# Legacy EM
|
||
|
|
|
||
|
|
## Summary
|
||
|
|
|
||
|
|
The Legacy EM extension restores Markdown's original behavior for emphasis and
|
||
|
|
strong syntax when using underscores.
|
||
|
|
|
||
|
|
By default Python-Markdown treats `_connected_words_` intelligently by
|
||
|
|
recognizing that mid-word underscores should not be used for emphasis. In other
|
||
|
|
words, by default, that input would result in this output:
|
||
|
|
`<em>connected_words</em>`.
|
||
|
|
|
||
|
|
However, that behavior is not consistent with the original rules or the behavior
|
||
|
|
of the reference implementation. Therefore, this extension can be used to better
|
||
|
|
match the reference implementation. With the extension enabled, the above input
|
||
|
|
would result in this output: `<em>connected</em>words_`.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
See [Extensions](index.md) for general extension usage. Use `legacy_em` as the
|
||
|
|
name of the extension.
|
||
|
|
|
||
|
|
This extension does not accept any special configuration options.
|
||
|
|
|
||
|
|
A trivial example:
|
||
|
|
|
||
|
|
```python
|
||
|
|
markdown.markdown(some_text, extensions=['legacy_em'])
|
||
|
|
```
