I've tried something similar but found it way too painful if the comments need to be long...

    # Never enable this config, because if you do the space-time
    # continuum will collapse into itself and the cloud servers
    # will disappear in a puff of steam. However, if you really
    # must enable it, remember that it's boolean and go read
    # TICKET-8675309 for the extensive list of side effects.
    TurboFactorRenoberation = false
...so people just end up writing stuff like:

    {
        "ConfigKeyComment": "TICKET-8675309",
        "ConfigKey": "TurboFactorRenoberation",
        "ConfigVal": false
    }
[edit]: formatting


That's not JSON anymore, that's pretty much enough to be considered a unique DSL. Scary that this is more or less required.


Almost all applications evolve their config files into unique DSLs over time. They may choose a generic serialization for the DSL's AST but it will end up being an underspecified application specific DSL regardless.
