typermd 0.1.4

Markdown rendering for Typer CLI applications — drop-in replacement with syntax highlighting

typermd

Markdown rendering for Typer CLI applications with syntax highlighting.

typermd is a drop-in replacement for Typer that adds beautiful markdown rendering to your CLI output — with zero code changes beyond the import.

Like clickmd is for Click, typermd is for Typer.

Installation

pip install typermd

Quick Start — Zero Code Changes

Just change your import:

# Before
import typer

# After — that's it!
import typermd as typer

Everything works exactly as before, but now typer.echo() auto-detects markdown and renders it with colors, and you get a new typer.md() function for explicit markdown output.

Minimal Example

import typermd as typer

app = typer.Typer()

@app.command()
def hello(name: str = typer.Option("World", "--name", "-n")):
    typer.md(f"""
## 👋 Hello, {name}!

Welcome to **typermd** — making Typer CLIs beautiful.

```python
import typermd as typer
typer.md("# It's that easy!")

""")

if name == "main": app()

## Features

### Drop-in Typer Replacement

All Typer API is re-exported: `Typer`, `Option`, `Argument`, `Context`, `run`, `echo`, `style`, `colors`, `confirm`, `prompt`, `progressbar`, `launch`, `edit`, and more.

### Auto-detecting `echo()`

```python
# Plain text — works normally
typer.echo("Regular output, no formatting applied")

# Markdown detected — auto-rendered with colors
typer.echo("## Status: **running**")

# Force plain output
typer.echo("## Not rendered", auto_markdown=False)

Explicit Markdown with md()

typer.md("""
# Deploy Report

| Service | Status |
|---------|--------|
| API     | ✅ OK  |
| DB      | ✅ OK  |

```bash
kubectl get pods -n production

""")

### Syntax Highlighting

Supported languages:

| Language | Aliases | Highlights |
|----------|---------|-----------|
| Python | `python`, `py` | Keywords, strings, comments, decorators |
| JavaScript | `javascript`, `js` | Keywords, strings, template literals |
| TypeScript | `typescript`, `ts` | Same as JavaScript |
| Bash | `bash`, `sh`, `shell`, `zsh` | Commands, comments, variables |
| JSON | `json` | Keys, strings, numbers, booleans |
| YAML | `yaml`, `yml` | Keys, values, comments |
| TOML | `toml` | Sections, keys, strings |
| SQL | `sql` | Keywords, strings |
| Rust | `rust`, `rs` | Keywords, types, attributes |
| Go | `go` | Keywords, strings |
| Dockerfile | `dockerfile` | Instructions |
| Log | `log` | Errors (red), warnings (yellow), success (green) |

### Tables

```python
from typermd import table

table(
    headers=["Name", "Version", "Status"],
    rows=[
        ["typermd", "0.1.0", "✅ OK"],
        ["typer", "0.9.0", "✅ OK"],
    ],
)

Panels

from typermd import panel

panel("Deployment complete!", title="Success")

Structured Logger

from typermd.logger import get_logger

log = get_logger("deploy")
log.info("Starting deployment...")
log.step(1, 3, "Building artifacts")
log.step(2, 3, "Running tests")
log.step(3, 3, "Deploying")
log.success("Deployed to production!")
log.warning("Cache may need warming")
log.error("Rollback required")
log.action("Next", "Monitor dashboard")

Themes

from typermd.themes import set_theme, list_themes

list_themes()         # ['default', 'monokai', 'solarized', 'nord']
set_theme("monokai")  # Switch theme

Or via environment variable:

export TYPERMD_THEME=monokai
