IPython qtconsole ignores PromptManager change

Question

I edited ipython_qtconsole_config.py to include a timestamp:

import datetime
c = get_config()
c.PromptManager.in_template = '%s In [\\#]: ' % datetime.datetime.now().strftime("%H:%M:%S")

When I type config PromptManager in the shell I see that my change was made, however no timestamp is displayed. How can I fix this issue?

Answer 1

The qtconsole prompt doesn't support most of what the regular IPython prompt does (which is an open issue). The configurable is also different.

The default value:

c.IPythonWidget.in_prompt = 'In [<span class="in-prompt-number">%i</span>]: '

You can change it with:

c.IPythonWidget.in_prompt = '<b><i>My Prompt </i>[%i]: </b>'

When the issue is addressed, it should behave exactly as you expect.
