[Bobronium]

This shifts error verbosity to reduce terminal output pollution

Current behaviour

• default: render error with source reference and solution if present
• CleoSimpleException: render it with just a message, never display solution
• io.is_verbose(): default + full stack trace

New behaviour

• default / CleoSimpleException: render error with just a message + solution if present
• io.is_verbose(): render error with source reference + solution if present
• io.is_very_verbose(): io.is_verbose() + full stack trace

In other words

• simple is enabled by default (whilst supporting solutions)
• verbose is now previous default (compact source reference)
• very_verbose is now previous verbose

@sdispater, please take a look when you'll have time

[sdispater]

What's the reasoning behind making the stack trace available only for the very verbose verbosity onwards? I would prefer to keep it at the verbose level.

Otherwise the rest looks good.

[Bobronium]

@sdispater, if it would be displayed on verbose, then there wouldn't be an option to show compact source reference anymore.

In current implementation, verbosity will gradually increase:

1. default — just message
2. verbose — source reference
3. very_verbose — full stack trace

If full stack trace is shown on verbose, we then loose option to just show source reference:

1. default — just message
2. verbose — full stack trace
3. very_verbose — full stack trace

I wouldn't want to loose such feature since it's sufficient in most cases, and when more needed — one can ask for more by -vv.

Thanks for the explanation, I somehow missed this subtlety.

Works for me then 👍

Seems like failed with pallets/click#2225,
Proposed a fix in #137

[Bobronium]

Is there anything preventing merging/releasing this?

[Secrus]

@Bobronium could you please fix pre-commit issues and rebase with current master?

[branchvincent]

@Bobronium do you mind rebasing this? We'll be releasing a new version soon and it would be great to include this

[Bobronium]

@branchvincent, no, I don't mind. I might get to this today or tomorrow.

[Bobronium]

@Secrus, @branchvincent, done!

[branchvincent]

thanks @Bobronium!
