Upper case in path to file in digital source

[George]

Hello!
I faced with issue: if I have upper case in path to file in XSPICE digital source, ngspice doesn't read the
the file, for example: /home/george/MDPSBLib/combinational_logic_test.txt
and I got the message:

Instance: a.x34.a1   Message: cannot open file /home/george/mdpsblib/combinational_logic_test.txt

Instance: a.x34.a1   Message: 
ERROR **
 D_SOURCE: source.in file was not read successfully. 

If I place file in /home/george, it reads great. I think the issue is in upper case, because in error message it make all case lower.
Thank you in advance!

cd /home/george
ln -s ./MDPSBLib mdpsblib

Yes, but it is a workaround that sometimes is not plausible to use...so this behaviour could be considered as a bug, no?

l agree that it is a bug, similar to the logged #290 and #424. As more syntax was added the forcing of consistent case and stripping of quotes and white space became too aggressive. My guess is that it should be moved to the sub-parsers for different device lines, where there is more context. But a fix would be long and complex, with little reward for the developer and a very high potential for new, subtler bugs.

Please see commit https://sourceforge.net/p/ngspice/ngspice/ci/89d35fb34b7d49187037edeb8d99f9fb4aa23be7/

So try compiling ngspice-42+ from pre-master-43 git branch or (if you are using MS Windows) https://ngspice.sourceforge.io/experimental/ngspice-42plus-pre-master-43.7z
