For that one time where you need to explore your project's architecture

Semi WIP file tree plugin inspired by oil.nvim and carbon.nvim

Philosophy

• Minimalism
• Designed to be used with other FS plugins, I recommend oil.nvim
• Fast, navigating should feel instant

Features

I want to preface that this file tree right now does not have plans to support file operations such as move/copy/rename ... etc

• Navigating like a buffer
• Subsequent empty directories are flattened into one line
• Incremental rerendering of tree
• Xylene! opens xylene with the current file already opened
• Icons
• Execute any code with files / directories (for example open currently hovering directory in oil.nvim)
• Refresh files
• Symlink support
• Detect external file changes

Usage

While it's still missing some features listed above, I would be happy if you want to try it out

Install with your favorite package manager and call the setup function

Default options are listed below

require("xylene").setup({
  icons = {
    files = true,
    dir_open = "  ",
    dir_close = "  ",
  },
  indent = 4,
  sort_names = function(a, b)
    return a.name < b.name
  end,
  skip = function(name, filetype)
    return false
  end,
  on_attach = function(renderer) end,
  get_cwd = function()
    return vim.fn.getcwd()
  end,
  get_current_file_dir = function()
    return vim.fn.expand("%:p")
  end,
})

Quick start

Here setting up simple keymaps

• <cr> toggle current file
• ! toggle current file recursive

require("xylene").setup({
  on_attach = function(renderer)
    vim.keymap.set("n", "<cr>", function()
      renderer:toggle(vim.api.nvim_win_get_cursor(0)[1])
    end, { buffer = renderer.buf })

    vim.keymap.set("n", "!", function()
      renderer:toggle_all(vim.api.nvim_win_get_cursor(0)[1])
    end, { buffer = renderer.buf })
  end
})

User commands

• Xylene open a new/previous xylene buffer with cwd as the root & refresh the files
• Xylene! same as Xylene plus recursively opens directories to make your file seen

Recipes

            local entry = action_state.get_selected_entry()
            actions.close(prompt_bufnr)

            local path = vim.fs.joinpath(entry.cwd, entry[1])
            if path:sub(#path, #path) == "/" then
              -- remove trailing /
              path = path:sub(1, -2)
            end

            local file, line = renderer:open_from_filepath(path)

            vim.api.nvim_win_set_cursor(0, { line, file:indent_len() })
          end)

          return true
        end,
      })
    end, { buffer = renderer.buf })
  end

API

Main

local xylene = require("xylene")

xylene.setup()
-- get renderer from buffer
local renderer = xylene.renderer(buf)

Renderer

local renderer = require("xylene.renderer")

local buf = renderer.buf
local wd = renderer.wd

-- opens the file at `filepath` and returns the found file, line it's on
local file, line = renderer:open_from_filepath(filepath)

-- toggles the directory at `line`
renderer:toggle(line)
renderer:toggle_all(line) -- recursive variant

-- expensive!, refreshes all opened directories / files
renderer:refresh()

-- renders the `file` passed in
renderer:with_render_file(file, line, function()
  -- change `file` here, e.g. `file:toggle()`
end)

-- finds the file at `line`
local file = renderer:find_file_line(line)
-- finds the closest opened file from `filepath`
local file, line = renderer:find_file_filepath(filepath)

File

local file = require("xylene.file")

file:open()
file:open_all()
file:close()
file:close_all()

file:toggle()
file:toggle_all()

file:indent_len()
