GitHub Action Inputs

Input Path

with:
  input_path: value

(Required) (Path) or (File) The location of the folder containing your .md or .markdown files, or a path to a single .md or .markdown file that you would like to convert.

*Note, previous versions of this action accepted the input_dir input. This is still accepted as input for backwards compatibility, but passing a directory as input_path now carries out the same functionality.

Images Directory

with:
  images_dir: value

(Path) The location of the folder containing your images, this should be the route of all images. So of you had images located at images/about/file.png and images/something-else/file.png you would pass the value images.

Output Directory

with:
  output_dir: value

(Path) The location of the folder you want to place the built files.

Image Import Prefix

with:
  image_import: value

(String) The path you use to import your images that can be replaced with the server URL. For example if you had <img src="./images/something-else/file."> you would pass ./images as this is replaced by https://localhost:3000 during the build process.

Build HTML

with:
  build_html: value

(Boolean) Whether to also create a .html file.

Build PDF

with:
  build_pdf: value

(Boolean) Whether to also create a .pdf file (defaults to true. After all, this is the intended behaviour).

CSS Theme

with:
  theme: value

(File) The location of the CSS file you want to use as the theme.

with:
  extend_default_theme: value

(Boolean) Whether to extend your custom CSS file with the default theme

Highlight CSS Theme

with:
  highlight_theme: value

(File) The location of the CSS file you want to use as the code snipped highlight theme.

with:
  template: value

(File) The location of the HTML/Mustache file you want to use as the HTML template.

with:
  table_of_contents: value

(Boolean) Whether a table of contents should be generated

Input Types

A few pieces to describe what input each value expects.

Path

A path will most likely be from your repository's route, it should not be prefixed or suffixed with a /. The path should look like so docs/topic/featureDocs or writing/category.

String

A string could be anything, and using YAML (or YML) does not need to be encased in quotes.

Boolean

This should be either true or false.

File

This should be the direct path to a file, it should not be prefixed with a /. An example: styles/markdown-theme.css.
