If your processing one document at a time, the -functions will serve your needs. However, if you need to process -multiple documents, it may be advantageous to create a single instance -of the `markdown.Markdown` class and pass multiple documents through it. - -### `markdown.markdown(text [, **kwargs])` - -The following options are available on the `markdown.markdown` function: - -* `text` (required): The source text string. - - Note that Python-Markdown expects **Unicode** as input (although - a simple ASCII string may work) and returns output as Unicode. - Do not pass encoded strings to it! If your input is encoded, (e.g. as - UTF-8), it is your responsibility to decode it. For example: - - input_file = codecs.open("some_file.txt", mode="r", encoding="utf-8") - text = input_file.read() - html = markdown.markdown(text) - - If you want to write the output to disk, you must encode it yourself: - - output_file = codecs.open("some_file.html", "w", - encoding="utf-8", - errors="xmlcharrefreplace" - ) - output_file.write(html) - -* `extensions`: A list of extensions. - - Python-Markdown provides an API for third parties to write extensions to - the parser adding their own additions or changes to the syntax. A few - commonly used extensions are shipped with the markdown library. See - the extension documentation for a list of available extensions. - - The list of extensions may contain instances of extensions or stings of - extension names. If an extension name is provided as a string, the - extension must be importable as a python module either within the - `markdown.extensions` package or on your PYTHONPATH with a name starting - with `mdx_`, followed by the name of the extension. Thus, - `extensions=['extra']` will first look for the module - `markdown.extensions.extra`, then a module named `mdx_extra`. - -* `extension-configs`: A dictionary of configuration settings for extensions. - - The dictionary must be of the following format: - - extension-configs = {'extension_name_1': - [ - ('option_1', 'value_1'), - ('option_2', 'value_2') - ], - 'extension_name_2': - [ - ('option_1', 'value_1') - ] - } - See the documentation specific to the extension you are using for help in - specifying configuration settings for that extension. - -* `output_format`: Format of output. - - Supported formats are: - - * `"xhtml1"`: Outputs XHTML 1.x. **Default**. - * `"xhtml5"`: Outputs XHTML style tags of HTML 5 - * `"xhtml"`: Outputs latest supported version of XHTML (currently XHTML 1.1). - * `"html4"`: Outputs HTML 4 - * `"html5"`: Outputs HTML style tags of HTML 5 - * `"html"`: Outputs latest supported version of HTML (currently HTML 4). - - Note that it is suggested that the more specific formats ("xhtml1", - "html5", & "html4") be used as "xhtml" or "html" may change in the future - if it makes sense at that time. The values can either be lowercase or - uppercase. - -* `safe_mode`: Disallow raw html. - - If you are using Markdown on a web system which will transform text - provided by untrusted users, you may want to use the "safe_mode" - option which ensures that the user's HTML tags are either replaced, - removed or escaped. (They can still create links using Markdown syntax.) - - The following values are accepted: - - * `False` (Default): Raw HTML is passed through unaltered. - - * `replace`: Replace all HTML blocks with the text assigned to - `html_replacement_text` To maintain backward compatibility, setting - `safe_mode=True` will have the same effect as `safe_mode='replace'`. - - To replace raw HTML with something other than the default, do: - - md = markdown.Markdown(safe_mode='replace', - html_replacement_text='--RAW HTML NOT ALLOWED--') - - * `remove`: All raw HTML will be completely stripped from the text with - no warning to the author. - - * `escape`: All raw HTML will be escaped and included in the document. - - For example, the following source: - - Foo <b>bar</b>. - - Will result in the following HTML: - - <p>Foo <b>bar</b>.</p> - - Note that "safe_mode" does not alter the `enable_attributes` option, which - could allow someone to inject javascript (i.e., `{@onclick=alert(1)}`). You - may also want to set `enable_attributes=False` when using "safe_mode". - -* `html_replacement_text`: Text used when safe_mode is set to `replace`. - Defaults to `[HTML_REMOVED]`. - -* `tab_length`: Length of tabs in the source. Default: 4 - -* `enable_attributes`: Enable the conversion of attributes. Default: True - -* `smart_emphasis`: Treat `_connected_words_` intelegently Default: True - -* `lazy_ol`: Ignore number of first item of ordered lists. Default: True - - Given the following list: - - 4. Apples - 5. Oranges - 6. Pears - - By default markdown will ignore the fact the the first line started - with item number "4" and the HTML list will start with a number "1". - If `lazy_ol` is set to `True`, then markdown will output the following - HTML: - - <ol> - <li start="4">Apples</li> - <li>Oranges</li> - <li>Pears</li> - </ol> - - -### `markdown.markdownFromFile(**kwargs)` - -With a few exceptions, `markdown.markdownFromFile` accepts the same options as -`markdown.markdown`. It does **not** accept a `text` string. Instead, it accepts -the following required options: - -* `input` (required): The source text file. - - `input` may be set to one of three options: - - * a string which contains a path to a readable file on the file system, - * a readable file-like object, - * or `None` (default) which will read from `stdin`. - -* `output`: The target which output to written to. - - `output` may be set to one of three options: - - * a string which contains a path to a writable file on the file system, - * a writable file-like object, - * or `None` (default) which will write to `stdout`. - -* `encoding`: The encoding of the source text file. Defaults to - "utf-8". The same encoding will always be used for the output file. - The 'xmlcharrefreplace' error handler is used when encoding the output. - - **Note:** This is the only place that decoding and encoding of unicode - takes place in Python-Markdown. If this rather naive solution does not - meet your special needs, it is suggested that you write your own code - to handle your specific encoding/decoding needs. - -### `markdown.Markdown([**kwargs])` - -The same options are available when initializing the `markdown.Markdown` class -as on the `markdown.markdown` function, except that the class does **not** -accept a source text string on initialization. Rather, the source text string -must be passed to one of two instance methods: - -* `Markdown.convert(source)` - - The `source` text must meet the same requirements as the `text` argument - of the `markdown.markdown` function. - - You should also use this method if you want to process multiple strings - without creating a new instance of the class for each string. - - md = markdown.Markdown() - html1 = md.convert(text1) - html2 = md.convert(text2) - - Note that depending on which options and/or extensions are being used, - the parser may need its state reset between each call to `convert`. - - html1 = md.convert(text1) - md.reset() - html2 = md.convert(text2) - -* `Markdown.convertFile(**kwargs)` - - The arguments of this method are identical to the arguments of the same - name on the `markdown.markdownFromFile` function (`input`, `output`, and - `encoding`). As with the `convert` method, this method should be used to - process multiple files without creating a new instance of the class for - each document. State may need to be `reset` between each call to - `convertFile` as with `convert`. |
