mddoco 0.1.0

Markdown to HTML/PDF document converter

mddoco

A CLI tool that converts markdown files to a single HTML (or future PDF) document.

Installation

pip install mddoco
playwright install chromium

Or for development:

pip install -e .
playwright install chromium

Playwright (Chromium) is required for PDF output only. HTML output works without it.

Usage

mddoco [OPTIONS] INPUT_PATH

INPUT_PATH can be a directory (all *.md files are found recursively and sorted) or a single .md file.

Options

Option	Short	Default	Description
--output PATH	-o	.	Directory to write the output file
--format [html|pdf]	-f	html	Output format
--title TEXT	-t	(none)	Document title shown at the top of the page
--theme NAME		default	Theme to use for rendering
--toc / --no-toc		off	Generate a table of contents
--toc-depth N		3	Maximum heading depth included in the TOC (1–6)

Examples

Convert all markdown files in a directory:

mddoco ./docs

Convert a single file:

mddoco README.md

With a title, TOC, and custom output directory:

mddoco ./docs --title "My Project" --toc --output ./out

Output

All matched markdown files are combined into a single HTML document in the output directory. The filename is derived from the input folder or file name.

Themes

Themes are self-contained Jinja2 HTML files with embedded CSS. The default theme includes:

• Clean typographic layout
• Syntax-highlighted code blocks
• Styled tables and blockquotes
• Optional document title
• Optional table of contents
• Mermaid.js diagram support (loaded only when diagrams are present)

Graph diagrams

Use ```graph fenced blocks with a JSON payload. The only required field is data.

Minimal example — all defaults applied:

```graph
{
  "data": {
    "x": ["Jan", "Feb", "Mar"],
    "Sales": [100, 150, 120]
  }
}
```

Series are inferred from the data keys (everything except x). Each series defaults to a line chart in blue.

Full schema:

Field	Required	Default	Description
data.x	yes	—	Category labels
data.<name>	yes	—	Values for each series (one key per series)
title	no	(none)	Chart title
orientation	no	vertical	vertical or horizontal
show_legend	no	true	Show the legend
width_px	no	640	Width in pixels
height_px	no	480	Height in pixels
min / max	no	—	Axis bounds
series	no	(auto)	Override series definitions (see below)

Series fields (all optional when auto-generated):

Field	Default	Description
label	(data key)	Must match a key in data
type	line	bar, line (solid), or line2 (dotted)
colour	(palette)	Colour string, or list of colours per bar
marker	false	Show point markers (line types only)

Full example:

```graph
{
  "title": "Sales vs Target",
  "orientation": "vertical",
  "show_legend": true,
  "data": {
    "x": ["Jan", "Feb", "Mar", "Apr", "May"],
    "Sales":  [85, 92, 78, 96, 110],
    "Target": [90, 90, 90, 90, 90]
  },
  "series": [
    { "label": "Sales",  "type": "bar",  "colour": "#3498db" },
    { "label": "Target", "type": "line", "colour": "#e74c3c", "marker": false }
  ]
}
```

Mermaid diagrams

Use standard fenced code blocks in your markdown:

```mermaid
graph TD
    A[Start] --> B[End]
```

mddoco detects mermaid blocks automatically and loads the Mermaid.js CDN only when needed.
