Jetpack Compose — Basic Composable
Compose is Android's modern declarative UI toolkit. A `@Composable` function describes UI; the runtime re-runs it when inputs change. Replaces XML layouts entirely.

JavaScript
Animate Counter (Number Roll-Up)
Smoothly animates a number from a start value to an end value over a given duration using requestAnimationFrame. Supports a custom easing function (defaults to ease-out quad). Ideal for dashboard stat widgets, donation counters, and any UI where a bare static number would be less impactful.
Bash
Spinner During Long Task
Show a rotating spinner next to a status message while a background command runs. Cosmetic but vastly improves the user experience of long scripts.
Bash
Read Single Keystroke Without Enter
For menus and confirm prompts where you want one-key response (no need to press Enter). -n 1 reads exactly one character, -s silences the echo.
Bash
ANSI Color Output Helpers
Wrap printf with ANSI escape codes for color and bold. Auto-disable if stdout isn't a TTY (so piping to a file doesn't pollute it with escape sequences).
Bash
Print a Boxed Banner
Wrap a string in a Unicode box for important headers. Auto-sizes to the longest line. Helps milestone messages stand out in long CI logs.
Bash
Confirm Prompt (y/n)
A reusable yes/no prompt with a configurable default and a single-keystroke read. Returns 0 for yes, non-zero for no.
JavaScript
Generate Initials Avatar (Canvas)
Draws a coloured circular avatar with up to two initials on an HTML5 Canvas and returns it as a data URL. Generates a consistent background colour from the name string so the same user always gets the same colour. Useful as a fallback when a user has no profile photo.
Bash
Pretty-Print Last Exit Code
A tiny prompt-trick that shows the previous command's exit code in red when it failed. Stops you from missing silent errors in long terminal sessions.
Bash
Progress Bar (basic)
Draw a single-line progress bar that updates in place. Useful for batch jobs where you know the total work count up front.
JavaScript
Keyboard Shortcut Manager
Registers global keyboard shortcuts with a simple key-combo syntax ("ctrl+k", "meta+shift+p"). Handles modifier keys (ctrl, alt, shift, meta) and prevents default browser behaviour when a shortcut matches. Shortcuts can be unregistered individually or all at once, making it easy to scope shortcuts to page sections or modals.
