6 Pod::Elemental::PerlMunger - a thing that takes a string of Perl and
7 rewrites its documentation
8
10 version 0.200006
11
13 This role is to be included in classes that rewrite the documentation
14 of a Perl document, stripping out all the Pod, munging it, and
15 replacing it into the Perl.
16
17 The only relevant method is "munge_perl_string", which must be
18 implemented with a different interface than will be exposed.
19
20 When calling the "munge_perl_string" method, arguments should be passed
21 like this:
22
23 $object->munge_perl_string($perl_string, \%arg);
24
25 $perl_string should be a character string containing Perl source code.
26
27 %arg may contain any input for the underlying procedure. Defined keys
28 for %arg are:
29
30 filename
31 the name of the file whose contents are being munged; optional,
32 used for error messages
33
34 no_strip_bom
35 If given, the BOM character (U+FEFF) won't be stripped from the
36 input. Probably best to leave this one off.
37
38 The method will return a character string containing the rewritten and
39 combined document.
40
41 Classes including this role must implement a "munge_perl_string" that
42 expects to be called like this:
43
44 $object->munge_perl_string(\%doc, \%arg);
45
46 %doc will have two entries:
47
48 ppi - a PPI::Document of the Perl document with all its Pod removed
49 pod - a Pod::Elemental::Document with no transformations yet performed
50
51 This "munge_perl_string" method should return a hashref in the same
52 format as %doc.
53
55 replacer
56 The replacer is either a method name or code reference used to produces
57 PPI elements used to replace removed Pod. By default, it is
58 "replace_with_nothing", which just removes Pod tokens entirely. This
59 means that the line numbers of the code in the newly-produced document
60 are changed, if the Pod had been interleaved with the code.
61
62 See also "replace_with_comment" and "replace_with_blank".
63
64 If no further code follows the Pod being replaced, "post_code_replacer"
65 is used instead.
66
67 post_code_replacer
68 This attribute is used just like "replacer", and defaults to its value,
69 but is used for building replacements for Pod removed after the last
70 hunk of code. The idea is that if you're only concerned about altering
71 your code's line numbers, you can stop replacing stuff after there's no
72 more code to be affected.
73
75 replace_with_nothing
76 This method returns nothing. It's the default "replacer". It's not
77 very interesting.
78
79 replace_with_comment
80 This replacer replaces removed Pod elements with a comment containing
81 their text. In other words:
82
83 =head1 A header!
84
85 This is great!
86
87 =cut
88
89 ...is replaced with:
90
91 # =head1 A header!
92 #
93 # This is great!
94 #
95 # =cut
96
97 replace_with_blank
98 This replacer replaces removed Pod elements with vertical whitespace of
99 equal line count. In other words:
100
101 =head1 A header!
102
103 This is great!
104
105 =cut
106
107 ...is replaced with five blank lines.
