node-jinjs's Introduction

JinJS

As stated on Jinja's home page, "Jinja Is Beautiful"

{% extends "layout.html" %}
{% block body %}
  <ul>
  {% for user in users %}
    <li><a href="{{ user.url }}">{{ user.username }}</a></li>
  {% endfor %}
  </ul>
{% endblock %}

JinJS is the native port of Jinja to the world of NodeJS. Just like Jinja, it aims to transform template documents to native javascript code to maximize execution speed.

node-jinjs's Issues

proper way to do {% extends 'some.template' %}

I can't seem to get your extends syntax to work.

require("jinjs").registerExtension(".template");
var base_template = require("./base");

var the_template = require("./test");

var result = the_template.render({});

test.template:

{% extends "base.template" %}

{% block body %}
  Testing 123
{% endblock %}

base.template:

<head>
<title>Hello there!</title>
</head>
<body>
{% block body %}
{% endblock %}
</body>
</head>

This gives me:

Error: Cannot find module 'base.template'

just js would be nice

I really want to provide a solid django-inspired template engine for the Express users, and this certainly looks like a good start. however that weird language you're using is going to be a big barrier for contribution. I definitely recommend just writing js in js so people like myself who actually know the language can help tune/fix things

Implement loop control {% break %} and {% continue %}

This should not be too hard.

Redo the general parser in JinJS

The current parser is a mess.

Implement the test with "is"

Jinja has a lovely testing facility : {% toto is divisibleby 3 %}. see : http://jinja.pocoo.org/docs/templates/#list-of-builtin-tests

Also ; pass this as the context

Implement the following :

callable (function)
defined
divisibleby
escaped
even
--iterable-- can't implement this in JS ; everything is iterable (except maybe numbers and dates)
lower
null (none)
number
odd
sameas
array
string
undefined
upper

And the operators is and is not in the expression grammar.

request stay awaiting response with jinjs attached

Hi, thanks for this project.
I tried to use it in a simple project to test the template inheritance (because express lacks of this feature).

this is my app.js: https://gist.github.com/1222305

but I dont get nothing, sever stay awaiting response.

What do you say? and thanks in advance.

Template inclusion and browserify

The fact that __get_template__ is used to get the templates confuses browserify, which requires explicit calls to require.

This should change to not have to manually load the template base elsewhere.

How to extract used variables from a template?

The Python implementation has a way to extract the variables used in the template, is it possible to do the same with jinjs?

line statements

hi, are line statements be supported in future releases ?

Thanks

npm istall jinjs 0.3.6 bug

require("jinjs")
Error: Cannot find module 'jinjs'

$ node -v
v0.6.9
$ npm -v
1.1.0-2

P.S. jinjs v 0.3.5 works fine

Remove the eval() calls in the generated template.

Eval() is evil !

And filters and functions won't change a lot when in a browserify-ed environment.

var
{% for f in filters %}
{{ f }} = filters_{{ f }},
{% endfor %}

or something like that.

Filters broken?

I'm trying to use filters in an Exprss.js-application, but it isn't working for me, and I can't quite figure out what's wrong.

Given this template :

{{ foo }}
{{ foo | capitalize }}
{{ foo | $capitalize }}
{{ foo | Capitalize }}
{{ foo | nosuchfilter }}

With {foo: "bar this"}, I get the following output:

bar this
0
0
0
0

(From using Jinja, I would expect at least one of the above to be foo this.)

I'm running Node.js v0.6.19 and the relevant parts of npm ls are as follow:

├─┬ [email protected]
│ ├─┬ [email protected]
│ │ └── [email protected]
│ ├── [email protected]
│ ├── [email protected]
│ └── [email protected]
├─┬ [email protected]
│ └─┬ [email protected]
│ └── [email protected]

The server I'm using looks like this:

var express = require('express'),
    app = express.createServer();

app.set("view options", { layout: false });

app.get('/*', function (req, res) {
    res.render('test.jinjs', {foo: "bar this"});
});

app.listen(3000);

As I can't generally see other people complain about this fairly obvious bug, my working assumption is that I've missed something important. Any pointers?

use jinjs with express, errors occured

who can explain that?

Jinjs: 0.3.5

Node: 0.6.7
OS: Debian

"news" in for-loop variable name gives TypeError

Following situation:

test.tpl

{% for i in news %}
{{ i.title }}
{% endfor %}

test.js

require("jinjs").registerExtension(".tpl");
var main_template = require("./test");
var context = { news : [{title: "test one"}, {title: "test two"}]};
console.log(main_template.render(context));

Then, node test.js gives me the following error:

var _fref = new $$.s || [], _prev_loop = $$.loop, _prev_key = $$['i'], _prev_value = null, k = null, v = null, i = 0, l = 0, x = null, last_v = null, last_k = null;
            ^

TypeError: $$.s is not a constructor

Changing to `foo` and the error goes away

If I replace news with foo or bnews, then the error doesn't occur anymore.

