- FIND.RED - Recognition and search OBLIST functions
- -------------------------------------------------
- This is a loadable option [Load Find; in RLISP, (Load Find) in LISP].
- These functions take a string or id, and map the Symbol Table to
- collect a list of ids with Prefix or Suffix as given:
- FindPrefix(Key:{Id, String}):id-list Scan Symbol Table for prefix
- FindSuffix(Key:{Id, String}):id-list Scan Symbol Table for suffix
- Find(Pattern:{Id,String}):id-list Scan Symbol Table for matching string
- Thus X:=FindPrefix '!*; Finds all ids starting with *
- The 'GSORT' package is used to sort the list.
- The Pattern is a string, with special characters, prefixed by %, like the
- format string in PrintF; StringMatch(pattern,subject) is called:
- %% Match a % in subject string
- %? Match any one character
- %* Match any series of characters (0..n)
- Thus Find "*%*"; is equivalent to FindPrefix "*";
- Find "%**"; is equivalent to FindSuffix "*";
- Find "A%*B"; matches any string starting with A and ending with B.
