Editing files in Vagrant using your local copy of Atom

In case you want to have an IDE locally, but have your Development environment be on a VM

Install Atom on your local (host) machine: https://atom.io/
Install the "remote-sync" package: https://atom.io/packages/remote-sync
Ensure Vagrant is running (e.g. vagrant up)
Create an empty directory on your local (host) machine that you want to "sync" with a directory on the Vagrant VM
Open that empty directory in Atom
Right click on it, select "Remote Sync -> Configure"
Fill in the SSH configuration details
- Hint, run vagrant ssh-config to get these details for a Vagrant VM
- You can test them by trying: ssh -p [port] -i [identityfile] [user]@[hostname]
- For the remote folder, you can use a relative path (based on user's home directory)
Right click on the empty folder again, select "Remote Sync -> Download Folder". Wait while it syncs your remote folder down to the host.
Edit the files. If you have it upload on save (see configuration of "remote-sync"), then saving will upload the changes to Vagrant.
- Otherwise, you can "Remote Sync -> Upload File" by right clicking on the individual file
- You can also "Monitor File" for remote changes (to sync down to your local machine when changed remotely)

Atom + Rubocop on Windows

This is useful for Ruby coding in Atom on Windows. You do however have to install Ruby and Rubocop on Windows.

Install Ruby on Windows per https://rubyinstaller.org/
Install Ruby DevTools per https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
Install Rubocop
- gem install rubocop --platform=ruby
- gem install rubocop-rspec --platform=ruby
Test it to ensure it's working:
- rubocop [path-to-an-rb-file]
In Atom, install Linter and Linter-Rubocop
- You may need to configure linter-rubocop to use the full path of your rubocop install (find it using which rubocop)
That's it! Now anytime you open or edit a Ruby file, you'll get warnings if you disobey rubocop's suggestions!
