Working with groovy is really a cake walk. Whenever I get some free time I try to know more about it. Today I was just wondering on the net and I found some cool tips to execute groovy file in grails. There are so many other ways available to run groovy script in grails, I will share one of the way to do it.<\/p>\n
To know it we will take a very simple example like we have a groovy script CapitalizeWords.groovy which capitalize all the words of the arguments. The script is like this <\/p>\n
[java]
\nList words=[]
\nthis.args.each{arg->
\n\targ.split().each{
\n\t\twords.add(it.toUpperCase())
\n\t}
\n}<\/p>\n
return words
\n[\/java]<\/p>\n
Now we will call this script in one of our action like this <\/p>\n
[java]
\ndef someAction ={
\n File file = new File("${servletContext.getRealPath("\/")}CapitalizeWords.groovy")
\n GroovyShell groovyShell = new GroovyShell()
\n def result = groovyShell.run(file, ["Hello ", "this is ", "uday ", "saying Hii to you"])
\n render "——${result}——"
\n}
\n[\/java]<\/p>\n
The output for this would be
\n[java]
\n——[HELLO, THIS, IS, UDAY, SAYING, HII, TO, YOU]——
\n[\/java]<\/p>\n
In run method of GroovyShell class you pass the file that need to execute and the list of arguments.
\n<\/p>\n
