Go Koans

This repo is forked from cdarwin/go-koans. I am adding the solutions in an encrypted form (<filename>_solution.gpg) so I can still access the solutions at a later date and don't spoil the fun for others. Cheers!

Steps to access solutions

Warning: These steps won't work for you, because you don't have my GPG key :stuck_out_tongue:. They're just for me in the future if I want to access the solutions

1. Encrypt

gpg --output about_<name>_solution.gpg --encrypt --armor --recipient mbtamuli@gmail.com about_<name>.go

2. Decrypt

gpg --output about_<name>.go --decrypt about_<name>_solution.gpg

Bash fu

Since I love bash and am lazy enough to not want to repeat uninteresting stuff , here are a few points related to solving these koans.

1. I was having to run go test every time I made the changes, so I made the command run every time I saved the file

git clone https://github.com/mbtamuli/go-koans/ && cd $_
while true; do
  inotifywait -qe modify,create,delete -r $PWD -o /dev/null &&\
  clear && \
  docker run --rm -ti -v "$PWD":/go/src/ -w /go/src/ golang:1.11-alpine go test
done

2. Trying to access the solution or encrypting the solution, you'll have to run the encrypt or the decrypt steps for each and every file, but not if you do this

# Encrypt
for file in ./*.go; do
 if [[ $file != *"setup_koans_test"* ]] && gpg --output "${file%%.go}_solution.gpg" --encrypt --armor --recipient mbtamuli@gmail.com "$file"
done

# Decrypt
for file in ./*.gpg; do
 gpg --batch --yes --output "${file%%_solution.gpg}.go" --decrypt "$file"
done
