! Future versions of Lektor may change its Markdown parser away from [Mistune](https://github.com/lepture/mistune), and the various markdown related event hooks may be completely removed or work differently if that happens.
|
||
|
|
|
||
|
|
This event is emitted after the markdown has been rendered. This can be used to change the markdown object meta information after the fact.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
[lektor-markdown-header-anchors :ext](https://github.com/lektor/lektor-markdown-header-anchors) uses this to populate a meta var:
|
||
|
|
|
||
|
|
```python
|
||
|
|
def on_markdown_meta_postprocess(self, meta, **extra):
|
||
|
|
prev_level = None
|
||
|
|
toc = []
|
||
|
|
stack = [toc]
|
||
|
|
|
||
|
|
for level, anchor, title in meta['toc']:
|
||
|
|
if prev_level is None:
|
||
|
|
prev_level = level
|
||
|
|
elif prev_level == level - 1:
|
||
|
|
stack.append(stack[-1][-1][2])
|
||
|
|
prev_level = level
|
||
|
|
elif prev_level > level:
|
||
|
|
while prev_level > level:
|
||
|
|
if len(stack) > 1:
|
||
|
|
stack.pop()
|
||
|
|
prev_level -= 1
|
||
|
|
stack[-1].append(TocEntry(anchor, title, []))
|
||
|
|
|
||
|
|
meta['toc'] = toc
|
||
|
|
```
