Interconnection with sinx stats aggregator

[Arteneko]

I built sinx a while ago, to simplify scheduled stats collection.

It's backed by a redis storage and a pretty simple UX, and I wanted to know your thoughts about providing a plugin to extract data from sinx right away.

Yes, that would be a nice example for out-of-tree plugin.

Sorry if I missed something, but how is that different from, well, querying redis directly (using, say, this library)?

Or do you want it to interact with sinx via the HTTP API? If so, we already have an example of such a widget.

[Arteneko]

I'm thinking about a module that interacts with redis but natively reads the configuration for the sinx tools, e.g. To auto-handle the user-configured sinx prefix.

OK, so do you have a command to get the prefix? Are there any other configuration variables that need to be read?

[Arteneko]

The prefix can be set in the configuration file, which can be found at the paths described [here](https://github.com/Arteneko/sinx/blob/master/README.md#configuration). By default, the prefix is `sinx`. The full key in redis is `<prefix>::<key>`.

Okay, so we can just parse the config file(s) using lua-toml, and then query redis using redis-lua.

You can implement this yourself if you want, or wait until I do it.

[Arteneko]

I may look into implementing this, but never really worked with Lua. If I start a poc before you do, I'll submit it for review so you can use it as a base to implement a clean version, I guess.

Yeah, that would be nice.

[Arteneko]

I have some issue with directly interacting with Redis, especially in the case in which the sinx instance is remote (I have this case).

I'm thinking of two things:

• using io.popen to execute the CLI-based sinx or a curl to tap the sinx-http daemon
• using a lua http library (dependency, not nice) to call the sinx-http daemon

How does this library handle lua dependencies on modules?
Is it up to the user to handle that?

luastatus is no library; rather, it is a platform.

Is it up to the user to handle that?

It’s up to Lua to handle that:

Lua uses the package library to manage modules.

package.path (for modules written in Lua) and package.cpath (for modules written in C) are the places where Lua looks for modules. They are semicolon-separated lists, and each entry can have a ? in it that's replaced with the module name.

luastatus just does not interfere with this, nor should it.

As for popen vs. lua http library, I would go for the http library — it’s quite easy to install it via luarocks.

Take a look at the following btc-price widget example: https://github.com/shdown/luastatus/blob/master/examples/i3/btc-price.lua

And at the imap plugin: https://github.com/shdown/luastatus/blob/master/plugins/imap/imap.lua

Thanks for the info about libraries, I'm still not familiar with the lua tool environment, but trying to learn.

As a side-note, using luastatus right now on my work laptop, it integrates nicely with i3!

Hearing such things is the ultimate reason to do open-source development :)
