New on CTAN: boolalg
Initial release (v1.0.0) of the boolalg package. Features: - Pure-TeX recursive-descent parser supporting algebraic, programmatic, and LaTeX math notations for Boolean expressions (AND, OR, NOT, NAND, NOR, XOR, XNOR). - Automatic truth table generation (\btable, \btable*) with intermediate sub-expression columns and automatic width fallback. - Step-by-step Boolean expression simplification (\bsimplify, \bsimplify*) with explicit law justifications (including Absorption and the Consensus theorem). - Bidirectional algebraic equivalence prover (\bprove) with automatic counterexample search when two expressions are not equivalent.

Thanks for the upload. For the CTAN Team Erik Braun CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs .
Boolalg – Truth tables, step-by-step simplification, and algebraic proofs for Boolean
The boolalg package provides pure-TeX macros for parsing, evaluating, simplifying, and proving Boolean algebra expressions without requiring external tools, Python, or shell-escape:
– \btable and \btable*: Generate truth tables with intermediate subexpression columns and optional simplified results. – \bsimplify and \bsimplify*: Perform step-by-step algebraic simplification with explicit law justifications (Idempotence, Absorption, Consensus theorem, De Morgan’s laws, Distributivity, etc.). – \bprove: Construct step-by-step algebraic proofs between two equivalent expressions, or automatically find and print a concrete counterexample if the claim is false.
Expressions support flexible input syntax including implicit multiplication (AB), postfix primes (A'), prefix operators (!, ~), English words (and, or, xor, nand, nor, xnor, not), and standard LaTeX math symbols (\land, \lor, \oplus, \lnot, etc.).
