+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%% list handling
+%%
+%% Contribution by Jonathan P. Spratte (blame him!)
+%%
+%% The list implementation here has a few limitations. Those are:
+%%  1. not long, so no \par in the lists (but many used functions in pgfutil
+%%     aren't long as well)
+%%  2. list elements can't contain a Q with category code 3 (but the used
+%%     function \pgfutil@trimspaces doesn't support them as well, and this
+%%     should be a very rare token anyway)
+%%  3. list elements can't contain the token \pgf@circ@set@list as that is used
+%%     as the end marker
+%%  4. currently these lists are meant for numeric data (hence only
+%%     \pgf@circ@if@num@in@list is provided as a test), as a result there is
+%%     another limitation for the data here. If the list element contains no
+%%     hyphen '-', the element will be stored without further processing
+%%     'as-is' (well, after trimming spaces). If there is a hyphen we assume
+%%     well-behaved input data and will interpret this as a num-range without
+%%     further tests.
+%%
+%% Functions provided here are:
+%%  \pgf@circ@set@list<macro>{<csv-list>}
+%%    Parses the <csv-list> and stores the result inside <macro> (local
+%%    assignment). If a num-range given as <start - stop> (with or without
+%%    spaces) is found it will be expanded to <start>,<start+1>,...,<stop>.
+%%  \pgf@circ@if@num@in@list<macro>{<value>}{<true>}{<false>}
+%%    Checks whether <value> (numeric value, evaluated once with \numexpr) is
+%%    found inside the list stored in <macro>. There are two special cases: If
+%%    <macro> is undefined <false> is executed. If the list contains only one
+%%    element and that is `all' <true> is executed.
+
+% set the catcode of our marker
+\chardef\pgf@circ@temp=\the\catcode`\Q
+\catcode`\Q=3
+
+% lists will have the structure
+% <marker><element 1><marker>...<element n><marker>
+% As marker we use a Q with category 3. Under the assumption that no list
+% element does ever contain that token we can set the elements without braces,
+% allowing us to use \pgfutil@in@ to search for elements (see above). The other
+% token that isn't allowed to show up in the list is \pgf@circ@set@list, that we
+% use as another marker during parsing.
+% The other big restriction in this implementation is that lists can't contain a
+% \par (but \pgfutil@in@ doesn't support that anyway so there is not much
+% sense in supporting it here)

+% baselen is relative to pgfcirc@Rlen as ever; scaled if the class says so.
+% the value of 0.4 is the standard pin distance for a port with height=num pins
+% and matches the chip distance
+\ctikzset{ieeestd ports/baselen/.initial=0.4}
+% these are in term of baselen; width depends on height (fixed proportions)
+\ctikzset{ieeestd ports/height/.initial=2}
+\ctikzset{ieeestd ports/pin length/.initial=0.7}
+% the standard "not" circle should be 1/6.5 of height (diameter);
+% so radius/baselen=1/3.25/2    --- using 0.1 and no scaling is as a pole
+\ctikzset{ieeestd ports/not radius/.initial=0.154}
+\ctikzset{ieeestd ports/not radius fill/.initial=1}% change ony if you know why
+% the suggested xnor distance is is 1.24, so 1.25/3.25/2
+% xor/xnor leads go full in in IEEE; let this be optional
+\ctikzset{ieeestd ports/xor bar distance/.initial=0.192}%
+\ctikzset{ieeestd ports/xor leads in/.initial=1}%
+%
+% base size of a small external schmitt symbol
+%

+%
+% input management
+% we are using the same /tikz/number inputs than the legacy ports
+%
+\tikzset{/tikz/inner inputs/.initial=0} % using 0 means that all inputs are inner
+%
