Toggling WebParser Contents

Post by Seahorse »

I am tinkering with an Instagram skin, I am parsing a feed for 8 items in a StringIndex perfectly happily and the quick & dirty test skin works but clearly needs some tweaking (later):

What I want to do is toggle through the first 5 images (5 x 8=40) in a slideshow fashion. The current approach would mean the parse would pull 40 items including images, I could then use a timer to toggle the next image (and 8 items) which seems simple enough.

Thinking about it this seems a clunky way of doing it, particularly maintaining a large webparse and the number of !bangs it would involve.

What I am after is a more efficient approach which is where I would appreciate some input :thumbup:

This is going to be something that is relatively easy in Lua, you will only need 1 WebParser measure and 5 meters.

It would be easier if you can post at least the URL and RegExp you are using to get the 40 captures though, so I don't have to re-invent the wheel.

Take a look also in my GoogleReaderTiny.lua script (inlcuded in Edge), it includes cycling over feed items. Or let jsmorley do it. :p ;-)

kreacher - I'll take a look thanks.

Ok, give me a little while to work up an approach in Lua for this. Check back in a half hour or so.

To be sure I get this, you want to have a slideshow that toggles between 5 items from the site on some timed basis, and what you are trying to avoid is having to create 40 child measures (in order to get the 8 data elements for each item) and keep the number of meters to a minimum?

You are going to display 1 "item" at a time... Right?

This is a slideshow for the current 5 popular images, the feed has like 15 or so. Each image has Child 8 measures which I gave descriptive names.

Whilst I can write 40 and do 8 !bangs every minute let's say, it seems a long winded approach that would be hard to maintain/debug.

I think you are going to be stuck with 41 WebParser measures no matter what. This site can't really be fully parsed in Lua, as it is returning Chinese or Korean or Japanese character sets in the results for "title", and Lua won't support parsing out strings that contain 2-byte unicode characters. So you will need the main WebParser and the 40 child measures. What we can do however is to use Lua to reduce the meters to just 8 or whatever is needed to display one "item", and have a counter to slideshow them using the single set of meters by having Lua read the appropriate child measures and just set !SetOption bangs to the meters.

Does that sound like something you want to tackle?

Was intending to use a counter to trigger 8 bangs using 8 meters only, as lua still makes my head spin and lua doesn't simplify it, I'll continue with the existing approach, thanks for the assistance... :welcome:

That's fine. It's not a terribly complicated Lua script, just 7 or 8 lines really, but since we need to do all the measures in Rainmeter anyway to avoid the 2-byte character unicode issue, it might be just as easy to do the meters in Rainmeter as well with a counter and some !SetOption bangs.

Good luck.
