@allowcodebreaks: Control Line Breaks in
Ordinarily, TeX considers breaking lines at ‘-’ and ‘_’
@code and related commands
(see @code), more or less as if they were “empty”
This is necessary since many manuals, especially for Lisp-family
languages, must document very long identifiers. On the other hand,
some manuals don’t have this problems, and you may not wish to allow a
line break at the underscore in, for example,
SIZE_MAX, or even
worse, after any of the four underscores in
So Texinfo provides this command:
to prevent from breaking at ‘-’ or ‘_’ within
@code. You can go back to allowing such breaks with
@allowcodebreaks true. Write these commands on lines by
These commands can be given anywhere in the document. For example, you may have just one problematic paragraph where you need to turn off the breaks, but want them in general, or vice versa.
This command has no effect except in HTML and TeX output.
