Hi folks, A question relating to TEX. Previously, I used to use this: thTEX("\thframed {" & textsize & plaintext & "}") Where textsize was something like \thnormalsize This worked until recently. But now (Therion 6?) it returns nothing. After some trial and error (and looking through the -d output), I managed to make it work again like this: thTEX("\thframed {" & textsize & " \thfb " & plaintext & "}") But I have no idea why that works, and was hoping someone could explain to me: 1. What is \thfb ? 2. Why does it need that, and not a space? 3. How come it works without the whitespace, when plaintext could be anything, and that could construct a btex like: \thframed {\thnormalsize\thfbfoo} I would have expected \thfbfoo to be a command, but it seems to know that it is "\thfb" and "foo", not a single command. 4. Is there a better way to construct a btex "string" that can be used to create a p_label.urt piece of text that can work with the p_label_mode_passageheight style? For reference, this is what Therion itself creates: p_label(btex \thframed {\thsmallsize \thfb\char54 \mainfont{}} etex,(16.93,13.78),0.0,p_label_mode_passageheight); Stabbing in the dark here, and cannot find any explanations.
