High Performance Coder modified ticket #1894
Add Leap 16 to obsCheck and Ravel build targets
-
Centering Bug
-
Turns out that an upgrade to Cairo internals a few years ago means that rendering to a canvas of size 2e9 pixels squared fails, and has to be reduced to 2e6 pixels each side. I had come across this problem before in unrelated EcoLab work, but the change also needed to be done on one line in the Minsky codebase. The issue lurked in the background, hidden whilst I was using outdated versions of the library on MXE, only to be exposed when my computer's SSD died and the dev environment rebuilt as a consequence....

Godley Table Title Bug
-
Not sure how this happened - possibly in a AI agent commit, although nothing seems to have changed in the relevant code for a couple of years. Needed to add a "nameCurrentItem" call before popping up the dialog to collect the new title name.
-
Oh dear - bisect didn't really help. Building 3.18.4 from source code (on both Linux & Windows, Windows requiring adding -lgdi32 to the command line) gives the misbehaving version. Going back in time, current builds of older versions give misbehaving versions right back to when the code is no longer compilable with modern dev tools. What has changed from before to now is that my development system has had to be completely rebuilt after the SSD died. What has changed? Why just about everything, dammit!...

Steve Keen posted a comment on ticket #1896
There's an easy workaround: the Title option in the Godley window.

OK. I'll have to show the dilemma I experienced, once I stuff up enough to create it again.

You've reported this at https://sourceforge.net/p/minsky/tickets/1794/ and https://sourceforge.net/p/minsky/tickets/1787/ and maybe other places. This ticket is about something else entirely. In all the examples you sent of the "3 stooges problem", correcting the miscreant line fixed the problem - I never needed to edit the .mky file directly, nor even save and reload (a somewhat less egregious sin). So I'm at a loss as to what needs to be done.
-
True, but once that mistake is made, it should be possible to eliminate it within Ravel. Currently, it's not. Like the 3 Stooges rolling out a carpet, if you eliminate the erroneous row from one table, it reappears in another. The only way out at present is to identify the error and then eliminate the relevant text in the MKY file using a text editor.
-
I don't believe it is releated. This has to do with initial conditions being defined in terms of the variable. What you're talking about stems from a misunderstanding of signs between assets and liabilities, I believe.

Godley Table dropdown not working

OK - I gave this task to Github Copilot - it didn't do too bad a job, maybe about a 90% job, which I fixed up, then promptly refined with testing. Only question is whether the location of "Import stock variables" in the context menu is optimal.
-
That's a good thought. Users are used to the right-click menu of course, so adding one for when a user hovers over the stock name cell makes perfect sense. Ditto for flows. Here's a sample video for what I've like to make smoother still for future videos.: https://www.dropbox.com/scl/fi/qv8rdqgniycozgxhjq1fk/SelginError20251026ScreenOnly.mp4?rlkey=wd2nnxyzrxwvqz74qcspggiyd&dl=0 Views on YouTube are really taking off now, which is perfect timing for the seed round.
-
On the canvas at any rate - obviously there is that support in the Godley popup. Note there may be a solution of adding some support in the context menu. A bit of logic to code in Typescript, but might be a good job to give Github copilot. On Sun, Oct 26, 2025 at 09:10:52AM -0000, Steve Keen wrote: So you have to type stock names in then?

So you have to type stock names in then? No assistance from Ravel in knowing what they are?
-
That's because the triangle wedges are vestigial items left over from when the code supported the Godley popup window. Since Niel's refactor of the Godley popup, they're not needed. It is not feasible to have the canvas drive menus. The wedges should be removed from the edit mode tables. -- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders hpcoder@hpcoders.com.au http://www.hpcoders.com.au

Finally got this to work, and tested on Linux Mint. So upgrading to ravel should work from version 3.19 for other distros other than our directly supported distros, provided you can get a version of Minsky that runs.

Correspondence copied from Patreon chat: Thanks - yes I was able to reproduce this issue on both the 3.19 beta and the latest 3.18 release on MacOS. Conversely, this issue doesn't present when running the software on Linux. I'm not able to test this on Windows ATM. Would it be possible for you to raise a bug report at https://sourceforge.net/p/minsky/tickets/ so this gets tracked and fixed. Also, if possible, could you try earlier versions of Ravel to see if this is a regression

I have worked around this by building postgresql on a native installation of MXE, then copying the binary artifacts to the docker container.

Again workarounds exist, as this functionality does work when called from the context menu.

Something went wrong previously with the attachment. This is what it is supposed to be.

Not if you set the display format to %Y-%b or %Y-%m. To get that display, you still have the format incorrectly set to %Y-%Q
-
Yeah, but it's a chore. I'd rather we supported multiple formats in the one dimension, with Ravel handling the underlying time dimensions seamlessly between different formats. Until then, if one format only is supported, then that format is imposed on subsequent Ravels with the same time dimension. For quarterly data (Debt) followed by monthly data (House Price Index), the quarterly elements of the monthly data would be imported and the non-quarter months (1-2,4-5,7-8, 10-11) dropped. On Sun, Aug...
-
As the software currently stands, you can import the monthly and annual series separately, using formats %m/%Y and %Y respectively, then write out the series as separate CSV file using Ravel's export to CSV feature.
-
RVL file.
-
Yes there is! See the attached screenshot (model to come in the next comment). This process still results in 12 quarters per year, and the associated "chunky" plots where three potentially different values--from different months--are stacked on top of each other. We need to map from months to quarters (and all other date transformations) properly. The simplest here would be to impose quarters on the correct months (3=Q1, 6=Q2, 9=Q3, 12=Q4) and drop the other months. That would do at present. At a...
-
Note formats with only %Y %y %m %d %H %M %S and nothing else can handle can handle missing fields. The fields are filled in the order specified - maybe it should be modified to accept y m d h m s preferential order in the event that fewer fields are provided in the input - sort of like %d %m %Y and if that doesn't match then %m %Y and if that doesn't match %Y
-
Date Formats
-
I'm not sure what you mean by "new user". These data files are sufficiently complex, it would take someone who's been around the traps to navigate their complexity. As it was, I noticed you had the display format for Date set to %Y-Q%Q, which is not appropriate for monthly data. So I changed that to %Y-%b. Then I noticed you had somehow reset all the dates to quarters - not sure how you did that, so I had to reimport the LONG_CPI file, using the blank format. This of course adds an extra handle for...
-
A suggestion: add a multi-plot widget. Options would include how many series to plot per chart (default 1). The output could be a frame which can be resized containing the number of generated charts, which the user could resize. Or an option could be layout 2x5, 3x3, etc. This would be a useful feature to add for the first commercial release if we get seed funding.
-
I know I could have started importing the first two files without specifying a date format, and then the 3rd could have imported fine with the DMYT underlying format. But a new user will not know that. Here's the Excel-edited file which should import fine now; we should enable the automatic creation of this in Ravel.

Failed to find shared library for backend sqlite3
-
Thanks Joel. I have now enabled those backends in MacPorts, updated the documentation for setting up a production build, and edited the script that creates the release bundle to include all available SOCI backends. Now, it appears the Windows production build has exactly the same problem, so I'll need to do the equivalent there. Finally, it would be nice to obtain a list of available backends at runtime, and populate the drop menu with just those backends.

It probably is--just a more extreme example.

Name command on import

Only happens if you click on the newly created parameter. So I've created additional logic to handle the case the user does that. If you click on any other canvas item, then all bets are off - the rename just will not happen, as the system has lost sight of what it is that is being loaded.
