Introduction

xplr is a terminal UI based file explorer that aims to increase our terminal productivity by being a flexible, interactive orchestrator for the ever growing awesome command-line utilities that work with the file-system.

To achieve its goal, xplr strives to be a fast, minimal and more importantly, hackable file explorer.

xplr is not meant to be a replacement for the standard shell commands or the GUI file managers. Rather, it aims to integrate them all and expose an intuitive, scriptable, keyboard controlled, real-time visual interface, also being an ideal candidate for further integration, enabling you to achieve insane terminal productivity.

Concept

Hackable

xplr is built with configurability in mind. So it allows you to perform a vast set of operations and make it look and behave just the way you want.

A few things you can do with the xplr configuration

Fast

Although speed is not the primary concern, xplr is already fast enough so that you can take it out for a walk into your node_modules or /nix/store any time you want, and it will only get faster. Still, if you feel like it's somehow making you slow, just report it. Most probably we're just waiting for someone to complain.

Tip: A quick and easy way to optimize the UI rendering is reducing the number of columns in the table.

Minimal

xplr is being referred to as a File Explorer, not a File Manager. This is because at the core, xplr is only an explorer, and outsources the file management operations to external commands. This helps xplr stay minimal, and focus only on doing what it does best.

So, just like speed, minimalism isn't as as aggressively pursued as hackability. xplr simply prefers to stay minimal and looks for the opportunity to lose some kb if it makes sense.

Features

Some of the coolest features xplr provide beside the basic stuff:

Embedded LuaJIT for portability and extensibility.
A simple system based on message passing to control xplr session using:
Readline-like input buffer with customizable behaviour to read user inputs.
Switchable recover mode that saves you from doing unwanted things when in a hurry.
Customizable layouts with built-in panels. For e.g.
- Selection list to show you the selected paths in real-time.
- Help menu to show you the available keys bindings in each mode.
- Input & logs to read input and display logs.
- Filter and sort pipeline to show you the applied filters and sorters.
Custom file properties with custom colors can be displayed in the table.
FIFO manager to manage a FIFO file that can be used to integrate with previewers.
Different quit options:
- Quit with success without any output (q).
- Quit with success and the result printed on stdout (enter).
- Quit with success and the present working directory printed on stdout (: q p).
- Quit with success and the path under focus printed on stdout (: q f).
- Quit with success and the selection printed on stdout (: q s).
- Quit with failure (ctrl-c).

Q. What features should be added here? let us know.

Quickstart

Nice to you have here! Let's quickly start with the following steps:

Try in Docker

If you prefer to try it before installing, here's the snippet for your convenience.

docker run -w / -it --rm ubuntu sh -uec '
  apt-get update -y
  apt-get install -y wget tar vim less
  wget https://github.com/sayanarijit/xplr/releases/latest/download/xplr-linux.tar.gz
  tar -xzvf xplr-linux.tar.gz
  ./xplr
'

Install

You can install xplr using one of the following ways. Each has their own advantages and limitations.

For example, the Direct Download, From crates.io, and Build From Source methods allow the users to install the latest possible version of xplr, but they have one common drawback - the user will need to keep an eye on the releases, and manually upgrade xplr when a new version is available.

One way to keep an eye on the releases is to watch the repository.

Android

Termux

Please note that xplr isn't heavily tested on Termux, hence things might need a little tweaking and fixing for a smooth usage experience.

Install build dependencies
```
pkg install rustc cargo make
```
Install xplr
```
cargo install --locked --force xplr
```
Setup storage
```
termux-setup-storage
```

Setup config and runtime dir

export XDG_CONFIG_HOME="$PWD/storage/.config"
export XDG_RUNTIME_DIR="$PWD/storage/run"

mkdir -p "$XDG_CONFIG_HOME" "$XDG_RUNTIME_DIR"

Run
```
~/.cargo/bin/xplr
```

Post Install

Once installed, use the following steps to setup and run xplr.

Create the customizable config file

mkdir -p ~/.config/xplr

version="$(xplr | grep ^version: | cut -d' ' -f 2)"

# When the app loads, press `#`

echo version = '"'${version:?}'"' > ~/.config/xplr/init.lua

Then copy from here and remove / comment out what you don't want to customize.

