New Velocity tools and methods
Aug 14, 2020
New Regex Tool
A new Regex Tool allows you to compile regular expressions for comparison and matching use. Example:
$_RegexTool.compile("^[a-zA-Z0-9]*$")
#set ($text = "A string to search for links containing the pattern https:// .")
#set ($patternString = ".*https://.*")
#set ($pattern = $_RegexTool.compile($patternString))
#set ($matcher = $pattern.matcher($text))
#set ($matches = $matcher.matches())
## Expected output: true
New String Tool methods
If you need to create unique IDs for elements such as element id
attributes, you can now generate universally unique identifiers with the .generateUUID()
method. Example:
$_StringTool.generateUUID()
## Sample output: 29ecf0f3-7db4-41b5-94a2-3e170338c3b5
We've also added a new method to build Strings. Example:
#set ($stringBuilder = $_StringTool.getStringBuilder())
#set ($_void = $stringBuilder.append("foo"))
#set ($_void = $stringBuilder.append("+"))
#set ($_void = $stringBuilder.append("bar"))
$stringBuilder
## Sample output: foo+bar
New Escape Tool methods
We've added several new methods to unescape HTML, JavaScript, and XML markup. Examples:
$_EscapeTool.unescapeHtml('Here is a String with an escaped ampersand (&).')
## Expected output: Here is a String with an escaped ampersand (&).
$_EscapeTool.unescapeJavaScript('if (i === \"foo\")')
## Expected output: if (i === "foo").
$_EscapeTool.unescapeHtml('<foo>bar</foo>')
## Expected output: <foo>bar</foo>
