Module: sip-router Branch: master Commit: 20cddb28e968d8e0f79a7910d3cc83fa6f40887f URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=20cddb2… Author: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Committer: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Date: Fri Apr 23 23:58:43 2010 +0200 cfg: extended preprocessor directives - you can define values for IDs - defined IDs are replaced at startup, during config parsing, e.g.,: $var(x) = 100 + MYINT; - is interpreted as: $var(x) = 100 + 123; - you can have multi-line defined IDs while($var(i)<5) { \ xlog("++++ $var(i)\n"); \ $var(i) = $var(i) + 1; \ } - then in routing block route { ... IDLOOP ... } - new preprocessor directive - perform substitutions inside the strings of config (not that define is replacing only IDs - alphanumeric tokens not enclosed in quotes) - #!subst offers an easy way to search and replace inside strings before cfg parsing. E.g.,: modparam("acc", "db_url", "mysql://user:DBPASSWD@localhost/db") - will do the substitution of db password in db_url parameter value - number of allowed defines set to 256 - credits to Andrei for quick hints on ID defines - notes: - multilines defines are reduced to single line, so line counter should be fine - column counter goes inside the define value, but you have to omit the \ and CR for the accurate inside-define position --- cfg.lex | 137 +++++++++++++++++++++++++++++++++++++++++++++++++++++---------- cfg.y | 8 ++++ ppcfg.c | 116 +++++++++++++++++++++++++++++++++++++++++++++++++++++ ppcfg.h | 30 ++++++++++++++ 4 files changed, 270 insertions(+), 21 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=20c…
