New in ugrep 4.3.0 (Oct 8, 2023)

  • Redesigned TUI with a new split screen window pane to preview matching files.
  • new TUI split screen, activated with CTRL-T, and new option --split to start the TUI with a split screen (add split to your .ugrep configuration file to enable) #254

  • fixed compressed file search of files that are exactly one byte long, instead of rejecting those files as being empty
  • updated performance benchmark results: ugrep is faster than other grep tools on x64 and arm64 machines in nearly every test of 564 benchmark test cases

New in ugrep 4.2.0 (Sep 22, 2023)

  • Improved TUI to display search progress and final stats in a status line at the bottom
  • Improved TUI ctrl-Y to jump to the corresponding line number in the pager #296
  • Improved recursive search performance #297
  • Improved compatibility with GNU grep #273
  • Improved detection of special devices to avoid searching them

New in ugrep 4.1.0 (Sep 17, 2023)

  • Fix -Z fuzzy matching when character deletions are solely specified with a minus sign, as in -Z-NUM e.g. with -Z-1 the pattern 'abcd' should still match 'acd' with a missing character 'b' in the input (-Z worked fine, but -Z-1 did not match)
  • Fix --pager when a regex syntax error occurs #285
  • Update --pager to use $PAGER #286
  • Update --ignore-files for compliance with git and ag gitignore rules #118
  • Update -Q TUI ctrl-S and ctrl-W to jump to context group separators when context options -ABC are specified
  • Update -o for GNU grep compatibility with "empty-matching" patterns

No regex pattern matches newlines, except for n, R and X, P{C} (anything not in Unicode class C), D (anything not a digit), H (anything not blank), and W (anything not a word character), for the latter patterns you can/should use the more conventional character classes [^p{C}], [^d] [^h] and [^w], respectively, to not match newlines
  • Improve performance: faster -c and line matching #284
  • Improve performance: faster "empty-matching" pattern search #287

  • updated --save-config as per user request
  • correct an issue with -o and context

New in ugrep 4.0.3 (Aug 25, 2023)

  • faster async output, speeds up ugrep 3x when outputting many matching lines
  • removed "rest line" buffering, speeds up ugrep up to 2x, depending on the output-related options used
  • removed redundant "binary file" checking, speeds up ugrep 10%~20%
  • double size input buffer, speeds up searching 5%~20% when searching very large files (GB) with none/infrequent pattern matches
  • faster empty pattern matching, i.e. pattern '' matches all lines faster, as much as 10x faster
  • removed redundant color escape codes from the output
  • option -Q with an optional argument is now -Q=DELAY instead of -QDELAY, so -Q2 is -Q -2 (simple options should be composable/separable) which searches 2 directory levels deep with the query TUI
  • fully tested --index (still beta version) to search indexed file systems, see also WIP project ugrep-indexer

New in ugrep 3.12.7 (Aug 14, 2023)

  • This update of ugrep includes a compatibility improvement with one of GNU grep's idiosyncrasies: unpaired ) in regex are matched literally. This behavior is automatically in effect when the grep and egrep aliases of ugrep are used or explicitly with option -Y.

New in ugrep 3.12.6 (Aug 6, 2023)

  • New option -S (--dereference-files) to follow symbolic lines only to files, not to directories, when using option -r for recursive search. Updated default recursive search to strictly perform -r without following any symbolic links. New option --index for fast index-based search with the new ugrep-indexer tool. The ugrep-indexer tool is released on GitHub as a separate open source project.

New in ugrep 3.12.5 (Aug 4, 2023)

  • New --iglob and --glob-ignore-case options, as requested by ugrep users.

New in ugrep 3.12.3 (Jul 15, 2023)

New in ugrep 3.12.2 (Jul 9, 2023)

  • Speed improvements to further speed up common search patterns. Improved man page. The ug and ug+ commands now enable --pretty by default (that is, if a .ugrep configuration file does not override it with no-pretty).

New in ugrep 3.12.1 (Jun 5, 2023)

  • New ug+ and ugrep+ commands to search pdfs, documents and image metadata when the corresponding tools are installed, includes a runtime check for tool availability; improved --filter option; speed improvements.
  • Ugrep runs faster than grep and ripgrep on Apple Silicon M1 and x64 machines for most common searches, such as searching for a few words to tens and hundreds of words in large files. It depends on the available hardware and the complexity of the search patterns.
  • Experiments on a MacBook PRO M1. The average elapsed time of 100 test runs of ugrep, ripgrep and GNU grep with increasing number of randomly picked words from the enwik8 100MB benchmark file
  • Results are for ugrep -on -f words enwik8 to search with line numbers and option -o to reduce output overhead. The performance of ugrep and ripgrep are more or less comparable when searching more strings and when searching more complex regex patterns. It depends.

New in ugrep 3.12.0 (Jun 3, 2023)

  • New ug+ and ugrep+ commands to search pdfs, documents and image metadata when the corresponding tools are installed;
  • Improved --filter option;
  • Seed improvements.

New in ugrep 3.11.2 (Apr 8, 2023)

  • This update includes usability improvements. We improved option --hyperlink to optionally take parameters PREFIX and +. The PREFIX parameter replaces file:// in the link with a custom PREFIX://. The + included the line number in the link, and when ugrep option -k is used, also includes the column number in the link.

New in ugrep 3.11.1 (Apr 2, 2023)

  • Smarter interactive navigation in the TUI when option --tree is used with option -l or -c, enabling the navigation keys CTRL-S (jump forward), CTRL-W jump backward), TAB (chdir into directory and save query state), SHIFT-TAB (chdir .. and restore query state), CTRL-Y (view file).

New in ugrep 3.11.0 (Mar 19, 2023)

  • New --replace option to replace pattern matches with custom formatted text in the output with % format fields. This option can be combined with any other option, including -y (--any-line) to pass through a file with substitutions applied to the output. To make ugrep more user-friendly, the new --help format option argument displays a summary of % format fields, the new --help regex option argument displays an overview of regular expression pattern syntax, and the new --help globs option argument displays the gitignore-style glob syntax and conventions used by ugrep. Increased searching speed of large files with AVX optimizations applied to the default pattern matcher engine. AVX optimizations were largely disabled (only partially applied) to make ugrep binary portable on Linux platforms since ugrep v3.3.5, requested by issue trackers #103 and #143. Binary portability over x86/x64 now works better with new multi-version code selected at runtime to run the original faster pattern matching engine. More coming soon!

New in ugrep 3.5.0 (Jan 5, 2022)

  • New --zmax=NUM option to be used with -z (--decompress) to search compressed files and archives recursively stored within tar/zip/cpio/pax archives, e.g. to search tar and zip files stored in (compressed) tar files, in zip files etc. for up to NUM recursive levels deep. The --zmax argument may range from 1 (default) to 99 for up to 99 decompression and de-archiving steps. Improved option -U to be used for backward compatibility with GNU/BSD grep by no longer flagging invalid UTF as "binary files". More to come soon!

New in ugrep 3.4.0 (Dec 20, 2021)

  • New Boolean search query options --files and --lines. The specified Boolean search query conditions apply to lines by default. Because GNU/BSD grep and ugrep are generally line-based, --lines is the default option. Specify --files --bool to apply the specified Boolean query to files as a whole: a file matches if all Boolean conditions are satisfied by matching patterns anywhere in the file. More to come soon!

New in ugrep 3.3.12 (Dec 11, 2021)
