sorry for the noise : is there in mkiv a very last macro ? I mean something like \IamCallAtTheReallyEnd{..} which does absolutly nothing to the pdf , and  after  which mkiv ends without calls any other macro.

\normalend?

hm \def\normalend{FOO} \starttext hello \stoptext stops with * while \def\normalend{FOO\end} \starttext hello \stoptext has an endless loop . (what I expected is a pdf exactly like this \starttext hello \stoptext ) -- luigi

What do you expect?

'FOO' is text and invokes the OTR,

true

What should I see?

this text (quoted now) """ (what I expected is a pdf exactly like this \starttext hello \stoptext ) """ It was a few lines from the bottom of my second mail .

If you don't want text in your output write it after \stoptext.

\starttext Text in the PDF. \stoptext Ignored text.

no : \starttext Text in the PDF. \stoptext \AlsoIgnoredMacro \AlsoIgnoredMacro is ignored ie it's no called . Let's start again: suppose that \appendtoks\LuigisWhateverShouldHappen\to\everybye works So between \def\LuigisWhateverShouldHappen{FOO} \appendtoks\LuigisWhateverShouldHappen\to\everybye \starttext hello \stoptext and this \starttext hello \stoptext must be no differences at all. And also between \def\LuigisWhateverShouldHappen{..what ever macro I like to write here ..} \appendtoks\LuigisWhateverShouldHappen\to\everybye \starttext hello \stoptext and this \starttext hello \stoptext must be no differences at all. But in both situations I want to be sure that \LuigisWhateverShouldHappen will be the last macro called . I'm not saying that this macro exists; (of course one can manipulate /bin/context (or others scripts) even rewrite \stoptext ) -- luigi

You said that you wanted \LuigisWhateverShouldHappen macro to be executed, which in turn means that \immediate\write18 is executed, the text Something .... reason is written to the pdf, and the macro \imediate\write18 is executed. If you do not want the text to be written to the pdf, do not add it to \LuigisWhat... macro :-) Aditya

why, what do you want to achieve; there are already such hooks The original request was sorry for the noise : is there in mkiv a very last macro ? I mean something like \IamCallAtTheReallyEnd{..} which does absolutly nothing to the pdf , and after which mkiv ends without calls any other macro

Peter suggest to use \everylastshipout; but this \def\LuigisWhateverShouldHappen{\immediate\write16{BOOOM!}Something Luigi want to do for some unknown reason.\immediate\write16{BOOOM!}} \appendtoks\LuigisWhateverShouldHappen \to \everylastshipout \starttext hello \stoptext write Something Luigi want to do for some unknown reason. near the bottom of pdf (and I don't want it) and BOOM! on log (which is a way to say that this macro was called) Aditya suggests to put nothing to print in \LuigisWhateverShouldHappen and I said that it's no a robust solution . BTW, for a specific document, this is actually a solution -- just need a bit of test -- I'm almost sure that there is no solutions much differents from this one.

From luatex.web , around line 22423 :

@ We don't want to leave |main_control| immediately when a |stop| command is sensed, because it may be necessary to invoke an \.{\\output} routine several times before things really grind to a halt. (The output routine might even say `\.{\\gdef\\end\{...\}}', to prolong the life of the job.) Therefore |its_all_over| is |true| only when the current page and contribution list are empty, and when the last output was not a ``dead cycle.'' -- luigi

the problem is in your definition of 'end' and 'bottom'

?? end := end of run bottom := bottom of last page, in this case

the real final thing is \end and \everygoodbye happens just before that (the only calls after it are postponed error messages, which have no consequence for any pdf and the primitive \end which is really needed)

yes, as I seen in \def\stoptext

of course there can be pending conditional branches that needs to be finished; just try \appendtoks\tracingall\to\everygoodbye

true

You can also do something

\startluacode table.insert(input.stop_actions, function() texio.write_nl("I still have no clue why you need it.") end) \stopluacode

ok thank you -- I like lua code --

any other hook in itself will introduce a new situation of 'something done before the real \end'

exactly what I mean: "any other hook in itself will introduce a new situation of 'something done before the real \end'" that potentially can modify current page . Consider this: between final_cleanup; {prepare for death} and end_of_TEX: close_files_and_terminate; insert {************* MY HACK ************} almost_death ;{I see state, but it's 'frozen' so any modification will never influence pdf or dvi , only to log or terminal or external files} {*******************************************} in almost_death you can do what ever you want -- you will never modify (relevant part of ) state that can influence final pdf or dvi . ================================================== @ Now this is really it: \TeX\ starts and ends here.
