(as a demo) outputs '4085' on my current checkout. Designed to handle the case where you have one or more commits that haven't yet been committed to SVN, only locally, as well as the case where you don't. The idea, if you don't speak grep-ese, is simply to find the log entries with 'git-svn-id' on some line, take the first one, and extract the bit of text following 'ohrrpgce/SVNBRANCHNAME@' (stopping at the next space) Writing a little FB program to do that would probably be the most portable solution. .. it's been ages since I actually wrote any BASIC. pseudo-ish code follows: ' ** get the output of "git log --grep=git-svn-id" (could be done in advance by the build system) ** ' ** read lines until INSTR (thisline, "git-svn-id") > 0 ** ' and now find the part of the line we want svnspecstart = INSTR (thisline, "svn://") svnspecnumstart = INSTR (thisline, '@', svnspecstart) + 1 svnspecnumend = INSTR (thisline, ' ', svnspecnumstart) version = MID (thisline, svnspecnumstart, svnspecnumend - svnspecnumstart) PRINT version _______________________________________________ Ohrrpgce mailing list ohrrpgce@lists.motherhamster.org http://lists.motherhamster.org/listinfo.cgi/ohrrpgce-motherhamster.org
