            README for the `ifnextok' package
       variant of \@ifnextchar not skipping spaces
                (C) Uwe Lueck 2011/06/02

`ifnextok' deals with the behavior of LaTeX's internal 
`\@ifnextchar' to skip blank spaces. This sometimes has surprising 
or for some users really unwanted effects, especially with 
brackets following `\\' when the user does not intend to specify 
an optional argument, rather wants that brackets are printed.
The package offers commands and options for modifying this 
behavior, maybe limited to certain parts of the document source.

A general method the package offers is 


so in "standard" circumstances `\\ [' prints a bracket in a 
new line. `\MakeNotSkipping<target>{<on-space>} modifies <target> 
so it executes <on-space> when followed by a space token.

KEYWORDS: macro programming, optional command arguments, 
          manual line breaks, humanities

ifnextok – Utility macro: peek ahead without ignoring spaces

The package deals with the behaviour of the internal command \@ifnextchar, which skips blank spaces. This has the potential to surprise users, since it can produce really unwanted effects. A common example occurs with brackets starting a line following \\: the command looks for an optional argument, whereas the user wants the brackets to be printed.

The package offers commands and options for modifying this behaviour, maybe limited to certain parts of the document source.
