HandleIntegerSModifier - Handle the integer 's' modifier. This adds the letter 's' to the string if the value is not 1. This is used in cases like this: "you idiot, you have %4 parameter%s4!".

HandleOrdinalModifier - Handle the integer 'ord' modifier. This prints the ordinal form of the given integer, with 1 corresponding to the first ordinal. Currently this is hard-coded to use the English form.

HandlePluralModifier - Handle the integer 'plural' modifier. This is used for complex plural forms, or in languages where all plurals are complex. The syntax is: plural{cond1:form1|cond2:form2|:form3}, where condn are conditions that are tested in order, the form corresponding to the first that applies being emitted. The empty condition is always true, making the last form a default case. Conditions are simple boolean expressions, where n is the number argument. Here are the rules. condition := expression | empty empty := -> always true expression := numeric [',' expression] -> logical or numeric := range -> true if n in range | '' number '=' range -> true if n % number in range range := number | '[' number ',' number ']' -> ranges are inclusive both ends
Here are some examples from the GNU gettext manual written in this form: English: {1:form0|:form1} Latvian: {0:form2|%100=11,%10=0,%10=[2,9]:form1|:form0} Gaeilge: {1:form0|2:form1|:form2} Romanian: {1:form0|0,%100=[1,19]:form1|:form2} Lithuanian: {%10=0,%100=[10,19]:form2|%10=1:form0|:form1} Russian (requires repeated form): {%100=[11,14]:form2|%10=1:form0|%10=[2,4]:form1|:form2} Slovak {1:form0|[2,4]:form1|:form2} Polish (requires repeated form): {1:form0|%100=[10,20]:form2|%10=[2,4]:form1|:form2}

HandleSelectModifier - Handle the integer 'select' modifier. This is used like this: select{foo|bar|baz}2. This means that the integer argument "%2" has a value from 0-2. If the value is 0, the diagnostic prints 'foo'. If the value is 1, it prints 'bar'. If it has the value 2, it prints 'baz'. This is very useful for certain classes of variant diagnostics.
