=========================================================================
|
|
|
|
This is the distribution of "less", a paginator similar to "more" or "pg".
|
|
|
|
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 systems only):
|
|
|
|
1. Move the distributed source to its own directory and unpack it,
|
|
if you have not already done so.
|
|
|
|
2. 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:
|
|
posix Use the POSIX-compatible regcomp.
|
|
pcre Use the PCRE library.
|
|
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).
|
|
--with-secure
|
|
Builds a "secure" version of less, with some features disabled
|
|
to prevent users from viewing other files, accessing shell
|
|
commands, etc.
|
|
|
|
|
|
3. 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".
|
|
|
|
4. Type "make" and watch the fun.
|
|
|
|
5. If the make succeeds, it will generate the programs "less",
|
|
"lesskey" and "lessecho" in your current directory. Test the
|
|
generated programs.
|
|
|
|
6. 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.
|
|
|
|
If you have any problems building or running "less", suggestions,
|
|
complaints, etc., you may mail to the author at markn@greenwoodsoftware.com.
|
|
|
|
Note to hackers: comments noting possible improvements are enclosed
|
|
in double curly brackets {{ like this }}.

=======================================================================
|
|
INSTALLATION (MS-DOS systems only,
|
|
with Microsoft C, Borland C, or DJGPP)
|
|
|
|
1. 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.
|
|
|
|
2. 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.
|
|
|
|
3. 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.
|
|
|
|
4. 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.
|
|
|
|
5. 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.
|
|
|
|
6. If the make succeeds, it will generate the programs "LESS.EXE" and
|
|
"LESSKEY.EXE" in your current directory. Test the generated programs.
|
|
|
|
7. 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++)
|
|
|
|
1. Move the distributed source to its own directory.
|
|
|
|
2. If you are using Borland C, rename Makefile.wnb to Makefile.
|
|
If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
|
|
|
|
3. Check the Makefile to make sure the definitions look ok.
|
|
|
|
4. 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.
|
|
|
|
5. Type "make" and watch the fun.
|
|
|
|
6. If the make succeeds, it will generate the programs "less.exe" and
|
|
"lesskey.exe" in your current directory. Test the generated programs.
|
|
|
|
7. 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)
|
|
|
|
1. Move the distributed source to its own directory.
|
|
|
|
2. Rename Makefile.o2e to Makefile.
|
|
|
|
3. Check the Makefile to make sure the definitions look ok.
|
|
|
|
4. 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.
|
|
|
|
5. Type "make" and watch the fun.
|
|
|
|
6. If the make succeeds, it will generate the programs "less.exe" and
|
|
"lesskey.exe" in your current directory. Test the generated programs.
|
|
|
|
7. 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.
|
|
|
|
8. 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)
|
|
|
|
1. Move the distributed source to its own directory.
|
|
|
|
2. If you are using Microware C, rename Makefile.o9c to Makefile.
|
|
If you are using Ultra C, rename Makefile.o9u to Makefile.
|
|
|
|
3. Check the Makefile to make sure the definitions look ok.
|
|
|
|
4. 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.
|
|
|
|
5. 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.
|
|
|
|
6. If the make succeeds, it will generate the programs "less" and
|
|
"lesskey" in your current directory. Test the generated programs.
|
|
|
|
7. 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.
