cfn-include

• Add optional index variable to Fn::Map and Fn::Length to obtain the length of a list (@arjanvandervelde)
• Add Fn::DeepMerge (@nmccready)

• Add support for Fn::Sequence

Breaking changes:

• aws-sdk is now a peer dependency
• dropped support for NodeJS 4 and 6

Features:

• you can now provide a --bucket parameter which allows you to validate templates > 50k
• Validation errors are now pretty-printed without a full stack trace

Housekeeping:

• replace nomnom with yargs

• Renamed !GetCidr to !Cidr after AWS changed their mind on how to name that function 😞 (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-cidr.html)

• Fixed broken response when using --validate

• Added !GetCidr intrinsic function to the schema (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-getcidr.html)

Breaking Changes:

• With this release we are dropping support for NodeJS < 4.0.0.
• We no longer create a Metadata key in the output template. If you want to depend on this feature, pass the --metadata flag. See #30.
• Previously, we used request to load includes from HTTP and HTTPS endpoints. This has now been replaced with the node built-in http and https libraries.

Features:

• When outputting to yaml, keys are now sorted. This will allow to generate meaningful diffs between templates.
• templates can now be read from stdin e.g. passed from another preprocessor without writing to a temporary file: cat mytemplate.yml | cfn-include --validate --yaml
• the api type now recognizes the AWS region provided by the AWS_REGION and AWS_DEFAULT_REGION environmental variables. If none are defined, it defaults to us-east-1.
• Fn::Merge will now merge it's output into its parent object instead of replacing it

New Features:

• Fn::Stringify takes a data structure and converts it into a JSON string

Bug Fixes:

• do not exit the process in module code and capture unhandled exceptions in cli.js, #fixes 28

New Feature:

• new type: string introduced (thanks to @rschick) which makes it easier to include files as strings for use with Fn::Sub and without the infamous Fn::Join syntax.

Deprecated:

• type: literal is deprecated as Fn::Sub made working with Refs so much easier. Check out type: string, I've also updated the README to use type: string everywhere.
• Node < v4 is deprecated. AWS Lambda has deprecated their v0.10.42 runtime as well which was the only reason this module is still supporting this old version.

Fixed Bugs:

• If the included file was empty, cfn-include would go into an infinite loop. That has been fixed.

• cfn-include --version now exits with an exit code of 0
• YAML syntax now supports the shorthand !GetAtt Role.Arn which previously would have been written as !GetAtt [Role, Arn]
• Added support for !Split

Features:

• YAML is now fully supported and all CloudFormation tags such as !Ref are supported too

Bug Fixes:

• bail early if any of the Fn::Include calls fail

• Allow YAML for input templates and output

  Since JSON is YAML the YAML parser will happily accept JSON documents with YAML comments

• Fn::Include now supports AWS API calls, check out the examples

• support JMESPath queries returning literals instead of objects

• default to json for Fn::Include instead of undefined
• allow the first argument to Fn::Map to be interpreted, i.e. Fn::Include will work

• fixes #15

• add --version flag
• fixed synopsis to be a valid CFN template
• added documentation for how to use cfn-include web service (no installation required)
• reduced install footprint

• Fn::Map will now also replace variables in object keys
• added Fn::Merge which allows for very interesting use cases (e.g. define multi-az resources only once)
• added tests for the CLI
• fixed compatibility for Node.js 0.10

New features:

• allow for comments in the template (@hoegertn)
• query included template and only include a part of it (@hoegertn)
• include metadata in the generated template (git commit hash, timestamp)

Other:

• fix for Windows
• harden URL include somewhat (i.e. disallow redirects)
• make cfn-include work with npm link (@hoegertn)

Thanks @hoegertn for your support!

• added Fn::Map with support for nested maps
• added Fn::Flatten
• some code optimizations

• Performance improvements
• Proxy support for validate template
• Parse JSON with jsonlint for better syntax errors
• Tested with Node v0.10 and up
