how can I modify the file when I change the Config？

[lizhecao]

I found that there is not method such as ConfigFactory.writeFile ？how can I modify the .conf file after I use the withValue to get the new Config？

The library has limited support for that since it's made for hand-writtten config files.

There is a class ConfigDocument which has some limited API for changing the syntax tree.

There is also a render() method on config objects but it will not preserve formatting.

There is an open issue about adding more capability to ConfigDocument which is where enhancements to support writing files should go.

Another option is to keep a separate JSON file with machine edits rather than changing the .conf file.

Almost two years later and still no progress made on being able to write to configs. Common guys. What's a configuration implementation without support for writing to configs? 🥺

We need someone to work on this for it to happen!
