# elfReader 🧝
A Swift based [ELF](https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) parser. Written after reading [`Life of a binary`](https://kishuagarwal.github.io/life-of-a-binary.html), see below.
### Build
```shell
swift build
```
### Test
```shell
swift test
```
### Life of a Binary
```shell
docker run -it --rm -v $(pwd)/elf-reader:/elf-reader --workdir /elf-reader/Tests/Resources ubuntu:bionic
# install gcc and readelf
apt update && apt upgrade -y && apt install -y gcc elfutils
gcc --version
-> gcc (Ubuntu 7.4.0-1ubuntu1~18.04) 7.4.0
# sample.c is provided, so just compile.
gcc -c sample.c
eu-readelf -h sample.o
-> ELF Header:
Magic: 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00
Class: ELF64
Section header string table index: 12
```
At this point, you could jump out of the container, and run `swift test`.
A basic test for `elfReader` will look at the `sample.o` we just compiled and dump some ELF header info as part of the output.
```shell
pushd elf-reader
swift test
```
```swift
some: elfReader.elfReader
- magic: "7F 45 4C 46 02 01 01 00 00 00 00 00 00 00 00 00"
- architecture: elfReader.elfReader.Architecture.elf64
- endianess: elfReader.elfReader.Endianess.littleEndian

- machine: elfReader.elfReader.InstructionSet.EM_X86_64
