From 4515bdba4f56b298e62150ffe24608ba1a42e7da Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Thu, 11 Nov 1999 13:55:39 +0000 Subject: [PATCH] Fixed order of arguments for function call. Enumeration types should work once CF_ENUM() is ready. Created test.conf for testing of filters. (I'm currently thinking about ./tests in root directory which will just fire all available tests...) --- filter/config.Y | 39 ++++++++---------------- filter/test.conf | 78 ++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 90 insertions(+), 27 deletions(-) create mode 100644 filter/test.conf diff --git a/filter/config.Y b/filter/config.Y index 5c8977cf..4fe14731 100644 --- a/filter/config.Y +++ b/filter/config.Y @@ -8,7 +8,6 @@ FIXME (nonurgent): define keyword FIXME: whole system of paths, path ~ string, path.prepend(), path.originate FIXME: create community lists - FIXME: enumerational types FIXME: write access to dynamic attributes. */ @@ -41,9 +40,9 @@ CF_KEYWORDS(FUNCTION, PRINT, PRINTN, CONST, %nonassoc THEN %nonassoc ELSE -%type term block cmds cmd function_body constant print_one print_list var_list var_listn any_dynamic enums +%type term block cmds cmd function_body constant print_one print_list var_list var_listn any_dynamic %type filter filter_body -%type type break_command pair enum_rts +%type type break_command pair %type set_item set_items switch_body %type set_atom prefix prefix_s ipa %type decls declsn one_decl function_params @@ -103,8 +102,8 @@ decls: /* EMPTY */ { $$ = NULL; } /* Declarations that have no ';' at the end. */ declsn: one_decl { $$ = $1; } | declsn ';' one_decl { - $$ = $3; - $$->aux = (int) $1; + $$ = $1; + $$->aux = (int) $3; } ; @@ -229,27 +228,6 @@ switch_body: /* EMPTY */ { $$ = NULL; } } ; -enum_rts: - RTSDUMMY { $$ = 0; } - | RTSSTATIC { $$ = 1; } - | RTSINHERIT { $$ = 2; } - | RTSDEVICE { $$ = 3; } - | RTSSTATIC_DEVICE { $$ = 4; } - | RTSREDIRECT { $$ = 5; } - | RTSRIP { $$ = 6; } - | RTSRIP_EXT { $$ = 7; } - | RTSOSPF { $$ = 8; } - | RTSOSPF_EXT { $$ = 9; } - | RTSOSPF_IA { $$ = 10; } - | RTSOSPF_BOUNDARY { $$ = 11; } - | RTSBGP { $$ = 12; } - | RTSPIPE { $$ = 13; } - ; - -enums: - enum_rts { $$ = f_new_inst(); $$->code = 'c'; $$->a1.i = T_ENUM_RTS; $$->a2.i = $1; } - ; - constant: CONST '(' expr ')' { $$ = f_new_inst(); $$->code = 'c'; $$->a1.i = T_INT; $$->a2.i = $3; } | NUM { $$ = f_new_inst(); $$->code = 'c'; $$->a1.i = T_INT; $$->a2.i = $1; } @@ -260,7 +238,6 @@ constant: | ipa { NEW_F_VAL; $$ = f_new_inst(); $$->code = 'C'; $$->a1.p = val; *val = $1; } | prefix_s {NEW_F_VAL; $$ = f_new_inst(); $$->code = 'C'; $$->a1.p = val; *val = $1; } | '[' set_items ']' { printf( "We've got a set here..." ); $$ = f_new_inst(); $$->code = 'c'; $$->a1.i = T_SET; $$->a2.p = build_tree($2); printf( "ook\n" ); } - | enums { $$ = $1; } ; any_dynamic: @@ -285,6 +262,13 @@ term: | SYM { $$ = f_new_inst(); switch ($1->class) { + case 0: /* This should better be an enum */ + $$->code = 'c'; + $$->a1.i = $1->aux; + if (($$->a1.i < T_ENUM_LO) || ($$->a1.i > T_ENUM_HI)) + cf_error("You used symbol and it was not enum.\n"); + $$->a2.i = (int) $1->aux2; + break; case SYM_VARIABLE | T_INT: case SYM_VARIABLE | T_PAIR: case SYM_VARIABLE | T_PREFIX: @@ -296,6 +280,7 @@ term: cf_error("Can not use this class of symbol (%s,%x) as variable.", $1->name, $1->class ); } } + | RTA '.'
