( #3333=superdoc: print w/replies, xml ) Need Help??
I want a rexex s///e to bump up the build number, eg. from 0.8.34.0 to 0.8.35.0. I tried the following, but was stalled in the regex...

#!/usr/bin/perl -w use strict; my $version = '0.8.34.0'; # This works as expected $version =~ /(\d+\.\d+\.)(\d+)(\.\d+)/; $version = $1 . ($2 + 1) . $3; print "$version\n"; # but this won't compile, --- why? #$version =~ s/(\d+\.\d+\.)(\d+)(\.\d+)/{$1}$2+1{$3}/e; print $version;

Update
Ok OK!! Folks, flowering TMTOWTDItis .. :-D Thanks! -- allan
#!/usr/bin/perl -w use strict; my $version = '0.8.34.0'; $version =~ /(\d+\.\d+\.)(\d+)(\.\d+)/; $version = $1 . ($2 + 1) . $3; print "$version\n"; $version =~ s/(\d+\.\d+\.)(\d+)(\.\d+)/$1.($2+1).$3/e; print "$version\n"; $version = do { my $v = [ split /\./, $version ]; $v->[2]++; join '.', + @$v }; print "$version\n"; $version =~ s/(\d+)(?=\.\d+\z)/$1 + 1/e; print "$version\n";

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
