Sublime Text Diagram Plug-in


This is a modified version from jvantuyl‘s work, click here to view details.

This is a plugin that renders diagrams in Sublime Text 2 or 3.

By default, it binds the Alt-D key (preview diagram) and registers a command on the Command Palette. Place your cursor in your diagram or select lines of text and trigger the command. Multiselections are allowed.

To generate diagrams, simplely press Ctrl-B, you will get diagrams in the same directory with source file.

If you wish to override the viewer used, disable start-time sanity checks, or change the default character set for diagram files, search “Diagram Settings” in Command Palette, copy settings from “default settings” to “user settings”, change any one as you wish.


To install from scratch, it’s necessary to have:

To install, click menu Preferences – Browse Packages.., unzip the plugin (or put a checkout of this project for the original version) into the popup directory.


The source is available via git at:

Preview of new syntax & Side by side viewing (multiple column)

This is a preview for activity diagram with “Monokai Extend” color scheme.

Side by side viewing is a more convenience way to edit plantuml diagrams. Each time you view the diagram, the result will refresh in the right one place, no popup window or new view.



If you are using sublime text 3 and keep the default diagram plugin settings, you can ignore this step.

Make sure you are using sublime text 3 and have followed settings:

"viewer" : "Sublime3Viewer", 
"format": "png" // png, svg, eps, latex


press alt D to preview diagram; press alt shift 2 to switch to 2 columns; drag the preview to new column.

Press Ctrl R to list all diagram titles in current file.

Perfectly deal with complex titles. Same process in using title as file name.
