hamlpy's Introduction

HamlPy

HamlPy (pronounced "haml pie") is a tool for Django developers who want to use a Haml like syntax for their templates. HamlPy is not a template engine in itself but simply a compiler which will convert HamlPy files into templates that Django can understand.

But wait, what is Haml? Haml is an incredible template engine written in Ruby used a lot in the Rails community. You can read more about it here.

Installing

Stable release

The latest stable version of HamlPy can be installed using setuptools easy_install hamlpy or pip (pip install hamlpy)

Development

The latest development version can be installed directly from GitHub:

pip install https://github.com/jessemiller/HamlPy/tarball/master

Syntax

Almost all of the XHTML syntax of Haml is preserved.

#profile
	.left.column
		#date 2010/02/18
		#address Toronto, ON
	.right.column
		#bio Jesse Miller

turns into..

<div id='profile'>
	<div class='left column'>
		<div id='date'>2010/02/18</div>
		<div id='address'>Toronto, ON</div>
	</div>
	<div class='right column'>
		<div id='bio'>Jesse Miller</div>
	</div>
</div>

The main difference is instead of interpreting Ruby, or even Python we instead can create Django Tags and Variables

%ul#athletes
	- for athlete in athlete_list
		%li.athlete{'id': 'athlete_{{ athlete.pk }}'}= athlete.name

turns into..

<ul id='athletes'>
	{% for athlete in athlete_list %}
		<li class='athlete' id='athlete_{{ athlete.pk }}'>{{ athlete.name }}</li>
	{% endfor %}
</ul>

Usage

Option 1: Template loader

The template loader was originally written by Chris Hartjes under the name 'djaml'. This project has now been merged into the HamlPy codebase.

Add the HamlPy template loaders to the Django template loaders:

TEMPLATE_LOADERS = (
    'hamlpy.template.loaders.HamlPyFilesystemLoader',
    'hamlpy.template.loaders.HamlPyAppDirectoriesLoader',   
    ...
)

If you don't put the HamlPy template loader first, then the standard Django template loaders will try to process it first. Make sure your templates have a .haml or .hamlpy extension, and put them wherever you've told Django to expect to find templates (TEMPLATE_DIRS).

Template caching

For caching, just add django.template.loaders.cached.Loader to your TEMPLATE_LOADERS:

TEMPLATE_LOADERS = (
    ('django.template.loaders.cached.Loader', (
	    'hamlpy.template.loaders.HamlPyFilesystemLoader',
	    'hamlpy.template.loaders.HamlPyAppDirectoriesLoader',
	    ...
    )),   
)

Settings

Following values in Django settings affect haml processing:

HAMLPY_ATTR_WRAPPER -- The character that should wrap element attributes. This defaults to ' (an apostrophe).

Option 2: Watcher

HamlPy can also be used as a stand-alone program. There is a script which will watch for changed hamlpy extensions and regenerate the html as they are edited:

    usage: hamlpy-watcher [-h] [-v] [-i EXT [EXT ...]] [-ext EXT] [-r S]
                        [--tag TAG] [--attr-wrapper {",'}]
                        input_dir [output_dir]

    positional arguments:
    input_dir             Folder to watch
    output_dir            Destination folder

    optional arguments:
    -h, --help            show this help message and exit
    -v, --verbose         Display verbose output
    -i EXT [EXT ...], --input-extension EXT [EXT ...]
                            The file extensions to look for
    -ext EXT, --extension EXT
                            The output file extension. Default is .html
    -r S, --refresh S     Refresh interval for files. Default is 3 seconds
    --tag TAG             Add self closing tag. eg. --tag macro:endmacro
    --attr-wrapper {",'}  The character that should wrap element attributes.
                            This defaults to ' (an apostrophe).
    --jinja               Makes the necessary changes to be used with Jinja2

Or to simply convert a file and output the result to your console:

hamlpy inputFile.haml

Or you can have it dump to a file:

hamlpy inputFile.haml outputFile.html

Optionally, --attr-wrapper can be specified:

hamlpy inputFile.haml --attr-wrapper='"'

Using the --jinja compatibility option adds macro and call tags, and changes the empty node in the for tag to else.

