How can I replicate a command name as an argument?

Question

I've searched for but not found an answer to this.

I am using two layers of \newcommands to create symbols inline with text, using \includegraphics. (It's for music symbols.)

At present, I have this as the generic command:

\newcommand*{\inlineImage}[2]{\raisebox{#1pt}{\fbox{\includegraphics{__#2__}}}}

And then many commands of the form:

\newcommand*{\Eighth}{\inlineImage{0}{Eighth}}
\newcommand*{\Sixteenth}{\inlineImage{-1.5}{Sixteenth}}

This works, but it is cumbersome to type the same text twice during set up. Of course, I could employ a command with arguments in my document body, but I don't want to do that. Is there a way to replace the specific commands with something of the form:

\newcommand*{\Sixteenth}{\inlineImage{-1.5}{<thecommandname>}}

Answer 1

The etoolbox package provides the \csdef command:

\newcommand*{\inlineImage}[2]{\raisebox{#1pt}{\fbox{\includegraphics{__#2__}}}}
\newcommand*\defnote[2]{\csdef{#1}{\inlineImage{#2}{#1}}}

Then use

\defnote{Eighth}{0}
\defnote{Sixteenth}{-1.5}

to create the macros \Eighth and \Sixteenth as you wanted.

Answer 2

To make command from text use \csname .. \endcsname macros. For example, if you will write

\def\newnote#1{\expandafter\def\csname #1\endcsname{\inlineImage{-1.5}{#1}}}

then commands like

\newnote{Fourth}
\newnote{Eighth}
\newnote{Sixteenth}

will define notes \Fourth, \Eighth and \Sixteenth, which will insert appropriate images.