Note: You don't generally need to create the config file. You can use the default configuration for basic operations. However, creating the config file is recommended because the project is in its early stage and the defaults might change. Creating the config file will save you from unexpected behavior when you upgrade. Also, the default configuration is meant to be overwritten to suit your workflow.

Run

xplr

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

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.

Layouts

xplr layouts define the structure of the UI, i.e. how many panel we see, placement and size of the panels, how they look etc.

This is configuration exposed via the xplr.config.layouts API.

xplr.config.layouts.builtin contain some built-in panels which can be overridden, but you can't add or remove panels in it.

You can add new panels in xplr.config.layouts.custom.

Example: Defining Custom Layout

demo

xplr.config.layouts.builtin.default = {
  Horizontal = {
    config = {
      margin = 1,
      horizontal_margin = 2,
      vertical_margin = 3,
      constraints = {
        { Percentage = 50 },
        { Percentage = 50 },
      }

      },
    },
  },
}

xplr.config.general.initial_mode = "example"

Concept

These are the concepts that make xplr probably the most hackable terminal file explorer.

Key Bindings

Key bindings define how each keyboard input will be handled while in a specific mode.

See the Default key bindings for example.

To configure or work with key bindings, visit Configure Key Bindings.

In case you need help debugging key bindings or to understand the system DYI way, refer to the Debug Key Bindings guide.

Configure Key Bindings

In xplr, each keyboard input passes through a bunch of handlers (e.g. on_key, on_number, default etc.) in a given order. If any of the handlers is configured to with an action, it will intercept the key and produce messages for xplr to handle.

Try debug key bindings to understand how key bindings actually work.

Key Bindings

Key bindings contains the following information:

Tutorial: Adding a New Mode

Assuming xplr is installed and setup, let's add our own mode to integrate xplr with fzf.

We'll call it fzxplr mode.

First, let's add a custom mode called fzxplr, and map the key F to an action that will call fzf to search and focus on a file or enter into a directory.

xplr.config.modes.custom.fzxplr = {
  name = "fzxplr",
  key_bindings = {
    on_key = {
      F = {
        help = "search",
        messages = {
          {
            BashExec = [===[
            PTH=$(cat "${XPLR_PIPE_DIRECTORY_NODES_OUT:?}" | awk -F/ '{print $NF}' | fzf)
            if [ -d "$PTH" ]; then
              echo ChangeDirectory: "'"${PWD:?}/${PTH:?}"'" >> "${XPLR_PIPE_MSG_IN:?}"
            else
              echo FocusPath: "'"${PWD:?}/${PTH:?}"'" >> "${XPLR_PIPE_MSG_IN:?}"
            fi
            ]===]
          },
          "PopMode",
        },
      },
    },
    default = {
      messages = {
        "PopMode",
      },
    },
  },
}

As you can see, the key F in mode fzxplr (the name can be anything) executes a script in bash.

BashExec, PopMode, SwitchModeBuiltin, ChangeDirectory and FocusPath are messages, $XPLR_PIPE_MSG_IN, $XPLR_PIPE_DIRECTORY_NODES_OUT are environment variables exported by xplr before executing the command. They contain the path to the input and output pipes that allows external tools to interact with xplr.

Now that we have our new mode ready, let's add an entry point to this mode via the default mode.

xplr.config.modes.builtin.default.key_bindings.on_key["F"] = {
  help = "fzf mode",
  messages = {
    { SwitchModeCustom = "fzxplr" },
  },
}

Now let's try out the new xplr-fzf integration.

Default Key Bindings

The default key binding is inspired by vim and slightly overlaps with nnn, but it's supposed to be customized as per user requirements.

When you press ? in default mode, you can see the complete list of modes and the key mappings for each mode.

Also See:

xplr.config.layouts

Mode

A mode contains the following information:

The key bindings available in that mode.

layout

Type: nullable Layout

If specified, this layout will be used to render the UI.

Also See:

xplr.config.modes

Message

You can think of xplr as a server. Just like web servers listen to HTTP requests, xplr listens to messages.

