tal:repeat always inserts a new line inbetween repeating elements. Whitespace is sometimes important in HTML and unnecessary whitespace can cause styling problems in some older browsers.

It would be great if Chameleon could support repeating elements, or text, all on the same line.

The equivalent bug in zope.tal project is https://bugs.launchpad.net/zope3/+bug/229931

It seems tricky to do this in a backwards compatible way. A rule that would make sense to me would be that if the repeating element is the first non white space element on its line then add a new line otherwise don't.

e.g.

    <ul><li tal:repeat="item items" tal:content="item"></li></ul>

would result in

    <ul><li>item 1</li><li>item 2</li><li>item 3</li></ul>

but

    <ul>
        <li tal:repeat="item items" tal:content="item"></li>
    </ul>

would result in

    <ul>
        <li>item 1</li>
        <li>item 2</li>
        <li>item 3</li>
    </ul>

Hi

I made some changes to Chameleon to get it working correctly on Windows. The problems are related to the way Windows handles temporary files. It should fix Launchpad Bug #731803.

I also changed the unit tests because they suffer from the same problem. However I'm not sure if everything gets clean up and I think there will be some temp files that are not deleted after the test is run.

Steps to reproduce

• Start with a Plone 4.1 instance using Chameleon
• Create new site
• Add a News Item to the News folder, including an image
• View the News Item
• Click on the image in the news item view, which takes you to the image_view_fullscreen view. This gives the error above.

Notes

I verified this only happens with Chameleon enabled, and not with the default Plone 4.1

And, 22% increase in pages/second when tested with ab. Awesome!

Fixes #327

@d-maurer This is a draft as food for discussion on a fix for #327. The code change will flag up any unclosed tag - but is that really desirable? As the failing test shows it will also flag up simple tags that few people close, like <br>. But it feels a fix shouldn't introduce code to introspect the unclosed tag to see if it's OK to ignore it.

We discovered a changement in rendering of boolean attributes in the option tag since release 3.8.0 (using python 3.8). Example: <select> <option value="" tal:attributes="selected True">Selected</option> <option value="a" tal:attributes="selected False">Not selected</option> <option value="ok" tal:attributes="selected None">OK</option> </select> will render to: <select> <option value="" selected="True">Selected</option> <option value="a" selected="False">Not selected</option> <option value="ok">OK</option> </select> Can somebody confirm this? The workaround for now would be to pin down the version to 3.7.4.

Use the default_marker integration parameter rather than a locally defined marker("default") as representation of the TALES default object.

This fix would resolve "https://github.com/zopefoundation/Zope/pull/853".

chameleon.template.BaseTemplate.digest() prepends the pathname (minus extension) to the digest under this condition:

        if self.filename is not BaseTemplate.filename:
            digest = os.path.splitext(self.filename)[0] + '-' + digest

However, when self is <PageTempate None> this throws the following error:

*** AttributeError: 'NoneType' object has no attribute 'rfind'

This happens in the following scenario:

1. Install a clean Plone 4.3.15 buildout
2. Add Products.PloneFormGen 1.7.23 to the buildout
3. Add five.pt to the buildout
4. Create a new Plone site, activate PloneFormGen
5. Create a FormFolder
6. Go to the mailer Mail Adapter which is added by default to a new Form Folder
7. Edit the mailer
8. Save it without making any changes

Result: You will not be able to save. The following validation error for the textarea containing the default mail template is displayed:

Compilation Failed

exceptions.AttributeError: 'NoneType' object has no attribute 'rfind'

I'm not sure if there is something that PloneFormGen needs to do differently, but I do know that changing the condition to this fixed the problem:

        if self.filename and self.filename is not BaseTemplate.filename:

Is self = <PageTemplate None> because we are being called from __init__()? Either way, this is a TTW template, so it should not have a filename.

This is the tail of the stack where the error happens:

How can I translate tag value in chameleon template?

Something like this

<meta name="keywords" content="need to be translated"/>

or this

<input type="submit" value="need to be translated"/>

I use meta as slot

<meta metal:fill-slot="description" name="description" content="need to be translated"/>

Thanks!

This following snipped of generated Chameleon code is taken from the Zope tests which fail on Python 3.9 because of generated invalid syntax:

            # <Substitution "y/z | python:'||'[:0]" (15:27)> -> __attr_name
            __token = 486
            try:
                __attr_name = _static_4444020112(getitem('y'), econtext, True, ('z', ))
            except (AttributeError, LookupError, NameError, TypeError, ValueError, _NotFound, _Unauthorized, _LocationError, ):
                __token = 492
                __attr_name = _guarded_getitem('||', :0)

The error is in the last line in :0.

