%% Package: spectralsequences v1.2.0 2017-09-16 2017-09-16
%% Author: Hood Chatham
%% Email: hood@mit.edu
%% Date: 2017-12-10
%% License: Latex Project Public License
%%
%% File: sseqmessages.code.tex
%% Exposes: Error message redirects?
%%
%% Set up fancy error messages
%%
%% The error handling system is build on top of l3msg. l3msg produces errors like:
%%
%% !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
%% !
%% ! LaTeX error: "<package>/<error-name>"
%% !
%% ! <error message text>
%% !
%% ! See the <package> documentation for further information. % produced by \msg_see_documentation_text:n{<package>}
%% !...............................................
%%
%% The user will see underneath it l.<line number> <text on line>
%%
%% Unfortunately, if the error is in a \foreach statement, the user will only see the final line of the foreach loop, often just the close brace.
%% It's impossible to tell from this where in the \foreach the error occurred. Similar problems occur if the command is inside a user command.
%%
%% We're going to modify this file to improve the situation.
%%
%% If the command is in a forloop or a user command I want to:
%% -- annotate the error with the command that caused it, or the previous command if the error occurred before I can know what the current command looks like.
%% -- present a stack trace to inform the user where exactly the problem occurred
%%
%%
%% We automatically print the annotation and stack trace at the end of all l3msg messages by hooking into \msg_see_documentation_text:n.
%% The annotation and stack trace are prepared by a command \sseq@error@setup which we hook into the beginning of the latex3 message processing code.
%%
%% Here's an example of the result:
%%
%% !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
%% !
%% ! spectralsequences error: "index-too-large"
%% !
%% ! Index '-3' provided for target of structure line is too large -- only 1
%% ! classes exist at position (32,8).
%% !
%% ! (Error occurred during call "\structline(16,-1,-1)(16,0,-3)", in the % This is the annotation
%% ! \foreach block that ends on line 158, with variable values: \n = 2.) % it's stored in \sseq@error@annotation
%% !
%% ! Stack trace: % This is the stack trace
%% ! \towergroupb (8*\n ,4*\n ) % Produced by \sseq@printstacktrace
%% ! \foreach \n in {2,3,4}
%% !
%% ! See the spectralsequences documentation for further information.
%% !
%% ! Type <return> to continue.
%% !...............................................

If you need to have this many classes in this position, you can make your own class pattern with \string\sseqnewclasspattern, but you might want to consider alternatives like using one class to represent multiple generators in some way -- it is hard to make a diagram look good with large numbers of classes in one position.%

You said '#1\ifx\pgfkeyscurrentvalue\pgfkeysnovalue@text\else=\pgfkeyscurrentvalue\fi', but
no coordinate transforms are allowed in the body of sseqpage or sseqdata other than shifts by unit-free integers
except as options for tikz primitives or for scopes that only contain tikz primitives. If you need a coordinate transformation,
