Inverse synctex doesn't work with Sioyek

[FahimAnayet]

This is what my configuration is. Only --reuse-instance removed (Sioyek v2.0.0 doesn't open if --reuse-instance used), everything else is default. Forward search is fine but when I enable synctex F4 then right click it doesn't do anything.

OS: macOS 12.6.1
iTerm2, nvim v0.9.0-dev-76-g45cc5fd76-dirty

 texoutputext = "pdf",
  textopdfviewerlaunch = "sioyek --inverse-search 'nvim --headless -es --cmd \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' %outputfile%",
  textopdfviewerrefresh = "none",
  textopdfforwardjump = "sioyek --inverse-search 'nvim --headless -es --cmd \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' --forward-search-file %srcfile% --forward-search-line %line% %outputfile%",
  textopdfshorterror = "A=%outputfile% ; LOGFILE=\"${A%.pdf}.log\" ; rubber-info \"$LOGFILE\" 2>&1 | head -n 1",
  delay = 10

It does seem that v2.0 of Sioyek has made some changes that will require removing --reuse-instance (or maybe changing to --reuse-window, which seems to be new flag, at least in the forward jump part, --new-window should be OK for the launch command), so thanks for mentioning that. I'll put out a new version fixing that right away.

However, inverse search works for me on linux with your settings. If the problem is mac-specific, I have no way of troubleshooting it, as I don't have a mac (and never will, cross my fingers). I'm kinda surprised you got it working on mac at all; I've certainly never tested it there.

Maybe some other mac user will come along and have an idea.

[FahimAnayet]

Alright, so I think it's a mac-specific problem. I believe the solution lies in knaphelper.lua this file. If anyone can find the soln. please open the thread. For now I am closing this.

[frabjous]

Thanks, but we might as well leave this open, so others who might be having the same trouble can find it. Out of curiosity, what does :echo v:servername show in Neovim?

[FahimAnayet]

/var/folders/f5/_l39kqr51s7b5zpzrtmhbwsc0000gn/T/nvim.MY_USER_NAME/LqNEwH/nvim.24523.0 this is what it spills out.

[frabjous]

Hmm, that's really complicated. I get something simpler like /run/user/1000/nvim.8183.0; still, it isn't clear why it wouldn’t work. Is nvim in your path? What does type -a nvim say in a terminal?

[FahimAnayet]

Definitely nvim is on my path. type -a nvim = nvim is /usr/local/bin/nvim in my terminal.

I also have encountered the same problem where the forward synctex works but not the inverse synctex. the <F4> key in sioyek doesn't make any change in the nvim buffer.

NVIM v0.8.2
kernel 6.1.9-1-MANJARO
echo v:servername return /run/user/1000/nvim.43428.0

knap config contains

    texoutputext = "pdf",
    textopdf = "pdflatex -interaction=batchmode -halt-on-error -synctex=1 %docroot%",
    textopdfviewerlaunch = "sioyek --inverse-search 'nvim --headless -es --cmd \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' --new-window %outputfile%",
    textopdfviewerrefresh = "none",
    textopdfforwardjump = "sioyek --inverse-search 'nvim --headless -es --cmd \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' --reuse-window --forward-search-file %srcfile% --forward-search-line %line% %outputfile%",
    textopdfshorterror = "A=%outputfile% ; LOGFILE=\"${A%.pdf}.log\" ; rubber-info \"$LOGFILE\" 2>&1 | head -n 1",
    delay = 250

The F4 key by itself isn't supposed to make any change to the nvim buffer. All the F4 key does is put you in "synctex mode" in Sioyek. (This should be indicated on the status bar in sioyek.) You then need to right click somewhere in the document to jump to the corresponding place in the buffer.

[joelsleeba]

Yes. Pressing the F4 key indicates in the status bar of the sioyek that I'm in "synctex mode". But then right clicking on the text or equation on the pdf doesn't make any changes in the buffer

[frabjous]

Works fine for me with your settings. What version of Sioyek are you using?

[FahimAnayet]

It still doesn't work for me too. I remember it works if I open sioyek separately from terminal and not from knap, which is a junky soln tbh. I don't recall the command though. If I could recall, I'll comment here.

[joelsleeba]

Sioyek is version 2.0.0
Also I forgot to mention I'm using LunarVim, which gets executed by lvim
I've also checked

The above config was when I was running nvim which had NvChad config and lvim which is LunarVim parallelly to see if it would give the inverse search result in either of them. It didn't work on nvim. Will the error be because the lvim command executes nvim with a custom init.lua file using the -u option?

Don't know why but change the code to the following solve the problem

        textopdfviewerlaunch = "sioyek --inverse-search 'nvim --headless -c \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' --new-window %outputfile%",
        textopdfviewerrefresh = "none",
        textopdfforwardjump = "sioyek --inverse-search 'nvim --headless -c \"lua require('\"'\"'knaphelper'\"'\"').relayjump('\"'\"'%servername%'\"'\"','\"'\"'%1'\"'\"',%2,%3)\"' --reuse-window --forward-search-file %srcfile% --forward-search-line %line% %outputfile%",

Here, -es is drop and --cmd is changed to -c. Both changes are necessary.
