Example :

$ cracker client --starts-with Array.e

Outputs all the Array class methods starting with e :

{
  "status": "success",
  "results": [
    {
      "name": "Array.each_product(arrays)",
      "file": "/path/to/crystal/source/array.cr",

    }
  ]
}
$ cracker client --starts-with Array#e

Development

  • Allow to search using starts_with?
  • Add line number to the result
  • Replate type by a string
  • Daemonize
  • Append new source path for completion ( project path for instance )
  • Method completion
  • Enum completion
  • Macro completion
  • Alias Completion
  • Lib completion
  • Constants completion
  • IDE integration
