Inspired byctemplate andet,Mustache is aframework-agnostic way to render logic-free views.

As ctemplates says, "It emphasizes separating logic from presentation:it is impossible to embed application logic in this template language."

CL-MUSTACHE is a Common Lisp implementation of Mustache v1.1.2+λ. Tested with:

• SBCL 1.0.55
• CLISP 2.49

CL-MUSTACHE is semantically versioned:http://semver.org.

The different Mustache tags are documented atmustache(5).

Using quicklisp is recommended.

CL-USER> (ql:quickload "cl-mustache")

Currently accepts context data in alist format, for example:

`((:tag . "string")  (:array . #(1 2 3 4))  (:lambda ,(lambda () "world"))  (:nested . ((:data . t))))

To render the template:

CL-USER> (mustache:render* "Hi {{person}}!" '((:person . "Mom")))"Hi Mom!"

Or save the renderer for later use:

CL-USER> (setf view (mustache:compile-template "Hi {{person}}!"))

Or define static renderer function:

CL-USER> (mustache:define view "Hi {{person}}!")CL-USER> (view context)

CL-USR> (ql:quickload "cl-mustache-test")CL-USR> (prove:run :cl-mustache-test)

Define your tag classes, tag character and render function:

(in-package :mustache)(defclass exec-tag (non-standalone-tag)  ((command :initarg :command :accessor command)))(set-mustache-character  #\$  (lambda (raw-text arg-text escapep start end)    (make-instance 'exec-tag :command arg-text)));; or;; (define-mustache-character #\$;;   (make-instance 'exec-tag :command arg-text))(defmethod render-token ((token exec-tag) context template)   (print-data (run-program-output (command token)) t context))
