Navigating the modes of Vim

This diagram illustrates navigating through Vim’s modes. It was built factoring Vim 9 (i.e., all its modes, including up to two new modes, cr and cvr, in November 2023). Information about the state() and 'showmode' is provided too.

SVG version

Some features are only available in the SVG version. It is not provided directly from within this gist’s files because SVGs do not always play nicely in GitHub (particularly, refusing to display embedded fonts).

The SVG version includes hover text help, which shows pertinent information about the underlying key, command, mode, etc.

Connect host and VM when using a MACVTAP interface

NB: The following is only of interest if you want to share the host network with your virtual machine. The most common way this gets implemented is by setting up a bridge which includes the physical interface. Using a [MACVTAP] inerface is suposed to be more efficient, since it avoids the additional bridge in the network setup.

In this gist, we extend the information provided in the documenation on linux virtual interfaces.

In the following, we assume you host interface is eth0. IP addresses used:

• host: 198.51.100.50/24
• virtual machine: 198.51.100.198/24
• default gateway: 198.51.100.254

Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

            "background" : "#1d2021",
            "black" : "#665C54",
            "blue" : "#7DAEA3",
            "brightBlack" : "#928374",
            "brightBlue" : "#7DAEA3",
            "brightCyan" : "#89B482",
            "brightGreen" : "#A9B665",
            "brightPurple" : "#D3869B",
            "brightRed" : "#EA6962",

Seamlessly editing remote files in (Neo)Vim with Netrw and scp

Neovim and Vim both come bundled with a standard plugin called Netrw. Netrw acts a file explorer (similar to NERDTree), but more importantly has the ability to work with scp (as well as sftp, rcp, ftp, and lots of others :h netrw-nread) to let you edit files and browse directories that are hosted on a remote machine, inside of your local Vim instance.

This is useful since you are able to use your Vim setup and plugins without copying over your dotfiles to the remote machine. As well, since the file is copied to your local machine, there will be no delay when typing.

Setup

This is optional for Vim, but required for Neovim (check this Neovim issue explaining why).
