Announce: Template::Plugin::Lingua::EN::Inflect

I have written a simple plugin interface to Damien Conway's
Lingua::EN::Inflect module (basing the code on the autoformat plugin).

This allows you to do things like


[.%- USE infl = Lingua.EN.Inflect;
message = "There PL_V(was) NO(error).\nPL_ADJ(This) PL_N(error)
PL_V(was) fatal.";

message | inflect(number => 1);
message | inflect(number => 42);
"... and "; infl.ORD(9); "ly...";
-%]

and get nicely inflected messages like:

There was 1 error.
This error was fatal.
There were 42 errors.
These errors were fatal.
... and 9thly...


I will be uploading the module to CPAN later today but it is also
available from

http://andrew-ford.com/perl/tt2-inflect-plugin.html

The man page is included below.

Comments welcome.

Andrew

NAME
Template::Plugin::Lingua::EN::Inflect - Interface to Lingua::EN::Inflect
module

SYNOPSIS
[% USE infl = Lingua.EN.Inflect; -%]
[% FILTER inflect(number => 42); -%]
There PL_V(was) NO(error).
PL_ADJ(This) PL_N(error) PL_V(was) fatal.
[% END; -%]

[% "... and "; infl.ORD(9); "ly..." %]

# Output:
# There were 42 errors.
# These errors were fatal.
# ... and 9thly...

DESCRIPTION
The Lingua::EN::Inflect is an interface to Damian Conway's
Linua::EN::Inflect Perl module, which provides plural inflections,
"a"/"an" selection for English words, and manipulation of numbers as
words.

The plugin provides an 'inflect' filter, which can be used to
interpolate inflections in a string. The NUM() function set a persistent
default value to be used whenever an optional number argument is
omitted. The number to be used for a particular invocation of 'inflect'
can also be specified with a 'number' option.

For the full gory details of the inflection functionality refer to the
Lingua::EN::Inflect manual.

OBJECT METHODS
"infl.A($string, $opt_number)"
prepends the appropriate indefinite article to a word, depending on
its pronunciation. If the second argument is provided and its value
is numeric and not 1 then the value of the second argument is used
instead.

e.g. "infl.A("idea")" returns "an idea"

"AN($string, $opt_number)"
synonym for "A()"

"NO($string, $opt_arg)"
"NUM($string, $opt_arg)"
"NUMWORDS($string, $opt_arg)"
"ORD($number)"
"PART_PRES($string, $opt_arg)"
returns the present participle for a third person singluar verb

PART_PRES("runs"); # returns "running"

"PL($string, $opt_arg)"
returns the plural of a *singular* English noun, pronoun, verb or
adjective.

"PL_N($string, $opt_arg)"
returns the plural of a *singular* English noun or pronoun.

"PL_V($string, $opt_arg)"
returns the plural conjugation of the *singular* form of a
conjugated verb.

"PL_ADJ($string, $opt_arg)"
returns the plural form of a *singular* form of certain types of
adjectives.

"PL_eq($string, $opt_arg)"
"PL_N_eq($string, $opt_arg)"
"PL_V_eq($string, $opt_arg)"
"PL_ADJ_eq($string, $opt_arg)"
"classical($string, $opt_arg)"
"def_noun($string, $opt_arg)"
"def_verb($string, $opt_arg)"
"def_adj($string, $opt_arg)"
"def_a($string, $opt_arg)"
"def_an($string, $opt_arg)"
TODO
Finish off documenting the object methods.

Provide tests for all methods in the test suite.

It would also be nice to have methods that spelled out numbers that were
less than a certain threshold and that formatted large numbers with
commas, for example:

inflect("There PL_V(was) NO(error).", number => 0);
# outputs: "There were no errors."

inflect("There PL_V(was) NO(error).", number => 1);
# outputs: "There was one errors."

inflect("There PL_V(was) NO(error).", number => 3);
# outputs: "There were three errors."

inflect("There PL_V(was) NO(error).", number => 1042);
# outputs: "There were 1,042 errors."

This would require changes to the Lingua::EN::Inflect module.

AUTHOR
Andrew Ford <A.Ford [at] ford-mason> wrote the plugin code (basing it
heavily on the Template::Plugin::Autoformat code).

Damian Conway <damian [at] conway> wrote the Lingua::EN::Inflect module,
which does all the clever stuff.
