PeculiarLog is a lightweight log filtering tool supporting regular expressions and instant (as-you-type) results.
It is designed to work with huge multi-gigabyte text files utilizing the power of Intel Hyperscan engine running on multiple CPU cores.
You can find most recent compiled version here
Since PeculiarLog is based on Intel Hyperscan engine it is expecting headers to be available at
/usr/local/opt/hyperscan/include/hs and libhs.a located at
Brew is the easiest way to install Hyperscan engine.
$ brew install hyperscan
When everything is set, open Xcode project to build PeculiarLog from source. Minimum requirements - Xcode 9 and Swift 4.1.
In order to make it even faster on host with AVX512 instructions it is necessary to rebuild HyperScan with the following options.
$ mkdir build $ cd build $ cmake -DBUILD_AVX512=on -DCMAKE_BUILD_TYPE=Release -DBUILD_STATIC_AND_SHARED=on ../ $ make
Then link new
libhs.a to the project or replace the one installed with Brew.
Just open app, drag log file to the icon and start typing regex in the field. Use setting panel or shortcuts to change scope, toggle caseless regex or line numbers.
There are several limitation applied to the supported regex patterns by Hyperscan.
Hyperscan supports the pattern syntax used by the PCRE library (“libpcre”), described at <http://www.pcre.org/>. However, not all constructs available in libpcre are supported. The use of unsupported constructs will result in compilation errors. The version of PCRE used to validate Hyperscan’s interpretation of this syntax is 8.41 or above.
⇧ ⌃ ↑ - increase 'before' scope ⇧ ⌃ ↓ - decrease 'before' scope ⇧ ⌘ ↑ - decrease 'after' scope ⇧ ⌘ ↓ - increase 'after' scope ⇧ ⌘ c - toggle caseless regex ⇧ ⌘ l - toggle line numbers
There is also a hint on the right side of a settings panel.
