comparison piecrust/generation/blogarchives.py @ 729:e35407c60e00

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
templating: Make blog archives generator expose more templating data. In addition to pagination data, also expose a non-paginating iterator that lists all posts in a source by chronological order.
