Makefile.aut	Delete emoji modifier characters from output. This is visually nicer than displaying them as hex codepoints as was done in c1e2880cecfcc5a10f39321df97dc9e8fac67ac6 and a69d8e4639dd8e7d27bf3d0eb5f98d98dd1fc662. The -U option can be used to get the hex codepoint display. LESSUTFCHARDEF can be used to set the modifiers to be composing rather than deleted, which is even better if the terminal supports the characters. However, this is not fully tested, since I have not found any terminal that fully supports all modifiers correctly. Related to #637.	9 个月前

Makefile.dsg	dos: fix djgpp build Only DJGPP build was tested, but these changes should help other dos build envs too. There were two issues: - undefined vt_enabled at win_flush() at output.c . - Write to read-only memory ("text") at WIN32textout() at screen.c . And, the DJGPP Makefile.dsg explicitly invokes command.com /c copy ... so try also cmd.exe and (nix) cp, so that it can also cross-compile. Note that command.com is also used explicitly at the make targets clean, distclean, realclean, and it remains unmodified, so those will not work when cross compiling on Windows or nix, but one can always clean the build manually. Also, Makefile.dsg doesn't generate funcs.h and help.c, so they should exist (e.g. a release tarball) or using e.g. Makefile.{aut\|wng}. The build was surprisingly smooth, without even a single warning. Interestingly, after stripping, it's nearly twice as big compared to a windows 32 bit build (400k in DJGPP, about 200k windows binary). Tested in dosbox after (cross) compiling with DJGPP, and with the DJGPP DPMI loader CWSDPMI.EXE at the same dir, and, alternatively, with the DPMI loader embedded to create a standalone less.exe: EXE2COFF less.exe # creates "less" coff image. COPY /B CWSDSTUB.EXE+less less.exe # cat CWSDSTUB.EXE less >less.exe Colors/SGR (at the help page, and with -R) seem to work fine too. UTF-8 displays broken by default, which I guess is expected. Used DJGPP tools (gcc 12.2): https://github.com/andrewwutw/build-djgpp	2 年前

Makefile.wng	Windows: mingw: Makefile.wng: allow native funcs.h, help.c We already have buildgen.c which can be used to generate funcs.h and help.c without grep/sed/perl/sh/etc, which can be useful in mingw setups on Windows which don't bring the whole posix arsenal with them. The default is still the posix tools, but now adding WINGEN=1 will use buildgen.c instead of the posix tools. The compiler which is used with buildgen.c is the same compiler used at the rest of Makefile.wng, so it should be native (not cross build).	2 年前
Makefile.wnm	windows: msvc: Makefile.wnm: allow generating funcs.h, help.c Previously the mscv Makefile.wnm didn't have rules to generate funcs.h and help.c, meaning that it could only be used to build release tarballs (which already have these files), but not git snapshots. Now we have a new independent rule "generated" (not part of "all"), which generates them. Because typical msvc setups do't have the tools which are used elsewhere to generate these files, this commit adds buildgen.c which, when compiled, can be used instead. It's not part of "all" because when cross compiling, e.g. an arm binary on Windows 64, buildgen.exe should be native and not arm, so this allows making "generated" with a native toolchain, and then "all" using the arm toolchain.	2 年前

lesskey.nro.VER	man pages: Fix unescaped hyphens. groff_man_style(7): Several special characters are also widely portable. Except for \-, \[em], and \[ga], AT&T troff did not consistently define the characters listed below, but its descendants, like DWB, Plan 9, or Solaris 10 troff, can be made to support them by defining them in font description files, making them aliases of existing glyphs if necessary; see groff_font(5). groff’s extended notation for special characters, \[xx], is also supported by mandoc(1), Heirloom Doctools troff, and neatroff, but not DWB, Plan 9, or Solaris 10 troffs. \- Minus sign. \- produces the basic Latin hyphen‐minus (U+002D) specifying Unix command‐line options and frequently used in file names. “-” is a hyphen in roff; some output devices format it as U+2010 (hyphen). With groff man(7), because \- is not a hyphenation break point, this change also prevents less's long option names from breaking across lines, which makes copy-and-paste from the man page more convenient.

