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.

perfectcut – Nested delimiters that consistently grow regardless of the contents
This package defines the command \perfectcut#1#2 which displays a bracket <#1||#2>. Various other delimiters are similarly defined (parentheses, square brackets ...). 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 was originally intended for solving a notational issue for direct-style continuation calculi in proof theory. For general use, the package also defines commands for defining other sorts of delimiters which will behave in the same way (see example in the documentation). The package also offers a robust reimplementation of \big, \bigg, etc.
