Hi there,
I have a serious problem with automatically setting a specific mode
for files depending on their contents.
Due to some good reason we had to insert this header into our Perl
script files:
#!/bin/sh
exec $IW_PERL -x -w -S $0 ${1+"$@"}
Now I no longer could place -*- cperl -*- into the first line because
this would confuse the execve system call which executes some of these
files.
Until now I know these ways to specify the mode for a file
automagically:
1. By extension -- Doesn't fit here because the perl scripts do not
have any extension.
2. By placing the above given line in the first nonempty line of the
file -- No longer possible.
3. Local Variable list at the end of the file -- Would work but looks
somewhat ugly.
4. Setup of interpreter-mode-alist Variable -- Doesn't work because
only the first line is processed by this mechanism.
Is their any other way to put the "-*- cperl -*-" line near the top of
the file and get it processed by some mode determination mechanism?
Any ideas would be welcome.
Thanks,
Adalbert Perbandt.
