clickmd 1.0.2

Markdown rendering for CLI applications with syntax highlighting

clickmd

Markdown rendering for CLI applications with syntax highlighting.

clickmd provides beautiful terminal output with:

• 🎨 Syntax highlighting for code blocks (Python, TypeScript, JSON, YAML, Bash, etc.)
• 📝 Markdown rendering with headers, bold, links, and more
• 🔧 Zero dependencies for core functionality
• 🖱️ Optional Click integration for CLI decorators

Installation

# Core package (no dependencies)
pip install clickmd

# With Click support
pip install clickmd[click]

Quick Start

Basic Usage (No Dependencies)

from clickmd import md, echo

# Render markdown with syntax highlighting
md("""
# Hello World

This is **bold** and this is a [link](https://example.com).

```python
def greet(name: str) -> str:
    return f"Hello, {name}!"

""")

Smart echo - auto-detects markdown

echo("## Status Update") echo("Regular text without markdown")

### With Click Integration

```python
import clickmd as click

@click.group()
def cli():
    """My awesome CLI tool"""
    pass

@cli.command()
@click.option("--name", "-n", default="World")
def hello(name: str):
    """Say hello"""
    click.md(f"""
## 👋 Hello, {name}!

Welcome to **clickmd** - making CLIs beautiful.
    """)

if __name__ == "__main__":
    cli()

Markdown Elements

### Heading 3

**Bold text** and regular text.

[Links](https://example.com) are supported.

```python
# Code blocks with syntax highlighting
print("Hello, World!")

• List items
• Are rendered
• Correctly """)

### MarkdownRenderer Class

For more control, use the `MarkdownRenderer` class directly:

```python
from clickmd import MarkdownRenderer
import sys

renderer = MarkdownRenderer(use_colors=True, stream=sys.stdout)
renderer.heading(1, "My Title")
renderer.codeblock("python", 'print("Hello!")')

md("""
```log
