exception names are too limited about ameba

[Sija]

Yeah, in the same time rescue ex has 6.9k occurrences (~10x more than rescue exc) - i.e. all other uses are pretty marginal. I'm gonna add error to the defaults though, since it was unaccounted for.

thanks mate!

Perhaps use cases such as ex_ prefix could be enabled with regex matching support?

I feel like this should include version common names like error

It's not that common, therefore I didn't include it.
You can add it to your project's .ameba.yml file.

it should probably add something like || begins_with?("#{allowed}_") so nested exceptions can be handled like ex_parse ex_io etc

I disagree, exception variables should IMO have unified names.

Also e is not very descriptive ...

IMO it is - in the same way i (for index) is.

... and breaks other rules like descriptive block naming.

It shouldn't, since it's explicitly whitelisted:

ameba/src/ameba/rule/naming/block_parameter_name.cr

Line 31 in 47088b1

allowed_names %w[_ e i j k v x y ex io ws op tx id ip k1 k2 v1 v2]

Seem pretty commonly used

more common than rescue exception

also missing exc which is also quite commonly used
