NAME

mustache - Mustache processor

SYNOPSIS

mustache <YAML> <FILE>
mustache --compile <FILE>
mustache --tokens <FILE>

DESCRIPTION

Mustache is a logic-less templating system for HTML, config files, anything.

The mustache command processes a Mustache template preceded by YAML frontmatter from standard input and prints one or more documents to standard output.

YAML frontmatter begins with --- on a single line, followed by YAML, ending with another --- on a single line, e.g.

---
names: [ {name: chris}, {name: mark}, {name: scott} ]
---

If you are unfamiliar with YAML, it is a superset of JSON. Valid JSON should work fine.

After the frontmatter should come any valid Mustache template. See mustache(5) for an overview of Mustache templates.

For example:

{{#names}}
  Hi {{name}}!
{{/names}}

Now let's combine them.

$ cat data.yml
---
names: [ {name: chris}, {name: mark}, {name: scott} ]
---

$ cat template.mustache
{{#names}}
  Hi {{name}}!
{{/names}}

$ mustache data.yml template.mustache
Hi chris!
Hi mark!
Hi scott!

If you provide multiple YAML documents (as delimited by ---), your template will be rendered multiple times. Like a mail merge.

For example:

$ cat data.yml
---
name: chris
---
name: mark
---
name: scott
---

$ cat template.mustache
Hi {{name}}!

$ mustache data.yml template.mustache
Hi chris!
Hi mark!
Hi scott!

OPTIONS

By default mustache will try to render a Mustache template using the YAML frontmatter you provide. It can do a few other things, however.

-c, --compile

Print the compiled Ruby version of a given template. This is the code that is actually used when rendering a template into a string. Useful for debugging but only if you are familiar with Mustache's internals.

-t, --tokens

Print the tokenized form of a given Mustache template. This can be used to understand how Mustache parses a template. The tokens are handed to a generator which compiles them into a Ruby string. Syntax errors and confused tags, therefore, can probably be identified by examining the tokens produced.

INSTALLATION

If you have RubyGems installed:

gem install mustache

EXAMPLES
