the_silver_searcher

工具介绍

类似Ack的代码搜索工具,但更快.

核心特点

• •It is an order of magnitude faster than ack.
• •It ignores file patterns from your .gitignore and .hgignore.
• •If there are files in your source repo you don't want to search, just add their patterns to a .ignore file. (\*cough\* *.min.js \*cough\*)
• •The command name is 33% shorter than ack, and all keys are on the home row!
• •Ag uses Pthreads to take advantage of multiple CPU cores and search files in parallel.
• •Files are mmap()ed instead of read into a buffer.
• •Literal string searching uses Boyer-Moore strstr.
• •Regex searching uses PCRE's JIT compiler (if Ag is built with PCRE >=8.21).
• •Ag calls pcre_study() before executing the same regex on every file.
• •Instead of calling fnmatch() on every pattern in your ignore files, non-regex patterns are loaded into arrays and binary searched.
