Efficient way to crop text by length in cm

Anonymous — Tue, 14 Sep 2021 07:48:28 GMT

Hi,

i hope I haven’t missed a function, but I’m looking for a efficient way to crop text by a given length and not by the number of characters, like “strsub”.

Maybe somebody have a better solution.
My actual solution is:

while stw(txt1) >100 do !** 100 is the max lenght of the text
txt1=strsub(txt1,0,_loop)
_loop=_loop-1
endwhile

With Richtext2 this should work.
Drag and drop a multine 2D Text into a 2D Script window
and define Parameters for Text content and text length and replace the
hard coded values by the parameters in the script.

Hi Joachim,

i think with Richtext2 i only have the option to get a linebreak after the given lenght, so that i get a new line when the text didn't fit, what i want to avoid.

So just to be clear.
You don't want the text to wrap to a new line.
You just want to cut the text off at a certain width and not after a certain number of characters?

Yes exactly

Not really sure why that would be useful, but it's certainly an edge case. There is no built-in function for that.

What you've done there is already quite good.
The only way there might be to improve the execution time, would be some kind of "divide & conquer" algorithm.

You're right, an edge case, that's why i haven't asked some years ago.

F.E. when you have an object, which shows the change history of an layout, like the Graphisoft Object already does. The content of the name is limited to 255 char., when you want to limit the column width you have to use linebreaks, which may cause to many lines.

Okay, this might be an legitimate example, which I can totally understand.
Still an edge case, tho.

Also: Would you really want to split a word at an arbitrary position?
This will look weird to anybody who reads it, for sure.
I guess you're the BIM manager of your office (or a similar position). Maybe you can introduce a special char as a delimiter (like ";") in your office. And everything after that char gets cut off.
Or you just split by space (" "). This might be the easiest and best looking solution. It will also perform slightly faster than looping through every character, I assume.
Maybe even leave enough room for an ellipsis ("…") to append to the string, so it doesn't look as bad.

The idea was, to have it as option. Maybe sometimes it's better to crop one name of a change, than to push others out of the table. You're idea with the ellipsis is nice.

I've started in investigate, if a simplified object for the change management makes sense.

I'm no a BIM Manager, i'm ArchiCAD Trainer, Consultat, Instructor at Graphisoft Berlin.
Maybe i should revise my signature

Ah, like... for distribution in the D(ACH) space with the next release?

No, I'm not in Graphisoft Product Management. I'm not responsible for the library.
