Configuration

xplr can be configured using Lua via a special file named init.lua, which can be placed in ~/.config/xplr/ (local to user) or /etc/xplr/ (global) depending on the use case.

When xplr loads, it first executes the built-in init.lua to set the default values, which is then overwritten by another config file, if found using the following lookup order:

--config /path/to/init.lua
~/.config/xplr/init.lua
/etc/xplr/init.lua

The first one found will be loaded by xplr and the lookup will stop.

The loaded config can be further extended using the -C or --extra-config command-line option.

Config

The xplr configuration, exposed via xplr.config Lua API contains the following sections.

See:

Function

While xplr.config defines all the static parts of the configuration, xplr.fn defines all the dynamic parts using functions.

See: Lua Function Calls

As always, xplr.fn.builtin is where the built-in functions are defined that can be overwritten.

xplr.fn.builtin.try_complete_path

Tries to auto complete the path in the input buffer

xplr.fn.builtin.fmt_general_table_row_cols_0

Renders the first column in the table

xplr.fn.builtin.fmt_general_table_row_cols_1

Renders the second column in the table

xplr.fn.builtin.fmt_general_table_row_cols_2

Renders the third column in the table

xplr.fn.builtin.fmt_general_table_row_cols_3

Renders the fourth column in the table

xplr.fn.builtin.fmt_general_table_row_cols_4

Renders the fifth column in the table

xplr.fn.custom

This is where the custom functions can be added.

There is currently no restriction on what kind of functions can be defined in xplr.fn.custom.

You can also use nested tables such as xplr.fn.custom.my_plugin.my_function to define custom functions.

This section of the configuration cannot be overwritten by another config file or plugin, since this is an optional lua return statement specific to each config file. It can be used to define things that should be explicit for reasons like performance concerns, such as hooks.

Plugins should expose the hooks, and require users to subscribe to them explicitly.

Example:

return {
  -- Add messages to send when the xplr loads.
  -- This is similar to the `--on-load` command-line option.
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_load = {
    { LogSuccess = "Configuration successfully loaded!" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_load" },
  },

  -- Add messages to send when the directory changes.
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_directory_change = {
    { LogSuccess = "Changed directory" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_directory_change" },
  },

  -- Add messages to send when the focus changes.
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_focus_change = {
    { LogSuccess = "Changed focus" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_focus_change" },
  }

  -- Add messages to send when the mode is switched.
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_mode_switch = {
    { LogSuccess = "Switched mode" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_mode_switch" },
  }

  -- Add messages to send when the layout is switched
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_layout_switch = {
    { LogSuccess = "Switched layout" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_layout_switch" },
  }

  -- Add messages to send when the selection changes
  --
  -- Type: list of [Message](https://xplr.dev/en/message#message)s
  on_selection_change = {
    { LogSuccess = "Selection changed" },
    { CallLuaSilently = "custom.some_plugin_with_hooks.on_selection_change" },
  }
}

Note:

It's not recommended to copy the entire configuration, unless you want to freeze it and miss out on useful updates to the defaults.

Instead, you can use this as a reference to overwrite only the parts you want to update.

If you still want to copy the entire configuration, make sure to put your customization before the return statement.
