My Visual-Studio Code – Cheat Sheet

This is just a short collection of VSCode commands and tricks which I personally did not know after switching from Eclipse ID.

Open Command Palette

Most things in VSCode can be controlled via the Command Palette:

Press Ctrl + Shift + P

Tag and Push

To tag the new release and push the tag to Github open the command palette and use

Git: Create Tag
-> choose your projec
-> enter teh tag name

Next you can push your new local tag to github with the command

Git: Push (Follow Tags)

Clean Java Projects

In some situations it may be helpful to rebuild all Java projects in your workspace

Java: Clean Java Language Server Workspace

SSH Key – Github Pull hangs…

In case you run into a scenario that your build-in git pull command within VSCode hangs forever, this may be an issue related to the ssh-agent (find background here).

You can test if yoru ssh-agent is running (which is necessary for VSCode) by checking the following command in a terminal:

$ ssh-add -l
The agent has no identities.

The result here shows, that not SSH IDs are available and this causes the hang in VSCode.

To solve such a situation, you can open a Terminal and enter

$ eval `ssh-agent`
$ ssh-add

This will promt you for the password of your ssh private key and register the ssh-agent with the SSH id. Now you can start VSCode:

$ code

This way VSCode will inherit the environment variables it needs to get key services from ssh-agent, and therefore will not prompt for your passphrase so long as the ssh-agent process continues running.

To automate this you can add the following script into your ~/.bashrc or ~/.bash_profile file:

if [ -z "$SSH_AUTH_SOCK" ]; then
   # Check for a currently running instance of the agent
   RUNNING_AGENT="`ps -ax | grep 'ssh-agent -s' | grep -v grep | wc -l | tr -d '[:space:]'`"
   if [ "$RUNNING_AGENT" = "0" ]; then
        # Launch a new instance of the agent
        ssh-agent -s &> .ssh/ssh-agent
   fi
   eval `cat .ssh/ssh-agent`
fi
