Optimize Debugging with Crystal Code Debugger Tool

Crystal Code Debugger Link to this section #

The Crystal Code Debugger is an essential tool for developers working with the Crystal programming language. It facilitates efficient debugging by providing a robust environment for identifying and fixing code issues. This guide will cover core functionalities and usage tips to enhance your development experience.

Key Features Link to this section #

• Breakpoint Management: Set and manage breakpoints easily to pause execution and inspect variable values.
• Step Execution: Navigate through your code line by line with commands like step, next, and continue.
• Variable Inspection: Examine variable states at any point in your code to understand how data is being manipulated.

Using the Crystal Code Debugger Link to this section #

To start debugging, you need to compile your Crystal code with debugging information enabled:

crystal build your_program.cr --debug

Launch the debugger:

gdb your_program

Once inside GDB, you can use various commands to control the execution:

• Setting Breakpoints:

  (gdb) break line_number
  

  Replace line_number with the line you want to pause execution.

• Running the Program:

  (gdb) run
  

• Inspecting Variables:

  (gdb) print variable_name
  

  This command displays the current value of variable_name.

Best Practices Link to this section #

• Consistent Naming: Use clear, descriptive names for variables to simplify debugging.
• Code Comments: Keep your code well-documented to make tracing logic easier.
• Version Control: Regularly commit changes to minimize the risk of losing track of what modifications might have introduced bugs.
