You can use all sorts of clever javascript code within an evaluated
parameter to assemble a value from a combination of literals and variables.
It all depends on how your input value is stored. For simplicity, let's
suppose you use the TWCore <<option txtSomeName>> syntax to enter an
"option" value. Then, in the eval param javascript, you can refer to:
config.options.txtSomeName to retrieve the value you entered.
Thus, you could write:
<<newTiddler label:'make foo'
title:{{'foo-'+config.options.txtSomeName+*'*: *My title text*'}}
text:{{'<<baz *'+*config.options.txtSomeName*+'*>>'}} >>
HOWEVER... this is still problematic... because the eval params in the
<<newTiddler>> macro are calculated when the macro is *rendered*... not
when it is clicked on. Thus, the param values that are used will not
change if you enter a new value in the <<option txtSomeName>> input field.
Fortunately, I've already solved this problem! Start by installing this
plugin:
http://www.TiddlyTools.com/#ClickifyPlugin
Then, add "clickify" to the start of your macro, like this:
<<clickify newTiddler label:'make foo'
title:{{'foo-'+config.options.txtSomeName+*'*: *My title text*'}}
text:{{'<<baz *'+*config.options.txtSomeName*+'*>>'}} >>
This causes the macro to recalculate the eval params each time the
corresponding link (e.g., "new tiddler") is clicked, so that the params are
always constructed usnig the current values of any input variables (e.g.,
config.options.txtSomeName).
