Snapshot 20060915
by Taco Hoekwater 15 Sep '06

15 Sep '06

Hi, Here we go again. The new snapshot has the following changes compared to 20060908: * There is a new TEX primitive: \formatname. It is similar to \jobname (read-only). In initex, the expansion is empty, otherwise the expansion is the same as the \jobname from the initex run. * the lua "tex" table has been expanded with a few of the 'convert' codes (read-only). The supported ones at this moment are: tex.eTeXVersion tex.OmegaVersion tex.AlephVersion tex.pdftexrevision tex.pdftexbanner tex.pdfnormaldeviate tex.jobname tex.formatname tex.eTeXrevision tex.Omegarevision tex.Alephrevision This list looks haphazard, but it really is not. These are all the cases of the 'convert' internal command that do not require an argument. * The metatables of the subtables like tex.dimen[] etc. are now adjustable from lua (not that I recommend doing that;-)). * On the lua side, there is a new global value: "luaid" It holds the internal id number of this \directlua instance. * There is a new lua table, "callback", that has the single function "callback.register", used to register callbacks. This replaces the previous concoction (see my message about snapshot 20060901). Syntax is : callback.register(<callback name>,function (f) ... end) where the <callback name> is for the moment, either "input_line" or "show_error_hook". This function internalizes the callback function in such a way that you no longer have to worry about \luacallback (which has been removed), nor does it matter if you redefine a function accidentally. The internal testing for callback presence is also quite a bit faster, thanks to this change. Callback assignments are global and the "input_line" always takes effect starting on the next input line to be read from an actual file. * \detokenizedlua has been removed. It is functionally replaced by the new function call tex.write(""). Each argument to each call of tex.write () counts as an input line, but: ** all catcodes on that line are either 'space' (for " ") or 'character' for all others. ** there is no \newlinechar appended. * The implementation of tex.print() has changed as well: ** the very last tex.print() line from a \directlua will no longer have a trailing \newlinechar (this is very convenient when \directlua is used within an \edef) ** tex.print() is quite a lot faster than before, and the total amount of returnable text from a \directlua is now only limited by available system RAM. However, each separate tex.print () argument has to fit in TeX's input buffer. * The new primitive \luastartup can be set inside the format file to specify the lua instance number in which a possible runtime startup.lua script is executed (initex always uses 0) * There is a new primitive \scantextokens. Differences with eTeX's \scantokens are: ** the last line (usually only) from \scantextokens does not have a \newlinechar ** \scantextokens never raises an eof error. This means things like \edef\testone {\scantextokens{\ifnum1=1 true}\else false\fi} are legal input (but potentially dangerous!). * If you say local d = tex.dimen["unknowndimen"] 'd' will now become "nil" instead of raising an error However, tex.dimen["unknowndimen"] = d is still (and probably will remain) illegal Have fun, Taco Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are two new released files: * luatex-snapshot-20060915.tar.gz This is the source tree. * luatex-snapshot-20060915-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). This executable cannot run dynamically loaded lua dlls. Perhaps that can be fixed but I do not know how.

Snapshot 20060908
by Taco Hoekwater 08 Sep '06

08 Sep '06

Hi again, Another friday, another snapshot! While last Wednesday's snapshot was more of a bugfix release, this one adds some extra features. * BIG CHANGE: \directlua now runs \scantokens internally. There is no longer a need to call scantokens yourself, the tex.print() output is now fed straight into a pseudo file. This is quite a bit faster as well as easier to use, but just in case you want it, the old behaviour is still present, under the new name \detokenizedlua * The texio library now has its own (partial) set of I/O commands, so that the standard lua io library is back to the distributed state (no more patched garbage collector) Note: This is really a very small change (it should not have any impact on wellbehaved input files), but I attempt to be complete in these notes, since there is no official documentation yet. * There is a new standard library available: kpse The most important function in that library is find_file: string = kpse.find_file(string filename [,string type] [,boolean mustexist]) both "type" and "mustexist" are optional, so the function has from one upto three arguments. "type" is like the '-format' argument of kpsewhich. You can run 'kpsewich -h' for a list. The default type is "tex". "mustexist" is like '-must-exist', and the default is false. If you specify "true" (or a nonzero integer), then the kpse library will search the disk as well as the ls-R databases The new library also has three other functions that map straight to kpsewhich commandline options: string = kpse.expand_path(string) string = kpse.expand_var(string) string = kpse.expand_braces(string) * There is a second callback possibility: texio.show_error_hook(string message, string|number indicator, number lineno) This command is run from inside the TeX error function, and the idea is to allow you to do some extra reporting on top of what TeX already does (none of the normal actions are removed). "message" is the formal error message tex has given to the user (the line after the "! ") "indicator" is either a filename (when it is a string) or a location indicator (a number) that can means lots of different things like a token list id or a \read number. "lineno" is the current line number This is an investigative item only, comments are welcome but do not take the syntax seriously. The final goal IMO is the total replacement of TeX's error handling routines, but that needs lots of adjustments in the web source because TeX deals with errors in a somewhat haphazard fashion (it needs unification first). The current hook is only for 'testing the water'. * It is now possible to use named items in the tex.count[] tex.dimen[] tex.toks[] subtables, so you can have tex.count.scratchcounter = 0 local enormous = tex.dimen["maxdimen"] Luatex looks up the value for you on the fly. You have to use a valid \countdef (or \dimendef, or \toksdef), anything else will generate an error. In a normal TeX file, you don't do \dimen\maxdimen, but the lua syntax seems to be a bit cleaner to me. The intention is to evntually also allow \chardefs and macros that expand into a number (todo) * The tex table has also been extended with a large list of internal parameters (partially read/write). It is possible to access about every primitive that you can use after \the *and* is a single token. So there is integer = tex.tracingcommands (\the\tracingcommands) integer = tex.prevgraf (\the\prevgraf) string = tex.output (\the\output) etc. for all of the internal parameters, but not the items that need extra arguments (like \the\scriptfont ) The subset comprising simple integer and dimension registers are writable as well as readable (stuff like \tracingcommands and \parindent). The fact that both lists are still quite limited is a result of the very different types of things that can occur after \the and also on the LHS of an assignment. The remaining primitives will be filled in when there is a real need or implementation becomes simple, whichever comes first. Have fun, Taco ------------------- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are two released files: * luatex-snapshot-20060908.tar.gz This is the source tree. * luatex-snapshot-20060908-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). This executable cannot run dynamically loaded lua dlls. Perhaps that can be fixed but I do not know how.