In Python 3.8 the generated code is valid and looks like the following:

            # <Substitution "y/z | python:'||'[:0]" (15:27)> -> __attr_name
            __token = 486
            try:
                __attr_name = _static_4561636800(getitem('y'), econtext, True, ('z', ))
            except (AttributeError, LookupError, NameError, TypeError, ValueError, _NotFound, _Unauthorized, _LocationError, ):
                __token = 492
                __attr_name = _guarded_getitem('||', get('slice', slice)(None, 0, None))

I was using 3.9.0b3 on MacOS but the error is also on TravisCI, see https://travis-ci.org/github/zopefoundation/Zope/jobs/703426836

I have a situation where I need to force translation to a specific language in a template. Would it be possible to support that with a i18n:language attribute? Usage would look like this:

<button i18n:translate="" lang="en" i18n:target="en">Continue</button>
<button i18n:translate="" lang="nl" i18n:target="nl">Continue</button>
<button i18n:translate="" lang="de" i18n:target="de">Continue</button>

Which would result in:

<button lang="en">Continue</button>
<button lang="nl">Verder</button>
<button lang="de">Weiter</button>

I am not sure this is an issue -- I'm just trying to understand the code. Here goes:

The load expression uses __loader, which is initialized as _loader in the init of PageTemplateFile. This is always created as an instance of the loader_class.

The loader in chameleon.loader keeps a cache of templates in self.registry through a decorator.

If I create a page template loader and load a page template file, and then load it again, it'll come from the cache. But that page template file creates its own loader again, so that when the load expression fires it will set it up in a new cache. This means that if page template a loads up m, and page template b then loads up m again, b won't benefit from the cache of a -- it'll load m again.

I run into all this because I'm trying to create a custom loader, which I'd like to propagate into the templates it loads, so that any load expression in that template also uses that loader. But custom loaders don't propagate to load expressions, do they? Instead I have to initialize it with its own class as a keyword argument, I think.

Again, I may get this all wrong -- I'm trying to read the code and I may be misunderstanding something. But I thought it was worth reporting.

Hi there,

Is there anyway that we can have any VS code extension for Chameleon as the templating language? I see that a similar feature exists in PyCharm professional.

Thanks, Sam

Just importing pkg_resources becomes slower and slower the more packages are installed. Even on fast machines with SSDs this can add a second or more to the startup time.

In Zope PageTemplates there is a handy method called "find_bad_templates", which does the obvious: traverse through all PageTemplates in a Folder and listing those, where the "_cook" method fails.

However, we encountered a PageTemplate where the traversing stops with a "UnicodeDecodeError". The reason is that described method catches the Chameleon Exceptions and saves them as a string. Schematically:

def _cook(self):
    ...
    try:
        ..._cook()
    except:
        etype, e = sys.exc_info()[:2]
        self._v_errors = [
            "Compilation failed",
            "%s.%s: %s" % (etype.__module__, etype.__name__, e)
    #               ^^                                       ^
            ]

If an exception occurs, it is converted to a string. And that can fail, if the token contains a non-ascii char. We can reproduce it with Python2 like this:

from chameleon import exc, tokenize
body = u'<p>ein text mit uumlaut\xfc</p>'
string = body[3:-4]
token = tokenize.Token(string, 3, body)
e = exc.LanguageError('Invalid define syntax', token)
str(e)

The last line throws an exception:

Traceback (most recent call last):
  File ...
    str(e)
  File ".../chameleon/src/chameleon/exc.py", line 192, in __str__
    text += "\n" + line
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 47:
  ordinal not in range(128)

I will make a pull request to fix this...

To iterate over a list, you can access the repeat variable by referencing the iteration item variable name:

<div tal:repeat="item range(10)">
  <p tal:condition="repeat.item.even">Even</p>
  <p tal:condition="repeat.item.odd">Odd</p>
</div>

However it doesn't seem possible to access the repeat variable when iterating over dict items:

<div tal:repeat="(key, value) my_dict.items()">
  <p tal:condition="repeat.key.even">Even</p>
  <p tal:condition="repeat.key.odd">Odd</p>
</div>

Essence of the traceback:

...
KeyError: 'end'

During handling of the above exception, another exception occurred:

...
AttributeError: end

During handling of the above exception, another exception occurred:

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:
