywhere
35
+ * raises errors with proper line-numbers
36
+ * no bells and whistles like automatic substitutions
37
+ * iniconfig raises an Error if two sections have the same name.
38
+
39
+ If you encounter issues or have feature wishes please report them to:
40
+
41
+ https://github.com/RonnyPfannschmidt/iniconfig/issues
42
+
43
+ Basic Example
44
+ ===================================
45
+
46
+ If you have an ini file like this:
47
+
48
+ .. code-block:: ini
49
+
50
+ # content of example.ini
51
+ [section1] # comment
52
+ name1=value1 # comment
53
+ name1b=value1,value2 # comment
54
+
55
+ [section2]
56
+ name2=
57
+ line1
58
+ line2
59
+
60
+ then you can do:
61
+
62
+ .. code-block:: pycon
63
+
64
+ >>> import iniconfig
65
+ >>> ini = iniconfig.IniConfig("example.ini")
66
+ >>> ini['section1']['name1'] # raises KeyError if not exists
67
+ 'value1'
68
+ >>> ini.get('section1', 'name1b', [], lambda x: x.split(","))
69
+ ['value1', 'value2']
70
+ >>> ini.get('section1', 'notexist', [], lambda x: x.split(","))
71
+ []
72
+ >>> [x.name for x in list(ini)]
73
+ ['section1', 'section2']
74
+ >>> list(list(ini)[0].items())
75
+ [('name1', 'value1'), ('name1b', 'value1,value2')]
76
+ >>> 'section1' in ini
77
+ True
78
+ >>> 'inexistendsection' in ini
79
+ False

+ "description": "Jinja is a fast, expressive, extensible templating engine. Special\nplaceholders in the template allow writing code similar to Python\nsyntax. Then the template is passed data to render the final document.\n\nIt includes:\n\n- Template inheritance and inclusion.\n- Define and import macros within templates.\n- HTML templates can use autoescaping to prevent XSS from untrusted\n user input.\n- A sandboxed environment can safely render untrusted templates.\n- AsyncIO support for generating templates and calling async\n functions.\n- I18N support with Babel.\n- Templates are compiled to optimized Python code just-in-time and\n cached, or can be compiled ahead-of-time.\n- Exceptions point to the correct line in templates to make debugging\n easier.\n- Extensible filters, tests, functions, and even syntax.\n\nJinja's philosophy is that while application logic belongs in Python if\npossible, it shouldn't make the template designer's job difficult by\nrestricting functionality too much.",

41
+ description: |
42
+ Jinja is a fast, expressive, extensible templating engine. Special
43
+ placeholders in the template allow writing code similar to Python
44
+ syntax. Then the template is passed data to render the final document.
45
+
46
+ It includes:
47
+
48
+ - Template inheritance and inclusion.
49
+ - Define and import macros within templates.
50
+ - HTML templates can use autoescaping to prevent XSS from untrusted
51
+ user input.
52
+ - A sandboxed environment can safely render untrusted templates.
53
+ - AsyncIO support for generating templates and calling async
54
+ functions.
55
+ - I18N support with Babel.
56
+ - Templates are compiled to optimized Python code just-in-time and
57
+ cached, or can be compiled ahead-of-time.
58
+ - Exceptions point to the correct line in templates to make debugging
59
+ easier.
60
+ - Extensible filters, tests, functions, and even syntax.
61
+
62
+ Jinja's philosophy is that while application logic belongs in Python if
63
+ possible, it shouldn't make the template designer's job difficult by
64
+ restricting functionality too much.

