Python string 'Template' equivalent in java

Question

Python supports the following operation:

>>> s = Template('$who likes $what')
>>> s.substitute(who='tim', what='kung pao')
'tim likes kung pao'

(Example taken from Python's official documentation )

Is there an equivalent way in Java for performing the exact task?

Thanks

Answer 1

Take a look at http://www.stringtemplate.org/ . Here is an example:

ST hello = new ST("Hello, <name>");
hello.add("name", "World");
System.out.println(hello.render());

prints out:

"Hello World"

I don't know if there is anything equal, but you can do:

String s = "$who likes $what";
s.replace("$who", "tim").replace("$what", "kung pao");

And you will get the same result.

Chunk templates ( http://www.x5dev.com/chunk ) make this kind of thing pretty easy:

Chunk c = new Chunk();
c.append("{$who} likes {$what}");
c.set("who", "tim");
c.set("what", "kung pao");
String output = c.toString();

Or if you have a Map<String,String> already:

Chunk c = new Chunk();
c.append("{$who} likes {$what}");
Map<String,String> tagValues = getTagValues();
c.setMultiple(tagValues);
c.render(System.out);

Chunk also makes it easy to load templates from a file or a group of files, and supports looping, branching, and presentation filters.

Answer 4

String s = String.format("%s likes %s", "tim", "kung pao");

or

System.out.printf("%s likes %s", "tim", "kung pao");

you can easily do the templating with this too.

String s = "%s likes %s";
String.format(s, "tim", "kung pao");

Answer 5

I think you can use String.format to achieve this.
