Documentation¶
The documentation page lists out all of the relevant classes and functions for generating markdown documents in Python.
snakemd¶
The snakemd module contains all of the functionality for generating markdown files with Python. To get started, check out Usage for information. Otherwise, see the rest of this document for details on all the functionality provided in snakemd.
- snakemd.new_doc(name: str) Document ¶
Creates a new SnakeMD document. This is a convenience function that allows you to create a new markdown document without having to import the Document class. This is useful for anyone who wants to take advantage of the procedural interface of SnakeMD. For those looking for a bit more control, each element class will need to be imported as needed.
doc = snakemd.new_doc("README")
New in version 0.9.0.
- Parameters:
name – the file name of the document without the extension
- Returns:
a new Document object
- class snakemd.generator.CheckBox(text: str, url: Optional[str] = None, bold: bool = False, italics: bool = False, code: bool = False, image: bool = False, checked: bool = False)¶

- Parameters:
text (str) – the inline text to render
url (str) – the link associated with the inline text
bold (bool) – the bold state of the inline text; set to True to render bold inline text (i.e., True -> bold)
italics (bool) – the italics state of the inline text; set to True to render inline text in italics (i.e., True -> italics)
code (bool) – the italics state of the inline text; set to True to render inline text as code (i.e., True -> code)

a verification object from the violator
- class snakemd.generator.Verification¶
Bases:
object
Verification is a helper object for storing errors generated when creating a markdown document. This object is largely used internally to verify the contents of a document, but can be accessed through the various verify() methods throughout the library by the user.
