Compilation fail with option "-c" about vimtex

[lervag]

As I said I do not use vim.cmd 'filetype plugin indent on' and vim.cmd 'syntax enable' as I read the comment. :)

Ok, cool. You included it in your original post, which is why I mentioned that.

When adding the following as suggested:

  init = function()
    vim.api.nvim_create_autocmd(
        "VimtexEventQuit",
        { command = "VimtexClean" }
    )
  end

Sorry, that's my mistake. It should be:

  init = function()
    vim.api.nvim_create_autocmd("User", {
        pattern = "VimtexEventQuit",
        group = vim.api.nvim_create_augroup("init_vimtex", {}),
        command = "VimtexClean"
    })
  end

I did read from the help page:

Note: Commands such as |:VimtexClean| cannot be used in this autocommand
because when quitting vim the current buffer does not necessarily have filetype "tex".

I think that comment may be wrong; I'm not 100% sure. Please test my updated version.

But I may use e.g. VimtexEventCompileSuccess

Yes, this is also an option, but you should only do it if you do not use continuous compilation.

Notice that for larger documents, LaTeX compilation times are sometimes nontrivial. Thus, cleaning after every compile implies that you need to fully recompile everything everytime. Thus, I think it is better to instead do a clean when you are finished working with your document.

Thank you for your precious help!

Glad to help!

I believe the last update should be good - the text is better now.

I have tried to use the compilation argument "-c" to automatically clean up the output files instead of running :VimtexClean every time.

That's not really possibly. :VimtexCompile starts latexmk in the background as a continuous process that compiles your document when you save it.

IMHO, there is really no reason to worry about the generated files. Just ignore them.

Also, please remove the vim.cmd 'filetype plugin indent on' and vim.cmd 'syntax enable' from your config. Those are not necessary when you use a plugin manager (as is mentioned in the very comments you've copied into your config!). Thus, you may simplify your config to this:

return {
    'lervag/vimtex',
    init = function()
        -- you could remove the init block if you are not setting any options
    end,
}

Also; if you really do want to add an option to latexmk, you should append to the default list. Thus:

return {
    'lervag/vimtex',
    init = function()
        vim.g.vimtex_compiler_latexmk = {
            options = {
                '-verbose',
                '-file-line-error',
                '-synctex=1',
                '-interaction=nonstopmode',
                '-c',
            },
        }
    end,
}

However, I still think it does not make sense to add -c when latexmk is run in continuous mode.

Regarding the config I just simply copied the example but I don't have it in otherwise.

The thing is, I have different tex files in the same directory so generating 7 files instead of 3 for every tex files adds up.

I have tried to run with and without continuous mode. But the compiler simply don't compile with the -c flag.
Does this clean option work at all then ?

Then take this advice: 1) read the comments in example code that you copy, and 2) strive to properly understand code that you are copying. The latter is sometimes takes time you feel that you don't have, but I believe in many cases you can actually reduce time waste by investing this time up front.

So, how about creating separate directories for your projects?

That's the expected behaviour. As far as I know, latexmk was never designed for doing compile then clean in the same invocation.

One thing you can try: Use an event to trigger clean when you exit neovim with something like this:

  init = function()
    vim.api.nvim_create_autocmd(
        "VimtexEventQuit",
        { command = "VimtexClean" }
    )
  end

I would have liked to, but I'm told to do so.

When adding the following as suggested:

  init = function()
    vim.api.nvim_create_autocmd(
        "VimtexEventQuit",
        { command = "VimtexClean" }
    )
  end

Even though I don't lazy load Vimtex I get:

Failed to run `init` for **vimtex**
.../.config/nvim-24/lua/ftplugin/tex.lua:43: Invalid 'event': 'VimtexEventQuit'

I did read from the help page:

Note: Commands such as |:VimtexClean| cannot be used in this autocommand
because when quitting vim the current buffer does not necessarily have filetype "tex".

You are correct, I did see now that latexmk cannot compile and then clean.
Was using it wrong.
(And I know it defeats its purpose to clean after every compilation.)

Thank you for your precious help!

   vim.api.nvim_create_autocmd("User", {
       pattern = "VimtexEventQuit",
       group = vim.api.nvim_create_augroup("init_vimtex", {}),
       command = "VimtexClean"
   })
 end

This works like a charm!
(Tried quitting from another buffer and the documentation seem to be correct)

Big thanks! Couldn't hope for a better solution.

[lervag]

Great, I'm glad to hear it!

It seems I should update the docs, though, as they are indicating that this specific thing does not work. Thanks for pointing that out!

[0xN1C04ND3]

It wasn't maybe not that clear in my phrase. Sorry. I mean the docs are correct in the current state.
When quitting from a buffer that is not of tex filetype, the command is not executed. :)

[lervag]

Ah, ok, sorry. Then I'll revert the docs :)
