# CM MkDocs Plugins - MkDocs Page to PDF

An MkDocs plugin to generate a PDF file for each MkDocs page using `pyppeteer` (chrome headless) and add a download button.

This was forked from the great work done by <https://github.com/brospars/mkdocs-page-pdf> and changed to allow individual PDF export instead of excluding paths from export, due to the need to speed up the PDF generation process for a vast number of files and an issue with the glob pattern used for the exclude parameter, since the plugin implementation of PurePath.match doesn't match recursively so we have to specify all possible paths to exclude, significantly slowing down the process. Parsing the FrontMatter YAML to search for a specific key:value speeds the process immensely.

## How to use

Install the package with pip:

```shell
pip install mkdocs-cm-page-to-pdf
```

Enable the plugin in your mkdocs.yml:

```yaml
plugins:
  # - ...
    - mkdocs-cm-page-to-pdf # should be last
```

### Options

To set different options use the following syntax.

```yaml
plugins:
  # - ...
    - mkdocs-cm-page-to-pdf:
        # Options here
```

* ``disable`` (bool): Disable pdf rendering useful to quickly disable it without removing the plugin config. Defaults to ``False``.
* ``disableOnServe`` (bool): Disable pdf rendering when using `mkdocs serve`. Defaults to ``False``.

The following options are directly induced from [pyppeteer options](https://pyppeteer.github.io/pyppeteer/reference.html?highlight=pdf#pyppeteer.page.Page.pdf) :

* ``scale`` (float): Scale of the webpage rendering, defaults to ``1.0``.
* ``displayHeaderFooter`` (bool): Display header and footer.
  Defaults to ``False``.
* ``headerTemplate`` (str): HTML template for the print header. Should
  be valid HTML markup with following classes.
  * ``date``: formatted print date
  * ``title``: document title
  * ``url``: document location
  * ``pageNumber``: current page number
  * ``totalPages``: total pages in the document
* ``footerTemplate`` (str): HTML template for the print footer. Should be valid HTML markup with the same classes as ``headerTemplate``.
* ``printBackground`` (bool): Print background graphics. Defaults to``False``.
* ``landscape`` (bool): Paper orientation. Defaults to ``False``.
* ``pageRanges`` (string): Paper ranges to print, e.g., '1-5,8,11-13'. Defaults to empty string, which means all pages.
* ``format`` (str): Paper format. Defaults to ``A4``.
* ``margin`` (dict): Paper margins.
  * ``top`` (str): Top margin, accepts values labeled with units, defaults to ``20px``.
  * ``right`` (str): Right margin, accepts values labeled with units, defaults to ``20px``.
  * ``bottom`` (str): Bottom margin, accepts values labeled with units, defaults to ``20px``.
  * ``left`` (str): Left margin, accepts values labeled with units, defaults to ``20px``.
* ``pageLoadOptions`` (dict): Page load options (see [this](https://pyppeteer.github.io/pyppeteer/reference.html?highlight=goto#pyppeteer.page.Page.goto)).
  * ``timeout`` (int): Maximum time in milliseconds, defaults to ``30000``.
  * ``waitUntil`` (str): When to consider navigation succeeded, defaults to ``load``.
* ``exclude`` (list) : List of glob pattern to exclude. Disregarded when ``include`` is set to ``True``.
* ``include`` (bool) : Manually define files to export. Defaults to ``False``.

If using the `include` option, insert a `pdfexport: true` key in the FrontMatter YAML of any Markdown file you wish to export to PDF. Example:

```yaml
---
pdfexport: true
---
```

### Troubleshooting

#### Running in a docker container (ci/cd)

Depending on what image you are using you may encounter some issue running `pyppeteer` : `Browser closed unexpectedly`.

This is due to some missing shared libraries used by Chrome Headless.

Related issue: <https://github.com/pyppeteer/pyppeteer/issues/194>

See this [article](https://www.cloudsavvyit.com/13461/how-to-run-puppeteer-and-headless-chrome-in-a-docker-container/)
and this [guide](https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md#running-puppeteer-in-docker)  

#### Slow build on serve

You can use `disable` or `disableOnServe` options to disable the pdf rendering (entirely or on serve) but you can also use the `mkdocs serve --dirtyreload` flag to only rebuild modified files on the fly.

#### Blank page at the end

Due to a [chrome bug](https://github.com/brospars/mkdocs-page-pdf/issues/9) a blank page can appear at the end of the PDF you can remove it by adding the following to you extra.css :

```css
body {
    contain: strict;
}
```

## Special thanks

The original version of this plugin (here: <https://github.com/brospars/mkdocs-page-pdf>) was inspired by [mkdocs-with-pdf](https://github.com/orzih/mkdocs-with-pdf) and [mkdocs-pdf-export-plugin](https://github.com/zhaoterryy/mkdocs-pdf-export-plugin) but without using `weasyprint` and instead `pyppeteer` (chrome headless) to have a render closer to what you have in your chrome browser.
