This is the list comprehension that is failing to generate tags:

Removing the condition fixes the bug. Works in my fork:

Do you want me to open a PR for this? Any reason why we need that extra code in the list comprehension?

[vaab]

Hum, you probably just forgot to tune your .gitchangelog.rc to set the tag_filter_regex.

https://github.com/vaab/gitchangelog/blob/master/src/gitchangelog/gitchangelog.rc.reference#L153

By default, the regexp does not match vXX.XX tags, but only the XX.XX (without the V).
Tell me if this solves your problem, and if yes, I would be interested to know how you missed that and if you have any suggestion to where or how I could document it, I would be happy to move forward on that point.

[miroswan]

A few issues:

• I didn't forget. I didn't see it at all. I personally find it odd that you would have to configure something like this in order to get what I would consider to be desirable default behavior
• Many projects prefix their tags with v. I won't be the only person to try out gitchangelog, wonder why this isn't working, then have to figure out how to get behavior as advertised in the README
• It looks like you're trying to set the default behavior to enforce a subset of the semantic versioning spec. If it's not going to be spec compliant, why have a default at all?

Anyway, those are my thoughts. I will try configuring this in the config file. Thanks for the tip.

Create a .gitchangelog.rc in your repo based on this repo .gitchangelog.rc.
And just repace around line 150:

tag_filter_regexp = r'^[0-9]+\.[0-9]+(\.[0-9]+)?$'

By :

tag_filter_regexp = r'^v[0-9]+\.[0-9]+(\.[0-9]+)?$'

Done !
