However, the \mark _insists_ on finding its argument in braces: \mark{0} is good, and \mark 0 gives an error msg. Hm. Lessee, can I do that too?

Does anyone know of a public domain (shareware, etc.) program which will create TFM files for Adobe PostScript fonts (generally from AFM files) suitable for OzTeX on the Macintosh? The program does not need to execute on the Mac, but that would be a bonus. If there is sufficient interest/response, I will summarize back to the newsletter. John Dundas Jet Propulsion Lab dundas@sapphire.jpl.nasa.gov ----------------------------------------------------------------------------- Date: Tue, 23 Jan 90 23:08:00 GMT From: Chris Thompson Subject: VF files and DVI-to-DVI converters Keywords: TeX, dvi files, virtual fonts Reading, in rapid succession, Don Knuth's specification of VF format (TeXhax #11-12) and the article by Stephan v. Bechtolsheim in TUGboat Vol.10 No.3 about DVI-to-DVI converters, I had the following thought. It would be possible to process a DVI file that contains references to virtual fonts, and generate another which contains no such references. Indeed, this can be done simply using the VF files, without even the need to read the TFM files for the non-virtual fonts referred to. Roughly, if the currently selected font is virtual, one replaces by {DVI from the VF file} & by {DVI ...} adjusting the font numbers carefully (reassigning font numbers is a standard trick in DVI-to-DVI processors). One also needs to check for the case, which will never arise in practice, in which the DVI from the VF file uses (or , , ) before w has been set locally. This isn't quite as good as putting support for VF files in the DVI-to-device program, because the command above should be treated as a character escapement, rather than white space, for the purposes of `DVItype-style pixel rounding'. (The effect is liable to be that one effectively gets `maxdrift = 0' for material set in the virtual font.) However, as a stopgap measure until all your favourite DVI drivers are enhanced to support VF files, such a program might be extremely useful. When Don says `I fully expect that all people who have implemented DVI drivers will ... be unable to resist installing a VF capability into their own software during the first few months of 1990', I fear his tongue must be in serious danger!

For example, she would be satisfied with the output if every fifth output line is numbered (left or right margin) like that: 1 blah blah blah .. kukkuu ja kukkuu (in Finnish) blah blah xxxx xxxx x x xx x xxxxx x x x xx xx blah blah xxxx xxxx xx x xx xxxx xxxxxx x xxxxx blah xxxx kukkuu ja kukkuu ja kukkuu ja kukkuu 5 blah blah kukkuu ja kukkuu ja kukkuu ja kukkuu blah ... My question is: Is it possible to make a TeX macro to do this kind of automatic line numbering?

Let me merely begin by reporting what seems like near success. I have managed, after much experimentation and many helpful suggestions from people over the network, in getting metafont to produce tfm files and gf files with any prescribed magnification. All that was required was to type mode=localfont; mag=7.5; (or some other number instead of 7.5). In this case, one gets a file with extension .1500gf . I also succeeded in getting the tools in mf84/MFware to compile and work, so I was able to take the gf file and produce a dvi file. If I remember right, gftodvi wanted to have gray.tfm and logo8.tfm available, but I was able to produce them using metafont, as described above. In the case of gray.tfm, it was really grayf.tfm suitably renamed. I am stuck trying to print out the .dvi file . I was aware that one could hack the makefile for dvialw by changing FONTPATH and changed it to one of my own directories. Tonight, I discovered by reading the source code for dvialw that one can overrule whatever the makefile defines FONTPATH to be by setting the environment variable TEXFONTS appropriately. So I can get it to look anywhere for fonts or perhaps I can give it a number of directories, e.g. /usr/lib/tex/fonts:. However, the struggle is not over. For some reason, even though it knows all the places to look, dvialw claims it is unable to open the font files. The files it wants to see are: gray.1500gf (it will probably take a lower number) logo8.1500gf cmr8.1500gf (if I remember right) cmtt10.1500gf (ditto) I have cmr8.1500pxl and cmtt10.1500pxl in my directory and I produced gray.1500gf and logo8.1500gf in the manner described above, i.e. I took the .mf files in /usr/tex/mf84/MFfonts/(gray|logo) and modified them by adding the stuff about mode=localfont and mag=7.5 But for some reason, dvialw thinks it can't open the font files. What could possibly make dvialw think it can't open a font file that is right under its nose even after it has been told where its nose is ? If anyone has any illuminating comments, I would very much like to hear them. I feel that I am very close to being able to print out the .dvi files produced by gftodvi but for 2 cents of useful information.

Braams" Subject: layout.sty, bug repair and reversemarginpars Keywords: macro, layout.sty Hi all, I have a file called layout.sty, the only other identification is that it claims to be from TUGboat Volume 9 Number 1. It is a very handy to tool, but there was a bug and a missing feature in it. I herewith send my modified copy of the file, I indicated the places where I changed something with %% JB ... The bug was a missing backslash in the table which displays the values of various parameters. A missing feature was that the macro's didn't check the value of the flag \if@reversemargin and always put the marginal notes on the `outside' of the text.

Subject: *** Updated METAFONT, .BUG files available from Aston Archive *** Keywords: METAFONT, .BUG files This morning, I picked up some recently revised files from Labrea.Stanford.edu There was an updated mf.web, correcting the bug which I reported in my Jan 11th announcement of the port of MF v1.9 to VMS. There was also a revised version of mf84.bug, and I took the opportunity to collect the other .bug files available at Labrea. All these files have been placed into the archive at Aston University, as follows: [TEX-ARCHIVE.DIGESTS.UPDATES]CM85.BUG [TEX-ARCHIVE.DIGESTS.UPDATES]LATEX.BUG [TEX-ARCHIVE.DIGESTS.UPDATES]MF84.BUG [TEX-ARCHIVE.DIGESTS.UPDATES]TEX82.BUG [TEX-ARCHIVE.METAFONT.MFDIR.NEW]MF.WEB (Older versions of the various .BUG files, of varying antiquity, and scattered across different directories [some more than once] in the archive, have been deleted.) I have also created a full listing of the tex tree at Labrea, and this too is available from the Aston Archive; listing created 10:45GMT 23rd January: [TEX-ARCHIVE.DIGESTS.UPDATES]LABREA.LIS I hope to provide an updated version of this listing at regular intervals. Since there's only a very minor change between this latest mf.web and the previous version (dated, at Aston, 11th Jan 1625GMT), I've also provided a change file that can be used, BY VMS USERS ONLY, to produce the latest version from that earlier version; just collect: [TEX-ARCHIVE.METAFONT.MFDIR.NEW]MF.WEB_UPD and apply EDIT/SUM MF.WEB/UPDATE=MF.WEB_UPD to activate the SUMSLP editor. I've also revised: [TEX-ARCHIVE.METAFONT.MFDIR.NEW.VMS]MF.CH to match the new .WEB file; again, those who have already collected the previous edition (dated 11th Jan at 2047GMT) can use: [TEX-ARCHIVE.METAFONT.MFDIR.NEW.VMS]MF.CH_UPD to save the nausea of transferring the whole of the new change file.
