How to develop the Arduino IDE both online and offline!

Hi, I would like to know how to develop Arduino IDE both online and offline, hopefully with tutorials, thanks a lot!

Did you check the forum stickies?
Or just jump right in the with your first forum post with gay abandon?

It's not at all clear to me what you are asking. Please provide a detailed description of what you mean by "develop Arduino IDE". Are you saying you want to do development work on the Arduino IDE's source code, or only that you want to use the Arduino IDE for writing and uploading sketches for your Arduino board?

From past posts, this might be a troll.

I would like to know how to develop the Arduino IDEs from scratch. The IDE itself.

The Arduino IDE's source code is here:

build instructions here:

for anything else, consult one of the many Java tutorials or references available online. If you get stuck with something specific to the Arduino IDE, you can ask for help here.

Since you say "IDEs", I suppose you mean Arduino Web Editor and Arduino Pro IDE as well? Neither of these are completely open source at this time, but there are components you can work on:

Have fun!
