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.

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.
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.
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
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
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
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
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.
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.
