While procrastinating about setting up this blog I wanted to create a favicon in a pixel art style. Instead of creating the icon I got carried away spaghetti coding a pixel art editor for the terminal in PowerShell…

To open the editor run ./PwshEditor.ps1
For those who like vim run ./SpriteEditor.ps1 -AppSettingsPath “appsettings.vim.json”
The editor controls are all indicated in the UI apart from pressing [SPACE] to draw pixels and arrow keys to move.
Snake mode will make the pen or eraser constantly apply changes as you navigate the canvas.

To open the viewer run ./PwshViewer.ps1
This will start a PowerShell web server and open a page showing all of the images in the sprites folder. There is a problem with ctrl-c being caught in the terminal so sometimes you need to close the window to stop the web server. I think using a background job would stop this occurring but I haven’t tried it yet.
