Ooh, thanks Tim, I'll test that tonight - would be nice to start editing on Chrome again, I'd forgotten just how frustrating the Firefox "wave mouse pointer around until the horizontal segment gets highlighted" issue was...

Bah humbug, Chrome is still a no-go zone

Tim's suggestion allows the OS data to be retrieved in Firefox without using the @require directive, but in its current form it doesn't appear to do anything in Chrome. However, Firefox testing threw up a much bigger issue - whereas @require caches the data locally during the script installation, this workaround downloads the data every time you (re)load the WME page, and at 120MB that's a lot of data to be grabbing every time you start up an editing session, or reload the page to kick WME back into life after it goes loopy again...

Thanks again for the suggestion Tim, but alas it's back to the drawing board as far as Chrome support goes, and back to editing in Firefox.

Haven't yet looked at Chrome compatibility again, been a little bit busy with other tweaks. Tonights update is therefore brought to you courtesy of three little words.

Bounding. Box. Visualisation...

The placement of the bounding box highlight is sometimes a bit off, but it's generally good enough to leave the user in no doubt as to which street name refers to the highlighted segment. If anyone notices the placement being significantly off in a certain area, please reply with a permalink and I'll see if I can fine tune the coordinate conversion.

Re: OS Open Data User Scripts

Thanks to the help given by Timbones, we're now good to go in Chrome

Note that in Chrome (and Firefox if you're using Noscript or some other scripting blocker), you'll need to allow scripting access to chizzum.com whilst in WME in order for the OS Locator data to be downloaded on the fly - you don't want to know how long it took me to realise why Tim's code didn't seem to be working, or the magnitude of the "doh" event once the penny finally dropped

In other news...

The city field is now genuinely ignored if it's blank - I'd always intended it to work this way (as one of my earlier posts implied), and now it does... It also no longer gets initialised to "null".

The bounding box highlight is now cleared whenever a new segment is highlighted.

Bounding box positioning has been tweaked slightly, and a minimum height/width limit of 20 pixels is now enforced to avoid visibility problems when the road segment defined by the box runs exactly or very nearly E-W or N-S

Re: OS Open Data User Scripts

Big if, since my hosting package doesn't already include SSL support and adding it on is way too costly. Unless someone has a much cheaper option for hosting the OS data on a SSL server, Chrome users will just have to remember to keep allowing insecure data access (for as long as Google continue to allow them to do that...)

Timbones wrote:It seems that Google are tightening up the security of Chrome. In the beta versions, you can no longer install scripts or extensions unless they come from the Chrome Web Store.

Not entirely true, although you can no longer drag and drop onto the main Chrome window, you can still drag and drop onto the Extensions tab.

Timbones wrote:Might have to stick to Firefox for editing...

...and if Waze could figure out a way to fix the horizontal segment selection bug, there'd be no reason to use anything other than Firefox for editing. Even with that bug, I now find myself doing pretty much all of my edits in FF, because all these security-related tweaks to Chrome are making it less appealing for scripting work.

Anyway, this topic bump has reminded me there's a long overdue update to the script ready for release... The changes of note compared with 0.8.4 are as follows:

Runs within the WME context, allowing direct access to WME functions and data without the need for unsafeWindow hackery (thanks to timbones for the code)

Uses the latest road name abbreviations list from the wiki

The bounding box now works with the aerial images layer

"Un-named segment" is now permanently available as a name choice - handy for filling in the details on new roundabouts...

Country/State fields are set to "United Kingdom" and "Other" if they aren't already (suggested by Dave2084)

Yeah, I'll be doing that soon, once I'm happy with the most recent tweaks - one or two more large-scale editing sessions should shake down the code nicely and get it ready for an 0.9 release over the weekend... After that I think I'll take a break from OS integration and spend some time playing around with a few other ideas I've been having to improve the editing process.

That rules me out then

I'll have another look at the available segment properties to see if there's an easy way to determine which segments correspond to a single roundabout, and if so whether it's possible to programmatically select them all, but no promises...

Yeah, I was hoping the visual marking of new roundabouts would be easy to pick out of the source code, but last time I looked into this it didn't seem to be at all obvious. Having said that, I've learned a bit more about how WME goes about its business since then, so perhaps I was overlooking something that time...

True, it won't work for messed up roundabouts, but I think the main use for this option would be to make it easier to correctly name (or not-name) a newly forged roundabout, to prevent it from ending up an annoying red blotch on the map.

As a little Friday diversion, with the OS data now neatly packaged into 10x10km squares, I wondered what a scatter plot of the filesizes would look like...

Not too much of a surprise I guess!

If people stop giving me last minute ideas, then I plan to do a release in the next 24 hours...
