Sorry if my question is elemental. I have start learning LaTeX a month ago. I'm learning at the same time as have new ideas. That being said, someone could help me to understand a simple example of clist in expl3? What's wrong with this code?

documentclass{article}

usepackage{xparse}



ExplSyntaxOn



NewDocumentCommand{DeclareListOfValues}{ m m }

{

    clist_new:N  g_list_of_values_#1

    clist_set:Nn g_list_of_values_#1 {#2}

}



NewDocumentCommand{GetValueFromList}{ m m }

{

    clist_item:Nn g_list_of_values_#1 {#2}

}



ExplSyntaxOff



DeclareListOfValues{FirstList}{1.11, 1.22}



begin{document}

    GetValueFromList{FirstList}{2} % -> 1.22

end{document}

I would appreciate any help.

  Use the c variants instead of N, i.e. clist_new:c {g_list_of_values_#1} etc.

You can't just tack #1 on to the end of a variable name. Instead you should use clist_new:c, which takes a "command name". Although not mandatory, the recommended style is to end your clist varaible names with clist.

Here is a corrected version of your code.

documentclass{article}

usepackage{xparse}



ExplSyntaxOn



NewDocumentCommand{DeclareListOfValues}{ m m }

{

    clist_new:c  {g_list_of_values_#1_clist}

    clist_set:cn {g_list_of_values_#1_clist} {#2}

}



NewDocumentCommand{GetValueFromList}{ m m }

{

    clist_item:cn {g_list_of_values_#1_clist} {#2}

}



ExplSyntaxOff



DeclareListOfValues{FirstList}{1.11, 1.22}



begin{document}

    GetValueFromList{FirstList}{2} % -> 1.22

end{document}
