I just found your question in my last month's archive of the list,
therefore I'm late in answering :-)
Three is no 'real' way to do what you want, because
you can not 'really' make macros depend on values of
a variable (as far as I know).
BUT you *can* write a 'toggle' (or a 'loop' with many values)
by letting each macro-call redefine the key ti the next call
(with two this toggles, but there is no real limit :-)
E.g. I did a toggle between English and German 'ispell'
in the compose screen because I run mutt *permanently* but
reply in both languages (and have the same high rate of
typos in both :-):
-------------- piece of .muttrc ------------------------
#
# 'toggler' in 'compose' for ispell dictionaries
# Output of the current 'setting' by "set ?<variable>"
#
# 'Actions'
macro compose _AX0 ":set ?ispell^M"
macro compose _AX1 ":set ispell=\042ispell -d american\042^M"
macro compose _AX2 ":set ispell=\042ispell -d ngerman\042^M"
# 'Rotators'
macro compose _A00 ":macro compose \\260 \042:push
\\042_A01\\042\\r\042^M_AX1_AX0"
macro compose _A01 ":macro compose \\260 \042:push
\\042_A00\\042\\r\042^M_AX2_AX0"
#
# Default setting:
set ispell="ispell -d ngerman"
# startup ° rotating _A*
macro compose \260 ":push '_A00'^M" "switch ispell language"
------------------------------------------------------------
First thing to know is, that I begin all the 'convoluted'
macros with an '_' underscore, and make them four chars long,
so I never hit them by accident.
The \260 is the little circle (degree '°'), which is above '^'
on my German Microsoft-Natural Keyboard.
To include a Doublequota in the Text of the macro I use \042.
And to include such a 'Definition by octal number' into the
Macro I have to double the Backslash.
To show the actual setting I 'appended' the extra macro '_AX0'
I already did the same thing for my 'index_format'
(about 10 different values) and a group of 12 'rotating' limits.
But those would need *very* long explanations to understand the
actual code-lines and are just logical extensions of the same idea.
The only extra idea was to create the 'default Action-Macro number _XX1'
by a folder hook, so the 'ring' of index-views can depend on the
actual folder mutt sees.
Hope that shows, what is possible with mutt, which has
no real 'programming' but ordinary textual macros.
Yours Stucki
