I am wondering part from emacs, vi and othe unix/unix like editors , why does KDE has kate, kedit, kwrite?
Is there any significant difference between them?

to give the end user an option
nothing more nothing less
why only have 1 or 2 apps to choose from when you can have an abundance of apps to choose from thats what makes linux all that much better..

They each adress a different need and skill level.
emacs and vi are for one thing, kate and kwrite are completely unsuitable for some things.

And more importantly, sometimes you want something really lightweight to just read something, or times you want something bigger to do some serious writing.
It's all up to personal preference in the end

Surely, u r right, is there any significant difference between them apart from GUI? It would have made some sense to me id they were pico , emacs or vi because of the diiferent way they work.
All KDE editors seems similar to me except for the interface.
Please correct me if I am wrong.

Kate and KWrite actual use most of the same code, but their interfaces are very different. Kate is for more advanced stuff, and is aimed at the programmer. ( Its also KDevelop's default editor ). While KWrite is aimed in a similar vein to KEdit, but can use some of Kates advanced features such as text high-lighting.

The reason KEdit and KWrite both exist at the moment is that the new code in KWrite does not yet support right to left languages. So KEdit may disappear in a future version, although this is not definate as it is a lot smaller, and loads quicker.

Yep, unlike windoze, open source gives us all a choice.........

Kate is a programmers Editor. You can switch from the editing more ( which is syntax highted and actuall the Kwrite part) and you have command mode for compilation and then directory sturcture for view files.
That makes it an excellent tool.
KEDIT not much comment on it. It is just a matter of choice. I hope you can configure your apps to install just want you need right?

KEdit: Just an editor, nothing special...
KWrite: Highlights code, more programming stuff
Kate: Some sort of extension to Kwrite which gives you the oppertunity to run commands from the
commandline and easily keep a list of docs open,...

Kate is really my favorite, since it is a great tool for shell scripting. I don't like its Highlighting for java though, in that case I prefer emacs...

You can edit its highlighting by altering the xml file it uses. Plus the preferences tab Highlighting textstyles under schemas. You can also extend its highlighting capabilities by writing your xmls for new languages or whatever. It will automatically add them to its menu's for you, as well as change to it when the correct extension/mime is used.

With textpad as the extremely-lightweight (and poor) editor, and wordpad as the slightly better. But I wouldn't know so much about them, because when I have to code on windows I use either the editor in MVS, or TextPad, which despite the name isn't a microsoft product.
