Currently in DocPad, metadata frontmatter is formatted using YAML by default, and if you want to use CSON instead, you have to write
--- cson at the beginning for each file.
I suppose this is useful as a way of reminding the developer which format the document’s metadata uses. But I also think it would be nice, for those who always prefer CSON over YAML, if we could instead set the default frontmatter format in the
docpad.coffee configuration file.