+ # Jinja
28
+
29
+ Jinja is a fast, expressive, extensible templating engine. Special
30
+ placeholders in the template allow writing code similar to Python
31
+ syntax. Then the template is passed data to render the final document.
32
+
33
+ It includes:
34
+
35
+ - Template inheritance and inclusion.
36
+ - Define and import macros within templates.
37
+ - HTML templates can use autoescaping to prevent XSS from untrusted
38
+ user input.
39
+ - A sandboxed environment can safely render untrusted templates.
40
+ - AsyncIO support for generating templates and calling async
41
+ functions.
42
+ - I18N support with Babel.
43
+ - Templates are compiled to optimized Python code just-in-time and
44
+ cached, or can be compiled ahead-of-time.
45
+ - Exceptions point to the correct line in templates to make debugging
46
+ easier.
47
+ - Extensible filters, tests, functions, and even syntax.
48
+
49
+ Jinja's philosophy is that while application logic belongs in Python if
50
+ possible, it shouldn't make the template designer's job difficult by
51
+ restricting functionality too much.
52
+
53
+
54
+ ## In A Nutshell
55
+
56
+ ```jinja
57
+ {% extends "base.html" %}
58
+ {% block title %}Members{% endblock %}
59
+ {% block content %}
60
+ <ul>
61
+ {% for user in users %}
62
+ <li><a href="{{ user.url }}">{{ user.username }}</a></li>
63
+ {% endfor %}
64
+ </ul>
65
+ {% endblock %}
66
+ ```

+ """This class implements a bytecode cache that uses a memcache cache for
333
+ storing the information. It does not enforce a specific memcache library
334
+ (tummy's memcache or cmemcache) but will accept any class that provides
335
+ the minimal interface required.
336
+
337
+ Libraries compatible with this class:
338
+
339
+ - `cachelib <https://github.com/pallets/cachelib>`_
340
+ - `python-memcached <https://pypi.org/project/python-memcached/>`_
341
+
342
+ (Unfortunately the django cache interface is not compatible because it
343
+ does not support storing binary data, only text. You can however pass
344
+ the underlying cache client to the bytecode cache which is available
345
+ as `django.core.cache.cache._client`.)
346
+
347
+ The minimal interface for the client passed to the constructor is this:
348
+
349
+ .. class:: MinimalClientInterface
350
+
351
+ .. method:: set(key, value[, timeout])
352
+
353
+ Stores the bytecode in the cache. `value` is a string and
354
+ `timeout` the timeout of the key. If timeout is not provided
355
+ a default timeout or no timeout should be assumed, if it's
356
+ provided it's an integer with the number of seconds the cache
357
+ item should exist.
358
+
359
+ .. method:: get(key)
360
+
361
+ Returns the value for the cache key. If the item does not
362
+ exist in the cache the return value must be `None`.
363
+
364
+ The other arguments to the constructor are the prefix for all keys that
365
+ is added before the actual cache key and the timeout for the bytecode in
366
+ the cache system. We recommend a high (or no) timeout.
367
+
368
+ This bytecode cache does not support clearing of used items in the cache.
369
+ The clear method is a no-operation function.
370
+
371
+ .. versionadded:: 2.7
372
+ Added support for ignoring memcache errors through the
373
+ `ignore_memcache_errors` parameter.

151
+
152
+ Here are the possible initialization parameters:
153
+
154
+ `block_start_string`
155
+ The string marking the beginning of a block. Defaults to ``'{%'``.
156
+
157
+ `block_end_string`
158
+ The string marking the end of a block. Defaults to ``'%}'``.
159
+

+ `variable_start_string`
161
+ The string marking the beginning of a print statement.
162
+ Defaults to ``'{{'``.
163
+
164
+ `variable_end_string`
165
+ The string marking the end of a print statement. Defaults to
166
+ ``'}}'``.
167

