Question

I am trying to use %WEBLIST% to generate text for all (visible) webs on my TWiki. I'm finding that there are two problems:

1. The "\n" as newline metacharacter doesn't work in the format or seperator line.
2. Any % characters within a format or other option cause %WEBLIST% to break.

Sample of what I'm trying to do -- generate a stats page with global statistics for all webs. Though this works, the headers (---++) don't resolve properly because they don't align with a newline:

%<nop>WEBLIST{ format="%INCLUDE{'$name.WebStatistics'}%"   }%

What I see:

Admin Design Know Main Plugins Portals Sales Sandbox TWiki Tech Test" }%

What I expect to see is (repeated for each web):

%INCLUDE{"Support.WebStatistics"}%

• TWiki version: 01 Dec 2001
• Web server: Apache
• Server OS: RH Linux 7.2
• Web browser: Galeon 1.x
• Client OS: Debian GNU/Linux (Woody)

Answer

The separator attribute in %WEBLIST% currently does not support "\n" or "$n" for new line, omitting separator will default to new line.

Another problem in your example is that TWiki does not match the correct curly bracket, the closing %WEBLIST% bracket is incorrectly matched by the closing bracket of %INCLUDE% (based on a simple non-greedy regex)

%SEARCH% has more options, this is probably what you want to use. Example: We search for topic names in all public webs and show the result in BookView.

%SEARCH{ "^WebStatistics[^a-zA-Z]" scope="topic" web="all" regex="on" bookview="on" nosearch="on" noheader="on" nototal="on" }%

If you want to go fancy you could specify a FormattedSearch with a regular expression instead of the BookView to pick a subset from the topic. Edit the Codev.WebHome topic to see how to show only the statistics of the current month.

Thanks, that's exactly it. I'd actually arrived at the recipie independently.

Followup -- I note that the terminator for "WebStatistics" is "[!a-zA-Z]" (actually, I used [^A-z0-9]), rather than "$". Is there a reason that the end-of-line metacharacter isn't appropriate? Hmm...probably a FAQ I'll bet

I can't remember the exact reason, but $ at the end does not seem to work in TWiki, hence [^A-z0-9].

Line end match is now fixed, see Codev.CantAnchorSearchREToEnd
