19: =========================================================================
1.1 etheisen 20:
21: This is the distribution of "less", a paginator similar to "more" or "pg".
1.2 mbalmer 22:
1.1 etheisen 23: The formatted manual page is in less.man.
24: The manual page nroff source is in less.nro.
25: Major changes made since the last posted version are in NEWS.
26:
27: =======================================================================
28: INSTALLATION (Unix systems only):
29:
1.2 mbalmer 30: 1. Move the distributed source to its own directory and unpack it,
31: if you have not already done so.
1.1 etheisen 32:
33: 2. Type "sh configure".
34: This will generate a Makefile and a defines.h.
35: Warning: if you have a GNU sed, make sure it is version 2.05 or later.
36:
1.2 mbalmer 37: The file INSTALL describes the usage of the configure program in
38: general. In addition, these options to configure are supported:
39:
40: --with-editor=program
41: Specifies the default editor program used by the "v" command.
42: The default is "vi".
1.3 ! shadchin 43:
1.2 mbalmer 44: --with-regex=lib
45: Specifies the regular expression library used by less for pattern
46: matching. The default is "auto", which means the configure program
47: finds a regular expression library automatically. Other values are:
48: posix Use the POSIX-compatible regcomp.
49: pcre Use the PCRE library.
50: regcmp Use the regcmp library.
51: re_comp Use the re_comp library.
52: regcomp Use the V8-compatible regcomp.
53: regcomp-local Use Henry Spencer's V8-compatible regcomp
54: (source is supplied with less).
1.3 ! shadchin 55: --with-secure
! 56: Builds a "secure" version of less, with some features disabled
! 57: to prevent users from viewing other files, accessing shell
! 58: commands, etc.
! 59:
1.2 mbalmer 60:
1.1 etheisen 61: 3. It is a good idea to look over the generated Makefile and defines.h
62: and make sure they look ok. If you know of any peculiarities of
63: your system that configure might not have detected, you may fix the
1.2 mbalmer 64: Makefile now. Take particular notice of the list of "terminal"
65: libraries in the LIBS definition in the Makefile; these may need
66: to be edited. The terminal libraries will be some subset of
67: -lncurses -lcurses -ltermcap -ltermlib
1.1 etheisen 68:
69: If you wish, you may edit defines.h to remove some optional features.
70: If you choose not to include some features in your version, you may
71: wish to edit the manual page "less.nro" and the help page "less.hlp"
72: to remove the descriptions of the features which you are removing.
1.2 mbalmer 73: If you edit less.hlp, you should run "make -f Makefile.aut help.c".
1.1 etheisen 74:
75: 4. Type "make" and watch the fun.
76:
1.2 mbalmer 77: 5. If the make succeeds, it will generate the programs "less",
78: "lesskey" and "lessecho" in your current directory. Test the
79: generated programs.
1.1 etheisen 80:
81: 6. When satisfied that it works, if you wish to install it
82: in a public place, type "make install".
83:
84: The default install destinations are:
1.2 mbalmer 85: Executables (less, lesskey, lessecho) in /usr/local/bin
86: Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
1.1 etheisen 87: If you want to install any of these files elsewhere, define
1.2 mbalmer 88: bindir and/or mandir to the appropriate directories.
1.1 etheisen 89:
90: If you have any problems building or running "less", suggestions,
1.2 mbalmer 91: complaints, etc., you may mail to the author at markn@greenwoodsoftware.com.
1.1 etheisen 92:
93: Note to hackers: comments noting possible improvements are enclosed
94: in double curly brackets {{ like this }}.
1.3 ! shadchin 95:
! 96: (Note that the above note was originally written at a time when
! 97: "hackers" most commonly meant "enthusiastic and dedicated computer
! 98: programmers", not "persons who attempt to circumvent computer security".)
1.1 etheisen 99:
100:
101:
102: =======================================================================
1.2 mbalmer 103: INSTALLATION (MS-DOS systems only,
104: with Microsoft C, Borland C, or DJGPP)
1.1 etheisen 105:
106: 1. Move the distributed source to its own directory.
1.2 mbalmer 107: Depending on your compiler, you may need to convert the source
108: to have CR-LF rather than LF as line terminators.
1.1 etheisen 109:
1.2 mbalmer 110: 2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
111: If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
112: If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
1.1 etheisen 113:
114: 3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
1.2 mbalmer 115: are correct. CC should be the name of your C compiler and
116: LIBDIR should be the directory where the C libraries reside (for
117: Microsoft C only). If these definitions need to be changed, you can
118: either modify the definitions directly in MAKEFILE, or set your
119: environment variables CC and/or LIBDIR to override the definitions
120: in MAKEFILE.
1.1 etheisen 121:
1.2 mbalmer 122: 4. If you wish, you may edit DEFINES.DS to remove some optional features.
1.1 etheisen 123: If you choose not to include some features in your version, you may
1.2 mbalmer 124: wish to edit the manual page LESS.MAN and the help page HELP.C
1.1 etheisen 125: to remove the descriptions of the features which you are removing.
126:
1.2 mbalmer 127: 5. Run your "make" program and watch the fun.
128: If your "make" requires a flag to import environment variables,
129: you should use that flag.
1.1 etheisen 130: If your compiler runs out of memory, try running "make -n >cmds.bat"
131: and then run cmds.bat.
132:
1.2 mbalmer 133: 6. If the make succeeds, it will generate the programs "LESS.EXE" and
134: "LESSKEY.EXE" in your current directory. Test the generated programs.
1.1 etheisen 135:
1.2 mbalmer 136: 7. When satisfied that it works, you may wish to install LESS.EXE and
137: LESSKEY.EXE in a directory which is included in your PATH.
1.1 etheisen 138:

