Well, I like eroff, and have found the man set very good untill now, but I am stumped. Can anyone shed some light on this? Ok, I have a standard text file written with the mm macros, pic, and tbl sections. Now, I would like to include a postscript segment at the TOP of my file, and then send the entire thing through eroff to a postscript printer. Although this is not important, my command line will look something like this: tbl file | pic -D | eroff -mm -dps The man on page 2-13 says that I have to append the \X'code="postscriptline"' stuff to EACH line in my postscript file that I want to include in my troff file (up to 80 chars per line max). This is NOT acceptable, as I do not wish to have to modify EACH and EVERY line of my postscript include file. IS THERE ANY EASIER WAY TO DO THIS???? Can I add my postscript file into header file (must be there for eroff somewhere) that eroff (must?) send to the postscript printer with the -dps command? And if this is possible, is there someway to specify via command line option which header file to use? -- Mark Hilliard {ethos,fthood,u1100a}-----\ N2HHR rutgers!rochester!kodak!pcid!gizzmo!mark \-->gizzmo!mark

I had the same need, to add a new function definition to the postscript prolog that eroff puts at the head of the output file. After battling Chapter 2 of the eroff manual a while I called Elan tech support and was given this undocumented gimmick: \!!prologcode@pathname... for example \!!prologcode@/usr/fred/personal.ps.defs This has to be processed before any text; i.e. it can follow macro definitions and other dot commands so long as it comes before any output data is generated. Write the output file to disk instead of the printer and examine it to make sure the code goes where you want it go. By the way, since this IS undocumented, don't blame me if they drop it next release - but for now it works pretty well. /////// / David Cortesi {pyramid|uunet}!infmx!cortesi ////// // /////////////////////////////////// //// / /// Informix Software // // /// / //// 4100 Bohannon Drive // (aphorism goes here) // // / ///// Menlo Park, CA 94025 // // / //////// (415) 926-6300 ///////////////////////////////////

I am talking about Eroff version 2.2 for UNIX. The machine is an AT&T UNIXpc. Use the .cL, .cR, .cC, or .cS graphics inclusion macros as documented on page 2-1. To get the graphic (Postscript code) at the beginning of your material, note the sentence just before the "A.3 GRAPHICS/CODE INCLUDE RESTRICTIONS" header on page 2-4. "If no text has been output yet, you may force the image to be output before any text by calling the .fI macro. This will cause the image to be output without a text line above it." I have discovered that the following works: .P! postscriptfile .fI The purpose of \X'code="postscriptline"' is to be imbedded in your Eroff code to emit the "postscriptline" code into the generated Postscript. It is not a 'wrapper' for each line of your Postscript code. The Postscript code inserted by either method is enclosed in a 'save' and 'restore' pair. This is easy enough to escape; start your code with a 'restore' and end it with a 'save'. Or you can include your custom prologue code with either of the following lines before any text (not macros) in Eroff input: \X'prologcode="short piece of Postscript code"' or \X'prologcode@file' You should replace "file" with your own file name. As both of these methods are documented (chapter 2: pages 12 to 14), I do not expect them to go away in the 'next release.' This last comment is in response to message id <1893@infmx.UUCP>. This is material I learned last night by reading the manual and experimenting with my new printer. I was wanting to put logos first on letters. Randolph J.

They have not dropped it, they changed the syntax to \X'prologcode@pathname' and DOCUMENTED it. This is based on EROFF Release 2.2 for Unix.

This is based on EROFF Release 2.2 for Unix. As it turns out, the \!!prologcode ... should be used, rather than \X'prologcode ...' for PostScript, because by the time troff outputs the pass-through to the driver with \X it has already started emitting positioning commands. When the PostScript driver sees any positioning or text commands it closes out the prolog and starts working within a save/restore context for the first page, and any additions to the prolog are disallowed. The \!! pass-through is totally transparent, and no formatting commands are output before it *if* the \!! commands are at the beginning of the source file. This way the driver will see the prologcode command before it has closed out the prolog and the PostScript code will be added to the prolog. Unfortunately, the Eroff release 2.2 manuals had been printed before all of the code had been finalized, and for this reason we are leaving the (currently undocumented) \!! command in Eroff, and it will be re-documented in later revisions of the manual. The \!!prologcode usage has been documented in the Eroff 2.2 READ.ME file for the last year or so. Further questions should be directed to the Elan support staff or to me (support@elan.com or jlo@elan.com).

This is based on EROFF Release 2.2 for Unix. In the latest rev of our manual, both forms are included. Both syntaxes are supported in release 2.2 and will indeed continue to be supported in the future. With prologcode, the 1st version with \!! is actually preferable because \X can spit our some positioning stuff first that you might not want when you do a prologue. The READ.ME file included with all Eroff distributions discusses this.

This is based on EROFF Release 2.2 for Unix. Not quite. I am familiar with the three documented ways of putting postscript into eroff output, as given in chapter 2 of the manual for eroff 2.2. They are: \X'code="any postscript one-liner"' \X'code@pathname_of_ps_code_file' \X'prologcode@pathname_of_ps_defs_file' I have used the first two successfully; they are for in-line code. The third, for defining new functions in the header, will not work for me; no matter where in the source file or macro libraries I put it, it returns the error message: Warning: PostScript prolog code must be at beginning of file Code @ "pathname_from_command" ignored After struggling with it, I called the ever-helpful Elan tech support crew, and was given the undocumented escape code \!!prologcode@pathname as a work-around. It worked where the \X escape did not. I repeat, I have no assurance that Elan means to support this, or document it, or fix \X'prologcode', or what. If \X works for you, you should use it. If not, you can try \!! . /////// / David Cortesi {pyramid|uunet}!infmx!cortesi ////// // /////////////////////////////////// //// / /// Informix Software // // /// / //// 4100 Bohannon Drive // (aphorism goes here) // // / ///// Menlo Park, CA 94025 // // / //////// (415) 926-6300 ///////////////////////////////////
