Just thought I'd add a note to bump this suggestion. I agree, should be a good additional feature. Gitlab has it integrated as well and I must say it works effectivly. I am also interrested in using such integration to document specifications stored in a GitHub Repository and potentially publish it to a github.

I would also like to see this added. While github developers track this feature implementation ticket internally, can somebody from dev team please share progress and ETA? I would love to see this as well. We currently store separate.

This works, but having them rendered directly by GitHub would be great.

How to edit Markdown + UML in Visual Studio Code

The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I want to publish some programming documentation I have in a public available repository. This documentation has formatted text, some UML diagrams, and a lot of code examples. I think that GitHub or GitLab are good places to publish this.

To publish the UML diagrams, I would like to have some easy way to keep them updated into the repository and visible as images in the wiki. I don't want to keep the diagrams in my computer or on the cloudedit them, generate an image, and then publish it every time. Is there a way to put the diagrams in the repository in PlantUML syntax would be ideallink them in the markdown text, and make the images auto-update every time the diagram is updated?

This way is significantly different and simpler than the answer below; it uses the PlantUML proxy service :. This method suffers from not being able to specify the SVG format it defaults to PNGand it is perhaps not possible to work-around the caching bug mentioned in the comments. After trying the other answerI discovered the service to be slow and seemingly not up to the latest version of PlantUML. I've found a different way that's not quite as straightforward, but it works via PlantUML.

As such, it should work anywhere you can hotlink to an image. It exploits the!

PlantUML Basics 👨‍🎨

The markdown file links to a PlantUML source that includes the diagram's source. This method allows modifying the source in GitHub, and any images in the GitHub markdown files will automatically update.

But it requires a tricky step to create the URL to the indirection. This URL won't change. Just put a valid puml file in the repository and include a link to this site in the documentation. Unfortunately, it doesn't seem to work with GitLab.

Mermaid is supported out of the box. The other answers discuss GitHub, but it is worth noting that GitLab has native integration for this, if you are deploying in-house. For some reason, they have never activated the feature on their public offering. There are tickets open to activate the feature. If you are working of an in-house hosted solution, there are instructions available in the administration documentation. Learn more.

To use the plugin with Python-Markdown you have these choices:. For example, for Python 2. A good choice may be the user-site path, for example bash syntax :. For example:. But before to use it, you need to configure which PlantUML binary to use: a local binary, or a remote server. The plugin expects a program plantuml in the classpath. If not installed by your package manager, you can create a shell script and place it somewhere in the classpath.

This would avoid modifications of the plantuml script.

For example, with a diagram like:. On Windows can be used the following plantuml. From version 2. This speedups a lot the diagrams rendering but needs to send the diagram source to a server. You can download the war and deploy in a servlet container, or you can run it as a docker container. This command uses a custom version of the plantuml command which will download the expected version of PlantUML for tests execution without clobbering the system.

Message 6 of Do you hate drawing diagrams for technical documentation? Seems like no sooner you finish a draft, new refinements come along, forcing you to change not only the text but the picture as well. If you're using a traditional drawing tool, that can be tedious. UML is the acronym for Universal Modeling Language, an effort to standardize an iconography for software design that first appeared 25 years ago. Though perhaps it has not lived up to the larger ambitions of its designersit still offers a consistent way to visualize various facets of software design.

Drawing UML diagrams is tedious, but what if you could instead describe a UML diagram textually, in a way that you could include it directly in a Markdown-based document, see both diagrams and formatted text in a preview as your are editing it, and in addition can export the Markdown as HTML or PDF?

Your text and diagrams are seamlessly integrated in one file. That's where PlantUML comes in Visual Studio Code a. VS Code has become a popular editor for various computer languages, including Markdown. That extension is called plantumland you can install it either by searching for it in the extensions panel click on the extension icon :.

An example:. What's more, the diagram in the Preview pane is kept in sync with the UML as described the Markdown document. No need to refresh the Preview pane.

That's great, but what if you want to export a diagram from within the Markdown? For that you'll need a little help from your friends In order to export individual diagrams, I need to install GraphVizwhich is "open source graph visualization software".

It works in conjunction with the plantuml extension installed earlier. Unlike plantuml, it is not a VS Code extension, but an executable. You also have the option to export all diagrams within a Markdown document command palette option "PlantUML: Export Current File Diagrams"which will create separate image files for each diagram.

For instance, my Markdown doc is named basic. This adds a second preview pane in addition to VS Code's native Preview pane. For some reason, two versions show up in my Extension pane when I searched for it; I chose the latest:.

All you need to do is provide some front matter in your markdown that directs Puppeteer how to layout the PDF:. It takes a few seconds, but the PDF will eventually be generated and your default browser will open not necessarily Chrome with the PDF document displayed. You don't have to be a UML expert to convey ideas through diagrams, but you will find your diagrams easier to modify through text than though a drawing tool.

On top of that, the ability to embed diagrams in your Markdown documentation and export it in different formats is a big plus. If you read this far, tweet to the author to show them you care.

I can include as many plantuml segments as I want in my Markdown, and the diagrams can be of any type supported by PlantUML. No worries! I have workarounds, as will be shown. For some reason, two versions show up in my Extension pane when I searched for it; I chose the latest: Now you will see two preview controls above your Markdown document: That first icon activates the new Markdown Preview Enhanced pane With the pane open, you can now right click on it and export to various formats, such as HTML or PDF.I have been wanting to write this post for months.

You can see it being used in my plantbuddy and techradar projects on GitHub. Using it in different places and for various purposes I came across a bunch of issues that I want to share in this post. There are different diagram types available being described with custom syntax but following a common scheme. This post will not go into the details of each of those diagram types because the PlantUML website does a pretty good job at describing sequencecomponentactivity and the other diagram types.

A very important aspect for developing software and writing documentation is to keep it in sync. One part is to update documentation if the code itself is updated. Another important part is versioning - usually software is versioned using git or similar systems. By putting the documentation into the same repository as the code you make sure to always look at the correct state of documentation for a respective point in time.

For that reason I love putting all my documentation either within the sourcecode as comments or as Markdown files next to the sourcecode. One thing I was always lacking with this approach is visualizing things. One other benefit PlantUML has over the mentioned tools is that by defining your diagrams in plain text you make them diff-able in pull requests. Reviewers can always see what changes have been made and easily compare changes to the diagram with changes made inside the code. The basic syntax of PlantUML is very concise and builds a good foundation for the different diagram types.

It is also well very smart in the way that it allows diagrams to be written with different flavors e. Same goes for macros and definitions that allow you to compose larger diagrams or a common library for your team. Instead the diagram is inferred by a deterministic algorithm in the rendering process.

This is beneficial when specifying the diagram because you only focus on the content - comparable to writing a LaTeX document. For sequence and activity diagrams the automatic layouting works great even for very large diagrams. After you built a few diagrams and notice how easy it is to just move lines of code up and down and have changes in the code immediately reflect in your documentation you will love the automatic layouting.
