[stringtemplate-interest] A few notes on StringTemplate v4 beta

[Matthieu Wipliez]

Hi Terence,

it's great to see this beta released!
I have been using the early adopter version for 9 months now, and tried the beta 
version yesterday.
With my templates this version is definitely faster!

However, I believe I have found a bug in this release with "elseif" 
conditionally-included templates.
The test case below fails with "fail2" but I would expect it to work:

@Test public void testElseIf2() throws Exception {
        String template = 
"<if(x)>fail1<elseif(y)>fail2<elseif(z)>works<else>fail3<endif>";
        ST st = new ST(template);
        st.add("z", "2DF3DF");
        String expected = "works";
        String result = st.render();
        assertEquals(expected, result);
    }


Other differences I have noticed with the early adopter version is that it seems 
that $it$ is not propagated *at all* anymore.
For instance I needed to replace
  $value : {[$it$]}$ 
with
  $value : {v | [$v$]}$

Is this intended?
You mention in the differences between v3 and v4 both "no "it" iteration value" 
and "default attr 'it' only set if no arg in {...}.".
So... which one is it? Is "it" allowed?

Also, I have tried the TestCoreBasics unit test, and on Windows a couple of 
tests fail (namely testInclude and testFalseCondWithFormalArgs) because of the 
difference between the Unix and Windows EOL convention: expected is "x\ny" and 
result is "x\r\ny".

Cheers
Matthieu
