Help text is now + embedded in the less executable itself. + +* Added -Ph to change the prompt for the help text. + Added -Ps to change the default short prompt (same as plain -P). + +* Ported to the Borland C compiler for MS-DOS. + +* Ported to Windows 95 & Windows NT. + +* Ported to OS-9. + +* Ported to GNU Hurd. + +====================================================================== + + + Major changes between "less" versions 290 and 291 + +* Less environment variables can be specified in lesskey files. + +* Fixed MS-DOS build. + +====================================================================== + + + Major changes between "less" versions 278 and 290 + +* Accepts GNU-style options "--help" and "--version". + +* OS/2 version looks for less.ini in $HOME before $INIT and $PATH. + +* Bug fixes + +====================================================================== + + + Major changes between "less" versions 252 and 278 + +* A LESSOPEN preprocessor may now pipe the converted file data to less, + rather than writing it to a temporary file. + +* Search pattern highlighting has been fixed. It now highlights + reliably, even if a string is split across two screen lines, + contains TABs, etc. + +* The -F flag (which suppress search highlighting) has been changed + to -G. A new flag, -g, changes search highlighting to highlight + only the string found by the last search command, instead of all + strings which match the last search command. + +* New flag -I acts like -i, but ignores case even if the search + pattern contains uppercase letters. + +* Less now checks for the environment variable VISUAL before EDITOR. + +* Ported to OS/2. + +====================================================================== + + + Major changes between "less" versions 237 and 252 + +* Changes in line-editing keys: + The literal key is now ^V or ^A rather than \ (backslash). + Filename completion commands (TAB and ^L) are disabled + when typing a search pattern. + +* Line-editing command keys can be redefined using lesskey. + +* Lesskey with no input file defaults to $HOME/.lesskey + rather than standard input. + +* New option -V displays version number of less. + +* New option -V displays version number of lesskey. + +* Help file less.hlp is now installed by default in /usr/local/share + rather than /usr/local/lib. + + +====================================================================== + + + Major changes between "less" versions 170 and 237 + +* By popular demand, text which matches the current search pattern + is highlighted. New -F flag disables this feature. + +* Henry Spencer's regexp.c is now included, for systems which do not + have a regular expression library. + regexp.c is Copyright (c) 1986 by University of Toronto. + +* New line-editing keys, including command history (arrow keys) and + filename completion (TAB). + +* Input preprocessor allows modification of input files (e.g. uncompress) + via LESSOPEN/LESSCLOSE environment variables. + +* New -X flag disables sending termcap "ti" and "te" (initialize and + deinitialize) strings to the terminal. + +* Changing -i from within less now correctly affects a subsequent + repeated search. + +* Searching for underlined or overstruck text now works when the -u + flag is in effect, rather than the -i flag. + +* Use setlocale (LANG and LC_CTYPE environment variables) to determine + the character set if LESSCHARSET/LESSCHARDEF are not set. + +* The default format for displaying binary characters is now standout + (reverse video) rather than blinking. This can still be changed by + setting the LESSBINFMT environment variable. + +* Use autoconf installation technology. + +* Ported to MS-DOS. + + ******************************** + Things that may surprise you + ******************************** + +* When you enter text at the bottom of the screen (search string, + filename, etc.), some keys act different than previously. + Specifically, \ (backslash), ESC, TAB, BACKTAB, and control-L + now have line editing functions. + +* Some previous unofficial versions of less were able to display + compressed files. The new LESSOPEN/LESSCLOSE feature now provides + this functionality in a different way. + +* Some previous unofficial versions of less provided a -Z flag to + set the number of lines of text to retain between full screen scrolls. + The -z-n flag (that is, -z with a negative number) provides this + functionality. + + +====================================================================== + + + Major changes between "less" versions 123 and 170 + +* New option -j allows target lines to be positioned anywhere on screen. + +* New option -S truncates displayed line at the screen width, + rather than wrapping onto the next line. + +* New option -y limits amount of forward scroll. + +* New option -T specifies a "tags" file. + +* Non-printable, non-control characters are displayed in octal. + Such characters, as well as control characters, are displayed + in blinking mode. + +* New command -+ sets an option to its default. +* New command -- sets an option to the opposite of its default. + +* Lesskey file may have a string appended to a key's action, + which acts as though typed in after the command. + +* New commands ESC-^F and ESC-^B match arbitrary types of brackets. + +* New command F monitors a growing file (like "tail -f"). + +* New command | pipes a section of the input file into a shell command. + +* New command :x directly jumps to a file in the command line list. + +* Search commands have been enhanced and reorganized: + n Repeat search, same direction. + N Repeat search, opposite direction. + ESC-/ Search forward thru file boundaries + ESC-? Search backward thru file boundaries + ESC-n Repeat search thru file boundaries, same direction. + ESC-N Repeat search thru file boundaries, opposite direction. + Special character * causes search to search thru file boundaries. + Special character @ causes search to begin at start/end of file list. + +* Examining a new file adds it to the command line list. + A list of files, or an expression which matches more than one file, + may be examined; all of them are added to the command line list. + +* Environment variables LESSCHARSET and LESSCHARDEF can define + a non-ASCII character set. + +* Partial support for MSDOS, including options -R for repainting screen + on quit, -v/-V to select video mode, and -W to change window size. + + +====================================================================== + + + Major changes between "less" versions 97 and 123 + +* New option (-N) causes line numbers to be displayed in the + text of the file (like vi "set nu"). + +* New option (-?) prints help message immediately. + +* New option (-r) displays "raw" control characters, without + mapping them to ^X notation. + +* New option (-f) forces less to open non-regular files + (directories, etc). + +* New option (-k) can be used to specify lesskey files by name. + +* New option (-y) can be used to set a forward scroll limit + (like -h sets a backward scroll limit). + +* File marks (set by the m command) are now preserved when a new + file is edited. The ' command can thus be used to switch files. + +* New command ESC-/ searches all files (on the command line) + for a pattern. + +* New command ESC-n repeats previous search, spanning files. + +* The N command has been changed to repeat the previous search + in the reverse direction. The old N command is still available + via :n. + +* New command ESC-N repeats previous search in the reverse + direction and spanning files. + +* 8 bit characters are now supported. A new option (-g) can be + used to strip off the eighth bit (the previous behavior). + +* Options which take a following string (like -t) may now + optionally have a space between the option letter and the string. + +* Six new commands { } ( ) [ and ] can be used to match + brackets of specific types, similar to vi % command. + +* New commands z and w move forward/backward one window and + simultaneously set the window size. + +* Prompt string expansion now has %L for line number of the last + line in the file, and %E for the name of the editor. + Also, % escapes which refer to a line (b=bottom, t=top, etc.) + can use j for the jump target line. + +* New environment variable LESSEDIT can be used to tailor the + command string passed to the editor by the v command. + +* Examining a file which was previously examined will return + to the same position in the file. + +* A "%" is expanded to the current filename and a "#" to the + previous filename, in both shell commands and the E command. + (Previously % worked only in shell commands and # worked + only in the E command.) + +* New command ":ta" is equivalent to "-t". + +* New command "s" is equivalent to "-l". + +* The - command may be followed by "+X" to revert to the default + for option X, or "-X" to get the opposite of the default. + +* Lesskey files may now include characters after the action as + extra input to be parsed after the action; for example: + "toggle-option X" to toggle a specific option X. |
