Server extract fails on Windows 11 Powershell because it tries to use gzip

[dyskette]

Hi 👋

It looks like my installation of codeium in neovim cannot extract the downloaded server gzip file. I saw in another issue that it is supposed to find out if it's currently using powershell and in that case use a script to extract the downloaded archive, but in my case it just fails with the following message:

Error executing vim.schedule lua callback: ...ta/Local/nvim-data/lazy/plenary.nvim/lua/plenary/job.lua:108:

I am using Windows 11 and Powershell Core 7.4.3

I checked if maybe I had some gzip command, and it looks like that is not the case:

Get-Command gzip
Get-Command: The term 'gzip' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

I checked in neovim's cmdline trying to find gzip :lua print(vim.fn.executable("gzip")) and it returns 0.

My installation is pretty straightforward, it's basically the same as in the README with the cmp source configured.

return {
    "Exafunction/codeium.nvim",
    dependencies = {
        "nvim-lua/plenary.nvim",
        "hrsh7th/nvim-cmp",
    },
    config = function()
        require("codeium").setup({})
    end,
}

For now, in my local installation I did a small change to fix it.

diff --git a/lua/codeium/io.lua b/lua/codeium/io.lua

 function M.gunzip(path, callback)
-       if M.executable("gzip") then
+       local gzipAvailable = vim.fn.executable("gzip") == 1
+       if gzipAvailable then
                M.job({
                        "gzip",
                        "-d",

BTW, while I'm not too familiar with lua and vim functions, I was testing in the cmdline how lua evaluates vim.fn.executable in an if. It looks like it results in a unintuitive result on Windows, because when vim.fn.executable returns 0 it gets evaluated as true and 1 gets evaluated as false. I think it's necessary to force the comparison to the expected result, e.g. vim.fn.executable("gzip") == 1.

If I'm wrong, just ignore my comment, but I saw others if statements relying on vim.fn.executable as well that probably need some review.

I solved it by enabling gzip as executable from CMD. You can install cygwin and add to PATH. Also you can install it with following command: choco install cygwin
