Text Formatting ⇒ Code Redefinition for Vector Arrow

[ghostanime2001]

In the esvect package, I modified the vertical shift of the vector arrow in the "implementation" section of the package. I want to redefine the command \vv with the changed vertical shifts. I used \renewcommand but there is an error. Please take a look at my code. Thanks!

Code: Select all

\documentclass{article}
\usepackage[b]{esvect}  
\makeatletter
\def\vectfill@{\traitfill@\relbaredd\relbareda\fldr}
%\end{macrocode}
 %Construction of the arrow:
 % \begin{macrocode}
 \def\traitfill@#1#2#3#4{%
 $\m@th\mkern2mu\relax#4#1\mkern0mu%on met \relbaredd au d\’ebut
 \cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%remplit avec relbareda
 \mkern0mu#3$%
 }

% the above code has changed values of 0.2mu

\makeatletter
    \def\overvect@#1#2#3{\vbox{\ialign{##\crcr%
     \noalign{\kern-0.5pt\nointerlineskip}#1#2\crcr%
     \noalign{\kern0.5pt\nointerlineskip}$\m@th\hfil#2#3\hfil$\crcr}}}

% the above code has changed values of +-0.5pt
\begin{document}
$\vv{i}\vv{a}$
\end{document}

I'm not sure what you want us to do here. As far as I can see this is the code from the package but with changed length values. You can leave the first definition as it is exactly the same as in the package and you should undo the catcode change from \makeatletter after the redefinitions with \makeatother:

Code: Select all

\documentclass{article}
\usepackage[b]{esvect}
\makeatletter
\def\traitfill@#1#2#3#4{%
  $\m@th\mkern2mu\relax#4#1\mkern0mu%on met \relbaredd au d\’ebut
  \cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%remplit avec relbareda
  \mkern0mu#3$%
}

% the above code has changed values of -1.5mu => 0mu

\def\overvect@#1#2#3{\vbox{\ialign{##\crcr%
  \noalign{\kern-0.5pt\nointerlineskip}#1#2\crcr%
  \noalign{\kern0.5pt\nointerlineskip}$\m@th\hfil#2#3\hfil$\crcr}}}

% the above code has changed values of -.7pt => -.5pt and -.3pt => .5pt
\makeatother
\begin{document}

$\vv{i}\vv{a}$

\end{document}
