digitalmars.D.learn - Persistent Storage

reply Mr. Pib <Af343 MS.com> writes:
Does D have a persistent storage somewhere? I'd like something 
easy to use that allows me to load and save settings to disk in 
between executions of the program. I want to specify the variable 
to be saved or loaded and a default value.

e.g.,

Persist_Load(Some_variable, 100);

will load Some_variable from disk. If the storage does not exist 
on disk it will use the value 100.

It should manage the variables internally so it knows what is 
what. I don't mind actually specifying some_variable as a string 
to do this or using mixins and templates to achieve this, but it 
should be a one liner thing.

Try a serialization library or inifiled. Some may even use a DB 
with ORM for this.

https://code.dlang.org/packages/inifiled
https://code.dlang.org/packages/jsonizer
https://code.dlang.org/packages/asdf
https://code.dlang.org/packages/yamlserialized

etc... there are much.

Thanks, I wrote my own quick version for what I need so I'll 
probably use that for now. In the future I might look in to those.
