Memoize produces an extern over and over again when used with the todo package

[atticus-sullivan]

Hi,

I quite frequently use the todo latex package when writing documents. Now when inserting a \Todo in e.g. a tikzpicture (which is memoized) I get some strange behavior and the extern for that image is produced over and over again. But see for yourself:
Note that I'm using two tikzpictures, one using a simple \ref (for reference) and one using the \Todo. Also note the comments I inserted in the (shortened) output below.

# turns out, no still the same extern is being generated.

I have to admit, I'm not that familiar with the cross-referencing part but I think since \Todo uses \ref internally, it should work out of the box, shouldn't it?

So there may be one or two issues here:

• Using the todo package does not work. But ok, todo is not aware of memoize and so I'd need to configure this manually, so maybe no real problem at all (still, I thought it would work automatically due to the usage of \ref internally). Of course in the case I'd be interested in how one would make \Todo/\todo work. As far as i read the examples regarding the ref key, they all refer to commands which have the label they are refering to as argument.
• The output in the log states the file does not exist, but it indeed does exist (and is well-formed). Any idea where this might come from?

[sasozivanovic]

Sorry, I'm a bit swamped here, but I'll try to look into it asap.

[cfr42]

In general, memoize doesn't automatically treat a command which uses \ref as if it were itself a case of \ref, so I don't believe it's correct that memoize should handle \Todo automatically. For example, it doesn't treat \cref or \fref as like \ref unless told to do so. Of course, it doesn't keep recreating externs in those cases either - rather the opposite, in fact.

Running the MWE produces this, which seems somewhat weird:

\mmzUsedCMemo {memos/3E9506E82B16BC2B8D51514961456FDF.memo}
\mmzNewCMemo {memos/3E9506E82B16BC2B8D51514961456FDF.memo}

I thought it identified the memos by the hashes in their names, but I guess that was naïve.

\todo, \todo* and \Todo are more complicated than \ref, it seems to me because they don't (just) point somewhere else in the document. They are also pointed at from the list of to-dos. So consider,

\documentclass{scrartcl} % wouldn't article do?
\usepackage{todo}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
  \node {\ref{myLabel}};
\end{tikzpicture}

\begin{tikzpicture}
  \node [green,draw] {\Todo{missing green}};
\end{tikzpicture}
\begin{tikzpicture}
  \node [blue,draw] {\todo{missing blue}};
\end{tikzpicture}
\begin{tikzpicture}
  \node [red,draw] {\todo*{missing red}};
\end{tikzpicture}
\section{mySection} \label{myLabel}

xyz

\todos
\end{document}

which produces the following .aux:

\relax
\providecommand*\new@tpo@label[2]{}
\newlabel{todopage:1}{{1}{1}{}{}{}}
\newlabel{todopage:2}{{2}{1}{}{}{}}
\newlabel{todopage:3}{{3}{1}{}{}{}}
\@writefile{toc}{\contentsline {section}{\numberline {1}mySection}{1}{}\protected@file@percent }
\newlabel{myLabel}{{1}{1}{mySection}{}{}}
\newlabel{todolbl:1}{{1}{2}{mySection}{}{}}
\newlabel{todolbl:2}{{2}{2}{mySection}{}{}}
\newlabel{todolbl:3}{{3}{2}{mySection}{}{}}
\gdef \@abspage@last{2}

But you don't really need to worry about the references to the list of to-dos. Because you're not using hyperref (and, if you were, memoize would break the links anyhow) and the default format, at least, only displays the counter, which is determined when the to-do is inserted rather than when the item in the to-dos is written.

For the basic case, what matters is that the picture be regenerated if the value of \thetodo changes. But there are two complications.

One is that in the case of both \todo and \Todo, memoize seems not to recognise the hashes match (or something).

The other is the \todo* case, which causes the opposite problem, because the to-do simply disappears. This issue can be avoided with replicate, I think.

So I don't think treating these as cross-refs is obviously the right strategy here. Something more similar to label?

[atticus-sullivan]

First of all sorry for the long delay from my side.

Hm, ok I see.

Because you're not using hyperref (and, if you were, memoize would break the links anyhow)

Well in the end I am, it was just not necessary for the mwe. But I also thought, memoize would keep the links due to the .memo files.

But well for now I think the solution for me is to simply skip the memoization of those "pictures" (at some point in time the todo should be resolved after all and I personally delete the todo so then I can enable memoization again).

