However, the user can enter actual Latex into the document (ERT – Evil Red Text, as Lyx calls it) on the occasions when it is needed. For example, I use Lyx quite a lot and I can’t think of any Latex tags, off hand. The user is protected from the actual markup language. Lyx sits on top of a well-established publishing markup language called Latex. To the novice they are both equivalent as they look the same on screen.Īs I said earlier, Lyx strikes a slightly different balance to that of a word processor when it comes to the relationship between layout and content.

To use an analogy, often, when teaching someone how to use a word-processor, it is difficult to convince them of the importance of using tabs as opposed to spaces. However, features such as extra spaces and carriage returns are interpreted literally by conversion programs, with potentially baffling results for the reader of the target document. Such inconsistencies might not even be apparent when editing the document.

In most word processors, the user is free to add formatting that has no real meaning in relation to the content. Ideally, the user shouldn’t be overly concerned with layout and formatting while he or she is creating the content.Īnother weakness of WYSIWYG becomes apparent on projects in which the finished document will need to be transformed from one format to another. The preceding example might seem somewhat contrived but a more common problem would be that a lot of people, such as myself, like to use a sans-serif font as a screen font while preferring the look of a serif font on the printed page. Another problem with this approach is that, in my experience, a procedure of this sort is apt to encourage errors to creep into the creative process.
Unfortunately, as you change the font, all of the document layout alters around it. I could solve this problem by using a more neutral font when editing and then change back to desired font for print out. What if I wanted to use an unusual font on part of the document? Within a word processor, I would have to actually edit using that font, regardless of its usability. I can highlight one weakness of this approach with an example: Most wordprocessors represent the other extreme as they attempt to give the user a WYSIWYG representation of the document while the user is editing it. When editing markup in this way, the user uses tags to specify the formatting, knowing that the finished document will look very different from the source code. Hand editing mark-up such as HTML in a text editor would be an extreme example of separation of content and formatting. The separation of content and formatting.
Where is shines is in the creation of documents such as reports, articles and books. Lyx probably isn’t the tool for every type of writing. The driving concepts behind Lyx’s approach are the separation of content from formatting and structured document creation. In truth, in an article of this length, I wouldn’t even be able to cover most of the new features of 1.5.0, so, I’ll give you an overview of some of the features that I make use of in my day to day use. Lyx is a very powerful program and contains too many features to list here. In this article, I’ll give an overview of Lyx and try to cover some of the new features that have been introduced in 1.5.0. Other users can, of course, build from source. The development team officially support builds for Linux, MacOSX and Windows. However, on the 21st of Feb 2007, the team released the first beta of 1.5.0. The current stable version of Lyx is the recently released 1.4.4. The creators of Lyx have coined the term WYSIWYM (what you see is what you mean) to summarise the approach that Lyx takes to document creation. Conceptually, it falls somewhere between a markup editor and a word processor. Lyx is an open source, structured document creation system.
