Hello sir, please take a look at the following issue, let me know what you think is the best - to fix it on ect side, or on co-views side, or maybe on both? Thank you.

Can you change package.json, so coffee-script depends on the latest coffee-script

coffee-script: ">=1.5.0"

because after require ect

ect = require 'ect'

coffee interpreter acts like 1.5.0 and does not work with my scripts because they made for version 1.6.2 (some sugar with brackets)

Vadim,

I there a way to leave a comment in a .ect file? I cant find any documentation about that.

Example:

<% /* my comment */ %>
or
<% // my comment %>

Hi Vadim,

Is there a way to put default block content and if child has this block then it will overrule it?

Example:
layout.ect

<% if blockExists('menu1') : %>
<% content 'menu1' %>
<% else : %>
<ul class="menu_default"><li>item</li></ul>
<% end %>

child.ect

<% extend layout.ect %>
<% block 'menu1' %>
<ul class="menu1"><li>item</li></ul>
<% end %>

Could you please explain the advantages of using ect other than its performance. PRos and cons of each language in general. It's the utmost necessity if you want to increase the user base. MOre detailed the analysis is, better. Also sorry for my ignorance, but why performance is important? Arent they all get compiled to html at the end. Does performance make any difference to the end user(a web site visitor).

Partials are nice but it is difficult to pass in a huge block of html to a partial.

Say we have this template 'test.ect'

<div class="houses">
   <% content %>
</div>

then it would be cool to do something like:

<% include "test.ect" : %>
   <div>A</div>
<% end %>
<% include "test.ect" : %>
  <div>B</div>
<% end %>

It's interesting to see some comparison with yate - would it be still the fastest template engine or yate Please add comparison with yate will be faster?

In a view I have the following code

[[- JSON.stringify @value ]]
[[- field for field, val of @value ]]

that results in the output

name,id,qty,unit,notes,role
{"name":"whatever","id":"234"} 

but if I try to access any field with

[[- @value.name ]]

it returns

TypeError: Cannot read property 'name' of undefined in ...

does anyone know what could be going wrong?
(I never come across this kind of error before in my 5 months of using ECT)

Does something like this exist or any interest in adding such a feature?

I get "unexpected indent" errors for an if/else if/else statement. Something like this:

<% if 'one thing': %>
foo
<% else if 'other': %>
bar
<% else: %>
baz
<% end %>

Should that work?

I want to convey how awesome this is. Difficult without a demo! :)

Can anyone else confirm this?

app.locals({
name: 'joe'
})

<%- name %>

This should render 'joe', however it says 'name is undefined'.

I tried Swig as an alternative, and Swig appears to work fine.

Is there simple "ECT" way to escape the user entered text and add breaks?

I use MongoDB witch has JSON data and it has \n witch i want to translate to breaks.

<%= @company.description.replace(/\n/g, '<br>') %>

This code will escape <br> tags also.

I am making making an Ect renderer plugin for DocPad, a Node static website generator.

DocPad has it's own implementation of templates, but blocks and partials aren't implemented into core (AFAIK).

I need to know if Ect requires the template, partials and blocks folder or if it's optional. I'd like to implement it but if it's not necessary I'll leave it off the initial release.

Thanks!

I'm trying access the global scope from this function:

// js
<% write = (input) -> %>
    <div class="translated"><%- @translate input %></div>
<% end %>

<%- write 'hello' %>

// data
{
    translate: function(input){ return: 'hello world' }
}

but I get this Error:

Cannot call method 'translate' of undefined in page on line 2

Hi i have simple code that i will render:
150 x FOO.

When i render it with Node.js template (ECT) the response time is: 1855ms
With PHP response time is: 24ms

ECT code:

<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
...

PHP code:

<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
...

All are no cached.
And how bigger the count the slower becomes NodeJS (ECT)

Is there something that i miss?

Hey guys-

So I serve a JS site using rails (I love my asset pipeline), and am looking to switch over from eco, but this workflow is quite dependent on the https://github.com/sstephenson/ruby-eco gem — which provides the hooks necessary for sprockets, etc...for out of the box compilation.

Does an equivalent gem (or process) exist for ect? Just curious if anyone else has done this process before I jump down a rabbit hole that may be deeper than I want it to be. :)

Hi, kudos for being the fastest so far!

Is there any way to hook up an HTML preprocessor (Jade comes to mind, but others might do, I'm sorta fond of Slim as well)?

Thanks

Hi,
i keep getting this error when trying to setup etc with express

Error: callback function required

on

app.engine('.ect', ectRenderer.render);

Node v 0.10.24 Express v 3.4.7

С использованием Marionnete JS появилась необходимость писать шаблоны внутри HTML таким образом

<script id="feature-template" type="text/html">
                    <div class="item">
                        <div class="name"><%= name %></div>
                    </div>
                </script>

Но шаблонизатор ECT пытается показать эти переменные тоже. Можно ли как-нибудь указать зону, что бы она не обрабатывалась, а выводилась как есть?

