does keyword expansion work?

[Christopher Chen-2]

Hi,

I'm using CSSC-1.2.0.  The keyword expansion feature (ex. %W%) does
not seem to be working.  Does it work?

Thx.

Chris C.

It works in BitKeeper just fine :)  Not that that helps you much, but
at least you know there is a (commercial) option that works...

We support many of the RCS keywords too, but not $Log$, I always thought
that was a bit over the top.  Here's our list if you care.

--lm

bk keywords(2009-08-20)     BitKeeper User's Manual    bk keywords(2009-08-20)

NAME
       bk keywords - list of RCS and SCCS keywords

DESCRIPTION
       BitKeeper  supports both the standard SCCS keywords, as well as most of
       the RCS keywords. In addition, there  are  several  keywords  that  are
       unique to BitKeeper.

       Note:  All  of the revision-oriented keywords (e.g. %I%) are useless in
       BitKeeper since they may change as a  result  of  a  re-synchronization
       that  causes  a  branch creation.  Use the %K% keyword when you need an
       identifier that is unique to a specific revision-level of a  file.  The
       %K% keyword is useful when tracking customer bugs. For example, a tech-
       nician might ask the end-user to run the what command on an  executable
       to  check  the  versions of the components that make up a program.  The
       person doing troubleshooting can then use the %K% keyword to track down
       the specific source files that make up the executable.

       Note: SCCS keyword expansion can cause problems in printf-like strings.
       To deal with unwanted keyword expansion, BitKeeper can be given options
       to expand only the first keyword found. See bk help admin.

SCCS KEYWORDS
            %A%  Shorthand notation for an ID line with data for what(1):

            %U%  Time the newest applied delta was created: hh:mm:ss    12:41:29
            %W%  Shorthand notation for an ID line with data for what:
                 %Z%%M% %I%     @(#)GET                  1.1

            %Z%  4-character string: recognized by what. @(#)

It does:

$ rm -f s.foo foo; echo "Hello.   %W%." > foo ; ./admin -i s.foo < foo
; ./get -p s.foo  2>/dev/null; rm -f s.foo foo
Hello.   @(#)foo        1.1.
$ rm -f s.foo foo; echo "Hello.   %W%." > foo ; ./admin -i s.foo < foo
; ./get -wBLAH -p s.foo  2>/dev/null; rm -f s.foo foo
Hello.   BLAH.

Alright, I'll have to chalk it up as some sort of
operator error somewhere--since I did not keep a log to show.

It worked just fine this morning.  Sorry for the alarm.
Thanks for the help.
