Marathon Runner

Master: Build Status

The marathon runner is a very simple (and opinionated) nashorn runner that aims to be node friendly.

Our main goal is to have a battle tested production environment, while enjoying the benefits of using a better language and development environment.

Just to be clear this is NOT a complete node replacement, instead we want to be able to use npm (or bower) dependencies that don't depend a lot on the node runtime.

Now let's list our specific goals:

  • To be able to use CommonJS
  • To mimic NodeJS dependency resolution
  • To make reactive extensions interoperable with java
  • Just enough node to run coffee

Gradle Tasks

gradle cli:shadowJar It produces the fat jar

gradle prepareDist It copy the fat jar and adjust script with current versions

gradle buildZip It build a zip ready to use under build directory.

Marathon CLI

Usage: bin/marathon [options] [targetFile]

Options:

-h,--help Show usage information

-config,--config-file <configFile> Config file to use. If not specified uses ~/.marathon. Command line options has priority over config file ones.

Example: -config /home/marathon_file.config

-mp,--marathon-path <path> Specifies marathon path used to require modules. If not specified then current directory path is taken, and [current directory]/node_modules and environment variable $MARATHON_PATH

Example: -mp /one/path:/another/path

-im,--init-modules <modules> List of initial modules to load separated by (,) commas.

Example: -im $name:$path,fs:/path/fs,vm:/path/vm,domain

  • If $path is not specified then --init-modules-path is taken.
  • If --init-modules-path not specified then it uses the path corresponding to project resources.
  • Other valid values are [NONE|DEFAULT]

-imp,--init-modules-path <initModulesPath> Path taken in --init-modules when path is not specified explicitly

Example: -imp /path/to/init/modes

-mode,--editing-mode <mode> Edition mode [vi|emacs]

Example: -mode vi

-r,--reload-context If present, each evaluation is made with a different context

Example of config file (~/.marathon):

Command line options has priority over config file ones.

settings {

  // Mode vi or emacs
  editMode = 'vi'

  // Path for modules to require
  marathonPath = '/path/one/node_modules:/path/two/node_modules'

  // Map with initial modules to load and their respective paths
  initModules = 'fs,mv,domain:/path/domain'

  // Default path for initial modules if not specified in initModules path
  initModulesPath = '/init/modules/path'

}
Prompt commands

quit|exit|:quit|:exit|:q To close cli

:prompt <attempted promp> It sets the prompt symbol. Example :prompt >> set the prompt symbol to >>

:reload To ask for th ecurrent reload mode

:reload true, :reload false Changes the reload mode. If true the context is new for each evaluation

:clear Erase the screen

:settings To ask for the current settings

  • editMode EMACS or VI
  • marathonPath Specifies marathon path used to require modules
  • initModules Initial modules which were loaded [moduleName,pathWereToFindIt]
  • initModulesPath Path were initial modules are taken if initModules was not set