Приведу пример

<% include 'partials/showcase', [ '001', '002', '003' ] %>

partials/showcase.ect:

<% for image in @context : %>
    <a href="/img/<% image %>.jpg"><img src="/img/<% image %>_tn.jpg" /></a>
<% end %>

Думаю, кейс понятен. Вопрос в том как обратиться напрямую к переданному контексту. Понятно, что можно передавать { items: [ ... ] }, а потом получать с помощью for image in @items, но не очень красиво.

The following code errors:

ect = require 'ect'
fs  = require 'fs'

ect = ect {}

fs.writeFileSync 'test.ect', '<%- @test do => %>foo<% end %>'

console.log ect.render 'test.ect', test: (str) ->
    "#{str}bar"

fs.unlinkSync 'test.ect'

The expected result should be 'foobar' instead it errors with the following message SyntaxError: missing ) in test.ect.

Works fine on eco and is the only thing stopping me from using this library as a large majority of our views do this to pass HTML to view helpers.

Great library, thanks!

is there a GRUNT precompiler available??

В директории с шаблонами есть файл select.ect, используя пример из документации

var ECT = require('ect');
var renderer = ECT({ root : __dirname + '/views', ext : '.ect' });
renderer.render('select', {}, function (error, html) {
    ...
});

получаем ошибку, что не найден se.ect. :-)
Поправьте, пожалуйста, создание регулярки в функции TemplateContext.prototype.load хотя бы на что-нибудь типа:

var extExp = new RegExp(ect.options.ext.replace('.','\\.') + '$');

Спасибо!

from the official site:

<% if @links?.length : %>
    <ul>
        <% for link in @links : %>
            <%- linkHelper link %>
        <% end %>
    </ul>
<% else : %>
    <p>List is empty</p>
<% end %>

What is the purpose of using a colon at the end? It's not a CoffeeScript syntax.
And will it be removed in the future?

Делаю многоязыковое приложение.
Приходится на любой вызов рендеринга шаблона передавать переменную, содержащую язык.
Есть ли возможность для каждого HTTP-запроса создавать новый экземпляр ECT с переменными по умолчанию? И ещё, не накладно ли это по ресурсам?

There are command line tools for use iwth node/npm bundled with ECT but they only allow to compile to a template function not directly to a html file. It would be nice to offer support for that.

Something I just saw mentioned about the new version of jade is the support of appending data to template blocks instead of overwriting them (http://stackoverflow.com/a/14377282/339872)

It would be useful.

Otherwise, a great engine - html based, extendable templates, support for partials & blocks - all that you need :)

Hi,

I have a file structure like this:

.
├── index.html
└── layouts
    ├── default.html
    └── partials
        └── metas.html

Template root is set to the folder containing index.html and ext is set to .html.

index.html extends layouts/default.html and layouts/default.html includes partials/metas.html.

Is it by design, that I have to write all my includes and extends relative to the template root folder? Like <% include 'layouts/partials/metas' %> in layouts/default.html. At first I thought it should be just <% include 'partials/metas' %> because default.html is already in the layouts folder. It would be cool to use relative include paths.

},

Ошибка Uncaught TypeError: Cannot call method 'compile' of undefined in /assets/templates/index.ect

I'm trying to write a brunch plugin (see http://brunch.io/) to replace my usage of the eco brunch plugin. See here for the implementation of eco-bruch: https://github.com/brunch/eco-brunch/blob/master/lib/index.js

(Mainly so that I can use <% include 'snippet.eco' %> client-side, but I suppose that would require further work.)

Basically I want to mimic this by compiling to a function render(obj) {return 'some text';} style function that can just be converted to code with .toString() and then that gets bundled up with a bunch of other things and sent through to the browser.

I can't find an easy way to achieve that. Am I missing something?

I'm not 100% sure on this one yet. If it happens again I'll see if I can fix it.

Is there a way to minify HTML outputs?
Dont see anything about this in documentation.

If I do:

res.locals.user = { name: 'Tom' }
res.render('page')

And in page.ect I do:

<% include 'user' %>

I'd like user.ect to have access to @user. Currently I must pass user explicitly:

<% include 'user', { user: @user } %>

This can get tedious for complex page. Is there a better way?

In our app in some very rare cases there is need to directly access db from templates, this could only be done via async query and it would be nice if ECT could support it. i.e such code

<% do @getCount (countFromDB) -> : %>
  <span>The count is <%= countFromDB %></span>
<% end %>

ECT is an excellent template language. I like the way it support the client side templates using the middleware compilation. Is there any way to use the client side templates with pre compiled templates. I don't have a running node middleware on my hosting server. I want to precompile all the templates on my dev server and include the result js directly in my client app. Is there any way to achieve this?

Thanks

I love ECT and coffeescript with beautiful syntax.
and We need some supplement like this:
if the templates and the scripts are in the same page, how to render?

i tred to used this tempate engine with expressjs framework.
if i use temaplet with out layout it works. E.g

<div>Hello, World!</div>

if i use with layout it thorw exception. E.g

<% extend 'layout' %>
<div>Hello, World!</div>

Here is error:
Error: Failed to load template D:\Mirodil\Dropbox\justdoit\bigshop\views
D:\Mirodil\Dropbox\justdoit\bigshop\views\index.ect
at read (C:\Program Files\nodejs\node_modules\ect\lib\ect.js:245:13)

The problem in the rendering, expressjs pass full path of themplate file and in the tempate it render without any error if in this tempate does not contanins any referens to other templates.

