Emacs Lisp Code Debugger Link to this section #
Emacs Lisp Code Debugger is an essential tool for developers working with Emacs, enabling efficient troubleshooting and optimization of Lisp code. This tool provides a robust environment for debugging, ensuring seamless code execution and error management.
Key Features Link to this section #
Interactive Debugging: Pause execution at breakpoints, inspect variables, and step through code line by line. This facilitates a deeper understanding of code behavior and logic errors.
Backtrace Analysis: Quickly identify the source of errors with detailed backtraces. This feature allows you to trace function calls and pinpoint where your code deviates from expected behavior.
Conditional Breakpoints: Set conditions for breakpoints to halt execution only when specific conditions are met. This allows for targeted debugging without unnecessary interruptions.
Integration with Emacs: Seamlessly integrates with the existing Emacs environment, leveraging its powerful text-editing capabilities for streamlined development and debugging workflows.
Usage Link to this section #
To activate the Emacs Lisp debugger, add the following line to your Emacs configuration:
(setq debug-on-error t)
Use the following commands for effective debugging:
M-x debug-on-entry: Activate debugging for a specific function.M-x debug: Manually invoke the debugger at a specific point in your code.

Emacs Lisp Code Debugger is a vital tool, empowering developers to write more reliable and efficient code. Its integration with Emacs ensures a cohesive and productive development experience.
Frequently Asked Questions
How do I start the Emacs Lisp debugger?
To start the Emacs Lisp debugger, you can use the `M-x edebug-defun` command while your cursor is on the function you want to debug. This will instrument the function for debugging, allowing you to step through the code execution.
What are the basic commands for stepping through code in the Emacs Lisp debugger?
In the Emacs Lisp debugger, you can use several commands to step through code: `SPC` to step through the next expression, `n` to step over an expression, `c` to continue execution until the next breakpoint, and `q` to quit the debugger.
How can I set breakpoints in Emacs Lisp code?
You can set breakpoints in Emacs Lisp code by placing `M-x edebug-set-breakpoint` on the line where you want execution to pause. Alternatively, you can add `(debug)` to your code, which will trigger the debugger when reached.
