I wrote this shell as a part of a job interview. I spent so much time on this sucker I felt I had to release it.
I didn't end up getting the job, this shell failed in a few areas. I attribute that to the fact that I had a week to build it and drastically underestimated the difficulty of certain sections of the program. As a result, half of this shell is over-engineered, the other half is a mess.
I'll leave it to the reader to determine which half is the mess ;)
Provided is a Makefile and a Dockerfile. You can build this project simply by running
make dev-machine
docker exec -it dev-machine make
This will produce a binary that should be able to run on any Linux/amd64 OS. This is because I built against musl. I have beef with glibc.
Again, this will run on any Linux machine, but for the example here is how you run it within a container:
docker exec -it dev-machine output/esh
FYI, output should also be a volumed directory in the sourcedir, so you can run it locally as well if you like:
./output/esh
I wrote some tests for my tokenizer. Feel free to take a look under the test/ directory.
Additionally you can run them using:
make unit-test
