A Haskell implementation of mustache templates. Expects input data to be JSON.

Should be compatible with the the mustache specification. Except lambdas are not supported.

Supported syntax:

• basic variables
• sections
• inverted sections
• comments (are suppressed)
• partials
• set delimiter

This project currently only provides a command line interface. Later versions will provide a library API for templating ToJSON instances.

You need the Haskell platform on your system.

cabal install mustache-haskell 

Or alternatively

git clone git@github.com:danchoi/mustache-haskell.git cd mustache-haskell cabal sandbox init cabal install # Now copy .cabal-sandbox/bin/mus to your PATH 

mus template.mustache < input.json 

mus Usage: mus [-c] [-d TEMPLATE_DIRECTORY] TEMPLATE_FILE A Haskell implementation of Mustache templates. On STDIN provide the JSON to insert into the template. Available options: -h,--help Show this help text -c Just output parse tree of template file -d TEMPLATE_DIRECTORY Template directory 

mustache-haskell adds one additional feature to the mustache specification. If you are outputing elements of a list, you can designate an optional list separator with the following syntax:

{{#hobbies, }}{{name}}{{/hobbies}} 

This designates ", " as the list separator and will output

sewing, brewing, cooking 

when the input is

{"hobbies":[{"name":"sewing"},{"name":"brewing"},{"name":"cooking"}]}

In a few informal tests,

mus template.mustache < input.json 

is about 10x faster than the Ruby mustache gem command-line implementation,

mustache - template.mustache < input.json
