markdown-os 0.9.15

Developer-focused markdown editor served from a local CLI.

Markdown-OS

Developer-focused markdown editor that runs as a local web server. Edit in the browser with live preview, Mermaid diagrams, syntax highlighting, and auto-save.

Desktop installers for macOS and Windows are published from GitHub Releases. The desktop app bundles the local server and opens with a picker-first workflow, so users do not need Python or a terminal after installation.

Install

pip install markdown-os

Or with uv:

uv tool install markdown-os

To upgrade after installing with uv: uv tool upgrade markdown-os

Desktop app

Download the latest desktop installers from GitHub Releases:

• macOS: .dmg
• Windows: .exe

The desktop app keeps the same editor UI, but launches in a native desktop shell with recent files/folders and native open dialogs.

Usage

Single file:

markdown-os open ./notes.md

Directory (markdown workspace):

markdown-os open ./my-notes

The app opens in your browser. If port 8000 is in use, the next port is tried. Options: --host, --port.

Example file

Generate a showcase markdown file:

markdown-os example                    # creates example.md in current directory
markdown-os example ./docs/showcase.md # custom path
markdown-os example --open             # generate and open in the editor

Use --force / -f to overwrite an existing file without prompting.

Publishing (maintainers)

Use the release helper from a clean working tree on the branch you want to publish (usually master):

uv run python scripts/release.py

It reads [project].version from pyproject.toml, asks whether to bump major, minor, or patch, updates the file, then runs git add / git commit (only pyproject.toml) / git push -u origin <current-branch> / annotated git tag / git push origin <tag>.

Useful options:

• --dry-run — print the planned version and git steps without changing files or running git.
• -y / --yes — skip the final confirmation prompt.
• --version X.Y.Z — set an exact version string and skip the bump menu.
• --branch master — push a specific branch (defaults to your current branch).
• --repo /path/to/checkout — run against another clone.
• --allow-dirty — proceed when other files are modified (still only commits pyproject.toml).

Manual sequence (equivalent when you are on master):

1. Bump version in pyproject.toml.
2. Commit and push: git add pyproject.toml && git commit -m "chore: release X.Y.Z" && git push origin master
3. Tag and push: git tag -a vX.Y.Z -m "Release X.Y.Z" && git push origin vX.Y.Z

The GitHub workflow runs on tag push and publishes to PyPI only when the tag matches the package version.
