XEmacs questions

filburt1 · 04-23-2004, 02:36 PM

If you can answer even one of these questions, I would greatly appreciate it. These questions are all for C++.

How can I display line numbers in the gutter?
What is the option for deleting or overwriting text that is selected (i.e., when text is selected, Delete deletes the selection and any other key overwrites it)?
How can I always indent four spaces, no exceptions? i.e., I don't want something like this:
Code:
```
void someLongFooName(int foo,
                     long bar)
```
but rather
Code:
```
void someLongFooName(int foo,
        long bar)
```
or
Code:
```
void someLongFooName(int foo,
    long bar)
```
Moreover, the indenting should never be relative to any preceeding line.
How do I indent and outdent a selection?

And there was me thinking they were xemacs related ... :}

edit .emacs (or xemacs if that's what xemacs cllas it)
(column-number-mode t)

No idea, but I find both of your suggestions ugly,
they make no sense in the term of logical layout of
the function definition.

What would you think it should be using, then?
If you don't like the indentation feature, turn the
C++ mode off ...

M-x text-mode

1. That displays the numbers in the side gutter and not the bottom status bar?
3. The problem is that the indenting is very unpredictable. I simply want to be able to press tab and have an indent exactly four spaces further than the previous, and always starting at the first column, a la

Code:

etc.

Sorry then, I don't use xemacs, and in emacs it displays it at the bottom.

Doesn't xemacs do that in text-mode?
You cna easily change the default-tab width

(setq default-tab-width 4)

Well I have no idea what I'm doing then...I manually enable syntax highlighting to get color coding, and the tab is completely unpredictable. The selection problems are also incredibly frustrating.

I'm not sure whether you got the part about M-x text-mode...

All you need to do to get rid of the "erratic tabbing" (I find
it quite sensible) is to switch to text-mode ... and I'm sure
that there's a more "normal GUI" mode for highlighting and
deletion available ... in emacs you just use C-w to "delete" a
section of text.

I don't know why you would want to change xemacs's amazing indenting off... it does it all for you and it is a great way to find { } errors and such... (just tab every line and it indents properly... I have been helped countless times because of it's indenting...

I would like the feature if I knew it would do exactly what I wanted.

Line numbers don't have to be that hard. in options, you can select line and column numbers, then go to the save to init file option in the options menu. As for the tab question, I thought a tab was already set at 4 spaces, anyways.
