Add support for non-interactive bootstrapping

[x0wllaar]

Currently, bootstrapping NvChad requires interactive input on the first run, which makes it impossible to use in Dockerfiles. This PR adds a way to answer the "Do you want to install example custom config?" prompt non-interactively via an environment variable.

To run bootstrapping non-interactively, set the NVCHAD_INSTALL_EXAMPLE_CONFIG environment variable to the answer you want, and then run nvim, e.g.:

NVCHAD_INSTALL_EXAMPLE_CONFIG=no nvim -c "autocmd User PackerComplete quitall" -c "quitall"

Which will automatically do all bootstrapping without installing the example config and then immediately exit.

there should be a cleaner way to do this imo, i'll look into it this weekend

I suggest just changing line 43 to:

local input = env.NVCHAD_INSTALL_EXAMPLE_CONFIG or fn.input "Do you want to install example custom config? (y/N): "

instead of creating an unnecessary function that won't ever be used again

This is interesting.

Any update on this workaround?

env is always empty here, how does one set env var?

Well, Technically we can use something like
nvim +"NoInput" or something like that while NoInput being a bool to check while first installation?

Hey, there's a method you can use: nvim_create_user_command(). If users provides the cmd, proceed; otherwise, prompt them for input. For example.

vim.api.nvim_create_user_command("NoInput", function ()
local file = io.open("foo.txt", "w")
if file then
    file:close()
else
    print("Error creating the file.")
end
end,{})

This creates a file if they provide nvim +"NoInput"

@siduck in this specific codeblock env is set to vim.env which assumes all environment variables set at runtime.

oh cool, ive to actually read the PR now

[lucario387]

why again?

vim.env.NVCHAD_EXAMPLE_CONFIG can be yes and it will fail, even though the intention is probably to still install example config

[siduck]

wym again?

vim.env.NVCHAD_EXAMPLE_CONFIG can be yes and it will fail

such users are supposed to keep it y or n ,if it fails then its their problem. We have provided env var check then they must follow it

[lucario387]

And now the next question. Where is the documentation for the env var?
