  6. I am the Amber CLI (CommandLine Interface) tool which runs on Node.js.
  7. My responsibility is to start different Amber programs like the FileServer or the Repl.
  8. Which program to start is determined by the first commandline parameters passed to the AmberCli executable.
  9. Use `help` to get a list of all available options.
  10. Any further commandline parameters are passed to the specific program.
  11. ## Commands
  12. New commands can be added by creating a class side method in the `commands` protocol which takes one parameter.
  13. This parameter is an array of all commandline options + values passed on to the program.
  14. Any `camelCaseCommand` is transformed into a commandline parameter of the form `camel-case-command` and vice versa.!

  79. I am the Amber Smalltalk FileServer.
  80. My runtime requirement is a functional Node.js executable.
  81. To start a FileServer instance on port `4000` use the following code:
  82. FileServer new start
  83. A parameterized instance can be created with the following code:
  84. FileServer createServerWithArguments: options
  85. Here, `options` is an array of commandline style strings each followed by a value e.g. `#('--port', '6000', '--host', '0.0.0.0')`.
  86. A list of all available parameters can be printed to the commandline by passing `--help` as parameter.
  87. See the `Options` section for further details on how options are mapped to instance methods.
  88. After startup FileServer checks if the directory layout required by Amber is present and logs a warning on absence.
  89. ## Options
  90. Each option is of the form `--some-option-string` which is transformed into a selector of the format `someOptionString:`.
  91. The trailing `--` gets removed, each `-[a-z]` gets transformed into the according uppercase letter, and a `:` is appended to create a selector which takes a single argument.
  92. Afterwards, the selector gets executed on the `FileServer` instance with the value following in the options array as parameter.
  93. ## Adding new commandline parameters
  94. Adding new commandline parameters to `FileServer` is as easy as adding a new single parameter method to the `accessing` protocol.!
