This program is the helper used to create the gifs in the README. What follows are notes for when I do this in the future.

Overview

The software in this demo folder is used to demonstrate all of the spinners that exist, and to help generate the GIFs used for the README.md file in the root of this repo.

There are two helper scripts in the scripts/ folder. ffmpeg.sh helps with converting the h.264 .mp4 files into .gif files. The rename.go program then helps rename those .gif files into the right name for committing to the repository.

The GIFs are stored in a sister GitHub repository, github.com/theckman/yacspin-gifs to avoid cluttering up this repo with binary files (images).

Checklist

• start a screen recording of the terminal using Apple QuickTime Player
• start the demo program (main.go) and let it run entirely before stopping the QuickTime recording
• load the .mov file into Adobe Preimere, and cut the clip down into the individual 10 second clips of each spinner
• turn the clips in the original Sequence into Subsequences
• use media encoder to export those subsequences to their own files, matching source with Adaptive High Bitrate
• use the scripts/ffmpeg.sh script to convert the .mp4 files into .gif files
• go run the scripts/rename.go program, to rename the .gif files to match the names we expect

QuickTime Capture Sizes

When using the Apple QuickTime Player to capture the screen recording, you can have it only capture a specific area of the screen. These are the capture sizes I played with on my Apple 16" M1 Max MBP laptop.

Please note, that the video files rendered from these captures tend to have about 2x the resolution. Keep that in mind when deciding how large of an area you want to capture.

Capture Size (pixels)	Font Size
650w x 24h	18
340w x 12h	10
1300w x 47h	38
