Docs

Usage:

terminal-animator -h

Usage of terminal-animator:
  -config string
        Configuration file path for animation

Example:

terminal-animator -config demo-animation-108.yaml

Configuration documentation

Terminal Animator is configured by specifying a list of animation files:

animationFiles:
  - demo-animation-width-108/001-boot.yaml
  - demo-animation-width-108/002-boot.yaml
  - demo-animation-width-108/003-load.yaml
  - demo-animation-width-108/004-welcome.yaml
  - (...)

Each file describes the animation type and additional settings for that animation

Animation files - supported fields:

• directives (map[string]any): Defines type and animation settings, see below
• frames ([]string): List of text frames of the animation

Directives:

• type (string): Animation type, currently supported animations: clear-line, clear-screen, loop, printer, typewriter
  • clear-line: Animation that renders frames a on single line, clearing any previous frame
  • clear-screen: Animation that redraws whole screen, clearing whole screen before each frame
  • loop: Animation that loops specified amount of times after rendering all frames
  • printer: Animation that renders each frame line by line, split by newline - \n
  • typewriter: Typewriter animation effect, either by character or by word
• maxDelay (float32): Random delay duration between rendering frames. Default 0.5
• evenDelay (bool): Whether delay between rendering frames should be even
• endNewLines (int): Number of newlines to add after that particular animation
• loop (int): Number of how many times the animation will be repeated. Only applicable to loop animation
• word (bool): For typewriter animation, whether to split animation frame by word or by character (default)
