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.

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>

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.

Hello,

In some case the Element node have no attribute element (in comments it seems), so the function crash when trying to call self.element in : hamlpy/nodes.py", line 282, in _post_render

To reproduce :

Write this in a file : test.haml

-# My comment
    #my_div
        my text

then execute hamlpy test.haml

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 %}

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").

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.

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.

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.

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.

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:

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

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

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>

as the 'big' HAML does:

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

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

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

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.

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"
f0ab3a6

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?

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_

HamlPy failed to save file with utf-8 characters.

Traceback (most recent call last):
  File "/usr/local/bin/hamlpy", line 9, in <module>

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

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?

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

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.

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.

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:

While:

Basically nothing about the highlight filter seems to work.

Running hamlpy_test.py you get:

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:

======================================================================

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.

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.

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 %>

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

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.

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.

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.

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?

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

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 %}

Would merging djaml make sense? (cc @chartjes)

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?

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.

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:

$ pip install hamlpy

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.

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...

running the command:

(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

This fails in the new version:
