one of the features of the epic editor that I really love is that it does what I expect it to do (at least most of the time). That is especially true for the delete-next-word command (Ctrl-Del). In EPIC this will delete any white space before an actual word without touching the word itself. Perfect.
However, other Eclipse editors don't do that. They will delete the word as well and I don't have any quick and easy way to get rid of the white space. This is at least true on my plaform, using gtk2.
So I asked in the pydev forums recently why their editor would not give me the desired behavior and part of the answer was that their editor simply inherits the behavior from eclipse. Of course, this brings up the question whether the EPIC editor is doing any special magic regarding the delete-next/previous-word commands?
Unfortunately, the platform (workbench) doesn't provide enough functionality for good word navigation independently of the syntax of a programming language (how is a word defined, after all?). EPIC's code mimics the behavior of the Java editor. Both EPIC and the Java editor contain extra code to implement the behavior you expect compared to the "raw" platform (e.g., the plain text editor).
Both EPIC's and Java editor's behavior is consistent with the other word navigation actions (in this case, "go to the next word's beginning", CTRL-right). If the other project(s) are not so consistent, that's a problem which they should fix. You can also argue that the Java editor is the gold standard to which all other editors should adhere unless there are important reasons for deviating.
