15.5 @w
{text}: Prevent Line Breaks
@w{text}
outputs text, while prohibiting line
breaks within text.
Thus, you can use @w
to produce a non-breakable space, fixed at
the width of a normal interword space:
@w{ } @w{ } @w{ } indentation.
produces:
indentation.
The space from @w{ }
, as well as being non-breakable,
also will not stretch or shrink. Sometimes that is what you want, for
instance if you’re doing manual indenting. However, usually you want
a normal interword space that does stretch and shrink (in the printed
output); for that, see the @tie
command in the next section.
You can also use the @w
command to prevent TeX from
automatically hyphenating a long name or phrase that happens to fall
near the end of a line. makeinfo
does not ever hyphenate
words.
You can also use @w
to avoid unwanted keyword expansion in
source control systems. For example, to literally write $Id$
in your document, use @w{$}Id$
. This trick isn’t effective
in Info or plain text output, though.
