Deprecation warning: Call to deprecated function (or staticmethod) meta

[franktisellano]

Getting the following warning:

lektor_markdown_header_anchors.py:22: DeprecationWarning: Call to deprecated function (or staticmethod) meta. (Use ImprovedRenderer.lektor.meta instead.)
  renderer.meta['toc'].append((level, anchor, Markup(text)))

Mostly posting this as an FYI. I'm planning on submitting a PR with a fix soon.

FWIW, I think (due to a bug in Lektor? — I don't understand why, at this point [eta: I've figured it out; see next comment]) the warning is being attributed to the wrong line. I think the warning should reference line 61, where the ImprovedRenderer.meta property is accessed:

lektor-markdown-header-anchors/lektor_markdown_header_anchors.py

Lines 59 to 61 in 38b4f6d

	class RendererMixin_mistune0(object):
	def header(self, text, level, raw):
	return render_header(text, level, self.meta)

---

Changing RendererMixin_mistune0 so that it accesses meta the same way as RendererMixin_mistune2 should (untested) eliminate the warning.

lektor-markdown-header-anchors/lektor_markdown_header_anchors.py

Lines 63 to 66 in 38b4f6d

	class RendererMixin_mistune2(object):
	def heading(self, text, level):
	meta = self.lektor.meta # Lektor >= 3.4
	return render_header(text, level, meta)

It turns out that the reported line number issue is due to differences between the master branch and the latest release
(0.3.1...master) of lektor_markdown_header_anchors.

If possible, try running the version from git master and see if you still get the deprecation warning.

(I don't have the permissions necessary to be able to publish a new release to PyPI. I'm not completely sure who does. Maybe @nixjdm?)