For HamlPy developers, the -d switch can be used with hamlpy to debug the internal tree structure.

Create message files for translation

There is a very simple solution.

django-admin.py makemessages --settings=<project.settings> -a

Where:

project.settings -- Django configuration file where module "hamlpy" is configured properly.

Reference

Check out the reference.md file for a complete reference and more examples.

Status

HamlPy currently:

has no configuration file. which it should for a few reasons, like turning off what is autoescaped for example
does not support some of the filters yet

Contributing

Very happy to have contributions to this project. Please write tests for any new features and always ensure the current tests pass. You can run the tests from the hamlpy/test folder using nosetests by typing

hamlpy's Issues

hamlpy-watcher compatibility with emacs

While editing emacs for some reason creates broken symlinks like .#base.haml -> [email protected]:1224901752
Hamlpy-watcher do not provide any way to ignore them and fails with traceback when it tries to convert them.

Filter indentation gets screwed up when nested

This:

%head
  :javascript
    $(document).ready(function(){
      $("#form{{form.initial.id}}").submit(form_submit);
      // Javascript comment
    });
  :css
    .someClass {
      width: 100px;
    }
  :cdata
    if (a < b && a < 0)
    {
      return 1;
    }

should compile to this:

<head>
  <script type='text/javascript'>
  // <![CDATA[
    $(document).ready(function(){
      $("#form{{form.initial.id}}").submit(form_submit);
      // Javascript comment
    });
  // ]]>
  </script>
  <style type='text/css'>
  /*<![CDATA[*/
    .someClass {
      width: 100px;
    }
  /*]]>*/
  </style>
  <![CDATA[
    if (a < b && a < 0)
    {
      return 1;
    }
  ]]>
<head>

but instead, it compiles to this:

<head>
<script type='text/javascript'>
// <![CDATA[
    $(document).ready(function(){      $("#form{{form.initial.id}}").submit(form_submit);      // Javascript comment    });
// ]]>
</script>
<style type='text/css'>
/*<![CDATA[*/
    .someClass {      width: 100px;    }
/*]]>*/
</style>
  <![CDATA[
    if (a < b && a < 0)
    {      return 1;    }
  ]]>
</head>

{% elif %} support

Django 1.4 supports, HamlPy should also do.
Now if you print:

if smth
elif smth_else
else
in your haml_template.haml, it will be translated to:
{% if smth %}
{% endif %} # and this is wrong!
{% elif smth_else %}
{% else %}

PyPi lists v0.81.2, but only 0.80.4 is downloaded by setuptools

I don't know if this is PyPI's issue or there was an error while uploading the package, but I can't run buildout with hamlpy version 0.81.2:

Getting distribution for 'hamlpy>=0.81'.
While:
Installing django.
Getting distribution for 'hamlpy>=0.81'.
Error: Couldn't find a distribution for 'hamlpy>=0.81'.

Merge djaml

Would merging djaml make sense? (cc @chartjes)

No HTML DOCTYPE?

I may be blind here but I can't find anywhere in the docs or code about how to specify the HTML doctype. Will this be added soon?

Newlines not working for %img?

Hi,
I noticed that you can separate long dictionary values for a tag like %script. I tried that, and it worked.
But if I try to do this:

%div{'class': 'row'}
    %img{'src': '/static/imgs/ibl_logo.gif', 
        'alt': 'IBL Logo'}
    %br

It does not work and second line, i.e. 'alt' tag prints on a second line. I have tried different ways to see if it could work but I am lost at it and hence decided to file it as a bug. If it is not, my apologies.

Nested if with else does not close parent if

I believe this is a regression from the commit:
"fixing nesting of if and for with else. Addresses https://github.com/jessemiller/HamlPy/issues#issue/5"

HTML-style attributes

It doesn't appear as though hamlpy supports html-style attributes. I'll work on implementing something and submit a pull.

http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html#htmlstyle_attributes_

Inconsistency: custom template tags have to be closed manually

Just a couple of examples.

Works:

#content.partial_update.page.oldSchool
    - block content
        %h1 En el bar has encontrado a tus conocidos juntos. Están alegres y te dicen que van a casarse entre un mes.

