Hi Nick,

I'm not agree with you, because I use m4 now.
Such functionality was really useful together with include functionality.
For example, when I have errors with m4 it's hard to understand in
what line these errors occurred.
Why that ? IMHO, even if the script was generated via M4, even if the
"replacement" is done internally, you have exactly the same issues - if
you use replacements with multiple lines.
Actually with m4 is even better, as you see the intermediary script
version (you also see the script with all text processing done), so it
easy to spot errors.
m4 is not always convenient,
I should compile my configuration every time,
personally, I simply add it my "init.d" script, so the .cfg is
automatically built when "start" is done.
but I don't need all
power of m4, I need only substitutions.
m4 is not a panacea for all occasions.
Ok, it may be the case - on the other hand, using the over-powered tool
of M4 comes with no penalty ....and M4 is by default installed on all
distros..
This is my personal opinion on this.
Regards,
Bogdan

Summary: Substitutions in configuration file
Initial Comment:
This patch gives very useful feature - support to perform substitutions inside
the strings of config.
Work derived from the great parser enhancements made by Daniel-Constantin
Mierla to the sip-router project.
For example
!subst
perform substitutions inside the strings of config
!subst offers an easy way to search and replace inside strings before cfg
parsing. E.g.,:
!subst "/regexp/subst/flags"
flags is optional and can be: 'i' - ignore case; 'g' - global replacement
Example:
!subst "/DBPASSWD/xyz/"
modparam("acc", "db_url", "mysql://user:DBPASSWD@localhost/db")
will do the substitution of db password in db_url parameter value

Hello,
We do not feel such a patch would be very useful.
You can always implement such functionality with a more advanced tool, like
m4, instead of implementing all of this subst logic into the OpenSIPS
parser.
Regards,
Vlad
