比 ack 更快,而且还可以跟 vim,textmate,emacs 集成,推荐之。 https://github.com/ggreer/the_silver_searcher
An attempt to make something better than ack
(which itself is better than grep
).
ack
..gitignore
and .hgignore
..agignore
file. *cough* extern *cough*ack
!mmap()
ed instead of read into a buffer.pcre_study()
before executing the regex on a jillion files.fnmatch()
on every pattern in your ignore files, non-regex patterns are loaded into an array and binary searched.I've written several blog posts showing how I've improved performance. These include how I added pthreads, wrote my own scandir()
, benchmarked every revision to find performance regressions, and profiled with gprof and Valgrind.
