number of bits, modulo 2^64 (lsb first)

array<int> state 

state (ABCD)

xURL

a better URL structure that contains all elements

string hash 

the part after the #, without the leading #

possible password that was in the url

int port 

the port number specified in the URL

string protocol 

protocol used, like http://, https://, ftp://. But without the '://' part. (ignore the space between the two slashes, it's required because of a bug in UE2)

Functions

int AdvSplit(string input, string delim, out array<string> elm, optional string quoteChar )

Split a string with quotes, quotes may appear anywhere in the string, escape the quote char with a \ to use a literal.
Qoutes are removed from the result, and escaped quotes are used as normal quotes.

array<string> Base64Decode(array<string> indata )

Decode a base64 encoded string

array<string> Base64Encode(array<string> indata, out array<string> B64Lookup )

base64 encode an input array

Base64EncodeLookupTable(out array<string> LookupTable )

Generate the base 64 encode lookup table

string basename(string filename )

get the base filename

int daysInYear(int year )

returns the number of days in a year

string DecToHex(int dec, int size )

convert a decimal to hexadecimal notation

string dirname(string filename )

get the dirname of a filename, with traling slash

int getPortByProtocol(string protocol )

return the default port based on the protocol

int HexToDec(string hexcode )

convert a hexadecimal number to the integer counterpart

string HTTPResponseCode(int code )

return the description of a HTTP response code

bool isLeapYear(int year )

returns if year is a leap year

int leapsThruEndOf(int y )

Logf(name Comp, coerce string message, optional int level, optional coerce string Param1, optional coerce string Param2 )

Write a log entry

MD5Decode(out array<int> output, array<byte> input, int len )

MD5Encode(out array<byte> output, array<int> input, int len )

MD5Final(out array<byte> digest, out MD5_CTX context )

finalize the MD5 context

MD5Init(out MD5_CTX context )

initialize the MD5 context

MD5Move(string src, int srcindex, out array<byte> buffer, int bufindex, int len )

string MD5String(string str )

return the MD5 of the input string

string MD5StringArray(array<string> stra, optional string Concat )

Return the MD5 of the input string array. Concat is added after each line.

MD5Transform(out array<int> Buf, array<byte> block )

MD5Update(out MD5_CTX Context, string Data, int inputLen )

update MD5 context

bool parseUrl(string inURL, out xURL outURL )

parses the inURL to an xURL structure, return true when succesful

string RawUrlDecode(string instring, optional bool bIgnorePlus )

This will decode URL encoded elements. If bIgnorePlus is set to true '+' will not be changed to a space

string RawUrlEncode(string instring )

Encode special characters, you should not use this function, it's slow and not secure, so try to avoid it.
This is replace the following characters: ";", "/", "?", ":", "@", "&", "=", "+", ",", "$" and " "

ReplaceChar(out string instring, string from, string to )

replace part of a string

int ROTATE_LEFT(int x, int n )

int stringToTimestamp(string datestring, optional int TZoffset )

Parse a string to a timestamp

The date string is formatted as: Wdy, DD-Mon-YYYY HH:MM:SS GMT
TZoffset is the local offset to GMT

int timestamp(int year, int mon, int day, int hour, int min, int sec )

Create a UNIX timestamp.
Warning: Assumes info is passed in GMT. So make sure you correct the timezone if you are going to send a timestamp generated with this function to an other server.

DateTime timestampToDatetime(int timestamp )

converts a timestamp to a DateTime record

string timestampToString(int timestamp, optional string Timezone, optional string format )

convert a timestamp into a string.
Format can be one of the following strings:
"822", "1123" : RFC 822, updated by RFC 1123 (default), timezone is the TZ CODE
"850", "1036" : RFC 850, obsoleted by RFC 1036, timezone is the TZ CODE
"2822" : RFC 2822, timezone is a +0000 like string
"asctime": ANSI C's asctime() format, timezone is an integer that will increment the hour

Trim leading and trailing spaces

float TZtoOffset(string TZ )

string xURLtoString(xURL inURL, optional bool bIncludePassword )

converts a xURL to a string. bIncludePassword defaults to false
