dnSpyEx vs Perl Debugger

dnSpyEx is an unofficial continuation of dnSpy, a debugger and .NET assembly editor for working with assemblies without source code. It can debug .NET Framework, .NET, and Unity game assemblies, with breakpoints, tracepoints, conditional breakpoints, exception breakpoints, and multiple-process debugging. Editing covers metadata and methods or classes in C# and Visual Basic, plus low-level IL method bodies. The project lists C# and Visual Basic decompilers using the ILSpy engine, along with a BAML decompiler and disassembler. Assembly search, class and method usage analysis, caller finding, bookmarks, and project export are also included. A public API supports extensions, and the C# Interactive window can control or script dnSpyEx. The latest stable release listed is v6.6.0, which adds a .NET 10 distribution. It is free under GPLv3. Release notes describe Wine compatibility adjustments for Linux, not native Linux support. Dynamic methods cannot be debugged because of CLR limitations.

Perl Debugger is an interactive debugger included with Perl, not a separate program. Running Perl with the `-d` flag loads the debugger and adds source information, allowing users to inspect code, set breakpoints, view stack backtraces, and change variable values. The program must compile correctly before debugging.

Debugger commands support stepping into subroutine calls, stepping over them, and tracing execution. Conditional breakpoints and watches on global expressions can pause a run when specified conditions or changes occur. The `x` command can pretty-print nested data; displaying lexical variables requires PadWalker version 0.08 or higher. Options can be set interactively, through `PERLDB_OPTS`, or in `.perldb` files. Documentation also describes a GUI option through Devel::ptkdb. The debugger does not provide stack-frame information for functions not compiled by Perl, such as C or C++ extension functions, and compile-time executable statements are not stopped, though some can be traced with AutoTrace. Perl is listed for Linux, macOS, and Windows, and the debugger is free.
