lmtx update

lmtx update

[Hans Hagen]

Hi,

Sorry for the long mail ...

One of the changes in lmtx is that we freeze the properties that 
determine the paragraph shape as well as breaking into lines in such a 
way that we have predictable behaviour. As a side effect it can be that 
existing code (lmtx only) will behave differently (will be fixed when we 
notice) but also that some low level user tweaking can not work, i.e. 
they are just ignored, but only when they happen mid paragraph which 
actually is always debatable anyway.

Now, if for some reasom you get unexpected results and can't wait for a 
fix, you can do this:

   \forgetparagraphfreezing : disables
   \setparagraphfreezing    : enables (default)

Of course it might have other side effects once in lmtx we everywhere 
expect freezing to be enabled. You can take a snapshot with:

   \freezeparagraphproperties  : snapshot relevant parameters
   \defrostparagraphproperties : resets snapshot

More efficient is snapshotting a subcategory:

   \updateparagraphproperties : all
   \updateparagraphpenalties  : only penalties
   \updateparagraphdemerits   : other than penalties
   \updateparagraphshapes     : hangindent etc

Don't use the low level commands that they use because we take plenty of 
time to experiment at that level and interfaces might evolve, for instance:

\frozen\hangindent 30pt
\frozen\hangafter  2

is valid and will likely stay.

We're talking of a conceptually rather different approach. Internally 
the engine is still doing the same things but we can control it a bit 
differently. Due to the way ConTeXt is set up, we can make such a 
paradigm shift without too much troubles. I'll wrap up more details in 
an article later.

Other work in progress is: better columns in itemize, esp proper 
footnote support (not that I ever need that but I know users do so ...), 
experiments work ok, but I need to check spacing. In general, footnotes 
(will) behave a bit better, especially those used nested in other 
mechanisms. A side effect of more control is that we can do other tricks 
too and we're playing with it (kind of fun).

More work in progress concerns paragraph wrappers and that will result 
in a rewrite of some existing mechanism (generic subsystems with 
instances), but that might as well go unnoticed.

To give an idea of possibilities, here is an example:

\definedescription[whatever][alternative=right:bottom]

\startwhatever{just a small\\example}
     \input ward
\stopwhatever

No one ever requested it so see it an a quick and dirty example but 
don't hesitate to ask for more anyway (we like an occasional challenge).

Anyway, it might take some weeks / iterations before all this settles 
down and now you can't say that we didn't warn you.

So far,

Hans

Are those global or local or can they be prefixed? For example, can we do this:

  \setparagraphfreezing
  ….
  \placefigure[left]{}{} {Bla bla \forgetparagraphfreezing .. <override some stuff> }

or would that still trigger the built-in freeze ?

the forget will basically tell the system that it should use the normal 
(register) variables ... a freeze stores values in the local par node 
but also stores which parameters are stored, so it is selective (one can 
  freeze specific ones

\snapshotpar \frozenhangaftercode

which now makes me think: i can let a negative value do a specific 
unfreeze (\snapshotpar0 will unfreeze all)

> or would that still trigger the built-in freeze ?

the (enabled by default) stored the values right after the par has started

\setparagraphfreezing

so then these values are frozen

a successive change is then not used, but say that you do

\parfillskip100pt

in the middle of a paragraph, then that one will affect the next paragraph

\bgroup
\frozen \parfillskip100pt
\egroup

when this is done inside a paragraph, the assignment is done local, then 
it gets frozen in the current paragraph but it will not affect the next 
paragraph unless of course you used \global

(\frozen is just a prefix and when it's time to do an assignment, just 
like the global state is checked, the frozen state is checked, and 
applied after the normal assignment, of course only for variables that 
deal with the par buildingl it is ignored otherwise; so, \frozen also 
works here: \frozen\advance\leftskip 10pt\relax)

Hi Hans,

Thanks for your explanations.

