Re: [Wrapper-user] Please add "JSON" to logging format

[Karthik K. V. <kar...@gm...>]

It's a good idea, but I have these ideas on them:

- JSON isn't an appendable format, and this sort of log will not be well
formed JSON.
- CSV and YAML are good ideas - and they do support incremental updates and
parsing libraries are available.
- TXT files do allow appending and incremental updates are possible -
except, they require escaping \n s in Exceptions etc.
