Auto center on screen code about no-neck-pain.nvim

beautiful, centered, painless

Hey, thanks for the suggestion and using the plugin :D

So if I summarize, what you'd like is that NoNeckPain resizes to the width of the longest line in the buffer when entering in it?

Do you also expect a resize if the line gets deleted/shortened/extended?

---

This seems pretty specific but I can indeed understand the motivation especially if you rarely change buffers etc.

Hey, no problem I love your plugin.

Yeah so either provide a command to resize to longest line (ill just call it center) or even better if you could create an automatic center command that would be incredible I hadn't even thought of that, I actually use my center function then I have '-' & '=' bound to your width up & down

I would love the automatic resizing you suggested if that's possible that's pretty much a perfect solution but even centering on BufEnter would be cool with me :-)

another thing i might add is that the arbitrary extra 8 width i'm adding to the result of the wc command is due to this plugin including the margin in the total width. I don't know if this is doable but I think this plugin would be perfect outside of my afformentioned weird usecase if the width accounted for the margin meaning that a width of 80 means 80 characters after the margin rather than it being 80 characters wide total including the margin if that makes sense.

Thanks,
:-)

update: hey, i kind of found my own solution by modifying my script, i have also made it cross platform by using the wc command via https://github.com/uutils/coreutils crate.

DOCUMENT_WIDTH = 80
RECEIPT_WIDTH = 60

vim.api.nvim_create_user_command("Center", function()
    local filetype = vim.bo.filetype
    if filetype == "xxd" or filetype == "alpha" then
        vim.cmd("NoNeckPainResize " .. DOCUMENT_WIDTH)
        return
    elseif filetype == "text" then
        vim.cmd("NoNeckPainResize " .. RECEIPT_WIDTH)
        return
    end
    local path = vim.fn.expand("%:p")
    local command = io.popen("coreutils wc -L " .. path:gsub(" ", "\\ "))
    if command ~= nil then
        local result = command:read("*a")
        for i in string.gmatch(result, "%S+") do
            if tonumber(i) ~= nil then vim.cmd("NoNeckPainResize " .. i + 2) end
        end
    end
end, {})

vim.api.nvim_create_autocmd("BufWritePost", {
    pattern = "",
    command = "Center",
})

the most notable changes are the uses of either document width or receipt width as arbitrary values to fall back on as well as autocmd to center against a newly written buffer's file.

this implementation also works with file paths that include spaces and it also assumes that no gutter, numberline or symbols line is being used as per my new config.

Hey, that's awesome and looks super clean! I'll definitely look for a native implementation in Neovim in order to provide this as an option, thanks!!!

This auto-centering is super cool! What would make it even better is to set a maximum width, in case there are any rare super-long lines.
