local initialized = false -- for only once lazy initialization
local FEED_CONFIG_FILE = "feeds.xml"
local FEED_CONFIG_FILE = "feed_config.lua"

File type/structure is lua, ok.

But can it have different extension - ".conf"?
E. G. "feed.conf", "feed_source.conf" etc, so it's explicitly seen that's user configuration file, not another developer file?
Does lua support that?

In terms of LUA vm, it just reads a stream of text and run the code, so extension doesn't matter. My concerns with .conf suffix are:

  • inconsistency naming between other existing configs like settings.reader.lua and all the metadata in sdr folders.
  • no indication of what config syntax is supported, i.e. when a user opens a .conf file, they won't be able to know what's the expected syntax.

Do you think it would good enough to have that _config part in the filename? In the long run, no one should be manually editing this file. The next iteration should add a UI for managing this config.

Ok. Let's keep it as is, as you're saying UI is not so far away.

-- list your feeds here:
-- only supports http URL for now
-- set limit to "0" means no download, "-1" no limit.
{ "http://www.huffingtonpost.com/feeds/index.xml", limit = 2 },

btw I think we should have at least 2 feed sources in our example config.
I'll add one.

It will introduce some minor noise, but too much stuff is simply not seen otherwise, for example:
