awk: speed improvements

2020-08-01T10:31:22+00:00

Improve performance in certain cases at the cost of an additional 144 bytes in the binary. - Reinstate (and fix) the original code to speed up assignment of a temporary string to a variable. - Replace use of xasprintf() for string concatentation with explicit string manipulation. This could be faster still if Windows had an optimised stpcpy(). The enhancement is not enabled by default. This test case: BEGIN{while(++i<30000) s=s i} is 18 times faster. The less extreme: BEGIN{while(++i<1000000) s="abc " i} is 30% faster. See GitHub issue #193.

vi: fixes to string search in colon commands, closes 10321

2020-01-29T13:01:50+00:00

Handling of string searches in colon commands (e.g ':/pat1/,/pat2/cmd') differ from standard vi: - As reported in bug 10321 such searches can't be repeated using the 'n' command. This is because the last search pattern isn't updated. - The search also can't be repeated using the command '://' because an empty search pattern doesn't imply the use of the last search pattern. - Such searches should start on the line after the current line, otherwise '://' never moves to the next occurrence of the pattern. This can also affect other cases where line ranges are specified using search patterns. Fix these various issues. function old new delta get_one_address 325 342 +17 Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
