How to renew quotation environment for custom margins and noindent for first line
Pander
How to renew quotation environment for custom margins. I would like to
set custom value for left and an identical for the right margin, e.g.
\mymargin. Also, I would like that quotation environment starts with a
\noindent for only the first line. As far as I am concerned it inject
a \noindent directly before the contents of the environment.
I know that it should look something like:
\makeatletter
\renewenvironment{quotation}
{\list{}{...}
{\endlist}
\makeatother
Please, how do I do this?
Thanks,
Pander

why don't you do what the rest of us do, look in the source
in article quotations is defined as
\newenvironment{quotation}
{\list{}{\listparindent 1.5em%
\itemindent \listparindent
\rightmargin \leftmargin
\parsep \z@ \@plus\p@}%
\item\relax}
{\endlist}
compare it with quote:
\newenvironment{quote}
{\list{}{\rightmargin\leftmargin}%
\item\relax}
{\endlist}
experimenting with these may bring you to the right solution (in the
mean time you will learn something)
play with \listparindent or \itemindent

\renewenvironment{quotation}
{\list{}{\leftmargin=<??>% <-- set here your margin
\listparindent \parindent
\itemindent \listparindent
\rightmargin \leftmargin
\parsep \parskip}%
\item\relax\noindent\ignorespaces}
{\endlist}

Have you forgot \setlength ? ;-)
\renewenvironment{quotation}[1][\leftmargin=1.5em]
{\list{}{\listparindent 1.5em
\itemindent \listparindent
\rightmargin \leftmargin
\parsep \z@ \@plus\p@ #1}%
\item\relax}
{\endlist}
\begin{quotation}
\begin{quotation}[\itemindent=2cm \leftmargin =2em]
more flexible...

GL, what are you talking about now?

I'd expected from you: \setlength {\itemident}{\listparindent}
with the braces and all that stuff ;-)

Do you even know what I posted?
copy'n'pasted from article.cls
why should I change it?
I get it, you do not like \setlength, so what? I find it handy in
several cases.
For example adding calc, \setlength allows additions, your syntax below
does not. A user cannot easily get \leftmargin = 1.5em + \parindent
(say). So for non-programmers \setlength has its advantages, not just
for programming macros, but also for user interfaces.

I would say only for user interface. And by the way since eTeX exists,
\def\setlength #1#2{#1\dimexpr #2\relax \relax }
provides all, with the same syntax as \dimexpr that is, an economy in
the learning of its usage.
tabu does not know \setlength: tracking an assignment in the log
{changing \dimen118=12pt into \dimen118=18pt}
is painful, tracking it amongst the lines produces by calc.sty is
impossible...

My goal is to use \parindent on the left and right of quotation and
when an indentation occurs inside a quotation env, it will be absolute
two times \parindent and relative on one \parindent.
When I do:
\rewenvironment{quotation}
{\list{}{\listparindent \parindent%
\itemindent \listparindent
\rightmargin \leftmargin
\parsep \z@ \@plus\p@}%
\item\relax}
{\endlist}
Nothing is changed in horizontal margins or indentation but an empty
line is added before and after the quotation. :S
