smartdoc-cli 0.1.3

SmartDoc: A tool to generate API documentation for FastAPI, Flask, and Django projects.

SmartDoc CLI

SmartDoc CLI is a command-line tool that automatically generates Markdown, HTML, and PDF API documentation for web frameworks like FastAPI, Flask, and Django.

---

Installation

pip install smartdoc-cli

(For testing with Test PyPI)

pip install --index-url https://test.pypi.org/simple/ smartdoc

---

Usage

Run this command inside your project directory.

Example command:

smartdoc generate \
  --app your_app.main \
  --framework fastapi \
  --output api_docs.md \
  --html \
  --pdf

For FastAPI:

smartdoc generate --app your_project.main --framework fastapi --output docs.md --html --pdf

For Flask:

smartdoc generate --app your_project.main --framework flask --output docs.md --html --pdf

For Django:

smartdoc generate --app your_project.main --framework django --django-settings your_project.settings --output docs.md --html --pdf

---

Troubleshooting SmartDoc

If running smartdoc generate causes import/module errors, follow these steps:

Common Error:

ModuleNotFoundError: No module named 'apps'

Fix:

# For Windows PowerShell
$env:PYTHONPATH="project"
smartdoc generate --app main --framework fastapi --output api_docs.md --html --pdf

Replace main with the filename (without .py) that runs your FastAPI app.

Checkpoint	Description
PYTHONPATH set?	Point to folder where apps/, main.py, etc. exist
Module correct?	Use --app main not full path like project.main
Inside virtualenv?	Make sure .venv is activated
Imports relative?	Use from apps..., not project.apps...

Tip

If you want to avoid setting PYTHONPATH every time, create a PowerShell script run_smartdoc.ps1:

$env:PYTHONPATH="project"
smartdoc generate --app main --framework fastapi --output api_docs.md --html --pdf

---

smartdoc.json – Custom Configuration File

Place this in your root directory (same level as .venv, your_projects, etc.):

For FastApi

{
  "app": "main",
  "framework": "fastapi",
  "output": "api_docs.md",
  "html": true,
  "pdf": true,
  "pythonpath": "project_folder"
}

For Django

{
  "app": "project_name.urls",
  "framework": "django",
  "output": "api_docs.md",
  "html": true,
  "pdf": true,
  "pythonpath": "project_name",
  "django-settings": "project_name.settings"
}

For Flask

{
  "app": "app",  // path to your Flask app file (e.g. app.py without .py)
  "framework": "flask",
  "output": "api_docs.md",
  "html": true,
  "pdf": true,
  "pythonpath": "."
}

1. Then use a custom script to run it:

Here’s a reusable Python script (run_smartdoc.py) to load from this config:

run_smartdoc.py

import os
import subprocess
import json

with open("smartdoc.json") as f:
    config = json.load(f)

os.environ["PYTHONPATH"] = config["pythonpath"]

cmd = [
    "smartdoc",
    "generate",
    "--app", config["app"],
    "--framework", config["framework"],
    "--output", config["output"]
]

if config.get("html"):
    cmd.append("--html")
if config.get("pdf"):
    cmd.append("--pdf")

subprocess.run(cmd)

Run it with: python run_smartdoc.py

Note: Additional step for Django and Flask:

1. Django

In Python Script you need to set the DJANGO_SETTINGS_MODULE environment variable.

Update run_smartdoc.py like this:

os.environ["DJANGO_SETTINGS_MODULE"] = config.get("django-settings", "")

2. Flask

In flask you only have to give the path of .py file which contains `Flask(__name__)` in the place of app.

---

2. Makefile (For Mac/Linux or Git Bash)

If you're on Linux/macOS or using Git Bash on Windows, you can use a Makefile.

Makefile

PYTHONPATH=your-path

generate-docs:
	PYTHONPATH=$(PYTHONPATH) smartdoc generate \
		--app main \
		--framework fastapi \
		--output api_docs.md \
		--html \
		--pdf

Run it with: make generate-docs

NOTE: Make the necessary changes for Django and Flask

CLI Options

Option	Description
