timestamp and possible svn version number in
my application during the build process. What's the best way of
doing this?
The way that I do it is use a custom build tool target upon which my
main target depends (build phases don't work, or didn't work when I
made this <rdar://problem/4068837>) which runs the simple perl script:
#!/usr/bin/perl -w
use File::Copy;
$ver = 0;
if( open FH, '<ver.cpp' )
{
<FH> =~ /version_num = (\d+);/ and $ver = $1 + 1;
close FH;
}
chop( $date = `date` );
open FH, '>.ver.tmp' or die $!;
print FH <<"EOF";
extern const unsigned long version_num = $ver;
extern const char *const version_time = "$date";
EOF
close FH;
move '.ver.tmp', 'ver.cpp';
It opens up ver.cpp if it exists and grabs the version number (which
is really just a build number) and increments it and then writes the
date/time and build number back to the file.
