I wrote an alternative fonction to open AutoCAD drawings. However, AutoCAD made it really hard to change how a document is opened when it is ran from Windows Explorer (double click the file with file association). The only method I found is to change a registry key which is "OpenDdeExec". There is a supplied argument (%1) that gives me a unescaped path to the file to open.
I need to ignore the escaping in path or replace the backslashes with double backslashes before it gets parsed as being special characters. In C#, you could do something like string s = @"I\Like random\backslashes";
and backslashes would be taken as the actualy backslashe character. In lisp, the only equivalence I found is quote
which has a weird behavior (since it's normal use isn't exactly what I'm trying to acheive).
If I write something like (quote (I\Like random\backslashes))
, the outcome will be (I\\Like random\\backslashes)
which is ALMOST what I need. However, I have to get rid of the parenthesis. Any idea how I can acheive this?
Note: Doing this (quote I\Like random\backslashes)
will break due to the space. It would, however, work on (quote I\Like\backslashes)
. This would output I\\Like\\backslashes
just like I want.
This is the current OpenDdeExec with the described issue:
(OPENFROMSHELL (QUOTE (%1)))
This is unfortunately not possible with AutoCAD's limited LISP.
