Thinking about how to implement this in ikiwiki, perhaps a conditional
pagespec would be best (which could be tidied up into a template)
- [[!if test="current_date_before(<TMPL_VAR date>)"
+ \[[!if test="current_date_before(<TMPL_VAR date>)"
then="""[[!tag draft]]"""
else="""[[!meta date="<TMPL_VAR date>"]]"""
]]
…pre-supposing a scheme whereby tagging 'draft' hides the page from an
aggregation somewhere. With a template, this could collapse to
- [[!template id=publishafter date="Thu Aug 30 14:13:06 BST 2012"]]
+ \[[!template id=publishafter date="Thu Aug 30 14:13:06 BST 2012"]]
This would require implementing the `current_date_before` pagespec.
publish date has occurred. That could perhaps be implemented via a small plugin
which defined a pagespec which ensured the page was 'dirty':
- [[!if test="current_date_before(<TMPL_VAR date>)"
+ \[[!meta date="<TMPL_VAR date>"]]
+ \[[!if test="!current_date_before(<TMPL_VAR date>)"
then="""[[!tag draft]][[!dirty]]"""
- else="""[[!meta date="<TMPL_VAR date>"]]"""
]]
The following is an attempt at the dirty part:
If anyone has any clues as to why this doesn't work
