Describe the bug [Required]

This has to do with #2910 which has been locked but which should be potentially fixable. In that previous issue the "bug" - in other words the failure of Windows files to compile with Luatex when there was a space in the filename or path was attributed to "We can do nothing on our side. This is related to latexmk and lualatex."

I was surprised to see this - because the Latex extension in Atom (which I have abandoned in favour of this great extension) copes with LuaTex files with spaces on Windows perfectly well.

as it happens the error can be corrected quite easily on a one-off basis by including a .latexmkrc file with the line
$MSWin_back_slash = 0; in the folder of the source tex file.

I'm not sure how Latex on Atom gets around this problem, but clearly it is possible without having to resort to individual local latexmkrc files.

To Reproduce

As #2910

then add the correcting file

Expected behavior

Since Atom Latex managed to resolve this problem, it seems likely that Latex-Workshop can achieve this as well, which would be good. It is not a fixed issue on the latexmk side.

Desktop [Required]

• OS: Windows 10
• VS Code version: 1.70.1
• Extension version: 8.29.0
• TeX distribution version: TeX Live 2021

Actually this issue should not have been closed yet again. Not sure why it was (doesn't make me - as someone who has a great deal of respect for this extension - feel very good)

It is clearly a bug and can easily be resolved by adding the
-MSWinBackSlash-
directive to the standard inbuilt lualatex recipe
and this has no effect on non-windows systems. Since this extensions recommends Texlive this directive is mandatory anyway (see latexmk documentation - and was missing)

    {
        "name": "lualatexmk",
        "command": "latexmk",
        "args": [
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "-lualatex",
            "-outdir=%OUTDIR%",
            "-MSWinBackSlash-"
            "%DOC%"
        ],
        "env": {}
    },

That is the reason. It’s not a bug of extension.
