3. as fast as he could type This demonstrates a completely new paradigm of type face design and creation which many graphic de signers will find alien but which evidently works for some people at least for smallish projects such as the punk typeface People interested in METAFONT should be aware that in addition to past issues of TUGboat TEXhax and UKTRxX Don Hosek s network mag azine TmeXMaG has regularly included information about fonts and is required reading for META FONTers Volume 2 issue 5 in particular was ded icated to non English T X and discussed Icelandic German French ancient Irish and the problems of foreign language hyphenation Earlier issue of TeX MaG have also contained technical descriptions of TEX font file formats etc For information on sub The Many Faces of TFX a Survey of Digital METAfonts TUGboat 9 2 1988 131 151 2 A Punk Meta font TUGboat 9 2 1988 152 168 TUGboat Volume 9 1988 No 3 scriptions or back issues contact Don Hosek net work address DHosek HMCVAX Bitnet Once again I am beholden to those who pro vided the information I have merely marshalled be low 1 Music UKTFX 1988 issues 28 and 29 carried an exchange of information recently concerning the use of TEX to typeset music This very challenging application has been receiving some attention and the work to date was announced in the Music Research Digest Thence it found its way to UKTEX

5. 246 Further Faces Dominik Wujastyk since The Many Faces of TEX appeared in issue 9 2 of TUGboat information about METAfonts has continued to flow in thankfully in somewhat di minished quantities Since I wrote the last article I have moved from the USA to England and al though all the network services are available here too at a price in practice Janet is not as open a medium as the Internet and I feel it is more likely now that I might miss news about fonts especially if it appears in UseNet to which I currently have no access I particularly miss the astonishing power of the American brand of FTP However the vast TEX archive at Aston maintained by Peter Abbott is more comprehensive than any other I know of and NIFTP and mail server access to this archive greatly compensates for the sense of network isola tion All the same if you know of any METAfonts that I have not mentioned I would be glad of the news 3 For new subscribers to TUGboat issue 9 2 con tained a survey of the existing fonts known to be available for use with TeX including non roman scripts other styles and much besides That is sue also included METAFONT code and examples for a new punk METAfont called just PUNK by Don Knuth Perhaps the most extraordinary part of that article is Don s description of how he coded the font extremely rapidly and with no reference at all to drawings for the letters from V to Z producing the METAFONT code

FX 1988 issue 29 to the effect that he had received a number of e mail requests for more information from around the world While pleased at the level of interest in his research he explained that just at the moment he is not in a good position to reply to these queries My problem is that right now I am at a critical stage of writing my Master s thesis on this topic and I simply cannot afford the time to reply to all the letters I am re ceiving Also while I would love to send everyone a copy of my recent report that will take time and money I don t have I m going to try and convince my University to take care of it On a more positive note my plans for the near future include finishing my the sis by this December preparing a paper based on it for one of the computing jour nals I ll announce which one when I know and preparing a distribution version of my mark setting prototype The prototype cannot be distributed as is because it s written for an experimental programming 3University of Western Ontario Technical Report 171 247 system that only existed here and is now obsolete It won t take much effort to turn it into straight C code though So while I appreciate the interest in my work I just wanted to let the read ers know that ll be a bit of a hermit for the next few months and that right now I don t really have anything in the way of software to distribute Contact or not

11. automata flow diagrams etc I think the existing typesetting paradigm can be extended to marksetting where a mark is any kind of symbol not necessarily of fixed form like a text character but possi bly dependent on one or more parameters e g 2 endpoints for a line segment I TUGboat Volume 9 1988 No 3 am trying to develop a design for a general purpose marksetting system which can be used as a software basis for any number of specialized formatting programs i e a dif ferent front end program for each class of notation I am doing this research towards a Mas ter s thesis in Computer Science which I hope to complete before the end of Decem ber In the meantime there is one techni cal report which discusses my earlier work on music setting including the prototype and contains some early ideas about gen eral mark setting My approach was simpler than that of Schofer and Steinbach I used PostScript s powerful graphic primitives to define parametrized procedures to create things like beams and slurs Schofer and Stein bach s fonts simply include huge numbers of different beam and slur characters at dif ferent slants etc to handle a reasonable set of cases The results look very good Dunne has been somewhat overwhelmed by re sponses to this report on his work which was in fact not really intended for general distribution He followed up with a note which appeared in UKT

13. mar and his wife Lakshmi about TeluguTpRx is as follows 249 We have decided on the grid framework for the font We also have thought about dif ferent global variables that could be used to control various features of the font We have decided on a set of primitive curves These are like subroutines that can be used by different letters Some of these are coded in METAFONT Only control points are de termined We are yet to determine the stroke thickness and pen angles at the con trol points Since we are not imitating any font it takes a lot of time trying to ensure that various curves are correct Our ap proach is to make a rough sketch and then determine the control points Then we it erate by changing control points until the curve is satisfactory But the most impor tant thing to keep in mind is that all the curves must be consistent and be able to blend harmoniously We essentially have the framework for Telugu font ready But a lot of coding remains In our spare time we will work on it Some issues still remain un resolved We are not sure what we should do to support transliteration of Sanskrit in Telugu That means adding a lot of sub scripts superscripts Our file structure is basically like that in CMR We have parameter base driver codes and program right now empty files T JST px Emma Pease emma csli stanford edu mailed me on July 5 1988 with a correction about the avail ability of JTEX a Tops 20 v

17. the existing Computer Modern family may be cre ated with any design size For example most of us when requiring an llpt CMR will use CMR10 at magstep half Apparently this is not satisfactory to the most discerning and Sauter s algorithms permit one to generate a true CMR11i face They go further of course and permit the generation of any of the CM faces in any reasonable point size This is done by algorithms that interpolate or extrapolate from the values used by Knuth in the METAFONT parameter files for CM If a standard value such as 10pt is chosen then Sauter s algorithms will pro duce CM fonts identical to the standard ones The TFM files for all sizes match exactly Don Hosek s TeXMaG volume 2 number 4 gives further details of Sauter s work and notes that some of the fonts may start looking bad at larger sizes lacking inter character space and so on Don has prepared a version of Sauter s work tailored for use on a PC which is available from him See the TeXMaG article for details 251 Output Devices TEX Output Devices Don Hosek The device tables on the following pages list all the T X device drivers currently known to TUG Some of the drivers indicated in the tables are con sidered proprietary Most are not on the standard distribution tapes those drivers which are on the distribution tapes are indicated in the listing of sources below To obtain information regarding an interface if it is s
