"nikola build --pdb" doesn't

I tried to debug code in a theme. No such luck.

$ nikola build --pdb

How do I get at that value?

pdb won't really help you here; the Zen themes need special navigation
links configuration, and that's documented along those themes.

@Kwpolska I know that. This issue is not about the Zen-Jinja theme, which I'm modifing anyway (it doesn't have submenu navigation, which I want to add). This issue is about the ability to debug problems.

[Kwpolska]

I can reproduce, and this is a doit bug (also happens outside of Nikola). @schettino72, any ideas?

[schettino72]

I guess the docs are clear enough: http://pydoit.org/cmd_run.html#pdb
It is documented, so it is not a bug 😁

I agree that it would be an useful addition to debug exception in task execution too.
For that please create an issue (or better a PR) on doit tracker.
