Litemark is a lightweight Markdown dialect originally created to be the markup language for the Codegame Platform project. When you run litemark from the command line interface without any arguments, the Litemark Viewer opens and displays the rendered demo.

Litemark demo rendered in the Litemark Viewer

litemark-demo.md (plain text)

The name Litemark refers to both the markup language and the distribution package.

The distribution package comes with an API, a command line interface, and a graphical viewer.

It is easy to break an arbitrary plain text into a flat list of tokens:

import litemark


plain_text = """Hello *World* ! Visit the [repository](https://github.com/pyrustic/litemark) !"""

for token in litemark.scan(plain_text):
    # a token instance is a named tuple with 2 fields: name and data 
    print(token)

The output:

Token(name='STRING', data='Hello ')
Token(name='BOLD', data='World')
Token(name='STRING', data=' ! Visit the ')
Token(name='LINK', data=('repository', 'https://github.com/pyrustic/litemark', ''))
Token(name='STRING', data=' !')

The formal names of the tokens are defined in litemark.Element:

class Element:
    CODEBLOCK = "CODEBLOCK"
    HEADING = "HEADING"
    BOLD = "BOLD"
    ITALIC = "ITALIC"
    WARNING = "WARNING"
    OVERSTRIKE = "OVERSTRIKE"
    IMAGE = "IMAGE"
    INLINK = "INLINK"
    LINK = "LINK"
    STRING = "STRING"

The token's data field represents a string for all elements except the following:

• Element.CODEBLOCK: 2-tuple (str-title, str-content)
• Element.HEADING: 2-tuple (int-level, str-content)
• Element.IMAGE: 3-tuple (str-inline, str-path, str-alt)
• Element.INLINK: 3-tuple (str-inline, str-path, str-alt)
• Element.LINK: 3-tuple (str-inline, str-URL, str-alt)

To open litemark-demo.md in the graphical Viewer:

$ litemark

To open a specific litemark file in the graphical Viewer:

$ cd /path/to/root
$ litemark my-file.md

Note:

Litemark is created for use in a desktop application. Thus, the Litemark Scanner assumes that the images referenced in a litemark document are relative to the root directory. The root directory is simply the current working directory. For this reason, you must first do a cd (change directory) to the root before rendering a document.

It is easy to embed a Litemark Viewer in your Python desktop app:

import litemark
import tkinter as tk

root_directory = "/home/alex/demo"
litemark_filename = "/home/alex/demo/document.md"

# your GUI
gui = tk.Tk()
gui.geometry("500x500+0+0")

# let's embed a Litemark Viewer in this GUI

# -- text widget
text_widget = tk.Text(gui)
text_widget.pack(expand=1, fill=tk.BOTH)

# -- the viewer instance
viewer = litemark.Viewer(widget=text_widget, root=root_directory)
viewer.open(litemark_filename)
viewer.readonly = True

# done !
gui.mainloop()

This is a work in progress. A reference documentation will be released soon.