You can send these messages to an xplr session in the following ways:

Via command-line (currently during start-up only, using --on-load)
Via key bindings
Via Lua function calls
Via shell command using the input pipe
Via socket (coming soon)

Format

To send messages using the key bindings or Lua function calls, messages are represented in Lua syntax. For example:

"Quit"
{ FocusPath = "/path/to/file" }
{ Call = { command = "bash", args = { "-c", "read -p test" } } }

However, to send messages using the input pipe, they need to be represented using YAML (or JSON) syntax. For example:

Quit
FocusPath: "/path/to/file"
Call: { command: bash, args: ["-c", "read -p test"] }

Also See:

Full List of Messages

Full List of Messages

xplr messages categorized based on their purpose.

Also See:

xplr.config.general.panel_ui.default.border_type = "Thick"
xplr.config.general.panel_ui.default.border_style.fg = "Black"
xplr.config.general.panel_ui.default.border_style.bg = "Gray"

Style

A style object contains the following information:

fg

Type: nullable Color

The foreground color.

bg

Type: nullable Color

The background color.

add_modifiers

Type: nullable list of Modifier

Modifiers to add.

sub_modifiers

Type: nullable list of Modifier

Modifiers to remove.

"Reset"
"Black"
"Red"
"Green"
"Yellow"
"Blue"
"Magenta"
"Cyan"
"Gray"
"DarkGray"
"LightRed"

xplr.config.general.prompt.style.bg = { Rgb = { 100, 150, 200 } }
xplr.config.general.prompt.style.add_modifiers = { "Bold", "Italic" }
xplr.config.general.prompt.style.sub_modifiers = { "Hidden" }

Sorting

xplr supports sorting paths by different properties. The sorting mechanism works like a pipeline, which in visible in the Sort & filter panel.

Example:

size↑ › [i]rel↓ › [c]dir↑ › [c]file↑ › sym↑

This line means that the nodes visible in the table will be first sorted by it's size, then by case insensitive relative path, then by the canonical (symlink resolved) type of the node, and finally by whether or not the node is a symlink.

The arrows denote the order.

Each part of this pipeline is called Node Sorter Applicable.

Node Sorter Applicable

It contains the following information:

sorter

A sorter can be one of the following:

"ByRelativePath"
"ByIRelativePath"
"ByExtension"
"ByIsDir"
"ByIsFile"
"ByIsSymlink"
"ByIsBroken"
"ByIsReadonly"
"ByMimeEssence"
"BySize"
"ByCreated"
"ByLastModified"
"ByCanonicalAbsolutePath"
"ByICanonicalAbsolutePath"
"ByCanonicalExtension"
"ByCanonicalIsDir"
"ByCanonicalIsFile"
"ByCanonicalIsReadonly"
"ByCanonicalMimeEssence"
"ByCanonicalSize"
"ByCanonicalCreated"
"ByCanonicalLastModified"
"BySymlinkAbsolutePath"
"ByISymlinkAbsolutePath"
"BySymlinkExtension"
"BySymlinkIsDir"
"BySymlinkIsFile"
"BySymlinkIsReadonly"
"BySymlinkMimeEssence"
"BySymlinkSize"
"BySymlinkCreated"
"BySymlinkLastModified"

TODO: document each

reverse

Type: boolean

It defined the direction of the order.

Example

xplr.config.general.initial_sorting = {
    { sorter = "ByCanonicalIsDir", reverse = true },
    { sorter = "ByIRelativePath", reverse = false },
}

This snippet defines the initial sorting logic to be applied when xplr loads.

Filtering

xplr supports filtering paths by different properties. The filtering mechanism works like a pipeline, which in visible in the Sort & filter panel.

Example:

rel!^. › [i]abs=~abc › [i]rel!~xyz

This line means that the nodes visible on the table will first be filtered by the condition: relative path does not start with ., then by the condition: absolute path contains abc (case insensitive), and finally by the condition: relative path does not contain xyz (case insensitive).

Each part of this pipeline is called Node Filter Applicable.

