ImportError: cannot import name ‘HTMLParseError’

[kseistrup]

Acrylamid yields an exception when installed on Python 3.5:

$ acrylamid
'acrylamid.tasks.imprt' ImportError: cannot import name 'HTMLParseError'
Traceback (most recent call last):
  File "/tmp/acrylamid-test/lib/python3.5/site-packages/acrylamid/helpers.py", line 422, in discover
    mod = sys.modules[modname]
KeyError: 'acrylamid.tasks.imprt'

During handling of the above exception, another exception occurred:

ImportError: cannot import name 'HTMLParseError'

There is no such error as HTMLParseError in Python 3.5, so perhaps something like this could be an interim solution:

try:
    from html.parser import HTMLParseError
except ImportError as e:
    # HTMLParseError is removed in Python 3.5. Since it can never be
    # thrown in 3.5, we can just define our own class as a placeholder.
    class HTMLParseError(Exception):
        pass

[kseistrup]

Please.

[posativ]

Sorry, the project is unmaintained. Just apply your patch.

[kseistrup]

Fair enough.

Perhaps it would be prudent to state on the project here and on acrylamid's homepage that the project is unmaintained so that people can look for other static site generators.

[posativ]

You're right. I'll update the project's description. You can use a different Python version, though.

[kseistrup]

You can use a different Python version, though.

I can, but I prefer using the default python interpreter of “my” Linux distro, currently v3.5.2. I'd better look around for another blogging engine…

[posativ]

Literally every linux distribution™ ships a package with Python 2 because of dependencies. You can even use virtualenv (also available in many distributions). The blog engine depends on your use case. There is no real allrounder.

[kseistrup]

I know that ArchLinux also ships Python 2.7, but I prefer to not use it when there are alternatives. I'm also aware of virtualenv, but it would still require me to install Python 3.4 to be able to run acrylamid on Python 3, and that “solution” is suboptimal.

I favoured acrylamid partly because it's written in Python, which allows me to contribute with bug reports and pull requests, but I reckon I might have to broaden my horizon a bit.

[posativ]

I'm not currently using my engine and I do not use Python that often anymore. I just expected that Python 3 will no longer introduce breaking changes. Silly me.

[kseistrup]

I agree, they shouldn't have introduced that change in Python 3.5. But they did. Bummer.

[posativ]

I generally would not recommend a project that is that inactive. The project supports many different python libraries, that all changed somewhat and are no longer compatible with Acrylamid. The ecosystem is evolving very fast. I would recommend Pelican, at least it has a huge community.

[posativ]

I've updated the project status. If you find a similar, active project, let me know.
