| Description: |
The attached patch adds a %b specifier meaning 'binary' to the [format] and [scan] commands. It is thus continuing in the direction pioneered by the recent addition of "0b" in [expr]'s number parsing. The specifier of course also works with "#" (adding "0b" if nonzero) and wide- and bignum modifiers (%lb, %llb). In addition, the patch fixes the following bug in [scan]: % scan 0b101 %i x 1 % puts $x 0 The patch includes proper tests and documentation update. Does it really need a TIP ? | |||

TIP accepted, patch committed. ferrieux added on 2008-12-09 04:21:45: The mention of "octal" in the previous comment is confusing. I meant, let's just leave %i in all its historical ugliness (which includes things related to octal). Anyway. ferrieux added on 2008-12-09 04:19:36: After discussion with Don, it appears that the [scan %i] "fix", which is orthogonal to the TIP, is a dangerous breach of compatibility. So let's leave octal in its pond for now. Patch updated to restore the aforementioned bug. Now this patch is 100% faithful to the TIP's text.
