GDL: User Input - "Can't Find Macro" - Return

Lingwisyer — Wed, 26 Apr 2023 02:09:04 GMT

Hi all,

I have a macro call in which the user can inser their own symbol objects, and I was wondering if there was a way to detect whether the inserted name exists so that I can ignore the input if it does not whilst giving a notice about it. At the moment it just fails to generate which is highly inconvenient.

Could you use OPEN to test for the file presence and use the return values followed by CLOSE?

folder = OPEN (called_object, "c:", "FILES")

Any idea how you would point that at the loaded libraries?

Hm. Found Runxel's thread about this...

Figured out how to use the text I/O to query if the file exists

channel = OPEN ("TEXT", marker_call, "library") IF marker_call # "" & channel # -1 then !Name inserted, name exists (actually > -1) MUL2 marker_height * (-10) * GLOB_SCALE, marker_height * 10 * GLOB_SCALE CALL marker_call parameters ALL, penAttribute_1 = penAttribute_1, penAttribute_2 = penAttribute_2, penAttribute_3 = penAttribute_3, penAttribute_4 = penAttribute_4, fillAttribute_1 = fillAttribute_1, fillAttribute_2 = fillAttribute_2, lineTypeAttribute_1 = lineTypeAttribute_1, lineTypeAttribute_2 = lineTypeAttribute_2 DEL 1 TEXT2 0, 0, channel else IF i = 1 then TEXT2 0, 0, "Marker Name Not Found" endIF endIF

Hm. The OPEN command does post around 80 lines to the Session Report saying that the file is not found which is a bit excessive...
