My vim/nvim secret sauce

Here is an overview of some of the core customizations I have built for my own vim/nvim setup over the years. Sometimes I try to explain and share to friends and people online, but it's very difficult to summarize what they are, so I am collecting an overview and code snippets of the current state of my tweaks at the time of writing, here. You can find my full and up to date vim config at my dotfiles repo

Along the way whenever I describe workflows in vim I will highlight the count of keystrokes. In a sort of pragmatic vim golf fashion many of my tweaks are made with an eye toward reducing the number of keystrokes required to achieve a given common task.

This gist is written to address challenges related to copying data out of buffers that you may encounter when using tools in the terminal, in particular in dealing with modern versions of tmux and vim. Care is taken to use these tools with their configuration that is provided out of the box.

Couple of notes:

• All of this applies across Linux and macOS.
• Note that the "copied to clipboard" notification you will see in demos below is being generated by the Clipboard Indicator GNOME extension tool. It is useful to demonstrate as it happens when content is successfully preserved into our system clipboard. It also offers very useful clipboard history management, although many other apps can be used for the same purpose. For example, on macOS, I prefer to use the clipboard manager that is built into BetterTouchTool.

Let us proceed!

Routing tips for VPNs on OS X

When VPNs Just Work™, they're a fantastic way of allowing access to a private network from remote locations. When they don't work it can be an experience in frustration. I've had situations where I can connect to a VPN from my Mac, but various networking situations cause routing conflicts. Here are a couple of cases and how I've been able to get around them.

Specific cases

Case 1: conflicting additional routes.

In this example the VPN we are connecting to has a subnet that does not conflict with our local IP, but has additional routes that conflict in some way with our local network's routing. In my example the remote subnet is 10.0.x.0/24, my local subnet is 10.0.y.0/24, and the conflicting route is 10.0.0.0/8. Without the later route, I can't access all hosts on the VPN without manually adding the route after connecting to the VPN:

        if (mappedObject !== false && Array.isArray(mapped) && mapped.length === 2) {
            if (!mappedObject) {
                mappedObject = { };
            }
            mappedObject[mapped[0]] = mapped[1];
            // always do the work of normal array mapping, I guess
