Provide numerical argument to indent-rigidly-right

Provide numerical argument to indent-rigidly-right

[Andreas Röhler]

Hi,

what about providing a numerical argument to indent-rigidly-right

Like this:

(defun ar-indent-rigidly-right (beg end times)
   "Indent all lines between BEG and END rightward by TIMES space(s)."
   (interactive "r\np")
   (dotimes (i times nil)
     (progn (indent-rigidly
         beg end
         (if (eq (current-bidi-paragraph-direction) 'right-to-left) -1 
1)))))

Best,

Andreas

What's wrong with `indent-rigidly'?

Here M-x indent-rigidly RET doesn't indent at all, but sends a message:

Indent region with <left>, <right>, S-<left>, or S-<right>.


That's not as simple as it could be.

Also, if once selected right, not being asked next time. How to indent 
left then?

Probably there is a docu...

However, IMO a command indenting left or right should not need much 
docu, it should just do it.

Thus indent-rigidly seems not first choice as a caller.

Try calling it with a prefix arg (including a negative one)

Calling with negative arg

M-- 4 indent-rigidly RET has no effect here. Bug?

Also

docstring says:


If called interactively with no prefix argument, activate a
transient mode in which the indentation can be adjusted interactively
by typing <left>, <right>, S-<left>, or S-<right>.
Typing any other key exits this mode, and this key is then
acted upon as normally.


That's too complex for such a simple thing.

Sounds like it: it should strip (upto) 4 spaces from the beginning of
each line in the region.

`M-x report-emacs-bug` if it doesn't.

Only if there are spaces at the beginning of each line.

That's what I meant by "upto", indeed.

Well, if "upto" yields zero spaces, then the OP will think that
"nothing happened".

Works fine in emacs -Q

Turns out had a bad key-setting in my init, which blocked all negative 
prefixing:

Bad: (global-set-key [(meta ?-)] 'some-command)


Thanks all,

Did you select the text to outdent (i.e., active
region)?  Did you use `M-- 4 C-x TAB'?

If not, there's your problem.
If yes, `M-x report-emacs-bug'.

Is using a prefix arg too complex?  You're not
obliged to use incremental indenting/outdenting.
