Mapiah v0.2.39 - The Seeds of Love release
by Rodrigo Severo 06 Mar '26

06 Mar '26

Hi, Just release Mapiah version 0.2.39 - The [Seeds of Love](https://youtu.be/VAtGOESO7W8) release. Hopefully this release will be accepted by Flathub so Flatpak users will finally be able to run Therion from Mapiah. The other packages - Liux/AppImage, MacOS and Windows could do it since version 0.2.37 but neither 0.2.37 nor 0.2.38 were accepted by Flathub for "security issues", i.e., Mapiah was trying to call an external app, Therion. To solve this issue I had to bundle Therion inside Mapiah Flatpak package. It seems as an abomination to me but I am trying to see if it works well enough for me to keep doing it. As far as my tests show, it is working but Therion is way slower inside Mapiah Flatpak package. This might be solvable. Lets see what the future brings us. # Changelog ## 0.2.39 - 2026-03-05 - [The Seeds of Love](https://youtu.be/VAtGOESO7W8) release * New features: * Created keyboard shortcuts to run Therion: Ctrl+T (choose THConfig file and run Therion) and T (run Therion). * Showing PLA type and subtype at PLA overlay window. * Setting PLA type and subtype at PLA overlay window. * Element type showing also subtype on multiple elements clicked overlay window. * Flathub/flatpak release running embedded Therion. * Fixed bugs: * THConfig select file dialog not accepting common thconfig files. [reported by CaverBruce (issue [#16](https://github.com/rsevero/mapiah/issues/16))] * PLA types of created elements not added as last and most used types. * Creating new line with a subtype throws. * Test 3400 failing. * Test 3500 failing. * Unknown subtypes shown as internal subtype ID (all user type subtypes). * Setting subtype should update the last used subtype for the PLA type. * Infrastructure maintenance: * Converted MPGeneralController to a MobX store. * Created MPButtonTypes chooseTHConfigAndRunTherion and runTherion to run Therion. * Created TH2FileEditcontroller.getTHFileWidgetBuildContext(). * Removed unused methods from TH2FileEditElementEditController. * Created addPoint() method in TH2FileEditElementEditController. * Monitoring subtypes with last used PLA types. * flutter upgrade to 3.41.3 * flutter pub upgrade --major-versions * Embedding Therion (and its dependencies) in Flathub/Flatpak release. Please keep reporting any issues. Regards, Rodrigo Severo

Mapiah version 0.2.36 released - The Danaids release
by Rodrigo Severo 24 Feb '26

24 Feb '26

Hi, I have just released Mapiah version 0.2.36. It's available at https://github.com/rsevero/mapiah/releases/tag/v0.2.36 as usual. Mapiah is in fast development stage, but it is already usable for real mapping work. It is being used by the author and some other people to map real caves, and it is already being used in some caving courses. If you have TH2 files you want to edit and want to give Mapiah a try, please do. If you find any issue, please report it as a [Mapiah Issue](https://github.com/rsevero/mapiah/issues). ## 0.2.36 - 2026-02-24 - The [Danaids](https://en.wikipedia.org/wiki/Danaids) release * New features: * Allow multiple "add line segment" operations in sucession. [requested by Edvard] * Create shortcut to toggle all images visibility (keyboard shortcut Ctrl+I). * Show (and edit) orientation and lsize on the line points during edit. * Fixed bugs: * Main README.md file stills mentioning the web version of Mapiah, which was removed in 0.2.31 [reported by CaverBruce at issue [#13](https://github.com/rsevero/mapiah/issues/13)] * Slash produced by keyboard combinations (for example, AltRght + Q) is not processed as a shortcut to add line segments between selected line segments. * When adding line segments through keyboard shortcut '/', if there are no adjacent line segments selected, Mapiah throws instead of just doing nothing. [reported by Edvard] * Parsing scrap scales with 8 numbers but no unit failed. [reported by CaverBruce as issue [#15](https://github.com/rsevero/mapiah/issues/15)] * Undo of Bézier curve line segment addition with keyboard shortcut '/' not working. * Parsing scrap projection value in brackets failing. [reported by CaverBruce as issue [#14](https://github.com/rsevero/mapiah/issues/14)] * Creating a line and making one of its points smooth by overlay option window throws. * MPNumericAux directionOffsetToDegrees() and normalFromTangent() returning wrong values for some directions. * Fixing popcorn point type translation. [reported by Daniel Bean] * LSize and Orientation arrows not presented when end point is selected. * Interactive Orientation arrow not moving with azimuth picker arrow is moved. * Azimuth picker arrow not moving when interactive orientation arrow is moved. * LSize text value in lsize option window does not change when lsize is interactivelly changed. * LSize interactive arrow size does not change when LSize text value in lsize option window changes. * Infrastructure maintenance: * Testing all possible variations of scrap scale option parsing. * Custom exceptions should provide trace. * Renaming _execPrePrepareUndoRedoInfo and _execPreCreateUndoRedoCommand at MPCommand. * Creating MPAddLineSegmentCommand.atExistingLineSegmentPosition(). * Removing all references to web version. * Making custom exceptions be presented by showUnhandledErrorDialog() at main.dart. * Remove stack trace from THBaseException as showUnhandledErrorDialog() at main.dart already presents the stack trace. * Applying dart fix --apply to all code. * Flutter upgrade to 3.41.2 * flutter pub upgrade --major-versions * Created TH2FileEditElementEditController.optionTypeBeingEdited. * Add keys to radio groups at MPPLATypeOptionsOverlayWindowWidget. * Created 3500-ui_change_line_type_test. * Separating THLSizeOrientationPainter from THLinePainter. * Single action to set both LSize and Orientation values at TH2FileEditElementEditController. * MPNumericAux.averageTangent() method to calculate the weighted by segment length average tangent of two line segments. * Using lsize and orientation behaviour inspired by xThreion original one. * LSize and orientation interactive arrow should appear immediately when starting to set either of them. * Reusing Path created to draw compass arrow to also fuel the click test at MPTH2FileEditStateEditSingleLine. * Decimal places for double to string conversion of LSize and Orientation options as constants.

Difference of length in legend and statistics
by Martin Kern 14 Feb '26

14 Feb '26

Hello, Is there a way to display in the legend of a map the total survey length instead of the total maps length? I have a survey where the total cave length shown in the plan legend is smaller than the total length displayed in the statistics (the statistics file is correct and there are no duplicate surveys). I cannot understand where the discrepancy might come from, but I suspect it is related to the maps (I have some surveys that do not appear on the plan and for which there is no .th2 files). Thanks, Martin

xTherion will not open JPG backgrounds
by Bill Gee 28 Jan '26

28 Jan '26

Dang it ... I remember seeing this problem some months ago, probably in June, but now cannot remember how I fixed it. Therion 6.3.4+dev running on Fedora 43. In late December I worked on a cave map and had no problems with it. xTherion opened jpg files as backgrounds. Today I went back to that same map, and it will not load the background jpg files. It will open png backgrounds. The only error I can see is in the Background Images field. It shows the name of the jpg file and adds "(unknown)" at the end. I checked both tkimg and libjpeg. They are installed. What else is required for this to work? I started xtherion from a command shell. There were no additional error messages. Is there a log file somewhere that might give more clues? In early January I ran the usual update process for all packages. Both tkimg and libjpeg were updated. I don't see anything that was removed other than old kernels. Thanks! -- =============== Bill Gee
