580:
581: * OS/2 version looks for less.ini in $HOME before $INIT and $PATH.
582:
583: * Bug fixes
584:
585: ======================================================================
586:
587:
588: Major changes between "less" versions 252 and 278
589:
590: * A LESSOPEN preprocessor may now pipe the converted file data to less,
591: rather than writing it to a temporary file.
592:
593: * Search pattern highlighting has been fixed. It now highlights
594: reliably, even if a string is split across two screen lines,
595: contains TABs, etc.
596:
597: * The -F flag (which suppress search highlighting) has been changed
598: to -G. A new flag, -g, changes search highlighting to highlight
599: only the string found by the last search command, instead of all
600: strings which match the last search command.
601:
602: * New flag -I acts like -i, but ignores case even if the search
603: pattern contains uppercase letters.
604:
605: * Less now checks for the environment variable VISUAL before EDITOR.
606:
607: * Ported to OS/2.
608:
609: ======================================================================
610:
611:
612: Major changes between "less" versions 237 and 252
613:
614: * Changes in line-editing keys:
615: The literal key is now ^V or ^A rather than \ (backslash).
616: Filename completion commands (TAB and ^L) are disabled
617: when typing a search pattern.
618:
619: * Line-editing command keys can be redefined using lesskey.
620:
621: * Lesskey with no input file defaults to $HOME/.lesskey
622: rather than standard input.
623:
624: * New option -V displays version number of less.
625:
626: * New option -V displays version number of lesskey.
627:
628: * Help file less.hlp is now installed by default in /usr/local/share
629: rather than /usr/local/lib.
630:
631:
632: ======================================================================
633:
634:
635: Major changes between "less" versions 170 and 237
636:
637: * By popular demand, text which matches the current search pattern
638: is highlighted. New -F flag disables this feature.
639:
640: * Henry Spencer's regexp.c is now included, for systems which do not
641: have a regular expression library.
642: regexp.c is Copyright (c) 1986 by University of Toronto.
643:
644: * New line-editing keys, including command history (arrow keys) and
645: filename completion (TAB).
646:
647: * Input preprocessor allows modification of input files (e.g. uncompress)
648: via LESSOPEN/LESSCLOSE environment variables.
649:
650: * New -X flag disables sending termcap "ti" and "te" (initialize and
651: deinitialize) strings to the terminal.
652:
653: * Changing -i from within less now correctly affects a subsequent
654: repeated search.
655:
656: * Searching for underlined or overstruck text now works when the -u
657: flag is in effect, rather than the -i flag.
658:
659: * Use setlocale (LANG and LC_CTYPE environment variables) to determine
660: the character set if LESSCHARSET/LESSCHARDEF are not set.
661:
662: * The default format for displaying binary characters is now standout
663: (reverse video) rather than blinking. This can still be changed by
664: setting the LESSBINFMT environment variable.
665:
666: * Use autoconf installation technology.
667:
668: * Ported to MS-DOS.
669:
670: ********************************
671: Things that may surprise you
672: ********************************
673:
674: * When you enter text at the bottom of the screen (search string,
675: filename, etc.), some keys act different than previously.
676: Specifically, \ (backslash), ESC, TAB, BACKTAB, and control-L
677: now have line editing functions.
678:
679: * Some previous unofficial versions of less were able to display
680: compressed files. The new LESSOPEN/LESSCLOSE feature now provides
681: this functionality in a different way.
682:
683: * Some previous unofficial versions of less provided a -Z flag to
684: set the number of lines of text to retain between full screen scrolls.
685: The -z-n flag (that is, -z with a negative number) provides this
686: functionality.
687:
688:
689: ======================================================================
690:
691:
692: Major changes between "less" versions 123 and 170
693:
694: * New option -j allows target lines to be positioned anywhere on screen.
695:
696: * New option -S truncates displayed line at the screen width,
697: rather than wrapping onto the next line.
698:
699: * New option -y limits amount of forward scroll.
