Roadmap

1:52 p.m.

Hi, this weekend I've met Hans, Hartmut and Taco in Schwetzingen (we attended the christmas party of the Darmstadt TeXies with Hermann Zapf) and we discussed the status and future of pdfTeX. We came down with this "roadmap": 1.40 (200603): - all the current patches plus \primitive et.al - cleanup the code (fewer patchfiles) to have a better starting point for lua - move project to Gforge hosted by Fabrice, and setup a complete code repository there - start of "pdfTeX news" 1.50 - more bits, i.e. use more than 16 (and enough) where possible 1.60 or later - general map file handling for pdfTeX and all programs that use map files - OpenType -- this requires more bits and can be done in steps - lua -- integration can be done post 1.40, but the TeX<->Lua interface needs much testing and developement, so lua will stay experimental for quite some time sometime (i.e. whenever it's ready) - tagged pdf - merging hyperlinks in included documents Best Martin -- http://www.tm.oneiros.de

New subject: 1.40 Schedule

I propose this schedule for 1.40: - alpha, i.e. patches for the not-cleaned-up source code till 2006-01-15 (2006W02) - beta, i.e. code cleanup till 2006-02-12 (2006W06) here we are in feature freeze and can work on the manual and news - rc0 on 2006-02-20 (2006W07) bug hunting! - release on 2006-03-06 (2006W09), i.e. in time for DANTE Berlin. We should also have moved the project to Gforge hosted by Fabrice, and setup a complete code repository there till then. Comments? Best Martin -- http://www.tm.oneiros.de

Martin, At what point do you intend to flatten the web files? My \primitive patch will be uploaded in the weekend or beginning next week (I've been sick through monday afternoon, so I am a bit behind, and now need to prepare for the NTG meeting upcoming friday). Taco

I'd also like to unify our coding style. One easy way to do this is to use indent(1). Any opinions on options to use? The default (i.e. GNU coding standards) with --no-tabs seems OK to me. Best Martin -- http://www.tm.oneiros.de

i've already started to indent everything in reach, see the remark in the headers of some of pdftex's .c files: /* source code indentation by "indent -kr -nut" */ This looks quite natural: KR-mode and no tabs. Regards, Hartmut

That's not about etags, it's about grep, in particular the ability to do "grep ^foo *.c" and find the defn of foo(). Apart from the space (which is abominable) after the function name, I have learned to appreciate this style. -- Olaf Weber (This space left blank for technical reasons.)

Ah. Agreed.

The space is not configurable in the declaration -- only after every function call. And I prefer to have it after calls. On 2005-12-27 09:39:39 +0100, Hartmut Henkel wrote:

do we really want GNUish indentation? like

if (strcmp (fp->tfm_name, nontfm) != 0) { p = (fm_entry *) avl_find (tfm_tree, fp); if (p != NULL) { if (mode == FM_DUPIGNORE)

i would prefer K&R (--k-and-r-style):

if (strcmp(fp->tfm_name, nontfm) != 0) { p = (fm_entry *) avl_find(tfm_tree, fp); if (p != NULL) { if (mode == FM_DUPIGNORE) {

I suggest a tamed k&r: --k-and-r-style --blank-lines-after-procedures --line-length 80 --procnames-start-lines --space-after-procedure-calls --no-tabs /* this does not work in indent 2.2.6 :-( */ --preprocessor-indentation 2 /* this is new in indent 2.2.9 */ this gives if (strcmp (fp->tfm_name, nontfm) != 0) { p = (fm_entry *) avl_find (tfm_tree, fp); if (p != NULL) { if (mode == FM_DUPIGNORE) { Best Martin -- http://www.tm.oneiros.de

I use "grep ^\\w *.c", and also find static and global identifiers. But like I said, I don't really care as long as there is a 'run this command' statement somewhere. Taco

I've started this by merging the change files and want to end up with pdftex1.ch (applied to tex.web) and pdftex2.ch (merged with all the web2c-changes). extra.ch will have to stay, but will be renamed to pdfetex.ch4. Best Martin -- http://www.tm.oneiros.de

What about eTeX? Currently I have pdfetex_web_srcs = $(srcdir)/tex.web \ $(srcdir)/etexdir/etex.ch \ $(srcdir)/etexdir/etex.fix \ $(srcdir)/pdfetexdir/pdfetex.ch1 \ $(srcdir)/pdftexdir/pdftex.ch \ $(srcdir)/pdfetexdir/pdfetex.ch2 and pdftex_web_srcs = $(srcdir)/tex.web \ $(srcdir)/pdftexdir/pdftex.ch So pdftex.web _or_ pdfetex.web would be easy, but having one file for both would be difficult. Shall we simply drop pdftex.web and go for an integrated pdfetex.web? Both TeX and eTeX are very stable. Best Martin -- http://www.tm.oneiros.de

indeed, let's stay with the historic name (of course it's up to thanh to make the final decission on that); for a while i wondered if calling the binary pdftex would make sense, but then we need to adapt too many manuals, tools, etc; Hans

Sure. Thanh, would you please say the final agreement that pdftex means from now "pdftex with all etex extensions"? (no more pdfetex)

Hans, thanks for pointing that. It just means that we have to change at least fmtutil.cnf and make some cosmetic changes is some documentation. I vote for doing that.

