Methods

CodepointAt(string, int)

UTF-32 codepoint at the given char index, or 0 if past end.

public static int CodepointAt(string s, int index)

Parameters

s string

index int

Returns

int

CodepointDisplayWidth(int)

Terminal cell width of a single codepoint (1 or 2). Control chars return 0.

public static int CodepointDisplayWidth(int cp)

Parameters

cp int

Returns

int

CodepointSize(string, int)

Number of UTF-16 code units that make up the codepoint starting at index.

public static int CodepointSize(string s, int index)

Parameters

s string

index int

Returns

int

DisplayWidth(string, int, int)

Total display width of the substring [start, end).

public static int DisplayWidth(string s, int start, int end)

Parameters

s string

start int

end int

Returns

int

IndexAtColumn(string, int)

Char index whose column ≥ targetColumn (clamped to s.Length).

public static int IndexAtColumn(string s, int targetColumn)

Parameters

s string

targetColumn int

Returns

int

IsWordCodepoint(int)

Determines if a codepoint is part of a word (for word-jump).

public static bool IsWordCodepoint(int cp)

Parameters

cp int

Returns

bool

NextBoundary(string, int)

Char index of the next codepoint boundary at-or-after index.

public static int NextBoundary(string s, int index)

Parameters

s string

index int

Returns

int

PrevBoundary(string, int)

Char index of the previous codepoint boundary before index.

public static int PrevBoundary(string s, int index)

Parameters

s string

index int

Returns

int
