traceback on missing configuration

[glyph]

I think Incremental moved from towncrier.ini to pyproject.toml and now I get this when I run it

Traceback (most recent call last):

(The config is moved in the incremental release candidate branch, but it would be nice to fix this for others upgrading.)

[hynek]

I don’t get it, what exactly would you like to have fixed? Do you want a better error message on missing config?

Note that I was planning to remove incremental from towncrier - #398 :) while still supporting projects using incremental.

[SmileyChris]

I've got an updated version of removing incremental here #491.

But the issue here is load.py shouldn't be assuming that config['tool'] has a towncrier section. This is fixed in my rewrite of parse_toml in #483

[SmileyChris]

Fixed now #483 is merged 🎉
