enumitem: \ref a custom item

[Alexander Zimmermann]

Hi all,

at one point I want to switch from numbers to custom label in my
enumeration. No problem so far. However, when want to reference the
custom label later on (\ref or \autoref), I get "item (1)" and not
the desired "item (R)". How could I fix it?

It's a defiency in LaTeX: \label refers to \refstepcounter, but the
optional argument of \item suppresses the call of \refstepcounter.

Workaround:

\rlap{%
\raisebox{.7\baselineskip}[0pt]{%

Yes, but if I edit the pdf, each label is already assigned a name /Names
[ R (Item.1) ... R (Item.2) ... R (Item.3) ... ]

in a sequence. Is this possible just to change the destination name ?
Or duplicate it with another user-friendly name ?

If I had time to look at hyperref log, I'm sure I would find a way to do
that...

Yours sincerely.

No, they are created by \refstepcounter.

I don't see, how this is related to \ref.

[Alexander Zimmermann]

I really don't understand what you do, nevertheless it works :-)

Thanks.

Hi Heiko,

thank you very much! It works.

Last but not least, I tried to extend \autoref, so that it will produce
"Step (1)" or "Step (R)". A global
"\newcommand*{\Itemautorefname}{Step}" is not the cleverest solution...

I tried to expand your code. It compiles, however I get a warning

"destination with the same identifier (name{Step.0}) has been already
used, duplicate ignored"

and nevertheless, I have the feeling that the hypertargets are not correct.

Thank you so much,

Alex

Also the \rlap/\raisebox stuff should be used to place the target more

I can propose you another solution, closer to "enumitem" (leaving
hyperref gentle then ;-)

The idea is that the item is made using :
\makelabel#1 => \rlap{ \font #1 }\hss

Therefore, it is possible to capture the "argument of \font" (with a
slight modification of \makelabel) :
\makelabel#1 => \rlap{ \font #1\@@} \hss

Then \font will capture the item delimited by \@@ and set the right
label.


Just a problem occurs when label is automatic, but I bypass the problem
as explained after the ECM :

%--------------------------------------------------
\documentclass{article}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{etoolbox}
\usepackage{enumitem,blindtext}
\usepackage[verbose]{hyperref}

\begin{document}\makeatletter

\renewcommand\***@alignleft{% This is where \makelabel is defined
\def\makelabel##1{\rlap {\***@format ##1\@@}\hss}}


\newrobustcmd\LabelizeItem[1][]{\***@m{#1}}

\def\***@m#1#2\@@{%
\ifx\@itemlabel#2\relax
\***@edef\@currentlabel{#2}%
\***@edef\@currentlabel{%
\expandafter\@firstofone\@currentlabel}% here is the "trick"
\else
\def\@currentlabel{#2}% user defined item : no problem
\fi
%\message{@currentlabelis : \@currentlabel}% debug purpose
\label{#1:\@currentlabel}%
#2% "reinserts" the item
}

\begin{enumerate}[label=(\arabic*),ref=(\arabic*),align=left,
font={\bfseries\LabelizeItem[step]}]% font calls \LabelizeItem
\item
This is step one
\item[{(R)}]
\blindtext
\item
\autoref{step:(1)} \quad \autoref{step:(R)}
\end{enumerate}

\end{document}\endinput
% ------------------------------------------

If you give the item :
\item[{(R)}]
Then argument of \makelabel's {(R)}

If the item is automatic, it is :
\@itemlabel
which expands (after a chain containing \@arabic here) to : {{(1)}}

Therefore, I had to get out of one level of braket, if order not to have
a final label looking like : "step:{(1)}" which is obviouly tedious.


Well, is this good enough ?
(if align = right, some changes have to be made, but it is seldom the
case...)

[GL]

In the same idea of my post of 20:20, I have a clearner solution, just
using the "before=<code>" key from enumitem, and leaving align=left or
right quiet...

Therefore, you juste have to add :
before = \AutoLabelPrefix{step:}
to your keys in order to get the correct (finger crossed) behaviour.

En français dans le texte !

J'ai continué pour implémenter un schéma générale de référence des
listes, grâce à zref.

Ca devrait être terminé bientôt (question d'interface...)

Hi,

I like your code. However, it is possible to change the code so that I
get "Step r" and not "item (R)" when I use \autoref{step:(R)}.

Or even better: use the parameter of your \AutoLabelPrefix{} to produce
the label in the \newlabel{...}, so that I can use
\newcommand{\Blaautorefname}{Bla} to produce "Bla (R)"

Yes you can, but I don't think it is the purpose of \autoref !

Say :
\hyperref[step:(R)]{whatever you wish to be displayed}

I'm on the way with zref and various ways to reference items.
I have still problems to deal properly with(out) duplicate labels.

No??? IMO this is exactly the use case for autoref! I don't want to
type every time:

\hyperref[step:(R)]{Step~\begin{NoHyper}\ref{step:(R)}\end{NoHyper}}

You think that this a comfortable method? I have several algorithms in
my document (for which I use the enumeration) with a dozen of references
