Escaping in groovy

escapinggroovy

I need a help in escaping in groovy

I have some string in text file like this #$commonTomcat620.max_threads$# These value i have to replace in runTime.

I used following code:

    def str = "#\$commonTomcat620.max_threads\$#"
    fileContents = fileContents.replaceAll("${str}","100");

This str is printin the values as #$commonTomcat620.max_threads$#. but not replacing in file. I tried withOut #$ . it is working.

Thanks.

You have a couple of options to escape the dollar sign:

This works (with dollar-slashy strings):

def str = $/#\$$commonTomcat620.max_threads\$$#/$

Or this (with single quote strings):

def str = '#\\$commonTomcat620.max_threads\\$#'

Other options probably exist too

Javascript – Escaping HTML strings with jQuery

There is also the solution from mustache.js

var entityMap = {
  '&': '&amp;',
  '<': '&lt;',
  '>': '&gt;',
  '"': '&quot;',
  "'": '&#39;',
  '/': '&#x2F;',
  '`': '&#x60;',
  '=': '&#x3D;'
};

function escapeHtml (string) {
  return String(string).replace(/[&<>"'`=\/]/g, function (s) {
    return entityMap[s];
  });
}

Groovy String to Date

The first argument to parse() is the expected format. You have to change that to Date.parse("E MMM dd H:m:s z yyyy", testDate) for it to work. (Note you don't need to create a new Date object, it's a static method)

If you don't know in advance what format, you'll have to find a special parsing library for that. In Ruby there's a library called Chronic, but I'm not aware of a Groovy equivalent. Edit: There is a Java port of the library called jChronic, you might want to check it out.
