/** Exception causes and external messages are passed as message lists which
|
|
have the following syntax:
|
|
|
|
message_list ::= single_message |
|
|
single_message separator message_list
|
|
|
|
separator ::= newline |
|
|
newline | separator
|
|
|
|
single_message ::= message_ID |
|
|
message_ID parameters
|
|
|
|
parameters ::= tab string |
|
|
tab string parameters
|
|
|
|
Message_IDs are looked up an external file and replaced by the message
|
|
text strings they are mapped to. The message text may contain the
|
|
following:
|
|
|
|
Parameter specifications: These are modelled after printf format
|
|
specifications and have one of the following forms:
|
|
|
|
%n!s! %n!d! %n!i! %n!u! %n!x! %n!X!
|
|
|
|
where n is the parameter number. The parameter number is indicated
|
|
explicitly to allow for the possibility that the parameter order may
|
|
change when the message text is translated into another language.
|
|
The final letter ('s', 'd', 'i', 'u', 'x', or 'X') indicates the form
|
|
of the parameter (string, integer, integer, unsigned integer, lowercase
|
|
hexadecimal, or uppercase hexadecimal, respectively). In addition
|
|
formating options such as precision available in sprintf, may be used.
|
|
So, to print the third argument as 5 digit unsigned number, with leading
|
|
zero's one could use:
|
|
%3!05u!
|
|
|
|
All of the arguments are actually strings. For forms that don't take
|
|
string input ('d', 'i', 'u', 'x', or 'X'), and atoi() conversion is done
|
|
on the string before formatting. In addition the form indicates to the
|
|
translater whether to expect a word or a number.
|
|
|
|
The strings are read in from XML. To to format the strings, use the
|
|
relavent XML escape sequences, such as follows:
|
|
|
|
[line feed]
|
|
	 [horizontal tab]
|
|
' [single quote]
|
|
" [double quote]
|
|
< [less than sign]
|
|
> [greater than sign]
|
|
|
|
After parameters have been inserted in the message text, the formatting
|
|
strings are replaced by their usual equivalents (newline and tab
|
|
respectively).
|
|
|
|
If a message_id cannot be found in the external file, a message text
|
|
is fabricated giving the message_id and the parameters (if any).
|
|
|
|
Separators (newlines) are preserved in the translated message list.
|
|
|
|
Expands message lists by looking up the message IDs and inserting
|
|
arguments into the retrieved messages.
|
|
|
|
N.B. The resulting string may be encoded in UTF-8 format (ISO 10646-1
|
|
Annex R) and SHOULD NOT BE ASSUMED TO BE ASCII.
