Usage
-----
-From the Python interpreter:
+See [Extensions](./index.html) for general extension usage, specify `codehilite`
+as the name of the extension.
- >>> html = markdown.markdown(text, extensions=['codehilite'])
+See the [Library Reference](../reference.html#extensions) for information about
+configuring extensions.
-To force every code block to have line numbers, even when using
-colons (`:::`) for language identification, set `linenums` to `True`.
+The following options are provided to configure the output:
- >>> html = markdown.markdown(text,
- ... extensions=['codehilite(linenums=True)']
- ... )
+* **linenums**:
+ Use line numbers. Possible values are `True` for yes, `False` for no and
+ `None` for auto. Defaults to `None`.
-To turn off all line numbers, even when using SheBangs (`#!`) for
-language identification, set `linenums` to `False`.
+ Using `True` will force every code block to have line numbers, even when
+ using colons (`:::`) for language identification.
- >>> html = markdown.markdown(text,
- ... extensions=['codehilite(linenums=False)']
- ... )
+ Using `False` will turn off all line numbers, even when using SheBangs
+ (`#!`) for language identification.
-To prevent Pygments from guessing the language (only highlighting
-blocks when you explicitly request it) set the `guess_lang` setting to `False`.
+* **guess_lang**:
+ Automatic language detection. Defaults to `True`.
- >>> html = markdown.markdown(text,
- ... extensions=['codehilite(guess_lang=False)']
- ... )
+ Using `False` will prevent Pygments from guessing the language, and thus
+ highlighting blocks only when you explicitly set the language.
-To assign a CSS class differant than the default ('codehilite') on the
-code's wrapping div, define a custom class with the `css_class` setting.
+* **css_class**:
+ Set CSS class name for the wrapper `<div>` tag. Defaults to
+ `codehilite`.
- >>> html = markdown.markdown(text,
- ... extensions=['codehilite(css_class=myclass)']
- ... )
+* **pygments_style**:
+ Pygments HTML Formatter Style (ColorScheme). Defaults to `default`.
+
+ !!! Note
+ This is useful only when `noclasses` is set to `True`, otherwise the
+ CSS style shall be provided by the end user.
+* **noclasses**:
+ Use inline styles instead of CSS classes. Defaults to `False`.
