README (6601B)
1 Stuff appears to work, but it's obviously not well tested. I fully 2 expect several iterations before things are correct!! Make sure you 3 can back this out quickly. 4 5 This code supports UTF encoding. Directory dpost.utf is a version that 6 reads UTF encoded files. Directory dpost is DWB 3.3 source and should be 7 close to what you're currently using. Main source code changes were in 8 dpost.utf (files font.h, font.c, and dpost.c). Select either dpost or 9 dpost.utf in TARGETS in postscript.mk. Both build and install a program 10 called dpost!! 11 12 dpost.utf is more general and includes code that lets it read either 13 format. Only catch is troff must tell it (with x E UTF) that the file 14 is UTF and troff currently doesn't output encoding info, so you're 15 stuck with two post-processors! 16 17 Added common/rune.h and common/rune.c so code can be compiled elsewere. 18 Both files are only used by dpost. Remove RUNELIB in commmon/rune.h if 19 fullrune(), chartorune(), and runetochar() are available on your system. 20 You will also need to set READING in common/gen.h. It controls how dpost 21 (from dpost.utf) reads troff output. It should be UTFENCODING on Plan 9 22 and ONEBYTE elsewhere. If troff includes encoding hint (x E UTF) then 23 READING selects the default which sould be ONEBYTE. 24 25 Leave WRITING (in common/gen.h) set to ONEBYTE. It only controls dpost 26 output and dpost (right now) does not work 100% with UTF.enc. Fix should 27 be easy, but I don't have time now. 28 29 Other translators passed bytes through so only needed slightly modified 30 proglogues and a new encoding scheme (psencoding/UTF.enc). It works for 31 Latin1, but still needs a bit more attention. Prologue changes were easy 32 and only involved adding lines like, 33 34 /show {show} bind def 35 /stringwidth {stringwidth} bind def 36 37 Guarantees text procedures used in prologues aren't operators and can be 38 successfully redefined in UTF.enc. Unbinding means a small but probably 39 not noticeable speed penalty. You may not want to include those changes 40 on other system. 41 42 ------------- 43 Major Changes 44 ------------- 45 46 See the VERSION file. 47 48 ------------------- 49 Tuning The Makefile 50 ------------------- 51 52 Source files, man pages, and low level makefiles can all be updated 53 to reflect settings in postscript.mk in one simple step (described 54 later). In most cases you only need to edit file postscript.mk. 55 56 First save a copy of file postscript.mk. Then adjust the following 57 definitions in file postscript.mk: 58 59 SYSTEM best match for your version of Unix. Current choices for 60 SYSTEM are: 61 62 SYSV - System V 63 V9 - Ninth Edition 64 BSD4_2 - Berkeley (eg. Sun) 65 66 Controls conditional compilation in a few places. 67 68 GROUP group assigned to all installed files 69 70 OWNER owner of everything that's installed 71 72 BINDIR dpost and picpack go here. All other programs go in POSTBIN. 73 BINDIR must already exist - it will not be created during an 74 install. 75 76 HOSTDIR hostresident font directory for PostScript printers. Only 77 used in the font download program. 78 79 FONTDIR width table directory - for troff and most postprocessors 80 81 MAN1DIR command manpages. A command and its manpage are installed 82 together - there's no easy way to avoid it. Setting MAN1DIR 83 to an existing temporary directory (e.g. /tmp) means an 84 install will work but manpages won't go anywhere permanent. 85 MAN1DIR must already exist - it will not be created during 86 an install. 87 88 POSTBIN where most PostScript support programs go. dpost and picpack 89 the exceptions. 90 91 POSTLIB prologues and miscellaneous PostScript files. Primarily for 92 the programs that live in POSTBIN. 93 94 CFLGS common compiler options - used to build CFLAGS in the low 95 level makefiles. CLFGS and LDFLGS are best set on the make 96 command line. 97 98 LDFLGS common link editor options - used to build LDFLAGS in the 99 low level makefiles. LDFLGS and CFLGS are best set on the 100 make command line. 101 102 DKHOST set it to TRUE to compile the DKHOST Datakit support code 103 in postio. Temporarily resets SYSTEM to SYSV if DKHOST is 104 TRUE and SYSTEM is BSD4_2. Ignored if SYSTEM is not SYSV 105 or BSD4_2. 106 107 DKSTREAMS enables streams based DKHOST support in postio when DKHOST 108 is TRUE and SYSTEM is SYSV or BSD4_2. Choices are TRUE, 109 FALSE, or a stream module name (e.g. dknetty or dkty). TRUE 110 selects dknetty. Newer systems may expect dkty. 111 112 ROUNDPAGE must only be set to TRUE or FALSE. TRUE means PostScript 113 translators include code that maps clipping path dimensions 114 into known paper sizes. 115 116 TARGETS the default list of what's built by make. Each target must 117 be the name of a source directory. A target that names a 118 non-existent source directory is ignored. Setting TARGETS 119 on the make command line overrides the default list. 120 121 ------------------- 122 Updating The Source 123 ------------------- 124 125 Whenever file postscript.mk changes you should update source files, 126 man pages, and low level makefiles by typing, 127 128 make -f postscript.mk changes 129 130 ------------------------ 131 More System Dependencies 132 ------------------------ 133 134 The package has been compiled and tested on System V and Ninth Edition 135 Unix Systems and on Sun workstations. Most differences are handled via 136 the SYSTEM definition in postscript.mk. Problems that remain are: 137 138 SYSV - System V 139 Use the native compiler if you're on an internal System V UTS 140 machine. 141 142 V9 - Ninth or Tenth Edition 143 chown is in /etc and chgrp no longer exists - it's been folded into 144 the chown command. You may be forced to build a simple chgrp shell 145 script (put it in your bin) that calls chown. If you're not superuser 146 set OWNER to your login name and GROUP to your group id. 147 148 BSD4_2 - Sun Workstations 149 Use the Bourne shell. chown is should be in /usr/etc. Add /usr/etc 150 to your PATH and export PATH. If you're not superuser set OWNER to 151 your login name and GROUP to your group id. 152 153 ---------------------- 154 Installing The Package 155 ---------------------- 156 157 To build (but not install) the default package (i.e. everything named by 158 TARGETS in postscript.mk) type, 159 160 make -f postscript.mk all 161 162 To build and install the package type, 163 164 make -f postscript.mk all install 165 166 After the package is installed use, 167 168 make -f postscript.mk clobber 169 170 to delete binary files and compiled programs from the source directories. 171 172 To select part of the package define TARGETS on the command line. For 173 example, 174 175 make -f postscript.mk TARGETS="dpost devpost" all install 176 177 builds and installs dpost and the PostScript font tables. Quotes hide 178 white space from the shell. 179
