generation framework

#hero generate -p thepath_is_optional
##hero generate -p thepath_is_optional -t client
#hero generate -p thepath_is_optional -t installer

#hero generate -p thepath_is_optional -t installer -s

there will be a .heroscript in the director you want to generate for, the format is as follows:

//for a server
!!hero_code.generate_installer
    name:'daguserver'
    classname:'DaguServer'
    singleton:1            //there can only be 1 object in the globals, is called 'default'
    templates:1            //are there templates for the installer
    default:1              //can we create a default when the factory is used
    title:''
    supported_platforms:'' //osx, ... (empty means all)
    reset:0                 // regenerate all, dangerous !!!
    startupmanager:1      //managed by a startup manager, default true
    build:1                 //will we also build the component

//or for a client

!!hero_code.generate_client
  name:'mail'
  classname:'MailClient'
  singleton:0            //default is 0
  default:1              //can we create a default when the factory is used
  reset:0                 // regenerate all, dangerous !!!

needs to be put as .heroscript in the directories which we want to generate

templates remarks

in templates:

• ^^ or @@ > gets replaced to @
• ?? > gets replaced to $

this is to make distinction between processing at compile time (pre-compile) or at runtime.

call by code

to call in code

import freeflowuniverse.crystallib.core.generator.installer

installer.scan('~/github/freeflowuniverse/crystallib/crystallib')!

fn create_heroscript(args GeneratorArgs) !

fn generate(args_ GeneratorArgs) !

will ask questions when not in force mode & generate the module

fn scan(args_ GeneratorArgs) !

scan over a set of directories call the play where

enum Cat {
	installer
	client
}

struct GeneratorArgs {
pub mut:
	name                string
	classname           string
	default             bool = true // means user can just get the object and a default will be created
	title               string
	supported_platforms []string // only relevant for installers for now
	singleton           bool     // means there can only be one
	templates           bool     // means we will use templates in the installer, client doesn't do this'
	reset               bool     // regenerate all, dangerous !!!
