TWC is located at http://classic.tiddlywiki.com ... everything at http://tiddlywiki.com is for TW5... the documentation you mention is for TW5 syntax ONLY. use case: > list all tiddlers tagged 'History' in chronological order, that is, fields > start_date end_date link-to-tiddler ordered by end_date (reverse). > This can be done with ForEachTiddler, which takes javascript fragments as parameter "clauses" (where, sortby, write, start, end, script). The macro inserts those code fragments into a 'harness' loop that retrieves all tiddlers, applies the "where" clause test to select tiddlers, and then sorts and writes output based on that selected list. However... the syntax for ForEachTiddler can be a bit fussy, because the enclosing macro syntax makes use of quotes around the parameter values, so quotes *within* the code fragments can get problematic: if you use double-quotes around the parameter, you can only use single-quotes within the parameter value. Fortunately, there is another way to write custom "select and output" handling... using plain Javascript. First, install this plugin: http://www.TiddlyTools.com/#InlineJavascriptPlugin This plugin extends the TWC parser so that it can recognize <script>...</script> blocks within tiddler content, which it passes on to the browser's javascript engine for processing. Within the script, you can invoke any TWCore functions you need to select/sort tiddlers and access their field values to generate output text, which is then returned at the end of the script and rendered ("wikified") by the TWCore. For your purposes, the following script should do what you want: ------------- <script> var tag="History"; var srt="-end_date"; var out=""; var hdr="|!start|!end|!title|\n"; var fmt="|%0|%1|[[%2]]|\n"; var tids=store.sortTiddlers(store.getTaggedTiddlers(tag),srt); if (tids.length) out+=hdr; for (var i=0; i<tids.length; i++) out+=fmt.format([tids[i].start_date,tids[i].end_date,tids[i].title]); return out; </script> ------------- Notes: * start by defining some variables (mostly for readability): the tag to match, the sort field (the "-" prefix means reverse order), the output buffer, a heading for table columns, and the format for output of table rows * retrieve the tiddlers that match the tag, and sort them. * if there are any matching tiddlers, output a table heading * loop through the matched tiddlers and output the start/end dates and linked title * return the buffered output enjoy, -e Eric Shulman TiddlyTools / ELS Design Studios YOUR DONATIONS ARE VERY IMPORTANT!
