Hello, unfortunately this does not help. The standard "?"-symbol does show like expected.
It is just the extension code not having the stated effect if showing the text. As such, i just want to override the default p_continuation symbol with the code showing the text, and only so when i choose it by including the layout option.
It just looks like the "if" clause in the code is not run properly, however it is correctly included in the parse because i can break the compile process when introducing garbage code there.

Hi Benedikt, Adding a continuation ? should be a standard use of a TH2 file, check in: points/All Symbols/Possible continuation/Type [continuation]. This should produce a ?, even without the code to produce the text as well. If it's not producing a ? then there's something going wrong before. I've never tried adding continuation text, but I assume you're adding the text to the options box (much like producing a label). Options: -text "water too cold to continue" -code A If you're not adding this to the options then this is what is causing your problems. If it doesn't solve your problems, then we were having fun defining new rocks and Debris a couple of months ago. To insert these new icons, there were a few steps to go through. The test example is on Wookey's website, so I can't take credit for that, but it does just reduce the problem of defining new symbols to a simple file, so is a good example for you to look at and work out. http://wookware.org/surveys/therion/index.html In the Config file Wookey and Andrew defined the symbol in the layout. "Symbol-assign area debris TEST" Then Initiated the Symbol within the Metapost wrapping "initsymbol ("a_debris_TEST") and then defined the symbol. At present I think you may have only defined the symbol. So i'd advise also trying to define your continuation as def p_continuation_TEST(expr pos,theta,sc,al) = Then above assigning the symbol symbol-assign point continuation TEST and then within your metapost wrapper initsymbol ("p_continuation_TEST") By doing this, you should be able to turn on and off your "test" point continuation by # the symbol-assign line. as Wookey and Andrew did below for the AUT and SKBB blocks.

Hi, i try to add a layout for showing the question mark texts. For this i tried the additions from the websites: a) https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftherion.speleo.sk%2Fsamples.doc%2F60.html&data=02%7C01%7C%7C0ca209370ddc495c109308d667ffbce5%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636810745412347133&sdata=WEN25vHGKS75bd2iOmYY8N3phCECVrGVoznqMnrqC20%3D&reserved=0 [1] b) https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmarcocorvi.altervista.org%2Fcaving%2Ftbe%2Fm_05%2Fm_054.htm&data=02%7C01%7C%7C0ca209370ddc495c109308d667ffbce5%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636810745412347133&sdata=3FtoNdR%2BuWBMfXX3hZtoNaKunH9%2FrMfyeyyrE5TXdzw%3D&reserved=0 [2] but neither seems to work. a) produces no change and b) triggers a compile error :( This is a) implemented in my layout.conf (taken from the web) --------------------------- layout showContinationText.inc code metapost def p_continuation(expr pos,theta,sc,al) = % draw question mark above station: % rotation=0, scaling=1, offset=(0,2) % p_continuation_UIS(pos, 0.0, 1.0, (0, 2) ); % if text attribute is set if known ATTR_text: % set labeling color to red push_label_fill_color(1.0, 0.0, 0.0); % draw filled label with text below station p_label.bot(ATTR__text, pos shifted (0,-0.5u), 0.0, 8); % restore original labeling color pop_label_fill_color; fi; enddef; endcode endlayout -------------------- and my thconfig export command includes this: "-layout showContinationText.inc", which in other cases is enough to activate it. The layout file is also loaded, i checked that. However, no text is shown... What am i doing wrong?
