Decodes percent-encoded codes in a URI path and converts "+" signs in the query component to spaces and returns the decoded string in UTF-8 encoding.
| uri | a URI request string to decode |
The URI string is divided into three parts:
"?" or "#" character"?" character terminating the path and up to a possible "#" character"#" characterFor all parts, any percent-encoded codes (RFC 3986 2.1) are decoded to the corresponinding character. The path component is identified and distinguished by a "?" or a "#" character. The path component is subjected to standard percent encoding. The query component is any part of the URI string following a "?" character up to the end of the URI string or until a "#" characer is found. The query component is subjected to special decoding for AJAX compatibility; "+" characters are decoded to ASCII space (therefore any "+" charaters in the query component of the URI must be encoded with percent encoding, such is the case with Qore::encode_uri_request() for example). The fragment component is identified as any text following a "#" character, and this is decoded with the same rules as in the path component.

| url | a URL string with percent-encodings to decode |
Encodes URI requests by substituting special characters in the path with percent-encoded equivalents and substituting spaces with "+" and "+" with the percent-encoded equivalent in the URI query component.
| url | a URL string to encode |
The URI string is divided into three parts:
"?" or "#" character"?" character terminating the path and up to a possible "#" character"#" characterFor all parts, any non-ASCII characters and the "%" character are subjected to percent encoding (RFC 3986 2.1). The path component is identified and distinguished by a "?" or a "#" character. Any spaces in the path component are also subjected to percent encoding. The query component is any part of the URI string following a "?" character up to the end of the URI string or until a "#" characer is found. Spaces in the query component are encoded with "+" for compatibility with AJAX libraries, and "+" signs are subjected to percent encoding. The fragment component is identified as any text following a "#" character, and this is encoded with the same rules as in the path component.
"+" in the query component of the URI stringEncodes URLs by substituting '%' characters with '%25', spaces (' ') with '%20', and non-ascii characters by percent-encoded representations.

Returns a list based on the argument list but optionally with elements removed and/or added from a certain index.
Exceptions can only be thrown here if objects are removed from the list and this causes them to go out of scope and an exception is thrown in one of the destructors
| l | the list to process |
| start | the starting element (where the first element is 0) to start removing (and/or adding) elements; if this value is negative, it gives the offset from the end of the list |
| len | the number of list elements to remove; if this argument is 0 then no elements are removed; if this value is negative, then it gives an offset from the end of the list (ie -2 means remove all elements up to but not including the two last elements) |
| nlist | the new list for inserting new elements |
This function always returns an empty string "".
This function variant is included for backwards-compatibility
| str | no action is taken on the argument |
"" Returns a string based on the argument string but with characters removed from a certain character index.
An exception can only be thrown here if an invalid multi-byte encoding is found
| str | the string to process |
| start | the character index (where the first character is 0) to start removing characters; if this value is negative, it gives the offset from the end of the string |

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.
parses a string representing a number in a configurable base and returns the integer
| num | a string representing a number |
| base | the base of the number |
| STRTOINT-ERROR | cannot parse string; unsupported base, etc |
