🏎 Quickstart

This tool exports an Azure DevOps wiki as PDF. Therefore, you need to git clone the target wiki to a computer. You can get the clone link of the wiki in the top right of the wiki homepage:

To clone this wiki, use the following command: git clone https://dev.azure.com/mmelcher/AzureDevOps.WikiPDFExport/_git/AzureDevOps.WikiPDFExport.wiki

The result should look like this:

Once you have cloned the wiki, you must download the Azure DevOps WikiPDFExport tool. azuredevops-export-wiki.exe (~30MB)

You can drop it right into the cloned folder and execute it there. Launched without parameters, the tool will detect all wiki files next to it and convert it to a PDF called export.pdf right next to it. Similar to this pdf.

If you need more control over the output, please see the Configuration Options below or by launching the tool with --help parameter.

💪 Features

The tool currently supports the following:

• Export all wiki pages (and sub pages) in the correct order including styles and formatting.
• Includes pictures (remote and relative urls)
• Table of Contents
• If you link to other wiki pages, the link in the PDF will work, too.
• Everything self-contained. Download the .exe file, run it, done.
• It is fast. A PDF with 160 pages is created in less than a second.
• Tool can be used as part of a build, see BuildTask
• Supports emoticons :) ⚠ ℹ
• Mermaid supported
• Workitems can be referenced and will be included in the pdf as link with the current status, e.g. #7.
• Math/Latex formulas are rendered

🛰 Requirements

The tool is developed as .NET 6 application, therefore you need to have the runtime installed. Download is available here. It requires a x64 windows or linux runtime.

⚙ Configuration Options

--attachments-path

Path to the .attachments folder. If not provided, the .attachments is assumed to be located under the folder of the wiki (-p/--path).

-b / --breakPage

For every wiki page a new page in the PDF will be created

--chrome-path

Path of the chrome or chromium executable. It'll be used if mermaid diagrams support is turned on (-m/--mermaid). If not specified, a headless version will be downloaded.

--css

Path to the stylesheet to overwrite the look of certain components in the PDF. See styles.css for examples. To get the html file, use the --debug flag to inspect and style it.

-c / --highlight-code

Highlight code blocks using highligh.js

-d / --debug

Debug mode. Logs tons of stuff and even exports the intermediate html file

--disableTelemetry

Disables the telemetry tracking, see Telemetry

--exclude-paths

Skip pages whose path matches the regular expression patterns.
To exclude any files in the folders "Scrum" and "Release" but not the file "Released-Version.md", use --exclude-paths /Scrum/ /Release/ (paths are internally normalized to forward slashes and the passed values will be surrounded by .* automatically to enable partial matches)

--filter

Filters the pages depending on the page yaml tags.

--footer-template, --header-template,

Headers and footers can be added to the document by the --header-* and --footer* template arguments respectfully. In header and footer string supplied the following variables will be substituted. See PDF options from puppeteer.

• [pageNumber] Replaced by the number of the pages currently being printed
• [topage] Replaced by the number of the last page to be printed
• [totalPages] Replaced by the current date in system local format

--footer-template-path, --header-template-path

Provide a path to html files that will be added as header and footer. See example-footer.html, example-header.html.

--globaltoc

Title for a global table of content for all markdown files. When not specified each markdown creates its own toc if defined

--globaltocposition

Order of TOC within all files (starting from 0). When not specified TOC will be printed on the first page

--include-unlisted-pages

By default only pages listed in .order files are considered. Setting this option any Markdown file (.md) found will be included as-well.

--no-frontmatter

If you want to remove the frontmatter / YAML tags from the PDF.

--chrome-timeout

Timeout for Chrome operations in seconds (default 30 seconds).

--open

Opens the PDF file after conversion. Great for development, not great in a build task.

-o / --output

The path to the export file including the filename, e.g. c:\export.pdf

--organization

Azure Devops organization URL used to convert work item references to work item links. Ex: https://dev.azure.com/MyOrganizationName/

-p / --path

Path to the wiki folder. If not provided, the current folder of the executable is used.
If you only want to convert a subfolder and have images, then you must provide the path to the attachments folder with --attachments-path.

--pat

Personal access token used to access your Azure Devops Organization. If no token is provided and organization and project parameters are provided, it will start a prompt asking you to login.

--pathToHeading

Add path of the file to the header

--printbackground

Enable print background when using no header/footer template.

-s / --single

Path to a single markdown file to convert to PDF. If you want to write your changelog in the wiki, this is your parameter to only convert a single page.

-v / --verbose

Verbose mode. Logging will added to the console window

Running in Docker

To build the Docker Image run the following commands (replace <VERSION>):

dotnet publish -r linux-x64 -c Release -p:Version=<VERSION> --no-self-contained  -o output/linux-x64
docker build --pull --rm -f "Dockerfile" -t azdowiki-pdf-export:latest "."

Launch a container:

docker run -it -v ${pwd}:/usr/root/wiki -w /usr/root/wiki azdowiki-pdf-export:latest bash

Change the volume mapping (-v ${pwd}) to the location of your wiki and then run azuredevops-export-wiki -p . to generate your PDF.

😲 Limitations

So far the following limitations are known:

• If headers are not formatted properly (#Header instead of # Header), they are rendered incorrectly. I might fix that in the future.
• The tool lacks proper testing because I only have two realistic wikis available. Want to contribute one?
• Currently, no pdf bookmarks are created (see chromium issue).
• Tags in Azure DevOps must be closed properly - if you leave a strikethrough (~~) open, then all the following content will be striked through.

⚖ License

See license

🎯 Telemetry

The tool uses Application Insights for basic telemetry:

• The duration of the export and the count of wiki pages is tracked and submitted to Azure.
• In the case of an error, the exception is submitted.
• No wiki data/content is submitted.

❓ FAQ

Some pages are missing?

Please check the .order files in your wiki if the pages are listed in there.

The emoticons are missing in the PDF?

Please check if you have page file that are encoded (e.g. Test%20dFiles.md)

There is an error 'Qt: Could not initialize OLE (error 80010106)'.

Yes, please ignore for now.

Does it also work for Github?

Yes, but there the .order files are missing to determine the sort order of pages. You would need to create them by yourself, but it is possible.

Does it run on Linux?

I only tested Ubuntu 18.04 - but there it works. I installed the following packages:

apt-get install -y gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget libgbm-dev ttf-ancient-fonts

♥ Thanks

In this tool uses open source libraries that do the actual work - I just combined them to get the export as PDF:

1. CommandLineParser to parse the command line
2. MarkDig to parse markdown files to HTML.
3. dotnet-warp to release a self-contained exe file
4. puppeteer-sharp to convert mermaid markdown to SVG
