definition of \hss

[Bob]

Hello,

in the file ltplain.dtx, as compiled into latex.ltx, the
code makes a call to "\hss", but no such command is
defined. Where do I find the definition of "\hss"?

I need it to solve the following problem.

The latex environment "enumerate" defines the labels as follows:

\def\makelabel##1{\hss\llap{##1}}

The above code produces the default look of enumerations:

1. sdj fks jfksd f fff
sdjfk sjdfdfk lsdkf
2. s kdls kdfl;ds f; f
dfjks dfjksdf jkls.
...
100. df jskdf jks dlfl
jsdkf jskdfl jkfdf.

I want to change the above look into the following:

1. df jksd fkjsdl f
djf ksjdfk jsdkf jksd l
dklf dklf dk fld klfd l
2. sdfj ksdjf ksdjf
df jksdf jkls dfjksd fl
dk kld fkls;df kld fkld
...
100. s jkf jdff jkl
sdklf sk dlf ksld;f kl.

I tried the code below, but it fails.

\def\makelabel##1{\hspace*{\parindent}\hss\llap{##1}\hspace*{1em}}



Thank you.

\hss ("horizontal stretch or shrink", glue that is infinitely stretchable
and shrinkable) is a TeX-primitive. It is explained e.g. in the TeXbook or
in TeX by topic.

Taking a second look at your posting I thought that it would probabely be
best to change \itemindent and the like in enumerate or create your own
list directly from the list-environment.

This is the code I am playing with. The left margins are not
working as I expect. The nasty bit is the nesting of
environments.

of course. there are working examples of this sort of thing in the
companion.

the list environment sets \parindent to \listparindent.

don't understand why that's unknowable.

\newlength{\theindent}\setlength{\theindent}{\parindent}

or change the value of \listparindent. may (of course) provoke
problems elsewhere.
these counters already exist. \newcount doesn't check name clashes
(because it's a plain command) and \@definecounter doesn't (because
it's an internal command, usually used after exercising
\@ifdefinable).

redefining counters causes extra registers to be allocated. this may
not be a problem ... today ...

there are working examples of this sort of thing in the companion.

That's were I am coming from, moving towards an enumerated
environment whose items look like normal paragraphs [see above].

The task is not as straightforward as the trivial examples in the
Companion (I have the 1994 edition). The above code shows
the work I am doing. Feel free to join me.

To make the leftmargin problems stick out, try the followings:

\def\makelabel##1{.\hspace*{\theindent}.{##1}\hspace*{1ex}}%

and comment out the spec for the leftmargin.
