Is it possible to make an extension that draw lines on the background? You can decorate a lot of thing but I can't find a way to draw colored lines.
I would like to see the flow of my data (inspired by visual programming).
Something like that (but the like drawn under the text) :
Keep in mind vscode is an add-on to Electron, which is a webbrowser in a desktop raiment. So what you see are webpages and hence everything what's possible on a webpage (with a node.js basement) is also possible in vscode - at least in theory. I say "in theory" because after all vscode is a text editor and limits interaction in a way that supports this goal. So, what you can is either some drawing/graphics or add extensions that work in normal editor pages. You certainly don't want to write your own text editor interface within vscode.

For a half year now, I carry an innovative idea for a modern way of code editing. I just realized what Visual Studio Code extensions are already capable of and made me wonder.
The idea is that a real time code render mode for code editors where code is visualized like rendered documentation (for example Doxygen). Non-commented lines of code are displayed like collapsable codeblocks and documentation comments are displayed as the surrounding markdown/HTML/LaTeX document.
This rendered view still can be edited and navigated in same way as the classic text view so that new graphical elements appear after typing them as text into a comment. Therefore, rich interactive documentation reading (like hiding/showing parts, jumping across locations with hyperlinks) and code editing would be combined into one activity without time needed for switching between both or mapping Documentation with actual code locations. Different from the original literate programming idea, the file's physical content is unchanged and doesn't complicate the process or source code reading.
It's conceptually how Moodle text editors work (HTML code view and render view) or like using a graphical word processor to visualize source code instead of a single monospace text. Of course, the cursor would move along lines in their visually presented order and not in their file's actual order.
Do you know, if such a real time render mode is possible in VSCode?
Did someone had such an idea and made an extension?
btw:
This "render mode" idea is actually quite generic and could be used as general customizable GUI technology that would allow GUI elements to be navigated, edited via an underlying text representation.
I am trying to determine if its possible to provide a "richer" experience when using TreeViews in a VS Code extension. The default explorer view has the ability to do things provide custom text coloring for items (such as red when a file has an error or yellow if its been changed). However, the only highlight I can seem to find in TreeItems is only able to highlight text in an item without control over color but only select when the highlight starts/stops.
I would really like to take advantage of the same tree experience provided by the VS Codes extensions view but it does not seem to be restricted by the same API as other extensions (makes sense).
Any recommendations? I am considering just doing a webview that holds my own "TreeView" but wanted to see if there are other options before going down that rabbit hole.
I am writing a small tools for VS Code and the tool will need to draw arrows between symbols in the code.
Something along these lines.
Please forgive my skills with Paint.
What it is the best way to achieve this effect in VS Code?
What you want is not possible. The editor output in vscode is a list of DOM nodes (divs for the lines, spans for the syntactic elements). You cannot draw lines between DOM nodes.
If you had full control over the editor you could add an overlay over the entire text to draw the lines, but then you have to take care not to disturb the normal behavior of the editor and, after all, you don't have that kind of control.
A webview is not a good approach, as it would not only require to duplicate the work the normal editor does, it's also isolated and has no direct access to the main application, which means actions, language server support etc. don't work
yes sure use this Rainbow Brackets
its draw an arrow between the start and the end .

I was looking for a better code editor for my projects and wanted to give VSCode a try. But I couldn't find where to customize the syntax highlighting settings. What I actually need is to change the background color of embedded languages within a file so that I can identify different parts of the code a lot easier.
I have this PHP file which contains, HTML, CSS and JavaScript and I'd like to set different background colors for all 4 languages within this single file. Is this possible with VSCode? or does anyone know a code editor that supports this? UltraEdit supports this but it has so many other shortcomings.

e.g. I write a markdown document and include a line like [myimage](/mypath.jpg) to see the image in a big size above or below this line.
When I'm writing markdown I regularly have to look at an embedded file. At the moment I have to use a split layout and switch my attention between the text buffer and the preview. That's slowing me down and distracting.
What I mean is a full size preview that can fill the whole width of the buffer and is permanently shown. This is offered by the emacs markdown-mode (see this image with a command named "markdown-toggle-inline-images".). This is also available in sublime text e.g. via an add-on named sublime_zk. This is possible in atom with add-ons like preview-inline or inline markdown images.
This would allow to use VSCode like a WYSIWYG md-editor like typora but with all the benefits of using your daily edtior. This should also be interesting for programmers - at least on hackernews typora is regularly praised as the best markdown editor (see e.g. here)
I didn't see an addon for this. Something related was discussed about two years ago in issue 7689 - but this only concerns a mini preview in the gutter or if you move the mouse over a link. For this there is already the add-on Image preview.
This is not possible as of VS Code 1.29. The VS Code api does not provide a way to insert custom elements like images into the editor.
The two closest existing APIs:
The code lens api: CodeLensProvider. These allow you to insert additional clickable commands into an editor (such as displaying a reference count above a function) but these can only be text buttons
The hover api: HoverProvider. Hovers can contain images since they display markdown content. However they are only displayed when the user hovers over them