Regarding footnotes, would it be possible to have a built-in support for writing the footnotes in the margin? (For instance, assuming that the layout is such that for instance the right margin takes 1/3 of the page width, then the footnotes would occupy the right margin, beginning at the top).

Best regards: Otared

It depends on what you want. This works ok:

\setuplayout
   [cutspace=5cm,
    width=middle,
    margin=4cm]

\setuptexttexts
   [margin]
   [] [{\directsetup{notabene}}]

\startsetups notabene
     \vbox to \textheight \bgroup
         \setupalign[tolerant]
         \topskipcorrection
         \placenotes[endnote][before=,after=]
         \vfilll
     \egroup
\stopsetups

\starttext

test \endnote{\input ward }\par
test \endnote{x}\par
test \endnote{x}\par

\setups{notaflush}

\stoptext

This one handles overflow (suboptimal, nicer is stepwise flushing) but 
this one also flushes notes that have refs on the next page. It just 
indicates the usual: most can be done in tex without too much hassle but 
one always needs to think about the edge cases as users can drop 
anything in there and all can interfere.

\newbox\MyNoteOverflow

\startsetups notabene
      \setbox\scratchbox\vbox\bgroup
         \setupalign[tolerant]
         \ifvoid\MyNoteOverflow \else
             \unvbox\MyNoteOverflow
         \fi
         \placenotes[endnote][before=,after=]
     \egroup
     \scratchdimen\dimexpr\textheight-.5\lineheight\relax
     \ifdim\ht\scratchbox>\scratchdimen
         \global\setbox\MyNoteOverflow\box\scratchbox
         \setbox\scratchbox\vsplit \MyNoteOverflow to \scratchdimen
     \fi
     \vbox\bgroup
         \topskipcorrection
         \unvbox\scratchbox
         \vfilll
     \egroup
\stopsetups

\startsetups notaflush
     \doloop {
         \page
         \ifvoid\MyNoteOverflow
            \exitloop
         \else
            \null \page
         \fi
     }
\stopsetups

\starttext

test \endnote{\input ward }\par
test \endnote{x}\par
test \endnote{x}\par

\setups{notaflush}

\stoptext

Variants (i can make one but not with this warm weather) can use 
selective flushing (all kinds of things are possible with notes) but 
another challenge is to have an independent criterium hooked into the 
page builder (when i'm done with playing with extensions regarding pars 
i might give that a go ... as usual more a challenge than a need so i 
need some motive).

Hi Hans,

That's great! Thanks a lot!
I have two questions in order to adapt what you sent to my case.
I played a bit with your second solution, as in:

%%%%%%% begin sidenote-Hans.tex
\showframe
\setupinteraction[state=start]
\setuplayout
	[cutspace=7cm,
	width=middle,
	margin=5cm,
	margindistance=7mm]

\setuptexttexts
	[margin]
	[] [{\directsetup{notabene}}]

\newbox\MyNoteOverflow
\setupnotation[endnote]
	[interaction=yes,
	after={\blank[big]}]
	
\startsetups notabene
	\setbox\scratchbox\vbox
	\bgroup
		\setupalign[tolerant]
		\ifvoid\MyNoteOverflow 
		\else
			\unvbox\MyNoteOverflow
		\fi
		\placenotes[endnote][before=,after=]
	\egroup
	\scratchdimen\dimexpr\textheight-.5\lineheight\relax
	\ifdim\ht\scratchbox>\scratchdimen
		\global\setbox\MyNoteOverflow\box\scratchbox
		\setbox\scratchbox\vsplit \MyNoteOverflow to \scratchdimen
	\fi
	\vbox
	\bgroup
		\topskipcorrection
		\unvbox\scratchbox
		\vfilll
	\egroup
\stopsetups

\startsetups notaflush
	\doloop {
	\page
	\ifvoid\MyNoteOverflow
		\exitloop
	\else
		\null \page
	\fi
	}
\stopsetups

\starttext

\dorecurse{10}{
	test \endnote{\input ward }\input tufte.tex \par
	test \endnote{This is a note about Ward, who says: \par \input ward.tex} \input ward.tex \par
	test \endnote{This is a note about Donald Knuth.} \input knuth.tex \par
	}
This is a last note. \endnote{This last note is here to see what happens in the next page\dots\par \input knuth.tex}
\par \input knuth.tex
%\setups{notaflush}
\stoptext
%%%%%%% end sidenote-Hans.tex

The first question is why did you define a setups called notaflush, and why your example works fine without using it ?

