public enum ShellDialectFeatures

Fields

Name	Value	Description
`None`	`0`
`ExtendedTest`	`1`	The `[[ ... ]]` extended test construct.
`ArithmeticCommand`	`2`	The `(( ... ))` arithmetic command. POSIX defines no such command, so `sh` lacks it.
`HereString`	`4`	The `<<<` here-string redirection operator.
`DollarQuoting`	`8`	ANSI-C quoting (`$'...'`) and locale-translated strings (`$"..."`).
`Arrays`	`16`	Indexed and associative array assignments such as `a=(1 2 3)`.
`FunctionKeyword`	`32`	The `function` keyword form of a function definition.
`ProcessSubstitution`	`64`	Process substitution: `<(...)` and `>(...)`.
`Coproc`	`128`	The `coproc` keyword.
`SelectLoop`	`256`	The `select` loop.
`ZshExtensions`	`512`	The zsh `foreach ... end` loop and anonymous functions.
`PipelineChainOperators`	`1024`	The `&&` and `\|\|` pipeline chain operators (PowerShell 7 and later).
`TernaryOperator`	`2048`	The ternary `? :` operator (PowerShell 7 and later).
`NullCoalescing`	`4096`	The `??` and `??=` null-coalescing operators (PowerShell 7 and later).
`CleanBlock`	`8192`	The `clean` block in an advanced function (PowerShell 7.3 and later).
`DelayedExpansion`	`16384`	Delayed variable expansion using `!VAR!`.
`ArithmeticExpansion`	`32768`	The `$(( ... ))` arithmetic expansion. POSIX defines it, so every dialect in the family has it.
`ArithmeticExponentiation`	`65536`	The `**` exponentiation operator in arithmetic. POSIX defines no such operator, so `sh` lacks it.
