Build Status

Sceleton is a simple tool for scaffolding directories and files using user-inputted data.

Running Sceleton

Sceleton can be run using a variety of methods:

As a docker container

Coming soon!

As a standalone program

Coming soon!

As an SBT plugin

Coming soon!

Within a JVM-based program

Lastly, you can use Sceleton directly by taking a dependency on sceleton-core and calling the runner manually:


val config = 
        prefilledProps = Map("name" -> "test service")

new SceletonRunner(config).run() match {
    case Success(_) => 
    case Failure(ex) => 

Writing templates

Write templates using any of the supported templating languages. File names are also considered when applying templates.

When given a directory, Sceleton will search for the deepest directory that ends with the word sceleton. This is treated as the scaffold root; nothing above the root is transformed and only files/directories under the root are outputted to the target directory.

Supported template sources:

  • Local filesystem
  • Github (or any git repository)

Supported template engines:

  • Mustache


There is support for textual transforms on templated values. Transforms can also be chained together.

Simple transform to lowercase:

{{ name;format="lower" }}

Chained transforms:

# transforms "Bob Smith" to "bob_smith"
{{ name;format="lower,underscore" }}

Available transforms

  • camel - Converts a string to "camelCase"
  • Camel - Converts a string to "CamelCase/PascalCase"
  • start|start-case - Capitalizes the first letter in each word
  • underscore|snake|snake-case - Converts a string to snake_case (replaces dots and spaces with underscores)
  • hyphenate|hyphen - Replaces spaces with hypens
  • normalize|norm - Compound transform: runs lower-case and then hyphenate on a string
  • packaged|package-dir - Replaces dots with slashes; useful for generating directory trees
  • upper|upper-case - Converts an entire string to uppercase
  • lower|lower-case - Converts an entire string to lowercase
  • cap|capitalize - Capitalizes the first letter of a string
  • decap|decapitalize - Un-capitalizes the first letter of a string
  • word|word-only - Removes all non-word characters in a string
  • random|generate-random - Generates a random alphanumeric string of length 10

Defining variables

Variables for a scaffold are defined in a file entitled in the template root. This file uses the standard format for a properties file. The special key description can be used to print a message to the user during scaffold time.

Planned features

  • Run options
    • SBT Plugin
    • Docker container for running with no required Java setup
    • Standalone app (Assembly JAR)
  • Scaffold options
    • Change mustache delimiter
    • Change transform delimiter
    • Support pluggable renderer (engines other than Mustache)
    • Support pluggable transforms (would only be available for code-based executions, e.g. SBT, direct)
