Create global template A global template can executed in any folder/path. To creat global template instead local template add "-g" after "-n":

jsht -n -g create class

First jsht will look for the template at "./.jshtTemplates" folder, if not found it will look search in the global template path.

Global template path Get

jsht config template location

Set

jsht config template location C:/Desenv/Templates

Require Modules Install your modules at ".jshtTemplates" folder, to see where ".jshtTemplates" is, execute command "jsht config template location". Any module installed at your ".jshtTemplates" folder will be accessible by require method in your template.

Require Files A js file can be called using require, by the relative path of the template file. Example:

require("./folder/fileToBeCalled");

Call Template from template

callTemplate("./otherTemplate.js", [], []);

or through command:

execShell("jsht otherTemplate");

The second parameter is an array of input arguments. The third parameter is an arrays of named arguments.

Build in functions

• execShell - execute command in the system
        params:
              command - command to be executed
              path - optional, folder to execute the command, if not provided it will be executed on the current folder.
  Example:

execShell("ls");
execShell("cd ..");

Input Args Aditional parameters will became arguments inside the template:

jsht create class MyClassName calculateAge

class <#=inputArgs[0]#>{
     <#=inputArgs[1]#>(){

	 }
}

Named Args Passing named parameters.

jsht create class -methodName calculateAge -className MyClassName

class <#=namedArgs["className"]#>{
     <#=namedArgs["methodName"]#>(){
		 
	 }
}
