; NSIS LOGIC LIBRARY - LogicLib.nsh

;
; Description:
; Provides the use of various logic statements within NSIS.
;
; Usage:
; The following "statements" are available:
; If|IfNot|Unless..{ElseIf|ElseIfNot|ElseUnless}..[Else]..EndIf|EndUnless
; - Conditionally executes a block of statements, depending on the value
; of an expression. IfNot and Unless are equivalent and
; interchangeable, as are ElseIfNot and ElseUnless.
; AndIf|AndIfNot|AndUnless|OrIf|OrIfNot|OrUnless
; - Adds any number of extra conditions to If, IfNot, Unless, ElseIf,
; ElseIfNot and ElseUnless statements.
; IfThen|IfNotThen..|..|
; - Conditionally executes an inline statement, depending on the value
; of an expression.
; IfCmd..||..|
; - Conditionally executes an inline statement, depending on a true
; value of the provided NSIS function.
; Select..{Case[2|3|4|5]}..[CaseElse|Default]..EndSelect
; - Executes one of several blocks of statements, depending on the value
; of an expression.
; Switch..{Case|CaseElse|Default}..EndSwitch
; - Jumps to one of several labels, depending on the value of an
; expression.
; Do[While|Until]..{ExitDo|Continue|Break}..Loop[While|Until]
; - Repeats a block of statements until stopped, or depending on the
; value of an expression.
; While..{ExitWhile|Continue|Break}..EndWhile
; - An alias for DoWhile..Loop (for backwards-compatibility)
; For[Each]..{ExitFor|Continue|Break}..Next
; - Repeats a block of statements varying the value of a variable.
;
; The following "expressions" are available:
; Standard (built-in) string tests (which are case-insensitive):
; a == b; a != b
; Additional case-insensitive string tests (using System.dll):
; a S< b; a S>= b; a S> b; a S<= b
; Case-sensitive string tests:
; a S== b; a S!= b
; Standard (built-in) signed integer tests:
; a = b; a <> b; a < b; a >= b; a > b; a <= b; a & b
; Standard (built-in) unsigned integer tests:
; a U< b; a U>= b; a U> b; a U<= b
; 64-bit integer tests (using System.dll):
; a L= b; a L<> b; a L< b; a L>= b; a L> b; a L<= b
; ptrdiff_t integer tests
; a P= b; a P<> b; a P< b; a P>= b; a P> b; a P<= b
; size_t integer tests
; a Z= b; a Z<> b; a Z< b; a Z>= b; a Z> b; a Z<= b
; Built-in NSIS flag tests:
; ${Abort}; ${Errors}; ${RebootFlag}; ${Silent}; ${RtlLanguage};
; ${ShellVarContextAll}
; Built-in NSIS other tests:
; ${FileExists} a
; Any conditional NSIS instruction test:
; ${Cmd} a
; Section flag tests:
; ${SectionIsSelected} a; ${SectionIsSectionGroup} a;
; ${SectionIsSectionGroupEnd} a; ${SectionIsBold} a;
; ${SectionIsReadOnly} a; ${SectionIsExpanded} a;
; ${SectionIsPartiallySelected} a
; Additional tests:
; HK RegKeyIsEmpty SubKey
;
; Examples:
; See LogicLib.nsi in the Examples folder for lots of example usage.
