Gatekeeper.nvim

This plugin intends to make buffers with from files outside of the current working directory read only and non modifiable. To do that it sets an auto command for every time a buffer gets loaded.

The purpose for the existence of this plugin is basically allowing to set white lists for folders or files.

Usage

Install with your favorite package manager and call

require('gatekeeper').setup({
-- default values
    exclude = {},
    exclude_regex = {},
    debug = false, -- will call vim.notify with info when it is being evaluated
})

Options

exclude

Specifies fully qualified folders or files to be excluded and being editable. It won't expand ~ to your home so you have to concatenate vim.fn.expand('~') to your desired folder, if that's the case. Example:

require('gatekeeper').setup({
    exclude = {
        vim.fn.expand('~/.config/nvim')
    }
})

exclude_regex

Specifies regex patterns to evaluate files to be excluded and being editable. If the buffer name matches the regex it won't be blocked from being edited. Example:

require('gatekeeper').setup({
    exclude_regex = {
        '.*\.config/nvim/.*' -- any file that contains ".config/nvim" in its full path
    }
})

debug

Will notify if a file is being blocked or not when it is evaluated.

Commands

You can call :GTForceWrite on any buffer to revert and force it to be writable and modifiable.

If you want to check why some buffer is or is not being blocked, you can call :GTExplain. It will print all checks on your settings against the current buffer until one evaluates to true (which means it found an exclusion/reason to not block).
