Weather skin RegEx error.

[sl23]

It's been working for around 2-3 years now, but all of a sudden it's stopped showing the current temperature and looking at the log I have two errors:
1. Just says "Something Went Wrong"
2. RegExp matching error (-1) (RM\Weather\Weather.ini - [mWeatherParent])

I haven't changed anything and I have no knowledge of how RegEx works. Would somebody please tell me what's happened and how to fix? Thank you so much.

Here's the code in two separate files:

Change the variable WeatherAPIKey=21d8a80b3d6b444998a80b3d6b1449d3 to WeatherAPIKey=71f92ea9dd2f4790b92ea9dd2f779061 in WeatherParser.ini, then save and refresh the skin.

oh excellent! Thank you
Out of curiosity, why does this change every now an then?
How do I find this info to update it in future?

You'd have to ask the folks at weather.com why, as they are the ones changing the key. My guess is they do it intentionally to disrupt anyone who is using their key for free instead of paying for it. Their business model is to drive people to their website so they can shove ads in people's faces, and not to support people bypassing ads and grabbing their data without paying for it. Cross your fingers that they don't start changing the key EVERY DAY.

The easiest way to find the key is to let folks in the community find it and post it here.

(Code removed) There are ways, but it is better just to update the variable

Cross your fingers that they don't start changing the key EVERY DAY.

Currently, they seem to change it gradually by region, since, if you look in the forum, the present key was actually posted earlier than these last few days (if I'm not mistaken, eclectic-tech did it in Jan this year). This is somewhat similar to how they migrated from V2 to V3 back when we were struggling with both versions. Me, I'm more interested that they keep the JSON embedded in the page itself, so standard parsing of it can be used as a fallback without needing a key at all. A bit more work with the backslash escaping, but worth it as a plan B.

I didn't know it was a paid for service! I thought it was free. Makes sense now why it keeps changing.

You can try this code to display the current APIKey used by TWC (until they make another change )

This would be a nice snippet to incorporate into a skin to allow it to "self-heal" in the event of a key change.

Yes! I have added this (not "self-healing") but easy to use methods in a few of my skins.

The Access suite can update the APIKey by clicking a label in the settings skin.
The Weatherview skin includes a GetAPIKey.ini skin that will update the APIKey value when you load it.

Feel free to look at the code for either method of adding this feature to your weather skin.

I personally would advise against publishing all the details about that on a large scale, because of this, but as you wish. I mean, it's nice and everything, but it reveals our how-to (and not just our what-with) in a way that makes it trivial to stop it. An InputBox where you can enter the key should be more than enough for most users...
