Today I update my MikTeX installation. Among updated packages is l3kernel which doesn't work with calligraphy library, even if it is not used in TikZ picture:

\documentclass[border=1mm, tikz]{standalone}
\usetikzlibrary{decorations.pathreplacing,%
                    calligraphy
                }
\begin{document}
    \begin{tikzpicture}
\draw[->] (0,0) --(3,0) node [right] {$t$};
    \end{tikzpicture}
\end{document}

which gives error:

! LaTeX3 Error: Variant form 'nnV' deprecated for base form '\spath_get:nnN'.
(LaTeX3)        One should not change an argument from type 'N' to type 'V':
(LaTeX3)        base form only accepts a single token argument.

Type <return> to continue.

After abandoning of compilation editor open file spath3.sty and indicate that error has source in line 197:

\cs_generate_variant:Nn \spath_get:nnN {nnV,VnN,VnV}

Since I frequently use the calligraphy I stuck with my temporary LaTeX project. It had problem with l3... packages before, but it had been managed with temporary fix provided in Joseph Wright answer: 

\usepackage{expl3}
\ExplSyntaxOn
\int_zero_new:N \g__prg_map_int
\ExplSyntaxOff

but this temporary fix is not sufficient anymore :-(.

addendum: meanwhile i had private correspondence wit author of the package spath3 and tikz libraries calligraphy and knots (among others). I had privilege to test new version of the package and libraries. The tests has been successful, so we can expect that new version of spath3 bundle (package, libraries) will be on the way to CTAN soon.

Thank you to all who with their comments help me, special thanks is going to Andrew Stacey, the authors of the package and libraries, who respond so quickly and provide new version of package and libraries.

  • A single “illegal” variant is used in \SPathInfoInto. The package spath3 should be updated in order to fix this; by the way, the definition of \SPathInfoInto is flawed anyway. And the \spath_get:nnV variant is meaningless. – egreg Jan 05 '19 at 22:31
  • Add to your fix \RenewDocumentCommand{\SPathInfoInto}{mmm}{\spath_get:nnN{#1}{#2}#3}. In order to remove the warnings, there's nothing else to do than waiting for an update. By the way, I get warnings and not errors. – egreg Jan 05 '19 at 22:40
  • @egreg I get a warning in texlive but an error in miktex - and in miktex expl3 is newer (2019-01-01) then in texlive (2018-12-12 L3). That's rather odd. – Ulrike Fischer Jan 05 '19 at 23:48
  • @egreg, unfortunately your fix for expl3 from 1.1.2019 doesn't help. Now i'm in big troubles due to large numbers of my images use the calligraphypackage. who knows how long we will need to way for new version of the calligraphy package ... :-( anyway, thenk you very much for help! – Zarko Jan 05 '19 at 23:58

    Make a local copy of spath3.sty, in which you remove the rogue \cs_generate_variant:Nn commands on line 197. Fix also \SPathInfoInto as indicated and add the other fix at the beginning. Then mail the package author. – egreg Jan 06 '19 at 00:04
  • @egreg, thank you very much for suggestion. i will try this during Sunday, now is time for sleep :-) – Zarko Jan 06 '19 at 00:07
  • Better yet, add at the start, just before the first \tl_new:Nn instruction, \int_new:N \g__spath_map_int and replace every occurrence of \g__prg_map_int with \g__spath_map_int. – egreg Jan 06 '19 at 00:11
  • @egreg, i do as you suggested: (i) store original spath3.sty (as spath3-original), (ii) remove ˙line 197 with \cs_generate_variant:Nn \spath_get:nnN {nnV,VnN,VnV}, (iii) store correctedspath3` . Now works! Thank you very much! – Zarko Jan 06 '19 at 14:26
  • @Zarko I mailed the author. – egreg Jan 06 '19 at 14:43
  • @egreg, me too, just now :) – Zarko Jan 06 '19 at 15:16

    Hi all. The plethora of emails I just received led me to this question! Could you try to regenerate the files from spath3.dtx available from https://github.com/loopspace/spath3 and let me know if that fixes things. If so, I'll get it uploaded to CTAN. – Andrew Stacey Jan 06 '19 at 15:47
  • @LoopSpace, i try to extract spath3, however since i'm not familiar with dtx files, so there i high probability that i made same basics errors. the resulted spath3.sty doesn't works ... it has a bunch of text belonging to comments. please, can you provide as addition to dtx. file already extracted spath3.sty file for test? – Zarko Jan 06 '19 at 17:21
  • @Zarko I'll email it to you, but FYI running tex spath3.dtx generates the new files "behind the scenes". You see a load of comments in the terminal, but it also writes out the files. – Andrew Stacey Jan 06 '19 at 17:45
  • @LoopSpace Thanks for the github link. As far as I could see this is not in ctan yet so let me confirm that this fixes the problem. Thanks btw for your package! –  Feb 12 '19 at 03:46
  • @Andrew, i used it regularly. it works fine. it is awesome package. – Zarko Feb 12 '19 at 09:45
  • Thanks for the prod - I've just uploaded it to CTAN. Fingers crossed that I managed to do it correctly! – Andrew Stacey Feb 12 '19 at 20:39
