    <p>I have a recursive problem that is not returning as I expect and I'm not sure how to change the function.</p> <p>I would like an array containing both strings and arrays that derive from a chunk of text that is separated by boundaries defined in the text. The first pass works, but the second pass doesn't seem to correctly turn strings containing the boundary keyword into arrays and have them replace themselves in the parent array.</p> <p>Recursion functions:</p> <pre><code>def separate(text,boundary = nil) # returns array of strings and arrays containing all of the parts of the email textList = [] if !boundary #look in the email for "boundary= X" text.scan(/(?&lt;=boundary=).*/) do |bound| textList = recursiveSplit(text,bound) end end if boundary textList = recursiveSplit(text,boundary) end puts textList.count puts '\n' puts textList.inspect return textList end def recursiveSplit(chunk,boundary) if chunk.is_a? String searchString = "--" + boundary ar = chunk.split(searchString) return ar elsif chunk.is_a? Array chunk do |bit| recursiveSplit(bit,boundary); end end end </code></pre> <p>Example of text variable:</p> <pre><code>MIME-Version: 1.0 Received: by 10.112.170.40 with HTTP; Fri, 3 May 2013 05:08:21 -0700 (PDT) Date: Fri, 3 May 2013 08:08:21 -0400 Delivered-To: me@gmail.com Message-ID: &lt;CADPp44E47syuXvP1K-aemhcU7vdSijZkfKLu-74QPWs9U9551Q@mail.gmail.com&gt; Subject: MiB 5/3/13 7:43AM (EST) From: Me &lt;me@gmail.com&gt; To: Someone &lt;someone@aol.com&gt; Content-Type: multipart/mixed; boundary=BNDRY1 --BNDRY1 Content-Type: multipart/alternative; boundary=BNDRY2 --BNDRY2 Content-Type: text/plain; charset=ISO-8859-1 -TEXT STUFF HERE.

    2. CO@BjoernRennhak it's what happens when you "view original" a gmail email. It is then saved as a .txt file. I have changed some values for readability and anonymity.

    3. COThe boundaries you try to extract seem to be the usual structure you find in e.g. mbox or maildir files. I am wondering if you can use a proper library instead of custom scripting this to ensure maintainability and avoiding re-inventing the wheel. Why don't you try to use e.g. https://github.com/mikel/mail on it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