However, the error still occurs for words like newsarticles.

this error pops up 3-4 times, and after some refreshes, it magically shows the template perfectly.
Any idea what might be going wrong?

call() fails with imported macros.

ReferenceError: <macro_name> is not defined

implement raw

Hi, as I see {% raw %} is not implemented, I tried to use angular js which uses {{ }} as well so I realized that raw is not there :/

Any workaround for that?

ability to add filters

Hello!

Is it possible to add filters to the environment/context?
Or if it is possible, would you document it please?

Implement {% autoescape %} and an escaping policy

So far, nothing is escaped.

{% autoescape on %} should have escaping done all the time. {% endautoescape %}

Create the |e filter and the |ejs or |escapejs filter for javascript code.

With express you get - Maximum call stack size exceeded when running

Steps to reproduce

cd test/express
coco app.co

Expected results

All tests honored

Actual results

4 honored and 2 broken.

The jinja templates in Express can use its own include facility
test
"Hello World." == "RangeError: Maximum call stack size exceeded"

Environment

Ubuntu 11.04
node v0.6.0
jinjs 0.3.3

for objElement in obj is not compatible with some objects which are not iteratable but have forEach method

I am currently using JS Generator, which produced objects which are not iteratable, but have forEach as the method. My current workaound is to use toArray before rendering. However, it would be great if we can change the internal implementation to support forEach method.

Pass ctx as this to filters and tests

They may be interested in dealing with the context, so pass it to them by .call (__ctx__, ...) to not disturb their signature.

Use vm.* to load the templates when used with node.

let instead of set? typo?

Just wondering, you have let tag instead of set tag, is it a typo?

For instance this:

{% set foo = 'something' %}
foo is {{ foo }}

throws Error: Unexpected tag : 'set'

this works fine:

{% let foo = 'something' %}
foo is {{ foo }}

jinjs not compatible with express 3.x

It seems the entire template engine system has been overhauled in express 3.x:

template engine compliance from engine.compile(str, options) => Function to engine.__express(filename, options, callback)

https://github.com/visionmedia/express/wiki/Migrating-from-2.x-to-3.x

npm install is broken.

I tested git version vs npm install.

The two issues i noticed when using npm install

Cannot require without modifying package.json. I have posted this bug in another ticket.

TypeError: object is not a function
    at ExpressEnvironment.CALL_NON_FUNCTION (native)

This happens while requesting a simple page.

If i clone jinjs from git, and install its dependencies via npm the parser works correctly.

Change the undefined var printing policy

Allow for greater control :

throw Exception
print ""
catch Exception when using/calling stuff of undefined variables.

Only will work in the {{ }} statement, and will be defined at the environment level.

Feature additions

Hi, I was looking at Kiwi template engine and seems to have some cool features that would be very cool to have in JinJS. Some of those features are empty clause and ifblock tag

Project dead?

Implement the missing filters

Implement the following filters as specified here : http://jinja.pocoo.org/docs/templates/#list-of-builtin-filters

batch
center
dictsort
escape
escapejs
forceescape
format
groupby
indent
pprint
random
replace
safe
slice
sort
striptags
sum
title
truncate
upper
urlize
wordwrap
xmlattr

directory layout and/or package.json wrong possibly?

While attempting to use the jinjs package for the first time via npm install

npm install jinjs

coffee test.coffee 
Error: Cannot find module 'jinjs'
    at Function._resolveFilename (module.js:334:11)
    at Function._load (module.js:279:25)
    at Module.require (module.js:357:17)
    at require (module.js:373:17)

   <snip>Im paranoid about file paths :)</snip>

# contents of test.coffee
jinjs = require "jinjs"

I was able to get it working by simply creating symlink to tball/lib

ln -s tball/lib/ lib

express running, modified template cannot be rendered rightly

when express server is running, I modify my template. Then access the page, the errors occurred:

500 TypeError: Cannot set property '/home/jock/apps/huodongtong/app/views/layout/form_layout.html' of undefined
at /home/jock/node_modules/jinjs/lib/environment.js:159:38

at Controller.render (/home/jock/node_modules/locomotive/lib/locomotive/controller.js:98:14)

But, when I restart the server, all is right again.

what's the problem? Jinjs cached something or not?

Another question, can Jinjs can persist the compiled templates into physical files?

Implement named arguments function calling

This can't be implemented on functions that comme from javascript.

However, it would be possible for macros, filters, and tests, to have an optional signature attribute with a list of arguments and a default_args to fill up the missing attributes when not specified.

Exemple ;

exports.dictsort = (value, case_sensitive ? false, _by ? 'value') ->
   ...
exports.dictsort.signature = ["value", "case_sensitive", "by"]
exports.dictsort.default_args = ["", false, "value"]

if a call is parsed and "by" is specified, then case_sensitive still gets sent false.

{% filter <filter> %} {% endfilter %} is not supported?

I tried this from examples but I got Unexpected tag : 'filter' error, filter is not supported as tag?

{% filter upper %}
    This text becomes uppercase
{% endfilter %}
