The very last macro

The very last macro

[luigi scarso]

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.

TIA

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
)

What do you expect?

'FOO' is text and invokes the OTR, if you don't say what do you
want to achieve there is no way to give you a answer.

hmm I always wrote

(what I expected is a pdf exactly like this
\starttext
hello
\stoptext
)

see
a few lines from the bottom of my second mail

Of course there is always a way to modify  bin/context ...and so on --
but I don't mean this .

What should I see?

And how could this help?

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

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

this text (quoted now)
"""

"""
It was  a few lines from the bottom of my second mail .

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 )

hmm

\def\LuigisWhateverShouldHappen{\immediate\write16{BOOOM!}Something
Luigi want to do for some unknown reason.\immediate\write16{BOOOM!}}

\let\luigissavednormalend\normalend

\def\normalend{\luigissavednormalend\LuigisWhateverShouldHappen}


\starttext
hello
\stoptext


Ok , I don't see "Something....reason." in pdf ,but ....
do you see BOOOM! in output or log ?

I don't -- so I can't say that \LuigisWhateverShouldHappen it's the
last macro before end run :( .

Your solution  looks like a macro or  text after \stoptext  -- we have
already seen it -- .



I start to suspect that this macro does  not exists .

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 :-)

true, but not so robust.

\def\LuigisWhateverShouldHappen{..what ever...}
\appendtoks\LuigisWhateverShouldHappen \to \everylastshipout
\starttext
hello
\stoptext

I want  be sure that
"..what ever.."
will never introduce differences with

\startext
my stuffs here
\stoptext

for *ever* "my stuff here" and for *ever*  "..what ever.."

I  believe that it's no possible.

Anyway
\def\LuigisWhateverShouldHappen{..what ever...}
\appendtoks\LuigisWhateverShouldHappen \to \everylastshipout
\starttext
hello

can be good enought .

why, what do you want to achieve; there are already such hooks

> 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.''

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

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)

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

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

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.

{*******************************************}
end_of_TEX: close_files_and_terminate;
final_end: ready_already:=0;
end.

=======================================


anyway,  as I wrote , this is not bad:

\def\LuigisWhateverShouldHappen{\immediate\write16{BOOOM!}Something
Luigi want to do for some unknown reason.\immediate\write16{BOOOM!}}

\appendtoks\LuigisWhateverShouldHappen \to \everylastshipout
\starttext
hello
\stoptext

\LuigisWhateverShouldHappen
can be made more robust -- for example you can find a way to nullify
"Something...reason." so it doesn't appear on final pdf , and so on --

For example, this looks a bit better -- no
Something Luigi want to do for some unknown reason.

\def\LuigisWhateverShouldHappen{%
\vbox to 0pt{\vss\hbox to 0pt{\hss \immediate\write16{BOOOM!}Something Luigi
want to do for some unknown reason.
\immediate\write16{BOOOM!}}}}
