I'm using clj-pdf to generate pdf files. As the README
file suggests, the library provides some rudimentary templating options.
For example, given a vector of maps, such as:
(def employees
[{:country "Germany",
:place "Nuremberg",
:occupation "Engineer",
:name "Neil Chetty"}
{:country "Germany",
:place "Ulm",
:occupation "Engineer",
:name "Vera Ellison"}])
and a template
(def employee-template
(template
[:paragraph
[:heading $name]
[:chunk {:style :bold} "occupation: "] $occupation "\n"
[:chunk {:style :bold} "place: "] $place "\n"
[:chunk {:style :bold} "country: "] $country
[:spacer]]))
The following output will be produced:
(employee-template employees)
([:paragraph [:heading "Neil Chetty"]
[:chunk {:style :bold} "occupation: "] "Engineer" "\n"
[:chunk {:style :bold} "place: "] "Nuremberg" "\n"
[:chunk {:style :bold} "country: "] "Germany" [:spacer]]
[:paragraph [:heading "Vera Ellison"]
[:chunk {:style :bold} "occupation: "] "Engineer" "\n"
[:chunk {:style :bold} "place: "] "Ulm" "\n"
[:chunk {:style :bold} "country: "] "Germany" [:spacer]])
However, I'm wondering how to use this template in pdf
function. When I use
(pdf
[[:heading "Heading 1"]
[:table
{:width 100 :border false :cell-border false :widths [30 70] :offset 35}
[[:cell {:align :right}
(employee-template employees)]
[:cell "dummy"]]]
[:heading "Heading 2"]]
"output.pdf")
I got a invalid tag
exception.
If I change (employee-template employees)
to (first (employee-template employees))
, it works however not as I expect. What is the correct way to use a template?
