I am not sure if tmail will automagically fail over without C
extensions, but if you don't have the c extensions installed, it
_should_ just run in ruby fine by itself.

If you extract the tmail tar ball and get the lib/ directory with
tmail.rb in it and require that you should be fine.  Just nuke the ext
directory from memory.

Subject: [Tmail-talk] Reading From a UnixMbox file.
Message-ID: <38071.216.185.71.24.1241473147.squirrel@webmail.harte-lyne.ca>

I am trying to test a script that generates email using uses Rails
ActionMailer 2.3.2.  I have installed the TMail 1.2.3.1 gem.

The way that this works is this. In the script I dump the contents
of ActionMailer::Base.deliveries into a disk file:


    ActionMailer::Base.deliveries.each do |msg|
      fo = File.open('deliver.txt','a')
      fo.write(msg)
      fo.write("\n")
      fo.close
    end

To the best of my ability to determine, this creates a valid mbox
format file.  I might be wrong but according to what I have read,
the mbox format simply requires a blank line after each message.  A
message is deemed to begin with the 'From: ' header.

The contents of this disk file appear correct given the foregoing
expectation:

$ cat deliver.txt

I gather from the documentation that I should be able to read this
message back into a TMail::Mail object doing this:


>> mbox = TMail::UNIXMbox.new('deliver.txt', nil, true)
=> #<TMail::UNIXMbox:0x2abdae52cb00
@finalizer=#<Proc:0x00002abdabad57f8@/usr/lib64/ruby/gems/1.8/gems/tmail-1.2.3.1/lib/tmail/mailbox.rb:249>,
@readonly=true, @real=#<TMail::MhMailbox
/tmp/ruby_tmail_9702_0.657023759401038>, @closed=false,
@filename="deliver.txt">
>> mbox.each do |port|
?>   mail = TMAIL::Mail.new(port)
>>   puts mail.subject
>>   y mail.methods.sort
>> end
=> Mon May 04 17:11:07 -0400 2009

What I get is a time object and I see no mail message.

If I try this instead, taken from the example given in the
documentation:

>> mailbox = TMail::UNIXMbox.new('deliver.txt', nil, true)
=> #<TMail::UNIXMbox:0x2abdae4d6b10
@finalizer=#<Proc:0x00002abdabad57f8@/usr/lib64/ruby/gems/1.8/gems/tmail-1.2.3.1/lib/tmail/mailbox.rb:249>,
@readonly=true, @real=#<TMail::MhMailbox
/tmp/ruby_tmail_9702_0.0737049330962023>, @closed=false,
@filename="deliver.txt">
>>  @emails = []
=> []
>> @emails =  mailbox.each_port { |m| @emails << TMail::Mail.new(m) }
=> Mon May 04 17:36:07 -0400 2009
>> @emails.class
=> Time

Another time object is returned.  What is going on here. What am I
doing wrong?

Sorry for the repeat, but I lost the replies. Also, only one reply appears in 
the archives, which is odd, as I received three. Anyway, I asked:

I'm trying to install the native ruby tmail gem. http://tmail.rubyforge.org/ 
doesn't describe how to do this, that I could find, although it does say that 
this should work when a C compiler is not present.

Here's[1] the result of

  $ jruby -S gem install tmail

How do I force a pure ruby install in this case?

Btw, I also tried this on a Windows machine without a C compiler and it failed 
in exactly the same way.

[1]

Building native extensions.  This could take a while...
/home/marc/jruby/lib/ruby/1.8/mkmf.rb:7: JRuby does not support native 
extensions. Check wiki.jruby.org for alternatives. (NotImplementedError)

=========================

I'm trying to install a gem that requires tmail. To satisfy that requirement I 
need tmail installed. Because of the native extension, I can't install tmail 
for JRuby.

Installing locally isn't an option here, as I want to create a gem that will 
run under JRuby. The problem being that anyone installing my gem will have the 
same issue.

If the pure ruby gem install is not going to be fixed, which is what I presume 
from the lack of activity to fix it, which is fair enough, are there any 
objections to me forking tmail to provide a pure ruby install?
