Lightweight Clojure library for simple string templating?

There are quite a lot of templating libraries. Some general purpose ones are:

• clostache
• comb
• selmer

Note: If you just need to have some clever formatting, you have the standard library clojure.pprint with the cl-format function and clojure.core/format which is the wrapper around java.util.Formatter.

You can use the << string interpolation macro from the core.incubator project.

To use it, add [org.clojure/core.incubator "0.1.4"] as a dependency in your project.clj file. (Note: check core.incubator's GitHub page for the latest installation instructions.)

Example use:

(ns example
  (:require [clojure.core.strint :refer [<<]]))

(def my-name "XYZ")
(<< "My name is ~{my-name}.")
; Returns: "My name is XYZ."

(let [x 3
      y 4]
  (<< "~{x} plus ~{y} equals ~(+ x y)."))
; Returns: "3 plus 4 equals 7."

Note the difference between the use of curly braces ~{} and parentheses ~().
