Punctuation in pdf in Exercise titles

[nordstromjf]

I am using [] in exercise titles in my PreTeXt code as follows:

Similarly, determine the expected value for Player 1 for the pure strategy pair [B, F]. What is Player 2's expected value?

The HTML puts the period after the ] in the title and looks fine, but the pdf generated from the latex version has [B, F .] (space, period, ])

[rbeezer]

Ooh, that's bad. Likely the brackets are being confused with the end of an optional argument.

It should be fixed. But in your case, is "[B,F]" mathematics? Are you using an "m" tag? If not, is it better that way?

Maybe the title needs "protection" with curly braces, like I believe is happening with optional short titles already (migrating to the ToC).

The part should be in math mode, but there could be some case we did not think of yet that has regular square brackets.

The first instance I have this notation in a title, I would like it to say “Payoff for [Bet, Fold].” With the syntax I posted in the issue, the pdf says “Payoff for [Bet, Fold .]” The html is fine, and looks like I want. Here are some things I tried and what happened:

, of course the Bet and Fold are italicized in the html, but the big problem is I couldn’t tex it since when I ran pdflatex it got an error: missing $. [Bet,Fold], and [\text{Bet}, \text{Fold}], here the html still looks a little weird because the math font is different from the regular font, but again I get the missing $ error with pdflatex. I think it is the use of [] that is causing problems, since if I try Bet, Fold with no [ ], I don’t get an error. I already switched notation throughout the book since {Bet, Fold} had problems in the pdf (missing {}). So, basically the use of [] in math tags makes things worse in titles.

Thanks for the debugging. The use of [,] and {,} by LaTeX for grouping and arguments is almost certainly the root cause, along with titles moving around.

We've protected against this sort of thing befor - I've got an idea for a fix.

You could try the PTX elements, and (iirc)for now, as well. Not sure if they will behave better. They might.

Hi Rob,

The element works just like [ ]. I have updated both my html and my matching pdf on my git hub page. So if you are curious you can see how the pdf looks: https://nordstromjf.github.io/IntroGameTheoryv4.pdf

Section 2.4 has the first occurrence.

Again, the HTML looks just fine.

Thanks for the testing. I'll get it fixed. Very busy with other PTX work for two weeks. What is your timeline for a beautiful PDF?

No rush. I posted what I have. Unlikely that I will repost any time soon.

Thanks,

Similarly, determine the expected value for Player 1 for the pure strategy pair [B, F]. What is Player 2's expected value?

The HTML puts the period after the ] in the title and looks fine, but the pdf generated from the latex version has [B, F .] (space, period, ])

[rbeezer]

This should be fixed now. Thanks for your patience waiting for this. Testing with your examples would be appreciated.

Checkpoint 25.19 (or 25.20) of the sample article (which is now exposing an existing numbering bug).

Should fix about 10 of the similar blocks that are being styled via tcolorbox now. Fix at 46fa86197c8a685cfeb4520bf590613a2b91a218.

Rather than protecting optional arguments with groups (curly braces), I'd like to replace dangerous characters by safe equivalents, such as \textlbrace. But I can't seem to find one for square brackets.

[rbeezer]

And I should have also said: thanks for reporting this and testing the bad behavior.
