where is/name of the match properties .lsp file ?

[yairMSKTU]

i want to learn / make my own lisps based on existing ones i use alot.

where can i find the match properties .lsp ?

is there a website with the default commands files list, to make it easier for users to find ?

If you follow up on your question from last week, THIS routine could solve your issue or at least help to solve it.

Lee's website is worth exploring, one of the best public libraries we have. But... for learning, in general, is probably better to start HERE. Lee's programs might be too advanced to learn from.

Also, the good resource with many examples, I think even with a tutorial, is HELP 

Lastly, just to be clear. The built-in commands as MATCHPROP are not distributed as *.lsp files. They are not adjustable. You can use them in your LISP routines just as a black box. Contrarily some of Express Tools ARE LISPs, see in help where the files are stored. But still, see their copyrights.

i have some history with basic java and c+ and scripts so i can understand these basics.

the idea is to create a sort of match properties with settings of "text", but add to it a specific custom text style, which is not the same from the source text.

so the idea is to take the match properties lisp and add to it a few lines for that plot style. 

im almost done with my work,  but im sure something like that would help me in the future.

I have thought about that myself because not every property gets matched.

So I think you have to build a list of all the properties that can be, eg.

(setq littany '(height width textstring layer color etc. etc.))

and then

(foreach property littany
  (if 
    (and
      (vlax-property-available-p source property)
      (vlax-property-available-p target property)
    )
    (vlax-put target 'property (vlax-get source 'property))
  )
)

Looks simple, right?  BUT in many cases the property of one object type may not be named the same as the same property of another object type.  AND you can't put areas and lengths,  AND you shouldn't put textstrings, or insertion points, or coordinates, or northings and eastings, and elevations.  AND probably thousands of other caveats that leave my mind boggled.

But what the heck; give it a shot.  Best of luck.

This is something I worked on as Library function get what you want from an object. Look at bottom for examples.

Nice, Alan. Well organized.
Too bad I was impatient and copied your code from my e-mail, thereby having
to add all the indentation.
Anyway, I think you need to change...
(defun arcprops (obj txtlst)
to
(defun arcprops (obj lst)

[Sea-Haven]

Thanks will fix, if I could edit post would fix here also silly 30 minute timer.

[john.uhden]

Well, if it takes you that long until you realize an error, then ...
.
Hey, that's why the rest of us are here... to notice little mistakes,
that's all.
Meanwhile, why didn't you notice that I went out with the wrong car
keys this morning? 🤔

[ВeekeeCZ]

Well, let me advise you, actually you can edit your posts as much as you want. Times has changed.