So the project is pdfTeX. And the binary is pdftex (current beta has pdfetex)? Changing the name of the binary back to pdftex will cause confusion, as now (teTeX 3/TL2005) the binary used is pdfetex (pdfTeX is just a symlink to pdfetex, changing the binary back to pdfTeX would need the reversed link).

for one or two years we can ship two binaries, pdftex and pdfetex which are just copies, otherwise we get problems on platforms without symlinks, so - compile pdftex - copy it to pdfetex Hans

experimental, may even dissappear in favor of lua stuff (taco will start working on that soon)

Aaa, so if luaTeX might *replace* anything, i belive it makes no sense to write even a word. After tracking all the patches some more doubts: 1. '-etex' cmdline switch is already mentioned in 'pdftex --help' but I couldn't force it to work; the option is 'not recognized' during format creation (pdftex-beta, 1.40.0, 13.02.2006 compiled under Cygwin). 2. \ifabsnum, \ifabsdim; eTeX manual or pdfTeX manual? 3. \primitive, \ifprimitive; to be documented or to be replaced with namespaces? 4. \pdfinsertht, experiments with snapping and kerning (patch #415)?

My idea is: flag as experimental, \primitive may change its behaviour still (depending the outcome of the discussion on sarovar). I do not really expect a namespace solution coming soon. That is to say: i certainly do not have the time to write a functional specification for such an extension. If someone else feels up to that, than I will happily (attempt to) write an implementation, but it would still be too late for 1.40. Cheers, Taco

Sure, but that is because your \ifabsnum is an undefined control sequence, since you are still using 1.30.5 :-) Here is a bit of equivalent plain TeX code that crashes in the same fashion: \def\xx#1{\type{#1}} \starttext \xx {\iffalse} \stoptext The simplest solution (for now) is to start pdftex-t.tex with : \let\ifabsnum\relax \let\ifabsdim\relax Cheers, Taco

We came down with this "roadmap":

1.40 (200603): - all the current patches plus \primitive et.al - cleanup the code (fewer patchfiles) to have a better starting point for lua - move project to Gforge hosted by Fabrice, and setup a complete code repository there - start of "pdfTeX news"

maybe also add hz support for ttf fonts (currently limited to type1; why?) Hans

(currently limited to type1; why?)

The hz algorithm changes the FontMatrix of the font. The FontMatrix is a property of a Type1 font. If you want to do it in a more general way you have to change the PDF text matrix. But though this had been done in dvipdfm, it's not easy. BTW., for the same reason ExtendFont and SlantFont do not work with TTF. Changing the text matrix would be better because currently a font is included more than once if font expansion is used. There is another nasty thing: CFF fonts can have a single font with different font matrices, but there is a restriction in the PDF spec which allows only one FontMatrix for a particular CFF font. Changing the text matrix would have a few advantages: * The file size will be significantly smaller. This did not matter in the past because very few people used font expansion, but with the advent of \autoexpand and microtype.sty it will affect many files now. * ExtendFont and SlantFont will work with TTF fonts as well. * If dvi output is required, pdftex can insert a \special which changes PostScript's matrix in a similar way as it does it for pdf output. This will not work for TTF in dvips, though. Hans, you are the second one who asked (I asked Thanh a few years ago), so I think that the priority is not very high. I think that it should be put on a TODO list. I also recommend to look into Mark Wick's sources. He already solved this problem. What is needed to make dvips able to process TTF? If no subsetting is required, will dvips be able to deal with Type42? Type42 can be created from TTF on-the-fly. Is it difficult to insert the pdftex TTF subsetting code into dvips? It is useful to care about dvi output and dvips because many people ask how to use psfrag and using dvips -E and epstopdf is a simple solution.

well, how about deciding now that it has a high priority; we need to go that direction anyway because soon open type will take over also, as you say, now that pdftex generates the instances itself, hz has become feasible also, when you and i want it, it becomes hard for thanh to ignore it -) since thanh is 'on leave' maybe hartmut sees it as a challenge ... btw, thanks for the explanation Hans

in my understanding it is essential to have "font 16-bitness" on the abstract level of TeX (i.e. metric features; specific glyph representation is very much secondary), not connected to any specific font format like Opentype.

well, if you only want metric info then \wdcode, \htcode, \dpcode,\iccode, \whatevercode can also be a solution (pdftex already has many \*codes associated with characters)

but -since many fonts don't demand much control- it's also a weakness that tex cannot handle for instance afm files directly. since tfm compatibility will remain, some kind of 32 bit native tex format will probably show up (in the past there has been discussions about reading property lists which are extendible instead of tfm files); now that pdftex offers many font related features, it may as well make sense to control such things at the macro level on top of regular fonts and not using a dedicated font format; so, whatever will happen, there will be much control over fonts and how they are used, but a more native and direct support will also be provided.

will lua provide input processing as powerful as OTPs? HH> i dunno, but it will definitely be easier (and documented)

are there any preliminary considerations or descriptions of how it will work (of course not detailed - just to understand the proposed idea of such a replacement of OTPs)?

no, and it's currently also not under discussion, just under consideration; also, overloading and plugins is part of the game (btw i never could find a clear description / explanation of otp's which makes it a mechanism for a happy few while in fact we need mechanisms for the many) Hans

also very essential part of omega/aleph are the 16-bit fonts (or even 32-bit?).

It's certainly better to start with 32 bit rather than to look for volunteers in a few years.
