reference the folder name in a folder-hook push command

[Yubin Ruan]

Hi,

I have a folder hook like this:

folder-hook =somembox 'push "!touch /tmp/\1-touched\n"'

where I would like to create a file "/tmp/somebox-touched" when I select and
enter a mailbox. As you can see, \1 here should represent the name of the mbox
(as in many Regex). Is there a way to do this so that I do not have to write
rules for all the mbox one by one?

(actually I just want to pass as argument the name of a mbox to some external
shell command)


Regards,
Yubin

Like that:

folder-hook . 'set my_oldrecord=$record; set record=^; set my_folder=$record; set record=$my_oldrecord'
folder-hook . 'push "!touch /tmp/${my_folder}-touched\n"'

Thanks! I didn't know that ^ represent the current folder name. A greate trick
;-)

Thanks for sharing such an interesting approach. How can it be extended
to remove the '=' starting character? I've tried to do following:

folder-hook . 'set my_oldrecord=$record; set record=^; set my_folder=`echo $record | sed s/=//`; set record=$my_oldrecord'

But unfortunately it doesn't work for some reason.

The best I could come up with:

folder-hook . 'set my_oldrecord=$record; set record=^; set my_folder=$record; set record=$my_oldrecord'
folder-hook . 'push "!touch /tmp/$(echo ${my_folder} | sed 's,^=,,)-touched\n"'

The reason the solution you tried doesn't work is probably because
mutt performs shell substitution before parsing the line as said in
the manual:

"It is also possible to substitute the output of a Unix command in an
initialization file. This is accomplished by enclosing the command in
backticks (``). In Example 3.5, "Using external command's output in
configuration files", the output of the Unix command "uname -a" will
be substituted before the line is parsed."

So what shell sees is:

$ echo | sed s/=//

Thank you for suggestion and explanation, but do I understand right that
there is no way to create internal mutt variable ($my_foo) as
modification of another one ($my_bar)?

None that I'm aware of.
