Vim Script for Python Developers

This is a guide to Vim Script development for Python developers. Sample code for the various expressions, statements, functions and programming constructs is shown in both Python and Vim Script. This is not intended to be a tutorial for developing Vim scripts. It is assumed that the reader is familiar with Python programming.

For an introduction to Vim Script development, refer to usr_41.txt, eval.txt and Learn Vimscript the Hard Way

For a guide similar to this one for JavaScript developers, refer to Vim Script for the JavaScripter

This guide only describes the programming constructs that are present in both Python and Vim. The constructs that are unique to Vim (e.g. autocommands, [key-mapping](https://vimhelp.org/map.txt.html#key-m

MAGIC aka Making Anything Gruelingly "Impossible" Coherent

Whatever operating system you are using to create the USB, you will need to have a Windows 10 ISO, either from Microsoft or your system manufacturer and have a USB drive 8GB or larger (or one with at least 5GB of free space and using the FAT32 filesystem, but using a fresh and empty one is best).

TL;DR

#macOS/Linux
# First try the `bootiso` program, it has options for splitting the WIM for you!
# https://jsamr.github.io/bootiso/
# You need to already have 7zip aka `p7zip` on macOS and Linux, and `wimlib` macOS via `brew` or `wimtools` on Linux

Install rust

jail-app is name of jail.
```
$ jexec jail-app
$ pkg install curl
```
Download and install rustup
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Using cec-client on a Raspberry Pi

Most modern HDMI connected devices support Consumer Electronics Control (CEC). It allows devices to send commands to each other, typically to get the TV to switch input and control volume. If you have ever turned on a Game Console and had your TV automatically change input to that device you have seen CEC in action. It is very convenient and useful, sort of a universal remote that works.

Every manufacturer seems to have it’s own branding of CEC (e.g. Samsung Anynet+, LG SimpLink, Sharp Aquos Link) but it may need to be enabled. Check your manual for details.

Using a Raspberry Pi connected to a TV that supports CEC, you can use the command line cec-client application to control the inputs and the TV itself. These are notes on how to use cec-client and understand the different options.

Quick Terraform script to deploy Gitlab runner with docker onto Hetzner Cloud (Hcloud)

Create other terraform stuff

tf-backend,
creds.auto.tfvars with hcloud_token
ssh key: mkdir keys; ssh-keygen -f id_rsa

modify cloudinit.yml:

change gitlab url
ADD_YOUR_REGISTRY_TOKEN -> Set to the Gitlab Runner Registration Token
Add more allowed images/services, if using gitlab registry, like that: registry.myinstance.com/administrators/docker-images/*, change base image etc.

Forwarding SSH agent

Configure ~/.ssh/config

# Allow Agent forwarding for a specific host (by security)
Host remotehost