The second question is: the side notes are vertically centered in the margin (one can see this when the notes do not cover all the margin), which is fine for me. But, out of curiosity, what can be changed in the setups notabene in order to have the notes to begin at the top of the margin ?
(When a note runs into the next page, as in the last note, then it would be nicer to begin on top of the margin).

Thanks again: Otared K.

I wanted to have footnotes in the margin, possibly starting in the same line as the marker.

Wolfgang came up with this:

Hi Hraban,

Thank you for reminding me of the solution cooked up by Wolfgang for you a few years ago. That solution works fine when the notes are short enough, but in some cases the notes in the margin bump into each other (indeed it is not a good habit to have long notes, but in some cases one cannot avoid them).

Best regards: Otared

That solution works fine when the notes are short enough, but in some cases the notes in the margin bump into each other (indeed it is not a good habit to have long notes, but in some cases one cannot avoid them).

One essential bit is missing in the wiki example:

\setupmargindata[inmargin][
  location=right,
  stack=continue, % !!
  align=flushright,
]

The code I’m actually using for our German literature magazine “Kritische Ausgabe” is much more elaborated, but also cluttered with obsolete stuff – I need to sort that out some time...
(I only deleted some styling.)

%%% Footnotes / Marginals

\setupmargindata[inmargin][
  location=right,
  stack=continue,
  align=flushright,
]
\setupmargindata[inouter][
  location=right,
  stack=continue,
  align=flushright,
]

\def\FNVOffset{0} % Negative vertical offset of footnotes in lines
% Manual tweaking was necessary for a while, when stacking didn’t work reliably.

\def\MarginNote#1{%
\inmargin[
  voffset=\dimexpr-\FNVOffset\lineheight\relax,
  width=\ColWidth,
  align=flushleft,
]{%
  \inframed[
    width=\ColWidth,
    align=right,
    frame=off,
    offset=overlay,
    strut=yes,
    ]{#1}%
  }%
}

\define\PlaceFootnote{%
\inmargin[
  voffset=\dimexpr-\FNVOffset\lineheight\relax,
  width=\ColWidth,
]{%
  \vtop{\placelocalnotes[footnote][before=,after=]}}%
}

\def\FNo#1{{#1~}}
% I never managed to get number and text in consecutive lines without indented text
% or at least a constant whitespace after the number.

\setupnote[footnote][
  location=text,
  bodyfont=,
  indenting=no,
  before={\noindentation},
  next=\PlaceFootnote,
]

\setupnotation[footnote][
	way=bychapter,
	align=flushleft,
  indenting=no,
  location=serried,
  alternative=serried,
  width=broad,
  numbercommand=\FNo,
] % footnote text

\setuptexttexts[margin][][%
  {\framed[
    align={flushright,bottom},
    frame=off,
    height=\textheight,
    width=\ColWidth,
  ]{%
    \strut\vfill\placenotes[footnote]}}%
]


Best, Hraban

Re: margin notes (was: lmtx update)

[Otared Kavian]

Hi Hraban,

Thank you for taking the time to send your code for sidenotes.
Unfortunately when I add

\starttext
test\footnote{A footnote in the margin.}
\stoptext

to your code, I get an error and unfortunately with recent versions of LMTX the error message 
!  Undefined control sequence
is not helpful to find the error… (LMTX considers \footnote as an undefined control sequence…).

