What's this?

Instructions to obtain ZSH on a windows environment, without the input funny business presented by some other attempted solutions.

The final result is ZSH running on a mintty terminal, emulated by cygwin, and being handled by the popular cmder.

Why is this here?

For the benefit of myself and others. I've already followed these instructions twice. It took me hours to figure all this out, maybe someone else can save a few.

What exactly is covered?

• Installing and setting up cmder

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

How to get @DevBlackOps Terminal-Icons module working in PowerShell on Windows

Note: since version 0.1.1 of the module this now works in Windows PowerShell or PowerShell Core.

1. Download and install this version of Literation Mono Nerd Font which has been specifically fixed to be recognised as monospace on Windows:

I recently switched over to neovim (see my screenshots at the bottom). Below is my updated config file.

It's currently synchronized with my .vimrc config except for a block of neovim-specific terminal key mappings.

This is still a work in progress (everyone's own config is always a labor of love), but I'm already extremely pleased with how well this is working for me with neovim. While terminal mode isn't enough to make me stop using tmux, it is quite good and I like having it since it simplifies my documentation workflow for yanking terminal output to paste in a markdown buffer.

These days I primarily develop in Go. I'm super thrilled and grateful for fatih/vim-go,

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

• Plain ASCII
• ANSI escape codes: 16 color codes with bold/italic and background
• 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
• 24-bit true color: "888" colors (aka 16 milion)
