I happened to have some Perl code lying around which sends an email by logging into by Gmail account and sending my email through Gmail. This is nice because I don’t have to run my own mail server, and if I can successfully send an email from my Gmail account and it doesn’t get eaten as spam or whatever, I know it will also work when my application sends an email.
Personally I don’t care what language a useful library is written in as long as I can really easily call it from Arc. So here’s what a Perl program embedded in Arc looks like, at least when using my template hack:
(= gmailprog ‡ use strict; use MIME::Lite; use Net::SMTP::TLS; my $msg = MIME::Lite->new( From => «from», To => «to», Subject => «subject», Type => 'TEXT', Data => «message» )->as_string(); my $mailer = new Net::SMTP::TLS( "smtp.gmail.com", Port => 587, User => «user», Password => «password»); $mailer->mail(«user»); $mailer->to(«to»); $mailer->data; $mailer->datasend($msg); $mailer->dataend; $mailer->quit; ‡) (def sendgmail (data) (thread (fromstring (gmailprog strperl:data) (system "perl"))))
The ‡...‡ hack constructs a template, which is filled in by passing it a table (or a table-like object that can be called with a key to return a value) to fill in the field values.
strperl converts an Arc string to a Perl string literal, carefully escaping quote and backslash characters as needed. Composing the table object
data passed to
strperl means that a data value such as “what's that?” will be inserted into the template as a Perl string like
'what\'s that?'. I run the whole thing in a separate thread, since it can take a few seconds to connect to Gmail.
sendgmail with a table containing your Gmail account name and password, and the From, To, Subject, and text of your email message:
(sendgmail (obj user "andrew.wilcox" ; put your Gmail account name here password "xxxsecret" ; and your Gmail password here from "Andrew Wilcox <[email protected]>" to "[email protected]" subject "Greetings Earthling!" message "Press the green button... press it now..."))
You’ll need Perl and the Perl modules
Net::SMTP::TLS. You can check if you have these modules installed by typing at the command line:
$ perl -MMIME::Lite -e '' $ perl -MNet::SMTP::TLS -e '' $
If you have the modules installed, Perl will print nothing (no news is good news), otherwise you’ll get an error. For information on how to install the modules, see How do I install Perl modules?
Then you’ll need this hack, sendgmail0.arc, and the hacks it relies on: scheme-values, ac, span, template, and toperl.
Or, using the hackinator:
$ hack \ ycombinator.com/arc/arc3.1.tar \ awwx.ws/scheme-values0.patch \ awwx.ws/ac0.patch \ awwx.ws/ac1.arc \ awwx.ws/span0.arc \ awwx.ws/template2.arc \ awwx.ws/toperl0.arc \ awwx.ws/sendgmail0.arc
