pttk frontmatter
pttk frontmatter OPTIONS [INPUT_FILENAME] [OUTPUT_FILENAME]
The frontmatter action allows you to extract metadata from a text document that uses the Markdown style frontmatter. By default it will return the documents frontmatter as a JSON structure. If you include a root level attribute name then you can extract the value as a unquoted string. By default frontmatter can read from standard input but if you provide a filename it’ll ready from the file instead. Likewise it writes to standard out but if an output filename is provided it write to that file instead.
Here is an example of extracting a frontmatter from “mypost.md” markdown file.
pttk frontmatter mypost.mdHere is an example of extracting a “title” from the frontmatter when combined with Stephen Dolan’s jq.
