How to create a string comparison with xparse's NewDocumentCommand?
0
My MWE was created with the help of these two Q&As: 1 and 2.
MWE:
documentclass{article}
usepackage{xparse}
usepackage{xstring}
usepackage{pdftexcmds}
% Command declaring a global definition if argument not empty, and using a pre-defined empty definition if argument empty
ExplSyntaxOn%
NewDocumentCommand{Client}{g}%
{%
IfNoValueTF{#1}%
{%
tl_use:N g_jalep_client_tl%
}%
{%
tl_gset:Nn g_jalep_client_tl {#1}%
}%
}%
tl_new:N g_jalep_client_tl%
ExplSyntaxOff%
% Attempt using pdfstrcmp

Client{Adam}
% Attempt using xstring
par My client should be Adam: IfSubStr{Adam}{Client}{Adam}{Eve}
% Attempt using pdfstrcmp

end{document}
Output:
Notes:
- The
IfSubStrandfooline work when there exists something like:newcommand{Client}{Adam}ornewcommand{Client}{Eve}ornewcommand{Client}{Anything}. - From this, I'm inclined to believe
Clientproduces something other than a string? How do I change this/convert this/work with this when I'm trying to create an if-else statement?
Question:
How do I make a string comparison with the NewDocumentCommand shown in my MWE? Something like: If Client = Adam, then print: Adam, else print: Eve

Are you open to alterations to the definition ofClient?

@Werner Yes, though in my document: 1.Clientis always called either empty like this:Client{}or with any argument like this:Client{Argument}. 2.Client{}orClient{Argument}should print nothing, and only the commandClientshould print whatever the global definition defined withClientis

So, a first call toClient{<name>}destroys its and just stores the<name>.
