Tama・玉
A clickable binary bit editor.
Type a number — decimal, 0x1B44, 0b1010, or
0o755 — and it becomes a register you can flip bit by bit.
Label its bit ranges with a reusable, color-coded format:
numeric fields, per-bit flags (r-x), or an enum that decodes
a value to a name. Build one visually and it's yours.
What it does
Tama (玉, the abacus bead) is a standalone bit editor — the same component that ships inside Soroban's programmer mode, here as a front-end-only app. Click bits to stage a value, pick a width from 8 to 256 bits, and read it back in decimal and hex. Use copies the value to your clipboard.
Formats
A format turns the flat register into a labeled diagram. Six presets ship in, or carve your own with the visual builder — claim a run of bits, name it, pick its kind (numeric, flags, or enum), color it, and save. Saved formats persist in your browser.
