Perl:Javascript :: V8模板-来自perl [英] Perl: Javascript::V8 templates - from the perl
问题描述
正在寻找诸如HTML :: Mason(或Mason)之类的模板引擎,因此将源组件编译"为perl代码的是什么,而不是perl-code会将组件"编译"为JavaScript代码,并在使用Javascript运行/执行它们之后:: V8 perl模块.
Looking for template engine like HTML::Mason (or Mason), so what "compiles" source components into perl code, but instead of perl-code will "compile" components into JavaScript code and after run/execute them with Javascript::V8 perl module.
动机:寻找安全模板语言的解决方案,可以编辑用户而又不影响服务器安全性的. JavaScript是全功能语言,因此使用它可能比TT或类似的迷你语言"更好/更快.对我而言,最好的方法是对Mason进行扩展(重写),以将其编译为Joose/JavaScript而不是Moose/Perl. ;)
Motivation: Looking for solution for safe template language, what can edit users without compromising the server security. JavaScript is full featured language so using it is probably better/faster than some "mini languages" like TT or similar. The best for me would be an extension (rewrite) of Mason for compiling into Joose/JavaScript instead of Moose/Perl. ;)
是的,要使用Javascript :: V8在perl中执行此操作,因为可以通过这种方式以非常安全的方式通过Javascript :: V8 $ context-> bind_function获得所有perl的功能.
And yes, want do this from perl with Javascript::V8 because this way is possible having all perl's power available via Javascript::V8 $context->bind_function in very safe way.
问题:
- 有人知道吗? (在CPAN中什么都没找到)...
在梅森,您可以编写例如
in Mason you can write for example
% #perl version
% my(@list) = qw(Jane John Doe);
<ul>
% foreach my $item (@list) {
<li><% uc($item) %></li>
% }
</ul>
很高兴有可能用JS编写上述代码,例如:
would be nice to have possibility write the above in JS, like:
% //javascript version
% var list = ["Jane", "John", "Doe"];
<ul>
% for(var i in list) {
<li><% perl_uc($list[i]) %></li>
<!-- the "perl_uc" is the real perl uc() what is binded
with Javascript::V8::bind_function(perl_uc => sub { return uc(@_) }
-->
% }
</ul>
应将以上源代码编译"为JavaScript(Joose),并使用Javascript :: V8执行. (就像在Mason中一样-源代码被编译成perl/Moose对象并用perl执行)...
The above source should be "compiled" into JavaScript (Joose), and executed with Javascript::V8. (like in Mason - the source is compiled into perl/Moose object and executed with perl)...
如您所见,for(var i in list)
是用纯JS编写的,而不是用迷你语言"写的...
As you can see, the for(var i in list)
is written in pure JS, and not in "mini-language"…

这是 EJS :: Template .
它完全符合您的要求-将模板编译为JS并使用V8
(甚至是JE
)引擎进行评估.不幸的是,还没有 Javascript :: Duktape 引擎支持(至今).
Here is the EJS::Template.
It does exactly for what you asked - compiles the templates into JS and using V8
(or even JE
) engines for evaluate. Unfortunately, has no Javascript::Duktape engine support (yet).
此外,这也是如何在Duktape引擎中使用 great @ysth的答案中的Jemplate
(服务器端)的方法.
Also, here is a snipet how to use the Jemplate
(server-side) from the great @ysth's answer with the Duktape engine.
use strict;
use warnings;
use Jemplate;
use JavaScript::Duktape;
# can omit these steps - see bellow
# Get the lite runtime js-source without the unnecessary AJAX (we are server side)
my $jemp_runtime = Jemplate::runtime_source_code('lite');
# The Template::Toolkit template
my $template = q{
[%- FOREACH pope IN perlmonks -%]
pope: [% pope.name %] = [% pope.experience %]
[% END -%]
};
# compile the Template source using Jemplate and name it
my $jemp_template = Jemplate->compile_template_content($template, 'monkstemplate');
# the data
my $data = {
'perlmonks' => [
{ 'name' => 'vroom', 'experience' => '1007479', },
{ 'name' => 'BrowserUk','experience' => '167247', },
{ 'name' => 'Corion', 'experience' => '133975', },
{ 'name' => 'ikegami', 'experience' => '128977', }
]
};
# init
my $js = JavaScript::Duktape->new();
$js->set( 'write' => sub { print $_[0]; } );
$js->eval($jemp_runtime); # eval the runtime code
$js->eval($jemp_template); # the Template code compiled into JS
$js->set("monkdata", $data);# bind the data
# finally eval the template processing code
$js->eval(q!
write(
Jemplate.process('monkstemplate', monkdata)
);
!);
产生
pope: vroom = 1007479
pope: BrowserUk = 167247
pope: Corion = 133975
pope: ikegami = 128977
您可以通过使用jemplate
命令预先编译模板来忽略所有Jemplate调用,例如:
You can omit all Jemplate calls, by compiling the templates beforehand using the jemplate
command, like:
jemplate --runtime=lite --compile /path/to/templates > jemplate_source.js
然后只需加载jemplate_source.js
并将其评估到JS引擎中即可.
And just load the jemplate_source.js
and eval it in the JS engine.
仅作说明:在我的笔记本上,使用原始的 TemplateToolkit ,我得到了10k/sec.上面的Jemplate/Duktape仅5k/sec.
Just for note: On my noteboook, using the original TemplateToolkit i got 10k/sec. The above Jemplate/Duktape only 5k/sec.
我的原始答案:
这里是 Shotenjin 源自Tenjin模板系统. (perl Tenjin在这里.
Here is Shotenjin what is derived from a Tenjin template system. (the perl Tenjin is here.
Shotenjin是基于joose的,因此可以通过使用Javascript :: V8从perl中使用Shotenjin进行一些额外的工作.但是,对于您的外观来说仍然不完美.
Shotenjin is joose based, so with some plus work will be possible use Shotenjin from a perl with Javascript::V8. But it is still not exacly for what youre looking.
对于您想要的东西,已经完成了-不幸的是,对于RUBY. https://github.com/elado/isotope
For what you're looking is already done - unfortunately, for the RUBY. https://github.com/elado/isotope
刚刚发现:这是 Template :: JavaScript TT编译成的内容JS,并通过v8服务器端执行...
Just discovered: here is Template::JavaScript what is TT compiled into JS and executed with v8 server side...
