Compilation outcome depends on order of source statements
by Bruce Mutton 05 Feb '24

05 Feb '24

Here is an issue that took me too many days to unravel. The order of source statements in a thconfig affects the outcome of the compilation. I think the problem, or constraint, can be described as: * Multi-line source statements must follow all single line source statements, else not all surveys will not be read correctly, or * Single-line source statements that follow a multi-line source statement will not be read. For example, a thconfig contains: source ./Greenlinkcave/INDEXGreenlink.th source ./swissmaidcave/INDEXSwissMaid.th source #join the two cave surveys without an index file equate 133(a)jp.SwissM I68(a)s.Greenlink equate 156(a)second.SwissM S45(a)ss.Greenlink equate 144(a)jp.SwissM H32(a)h.Greenlink endsource source ./middleearthcave/INDEXMiddleEarth.th source #join the two cave surveys without an index file equate F76(a)f.MiddleEarth F102(a)f2.Greenlink endsource This results in a fatal error: reading source files ... done preprocessing database ... done C:\Program Files\Therion\therion.exe: error -- ./middleearthcave/INDEXMiddleEarth.th [24] -- survey does not exist -- 74 Which confused me because each of these would compile alone an in combination via other thconfig files. If I changed the order of the source statements, the 'non-existent' survey would change. I tried 6.2.0 + fd5c1b6 and 6.17 and 6.13 all with similar effect (although I'm not that confident because the latter two being 32-bit and toggling between the 64-bit 6.2.0 variants results in duplicate therion programs on my Windows machine, thus I'm not sure I have 'clean' installs). Too late, I tried putting all the single line sources first, followed by the multi-line sources, and viola, success. So this seems like a bug, in that I understand Therion should read all sources before processing the survey and map input. With sources, this seems not to be happening, and Therion is crashing inappropriately if the sources are not listed in the 'correct' order. Bruce PS: Yes, I know the example above is a rather messy way of treating sources. I would not usually do this - it is a hack to work around an unfortunate decision made early in the project history.

XVI commands: xth_me_area_adjust etc.
by Rich Smith 03 Feb '24

03 Feb '24

Hi Therion I'm the author of cave surveying app SexyTopo, and I'm trying to write a better Therion exporter. Previously I'd kind of hacked an exporter that did an approximate job, but I'm rewriting it and trying to do a better job. I understand I should generate an XVI file for each projection that represents the sketch. I then need to set this in the th2 file with some commands. For example: ##XTHERION## xth_me_area_adjust -132.0 -156.10532659555793 1768.2371519518056 726.0 ##XTHERION## xth_me_area_zoom_to 100 ##XTHERION## xth_me_image_insert {950.6824683592552 1 1.0} {267.841199967364 5} {blaengwynlais plan.xvi} 0 {} Are these documented anywhere? It seems like xth_me_area_adjust sets the dimensions of the image, and xth_me_image_insert specifies the position and filename, but I'm not clear what all the values represent. Many thanks for any pointers! Rich

station-names []@survey not implemented for point station -from option
by Bruce Mutton 02 Feb '24

02 Feb '24

Kia ora Maybe I found a minor bug. I have an extended elevation that includes a loop (many actually) and of course there is a gap in the loop as rendered that I would like to illustrate with a map-connection line. Where the yellow shading is in the image below, I would like to draw a horizontal map-connection line. So following the guidance in the Therion Book pages 105 and 106 I have created a scrap. scrap 2-HawkesElevEXT-s1connection -projection extended -station-names []@2 point 0 0 station -name 2.4 -from 2.5 point 100 0 station -name 2.4 -from 2.3 line map-connection 0 0 100 0 endline endscrap On creating the scrap and before referencing it in any maps, Therion is unhappy and exits with the following: #################### end of cavern log file #################### done calculating basic statistics ... done processing extended elevation ... done processing references ... C:\Program Files\Therion\therion.exe: error -- string pointer is null writing xtherion file ... done Am using therion 6.2.0+fd5c1b6 (2024-01-10) On experimenting a little, I realised that -station-names has no effect on the -from station parameter. So this was my workaround. scrap 2-HawkesElevEXT-s1connection -projection extended -station-names []@2 point 0 0 station -name 2.4 -from 2.5@2 point 100 0 station -name 2.4 -from 2.3@2 line map-connection 0 0 100 0 endline endscrap I'll create an issue in GitHub.

