werkzeug.debug.repr
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
This module implements object representations for debugging purposes.
|
|
Unlike the default repr these reprs expose a lot more information and
|
|
produce HTML instead of ASCII.
|
|
|
|
Together with the CSS and JavaScript files of the debugger this gives
|
|
a colorful and more compact output.
