semantically meaningful display outputs for notebooks¤

html is a data structure for visual information

    import jinja2, datetime; from IPython.display import HTML
    env = jinja2.Environment(loader=jinja2.DictLoader(templates := {}), extensions=["jinja2.ext.loopcontrols"]);
    env.globals.update(dispatch=(dispatch := {}))
    env.filters.update(dumps=__import__("json").dumps,**vars(__import__("builtins")))

import jinja2, datetime; from IPython.display import HTML
env = jinja2.Environment(loader=jinja2.DictLoader(templates := {}), extensions=["jinja2.ext.loopcontrols"]);
env.globals.update(dispatch=(dispatch := {}))
env.filters.update(dumps=__import__("json").dumps,**vars(__import__("builtins")))

template type dispatcher¤

for need to generate appropriate semantics for different data structures. we'll use a dispatching dictionary to handle that work. when int or float types are found then the numeric templates is used, str types use the string, list and dict handle sequences and containers.

function class module

    templates.update(
        numeric="""<data value="{{object|dumps}}"></data>""",
        time="""<time datetime="{{object.isoformat()}}">{{object}}</time>""",
        format="""{% for f, t in dispatch.items() %}{% if object | isinstance(t) %}{% include f %}{% endif %}{% endfor %}""",
        mapping="""<dl>{% for object, v in object.items() %}<dt>{% include "format" %}</dt><dd>{% set object = v %}{% include "format" %}</dd>{% endfor %}</dl>""",        string="""{% if "://" in object %}<a href="{{object}}">{{object}}</a>{% else %}<samp>{{object}}</samp>{% endif %}""",
        array="""<ol>{% for object in object %}<li>{% include "format" %}</li>{% endfor %}</ol>""",
        set="""<ul>{% for object in object %}<li>{% include "format" %}</li>{% endfor %}</ul>""",
    )
