Forward search not working with outdir

[tiagovla]

This is a duplicate of #147. I could not get it to work with zathura + neovim.
It works fine if the aux/output files are inside the current directory, i.e. ..
It does not if the aux/output files are in a subfolder, e.g. ./build.

Versions

Texlab: 4.0.0
Latexmk: 4.77
Nvim: v0.8.0-dev

Settings

    settings = {
        texlab = {
            diagnosticsDelay = 50,
            build = {
                outputDirectory = "build",
                auxDirectory = "build",
                executable = "latexmk",
                args = {
                    "-pdf",
                    "-pdflatex=lualatex",
                    "-quiet",
                    "-interaction=nonstopmode",
                    "-synctex=1",
                    "-shell-escape",
                    "-pv",
                    "-f",
                    "-outdir=build",
                    "%f",
                },
            },
            forwardSearch = {
                args = { "--synctex-forward", "%l:1:%f", "%p" },
                executable = "zathura",
            },
            chktex = { onOpenAndSave = true, onEdit = false },
            formatterLineLength = 120,
        },
    }

Debugging

I noticed that zathura is not called if the pdf file is not present in the current directory (.).
If it is present, forward search succeeds using the current directory file path.
No info on texlab's logs.
I suspect texlab searches for the pdf file in the current directory, doesn't find it and errors out without calling zathura.

Thanks for the detailed report. It looks like your configuration is not valid. The auxDirectory setting needs to be moved one level up: texlab.auxDirectory. The texlab.build.outputDirectory does not exist anymore so the value will be ignored.

@pfoerster I tried it with texlab.auxDirectory too. It isn't working for me. I still get Search Error.

@tiagovla From which directory are you calling nvim?
texlab currently searches the following directories for PDF files:

• If texlab.rootDirectory is set: <current working directory>/<texlab.rootDirectory>/<file_name>.pdf
• If texlab.auxDirectory is set: <current working directory>/<texlab.auxDirectory>/<file_name>.pdf
• <directory of TeX file>/<file_name>.pdf

I think the problem is that the working directory cannot be relied on with this setup.

[tiagovla]

I was calling nvim within a sub directory inside my .git project. I tried to move it to my project's root and it also didn't work.
I think I found the cause. Lspconfig was setting the root directory to my home instead of the .git path.
Now if my current working directory is the root directory it works.
It would be nice if texlab could check <current working directory>/<texlab.auxDirectory>/<file_name>.pdf anyways.

[pfoerster]

It would be nice if texlab could check /<texlab.auxDirectory>/<file_name>.pdf anyways.

This path is always checked even if texlab.rootDirectory is set. However, I added another set of paths to the search list, which should prevent this problem in the future:

<directory of TeX file>/<texlab.rootDirectory>/<file_name>.pdf
<directory of TeX file>/<texlab.auxDirectory>/<file_name>.pdf

EDIT: Released with v4.1.0