1.1 etheisen 153: If you choose not to include some features in your version, you may
1.2 mbalmer 154: wish to edit the manual page less.man and the help page help.c
1.1 etheisen 155: to remove the descriptions of the features which you are removing.
156:
157: 5. Type "make" and watch the fun.
158:
1.2 mbalmer 159: 6. If the make succeeds, it will generate the programs "less.exe" and
160: "lesskey.exe" in your current directory. Test the generated programs.
161:
162: 7. When satisfied that it works, if you wish to install it
163: in a public place, type "make install".
164: See step 6 of the Unix installation instructions for details
165: on how to change the default installation directories.
166:

178:
179: 4. If you wish, you may edit defines.o2 to remove some optional features.
180: If you choose not to include some features in your version, you may
181: wish to edit the manual page less.man and the help page help.c
182: to remove the descriptions of the features which you are removing.
183:
184: 5. Type "make" and watch the fun.
185:
186: 6. If the make succeeds, it will generate the programs "less.exe" and
187: "lesskey.exe" in your current directory. Test the generated programs.
1.1 etheisen 188:
189: 7. Make sure you have the emx runtime installed. You need the emx DLLs
190: emx.dll and emxlibcs.dll and also the termcap database, termcap.dat.
191: Make sure you have termcap.dat either in the default location or
192: somewhere in a directory listed in the PATH or INIT environment
193: variables.
194:
195: 8. When satisfied that it works, you may wish to install less.exe,
1.2 mbalmer 196: lesskey.exe and scrsize.exe in a directory which is included in
197: your PATH. scrsize.exe is required only if you use a terminal
198: emulator such as xterm or rxvt.

218: 5. Type "dmake" and watch the fun.
219: The standard OS-9 "make" will probably not work. If you don't
220: have dmake, you can get a copy from os9archive.rtsi.com.
221:
222: 6. If the make succeeds, it will generate the programs "less" and
223: "lesskey" in your current directory. Test the generated programs.
224:
225: 7. When satisfied that it works, if you wish to install it
226: in a public place, type "dmake install".
