perfectcut.sty --- Nested delimiters that consistently grow regardless
of the contents.
This package defines the command \perfectcut#1#2 which displays a
bracket <#1||#2>. Various delimiters are similarly defined. The effect
of these commands is to let the delimiters grow according to the number
of nested \perfectcommands (regardless of the size of the contents).
The package is originally intended for solving a notational issue
regarding the representation of abstract-machine-like calculi in proof
theory and computer science. For general use, the package also defines
commands for defining custom delimiters that behave in the same way.
This package also offers a sound reimplementation of \big, \bigg, etc.
Release notes:
2.3 07/17: * When using scalerel, only use \ThisStyle for the outermost
command due to performance issues.
2.2 04/17: * By default, use the scalerel package instead of the mathstyle
package to compute the nested mathstyle.
* The option nomathstyle and the command \cutstyle are
deprecated.
* The option mathstyle is introduced, to use when scalerel is
too slow.
2.1 06/15: * the spacing inside cases can be contolled with \cutcasebarskip
* corrected a bug where vertical bars would shrink horizontally
* corrected the spacing of middle delimiters
2.0 11/14: * The package now offers general-purpose commands for
defining arbitrary nested delimiters that consistently
grow regardless of the contents (\perfectunary and
\perfectbinary)
* Added the behaviours CurrentHeight and
CurrentHeightPlusOne alongside the existing behaviour
IncreaseHeight.
* Added the stock commands \perfectcase, \perfectparens,
and \perfectbrackets intended for use in the context
of abstract-machine-like calculi.
1.9b 05/14: added the option fixxits to fix vertical alignment with the
XITS math font.
1.9 02/14: added \perfectcut,\perfectbra,\perfectket; fixed bug with graphicx
not being included; publication on CTAN.
1.8 01/14: added documentation (no new feature).
1.7 11/13: added \cutangleouterskip.
1.6 10/13: new commands \cutbraprimitive and \cutketprimitive.
1.5 09/13: possible to disable mathstyle (option nomathstyle, see
the warning below).
1.4 08/13: possible to choose between \vert\vert and \Vert (option realVert)
(\cutinterbarskip is used only with the former).
1.3 08/13: fixes the alignment of angles with the math axis.
1.2 06/13: first public release.
