I can't think of a case (outside of "0x...." context) where "...0b..." would be valid C code, let alone better formated as "...0 b...". Hence I see no harm in adding your patch to the base indent(1). Does anyone have an example where "...0 b..." is valid C code? > A quick look at indent(1) source code leaded me to tweak > /usr/src/usr.bin/indent/lexi.c so that the 0b notation is supported > (patch attached). > > I was so wondering how useful(less) it was to support this extension in > FreeBSD indent(1) program.
