Bit Peek for Visual Studio Code

Bit Peek can display the binary and other forms (hexadecimal, octal, ASCII) of numbers at mouse cursor in a very easy to read format. Extension is available on the Marketplace.

Features

By default, Bit Peek will show bits in an unique "register friendly" mode: all the 0s will be displayed as ., so you can identify the 1s at a glance.

Both the bit representation and numbering style are customizable:

• bit-peek.registerView can switch the 0 style between register friendly and ordinary mode.
• bit-peek.msb0 can switch the bit numbering between LSB0 (default) and MSB0 (Motorola style).

Bit Peek will try to identify the base of numbers automatically. But if you are analyzing memory dumps, try Bit Peek: Toggle force HEX mode command to enforce parsing as hexadecimals:

For octal numbers, Bit Peek will interpret the bits as UNIX file permission when possible:

Supported Formats

Limitations

• For the decimal numbers without base prefix and postfix, it must not begin with 0, or it will be recognized as octal (C/C++ rule).
• In some languages (C/C++/JavaScript...), the sign of decimal numbers cannot be fetched due to the limitation of Visual Studio Code, so it cannot recognize negative numbers in such case.
