Test fail with Clojure 1.6 (escaping backslashes)

[pesterhazy]

The unit test fail with current Clojure 1.6. It looks like a change between 1.4 and 1.5 broke the escaping of backslashes in the code. Maybe something related to the handling of regular expressions?

(render "{{{data}}}" {:data "\\"}) yields "\", not "\" as expected. Seems to be the same root cause. Tested with Clojure 1.7.0.

+1, I encountered the same error with rendering dollar signs.

user=> (println (mustache/render "{{money}}" {:money "$400.00"}))
\$400.00
nil
user=> (println (mustache/render "{{{money}}}" {:money "$400.00"}))
\$400.00
nil

This is with clojure-1.7.0 and clostache-1.4.0

With Clojure 1.8 and Clostache 1.4 I currently get:

(render "{{data}}" {:data "\\"})
=> "\\\\"
(render "{{data}}" {:data "$"})
=> "\\$"

I would expect \ and $

I am having the same issue.

I've resolved this issue in my fork of clostache: https://github.com/fotoetienne/cljstache

Sorry, forgot about this... But better late than never. There was apparently indeed some change in Clojure 1.5 that broke this. I've made a quick fix inspired by @fotoetienne's changes for now, but I'm still curious why this broke, couldn't find anything obvious.