Best regards: Otared

That solution works fine when the notes are short enough, but in some cases the notes in the margin bump into each other (indeed it is not a good habit to have long notes, but in some cases one cannot avoid them).

Of course it’s not \footnote that is undefined but something else from my code – I didn’t take the time to strip it of all the references to other setups in the same environment, probably \ColWidth that was just a shortcut for the column width:
\def\ColWidth{57mm}

Re: margin notes (was: lmtx update)

[Otared Kavian]

Hi Hraban,

Thanks for the hint… indeed I did see that \ColWidth command but didn't think about its definition… Sorry!

Now with \ColWidth defined, your code works fine and it has the advantage that the text of the sidenote begins in the margin at the level where the \footnote command appears. However, it cannot control the overflow of a sidenote to the next page, whereas the code given by Hans can do that. I admit that this does not happen very often since a well designed text should not have too many long sidenotes…

In case other users would like to use your code, I put the whole example below.

Best regards: Otared
%%% sidenotes, or footnotes in the margin
%%% example given by Hraban:
%%% here the tweaking of the width of the sidenote is turned off
%%% remove the comment where there is \ColWidth
%%% in order to adapt to your layout

	width=middle,
	margin=5cm,
	margindistance=7mm]

\setupmargindata[inmargin]
	[location=right,
	stack=continue,
	align=flushright,
	]

\setupmargindata[inouter]
	[location=right,
	stack=continue,
	align=flushright,
	]

\def\FNVOffset{0} % Negative vertical offset of footnotes in lines
% Manual tweaking was necessary for a while, when stacking didn’t work reliably.

\def\MarginNote#1{%
	\inmargin[
		voffset=\dimexpr-\FNVOffset\lineheight\relax,
%		width=\ColWidth,
		align=flushleft,
		]{%
			\inframed[
%				width=\ColWidth,
				align=right,
				frame=off,
				offset=overlay,
				strut=yes,
			]{#1}%
		}%
	}

\define\PlaceFootnote{%
	\inmargin[
		voffset=\dimexpr-\FNVOffset\lineheight\relax,
%		width=\ColWidth,
	]{%
	\vtop{\placelocalnotes[footnote][before=,after=]}}%
	}



\def\FNo#1{{#1~}}
% I never managed to get number and text in consecutive lines without indented text
% or at least a constant whitespace after the number.


\setupnote[footnote]

Does this mean we can get two-column footnotes in two-column documents?

Hi Hans,

many thanks for your explanation.

I wonder whether the new improvements could prevent body text running
into the footnotes (as some of us have already reported).

> don't hesitate to ask for more anyway (we like an occasional challenge).

If you are open for suggestions, I would ask for a footnotes that behave
as a page index, such as in:

  \setuplanguage[en][patterns={en,agr}]
  \setuppapersize[A6]
  \setupbodyfont[dejavu]
  \definenote[dict]
  \setupnote[dict][n=2,rule=off,
      split=strict, inbetween=\hskip1.5em]
  \setupnotation[dict][number=no,
      style={\tfx\setupinterlinespace[line=2.5ex]}]
  \starttext
  Πρῶτον δεῖ θέσθαι τί ὄνομα\dict{ὄνομα,
  -ατος, τό: noun} καὶ τί ῥῆμα\dict{ῥῆμα, -ατος, τό: verb},
  ἔπειτα τί ἐστιν
  ἀπόφασις\dict{ἀπόφασις, -εως, ἡ: negation}
  καὶ κατάφασις\dict{κατάφασις, εως, ἡ:
  affirmation} καὶ ἀπόφανσις\dict{ἀπόφανσις,
  -εως, ἡ: statement} καὶ λόγος.
  \stoptext

What I need there is that these notes are alphabetically sorted, such as
in a standard register.

As I proposed that (years ago), you told me it was too complex. I wonder
whether this would be easier with the current developments.

Many thanks for your improvements to ConTeXt,

Pablo