Node Filter Applicable

It contains the following information:

filter
input

filter

A filter can be one of the following:

"RelativePathIs"
"RelativePathIsNot"
"IRelativePathIs"
"IRelativePathIsNot"
"RelativePathDoesStartWith"
"RelativePathDoesNotStartWith"
"IRelativePathDoesStartWith"
"IRelativePathDoesNotStartWith"
"RelativePathDoesContain"
"RelativePathDoesNotContain"
"IRelativePathDoesContain"
"IRelativePathDoesNotContain"
"RelativePathDoesEndWith"
"RelativePathDoesNotEndWith"
"IRelativePathDoesEndWith"
"IRelativePathDoesNotEndWith"
"RelativePathDoesMatchRegex"
"RelativePathDoesNotMatchRegex"
"IRelativePathDoesMatchRegex"
"IRelativePathDoesNotMatchRegex"
"AbsolutePathIs"
"AbsolutePathIsNot"
"IAbsolutePathIs"
"IAbsolutePathIsNot"
"AbsolutePathDoesStartWith"
"AbsolutePathDoesNotStartWith"
"IAbsolutePathDoesStartWith"
"IAbsolutePathDoesNotStartWith"
"AbsolutePathDoesContain"
"AbsolutePathDoesNotContain"
"IAbsolutePathDoesContain"
"IAbsolutePathDoesNotContain"
"AbsolutePathDoesEndWith"
"AbsolutePathDoesNotEndWith"
"IAbsolutePathDoesEndWith"
"IAbsolutePathDoesNotEndWith"
"AbsolutePathDoesMatchRegex"
"AbsolutePathDoesNotMatchRegex"
"IAbsolutePathDoesMatchRegex"
"IAbsolutePathDoesNotMatchRegex"

TODO: document each

input

Type: string

The input for the condition.

Example:

ToggleNodeFilter = {
  filter = "RelativePathDoesNotStartWith",
  input = "."
}

Here, ToggleNodeFilter is a message that adds or removes (toggles) the filter applied.

Column Renderer

A column renderer is a Lua function that receives a special argument and returns a string that will be displayed in each specific field of the files table.

xplr by default provides the following column renderers:

xplr.fn.builtin.fmt_general_table_row_cols_0
xplr.fn.builtin.fmt_general_table_row_cols_1
xplr.fn.builtin.fmt_general_table_row_cols_2
xplr.fn.builtin.fmt_general_table_row_cols_3
xplr.fn.builtin.fmt_general_table_row_cols_4

You can either overwrite these functions, or create new functions in xplr.fn.custom and point to them.

Terminal colors are supported.

  { Percentage = 100 }
}

-- With this config, you should only see a single column displaying the
-- relative paths.

Lua Function Calls

xplr allows you to define lua functions using the xplr.fn.custom Lua API.

These functions can be called using messages like CallLua, CallLuaSilently.

When called the function receives a special argument that contains some useful information. The function can optionally return a list of messages which will be handled by xplr.

Example: Using Lua Function Calls

-- Define the function
xplr.fn.custom.ask_name_and_greet = function(app)
  print("What's your name?")

  local name = io.read()
  local greeting = "Hello " .. name .. "!"
  local message = greeting .. " You are inside " .. app.pwd

  return {
    { LogSuccess = message },
  }
end

-- Map the function to a key (space)
xplr.config.modes.builtin.default.key_bindings.on_key.space = {
  help = "ask name and greet",
  messages = {
    { CallLua = "custom.ask_name_and_greet" }
  }
}

-- Now, when you press "space" in default mode, you will be prompted for your
-- name. Enter your name to receive a nice greeting and to know your location.

Environment Variables and Pipes

Alternative to CallLua, CallLuaSilently messages that call Lua functions, there are Call, CallSilently, BashExec, BashExecSilently messages that call shell commands.

However, unlike the Lua functions, these shell commands have to read the useful information and send messages via environment variables and temporary files called "pipe"s. These environment variables and files are only available when a command is being executed.

Visit the fzf integration tutorial for example.

To see the environment variables and pipes, invoke the shell by typing :! in default mode and run the following command:

env | grep ^XPLR_

You will see something like:

