Hi Mat, I know this is an old thread but I just wanted to add my solution.
If you only want to concatenate variables, macros and literals (but no transclusions), you can use the following technique, which allows you to dynamically concatenate strings without having to specifiy the concatination in the concat macro itself: \define concat(str) $str$ <<concat "Hi my name is $(currentTiddler)$ I like TW $(version)$.">> This technique makes use of TW's ability to parameterize variable calls. *The trick is to inject the whole macro body as string.* So we refer to variables and macros via $(…)$ notation and embedd everything in a single string that is then passed to the concat macro as param. This has a huge advantage over hardcoding the macro body. <$set name="url" value=<<concat "http://foo.com/# <http://foo.com/#> :$(currentTiddler)$">>> <$set name="url" value=<<concat "http://foo.com/# <http://foo.com/#>:$(currentTiddler)$ Hello world $(version)$">>> You see the advantage? you can use the same single concat macro for several dynamic concatination tasks -Felix -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
