How can I extend the Emacs package align.el to make M-x align-entire
additionally align the if sub-expressions and opening curly-braces as
follows?:
if (x) { xi = -1; }
else (yyy) { yyyi = +1; }
should be aligned into
if (x) { xi = -1; }
else (yyy) { yyyi = +1; }
(the example needs to be displayed in fixed-width font to be
understandable)
Thanks,
Nordlöw

Perhaps try align-regexp.

Got it with command `align-entire'
with a customized `align-rules-list'.
Edited the regexp of `c-assignment': `[[{=]' instead of `='.
Then optional attributes
- Repeat:
- Boolean : on

The variable `align-rules-list' is really big. How can I easily change/
extend the part concerning c-assignment? Is there perhaps some variant
of add-to-list(), say modify-list-item(), that does just that?
Thanks again,

I didn't look at this. I thought you could just C-u M-x align-regexp
and it would prompt you for everything.

Don't know. Anyway, customization seems easier then
writing new code:
M-x customize-variable align-rules-list
C-s c-assignment
Then below you see the regexp-string, which matters.
[^-=!^&*+<>/|
]\(\s-*[-=!^&*+<>/|]*\)=\(\s-*\)\([^=
]\|$\)
In the middle a single, not parentised `=' - the char taken for indentation.
Simply extend expression here, replace `=' by `[{(=]' -
a group of signes. (Or any others you want indentation
work on...)
Then still two switches AFAIR.
Just below:
Set first attributes Value Menu to "Repeat:"
And again below `Bolean' to "on".
So it works for me.

Superb! Works for me! I am in now align heaven...
Emacs developers:
However I do think that the variable align-rules-list is too big. I
think it should be divided up into smaller pieces that can be
individually customized. If I save my customization of align-rules-
list I won't be affected by other changes made to it through updates
in the Emacs CVS repository.
Thank you very much,
Nordlöw
