Functions

UTF8ToRaw
ascii UTF8ToRaw(char[] r)

Undo rawToUTF8.

arrayFromHex
ubyte[] arrayFromHex(char[] hex, ubyte[] buf)

Convenience helper

eatLine
T[] eatLine(T[] s, bool eatIncompleteLines)

T[] fastReplace(T[] what, T[] from, T[] to)
Undocumented in source. Be warned that the author may not have intended to support it.
fastSplit
T[][] fastSplit(T[] s, U d)
Undocumented in source. Be warned that the author may not have intended to support it.
findBestMatch
sizediff_t findBestMatch(string[] items, string target, float threshold)

Select best match from a list of items. Returns -1 if none are above the threshold.

fromZArray
C[] fromZArray(C[n] arr)
C[] fromZArray(C[] arr)

Return the slice up to the first NUL character, or of the whole array if none is found.

hexDump
string hexDump(const(void)[] b)

Formats binary data as a hex dump (three-column layout consisting of hex offset, byte values in hex, and printable low-ASCII characters).

string randomString(int length, string chars)
Undocumented in source. Be warned that the author may not have intended to support it.
rawToUTF8
string rawToUTF8(char[] s)

Convert any data to a valid UTF-8 bytestream, so D's string functions can properly work on it.

segmentByWhitespace
T[][] segmentByWhitespace(T[] s)

Covering slice-list of s with interleaved whitespace.

selectBestFrom
string selectBestFrom(string[] items, string target, float threshold)

Select best match from a list of items. Returns null if none are above the threshold.
