Adding japid to benchmark

[PerfectCarl]

I want to add japid to the template framework benchmark

So I need to code a simple class that would instanciate a japid template engine, give a collection of Item as an input parameter and execute the thing.

Here's an example of code for another template engine

        // Some template engine specific code
        Properties p = new Properties();
        p.put("log.enabled", false);
        p.put("feature.smart_escape.enabled", false);
        p.put("feature.transform.enabled", false);

        // here we go 
        engine = new RythmEngine(p);

        // Parameters
        String tmpl = "path/to/my/template.rythm.html" ; 
        List<Stock> items = ...
        OutputStream o1 = ... 

        // Get the template output in the output stream o1  
        engine.render(o1, tmpl, items);
        o1.close();

Could you help me writing the code for japid ?

Assuming you have a folder named "plainjapid" in your application root and your template is:

"plainjapid/japidviews/my/view.html"

final String UNI = "universe";

JapidRenderer.init(OpMode.prod, "plainjapid", 1, null);

for (...) {

String r = JapidRenderer.renderWith("my.view", UNI);

System.out.println(r); }

I assumed you were testing against Japid and not Japid42, which is for integration with Play2.

Thanks for your help, it is almost working. But I have an error :

Here's my code :

        JapidRenderer.init(OpMode.dev, "templates", 1, null);
        output = JapidRenderer.renderWith(template, UNI);

And here's my template :

`args String test 

TEST

By the way, it there any way to have a look at the generated classes ? Where are the generated source file generated ?

[PerfectCarl]

Okay, my bad. I was using the wrong template.

[branaway]

The generated Java classes are next to the Japid scripts.

Use prod mode when you do the benchmarking.

[PerfectCarl]

So I need to run the code once in dev mode to generate the file, and then in prod to do the benchmark. Is that right ?

[branaway]

It's not needed. It will get compiled when the Japid engine is initialized.

When I use prod mode, I get this error :

Should my template be stored in different folder for production mode ?

[PerfectCarl]

When I get the produced string I get the following lines at start :

[JapidRender]: All java files are up to date.

[JapidRender]: All java files are up to date.

[JapidRender]: All java files are up to date.

[JapidRender]: All java files are up to date.

[JapidRender]: All java files are up to date.

[JapidRender]: All java files are up to date.

Is this because I am in dev mode ?

[branaway]

To disable the verbose output in dev mode:

cn.bran.japid.util.JapidFlags.verbose = false;

Hey,

I'm done with porting japid to the benchmark.

I still have issue with the production mode hint that you gave me.

That being said, would you be kind enough to have a look at my use of japid. Here's the java file invoking the engine and here's the template

Do you see any thing that can hinder the performance of japid ? The rendering is executed many times : maybe there is a way to keep the compiled template in memory (if that's not the case already).

[branaway]

I'll take a look at the prod issue in a bit.

The "open for" loop in the template comes with performance cost if you try to avoid any overhead.

Using generic for loop will help.

@int _index = 1; @boolean _isOdd = true; @for (Stock item: items) { ... ... @ _index++; _isOdd = !_isOdd; @}

The render class should have been cached already. So nothing to tweak there.

But there would be no performance if it runs in dev mode. Stay tuned for my diagnose.

[branaway]

Thanks for reporting I actually have found an obvious bug. Please try version 0.9.31 to get the fix.

[PerfectCarl]

Great. Oh and, not that I expect it would be a surprise for you, but japid's performance are easily among the best. Le 18 oct. 2013 10:59, "branaway" notifications@github.com a écrit :

It works great. Though, I have the following error

[Japid] [error] could not find the apply() with japid class: null

Is this a warning ?

[branaway]

The message was misleading. Fixed it in version 0.9.32 plus an important bug fix in tracking the source code of Japid classes. Please upgrade.
