When editing Markdown, reStructuredText or dot graph files, I'd like to see an instant preview of the file in a second pane.

Is there a text editor for linux that is able to execute an external command whenever the text is changed, and displays the results of that command in a second pane?


There is https://github.com/sverweij/atom-graphviz-preview-plus which adds a live-preview pane to the Atom editor, for dot graph files.

  • There is also an extension for Visual Studio Code, which is more snappy and just faster than Atom (subjectively) both on Linux and Windows where I use it.