XPLR_FOCUS_INDEX=0
XPLR_MODE=action to
XPLR_PIPE_SELECTION_OUT=/run/user/1000/xplr/session/122278/pipe/selection_out
XPLR_INPUT_BUFFER=
XPLR_PIPE_GLOBAL_HELP_MENU_OUT=/run/user/1000/xplr/session/122278/pipe/global_help_menu_out
XPLR_PID=122278
XPLR_PIPE_MSG_IN=/run/user/1000/xplr/session/122278/pipe/msg_in
XPLR_PIPE_LOGS_OUT=/run/user/1000/xplr/session/122278/pipe/logs_out
XPLR_PIPE_RESULT_OUT=/run/user/1000/xplr/session/122278/pipe/result_out
XPLR_PIPE_HISTORY_OUT=/run/user/1000/xplr/session/122278/pipe/history_out
XPLR_FOCUS_PATH=/home/sayanarijit/Documents/GitHub/xplr/docs/en/book
XPLR_SESSION_PATH=/run/user/1000/xplr/session/122278
XPLR_APP_VERSION=0.14.3
XPLR_PIPE_DIRECTORY_NODES_OUT=/run/user/1000/xplr/session/122278/pipe/directory_nodes_out

The environment variables starting with XPLR_PIPE_ are the temporary files called "pipe"s.

The other variables are single-line variables containing simple information:

Environment variables

XPLR_APP_VERSION

Self-explanatory.

XPLR_FOCUS_INDEX

Contains the index of the currently focused item, as seen in column-renderer/index.

XPLR_FOCUS_PATH

Contains the full path of the currently focused node.

XPLR_INPUT_BUFFER

The line currently in displaying in the xplr input buffer. For e.g. the search input while searching. See Reading Input.

XPLR_MODE

Contains the mode xplr is currently in, see modes.

XPLR_PID

Contains the process ID of the current xplr process.

XPLR_SESSION_PATH

Contains the current session path, like /tmp/runtime-"$USER"/xplr/session/"$XPLR_PID"/, you can find temporary files here, such as pipes.

Pipes

Input pipe

Currently there is only one input pipe.

XPLR_PIPE_MSG_IN

Output pipes

XPLR_PIPE_*_OUT are the output pipes that contain data which cannot be exposed directly via environment variables, like multi-line strings. These pipes can be accessed as plaintext files located in $XPLR_SESSION_PATH.

XPLR_PIPE_MSG_IN

Append new-line delimited messages to this pipe in YAML (or JSON) syntax. These messages will be read and handled by xplr after the command execution.

XPLR_PIPE_SELECTION_OUT

New-line delimited list of selected paths.

XPLR_PIPE_GLOBAL_HELP_MENU_OUT

The full help menu.

XPLR_PIPE_LOGS_OUT

New-line delimited list of logs.

XPLR_PIPE_RESULT_OUT

New-line delimited result (selected paths if any, else the focused path)

XPLR_PIPE_HISTORY_OUT

New-line delimited list of last visited paths (similar to jump list in vim).

XPLR_PIPE_DIRECTORY_NODES_OUT

New-line delimited list of paths, filtered and sorted as displayed in the files table.

Example: Using Environment Variables and Pipes

xplr.config.modes.builtin.default.key_bindings.on_key.space = {
  help = "ask name and greet",
  messages = {
    {
      BashExec = [===[
      echo "What's your name?"

      read name
      greeting="Hello $name!"
      message="$greeting You are inside $PWD"

      echo LogSuccess: '"'$message'"' >> "${XPLR_PIPE_MSG_IN:?}"
      ]===]
    }
  }
}

-- Now, when you press "space" in default mode, you will be prompted for your
-- name. Enter your name to receive a nice greeting and to know your location.

Another example: Simple file opener using xdg-open and $XPLR_FOCUS_PATH

xplr.config.modes.builtin.default.key_bindings.on_key.X = {
  help = "open",

      BashExecSilently = [===[
      xdg-open "${XPLR_FOCUS_PATH:?}"

Awesome Hacks

Here's a list of cool xplr hacks, i.e. snippets of code that you can just copy and paste into your configuration or the appropriate file, that are too small or too niche for a full fledge plugin.

Do you have something cool to share?

Edit this file or share them here or let us know.

cd on quit

Change directory using xplr.

Expand for details

Author: @sayanarijit
Tested on: Linux

With this alias set, you can navigate directories using xplr by entering xcd command, and when you quit by pressing enter, you will enter the directory.

You can of course, quit with plain Quit (i.e. by pressing q) to gracefully cancel "cd on quit".

alias xcd='cd "$(xplr --print-pwd-as-result)"'

Plugin

xplr supports pluggable Lua modules that can be used to easily configure or extend xplr UI and functionalities.

