Python and Regular Expressions

[Richard Lamboj]

Hello,

i want to parse this String:

version 3.5.1 {

$pid_dir = /opt/samba-3.5.1/var/locks/
$bin_dir = /opt/samba-3.5.1/bin/

service smbd {
bin = ${bin_dir}smbd -D
pid = ${pid_dir}smbd.pid
}
service nmbd {
bin = ${bin_dir}nmbd -D
pid = ${pid_dir}nmbd.pid
}
service winbindd {
bin = ${bin_dir}winbindd -D
pid = ${pid_dir}winbindd.pid
}
}

version 3.2.14 {

$pid_dir = /opt/samba-3.5.1/var/locks/
$bin_dir = /opt/samba-3.5.1/bin/

service smbd {
bin = ${bin_dir}smbd -D
pid = ${pid_dir}smbd.pid
}
service nmbd {
bin = ${bin_dir}nmbd -D
pid = ${pid_dir}nmbd.pid
}
service winbindd {
bin = ${bin_dir}winbindd -D
pid = ${pid_dir}winbindd.pid
}
}

Step 1:

version 3.2.14 {

$pid_dir = /opt/samba-3.5.1/var/locks/
$bin_dir = /opt/samba-3.5.1/bin/

service smbd {
bin = ${bin_dir}smbd -D
pid = ${pid_dir}smbd.pid
}
service nmbd {
bin = ${bin_dir}nmbd -D
pid = ${pid_dir}nmbd.pid
}
service winbindd {
bin = ${bin_dir}winbindd -D
pid = ${pid_dir}winbindd.pid
}
}

Step 2:
service smbd {
bin = ${bin_dir}smbd -D
pid = ${pid_dir}smbd.pid
}
Step 3:
$pid_dir = /opt/samba-3.5.1/var/locks/
$bin_dir = /opt/samba-3.5.1/bin/

Step 4:
bin = ${bin_dir}smbd -D
pid = ${pid_dir}smbd.pid

My Regular Expressions:
version[\s]*[\w\.]*[\s]*\{[\w\s\n\t\{\}=\$\.\-_\/]*\}
service[\s]*[\w]*[\s]*\{([\n\s\w\=]*(\$\{[\w_]*\})*[\w\s\-=\.]*)*\}

I think it was no good Solution. I'am trying with Groups:
(service[\s\w]*)\{([\n\w\s=\$\-_\.]*)
but this part makes Problems: ${bin_dir}

Kind Regards

Richi

I think you'd be better writing a specific parser here. Paul McGuire's
PyParsing package might help:

My 2 cents.
