v0.2.0

Added

• -o as shorthand for -t o, matching GNU strings. (#51)
• -e L and -e B for 32-bit little- and big-endian characters, matching GNU
  strings. (#52)
• -d/--data to scan only the data sections of a thin Mach-O file, and
  -a/--all to scan the whole file (still the default), matching GNU
  strings. (#54)
• -d also scans the data sections of ELF files, 32- and 64-bit in either byte
  order. (#57)

Changed

• Scanning with -e s and -e S is roughly 1.75x and 2x faster. (#50)
• Input files are memory-mapped and scanned one at a time, so memory use no longer grows with file size or file count. (#53)
• Filenames are printed only with -f, matching GNU strings. Output for multiple files without -f no longer includes filenames; add -f to get the old output. With -f, stdin is now labelled {standard input}, as in GNU, rather than <stdin>. (#63)

Fixed

• Exits 1 quietly, rather than printing "Exception ignored" and exiting 120, when the output pipe closes before buffered output is flushed. (#58)
• Tab no longer ends a string, and -w now also includes vertical tab and form feed, matching GNU strings. This changes default output for any string containing a tab. (#59)
• -e S writes bytes 0x80-0xFF as the raw bytes found, as GNU strings does, rather than UTF-8-encoding them. (#61)
• -e l, -e b, -e L and -e B find strings at any byte offset, not only at multiples of the character width, matching GNU strings; they also scan 3-7x faster. (#65)

v0.1.0

Added

• Initial release. Extracts printable character sequences from binary files,
  reimplementing the Unix strings utility in pure Python with no runtime
  dependencies.
• Four encodings via -e: 7-bit ASCII (s, the default), 8-bit extended
  ASCII (S), and UTF-16 little- and big-endian (l and b).
• -n to set the minimum string length, -t to print byte offsets in
  decimal, octal or hexadecimal, -w to treat all whitespace as part of a
  string, and -f to print the filename before each match.
• Reads from stdin when given no file arguments or a - argument, and accepts
  multiple files in one invocation.
• Exits quietly when the output pipe closes early, so sillystrings big.bin | head behaves like coreutils rather than printing a BrokenPipeError.