+ `comment_start_string`
169
+ The string marking the beginning of a comment. Defaults to ``'{#'``.
170
+
171
+ `comment_end_string`
172
+ The string marking the end of a comment. Defaults to ``'#}'``.
173
+
174
+ `line_statement_prefix`
175
+ If given and a string, this will be used as prefix for line based
176
+ statements. See also :ref:`line-statements`.
177
+
178
+ `line_comment_prefix`
179
+ If given and a string, this will be used as prefix for line based
180
+ comments. See also :ref:`line-statements`.
181
+
182
+ .. versionadded:: 2.2
183
+
184
+ `trim_blocks`
185
+ If this is set to ``True`` the first newline after a block is
186
+ removed (block, not variable tag!). Defaults to `False`.
187
+
188
+ `lstrip_blocks`
189
+ If this is set to ``True`` leading spaces and tabs are stripped
190
+ from the start of a line to a block. Defaults to `False`.
191
+
192
+ `newline_sequence`
193
+ The sequence that starts a newline. Must be one of ``'\r'``,
194
+ ``'\n'`` or ``'\r\n'``. The default is ``'\n'`` which is a
195
+ useful default for Linux and OS X systems as well as web
196
+ applications.
197
+
198
+ `keep_trailing_newline`
199
+ Preserve the trailing newline when rendering templates.
200
+ The default is ``False``, which causes a single newline,
201
+ if present, to be stripped from the end of the template.
202
+
203
+ .. versionadded:: 2.7
204
+
205
+ `extensions`
206
+ List of Jinja extensions to use. This can either be import paths
207
+ as strings or extension classes. For more information have a
208
+ look at :ref:`the extensions documentation <jinja-extensions>`.
209
+
210
+ `optimized`
211
+ should the optimizer be enabled? Default is ``True``.
212
+
213
+ `undefined`
214
+ :class:`Undefined` or a subclass of it that is used to represent
215
+ undefined values in the template.
216
+
217
+ `finalize`
218
+ A callable that can be used to process the result of a variable
219
+ expression before it is output. For example one can convert
220
+ ``None`` implicitly into an empty string here.
221
+
222
+ `autoescape`
223
+ If set to ``True`` the XML/HTML autoescaping feature is enabled by
224
+ default. For more details about autoescaping see
225
+ :class:`~markupsafe.Markup`. As of Jinja 2.4 this can also
226
+ be a callable that is passed the template name and has to
227
+ return ``True`` or ``False`` depending on autoescape should be
228
+ enabled by default.
229
+
230
+ .. versionchanged:: 2.4
231
+ `autoescape` can now be a function
232
+
233
+ `loader`
234
+ The template loader for this environment.
235
+
236
+ `cache_size`
237
+ The size of the cache. Per default this is ``400`` which means
238
+ that if more than 400 templates are loaded the loader will clean
239
+ out the least recently used template. If the cache size is set to
240
+ ``0`` templates are recompiled all the time, if the cache size is
241
+ ``-1`` the cache will not be cleaned.
242
+
243
+ .. versionchanged:: 2.8
244
+ The cache size was increased to 400 from a low 50.
245
+
246
+ `auto_reload`
247
+ Some loaders load templates from locations where the template
248
+ sources may change (ie: file system or database). If
249
+ ``auto_reload`` is set to ``True`` (default) every time a template is
250
+ requested the loader checks if the source changed and if yes, it
251
+ will reload the template. For higher performance it's possible to
252
+ disable that.
253
+
254
+ `bytecode_cache`
255
+ If set to a bytecode cache object, this object will provide a
256
+ cache for the internal Jinja bytecode so that templates don't
257
+ have to be parsed if they were not changed.
258
+
259
+ See :ref:`bytecode-cache` for more information.
260
+
261
+ `enable_async`
262
+ If set to true this enables async template execution which
263
+ allows using async functions and generators.

+ As extensions are created by the environment they cannot accept any
63
+ arguments for configuration. One may want to work around that by using
64
+ a factory function, but that is not possible as extensions are identified
65
+ by their import name. The correct way to configure the extension is
66
+ storing the configuration values on the environment. Because this way the
67
+ environment ends up acting as central configuration storage the
68
+ attributes may clash which is why extensions have to ensure that the names
69
+ they choose for configuration are not too generic. ``prefix`` for example
70
+ is a terrible name, ``fragment_cache_prefix`` on the other hand is a good
71
+ name as includes the name of the extension (fragment cache).

1464
