A mustache template parser library.

Allows parsing and rendering template files with mustache markup. See the mustache language reference.

Implements the mustache spec version 1.1.3.

Note: Versions including and beyond 0.4 are compatible with ghc 7.8 again.

mustache

Haskell implementation of mustache templates.

Implements the official specs version 1.1.3

Motivation

The old Haskell implementation of mustache templates hastache seemed pretty abandoned to me. This implementation aims to be much easier to use and (fingers crossed) better maintained.

Since it is so easy to use and requires but a few files of code, I've also written a small executable that compiles and renders mustache templates with data input from json or yaml files.

Usage

Library

Please refer to the documentation on hackage.

Executable haskell-mustache

$ haskell-mustache --help
Simple mustache template substitution

arguments [OPTIONS] TEMPLATE [DATA-FILES]

Common flags:
  -t --templatedirs[=DIRECTORY]  The directory in which to search for the
                                 templates
  -? --help                      Display help message
  -V --version                   Print version information

Current implementation substitutes the TEMPLATE once with each DATA-FILE

Example

$ haskell-mustache my-template-file data-file-1.json data-file-2.json data-file-3.json

Roadmap

• [x] String parser for mustache templates
• [x] Template substitution
• [x] Standalone executable
• [x] Support for 'set delimiter'
• [x] More efficiency using Text rather than String
• [x] More efficient Text parsing
• [x] Test coverage provided via the official specs
• [x] Haddock documentation
• [ ] More instances for ToMustache typeclass.
