Hi, I know that TW syntax can be overwhelming. Let's cut this back to its simplest form.
Macros are used primarily for Text Replacement. That is, then the macro is "called" the wiki-text parser tries to complete all text replacement in the macro-body using the inputs, and _then_ it parses the resulting text AS wikitext as per normal. So the simplest implementation would be (note the use of the "ext" modifier for the link quick-syntax, this forces an external link): ``` \define wcagTechUrl(ref) [ext[$ref$|https://www.w3.org/WAI/WCAG21/Techniques/$ref$]] \end <<wcagTechUrl H96>> ``` While it is now easy to write these macro-links via plaintext, you would not want to use this form inside a $list or other widget construction. Use the below pattern instead. I have "unpacked" the macro-call quick-syntax. This allows us to pass other variables or tranclusions to the input of the macro. In this case the tiddler title of any tiddler tagged "wcagTechUrl" in a $list construction (using the default "currentTiddler" variable by omitting the "variable" parameter of the $list): ``` \define wcagTechUrl(ref) [ext[$ref$|https://www.w3.org/WAI/WCAG21/Techniques/$ref$]] \end <$list filter="[tag[wcagTechUrl]]"> <$macrocall $name=wcagTechUrl ref=<<currentTiddler>> /> </$list> ``` Best, Joshua Fontany On Sunday, September 20, 2020 at 3:30:48 PM UTC-7 [email protected] wrote: > I want to generate URL.
