Nice. You can almost parse the expression with the same technique.
use strict; use warnings; use Data::Dump; my @exprs = ( "Y = A + (B*C)", "Y = A + (B' + (C*D)')", "Y = A*(B*(C'+D)')", ); for my $expr (@exprs) { print "$expr\n"; $expr =~ s/\(/[/g; $expr =~ s/\)/],/g; $expr =~ s/(\w+|[+*'=])/"$1",/g; my @parse = eval $expr; dd(\@parse); print "\n"; } __END__ Y = A + (B*C) ["Y", "=", "A", "+", ["B", "*", "C"]] Y = A + (B' + (C*D)') ["Y", "=", "A", "+", ["B", "'", "+", ["C", "*", "D"], "'"]] Y = A*(B*(C'+D)') ["Y", "=", "A", "*", ["B", "*", ["C", "'", "+", "D"], "'"]]

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
