Question # 1 : generating the doc and sty files in the directory where they belong.

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

$ find $PWD -type d -name foo
/home/er/Documents/dev/LaTeX/texmf-dist/tex/latex/foo
/home/er/Documents/dev/LaTeX/texmf-dist/source/foo
/home/er/Documents/dev/LaTeX/texmf-dist/doc/latex/foo

I tried to put either of

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

\usedir{tex/latex/foo}
\usedir{./texmf-dist/tex/latex/foo} 
\usedir{home/er/the rest of the path/texmf-dist/tex/latex/foo}

just before\endpostamble, as in the code excerpted from conteq below, but it seems to be ignored (sty and pdf created in the same directory as that of dtx), so I must have misunderstood its purpose.

Here's an excerpt from conteq.dtx, from which foo.dtx is based:

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

\endpostamble
\usedir{tex/latex/conteq}
\generate{
  \file{\jobname.sty}{\from{\jobname.dtx}{package}
                      \from{\jobname.dtx}{layouts}}
}
%</install>
%<install>\endbatchfile
%<*internal>
\generate{
  \file{\jobname.ins}{\from{\jobname.dtx}{install}}
}
\nopreamble\nopostamble
\generate{
  \file{README.txt}{\from{\jobname.dtx}{readme}}
}

Question #2

In the section Example, the same code is repeated twice, once verbatim, the other not. Is there a way to avoid this duplication?

Another question about l3doc: how to do you get the index and the changes to appear in the generated pdf? I was hoping removing ^^A from this would do it. Not.

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

%\StopEventually{^^A
%  \PrintChanges
%  \PrintIndex
%}

A full example here (my repository) : https://github.com/er-cpp/erw-l3/blob/master/erw-l3.dtx

Another question about l3doc: how to do you get the index and the changes to appear in the generated pdf?

Answer is in the log file: to generate the change history, do

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

$ makeindex -s gglo.ist -o cooking-units.gls cooking-units.glo

and then run pdflatex once more.
