Adding dot-repeat to your Neovim plugin

In Neovim, the . character repeats "the most recent action"; however, this is not always respected by plugin actions. Here we will explore how to build dot-repeat support directly into your plugin, bypassing the requirement of dependencies like repeat.vim.

The Basics

When some buffer-modifying action is performed, Neovim implicitly remembers the operator (e.g. d), motion (e.g. iw), and some other miscellaneous information. When the dot-repeat command is called, Neovim repeats that operator-motion combination. For example, if we type ci"text<Esc>, then we replace the inner contents of some double quotes with text, i.e. "hello world" → "text". Dot-repeating from here will do the same, i.e. "more samples" → "text".

Using `operatorfunc`

By default, PyTorch team doesn't release packages for ARM architecture. Luckily, someone is supplying unofficial builds (hats off to this person!).

Fast.ai also has a problem: it depends on spaCy, which also doesn't want to build on ARM by default. I'm not going to do NLP, so will install fast.ai without spaCy.

PyTorch

I initially tried using ARM builds from here:

Download HumbleBundle books

This is a quick Python script I wrote to download HumbleBundle books in batch. I bought the amazing Machine Learning by O'Reilly bundle. There were 15 books to download, with 3 different file formats per book. So I scratched a quick script to download all of them in batch.

(Final Result: books downloaded)

	#!/usr/bin/env lua5.1

	-- assocation list on the command line
	--
	-- rep is: key1 val1 key2 val2 ...
	--

	local function succeed(s)
	if s ~= true then
	io.stdout:write(s, '\n')

	function fish_load_sudo_alias
	function sudo
	if functions -q -- "$argv[1]"
	# Create a string which quotes each of the original arguments
	# so that they can be safely passed into the new fish
	# instance that is called by sudo.
	set cmdline (
	for arg in $argv
	printf "\"%s\" " $arg
	end

	# Based on https://gist.github.com/bastibe/c0950e463ffdfdfada7adf149ae77c6f
	# Changes:
	# * Instead of overriding cd, we detect directory change. This allows the script to work
	# for other means of cd, such as z.
	# * Update syntax to work with new versions of fish.
	# * Handle virtualenvs that are not located in the root of a git directory.

	function __auto_source_venv --on-variable PWD --description "Activate/Deactivate virtualenv on directory change"

	set cmd (commandline -cp)
	bash -c "source get-bash-completions.sh; get_completions '$cmd'"
	end

	# Set the tool to use bash completions
