FAS Project File location

Phillip Rutledge

Hi there,
I am attempting to recreate a DES file using the DECencoder program without having to re-enter every (80+) file names in the PRV file. The LISP files listed in the PRV have been relocated. I did a search and replace in the PRV file with a text editor but I still get the following message.

This message says the program doesn't recognize the changes I made in the file.
Am I making any sense here?

Thank you in advance for your help.

Dear Philipp,

have you tried latest DEScoder.exe v2.7, as installed with V18.2 ?
As I recall, there was a problem with relative pathes for Lisp file notation, in DEScoder v2.6.

You might also attach your prv/prj file(s) here (or in a SupportRequest), so I could have a look at it.
many greetings !

Thank you very for your help Torsten. I missed the v2.7 version installed with V18.2.
The issue has been resolved.

Have an enjoyable Easter weekend.

Dear Phillip,

glad to hear that it works for you now
As v2.7 offers "VLX NameSpace" support, please be aware that such DES containers created with NameSpace=ON will not work properly in V17 and older - as there was no such built-in support at Lisp engine level.

Except that detail, all others remain compatible.
many greetings !

Hmmm, forgive my ignorance but I am trying to understand the purpose andl/or practical application.
If you are able to enlighten me without too much time or trouble I would greatly appreciate your help.

Thanks for everything Torsten.

Dear Philip,

but I am trying to understand the purpose and/or practical application.

you mean that "VLX NameSpace" feature ?
If you never used that before with AutoCAD/AutoLISP, then you can entirely ignore that option (and leave it OFF)

In AutoLISP, you can create VLX "container" files (Lisp,Dcl,Tx combined into 1 single "container" file) - and additionally, request that all the Lisp code from such VLX uses its own "name space" - which is effectively having all symbols (functions, values etc.) to be bound to the scope of that VLX file;
which means, it isolates all data from other Lisp files & routines.

But as nice as such feature is to prevent collisions & clashes of same-named Lisp symbols - it requires a special preparation of that Lisp code, to access "outside" symbols, and to export own symbols to the "outside world" (using import + export statements).

hope this can put a bit light on the topic ...
many greetings

Thank you Torsten,
If memory serves me correctly the AutoCAD Lisp editor would create a VLX (container) file. Yes, I used it back then but now use DESCoder to create my "container".
Based on your advice I will continue to use DESCoder. (if it's not broken, don't fix it).
Thank you for taking the time to reply.

Dear Phillip,

that VLIDE can create both FAS and VLX target files - but only VLX format additionally allows to use "NameSpace" ...
with DEScoder.exe, the "NameSpace" feature can be used for both "single-file DES" (like FAS) and "container-file DES" (like VLX);
but as mentioned, any developer using that "NameSpace" feature should be really aware of what it does & what it requires in Lisp sources - on both AutoCAD and BricsCAD

many greetings !
