UKTidalEvents Plugin

[Rasbats]

Thomas ...

On my Ubuntu 20.04 UKTides installs fine with the plugin manager. Downloads work correctly. Locations can be saved and recalled.

If present you could try removing 'tidalevents.xml' from the plugin data folder to see if that makes a difference.

Guidance on local builds and installing the dependencies is here:

Mike... What's the status of UKTides for OCPN v5.6, please?
It does not appear to be in the beta catalogue.

Tony ...

UKTidalEvents_pi is now in the master catalog for OpenCPN 5.6.0.

The manual has not yet been moved. TODO.

Ah! I have to uninstall whatever version I had (it was offering to downgrade) and then install and I then got the icon in the menu bar.

But clicking on the icon gets a OCPN crash. Looks like it is tripping on removing the old data file.

Can you try removing the old .xml data file? You may find two directories in opencpn/plugins.

opencpn/plugins/UKTides and opencpn/plugins/UKTides_pi.

Remove opencpn/plugins/UKTides if present.

In opencpn/plugins/UKTides_pi/data remove any .xml file. The next selection of a tidal station will re-make the tidalevents.xml file with the data for that station.

If opencpn/plugins/UKTides_pi/data does not exist that directory will be made when the plugin is used again.

No sign of plugins/UKTides.
plugins/UKTides_pi/data did not have any xml files.

I have deleted the UKTides_pi directory, uninstalled and reinstalled the plugin. This creates a new UKTides_pi directory.
Still the same crash on clicking the icon in the toolbar.

I have checked inside the OCPN application itself for detritus in the old place where plugin data used to go and there is nothing related to UKTides.

[Rasbats]

Thanks for the testing. I will work on this.

I think the problem arises from moving the plugin settings from [Settings] in the .ini file to [Settings/UKTides_pi].

On the Mac I removed the opencpn.ini file and the opencpn/plugins/UKTides_pi/data directory. Restarted OpenCPN. One warning about the previous crash and then everything worked correctly(?).

This is a bit dramatic. Suggest editing the .ini file. Remove any references to UKTides and save. Restart OpenCPN. Test the UKTides plugin. The settings (these include the dialog position) will be saved in [Settings/UKTides_pi] on closing OpenCPN.

No luck here...
I quit OCPN, deleted the UKTides [Settings/UKTides_pi] section and checked no other refers to UKTides apart from the dylib.
I then reinstalled the plugin (its v1.1.0) and enabled it and without clicking on the icon quit OCPN. Now it has created a new [Settings/UKTides_pi] section with

[Settings/UKTides_pi]
ShowUKTidesIcon=1
DialogPosX=20
DialogPosY=20

Then I launched OCPN again with UKTides being the only active plugin and clicked on the icon and got the same crash.

Tony ...

I will put a message on Slack.

Antipole found the issue. The problem happens when two or more stations are saved. Work needed for this situation.

Don't know if this is the right place for this.


I don't sail in UK waters but do have use for tides worldwide.


I have used Tide Comp 2000 from Pangolin.co.nz for many years.


Tides is now available as a download along with some other useful software and links. The site relies on donations. Would it be useful to adopt this as the source for O rather than the Admiralty data. Obviously this would require some cooperation from Pangolin.

The UKTides plugin uses official UKHO data using the UKHO API. Pangolin Tides covers the same range of locations in the UK. My concern is that these predictions are unoffical and not approved by UKHO.

Comparing the SHOM predictions for one French location showed a difference in time of 28minutes and 1 metre in height.

The main OpenCPN program uses santioned official tidal data.

Yes, see where you are coming from but at the end of the day they are all predictions. Just thought it would make tides available within O for the whole world.
Keep up the good work
