NAME

6       Class::MakeMethods::Docs::ToDo - Ideas, problems, and suggestions
7

SYNOPSIS

9       There are lots of things that could be done to improve this module.
10

DISTRIBUTION ISSUES

12       Issues about the distribution and supporting files, rather than the
13       code:
14
15   Documentation
16       •   Make sure that the documentation is broken up into appropriately-
17           sized chunks, and that people will know which section to look at.
18
19       •   As user questions arrive, add the answers as documentation points
20           or examples.
21
22       •   Assemble annotated examples and tutorials, and either link to or
23           distribute them.
24
25       •   Finish overhauling Template documentation.
26
27       •   Include Global and InsideOut uses in the EXAMPLES section
28
29       •   Template Internals: Finish documenting disk-based meta-method code-
30           caching.
31
32   Tests
33       •   Use Devel::Coverage to measure test coverage, and fill in missing
34           cases.
35
36       •   Finish tests for Standard and Composite modules.
37

GENERAL ISSUES

39       •   It does not appear to be possible to assign subroutine names to
40           closures within Perl. As a result, debugging output from Carp and
41           similar sources will show all generated methods as "ANON()" rather
42           than "YourClass::methodname()".
43
44           UPDATE: There now seem to be fixes for this which should be
45           integrated: See the new Sub::Name module and
46           http://perlmonks.org/index.pl?node_id=304883
47
48       •   For scalar methods (and others) it would be nice to have a simple
49           bounds-checking interface to approve or reject (with an exception)
50           new values that were passed in.
51
52           As pointed out by Terrence Brannon, the right interface to adopt is
53           probably that of Attribute::Types:
54
55             use Class::MakeMethods::Standard::Hash (
56               'scalar' => [ 'count' => { TYPE => 'INTEGER' } ],
57               'scalar' => [ 'name' => { TYPE => qr/^[A-Z]\w*$/ } ],
58               'scalar' => [ 'account' => { TYPE => &checksum_account_number } ]
59             );
60
61       •   Improve use of _diagnostic hooks for debugging. Add various "(Q)"
62           debug diagnostics.
63
64       •   Finish building Inheritable array and object accessors.
65
66       •   Finish building Composite::* packages.
67
68       •   Resolve DESTROY-time issues with Standard::Inheritable,
69           Composite::Inheritable, and Template::InsideOut.
70
71       •   Add slice and splice functionality to Standard::*:hash and
72           Composite::*:hash.
73

TEMPLATE CLASSES

75   Template::Generic
76       •   Allow untyped object accesors if "class" attribute is not set.
77           (Suggested in Jan-01 NY Perl Seminar discussion.)
78
79       •   Standardize naming templates for array, hash, other method types.
80
81           Deprecate verb_x methods? Or at last make them consistently
82           available both ways.
83
84           Make list methods consistent with hash_of_lists methods, in action,
85           and in name (x_verb).  Also for others (e.g., set_ clear_ boolean)
86
87       •   Should default object template provide auto-create behavior on
88           ->get()?
89
90       •   Generalize the "Generic:scalar -init_and_get" interface to support
91           memoizing values for other accessor types.
92
93       •   Consider adding hash each and array iterator methods, using a
94           closure to provide iteration.
95
96       •   Add support for tied arrays & scalars, a la tiedhash
97
98       •   Add string_multiple_index.
99
100       •   Extend index methods to support weak indexes with WeakRef. Perhaps
101           just have it accept a hash ref to use as the index, and then allow
102           people to pass in tied hashes?
103
104       •   Maybe make private or protected method croak if they were called by
105           a method_init method which was called by an outside package.
106
107           Not entirely clear what the right semantics or security precautions
108           are here...
109
110   Template::Generic Subclasses
111       •   Finish building code_or_scalar meta-method.
112
113       •   Finish building Class::MakeMethods::ClassInherit subclass.
114
115           Need to work out how to capture changes for non-scalar values. For
116           example, if a subclass inherits an array accessor and then pops it,
117           is there some way to provide them with copy-on-write?
118
119       •   Add enumerated string/number type.
120
121           Provide helper methods with map of associated values (ex $o->port =
122           80 ... $o->port_readable eq 'HTTP' ). Cf. code for earlier
123           unpublished 'lookup' method type.
124
125       •   For StructBuiltin:
126
127           Add -fatal flag to die if core func returns false / undef Add call
128           method to recall method with alternative arguments.  Add -nocall
129           flag to not call core func on new.
130
131       •   Replace ClassName:static_hash_classname with Class:indexed_string.
132
133   Template Internals
134       •   Figure out which modules, if any, should actually be using
135           AutoLoader.  Probably just Template::Generic?
136
137       •   Give users a way to do meta-method code-caching in Perl library
138           hierarchy, rather than in /tmp/auto or other user-specified
139           directory..
140
141           Provide mechanism for pre-generating these at install time.
142
143           Perhaps load these via do, rather than open/read/eval?
144
145           Perhaps pre-generate expanded libs with all of the -imports
146           resolved?
147
148       •   Support generating code files and loading them as needed.
149
150           This would be similar to Class::Classgen, except that we'd do the
151           generation at run-time the first time it was required, rather than
152           in a separate pass.
153
154           For example, given the following declaration:
155
156             package Foo::Bar;
157             Class::MakeMethods::Template::Hash->import(-codecache=>'auto', scalar=>'foo');
158
159           We should be able to write out the following file:
160
161             cat 'auto/Foo/Bar/methods-line-2.pl'
162             # NOTE: Generated for Foo::Bar by the Class::MakeMethods module.
163             # Changes made here will be lost when Foo::Bar is modified.
164             package Foo::Bar;
165             sub foo {
166               my $self = shift;
167               if ( scalar @_ ) {
168                 $self->{'foo'} = shift();
169               }
170               $self->{'foo'}
171             }
172
173           Then on subsequent uses, we can just re-load the generated code:
174
175             require "auto/Foo/Bar/methods-line-2.pl";
176
177           To do this, we need to:
178
179           •   Provide an option to select this if desired; maybe ...
180               import('-cache' => 'auto/', ...)?
181
182           •   Figure out which directory we can/should write into.
183
184           •   Re-evaluate the textual code templates, without generating the
185               closures. Substitute in any _STATIC_ATTR_ values. Make other
186               _ATTR_ values point to some public lookup table or package
187               scalar.
188
189           •   Notice if the source file (or Class::MakeMethods modules) has
190               been updated more recently than the generated file.
