Project Description

Xalc is a hexadecimal calculator for embedded systems programmers, implemented as a pre-processor for Python expressions, with a console interface based on IPython.

Features:

  • Mixed calculations with hex, decimal, binary and binary prefix literals
  • Support for undecorated hex literals. Ambiguous literals can be forced to hex by either prefixing or suffixing with ‘x’.
  • Display in hex, decimal, 32-bit binary (with bit position ruler) and binary prefixes (sizes)
  • Simple bit mask construction
  • Bit field extraction operator
  • Highlighting of changed nibbles/bits
  • From IPython: Support for arbitrary Python expressions (minus the ones that conflict with the pre-processed syntax), command history, access to previous results with _* variables, etc.

The following “screenshot” demonstrates some of the features of Xalc. The real program displays the different bases in different colors, if your console supports that:
