**[Install](#installation)** &middot; **[History]** &middot; **[Roadmap]** &middot;
**[Contribute][contributing]** &middot; **[Open Source](#open-source)**

> > This is BETA software. Native drawio files created with these tools _should_ work

## Installation

```bash
mamba install -c conda-forge ipydrawio  # recommended, or...
conda install -c conda-forge ipydrawio  # or...
pip install ipydrawio[all]
```

## Features

- `ipydrawio`
  - full support for JupyterLab
  - best-effort support for JupyterLiteⓁ and RetroLabⓡ
  - Edit multi-page [documents][]
    - with nearly the same UI and features as [diagrams.net][drawio]
    - in many file formats
      - Drawio/mxgraph XML, SVG, PNG
      - or Jupyter Notebooksⓡ
    - with all the Drawio templatesⓡ
      - plus some Jupyter ones
  - Jupyter [rich display][] output
  - Jupyter [Widgets][]
  - Basic collaborative editing
    - requires the `--collaborative` flag, added in JupyterLab 3.1+
    - token sharing, _a la_ [jupyterlab-link-share], or a custom connector (no known
      yet)
    - no presence indicators for other editors
- `ipydrawio-export`
  - Export print-quality PDF from diagramsⓁⓡ
    - optionally include editable Drawio XML as a PDF attachment
    - > _BEWARE: some **heavy**, maybe fragile dependencies, `mamba` recommended_
      ```bash
      mamba install -c conda-forge ipydrawio-export  # recommended, or...
      conda install -c conda-forge ipydrawio-export  # or...
      pip install ipydrawio ipydrawio-export
      ```
- `ipydrawio-mathjax`
  - include rich LaTeX and AsciiMath typesetting in diagrams

> ⓡ: unavailable in RetroLab Ⓛ: unavailable in JupyterLite

## Examples

## Usage

> Please see the [docs] for full information

- Try on [![binder-badge][]][binder]
  - or follow the [Installation instructions](#installation) and **Start JupyterLab**
- Open a diagram, by doing one of:
  - Creating a
    <img src="https://raw.githubusercontent.com/deathbeds/ipydrawio/main/packages/ipydrawio/style/img/drawio.svg" width="24"/>
    Diagram\_ from the [Launcher][]
  - Uploading a diagram created on [diagrams.net](https://diagrams.net) with the _[File
    Manager][]_ and double clicking it
  - Building diagrams by interactively computing in `IPython` with `ipydrawio.Diagram`
  - Use the `application/x-drawio` MIME renderer
- Use the _[Command Palette][]_ to _Export Diagram_ to various formats
  - > **NOTE**: some of the built-in UI features of drawio don't work properly inside an
    > IFrame in JupyterLab, and are difficult to robustly disable: please see _Diagram_
    > options available in the _Command Palette_ and various _Main Menu_ menus.

## Configuring

### UI Themes

Your default theme can be changed in the JupyterLab Main Menu:

- open _Settings_
- open _Diagram Theme_
- select your theme
- all open documents will change to this theme (prompting if not saved)
- all future documents will use this theme

The different themes have some advantages and disadvantages:

| theme     | default | full menu | layers | pages | light | dark | rough |
| --------- | :-----: | :-------: | :----: | :---: | :---: | :--: | :---: |
| `atlas`   |         |    ✔️     |   ✔️   |  ✔️   |  ✔️   |      |       |
| `dark`    |         |    ✔️     |   ✔️   |  ✔️   |       |  ✔️  |       |
| `kennedy` |         |    ✔️     |   ✔️   |  ✔️   |  ✔️   |      |       |
| `min`     |   ✔️    |           |   ✔️   |  ✔️   |  ✔️   |  ⚙️  |       |
| `sketch`  |         |           |   ✔️   |       |  ✔️   |  ⚙️  |  ✔️   |

> Note that `rough` will change how many shapes look

### Drawio Configuration and URL parameters

Use _Advanced Settings_ to modify drawio embedding parameters

> See the [schema] for full details of the (known) supported options as well as the
> [upstream docs] for all parameters, though IPyDrawio might not support them... yet.

### PDF: Lab and Server extensions

`ipydrawio-export` can generate print-quality PDF. This approach relies on a headless
browser, powered by [@jgraph/draw-image-export2], `puppeteer`, and `nodejs`.

- **native dependencies** as required to appease `puppeteer`
  - if running in `docker`, this can be a bit trial-and-error
  - for more, see the [binder][apt-txt] and CI.
- `nodejs>=18,<19` from `conda` or your system package manager
  - **NOTE**: this relies on being able to install `puppeteer` (and other **arbitrary
    dependencies** with `jlpm` for now **when first used**
- `pip install ipydrawio-export` or `conda install -c conda-forge ipydrawio-export`

> For example to install all the dependencies:
>
> ```bash
> conda install -yc conda-forge ipydrawio-export ipydrawio-mathjax
> ```

Optionally, pre-install the dependencies:

```bash
jupyter ipydrawio-export provision
```

> By default this will install to `{JUPYTER_DATA_DIR}/ipydrawio_export`, but can be
> tuned with:
>
> - the `$IPYDRAWIO_DATA_DIR` environment variable
> - `IPyDrawioExportManager.drawio_export_workdir` in `jupyter_config.json`
>
> Additionally, the (large) chromium browser download can be tuned with the
> `$IPYDRAWIO_PUPPETEER_CACHE_DIR` or `$PUPPETEER_CACHE_DIR` environment variables.

Once installed, you can use the in-browser tools _Export Diagram as PDF_ as well as the
command line:

```bash
jupyter ipydrawio-export <name of document>
```
