The example you provided is the method I used -- once you get used to the odd
(but necessary) syntax, the syntax doesn't seem as bad.
Here's an example of some code that is similar to what I've done (although I
have more than 50 macros defined in my current source). The m4 source is
copied to the SIP Proxy Server (in this example, a development host) and the
following command is executed to generate the configuration:
$ m4 -DDEV config.m4 > config.cfg
--------------------------------
define(`ROUTE_MAIN', 0)
define(`_OPENSER_IP',`regexp(esyscmd(`hostname -i'),`\<.+\>',\&)')
define(`_OPENSER_PORT',`5060')
define(`_OPENSER_HOST',`regexp(esyscmd(`hostname -f'),`\<.+\>',\&)')
ifdef(`DEV',`
define(`OPENSER_NAME',`OPENSER (Development)')
define(`DEBUG_LEVEL',`3')
')
ifdef(`QA',`
define(`OPENSER_NAME',`OPENSER (Q`'A)')
define(`DEBUG_LEVEL',`3')
')
debug=DEBUG_LEVEL # -3 (L_ALERT) to 5 (L_DBG)
fork=no
log_stderror=no # do not print to stderr, if yes, syslog will be disabled
log_facility=LOG_LOCAL0
check_via=no # (cmd. line: -v)
dns=no # (cmd. line: -r)
rev_dns=no # (cmd. line: -R)
listen=_OPENSER_IP
port=_OPENSER_PORT
children=4
alias="OPENSER_NAME"
alias="_OPENSER_HOST"
route[ROUTE_MAIN] {
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
return;
};
if (msg:len > max_len) {
sl_send_reply("513", "Message too big");
return;
};
if (method == "INVITE" || method == "CANCEL") {
#
# Ensure a P-Charging-Vector header is present.
#
if (! is_present_hf("P-Charging-Vector")) {
$var(uuid) = $ci + $Ts + "_OPENSER_IP";
append_hf("P-Charging-Vector:
icid-value=$(var(uuid){s.md5})\r\n");
}
ifdef(`DEV',`
#
# Special rules for use in development.
#
...
')
...
}
...
}

Subject: RE: [OpenSIPS-Users] Include
Thanks Kevin!
I've started using m4 as Iñaki showed me yesterday, basically for setting
parameters on different systems. This I've already implemented and using
"happily ever after". :-)
Is there a better way of using M4 for bigger pieces of code, than the example
below:
divert(-1)
define(`ROUTE1',
`route[1] {
xlog("L_NOTICE", "We are now in route1\n");
}
')
divert(0)dnl
Thanks,

Not only the cleverest, I think it's the best!
I maintain the configuration for 12 SIP Proxies (using OpenSER) and I don't
need 12 different configuration files. A number of macros transform one m4
file into one of 12 different configuration files with the stroke of a short
command line.
I'd be happy to help provide some help to get you started ...

Hi Matti,
no, there is no other solution - using M4 is the cleverest solution ;)

Bogdan
