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… _______________________________________________ sr-dev mailing list sr-dev(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
