These include how I added pthreads, wrote my own scandir(), benchmarked every revision to find performance regressions, and profiled with gprof and Valgrind. I've written several blog posts showing how I've improved performance. Instead of calling fnmatch() on every pattern in your ignore files, non-regex patterns are loaded into arrays and binary searched.Ag calls pcre_study() before executing the same regex on every file.Regex searching uses PCRE's JIT compiler (if Ag is built with PCRE >=8.21).Literal string searching uses Boyer-Moore strstr.Files are mmap()ed instead of read into a buffer.Ag uses Pthreads to take advantage of multiple CPU cores and search files in parallel.There are also graphs of performance across releases. Thanks to git/hg/ignore, Ag only searched 700MB of that. It's much faster than Ack in my benchmarks: ack test_blah ~/code/ 104.66s user 4.82s system 99% cpu 1:50.03 totalĪg test_blah ~/code/ 4.67s user 4.58s system 286% cpu 3.227 totalĪck and Ag found the same results, but Ag was 34x faster (3.2 seconds vs 110 seconds). Most changes are new features, minor bug fixes, or performance improvements. The command name is 33% shorter than ack, and all keys are on the home row!Īg is quite stable now.If there are files in your source repo you don't want to search, just add their patterns to a.It is an order of magnitude faster than ack.
#MSYS2 RIPGREP CODE#
A code searching tool similar to ack, with a focus on speed.ĭo you know C? Want to improve ag? I invite you to pair with me.
