@ref
@ref
is nearly the same as @xref
except that it does
not generate a `See' in the printed output, just the reference itself.
This makes it useful as the last part of a sentence.
For example,
For more information, @pxref{This}, and @ref{That}.
produces in Info:
For more information, *note This::, and *note That::.
and in printed output:
For more information, see Section 1.1 [This], page 1, and Section 1.2 [That], page 2.
The @ref
command sometimes tempts writers to express
themselves in a manner that is suitable for a printed manual but looks
awkward in the Info format. Bear in mind that your audience will be
using both the printed and the Info format. For example:
Sea surges are described in @ref{Hurricanes}.
looks ok in the printed output:
Sea surges are described in Section 6.7 [Hurricanes], page 72.
but is awkward to read in Info, “note” being a verb:
Sea surges are described in *note Hurricanes::.
You should write a period or comma immediately after an @ref
command with two or more arguments. If there is no such following
punctuation, makeinfo will generate a (grammatically
incorrect) period in the Info output; otherwise, the cross-reference
would fail completely, due to the current syntax of Info format.
In general, it is best to use @ref
only when you need some
word other than “see” to precede the reference. When “see” (or
“See”) is ok, @xref
and @pxref
are preferable.