Subtypes can't have numbers?
by Rodrigo Severo 14 Jan '24

14 Jan '24

Hi, Just trying to set a "line u:s41p" symbol on latest Therion and getting strange metapost errors: ! Missing `=' has been inserted. <to be read again> 51 l.6846 let l_u_s51 p = l_u; You should have said `let symbol = something'. But don't worry; I'll pretend that an equals sign was present. The next token I read will be `something'. ! Missing symbolic token inserted. <inserted text> INACCESSIBLE l.6846 let l_u_s51 p = l_u; Sorry: You can't redefine a number, string, or expr. I've inserted an inaccessible symbol so that your definition will be completed without mixing me up too badly. ! Extra tokens will be flushed. <to be read again> p l.6846 let l_u_s51p = l_u; I've just read as much of that statement as I could fathom, so a semicolon should have been next. It's very puzzling... but I'll try to get myself back together, by ignoring everything up to the next `;'. Please insert a semicolon now in front of anything that you don't want me to delete. (See Chapter 27 of The METAFONTbook for an example.) ! Missing `=' has been inserted. <to be read again> 51 l.6847 def l_u_s51 p_legend = l_u_s51p(((-.3,0.5) .. (.3,.3) .. (.7,.7) .. (1... The next thing in this `def' should have been `=', because I've already looked at the definition heading. But don't worry; I'll pretend that an equals sign was present. Everything from here to `enddef' will be the replacement text of this macro. I believe that subtypes aren´t supporting all chars allowed by <keyword> as defined in THBook page 13 (Data types). Is it a bug or am I misreading something? Regards, Rodrigo

Flush logfile output (PR #541) - Therion log file truncated prematurely
by Bruce Mutton 11 Jan '24

11 Jan '24

Thanks Matěj Limited checking suggests therion.log files created with this commit are complete up to the ### end of loop errors ###, although I am expecting scrap distortions and CRS transformations, and there are none. Not sure if this is my oversight or something that should be written and is genuinely missing.

Semi-transparent rock borders
by Rodrigo Severo 10 Jan '24

10 Jan '24

Hi, I have some closed rock borders that are opaque as expected when viewing my PDF file in Adobe Acrobat and FoxIT but are semi-transparent in Okular and Atril. Any suggestions on how to make them really opaque (on all PDF viewers)? Regards, Rodrigo Severo

Change altitude colours
by Paul Rowe 01 Jan '24

When using: *colour map-fg altitude* ... is it possible to change the default colours used? I could see notes about setting this scrap by scrap, but not for the automatic graduation of altitude colours. Thanks Paul Rowe

New package needed - Therion 6.2.0 on Fedora 39
by Bill Gee 21 Dec '23

21 Dec '23

I jumped on this quick! :-) And ran into a problem. This happens when running cmake. The solution was to install catch2-devel using DNF. Note that there is also a package called "catch22-devel" which I did not install. After installing catch2-devel, the compile and install proceeded with no problems. =============== -- Checking for module 'proj' -- Found proj, version 9.2.1 CMake Error at cmake/Catch2.cmake:17 (find_package): By not providing "FindCatch2.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Catch2", but CMake did not find one. Could not find a package configuration file provided by "Catch2" with any of the following names: Catch2Config.cmake catch2-config.cmake Add the installation prefix of "Catch2" to CMAKE_PREFIX_PATH or set "Catch2_DIR" to a directory containing one of the above files. If "Catch2" provides a separate development package or SDK, be sure it has been installed.
