A Basil template can be parsed from a plain string. Every Basil template is composed of distinct, interleaved and non-nested static-text and slots. The slots contain limited Clojure forms to express the filter-functions and dynamic data. Few examples:
| Template | Clojure data | Result |
|---|---|---|
| foo bar | {} | foo bar |
| foo <% num %> bar | {:num 45} | foo 45 bar |
| foo <% (inc num) %> bar | {:inc inc :num 45} | foo 46 bar |
| foo <% (inc (inc num)) %> bar | {:inc inc :num 45} | foo 47 bar |
foo <% (when-not (seq names) "No names!") %> bar |
{:names []} | foo No names! bar |
foo <% (when (seq names) (str-br names)) %> bar |
{:names ["Lucy" "Brian"]} | foo Lucy<br/> Brian<br/> bar |
foo <% (for-each [b names] (str "name=" b)) %> bar |
{:names ["Tom" "Jane" "Larry"]} | foo name=Tom name=Jane name=Larry bar |
foo
<% (for-each [a [1 2]
b names]
(str ":a=" a
", name=" b)) %>
bar |
{:names ["Tom" "Jane" "Larry"]} | foo :a=1, name=Tom :a=1, name=Jane :a=1, name=Larry :a=2, name=Tom :a=2, name=Jane :a=2, name=Larry bar |
Use basil.public/parse-compile to parse and compile a template and use
basil.public/render-template to render a compiled template.
Template groups can be created from directory or classpath. A slot in one
template can include an entire template dynamically using
<% (include "foo.basil") %>. You may also create additional context for
included template using <% (include "foo.basil" {:a 10 :b 20} {:items xs}) %>.
Use basil.public/make-group-from-directory and
basil.public/make-group-from-classpath to create template groups. Use
basil.public/render-by-name to render a template from a group.
