        Tool for render configurations from few templates/sources.
        
        ## Getting Started
        
        These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
        
        
        ### Installing
        
        Install via [pypi](https://pypi.org/project/shaper/):
        
        ```
        pip install shaper
        ```
        
        
        ### Use cases
        Aim of shaper - make configuration management easier with templating, DSL and CMDBs.
        
        
        #### Step 1 - Convert existing project configurations to DSL
        
        ```
        cd myproject
        shaper read
        ```
        
        We will get `out.yml` file with DSL of our project configuration
        
        <details><summary>out.yml</summary>

          src:
            main:
              resources:

                  app.email.default_from: 'no-replay@my-domain.com'
                  app.lock.provider: 'redis'
                application-qa1.properties:
                  spring.cache.type: 'redis'

                application.properties:
                  app.init.enabled: 'true'
        ```
        
        </p>
        </details>
        
        
        #### Step 2 - Agregate common parameters with YAML anchor/alias
        
        Using YAML specification let's rewrite duplicating data with anchors/aliases
        
        <details><summary> out_refactored.yml </summary>
        <p>
        
        ```python
        mappings.yml:
          redis:
            - host: &redis_dev_host 'dev.111111.0001.use1.cache.amazonaws.com'
              db:
                dev1: &redis_dev1_dbname 0
                qa1: &redis_qa1_dbname 1
        
            - host: &redis_prod_host 'prod.0000000.0001.use1.cache.amazonaws.com'
              db:
                prod1: &redis_prod1_dbname 0
            
          common_properties: &common_properties
            spring.cache.type: 'redis'
            spring.redis.port: '6379'
            spring.redis.ssl: 'false'
            spring.redis.ttl.minutes: '30'
            spring.redis.available: 'true'
            app.init.enabled: 'true'
            app.email.support_address: 'support@my-domain.com'
            app.email.default_from: 'no-replay@my-domain.com'
            app.lock.provider: 'redis'
        
        my-backend:
          src:
            main:
              resources:
                application-dev1.properties:
                  <<: *common_properties
                  spring.redis.host: *redis_dev_host
                  spring.redis.database: *redis_dev1_dbname
        
                application-qa1.properties:
                  <<: *common_properties
                  spring.redis.host: *redis_dev_host
                  spring.redis.database: *redis_qa1_dbname
        
                application-prod1.properties:
                  <<: *common_properties
                  spring.redis.host: *redis_prod_host
                  spring.redis.database: *redis_prod1_dbname
        
                application.properties:
                  app.init.enabled: 'true'
        ```
        
        </p>
        </details>
        
        This datastructure after loads equal to previus version, but look much more pretty without duplicates parameters.
        
        
        #### Step 3 - Write properties from CMDB
        
        ```
        shaper write out_refactored.yml
        ```
        
        
        #### Step 4 - Enjoy
        
        Check diff with existing configuration, fix if something wrong and embed into your CD pipeline.
        
        
        ## Running the tests
        We are using tox to agregate all testing steps. Just run it in project repository. All merges runs tests in [travis](https://travis-ci.org/arno49/shaper). 
        
        ```
        tox
        ```
        
        
        ## Contributing
        
        If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.
        
        ### How to make a clean pull request
        
        Look for a project's contribution instructions. If there are any, follow them.
        
        - Create a personal fork of the project on Github ([howto](https://help.github.com/articles/fork-a-repo/)).
        - Clone the fork on your local machine. Your remote repo on Github is called `origin`.
        - Add the original repository as a remote called `upstream`.
        - If you created your fork a while ago be sure to pull upstream changes into your local repository.
        - Create a new branch to work on! Branch from `develop` if it exists, else from `master`.
        - Implement/fix your feature, comment your code.
        - Follow the code style of the project, including indentation.
        - If the project has tests run them!
        - Write or adapt tests as needed.
        - Add or change the documentation as needed.
        - Squash your commits into a single commit with git's [interactive rebase](https://help.github.com/articles/interactive-rebase). Create a new branch if necessary.
        - Push your branch to your fork on Github, the remote `origin`.
        - From your fork open a pull request in the correct branch. Target the project's `develop` branch if there is one, else go for `master`!
        - If the maintainer requests further changes just push them to your branch. The PR will be updated automatically.
        - Once the pull request is approved and merged you can pull the changes from `upstream` to your local repo and delete
        your extra branch(es).
        
        And last but not least: Always write your commit messages in the present tense. Your commit message should describe what the commit, when applied, does to the code – not what you did to the code.
        
        ## Versioning
        
        We use [versioneer](https://pypi.org/project/versioneer/) for versioning. For the versions available, see the [tags on this repository](https://github.com/arno49/shaper/tags).
