There is the problem that passage-height is hard coded, not defined in Metapost. Martin S. Odesláno z iPhonu 20. 9. 2018 v 21:38, Bruce Mutton via Therion <therion@speleo.sk>:
One of the developers added a NZSS symbol set some years ago, based on a few symbol definitions I posted on this forum. I have some more symbol definitions I would like to add to it, btw. If someone points me to the general code location, I might try to cut my teeth on git and add those extra definitions.
A new symbol set can include as little as a single symbol, so it should not be a big job Bill. You can simply reassign symbols from other symbol sets for those not defined in your chosen symbol set. ie
symbol-assign line gradient UIS symbol-assign point gradient UIS
Maybe some learning we can do together Bill (on adding to symbol sets).
Also for what it is worth, I made this clumsy attempt at text within boxes (or sorts). Not quite what you are after, but might give some ideas.
A more generally useful thing I have been wondering about for point labels and point remarks (or line labels for that matter) would be the ability to add a box around the text, as a simple property of that entity, activated in the same way as we specify -align left or -scale xs. And even a -hyperlink [path|url] would be useful

Hi Martin -
Now that is an interesting idea! Most of the symbols used in Missouri are UIS, so that would serve as the starting point.
Is there any documentation on how to create an entire symbol set?
And my original question is still there ... How can I create a symbol that puts a number inside a square box?

The correct way could be to define “Missoury symbol set” as one of defaults for Therion.
It should be more simple than user symbol, because it will work with contents menus.

Hi Andrew -
I have defined several of my own symbols such as a pendant and popcorn with hollow circles. I could easily define a custom point that would display a square box.
But then how to get the value displayed inside the box? And how to make the box scale according to the number of digits it contains? And will Therion do unit conversions like it does for the passage-height object? That's why I was looking for the existing code. If I can find it, then it is probably pretty easy to modify.
Yes that is probably possible, however, using a defined symbol for something else is probably not the right answer. Therion allows you to define your own points.
From the wiki
point u:xxxx where xxxx is the name of a user defined symbol that you have defined or referenced in a layout.
The actual definition seems to be beyond me at the moment, let me sleep on it, but hopefully a more skillful person will have the answer.

A common convention around Missouri cave mapping is to indicate the height change of a floor step by enclosing the value in a square box. This is not the same as ceiling height which is enclosed in a circle or oval.
I have been using the object "point height" for this. It works except there is nothing around the value. It just hangs out in space, so to speak.
I used the "-d" option to dump all the MetaPost and TeX code. I find no references in any of the files to objects of type height or passage-height, which implies that these two objects are not generated by MetaPost.
Is it possible to redefine the "point height" symbol so it draws a square box around the value?
Thanks! -- Bill Gee
