PDF tab does not automatically get refreshed upon finishing building project.

Preliminary questions [Required]

I found that the pdf tab does not automatically get refreshed upon finishing building project. I have disabled all the other extensions except Latex Workshop, still, see this issue.

This project is successfully built, and I have opened the pdf tab. If I click the refresh all viewers, the pdf tab would be refreshed. I peek into the developer tools, and the outputs of the extension log are as follows:

There are some warnings when I open the pdf tab with ‘view Latex pdf’:

Disable all the other extensions except for LaTeX Workshop, restart VS Code, and check that you still see this issue. [Required]

You still see this issue?: Yes

Make sure to visit the wiki FAQ before filling an issue.

You visited the wiki?: Yes

If your issue is with compiling a document (not having to do with finding the root file of a project), check first that you can compile manually.

You can compile a TeX document manually?: Yes

I cannot reproduce this bug. Can you please provide a minimal working example?

[XinzeZhang]

Clone the repository in https://github.com/XinzeZhang/HUST-PhD-Thesis-Latex, build the project with the recipe as:

    "latex-workshop.latex.recipes": [
        {
            "name": "xelatex -> bibtex -> xelatex*2",
            "tools": [
                "xelatex",
                "bibtex",
                "xelatex",
                "xelatex"
            ]
        }
    ],

where the xelatex tool and bibtex are defined as:

    {
        "name": "xelatex",
        "command": "latexmk",
        "args": [
            "-xelatex",
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "%DOC%"
        ],
        "env": {}
    },  
    {
        "name": "bibtex",
        "command": "bibtex",
        "args": [
            "%DOCFILE%"
        ],
        "env": {}
    },

[James-Yu]

Please make it minimal. Thanks.

[XinzeZhang]

Sorry, I will create an example and reply latter.

[XinzeZhang]

Thanks for the reply. The problem has been solved by changing the definition of 'xelatex' to the following:

    {
        "name": "xelatex",
        "command": "xelatex",
        "args": [
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "%DOC%"
        ],
        "env": {}
    }

But the reason why using latexmk -xelatex would cause the auto-refresh and auto-clean to fail has not been figured out by me.

[XinzeZhang]

This problem occurred in my all projects using xelatex to compile Chinese-language-based projects at the last version ‘8.29.0’ of the extension. My tex version is Tex live 2021.

[James-Yu]

Good to know you solved the problem. I also have several projects built with latexmk and xelatex, and I cannot reproduce your issue.
