I'm using the moderncv document type and trying to create a new command similar to the cventry. I'm trying to define in the preamble as below:

newcommand*{cvthing}[4][.25em]{%

    savebox{cvthingyearbox}{%

        hspace*{2separatorcolumnwidth}%

        hintstyle{#2}}%

    setlength{cvthingtitleboxwidth}{widthof{usebox{cvthingyearbox}}}%

    setlength{cvthingtitleboxwidth}{maincolumnwidth-cvthingtitleboxwidth}%

    begin{minipage}{maincolumnwidth}%

        parbox[t]{cvthingtitleboxwidth}{%

            strut%

            {bfseries#3}%

            {strut}%

        usebox{cvthingyearbox}%

    end{minipage}%

    ifx&#4&%

    else{%

        newline{}%

        begin{minipage}[t]{maincolumnwidth}%

            small%

            #4%

    end{minipage}}fi%

    paraddvspace{#1}}

but I get these errors:

File ended while scanning use of @xargdef.

You have requested package `moderncvheadi', but the package provides `moderncvheadi'.

You have requested package `moderncvbodyi', but the package provides `moderncvbodyi'.

I've been using LaTeX for a few years but haven't tried to change much. If one could please explain what I am doing wrong?

In your given code snippet are severalissues, some I can correct, some not because you did not told us what you want to archive ...

Please add more informations about your command in your question!

• To use a new box you need to initialize it: @initializebox{cvthingyearbox}
  


• To use a new length you have to define it: newlength{cvthingtitleboxwidth}
  


• Because we have to use @initializebox we need to use makeatletter and makeatother
  


• Some of your brackets are in the wrong position. For example: you can not open an parbox and close inside it an minipage, opened before the parbox ...

You can try the following compiling code snippet, but the result is still ugly, because I do not know, what you want:

makeatletter % <=======================================================

@initializebox{cvthingyearbox} % <====================================

newlength{cvthingtitleboxwidth} % <===================================
