Input formats

The format of the files in the content/ directory is determined on the basis if their file extension. The following extensions are recognized by default:

• .md, .mdwn, .mdown, .markdown, .gfm, .mmd: Markdown files. If Pandoc is being used, the input formats .gfm and .mmd will be assumed to be gfm (GitHub-flavored markdown) and markdown_mmd (MultiMarkdown), respectively. Note, however, that currently non-YAML metadata given in MultiMarkdown format is not picked up automatically in .mmd files).

• .htm, .html: HTML. These are typically not standalone HTML documents but will be "wrapped" by the configured layout template. Like other input files, they may have a YAML frontmatter block.

• .tex: LaTeX format. Currently ConTeXt is not supported.

• .org: Org-mode format.

• .rst: ReStructured Text format (RST).

• .textile: Textile markup format.

• .dj: The Djot lightweight markup format.

• .man: Roff man format.

• .rtf: Rich Text Format (RTF).

• .typ: Typst format.

• .jats, .xml: The XML-based JATS (Journal Article Tag Suite) format.

• .docbook: The XML-based DocBook format.

• .tei: The Simple variant of the XML-based TEI (Text Encoding Initiative) format.

• .docx: MS Word DOCX a.k.a. "Office Open XML" format.

• .odt: OpenDocument Text format.

• .epub: The EPUB e-book format.

Pandoc is turned on automatically for all non-markdown, non-HTML formats in the above list. In order to use such content, a sufficiently recent version of Pandoc therefore must be installed.

The list of input formats and how they are handled is configurable through the content_extensions setting in the config file. See Configuration file for details.

Note: The three formats JATS, DocBook and TEI are all XML-based. Files in all three formats would therefore often use the generic .xml extension. However, wmk currently assumes that .xml implies that the JATS format is intended. If you want to force wmk to handle a file with that extension as DocBook or TEI, you would have to add an external YAML metadata file with pandoc_input_format set to the appropriate value.

In-file YAML frontmatter is supported for all of the above except for the three binary formats DOCX, ODT and EPUB. Of course, metadata from an associated external YAML file or inherited metadata applies in all cases. In addition, the "native" metadata seen by Pandoc for most of the formats (more precisely all non-markdown, non-HTML formats other than Textile, which uses YAML frontmatter natively) will be used as a fallback source of in-file metadata, although this is limited to specific standard keys such as title, author and date.

Note that although other input formats are supported, the canonical format is still markdown. Unless there is a special reason to do otherwise it is the most sensible and efficient choice for websites generated using wmk.
