Hello All, while investigating my build-problems with r21-2b4 I started playing and found it not to support relational expressions. So I implementad that and it seems to work fine. However, the handling of numbers is rather peculiar. I would like to hear some feedback from authors or experienced users of hide-ifdef-mode, whether this works as it should, or what improvements would be welcomed. Where would I send my patches? Maintainer says FSF. Is there no owner for this in XEmacs? For each number occuring in an #if expression an interned symbol is created and looked up in the assoc list hide-ifdef-env to decide whether to hide that block. So, #if 0 /* Testing decimal number */ #endif #if 1 /* Testing decimal number */ #endif will be displayed as follows after M-x hide-ifdefs #if 0 ... #endif #if 1 ... #endif because the (intern "0") and (intern "1") are not found in hide-ifdef-env To display the #if 0 bit, one would M-x hide-ifdef-define RET 0 RET Hmmh, I'll have to think about this some more.
