Syntax

public static class ParseExtensions

Methods

GroupUntil<TSource>(IEnumerable<TSource>, Func<TSource, Boolean>, Boolean)

Gather elements of source into a group while predicate returns false. If predicate returns true, finish the current group and start a new one.

Declaration

public static IEnumerable<Grouped<TSource>> GroupUntil<TSource>(this IEnumerable<TSource> source, Func<TSource, bool> predicate, bool inclusive = false)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source
System.Func<TSource, System.Boolean>	predicate
System.Boolean	inclusive	If true, the element that caused predicate to return false will be put in the current group. Otherwise, it'll be in the next one.

Returns

Type	Description
System.Collections.Generic.IEnumerable<Grouped<TSource>>

Type Parameters

Name	Description
TSource

GroupWhile<TSource>(IEnumerable<TSource>, Func<TSource, Boolean, GroupWhileAction>)

Groups elements according to pickAction. For each element, pickAction is called with the element and whether the function is currently making a group. Groups will be yielded when complete- that is, when pickAction returns LeaveExclude or LeaveInclude.

Declaration

public static IEnumerable<Grouped<TSource>> GroupWhile<TSource>(this IEnumerable<TSource> source, Func<TSource, bool, GroupWhileAction> pickAction)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source
System.Func<TSource, System.Boolean, GroupWhileAction>	pickAction

Returns

Type	Description
System.Collections.Generic.IEnumerable<Grouped<TSource>>

Type Parameters

Name	Description
TSource

MergeLastIf<TSource>(IEnumerable<TSource>, Func<TSource, Boolean>, Func<TSource, TSource, TSource>)

Call predicate on each element. If that predicate returns true, then call merge on the current and previous elements and yield that instead of either the current or previous element.

Declaration

public static IEnumerable<TSource> MergeLastIf<TSource>(this IEnumerable<TSource> source, Func<TSource, bool> predicate, Func<TSource, TSource, TSource> merge)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source
System.Func<TSource, System.Boolean>	predicate	If this is true for current, call merge(current, previous)
System.Func<TSource, TSource, TSource>	merge	If predicate(current) is true, yield merge(current, previous) instead of current or previous.

Returns

Type	Description
System.Collections.Generic.IEnumerable<TSource>

Type Parameters

Name	Description
TSource

SkipBetween<TSource>(IEnumerable<TSource>, Func<TSource, Boolean>, Func<TSource, Boolean>)

Return elements from source until startPredicate returns true, then skip them until endPredicate returns true. Note that the element endPredicate returns true for will be returned.

Declaration

public static IEnumerable<TSource> SkipBetween<TSource>(this IEnumerable<TSource> source, Func<TSource, bool> startPredicate, Func<TSource, bool> endPredicate)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source
System.Func<TSource, System.Boolean>	startPredicate	When this returns true, begin skipping elements.
System.Func<TSource, System.Boolean>	endPredicate	When this returns true, stop skipping elements and yield the current one.

Returns

Type	Description
System.Collections.Generic.IEnumerable<TSource>

Type Parameters

Name	Description
TSource

Stringify(IEnumerable<Argument>)

Prettyprint an array of Arguments, with a comma and space between each one.

Declaration

public static string Stringify(this IEnumerable<Argument> source)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<Argument>	source

Returns

Type	Description
System.String

Stringify(IEnumerable<Char>)

Turn an IEnumerable of chars into a string.

Declaration

public static string Stringify(this IEnumerable<char> source)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<System.Char>	source

Returns

Type	Description
System.String
