Command-Line GUI

On Linux, Mac (but also on Windows) a full fledged editor GUI appears with

% msc-gen --gui

It has a built-in editor with color-syntax highlighting, syntax hints, smart indent, automatic compilation and more. On Windows it cannot edit charts embedded as an OLE object, but it can embed the chart text in a PNG file (on all platforms).

Maggot (deprecated)

A simplistic Linux GTK GUI editor is available at the same repository with

% sudo apt install maggot
% maggot

All it has now is a very simple text editor pane with color syntax highlighting, a preview of the resulting chart, and exporting function to PNG files with the MSC source code embedded.
