How do I implement recursive definitions in regex
for 'c' functions?
For e.g
KEY "DELETED|SINCE "date"|"FROM "string
"|NOT "KEY"|"OR "KEY" "KEY"|
("KEY"( "KEY")* )"
I cannot use recursive definitions when using a #define
I defined it in the following manner(without much success!)
#define KEY_ALONE "DELETED|SINCE "date"|"FROM "string
#define KEY_SET "NOT "KEY_ALONE"| OR "KEY_ALONE"
"KEY_ALONE"|"KEY_ALONE"("KEY_ALONE")*"
However, this code does not run for combinations like
1. NOT NOT DELETED
2. NOT OR DELETED FROM "xyz"
3. OR OR DELETED FROM "xyz" SINCE "5-01-01"
4. OR OR NOT DELETED FROM "xyz" NOT SINCE "5-01-01"
5. OR DELETED OR FROM "xyz" SINCE "5-01-01"
