Created for the classroom. Designed for learning.
Simple tools to help you get started.
WHY TURTLEEDIT
Small features that make learning easier.
Spend less time learning the tools.
Spend more time learning to
code.
Make small mistakes visible.
Line numbers are always visible, and multibyte characters are marked to help you spot mistakes. TurtleEdit warns you about spaces in filenames and prompts you to save before compiling.
Learn with the language you choose.
Configure commands for C, Python, Ruby, and other languages. Practice searching, replacing, and filtering text with regular expressions.

FROM THE CLASSROOM
It began with everyday
stumbling blocks in class.
Compiling before saving. Working in the wrong folder. Overlooking a full-width space in the code. TurtleEdit grew out of a desire to help students avoid these common stumbling blocks in university programming classes.
Read the story
TurtleEdit was written for introductory programming courses at Tohoku University. Its simple interface helps beginners focus on their code. Line numbers, marked multibyte characters, filename checks, reminders to save before compiling, and a button to check the working directory help students avoid common mistakes.
The editor was written in Java using NetBeans. Teachers and learners familiar with these tools can modify it to suit their needs.