lglob.h	build: Make mingw build work properly from autotools This change makes a mingw build work from the standard autotools ./configure workflow. There are two mostly independent changes: 1. Change the mingw detection preprocessor macro to the standard __MINGW32__ which is defined by the compiler (rather than expecting MINGW to be set by the defines header). 2. In the autotools-emitted defines.h make the values of MSDOS_COMPILER and PATHNAME_SEP appropriately automatically. I understand that there already is a spearate Makefile for mingw. However, it would be convenient to make the autotools version just work as well. In paprticular, I'm working on packaging less for https://github.com/JuliaPackaging/Yggdrasil. The system sets various defaults when it detects an autotools build. Of course, it would be possible to manually apply these for a mingw build, but it would be easier if the autotools build just worked.	10 个月前
line.c	Rename ignaw to defer_wrap. xn can officially mean two things, and there's no way to tell whether the terminal behaves like one or the other: The first interpretation, by almost all terminals, including VT100, means the cursor stays at the last column after printing one printable char at the last column, and only wraps to the next line (and possibly scrolls) when an additional printable char is printed (e.g. printing a printable char to the last column and then printing SGR sequences doesn't wrap). The second interpretation (no terminal which I know of behaves like this), means "if newline is printed right after it wrapped (and possibly scrolled), then ignore this newline". Less uses the first interpretation, so rename the variable to something more consistent with that interpretation.	6 个月前

Also implement ctl-HOME and shift-HOME to be like g-ESC-{ (go to beginning of file and beginning of line) and implement ctl-END and shift-END to be like G-ESC-} (go to end of file and end of line). The ctl- versions depend on the terminfo entry for the terminal containing the nonstandard kHOM5 and kEND5 caps. Related to #658.	7 个月前

mkhelp.sh	windows: mingw: Makefile.wng: use mkhelp.sh if perl is missing On Windows perl can be installed, but it's a non-trivial dependency. If perl is missing to process less.hlp, then try also the newly added mkhelp.sh script (which uses od and awk in standard POSIX syntax). The makefile already assumes grep and sed (for funcs.h), and it's highly likely that sh, od, and awk are available as well. The minimum requirements are now a mingw compiler, gnu make, sh or cmd.exe, and gnu coreutils or busybox[-w32] - on *nix or Windows.	2 年前
mkinstalldirs	Reconstruct version 394. Versions between 382 and 394 are lost.	19 年前
mkutable	Delete emoji modifier characters from output. This is visually nicer than displaying them as hex codepoints as was done in c1e2880cecfcc5a10f39321df97dc9e8fac67ac6 and a69d8e4639dd8e7d27bf3d0eb5f98d98dd1fc662. The -U option can be used to get the hex codepoint display. LESSUTFCHARDEF can be used to set the modifiers to be composing rather than deleted, which is even better if the terminal supports the characters. However, this is not fully tested, since I have not found any terminal that fully supports all modifiers correctly. Related to #637.	9 个月前

pattern.c	Fix hang with ^S modifier if search matches empty string. b71a5788d added a loop in match_pattern that iterates through matches in a line looking for one that also satisfies any SUBSEARCH requirement in effect (via the ^S modifier). It starts each search at the end of the string matched by the previous search. But if a search matches an empty string, this will get stuck in the loop, continually searching from the same point.

Please report any problems at https://github.com/gwsw/less/issues.
See https://greenwoodsoftware.com/less for the latest info.
Source repository is at https://github.com/gwsw/less.git.

=========================================================================

You should build from a clone of a git repository ONLY IF you are doing development on the less source itself. If you are merely using less as a tool, you should download a release from https://greenwoodsoftware.com and NOT from github.

The formatted manual page is in less.man. The manual page nroff source is in less.nro. Major changes made since the last posted version are in NEWS.

======================================================================= INSTALLATION (Unix & Linux systems only):

Move the distributed source to its own directory and unpack it, if you have not already done so.
If you are building from a clone of a git repository, type "make -f Makefile.aut distfiles". If you are building from a numbered release package (a tar or zip file with a name like less-999.tar.gz or less-999.zip downloaded from greenwoodsoftware.com, not from github), you should skip this step.
Type "sh configure". This will generate a Makefile and a defines.h. Warning: if you have a GNU sed, make sure it is version 2.05 or later.

The file INSTALL describes the usage of the configure program in general. In addition, these options to configure are supported:

--with-editor=program Specifies the default editor program used by the "v" command. The default is "vi".

--with-regex=lib Specifies the regular expression library used by less for pattern matching. The default is "auto", which means the configure program finds a regular expression library automatically. Other values are: gnu Use the GNU regex library. pcre Use the PCRE library. pcre2 Use the PCRE2 library. posix Use the POSIX-compatible regcomp. regcmp Use the regcmp library. re_comp Use the re_comp library. regcomp Use the V8-compatible regcomp. regcomp-local Use Henry Spencer's V8-compatible regcomp (source is supplied with less). none No regular expressions, only simple string matching.

