Cocoduino is an IDE for the Arduino platform written in native Cocoa. It's designed to be simple and easy to use and is a replacement for the official Arduino IDE.

Cocoduino plays perfectly well together with the official Arduino IDE without any compatibility problems.

You can download the latest version of the application here.

Make sure you have the official Arduino IDE installed, because Cocoduino relies on tools that are shipped with it.

• Mac OS X 10.7 Lion (64 Bit)

Cocoduino offers nearly the same features as the official Arduino IDE:

• Sketchbook
• Serial Monitor
• Integrated Examples
• Multiple Files or Tabs
• Build and Upload to your Arduino

Additionally, it supports Mac OS X features like:

• Autosave
• Versions
• Fullscreen

Last but not least, there is also:

• Syntax Coloring
• Basic Code Completion

1. Build Process

   As there is no official CLI interface for the Arduino build process, there is no guarantee that Cocoduino can compile all sketches that work with the official Arduino IDE.
   There might be problems with more complex sketches.

2. File Architecture

   The official Arduino IDE uses plain text files for sketches with a path extension of .ino. Those sketches need to be located inside a directory with the same name as the main sketch file's name.
   When using NSDocument, you'd actually want to use a binary data file which is far more powerful, because you can store additional metadata within the file. Or store multiple files in a single one, etc.
   In order to preserve full compatibility to the official Arduino IDE, Cocoduino uses some hacks in order to support the same file architecture as the official Arduino IDE. There are some disadvantages when doing this: Autosave doesn't work without additional work and Versions is buggy. All in all, I think this was the right decision.

3. Upload using Programmers

   While Cocoduino supports nearly all Arduino boards theoretically, the use of programmers is neither tested nor "officially supported".

• Clean up the syntax coloring library
• More advanced code completion (Cocoduino is ignoring the keywords.txt files!)

1. Will you add…?

   Only if I think it'd improve the application. You are free to fork the project, though. (That's why it's open source.)

2. My sketch won't compile

   If you have problems with one particular sketch, please post to the issues.

3. Application crashes

   To err is human. Please post the crash log to the issues.

Cocoduino uses (modified) versions of the following third party libraries:

• Sparkle
• SCEvents
• AMSerialPort
• MASPreferences
• PSMTabBarControl
• Fragaria

The tool used for the actual build process is (modified and with additional preprocessing):

• Ino
