The following string displays in the command window formatted as a hyperlink. How do I display the entire contents of str without formatting?
>> str = '<test TEST>'
str =
TEST

This is a really great question and MATLAB needs a way to turn off string formatting. Sometimes we want to know what is in our strings and not have them look pretty.

You can replace all the occurrences of href by HREF for display:
str = {'<test TEST1>';'<test TEST2>'};
dispStr = regexprep(str,'href','HREF');
disp(dispStr)

What about corrupting the string with spaces and backspaces ...
str = '<test TEST>';
showstr = @(str)([sprintf('%c \b', str), sprintf('\n')]);
showstr(str)
This means that you can see all the content of your string without any formating (including formatting strings like \n) and don't have to guess what MATLAB is going to do.

Can anyone eliminate the use of eval?
In a comment to my other answer, Jonathan said "I would rather have BOTH: (1) a display function that does not format, and (2) a global setting to turn off all display formatting." This can be achieved for strings with a little bit of work.
1. Create a folder @char and add it to the MATLAB path
2. Inside @char add the following two functions (with appropriate names)
function disp(X)
if ischar(X) && ~isempty(getappdata(0, 'FormatString')) && ~getappdata(0, 'FormatString')
X = [sprintf('%c \b', X), sprintf('\n')];
end
builtin('disp', X);
end
function display(X)
if ischar(X) && ~isempty(getappdata(0, 'FormatString')) && ~getappdata(0, 'FormatString')
X = [sprintf('%c \b', X), sprintf('\n')];
end
eval([inputname(1), ' = X;']);
eval(['builtin(''display'', ', inputname(1), ');']);
end
You can then toggle the formating as follows:
>> setappdata(0, 'FormatString', []);
>> str = '<test TEST>'
TEST
>> setappdata(0, 'FormatString', true);
>> str = '<test TEST>'
TEST
>> setappdata(0, 'FormatString', false);
>> str = '<test TEST>'
<test TEST>

@Jonathan, 1) can you share your EVAL free solution, 2) please ask the hover question as a new question, 3) please consider voting for some of the answers that you like.

The only way I could think of is:
fprintf('< \b');fprintf('a href="test">TEST</a>')
Outputis:
<test TEST>
