API for fetching bindings, assignments, etc.?

Are there plans to extend the API to allow retrieving the current keybinding, 'assign' directives, etc.? In other words, recover all aspects of i3's configuration from the ~/.i3/config file and any subsequent changes made through i3-msg and friends?

If there aren't, would this be a non-goal? Or something that could be submitted?

Thanks!

I'm not an i3 developer, but I would tend to think that this would be a lot of effort for an unclear goal. What would your application of this kind of feature be? Perhaps we can suggest other solutions?

It is not possible to change any of *i3's* configuration options with `i3-msg`. With the exception of `i3-msg reload` and `i3-msg restart` of course, but that just loads the settings from the configuration file. So you really could only retrieve the settings that are in the config file anyway.

Retrieval is all I want at this point. And I'd rather not re-invent the parser since it's already been done.

There are no set goals for this, but that is because i3 doesn't have a roadmap at all. i3 is contribution-driven, so you can suggest features and either implement them yourself or wait for someone else to do it (assuming they will be accepted).

A few weeks ago we were talking about an issue and it came up that we could add a message type to retrieve the current bindings. Michael stated that he'd be open to that. So at least that would very likely be merged. For any other information you want through the IPC, I suggest opening a feature request on github and see what the feedback is.

However, you should have usecases in mind (and explain them). We won't be adding features on the off-chance that they might be useful some day in the future.

Also note that most changes that are done through i3-msg (or any other IPC implementation) only affect the tree and not the configuration. So querying the tree will already give you a ton on information about the current state. So again, please explain your usecases for this – and also what informaiton exactly you would need.

Reasonable enough. :-) (Whoa, character limit!) Scripting for dock/undock/variable-output situations; recovery of settings if `.i3/config` is lost, *etc.*. I'm scripting with ERB and a YAML file updated whenever `xrandr` outputs change.

Sorry, I meant describe usecases when filing the feature request. I don't think "I lost my config file at runtime and need to recover it from the running session" is a usecase, though. Just back up your config.

For the scripting part I don't quite understand why you need to recover information from i3? And either way, I think it's fairly unlikely that you will have the ability to receive *all* config directives through the IPC anytime soon. I really don't quite understand your usecase yet, though.
