NppGraphViz

A Notepad++ plugin that sends the current tab's document to a GraphViz preview window.

Installation

1. Install Notepad++

   Notepad++ is a powerful text editor that supports plugins such as NppGraphViz. Go to the Notepad++ homepage at https://notepad-plus-plus.org. Download and install the latest version.

2. Install Graphviz

   Graphviz is a collection of progams that make diagrams from a simple text language. Go to Graphviz's homepage at www.graphviz.org. Download and install the latest version.

3. Install NppGraphViz

   If you installed 64-bit Notepad++, then download the 64-bit NppGraphViz.dll

   If you installed 32-bit Notepad++, then download the 32-bit NppGraphViz.dll

   Make a "NppGraphViz" folder in Notepad++'s plugins directory, and move the NppGraphViz.dll into it. On a typical install, the full path would be "C:\Program Files\Notepad++\plugins\NppGraphViz\NppGraphViz.dll" or "C:\Program Files (x86)\Notepad++\plugins\NppGraphViz\NppGraphViz.dll"

4. Start Notepad++

   Start Notepad++. Click "Plugins" from the file menu, you should see "Graphviz" if the plugin successfully installed.

Features

• Hit the F9 key to preview or refresh your current tab's document with a selected GraphViz program (e.g. dot.exe).
• Save the image with any of GraphViz's supported file types.
• Zooming and dragging. The mouse wheel adjusts the zoom. Holding down the left or right mouse button allows dragging the preview image. The middle mouse button resets the preview.

{
    Stop->Collaborate
    Collaborate->Listen
