# libgoblin [](https://travis-ci.org/m4b/goblin)
### Features
* goblins (TBA)
* the best, most feature complete ELF64/32 implementation, ever - now with auto type punning!
* many cfg options - it will make your head spin, and make you angry when reading the source!
* slowly adding mach-o and PE binary support, mostly because it's boring and it's just a port of [rdr](http://github.com/m4b/rdr)
* tests
* awesome crate name
`libgoblin` aims to be your one-stop shop for binary parsing, loading,
and analysis. Eventually, at some future date, once the holy trinity
is finished (ELF, mach, PE), writers for the various binary
formats are planned.
### Use-cases and Planned Features
Here are some things you could do with this crate (or help to implement so they could be done):
1. write a compiler and use it to generate binaries with the future writers defined here
2. write a binary analysis tool which parses all three formats
3. write a [non-functioning dynamic linker](http://github.com/m4b/dryad) because libc implementations define massive, persistent global state and are tightly coupled with their dynamic linker implementations, because *nix is broken by design ;)
4. write a kernel and load binaries using the forthcoming "pure" cfg. I.e., it is essentially just struct and const defs (like a C header) - no fd, no output, no std.
5. write a bin2json tool (http://github.com/m4b/bin2json), because why shouldn't binary formats be in JSON?
### Cfgs
`libgoblin` is designed to be massively configurable. The current flags are:
* elf64 - usable
* elf32 - usable
* mach64 - wip
* mach32 - wip
* pe64 - unimplemented
* pe32 - unimplemented
* endian_fd - parses according to the endianness in the binary
* std - to allow `no_std` environments