There is an issue when i try to add jquery file.

Example:

layout.ect

<script src="/js/assets/jquery-1.9.1.min.js"></script>

and in my console is see:

GET /js/assets/jquery.min.map 404 39ms - 56b

in jquery-1.9.1.min.js file there is a declaration on line 2:
//@ sourceMappingURL=jquery.min.map

With Jade template engine i didnt get any 404 errors.
How it come? Do i miss something?

Мне все же никак не дает покоя факт синхронной загрузки данных на клиенте. Все таки подвисание браузера пусть даже на 100-200 милисекунд это плохо. А если мне надо загрузить сразу 10-20 шаблонов? А если сервер недоступен или не справляется с нагрузкой, так браузер вообще может секунд 5-10 не реагировать на действия пользователя (передвижение курсора, клики).
http://xmlhttprequest.ru/ вот тут есть пример того, как синхронный запрос блокирует браузер на 3 секунды.
Я написал функцию readFileAsync. Функция предельно проста, она принимает 2 аргумента, первый - файл, второй - колбэк. В колбэк передается единственный параметр - ответ от сервера. Я надеюсь вам не сложно будет заменить синхронную загрузку на асинсхонную. Если вдруг нужна будет помощь, я вам помогу.

readFileAsync = function (file, callback) {
    var AJAX;
    try {
        AJAX = new ActiveXObject("Msxml2.XMLHTTP");
    } catch (e) {
    try {
        AJAX = new ActiveXObject("Microsoft.XMLHTTP");
    } catch (E) {
        AJAX = false;
    }
    }
    if (!AJAX && typeof XMLHttpRequest!='undefined') {
    AJAX = new XMLHttpRequest();
    }
    if (AJAX) {
        AJAX.open('GET', file, true);
        AJAX.send(null);
        AJAX.onreadystatechange = function() {
          if (AJAX.readyState == 4&&AJAX.status == 200) {
                if(typeof callback=="function")callback(AJAX.responseText);
            }
            else if(AJAX.status !== 0 && (AJAX.status < 200 || AJAX.status > 399)) {
                throw new Error ('Failed to load template ' + file);
            }
        }
    } else {
        throw new Error ('Failed to load template ' + file);
    }
}

Пример вызова

readFileAsync("/view/template.html",
function(data){
compiled=eval(data)
})

Вадим, я надеюсь на вас, правда)

Hi,

congrats for your nice work!

CS syntax in template sounds promising however, on client-side including full CS compiler (39k when gzipped) seems not good enough especially in mobile env.

Is there some way to distribute pre-compiled template to client?

I tried to do <%-(@opt_time_groups[key].name?=123)%> or <%-(@opt_time_groups[key].name || 123)%> but have got no success and "TypeError: Cannot read property 'name' of undefined" error. Could you tell me please, how do I intended to do that thing in ECT?

Full code is:

<%for key of @opt_time_groups.concat([1..3]) : %>
  <tr>
    <td>
      <input 
        type="text" 
        name="opt_time_groups[<%-key%>][name]" 
        value="<%-@opt_time_groups[key].name || 123%>"
        />
    </td>
  </tr>
<%end%>

Obviously, it's my mistake. Not an issue. The solution is:

<%-if @opt_time_groups[key] then @opt_time_groups[key].name else 123%>

"locals" is the default variable passed to render engine by express app. after few hours or researching, I've found it's possible to access part of "locals" data in "_locals" variable.

here is the example:
//setting locals data
app.use(function(req, res, next){
res.locals.messages = req.flash();
res.locals.user = req.user;
console.dir(res.locals);
next();
});
//accessing it
<% if @_locals and @_locals['messages'] : %>
<% if @_locals.messages['error'] : %>

Is this template template engine works with Expressjs?

I'm using ect with express.
Is it possible to access req.session inside a template?
<%- req.session.user %> or <%- @req.session.user %>

can there be a slim/jade like syntax support instead of html

Вадим, можете пожалуйста сделать то же самое, что вы сделали, но без CoffeeScript, а на чистом JS, как, к примеру, в шаблонизаторе EJS. Я сейчас его использую, но я сравнил скорость ECT и EJS, в некоторых ситуациях ECT выигрывает по производительности в 5 раз. Но во первых не хочется учить новый синтаксис, а во вторых не хочется переписывать шаблоны. Было бы просто замечательно если бы вы сделали это.

Я уже понял что то про MIddleWare, но не совсем понятно как его реализовать с express.
В данный момент у меня вот такая конструкция

app.use(ECT.compiler({ root: '/view' }))
app.all('/*',function(request,response){
    new rootController(request,response);
}); 

Но запрос /vew/template.html все равно берет на себя последняя конструкция.
Пожалуйста, помогите правильно сделать?
