Question

Hi.

I would like my WebLeftBar to contain a list of anchors derived from the headings in another topic - i.e. the %TOC% of another topic. I've tried adding the following to my WebLeftBar :

%TOC{"MyContents"}%

This works perfectly when I view all topics except the MyContents topic - I get a nice list of all the headings, which link to the correct place. However, when I view the MyContents topic, I get the following message in the WebLeftBar : "TOC: No TOC in "GNBWeb.ByTools"" - even though the there is a TOC gnereated in the main page - it just doesn't exist in the WebLeftBar.

I guess the PatternSkin is interfering with the TOC generation in some way - does anyone have any clues how to work around this ?

Cheers,

Steve.

Thanks for the pointer. Your patch won't fit with Cairo, which seems to have the following in TWiki.pm :

   my $result  = "";
    my $line  = "";
    my $level = "";
    my @list  = ();
     
    if( "$web.$topicname" eq "$_[2].$_[1]" ) {
        # use text from parameter
        @list = split( /\n/, $_[0] );

    } else {
        # read text from file
        if ( ! &TWiki::Store::topicExists( $web, $topicname ) ) {  
            return showError( "TOC: Cannot find topic \"$web.$topicname\"" );
        }
        my $t = TWiki::Store::readWebTopic( $web, $topicname );
        $t =~ s/.*?%STARTINCLUDE%//s;
        $t =~ s/%STOPINCLUDE%.*//s;
        @list = split( /\n/, handleCommonTags( $t, $topicname, $web ) );
    }

I am comforatble with PERL, but nervous about modifying TWiki.pm on a busy, live intranet.

Can anyone suggest a way to patch this for Cairo ?

Quick note on updating a live system:

• Install two TWiki engines on the same server, call it Beta and Prod (for production)
• Configure Apache to access both engines with different base URL for cgi-bin
• Configure Beta TWiki to point to Prod for data and pub
• Keep Beta and Prod engine in sync
• When you want to install a new Plugin or make a small change to the engine do that in Beta
• Once tested (functionality, bugs, performance) you can sync the changed files into production. You can do that on the fly, users don't realize the change.
