I'm getting some screwy indentation behavior from C mode. From a
current bzr checkout/install of emacs, try the following recipe:
emacs -Q foo.c | starts emacs on foo.c (included below)
C-u 7 C-n | move down 7 lines
TAB | indent, nothing changes (good)
C-p C-p | move up 2 lines
TAB C-n TAB C-n | indent 2 lines, nothing changes (good)
TAB | line unindents by 2 (bad)
TAB | line re-indents (good, but strange)
TAB | no change this time
And here's another recipe for weirdness:
emacs -Q foo.c | starts emacs on foo.c (included below)
C-x h | select buffer
C-M-\ | indent region everything from line 7
| down to the while (0) unindents 2
C-u 5 C-n | move down to the do {
C-x ( TAB C-n C-x ) | define a macro to indent and move down
| a line
C-x e e e e e e | Indent each line, no change
Here's foo.c
#if !SK_ENABLE_IPV6
# define skipaddrApplyCIDR(ipaddr, cidr) \
ipUnionApplyCIDRV4(&(ipaddr)->ip_ip, cidr)
#else
# define skipaddrApplyCIDR(ipaddr, cidr) \
do { \
if (skipaddrIsV6(ipaddr)) { \
ipUnionApplyCIDRV6(&((ipaddr)->ip_ip), cidr); \
} else { \
ipUnionApplyCIDRV4(&((ipaddr)->ip_ip), cidr); \
} \
} while (0)
#endif