But:

- blocktrans with object.duration_as_time as dur
    %span.jtimer.bigger {{ dur }}
    remain
- endblocktrans

I have to close blocktrans manually.

What can be done to make it work automatically?

Is there a way to put variables in an attribute value?

How can I write something that outputs this:

<input type='hidden' name='csrfmiddlewaretoken' value='bb2bc91aba0f29f3aacae0029a822dc9' />

where the value of the value attribute is {{ csrf_token }} in django's templates.

Bug?: translating attributes that are made of objects properties

I encounter a fallowing bug:
parcing the line (taking properties of the variable 'user'):
%i.icon-user{'id': 'UserInfo','data-is-staff': '= user.is_stuff', 'data-id':'= user.pk'}
results in

in order to have it worked propetly i made a workaround:
- with user_is_stuff=user.is_stauff user_pk=user.pk
%i.icon-user{'id': 'UserInfo','data-is-staff': '= user_is_stuff', 'data-id':'= user_pk'}

that results in right output:
{% with user_is_stuff=user.is_stauff user_pk=user.pk %}

{% endwith %}

Logic in attributes dictionary

Sometimes element's attributes can depends on some logic or django variables, for example:

{% for a in b %}
    <a class="link {% if forloop.first %}link-first {% else %}{% if forloop.last %}link-last{% endif %}{% endif %}">this is link</a>
{% endfor %}

I want to do it in haml-way, but this is impossible in the current version of hamlpy

Automatic closing of script tags = not ideal

Right now there's no way to output the ever-so-standard
<script src="my-cool-script.js"></script>

Since you have an explicit way to self-close the tag (/), it would be better to always close the tag in the standard way in the absence of that explicit slash.

document inline variable usage on reference page

https://github.com/jessemiller/HamlPy/blob/master/reference.md should show an example for inline variable usage as otherwise folks would need to literally write

Hello
= user.name
,how are you today?

instead of just Hello #{user.name}, how are you today?

Inline variables were added about two years ago with #17

Haml trans and blocktrans tags are ignored by make_messages utility

I've converted my project to HamlPy and Djaml, and everything works fine except the i18n.

%b
    - trans 'Some message text'

This trans tag is ignored by make_messages command, as well as blocktrans in haml syntax. After running manage.py make_messages I found all the messages from templates commented out as they were not found.

I know I can fall back to usual syntax like

%b {% trans 'Some message text' %}

but it undoes a lot of gains of haml. Is there a way to make the translation parser recognize haml syntax?

disappeared from PyPI

pip install hamlpy

fails with

Could not find any downloads that satisfy the requirement hamlpy

Worked it around by installing directly from github, but would prefer having it installed in a normal way

Error on parsing attribute dict

The wiki example for multiple attributes in a dict doesn't seem to work with the current version of HamlPy:

%div{'id': ('article', '3'), 'class': ('newest', 'urgent')} Content

produces
<div id='article_3' class='('newest', 'urgent')'>Content

commas in tag break

This fails in the new version:

%meta{name:"viewport", content:"width:device-width, initial-scale:1, minimum-scale:1, maximum-scale:1"}

No way to use django variables in the attrubute consitently.

For example, I can't write:

#blah{'class': minor}

Which compiles to:

<div id="blah" class="{{ minor }}"></div>

However I could write:

#blah{'class': '{{ minor }}'}

But this is inconsistent.

hamlpy-watcher.py does not respect directory structure

hamlpy-watcher.py watches all subdirectories in the source directory, but when it compiles the files, it puts them all into the same folder instead of mirroring the directory structure of the source folder.

Whitespace Removal via > and < possible?

Hey there,
first of all: Thank you for your effort in bringing HAML to the Python world. I’m coming from a Ruby background and your implementation makes me feel at home. :)
I’ve a quick question – in the original HAML there is the possibility to control whitespace output.

See the HAML-Documentation about Whitespace

I’m wondering if something similar exists in your implementation … the feature is especially important when it comes to inline-blocks because they are whitespace-aware and I need an output without any whitespace between them.

