WAT

This boilerplate / starter should help you to replace a bash script as fast as possible - run ./create-my-project.sh and start right away with your business logic.

It should be transparent, you should be able to understand what is happening and go as deep into the matter as you like. It should be easy to understand, all implementations in cmd/ are small and specific so you can junk them together and chain them.

It should help you

• get the job done. Period. (not teach you go concepts all over the place)
• be documented .. right.
• handling script parameters and options using the cobra lib
• running cli commands on the shell with proper stdin/stdout/err handling easily: go-exec
• running cli commands over ssh utilizing your ssh-agent/privkey/password easily: go-sshclient
• transferring files from and to remote server using scp easily: go-sshclient
• Include IntelliJ run configuration to run/debug the tasks right away

Why not learning all the deeper concepts? Well you could .. but that stops most people from using golang over bash in the smaller, daily projects. So you will learn the deeper parts every time you write something, part by part - but that happens as a side-track, while you actually get your job done

Get started

You can generate a new project for yourself using this boilerplate

This will generate a new shell-project with the name 'mycliname' in /tmp/mycliname - you can open the folder using your IDE and start developing right away

./create-my-project.sh --project=mycliname --username=ghusername --strip-ssh

# or with private SCM
./create-my-project.sh --project=mycliname --username=ghusername  --host=ourprivate-scm.tld --strip-ssh

You most probably want to mv the project from /tmp into a folder for your scm prjects.

Parameters

• --project - The name of your CLI program that you are planning (mycliname in the examples).
• --username - Your namespace, usually your GitHub username (ghusername in the examples).
• --strip-ssh (optional) - Will remove the ssh and scp examples from the starter, including all of it's dependencies for a slim and stripped down project.
• --host (optional) - Your private VCS domain (without scheme).

That's it, read the shell output and you are ready and set to start creating.

Included examples

I did ship dist/mycli* in the repo for convenience reasons for now, so you do neither need to build yourself nor us curl Generally depending on your use, use mycli-macos or mycli-linux

Exec

  dist/mycli-macos myexec --cmd="echo hi"

SSH

If you want to the the ssh command, just use the local docker-compose.yml to start a local ssh node

  docker-compose up -d
  dist/mycli-macos myssh --host=localhost --port=2301 --key=test/sshkeys/id_rsa

SCP

If you want to the the ssh command, just use the local docker-compose.yml to start a local ssh node

  docker-compose up -d
  dist/mycli-macos myscp --host=localhost --port=2301 --key=test/sshkeys/id_rsa --file=test/dummytestfile

Build this project yourself

   make build
