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

Extending python-docx

Background

I was recently tasked with scraping data from a few thousand of word documents each of which contained nested docx documents which were referenced by w:altChunk elements in the body of the main ./word/document.xml file, like so:

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator

Exposing a directory on the host machine to an LXC container

1. Log into the container and create an empty directory, this will be the mount point
2. Log out and stop the container.
3. Open to your container's config file
   • For regular LXC containers: /var/lib/lxc/mycontainer/config
   • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
   • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0

• Both of these paths are relative to the host machine.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

# DESCRIPTION:
#
#   Set the bash prompt according to:
#    * the active virtualenv
#    * the branch of the current git/mercurial repository
#    * the return value of the previous command
#    * the fact you just came from Windows and are used to having newlines in
#      your prompts.