Any help on the matter would be greatly appreciated. :)

Best regards,
Harry

auto-close ifnotequal and similar

ideally - all standard django tags, i.e. spaceless

Add self-closing support for custom template tags

Example:

- mytag
      Add stuff here

compiles to:

{% mytag %}
      Add stuff here
{% endmytag %}

It'd be nice to support these and just assume/require that we adhere to typical django naming conventions (e.g. the closing tag starts with "end").

Set 'img src' with template variable

would like to set an image's source attribute like this:

%img {'src': '= item.thumbnail'}

but I ended up doing this:

:python
  print "<img src='{{ item.thumbnail }}' />"

I'm not sure if I am doing it wrong or HamPy is doing it wrong. If if turns out this is a bug, I'm happy to step in and fix it, but it could very well be an error on my part.

Version tags would help to install from github repo

As you probably know, pip allows installing from a git repo, see http://www.pip-installer.org/en/latest/requirement-format.html#git
It would be nice if you add tag "v0.2" for the last version.

Thanks

Apostrophes in attributes are escaped (prevents developer from using url tag)

action: "{% url 'django.contrib.auth.views.login' %}"

renders as:

`action='{% url "django.contrib.auth.views.login" %}'``

Which is obviously problematic. Had a poke around the code but I'm not familiar enough with it yet to track down the problem.

Is there a need to escape apostrpohes at all. Given that it's a developers language I don't see any security risk posed by it.

easy_install does not install hamlpy-watcher script

Tabs converted to only 1 space

When parsed tabs are converted to 1 space rather than a full tab in HTML. Maybe there is a setting but have not been able to locate it so answer things question may help others that run into this issue.

Attributes with value "1" are ignored

Attributes that have value 1 are ignored.

Input: %input{value:"1"}
Expected output: <input class='required' value='1' />
Actual output: <input class='required' value />

Test:

    def test_attribute_value_containing_1(self):
        haml = '%input{value:"1"}'
        html = "<input class='required' value='1' />"
        hamlParser = hamlpy.Compiler()
        result = hamlParser.process(haml)
        self.assertEqual(html, result.replace('\n', ''))

I'll take a look at this next week.

id:s instead of classes in example

The following example from reference.md defines "item" and "description" as being class names but in the output they are used as id:s

#collection
    .item
        .description What a cool item!

will compile to:

<div id='collection'>
    <div id='item'>
        <div id='description'>What a cool item!</div>
    </div>
</div>

how to use trans in attributes

I need to inser localized value into input field

%input{'name':'text', 'type':'text', 'value':'localized_value'}

need to be like

%input{'name':'text', 'type':'text', 'value':'
  - trans
    Введите значение'}

How can i do that?

Dashes in attribute name cause error with no quotes

(I'll fix this myself when I get time, just leaving this as a reminder/discussion)

The following code causes a problem

#world{data-page:"hello"}

But not this:

#world{"data-page":"hello"}

Although I don't think HamlPy explicitly supports attributes without quotes, they generally work anyway (and I think it's good to support as it involves less unnecessary typing (equals less errors)). The dash just seems to throw it off

Django variables with plain text are not evaluated

Accordingly to the documentation:

"A Django variable can also be used as content for any HTML element by placing an equals sign as the last character before the space and content"

it works great with tags but how about plain text?

- block heading
    Title=django_variable

result:

<% block heading %>
Title=django_variable
<% endblock %>

fails to write utf-8 characters

HamlPy failed to save file with utf-8 characters.

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

enclose the first argument to url template tag in single quotes

With Django 1.5 we have to enclose the first argument to the url template tag in single quotes thus HamlPy needs to recognize stuff like %a{'href':'{% url 'auth_login' %}'} login without the need to escape the first argument's single quotes with backslashes. Right now one has to use ' as with this example %a{'href':'{% url \'auth_login\' %}'} login in order to get <a href='{% url 'auth_login' %}'>login</a>.

For more info see https://docs.djangoproject.com/en/dev/internals/deprecation/#id2

The url and ssi template tags will be modified so that the first argument to each tag is a template variable, not an implied string. Until then, the new-style behavior is provided in the future template tag library.

