Once again, the syntax is different inside a filter. When referencing a
variable, use ...regexp<variable>...
However, since you're really just looking for a prefix, maybe use the
prefix operator (prefix[]). Here's how I could do what you wanted using the
prefix operator and a variable (catcolon) to concatenate the colon:
\define catcolon() $(pfix)$:
<$set name=pfix value={{!!title}}>
<$list filter=
"[!has[draft.of]tag[task]!tag[done]sort[created]prefix<catcolon>]">
<$checkbox tag="done"> <$link to={{!!title}}><$view field="title"/></$link
></$checkbox>
</$list>
</$set>
If you wanted to concatenate a title with a tilde, then you could use
instead:
\define cattilde() $(pfix)$~
<$set name=pfix value={{!!title}}>
<$list filter=
"[!has[draft.of]tag[task]!tag[done]sort[created]prefix<cattilde>]">
<$checkbox tag="done"> <$link to={{!!title}}><$view field="title"/></$link
></$checkbox>
</$list>
</$set>
