12 use Email::MIME::Kit;
13
14 my $kit = Email::MIME::Kit->new({ source => 'mkits/sample.mkit' });
15
16 my $email = $kit->assemble({
17 account => $new_signup,
18 verification_code => $token,
19 ... and any other template vars ...
20 });
21
22 $transport->send($email, { ... });
23
25 Email::MIME::Kit is a templating system for email messages. Instead of
26 trying to be yet another templating system for chunks of text, it makes
27 it easy to build complete email messages.
28
29 It handles the construction of multipart messages, text and HTML
30 alternatives, attachments, interpart linking, string encoding, and
31 parameter validation.
32
33 Although nearly every part of Email::MIME::Kit is a replaceable
34 component, the stock configuration is probably enough for most use. A
35 message kit will be stored as a directory that might look like this:
36
37 sample.mkit/
38 manifest.json
39 body.txt
40 body.html
41 logo.jpg
42
43 The manifest file tells Email::MIME::Kit how to put it all together,
44 and might look something like this:
45
46 {
47 "renderer": "TT",
48 "header": [
49 { "From": "WY Corp <noreplies@wy.example.com>" },
50 { "Subject": "Welcome aboard, [% recruit.name %]!" }
51 ],
52 "alternatives": [
53 { "type": "text/plain", "path": "body.txt" },
54 {
55 "type": "text/html",
56 "path": "body.html",
57 "container_type": "multipart/related",
58 "attachments": [ { "type": "image/jpeg", "path": "logo.jpg" } ]
59 }
60 ]
61 }
62
63 Inline images may be accessed with the function "cid_for", for example
64 to include the above logo.jpg:
65
66 <img style="margin: 0 auto" src="cid:[% cid_for("logo.jpg") %]">
67
68 Please note: the assembly of HTML documents as multipart/related bodies
69 may be simplified with an alternate assembler in the future.
70
71 The above manifest would build a multipart alternative message. GUI
72 mail clients would see a rendered HTML document with the logo graphic
73 visible from the attachment. Text mail clients would see the
74 plaintext.
75
76 Both the HTML and text parts would be rendered using the named
77 renderer, which here is Template-Toolkit.
78
79 The message would be assembled and returned as an Email::MIME object,
80 just as easily as suggested in the "SYNOPSIS" above.
81
83 In general, "it should all just work" ... starting in version v3.
84
85 Email::MIME::Kit assumes that any file read for the purpose of becoming
86 a "text/*"-type part is encoded in UTF-8. It will decode them and work
87 with their contents as text strings. Renderers will be passed text
88 strings to render, and so on. This, further, means that strings passed
89 to the "assemble" method for use in rendering should also be text
90 strings.
91
92 In older versions of Email::MIME::Kit, files read from disk were read
93 in raw mode and then handled as octet strings. Meanwhile, the
94 manifest's contents (and, thus, any templates stored as strings in the
95 manifest) were decoded into text strings. This could lead to serious
96 problems. For example: the manifest.json file might contain:
97
98 "header": [
99 { "Subject": "Message for [% customer_name %]" },
100 ...
101 ]
102
103 ...while a template on disk might contain:
104
105 Dear [% customer_name %],
106 ...
107
108 If the customer's name isn't ASCII, there was no right way to pass it
109 in. The template on disk would expect UTF-8, but the template in the
110 manifest would expect Unicode text. Users prior to v3 may have taken
111 strange steps to get around this problem, understanding that some
112 templates were treated differently than others. This means that some
113 review of kits is in order when upgrading from earlier versions of
114 Email::MIME::Kit.