Nesting if and for

When you do something like this

    - if var
       - for thing in things
          %div= thing
    - else
       %div no things

The else is always happening for some reason.

css class names containing '-' can only be parsed via dict

I'm trying to work with HamlPy and blueprint-css. For the latter I need css class names like 'span-24'. When I write the following HamlPy markup:
.header.span-24.last
I get:

-24.last

My curent workaround is:
.header.last{'class':'span-24'}
which yields the expected result

The other acceptable solution
%div{'class':('header', 'last', 'span-24')}
doesn't work because of Issue #9

Cannot install with pip

Not sure if this is HamlPy's problem or if it's pip's problem. at any rate, it looks like pip tries to install the Mac OS version, and then fails because it can't find setup.py. I'm running Fedora 15. Here's the relevant error:

inline quoted functions needs to not escape quote

I have a function like this where I need to use inline quoting because it's an attribute:

%meta{"name": "description", "content": "{% block description %}{{ _("Some text to translate") }}{% endblock %}"}

This outputs:

<meta content='{% block description %}{{ _(\'Learning for everyone, by everyone, about almost anything.\') }}{% endblock %}' name='description' />

The _() function is our translation function. It's argument needs to not be quoted! Is it possible to turn this off in some option.

watcher script

First of all: thanks for your work! This is really great!

Do you plan to add a watcher script, such that changed files with the .hamlpy extension get automatically compiled? I was thinking of writing it myself, but I'm not sure if polling would be better than inotify (cross-platform vs. performance). Also, fssm would be an option (http://chriseppstein.github.com/blog/2009/09/07/building-a-jekyll-watcher-with-fssm/), but then again... that's ruby code in a python project...

highlight filter/test broken

Basically nothing about the highlight filter seems to work.

Running hamlpy_test.py you get:

Ran 28 tests in 0.004s
OK

When in fact test_pygments_filter should fail but the test doesn't seem to be run due to indentation problems in hamlpy_test.py, there's mixed tabs and spaces. After fixing that I get:

======================================================================
FAIL: test_pygments_filter (__main__.HamlPyTest)

Looking at PygmentsFilterNode within nodes.py:

from pygments import highlight
from pygments.formatters import HtmlFormatter
from pygments.lexers import guess_lexer, guess_lexer_for_filename


class PygmentsFilterNode(FilterNode):
    def render(self):
        output = self.spaces
        output += highlighter(self.haml, guess_lexer(self.haml), HtmlFormatter())
        return output

guess_lexer_for_filename is an unused import, output+= highlighter should be highlight.

After making these changes it's still broken, I'm currently working on it. Will update later.

support conditional comments

as the 'big' HAML does:

/[if lt IE 9]
    %script{'src': "fix-fckng-ie.com/fixit.js"}

use block name in closing block tag

Rather than ending a block with just {% endblock %}

{% block content %}
...
{% endblock %}

I think it would help readability if it would carry the block name such as

{% block content %}
...
{% endblock content %}

See https://docs.djangoproject.com/en/dev/topics/templates/#template-inheritance for more info.

Outer whitespace doesn't work when there's no parent

I'll revisit this, just leaving it as a reminder while I'm working on #78

This works:

%p
    %li Item one
    %li> Item two
    %li Item three

This doesn't:

    %li Item one
    %li> Item two
    %li Item three

Outer whitespace removal runs when a node tries to render its internal children (this is so we can have access to the rendered siblings to strip the whitespace). In the second example the parent is the RootNode, rather than a HamlNode, so render_internal_nodes is never called.

Javascript

Is there a way to include Javascript on the page? I tried to use the :javascript syntax from Haml, but no luck.

Javascript linebreaks disappear after ( {

I've found a bug that destroys Javascript linebreaks.

Here's the bug in a simple form. The first :javascript becomes broken, the second does not.

:javascript
        (
            {
                a
            }
        );


:javascript

            {
                a
            }
        )

Here's the output:

<script type='text/javascript'>
// <![CDATA[
        (
            {                a            }
        );
// ]]>
</script>
<script type='text/javascript'>
// <![CDATA[
            {
                a
            }
        )
// ]]>
</script>

Here's a template that has the bug too: http://pastebin.com/ZDfjF6ed
