Questions about spot API

  1. I think that "spot set <id> lifetime_seconds=<n>" sets the spot's expiration to n seconds after the "set" command is run, and not n seconds after the original "spot add" was run. This makes sense. Can I have confirmation please?
  2. It seems like there is some deduplication of spots internally — a "spot add" with the same rx_freq and callsign as an existing one will return the ID of the existing one instead of adding a new one. Could we know the exact rules that apply so that they can be documented in the wiki?

Thanks!

    1. Confirmed. The lifetime_seconds just sets a field and a timestamp is created and compared to the original spot timestamp to know when to eliminate that spot.
    2. The frequency/Callsign combo is considered unique. This note is in the source: 
    // Check to see if this Callsign-RXFreq combination is already in the DB
// If so - treat as a duplicate and simply update the fields in the spot

    Both of these clarifications should go into the wiki description, and I'll do what I can to get them updated. Thanks for pointing this out.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
