After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
Example YAML-File:
yq - Usage:
It's already available via repository in newer versions of major linux distributions

MUSTACHE(1) Mustache Manual MUSTACHE(1)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 beings 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}}
$ cat data.yml template.mustache | 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}}!
$ cat data.yml template.mustache | 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, therefor, can probably be identified
by examining the tokens produced.
INSTALLATION
If you have RubyGems installed:
gem install mustache
EXAMPLES
$ mustache data.yml template.mustache
$ cat data.yml | mustache - template.mustache
$ mustache -c template.mustache
$ cat <<data | ruby mustache - template.mustache
