Yes, I know, I've found most of those. I'm really asking for help in
choosing which to use. I think I can reject some quite quickly:-
ini - doesn't work so well with lists/dictionaries (though possible)
csv - rather difficult to edit
json - one of the most likely possibilities, but prefer yml
yml - front runner if I go for configuration files
xml - horrible, nasty to edit, etc. I don't like XML! :-)
pickle - not user editable as I understand it
dbms - current solution in sqlite3 as described
What I'm really asking for is how to choose between:-
DBMS - present solution, keeps config with data easily but more
code and less easy to change
yml - easy to edit config, keeps data separate from code but needs
YAML installed and separate files to manage
python - just keep config in the modules/classes, not easy to use
at 'both ends' (home and remote), otherwise quite simple
My requirements are:-
Easy to change, i.e.human readable format which can be edited
simply as I have to do this via a terminal/ssh.
Easy to use at local end as well as remote end, the remote end is
where it lives and is the 'driver' as it were but I need to know
the configuration at the local end as well.
