tl;dr

A fast Rust library for reading DWARF debugging information from compiled binaries, so tools like debuggers and crash analyzers can look up source lines and variable names without copying data around.

what do people make with this?

VIBE 1

Build a custom debugger that reads DWARF data to show source lines and variable names.

VIBE 2

Write a tool like addr2line that maps crash memory addresses back to source code locations.

VIBE 3

Build a profiler or crash analyzer that needs to understand what's in a compiled binary.

VIBE 4

prompts (copy fr)

prompt 1
Show me how to use gimli to parse DWARF sections extracted from an ELF binary with the object crate.
prompt 2
Write a small Rust program using gimli that maps a memory address to a source file and line number.
prompt 3
Explain how gimli avoids copying data when parsing large DWARF sections.
prompt 4
Help me understand how gimli stays neutral about ELF vs Mach-O and what scaffolding I need to add.
prompt 5
Walk me through building a simple crash analyzer on top of gimli.