700:
701: * New option -T specifies a "tags" file.
702:

704: Such characters, as well as control characters, are displayed
705: in blinking mode.
706:
707: * New command -+ sets an option to its default.
708: * New command -- sets an option to the opposite of its default.
709:
710: * Lesskey file may have a string appended to a key's action,
711: which acts as though typed in after the command.
712:
713: * New commands ESC-^F and ESC-^B match arbitrary types of brackets.
714:
715: * New command F monitors a growing file (like "tail -f").
716:
717: * New command | pipes a section of the input file into a shell command.
718:
719: * New command :x directly jumps to a file in the command line list.
720:
721: * Search commands have been enhanced and reorganized:
722: n Repeat search, same direction.
723: N Repeat search, opposite direction.
724: ESC-/ Search forward thru file boundaries
725: ESC-? Search backward thru file boundaries
726: ESC-n Repeat search thru file boundaries, same direction.
727: ESC-N Repeat search thru file boundaries, opposite direction.
728: Special character * causes search to search thru file boundaries.
729: Special character @ causes search to begin at start/end of file list.
730:
731: * Examining a new file adds it to the command line list.
732: A list of files, or an expression which matches more than one file,
733: may be examined; all of them are added to the command line list.
734:
735: * Environment variables LESSCHARSET and LESSCHARDEF can define
736: a non-ASCII character set.
737:
738: * Partial support for MSDOS, including options -R for repainting screen
739: on quit, -v/-V to select video mode, and -W to change window size.
740:
741:
742: ======================================================================
743:
744:
745: Major changes between "less" versions 97 and 123
746:
747: * New option (-N) causes line numbers to be displayed in the
748: text of the file (like vi "set nu").
749:
750: * New option (-?) prints help message immediately.
751:
752: * New option (-r) displays "raw" control characters, without
753: mapping them to ^X notation.
754:
755: * New option (-f) forces less to open non-regular files
756: (directories, etc).
757:
758: * New option (-k) can be used to specify lesskey files by name.
759:
760: * New option (-y) can be used to set a forward scroll limit
761: (like -h sets a backward scroll limit).
762:
763: * File marks (set by the m command) are now preserved when a new
764: file is edited. The ' command can thus be used to switch files.
765:
766: * New command ESC-/ searches all files (on the command line)
767: for a pattern.
768:
769: * New command ESC-n repeats previous search, spanning files.
770:
771: * The N command has been changed to repeat the previous search
772: in the reverse direction. The old N command is still available
773: via :n.
774:
775: * New command ESC-N repeats previous search in the reverse
776: direction and spanning files.
777:
778: * 8 bit characters are now supported. A new option (-g) can be
779: used to strip off the eighth bit (the previous behavior).
780:
781: * Options which take a following string (like -t) may now
782: optionally have a space between the option letter and the string.
783:
784: * Six new commands { } ( ) [ and ] can be used to match
785: brackets of specific types, similar to vi % command.
786:
787: * New commands z and w move forward/backward one window and
788: simultaneously set the window size.
789:
790: * Prompt string expansion now has %L for line number of the last
791: line in the file, and %E for the name of the editor.
792: Also, % escapes which refer to a line (b=bottom, t=top, etc.)
793: can use j for the jump target line.
794:
795: * New environment variable LESSEDIT can be used to tailor the
796: command string passed to the editor by the v command.
797:
798: * Examining a file which was previously examined will return
799: to the same position in the file.
800:
801: * A "%" is expanded to the current filename and a "#" to the
802: previous filename, in both shell commands and the E command.
803: (Previously % worked only in shell commands and # worked
804: only in the E command.)
805:
806: * New command ":ta" is equivalent to "-t".
807:
808: * New command "s" is equivalent to "-l".

811: for option X, or "-X" to get the opposite of the default.
812:
813: * Lesskey files may now include characters after the action as
814: extra input to be parsed after the action; for example:
