According to the Adobe specification <http://partners.adobe.com/public/developer/en/acrobat/5411.ToUnicode.pdf> both existing pdfr-* files already violate at least one of the following two requirements: /CMapType 2 def ... 1 begincodespacerange <0000> <FFFF> endcodespacerange You can either define a range (for example for A-Z, 0-9, ...) or single characters.

Euro-letter encoding (was: Dense Encoding)

Hans Hagen said this at Sun, 21 Aug 2005 18:36:21 +0200: >so the advised font encodings will be: texnansi, qx, t5, dense Okay, thinking about it, dense isn't a great name, either. Just about all the 8-bit encodings are dense--they're just dense with different stuff. So with that in mind, I present euro-letters: <http://homepage.mac.com/atl/tex/euro-letter.pdf> <http://homepage.mac.com/atl/tex/euro-letter.zip> In the course of things, I found that for whatever reason, the unic-030 (VN) vector was off by two slots. I added [ST]commaaccent to enco-uc (should be in enco-def, too) and unic-002. The key files, however, are enco-el.tex and eurolett.enc. The tester file was brought to life simply by installing: texfont --ma --in --ve=public --co=lm --so=auto --en=eurolett \ --pat="lmvtt*" Please run with normal text--anything you can get your hands on. I am nearly a monoglot, and don't have a lot of stuff lying around that would actually put this stuff to the test. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

Sure. (didn't send to main list 'cos it's rough, still) I notice in the context of this latest discussion that I use Eth as a stand-in for Dcroat, mostly because I know slightly more about Icelandic than I do about Croatian. Although these slots are precious, perhaps I shouldn't do that. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

Hi, so, according to walters mail, we have actually two files: dense.enc dense-<whatever names the type 1 font uses>.enc (used in map files) my impression is that we can assume that commercial fonts use the adobe scheme, but i'm not that sure how well tex fonts behave Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

encodings
by Hans Hagen 19 Aug '05

19 Aug '05

Hi, This encoding mess ... somehow i got the feeling that we should start shipping proper tfm files, i.e. texnansi ec qx char (adam's new one) ecx (mojcs's fixed ec) I can probably convince te polish font guys and we need a similar named set (generated of copied) for the abotu 15 free fonts on tex live. There is no point is keeping in tune with old stuff and latex-needs-it-this-way-so-we-cannot-fix-it situation. It's taking too much time. (Comparable with the patterns mess, i now just ship them). In the end we can set up a project that maintains these sets.

Garden server moving
by Patrick Gundlach 19 Aug '05

19 Aug '05

Hi, I'll move the garden server to a slightly faster and bigger machine. I have found out that a 5 gig disk is just not enough for all the fine ConTeXt thingies out there. I guess that I do the work on monday/tuesday. Just in case someone wants to store things on the machine (museum etc...), this can be done soon.

kpse
by Hans Hagen 16 Aug '05

16 Aug '05

Hi, The latest distribution has an experimental ruby kpse class in kpsefast.rb (expects updates -). As far as i can measure it's not slower than native kpse and once loaded in a ruby prog it's faster of than reinvoking kpse each time; it can (optionaly) dump the database in a home/temp path which halves loading time. I will probably use this mechanism in the coming texexec/texutil (maybe also in texmfstart). The associated variant of kpsewhich is 'tmftools' (no help yet). Apart from basic kpsewhich functionality it will harbor more tree tools. texmfstart tfmtools --analyze --root=/whatever/tex texmfstart tfmtools --analyze --root=/whatever/tex --trees=texmf,texmf-local can be very instructive on duplicate files on your machine and point you to problems. It has a --delete option which can be used as follows texmfstart tfmtools --analyze --root=/whatever/tex --delete "texmf-local/fonts/.*/lm" this will remove dups in texmf-local (to be sure, one needs to pass --force as well) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

lua
by Hans Hagen 08 Aug '05

08 Aug '05

Hi, Recently i've started looking into Lua, a language meant for embedding in programs. It has a small footprint, and by reading themanukl i get the impression that it's a pretty well designed and clever language. So (after playing with lua and scite, which has it embedded) i started wondering about including lua in pdftex. Of course i'm dependent on others but i'm curious abotu wat members of this list think of it. It has quite a clever function model. Especially because it has a small footprint (some 100-150 k) it would add a lot to pdftex but at little cost. think of on the one hand: \dimen0=\lua{tex.todimen(tex.thedimen(0)+tex.thedimen(2)} kind of things, or \setbox2=\hbox to \lua{tex.todimen(somevar)} {\lua{tex.text("abcde")}} and alike. Of course the interface is to be determined, but a startingpoint can be access to box dimensions and registers and the ability to pipe text (strings) back into teh tex inpt stream. whatdoyouthink ...
