Diamond is a document editor for Mac OS X, minimalist in design yet flexible and very powerful, allowing you to create a fully customized user interface, as minimal or as complex as you want. Although on the surface it presents a unique and highly configurable document window, beneath the surface it is a fully equipped Mac application and when editing a document will behave exactly as you expect it to. If your are familiar with editing Rich Text documents in other Mac applications, your are already very familiar with Diamond.

In addition to its own format/extension of .dmd, Diamond reads and writes files in the RTF, RTFD, Text, and more...

Would not have posted this here if I'd been able to find a way to contact the developer on his site to report what appears to be a bug, viz., that the hot keys for raising and lowering the Backdrop don't work. Am running Snow Leopard under 10.6.3. This is a solid app that's worth following. Different feeling entirely than Hogbay Software's WriteRoom, probably the most popular of these minimalist environment writing apps. I use WriteRoom, but lost respect for its developer, Jesse Grossjean, when he dumped a crash-prone version of WriteRoom for iPhone for $4.99 on unsuspecting users in the Apple iTunes Store, then blithely ignored repeated and urgent requests for fixes from many users for months, though his site forum shows he's been aware of the problem for at least that long. (His excuse was that he was busy developing apps for the iPad. Insult to injury, that.) The experience fueled my interest in finding an alternative. Diamond's been around for a while, and with a few fixes, could be the heir apparent to WriteRoom, IMO.

Thanks for the feedback, email me at geoffreyalexander@me.com. Looking into issues with Snow Leopard, testing has been minimal on that platform so far, am going exclusive Snow Leopard on all my machines in about a week so I should have a fix soon. Thanks!

Lovely in its simplicity. Easy to use and to view on screen. I use a "paper" background to a page and it is very nice. I like the ability to format text. Only additional thing I would like is styling paragraphs so that I could have them, by default, indent and have space between them. I also have Ulysses (not used any more) and Scrivener (very nice program as well) but I find Diamond easy to open and use so use it more. The column format is great and makes working with text more accessible to me. I am very glad it has been shared.

Nice little editor, all that's been needed for many tasks.
What I don't like: if you activate Diamond via the Dock, it always opens a new empty window (fortunately it doesn't do that if you change programs via cmd-tab).
And I don't find the horizontal scrolling particularly useful - an option to use standard vertical scrolling would be nice. The page up/down arrows also don't work reliably (often those only adjust the view a few pixels).
"Undo" is also unreliable (e.g. the Homogenise feature is only undoable if you're lucky).
What's really missing is the stander "Recent files" menu.

Thanks for the review; Undo has not yet been implemented for a couple commands as you noted; I'm revising the Read Me to note the exceptions; these will be cleaned up in a near-future release. As for the "Recents" menu, I've been working on that on and off for some time; due to severe issues with the underlying Apple Doc system, Diamond docs (no matter what format you try to save them) don't register as saved documents. Hopefully I'll find that solution before my ulcers kill me. Keep tracking updates here and hopefully I can have your issues handled soon.

Diamond provides the ability, via preferences and other options, to set my work space environment to suit my workflow or better still, the particular way I like to work. By using the main space backdrop, it provides the ability to isolate as much, or as little, as one would like from the writing environment. I also like being able to use color, images or pictures for the document work space, as well as the main space backdrop. I currently use the developer provided “cardStock” image file for the document work space and the “brownPaper” image file for the main space backdrop, this combination works well for my purposes. These image files can be downloaded from the developer’s web site. If you’re so inclined, your own images or pictures can be used for these purposes as well. Diamond loads with the main space backdrop raised, lowering it allows a number of distractions to be, at least temporarily or for the current work session, minimized or eliminated. Another feature of Diamond that appeals to me, admitting it took a little getting used to at first and also mentioned in the program description, is it handles the documents in a horizontal column format, similar to Amar Sagoo’s Tofu for displaying documents in a newspaper style horizontal column format. The developer has also provided the ability to export your work to Apple Mail, Sticky Note or Entourage which, for me, has come in handy a number of times. Of course select all, copy & paste would probably also work. I rely on Diamond daily for a variety of tasks and it has always been up to the challenge. Diamond is actively developed and I have found the developer to be extremely responsive to questions, suggestions, requests and recommendations (constructive criticism). I’ve just scratched the surface of Diamond with this review, some things, like Diamond really need to be experienced, so download Diamond 3.1, give it a spin and see if it fits into your workflow.
