[Ferm] $LINE variable expanded when declared

[Gian Piero Carrubba]

Hi all,

posting to the list because I didn't find an address for bug reporting.

I have a file containing definitions like the following:

    15 @def &limit_by($mode, $limit) =
    16   mod hashlimit
    17       hashlimit-mode  $mode
    18       hashlimit       $limit
    19       hashlimit-burst $limit
    20       hashlimit-name  @cat(@substr($FILEBNAME, 0, 11), ':', $LINE)
    21   ;

Whenever the function is invoked, $FILEBNAME is expanded to the basename 
of the calling file, but $LINE is always resolved to '20', so the lineno 
where it is declared instead of the lineno of the invoking script (as I 
wished).
Calling the function from the same file it is defined into doesn't help 
either:

     $ cat test
     1 @def &log($msg) =
     2    LOG log-prefix @cat('calling line: ', $msg, ' - expanded line: ', $LINE);
     3
     4 chain OUTPUT &log($LINE);

     $ /usr/sbin/ferm -n -l --slow test
     /sbin/iptables -t filter -P OUTPUT ACCEPT
     /sbin/iptables -t filter -F
     /sbin/iptables -t filter -X
     /sbin/iptables -t filter -A OUTPUT --jump LOG --log-prefix 'calling line: 4 - expanded line: 2'

This behaviour contradicts both what described in the manpage and what 
reported by the patch author [0].

Ferm 2.1 (Debian sid) here, but haven't see anything related in the 
commit logs I guess this also applies to trunk (maybe caused by commit 
dbbab34 ?).

Ciao,
Gian Piero.
