Yanking and pasting works seemlessly between Neovim’s regular buffers and terminal buffers. In this video, we’ll look at how the Normal mode paste command works in a terminal buffer, and we’ll create a mapping to help with pasting text directly from Terminal mode.

Pasting into a terminal buffer

Neovim lets us create mappings using the meta key. In this video, we’ll set up some mappings to make it easier to exit from Terminal mode. We’ll also set up mappings using the meta key with h, j, k, and l to switch between split windows.

Creating mappings for :terminal

Neovim lets you run a terminal emulator inside of a buffer. In this video, we’ll cover some of the basics of how terminal buffers work, and how you can use them alongside regular buffers in your workflow.

This video covers a couple of small but delightful Neovim features. You’ll see how to make Neovim show a live preview of how the substitute command will change our document. And you’ll find out how to make the yank operation highlight the range of text that it copied.

Neovim’s :checkhealth command can diagnose problems with your configuration. In this video, we’ll run this command and follow its suggestions to enable features such as python integration and ruby integration.

In this video, we’ll see how to install and set up Neovim so that it reuses your existing Vim configuration files. Most plugins should work in Neovim just like they do in Vim.

Minpac is a minimal package manager for Vim 8. It makes it easy to add plugins, keep them up to date, and remove them. In this video, we’ll see how it works.

Packages are a new feature in version 8 of Vim. In this video, we’ll see how we can use packages to easily install Vim plugins. The process will be familiar if you’ve used pathogen.

Installing plugins using packages

When UltiSnips is triggered from Visual mode it captures the selection and makes it available to our snippets. We can then insert the selection unchanged with the $VISUAL placeholder, or we can use UltiSnips Python interpolation to transform the text before inserting it back into the document.

Using selected text in UltiSnips snippets

UltiSnips can execute Python code and interpolate the result into a snippet. This makes it possible to create snippets that react to the text entered in each field. We’ll look at an example that performs a simple calculation and inserts the result into our document.

Using Python interpolation in UltiSnips snippets

Snippets allow you to quickly insert predefined chunks of text into your document. The feature as I know it was first introduced in TextMate, but it has since been emulated by many other editors. For Vim users who want this functionality, the UltiSnips plugin is a great choice. Let’s start by looking at the basics.

Swapping two regions of text is a common task, which normally requires that we make two separate changes to the document. Tom McDonald’s exchange plugin offers an elegant alternative, by providing an operator that swaps two regions of text in one go.

We can use pandoc as a filter to clean up WYSIWYG-generated HTML. Pandoc is a commandline program, but we can call it from inside Vim either using the bang Ex command, or by configuring the formatprg option to make the gq operator invoke pandoc.

Using external filter commands to reformat HTML

The gn command (introduced in Vim 7.4) makes it easy to operate on regions of text that match the current search pattern. It’s especially useful when used with a regex that matches text regions of variable length.

Lots of Vim’s built-in Normal mode commands can be executed multiple times by prefixing them with a count. User-defined Normal mode mappings don’t usually handle counts the way we might like them to. We’ll explore a couple of techniques for making our custom mappings respond predictably to a count.
