Robin, This is an area with a gap in the doco, I is hard to find it in one place. here are a few

The double-bracket syntax is used to avoid conflicts with standard HTML syntax (i.e., <b> starts normal HTML bold formatting, while <<b>> embeds the value of a TiddlyWiki variable named "b") However, within TiddlyWiki *filters*, there is no need doubling the brackets, as HTML is not allowed *within* the filter, so only single <variableName> is used. ...and why I don't have to wrap <fieldname> with [<fieldname>] before giving it to split. Think of the brackets in filters as part of the operand itself rather than a "container" for the operand. The type of bracket indicates the type of operand being used: use [...] for literal values, e.g., [texthere] use {...} for field references, e.g., {!!fieldname} use <...> for variables e.g. <currentTiddler> Thus, to split the literal text, "sometext", you could write: [title[sometext]splitbefore[t]removesuffix[t]] you would get "some" as a result. If the value "sometext" is stored in a field named "somefield" in the current tiddler, you could write: [{!!somefield}splitbefore[t]removesuffix[t]] and, if the value "sometext" is stored in a variable named "somevariable", you could write: [<somevariable>splitbefore[t]removesuffix[t]] As a slightly more complex example, suppose the value to split on was also stored in a variable. Then you could write: [<somevariable>splitbefore<othervariable>removesuffix<othervariable>] Regards Tony On Tuesday, May 1, 2018 at 11:46:37 AM UTC+10, Robin wrote: > > Yay it works thanks a lot for this. > > Also good tip for the macro names, I didn't think of that. > > But I still don't know why this works. > can I allways replace [ ] with { } in a filter ? > > That part of the syntax eludes me a bit. > > > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
