Methods

dchar peek(const size_t index) @safe pureGet character at specified index relative to current position.

dchar peek() @safe pureOptimized version of peek() for the case where peek index is 0.

char peekByte(const size_t index) @safe pure nothrow @nogcGet byte at specified index relative to current position.

char peekByte() @safe pure nothrow @nogcOptimized version of peekByte() for the case where peek byte index is 0.

char[] prefix(const size_t length) @safe pureGet specified number of characters starting at current position.

char[] prefixBytes(const size_t length) @safe pure nothrow @nogcGet specified number of bytes, not code points, starting at current position.

char[] slice(const size_t end) @safe pureGet a slice view of the internal buffer, starting at the current position.

dchar get() @safe pureGet the next character, moving buffer position beyond it.

char[] get(const size_t length) @safe pureGet specified number of characters, moving buffer position beyond them.

void forward(size_t length) @safe pureMove current position forward.

void forward() @safe pureMove current position forward by one character.

Mark mark() const pure nothrow @nogc @safeGet filename, line and column of current position.

Mark mark(size_t advance) const pure @safeGet filename, line and column of current position + some number of chars

inout(string) name() ref inout @safe return pure nothrow @nogcGet file name.

uint line() const @safe pure nothrow @nogcGet current line number.

uint column() const @safe pure nothrow @nogcGet current column number.

size_t charIndex() const @safe pure nothrow @nogcGet index of the current character in the buffer.

Encoding encoding() const @safe pure nothrow @nogcGet encoding of the input buffer.

void checkASCII() @safe pure nothrow @nogc

dchar decodeNext() @safe pure

Constructors

this(ubyte[] buffer, string name = "<unknown>")Construct a Reader.

fnauto toUTF8(ubyte[] input, const UTFEncoding encoding) @safe pure nothrow

fnbool isPrintableValidUTF8(const char[] chars) @safe pureDetermine if all characters (code points, not bytes) in a string are printable.

fnsize_t countASCII(const(char)[] buffer) @safe pure nothrow @nogcCounts the number of ASCII characters in buffer until the first UTF-8 sequence.
