How to make a key to on, off solutions of exercises in `answers` package? 7

Anonymous 1123 Anonymous 1123

11 You can add your own if statement to switch on/off the solutions. In the following example, they will be off by default. Use `\solutionstrue` to switch them on or `\solutionsfalse` for off again.

mirabilos replying to Skillmon

yeah, I was in a maximum hurry (had to finish something that night which I only knew on the day itself); if I have time, I can do proper questions with MWE  
  
the wrapfig was directly after `\begin{document}`, but it didn’t specify a number of lines; I figured that would be okay because the normal body lines that went far enough to the right (quite a ways below it, too) were ok, but a few pages later the section headings were still too narrow

Skillmon

@mirabilos if you need help with something I suggest you create a minimal example and ask a proper question. That aside: Your `wrapfig` was probably used inside a group or something, it's known that it breaks following paragraphs if used incorrectly.

mirabilos

phew, got it to work (a similar `after` was needed), I’m **so** done with this now

mirabilos

… and of course, now I see cells/rows aren’t broken *anyway*, but still getting rid of the minipage is technically better, maybe…

mirabilos

ah it DOES work in `before=` in setlist, but it does need the extra `\baselineskip`

mirabilos

`\vspace{-\parskip-\baselineskip}` does seem to do the trick, but not in `\setlist`…

mirabilos

of course not even `\@minipagetrue` will remove the space…

mirabilos

minipages around work but aren’t breakable, and adding a tcolorbox around THEM gives me an error the first time one would be broken, so meh

mirabilos

gah, I run into the best things… `\setlist[itemize]{before=\vspace{-\parskip},topsep=0pt,partopsep=0pt,leftmargin=*,after=\strut,itemsep=0.5ex}%` fails to remove the vertical space before a list inside a table cell (as does `topsep=-\parskip`) and on SE everyone says this works for them…

mirabilos

I probably should just set the picture into the page background, it doesn’t even overlap with text when not wrapping…

mirabilos

aaaaaaaah it’s from a wrapfigure MUCH further atop

mirabilos

in both `subsection*` and `subsubsection*`

mirabilos

but without that they are cut off as well

mirabilos

hmm it does use `[bf,sf]{titlesec}`

mirabilos

not twocolumn

mirabilos

hmmmm, why would a subsection not span the entire page width in a twoside article?

Skillmon replying to mirabilos

As others have mentioned, most just works out of the box in both engines. Just don't load `fontenc` nor `inputenc` (which you don't need to load nowadays as long as you're using UTF8 file encoding since that's the default in LaTeX). All the other major packages just work™ and you even get a select few great packages that only work in LuaTeX (`lua-ul` is by far the best underlining package for instance, and there is `chickenize`).

Ulrike Fischer replying to mirabilos

I know the list of issues, see https://github.com/tabu-issues-for-future-maintainer/tabu/issues. And I can promise you that at least we (the latex team) will not fix them. I looked long enough into the code to know that it is hopeless. And I also know the changes we made in the past time to the tabular code, and tabu will not like that.  And I normally do not use tabularray, but the normal tabular, which works fine and is fast.

mirabilos replying to Ulrike Fischer

funny, it’s not broken for me, whereas the supposed replacement completely breaks being able to build within reasonable timeframes  
  
no, you’ll pry `tabu` from my cold dead fingers ;-)

Ulrike Fischer replying to mirabilos

you should not use tabu. It was already broken in 2020 and it will not get better.

mirabilos

but at least a basic font test seems to work (cannot check all details, but I got the european a/g at least)

mirabilos

and no info which ligatures (other than TeX) are on by default…

mirabilos

it’s also vague wrt. what is the default (Kerning=On seems to be)

mirabilos

maybe `CharacterVariant={37,47,68,69,77,79}` and ignore the `:n`?

mirabilos

CharacterVariant takes two values, but all I know is I have to enable cv37 cv47 cv68 cv69 cv77 and cv79

mirabilos

okaaay, so, the fontspec doc is giving me trouble

samcarter replying to mirabilos

You probably don't need inputenc - I think utf8 is used as default since 2018 or 19?

mirabilos replying to samcarter

ok, trying… I’m putting the inputenc/fontenc behind `\ifluatex` to have a fallback

samcarter replying to mirabilos

In case you load `fontenc` in your document, you might want to remove it when switching to lualatex. With an up-to-date lualatex, that should be all that's necessary for most document.   
  
However with such an old lualatex, some packages might need additional options.

निरंजन replying to mirabilos

There should be no problem with `tabu`.

mirabilos

(and I very much prefer to stick to the older version because the chance of having `tabu` working are higher there)

mirabilos

ok, thanks! will ask back should I run into things

निरंजन

So to answer "how do I even start?", just change the engine and try out `fontspec`. Mostly things should be fine.

निरंजन replying to mirabilos

This should work, all the PDFLaTeX code should _just work fine_. But if there is any problem, you have a specific question... ;-)

mirabilos

not gotten far enough

mirabilos

I don’t have specific questions yet ;-)

mirabilos

thanks; I was looking for a general “how do I even start” (beginning with “so I just run lualatex instead of pdflatex 2‥3 times, same parameters or lack thereof), the setmainfont command for example (that’s fontspec?)

निरंजन replying to mirabilos

Mostly your `pdflatex` code should work with `lualatex` too, but a recent and a full installation is recommended. You may try experimenting with the `fontspec` package which enables OpenType support in `lualatex`, but a specific question would help a lot. Typically, for loading an OpenType font (with a stylistic set) as the "main" font of the document, the following setup should work:  
  
```  
\documentclass{article}  
\usepackage{fontspec}  
\setmainfont{fontspec}  
\setmainfont[StylisticSet={5}]{NewCM10-Book.otf}  
```

mirabilos

from the 13 year old questions on SE it appears I mostly can use the same things as before except I have to read the fontspec manual first?

mirabilos

my reference system is Debian bullseye, so `texlive-latex-recommended (2020.20210202-3)`

mirabilos

hi… about to try lualatex for the first time… is there a quick migration guide for people used to pdflatex? (mostly I want opentype stylistic sets, that’s why…)

Oh, rabbit-powered packages!

Also, @Skillmon congratulations!

निरंजन replying to samcarter

I will also try it. :)

samcarter replying to निरंजन

I've done it last week: got 20 GB back and it seems to work without problems so far.

निरंजन replying to samcarter

So interesting!!

meanwhile, this blog post was recently mentioned on the mailing list of the German tex user group:

This might be interesting for everyone who collects old texlive versions.
