D Issue List

This is a list of issues I encounter when working with the D programming language, and which I find annoying or which limit what I can do with D.

The selection of these issues is completely subjective, I keep it here for personal reference and possibly for others who might want to fix one of these problems or just want to know about the problems I see with D.

Despite all of the issues, I think D is a useful language, otherwise I wouldn't use it and put effort

GPG - SSH setup

Generating the master key

Here we create the master key. We want only Certify capability: we use the master key only to create the subkeys, Sign - Encrypt - Authenticate capabilities will be assigned to the subkeys.

Run the following command to start the master key generation process. Select the set your own capabilities creation process (type 8)

GPG + Git SSH Authentication and Signing on Windows 10

Introduction

This simple Gist will explain how to settup your GPG key to work for SSH authentication (with Git) and Git commit signing on Windows 10. This may seem straightforward on Linux, but there are certain tweaks needed on Windows.

No Cygwin, no MinGW, no Git Bash or any other Linux emulated environment. This works in pure Windows 10.

Software needed

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

	# Very fast __git_ps1 implementation
	# Inspired by https://gist.github.com/wolever/6525437
	# Mainly this is useful for Windows users stuck on msys, cygwin, or slower wsl 1.0 because git/fs operations are just slower
	# Caching can be added by using export but PROMPT_COMMAND is necessary since $() is a subshell and cannot modify parent state.
	# Linux: time __ps1_ps1 (~7ms)