I'd just keep this issue open to track this and to close it when/if this is really resolved (especially the weird thing that memoize doesn't seem to recognize the already present extern)

[sasozivanovic]

Sorry for an even longer delay here. Here's what I cooked up — to be pasted into the preamble.

\makeatletter
\mmzset{
  include context in ccmemo,
  at begin memoization={\gdef\mmz@@todo@n{0}},
  auto/todo/.style={
    run if memoizing,
    args=som,
    collector options={return=plain},
    inner handler=\mmz@@todo,
  },
  auto=\todo{todo},
  auto=\Todo{todo},
}
\NewDocumentCommand\mmz@@todo{s O{\todomark} m}{%
  \xdef\mmz@@todo@n{\the\numexpr\mmz@@todo@n+1}%
  \gtoksapp\mmzContextExtra{%
    todo={\the\numexpr\value{todo}\ifmemoizing-\mmz@@todo@n\fi},
  }%
  \xtoksapp\mmzCCMemo{%
    \if@todo\else\noexpand\done\fi
    \unexpanded{\todo*[#2]{#3}}%
  }%
  \expandafter\AdviceOriginal\the\collargsArgs
}
\makeatother

This problem had several components. One was that Memoize's \ref support, in particular macro \mmzForceNoRef, did not pre-expand the cross-reference key. \todo executes \ref{todolbl:\thetodo}, but the value of \thetodo is of course not fixed. In particular, without any tweaking, it refers to the final todo before the memoized code when attempting to load the cc-memo, and to the final todo inside the memoized code after memoization, when cc-memo is created. Not good at all. Fixed in cbca67a, but here's also a patch (to be pasted into the preamble) if you want to test without pulling:

\def\mmzForceNoRef#1{%
  \mmz@Cos
  \expandafter\mmz@mtoc@csname\expandafter{\expanded{r@#1}}%
  \ignorespaces
}

Second, even fixing this was not enough (in fact, I only noticed this once I fixed other stuff, which I describe now). Cross-references introduced by \todo are unusual in that the cross-reference key is computed automatically. In effect, the first todo note will always have cross-reference key todolbl:1 with value (1) etc. Therefore, changing the order of two todo notes changes nothing (as long as they occur on the same page); consequently, if one of these todo notes appears inside memoized code, this code is not recompiled.

To address this issue, I have stored the memozation-initial value of counter todo into the context. Achieving this is somewhat involved. It needs a counter of todo notes inside the memoized code, reset at the beginning of every memoization and advanced at each \todo. At the end of the memoization, when the cc-memo is created, the final value of this counter is then substracted from the value of todo, to get to the same number that this latter counter will have once we try to load the cc-memo in the next compilation.

Third, \todo stores all the todo text in a register, which is then used to print out the list of todos. Even a memoized todo note must therefore still append to this register. Therefore, the auto-handler of \todo also "replicates" the \todo call in the cc-memo, but with the silent \todo* instead of the original todo command. The replication also takes \done into account.

The code works for \todo and \Todo, and accepts the star and the optional argument. I have not developed a handler for todoenv.

Please test and report.

still doesn't seem to be stopping at some point. Or is my setup somehow wrong? Do you get other behavior?

[sasozivanovic]

Sorry, I hadn't updated the prerelease to the current state of the repo. Done now, please download the zip file again.

[atticus-sullivan]

Alright. I'm not gonna pretend to understand what happens here but it works now. I'll also add a note to the wiki page referencing this issue.

Thank you 👍 (and don't worry about any delays, it's not work it's free time and it should feel like that).

---

One note unrelated to this issue: When I try to compile with lualatex (instead of pdflatex, I get: Undefined control sequence. <argument> \pdfpageattr{/Rotate 0} (only in the second run for my example)

[sasozivanovic]

Alright. I'm not gonna pretend to understand what happens here but it works now.

This one was pretty involved, indeed. I guess I'll have trouble understanding it in a week as well ;-)

I'll also add a note to the wiki page referencing this issue.

Thanks!

One note unrelated to this issue: When I try to compile with lualatex (instead of pdflatex, I get: Undefined control sequence. \pdfpageattr{/Rotate 0} (only in the second run for my example)

And thanks again. LuaTeX needs \pdfpageattr -->\pdfvariable pageattr, but I forgot to do this.
