This is my version of a simple OpenSCAD editor.

I run Linux and all of the current editors are for Windows or OSX. I decided to use node-webkit and CodeMirror Editor to make an all systems compatible editor.

Goto my Github page for the latest downloads and updates: https://github.com/iceblu3710/OpenSCAD_Editor

Features:

• Available on Linux, Mac OSX and Windows
• Autoformatting, Block Comment/Uncomment
• Code folding
• Syntax highlighting (In progress)
• Find & Replace (In progress, needs UI)
• Autocomplete (Implementation only)

Instructions:

• Download one of the node-webkit prebuilt binaries (v0.4.0 — Jan 18, 2013)
• Open/Install OpenSCAD and in the menu select View -> Hide Editor and Design -> Automatic Reload and Compile
• Unzip the node-webkit binary and cut/copy the nw.exe and nw.pak files into the OpenSCAD editor folder
• Run nw.exe and open a .scad file in both the editor AND in OpenSCAD itself
• Whenever you make changes in the editor press F5 or Ctrl-S and OpenSCAD will render the changes
