plustache - mustache templates for C++

Basic port of mustache templating to C++.

Motivation

I just wanted to port mustache and build simple templating for C++. And I am still trying hard to keep it simple.

Usage

Simple Usage

Create a template:

<h1>{{title}}</h1>
Hi I am {{name}}.
I like {{thing}}.

Fill the context:

#include <string>
#include <plustache/plustache_types.hpp>
#include <plustache/template.hpp>

using std::string;
using PlustacheTypes::ObjectType;
using Plustache::template_t;

ObjectType ctx;
ctx["title"] = "About";
ctx["name"] = "Daniel";
ctx["thing"] = "turtles";

Instantiate template class and render the template:

template_t t;
string template("<h1>{{title}}</h1>\nHi I am {{name}}.\nI like {{thing}}.");

string result = t.render(template, ctx);

Result:

<h1>About</h1>
Hi I am Daniel.
I like turtles.

Advanced Usage

Create the template:

<h1> {{title}} </h1>
<ul>
    {{# friends}}
      <li> {{name}}</li>
      <li> {{job}}</li>
      <li> {{status}}</li>
    {{/ friends}}
</ul>

Create the context:

// create types
context ctx;
CollectionType c;
ObjectType jim;
ObjectType john;
ObjectType jack;
// Fill values
ctx.add("title", "My friends");
jim["name"] = "Jim";
jim["job"] = "Wizard";
jim["status"] = "Eating";
john["name"] = "John";
john["job"] = "Rainbow Painter";
john["status"] = "Sleeping";
jack["name"] = "Jack";
jack["job"] = "Unicorn Trainer";
jack["status"] = "Riding";
// enter data
c.push_back(jim);
c.push_back(john);
ctx.add("friends", c);
// also possible
ctx.add("friends", jack);

Render the template:

template_t t;
string result = t.render(template, ctx);

Installation

There are packages available for some Linux distributions on Packagecloud.

Otherwise clone this repository and run the manual install task:

git clone git://github.com/mrtazz/plustache.git
autoreconf -i
./configure
make
make install

On OSX you can get it via my homebrew tap:

brew tap mrtazz/oss
brew install plustache

Running the unit tests

Build the google test library:

cd vendor/gtest-1.7.0
./configure
make

On OS X, you may get an error:

vendor/gtest-1.7.0/include/gtest/internal/gtest-port.h:499:13: fatal error:
'tr1/tuple' file not found
#   include <tr1/tuple>  // NOLINT

If so, re-run configure with the following argument

./configure CPPFLAGS=-DGTEST_USE_OWN_TR1_TUPLE=1
make

Build the test program

Run this from the top-level plustache source directory:

make test-program

If you get the tr1/tuple error, do:

./configure CPPFLAGS=-DGTEST_USE_OWN_TR1_TUPLE=1
make test-program

Run the test program

./test-program

Building with Microsoft Visual Studio

The supplied MSBuild files will look for an installation of boost in the parent directory of this repo. The boost regex library must be built. For example:

cd boost_1_55_0
bootstrap
b2 -j8 toolset=msvc-12.0 address-model=64 --with-regex --prefix=../boost install

The boost directories and other build parameters can be configured by creating a Directories.targets file.

The gtest project files are generated by cmake. Use a command like this to recreate the gtest project files:

cd msvc/x64/msvc120/gtest
cmake -G "Visual Studio 12 Win64" ../../../../vendor/gtest-1.6.0 -Dgtest_force_shared_crt=ON
