Here's a quick implementation:
template=:1 :0
assert. -. 0 e. }., I. '{}' =/ m NB. {} syntax check
assert. (,2) -: }.$y NB. need two cols: names; values
nams=. {."1 ,.y
vals=. {:"1 ,.y
subst=. vals {::~ nams i. <a
;(+/\@e.&'{}' <@({. subst@]^:('{'=[) }.)/. ]) m
)
Example use:
'{this} food' template ,:'this';'that'
that food
or, given
example=: 0 :0 template
Hello {name},
Nice to meet you.
{date}
)
This would also be an example:
example (;:'name date'),.'George';'today'