--with-secure Builds a "secure" version of less, with some features disabled to prevent users from viewing other files, accessing shell commands, etc.
It is a good idea to look over the generated Makefile and defines.h and make sure they look ok. If you know of any peculiarities of your system that configure might not have detected, you may fix the Makefile now. Take particular notice of the list of "terminal" libraries in the LIBS definition in the Makefile; these may need to be edited. The terminal libraries will be some subset of -lncurses -lcurses -ltermcap -ltermlib

If you wish, you may edit defines.h to remove some optional features. If you choose not to include some features in your version, you may wish to edit the manual page "less.nro" and the help page "less.hlp" to remove the descriptions of the features which you are removing. If you edit less.hlp, you should run "make -f Makefile.aut help.c".
Type "make" and watch the fun.
If the make succeeds, it will generate the programs "less", "lesskey" and "lessecho" in your current directory. Test the generated programs.
When satisfied that it works, if you wish to install it in a public place, type "make install".

The default install destinations are: Executables (less, lesskey, lessecho) in /usr/local/bin Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 If you want to install any of these files elsewhere, define bindir and/or mandir to the appropriate directories.

Note to hackers: comments noting possible improvements are enclosed in double curly brackets {{ like this }}.

(Note that the above note was originally written at a time when "hackers" most commonly meant "enthusiastic and dedicated computer programmers", not "persons who attempt to circumvent computer security".)

======================================================================= INSTALLATION (MS-DOS systems only, with Microsoft C, Borland C, or DJGPP)

Move the distributed source to its own directory. Depending on your compiler, you may need to convert the source to have CR-LF rather than LF as line terminators.
If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
Look at MAKEFILE to make sure that the definitions for CC and LIBDIR are correct. CC should be the name of your C compiler and LIBDIR should be the directory where the C libraries reside (for Microsoft C only). If these definitions need to be changed, you can either modify the definitions directly in MAKEFILE, or set your environment variables CC and/or LIBDIR to override the definitions in MAKEFILE.
If you wish, you may edit DEFINES.DS to remove some optional features. If you choose not to include some features in your version, you may wish to edit the manual page LESS.MAN and the help page HELP.C to remove the descriptions of the features which you are removing.
Run your "make" program and watch the fun. If your "make" requires a flag to import environment variables, you should use that flag. If your compiler runs out of memory, try running "make -n >cmds.bat" and then run cmds.bat.
If the make succeeds, it will generate the programs "LESS.EXE" and "LESSKEY.EXE" in your current directory. Test the generated programs.
When satisfied that it works, you may wish to install LESS.EXE and LESSKEY.EXE in a directory which is included in your PATH.

======================================================================= INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, with Borland C or Microsoft Visual C++)

Move the distributed source to its own directory.
If you are using Borland C, rename Makefile.wnb to Makefile. If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
Check the Makefile to make sure the definitions look ok.
If you wish, you may edit defines.wn to remove some optional features. If you choose not to include some features in your version, you may wish to edit the manual page less.man and the help page help.c to remove the descriptions of the features which you are removing.
Type "make" and watch the fun.
If the make succeeds, it will generate the programs "less.exe" and "lesskey.exe" in your current directory. Test the generated programs.
When satisfied that it works, if you wish to install it in a public place, type "make install". See step 6 of the Unix installation instructions for details on how to change the default installation directories.

======================================================================= INSTALLATION (OS/2 systems only, with EMX C)

Move the distributed source to its own directory.
Rename Makefile.o2e to Makefile.
Check the Makefile to make sure the definitions look ok.
If you wish, you may edit defines.o2 to remove some optional features. If you choose not to include some features in your version, you may wish to edit the manual page less.man and the help page help.c to remove the descriptions of the features which you are removing.
Type "make" and watch the fun.
If the make succeeds, it will generate the programs "less.exe" and "lesskey.exe" in your current directory. Test the generated programs.
Make sure you have the emx runtime installed. You need the emx DLLs emx.dll and emxlibcs.dll and also the termcap database, termcap.dat. Make sure you have termcap.dat either in the default location or somewhere in a directory listed in the PATH or INIT environment variables.
When satisfied that it works, you may wish to install less.exe, lesskey.exe and scrsize.exe in a directory which is included in your PATH. scrsize.exe is required only if you use a terminal emulator such as xterm or rxvt.

======================================================================= INSTALLATION (OS-9 systems only, with Microware C or Ultra C)

Move the distributed source to its own directory.
If you are using Microware C, rename Makefile.o9c to Makefile. If you are using Ultra C, rename Makefile.o9u to Makefile.
Check the Makefile to make sure the definitions look ok.
If you wish, you may edit defines.o9 to remove some optional features. If you choose not to include some features in your version, you may wish to edit the manual page less.man and the help page help.c to remove the descriptions of the features which you are removing.
Type "dmake" and watch the fun. The standard OS-9 "make" will probably not work. If you don't have dmake, you can get a copy from os9archive.rtsi.com.
If the make succeeds, it will generate the programs "less" and "lesskey" in your current directory. Test the generated programs.
When satisfied that it works, if you wish to install it in a public place, type "dmake install". See step 6 of the Unix installation instructions for details on how to change the default installation directories.
