ugrep v7.1.1

What's new?

• fix negative character classes when option -i or --ignore-case is used and make ugrep closely emulate GNU grep's character class behavior when options -i and -P are used #445
• appease -Woverload-virtual and -Wshadow warnings when building the RE/flex library, the TUI, and indexer (some warnings remain in ugrep.cpp) #444

ugrep v7.1

What's new?

• add syntax highlighting to the TUI glob editor #443 and other TUI improvements
• add support for option --filter to Windows ug.exe and ugrep.exe #442
• make the ug+ and ugrep+ scripts work if no helper is available #440

ugrep v7.0.4

What's new?

• fix Windows ugrep.exe TUI issue #438 after TUI usability improvements #435, #436 and #437, which caused some users to struggle with TUI usability issues due to Windows API peculiarities with different Windows OS and different terminal apps

ugrep v7.0.3

What's new?

• make Windows ugrep.exe TUI cursor keys behave with ConEmu #435
• fix Windows ugrep.exe TUI CTRL-Y file viewing for non-ASCII filenames #436
• minor usability improvements suggested by ugrep users. Thank you for your feedback!

ugrep v7.0.2

Fix #434 ugrep v7 regression bug: an issue with the regex ^ anchor due to a misaligned begin-of-line position in the buffer after the buffer shifts on large input files. As a result, the -v option did not always work properly on large input files when searching with regex ^ anchors. Reverted to the old logic. Included a minor change to handle hex context lines #428. All extensively tested.

ugrep v7.0

What's new?

• rewritten SIMD acceleration logic and the search algorithm selection decision logic to speed up pattern matching (the actual speedup depends on the type of regex patterns specified) #432
• improved regex anchors and word boundary matching speed and support #426 and #427
• fix option --xml pathnames with special characters, which are unlikely to occur in pathnames, but aren't strictly forbidden #430
• updated option --hexdump with -ABC context hex lines before and after a match #428
• the TUI now also uses the VISUAL environment variable if PAGER is not set

ugrep v6.5

What's new?

• faster binary file checking with SIMD (SSE2/AVX2/NEON) UTF-8 validation #421 and benchmarks
• new option --context-separator=SEP
• options -W and -X now also apply to --format fields %o and %O to output hex
• ugrep-indexer option -z (indexes compressed files and zip/7z/tar/cpio/pax archives) no longer indexes hidden directories and files (i.e. "dotfiles") stored in archives, to save space
• fix ugrep-indexer option -z, which was broken due to a code refactoring mistake in a single line of code

ugrep v6.4.1

Fix #417

ugrep v6.4

What's new?

• new custom output format fields for options --format and --replace #414:

  %A          byte range in hex of match
  %l          last line number of match
  %L          number of lines of a match
  %R          newline, if --break
  %[hhhh]U    U+hhhh Unicode code point
  %y          matching pattern as hex
  %Y          matching line as hex
  %[ms]=...%= color of ms ... color off
  %[n]j       nth capture as JSON
  %[n]q       nth capture quoted
  %[n]x       nth capture as XML
  %[n]y       nth capture as hex
  %[n]v       nth capture as CSV
  %[name]j    named capture as JSON
  %[name]q    named capture quoted
  %[name]x    named capture as XML
  %[name]y    named capture as hex
  %[name]v    named capture as CSV
  %[n|...]j   capture n,... as JSON
  %[n|...]q   capture n,... quoted
  %[n|...]x   capture n,... as XML
  %[n|...]y   capture n,... as hex
  %[n|...]v   capture n,... as CSV
  

  • numeric fields such as %n are padded with spaces when %{width}n is specified with a numeric width > 0
  • matching line fields such as %O are cut to width when %{width}O is specified or when %{-width}O is specified to cut from the end of the line
  • character context on a matching line before or after a match is output when %{-width}o or %{+width}o is specified for match fields such as %o, where %{width}o without a +/- sign cuts the match to the specified width
• fix bash completions for key bindings #415

ugrep v6.3

What's new?

• option --index always enables --recursive #410
• new bash, fish and zsh ugrep-indexer completions #411
• option --hyperlink outputs absolute search paths #412
• update regex DFA cut optimization that was too agressive for some patterns
• option -o (--only-matching) with -ABC context now also supports multi-line pattern matching with \n (newline) in regex patterns

Note: again extensively tested with random (fuzzed) patterns to verify the match algorithms and optimizations.
