bbmustache

Binary pattern match Based Mustache template engine for Erlang/OTP.

What is Mustach ?

A logic-less templates.

• {{mustache}}

Overview

• Binary pattern match based.
• Do not use a regular expression !!
• Support maps and associative arrays.

Usage

Quick start

$ git clone git://github.com/soranoba/bbmustache.git
$ cd bbmustache
$ make start
Erlang/OTP 17 [erts-6.3] [source-f9282c6] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:true]

Eshell V6.3  (abort with ^G)
1> {ok,[bbmustache]}
1> bbmustache:render(<<"{{name}}">>, #{"name" => "hoge"}).
<<"hoge">>
2> bbmustache:render(<<"{{name}}">>, [{"name", "hoge"}]).
<<"hoge">>

Use as a library

Add the following settings.

%% rebar.config

{deps,
  [
   {bbmustache, ".*", {git, "git://github.com/soranoba/bbmustache.git", {branch, "master"}}}
  ]}.

If you don’t use the rebar and use the OTP17 or later, this library should be compile with -Dnamespaced_types.

How to use simple Mustache

• Mastache Manual
• Support all of syntax !

Map (R17 or later)

1> bbmustache:render(<<"{{name}}">>, #{"name" => "hoge"}).
<<"hoge">>

2> Template1 = bbmustache:parse_binary(<<"{{name}}">>).
...
3> bbmustache:compile(Template1, #{"name" => "hoge"}).
<<"hoge">>

4> Template2 = bbmustache:parse_file(<<"./hoge.mustache">>).
...
5> bbmustache:compile(Template2, #{"name" => "hoge"}).
<<"hoge">>

Associative array

1> bbmustache:render(<<"{{name}}">>, [{"name", "hoge"}]).
<<"hoge">>

2> Template1 = bbmustache:parse_binary(<<"{{name}}">>).
...
3> bbmustache:compile(Template1, [{"name", "hoge"}]).
<<"hoge">>

4> Template2 = bbmustache:parse_file(<<"./hoge.mustache">>).
...
5> bbmustache:compile(Template2, [{"name", "hoge"}]).
<<"hoge">>

Attention

• Lambda expression is included wasted processing.
• Because it is optimized to parse_string/1 + compile/2.