Installing Plugins

One way to install plugins is to use a plugin manager like dtomvan/xpm.xplr.

But you can also install and manage plugins manually.

Install Manually

Add the following line in ~/.config/xplr/init.lua

local home = os.getenv("HOME")
package.path = home
.. "/.config/xplr/plugins/?/init.lua;"
.. home
.. "/.config/xplr/plugins/?.lua;"
.. package.path

Clone the plugin

mkdir -p ~/.config/xplr/plugins

git clone https://github.com/sayanarijit/material-landscape2.xplr ~/.config/xplr/plugins/material-landscape2

Require the module in ~/.config/xplr/init.lua

require("material-landscape2").setup()

-- The setup arguments might differ for different plugins.
-- Visit the project README for setup instructions.

Luarocks Support

Some plugins may require luarocks to work.

Setup luarocks with the following steps:

Install luarocks (via your package managers or follow the official guide).
Add eval "$(luarocks path --lua-version 5.1)" in your .bashrc or .zshrc.
Add the following lines in ~/.config/xplr/init.lua
```
package.path = os.getenv("LUA_PATH") .. ";" .. package.path
package.cpath = os.getenv("LUA_CPATH") .. ";" .. package.cpath
```
Now you can install packages using luarocks. Be sure to append --lua-version.

Example:

luarocks install luafilesystem --local --lua-version 5.1

Writing Plugins

Anyone who can write Lua code, can write xplr plugins.

Just follow the instructions and best practices:

Naming

xplr plugins are named using hiphen (-) separated words that may also include integers. They will be plugged using the require() function in Lua.

Structure

A minimal plugin should confirm to the following structure:

.
├── README.md
└── init.lua

You can also use this template.

README.md

This is where you document what the plugin does, how to use it, etc.

init.lua

This file is executed to load the plugin. It should expose a setup() function, which will be used by the users to setup the plugin.

Example:

local function setup(args)
  local xplr = xplr
  -- do stuff with xplr
end

return { setup = setup }

Publishing

When publishing plugins on GitHub or other repositories, it's a best practice to append .xplr to the name to make them distinguishable. Similar to the *.nvim naming convention for Neovim plugins.

Finally, after publishing, don't hesitate to let us know.

Upgrade Guide

When you upgrade xplr, you might see an error like this

Incompatible script version in: /home/sayanarijit/.config/xplr/init.lua. The script version is: 0.9.0, the required version is: 0.10.1. Visit https://github.com/sayanarijit/xplr/wiki/Upgrade-Guide

All you need to do is follow the instructions starting from your config version, all the way to the required version.

Expand for more information

With every update, we either implement a major breaking change (e.g. deprecating or replacing messages), or a minor feature addition (e.g. adding new messages) or patch, fixes, and optimization (e.g. performance optimization).

Knowing that we use the {major}.{minor}.{patch} versioning format,

Major version mismatch are generally incompatible. xplr will fail with error.
Minor version upgrades (not downgrades) and patch fixes are backwards compatible. You might get notified by log a message which you can disable by updating the version in your config file.
However, if the config file has a higher value for the minor version than the app, then also xplr will fail with error, suggesting you to visit this page. Though in that case, you will be downgrading your config file based on your app version.

e.g.

1.0.0 -> 1.0.x: Bug fix (fully compatible).
1.0.0 -> 1.x.x: Only backwards compatible. You can't generally use for e.g. app-1.0.0 with config-1.1.0. But vice versa is fine.
1.0.0 -> x.x.x: Not compatible at all.

Note that until we're v1, we'll be using the {minor} version number as {major}, and the {patch} fix number as {minor} to determine compatibility.

Instructions

v0.18.0 -> v0.19.0

BREAKING: The builtin modes cannot be accessed using space separated names anymore. Use underscore separated mode names. For e.g. SwitchModeBuiltin: create file becomes SwitchModeBuiltin: create_file and so on. Kindly go through your config, find and update them, or copy from the latest init.lua.
Now you can use xplr.config.general.global_key_bindings to define a set of key bindings that are available by default in every mode. e.g. esc and ctrl-c, and remove boilerplate code from your config.
You can use the new builtin mode go_to_path which can be used for typing or pasting paths to enter into or to focus on. Type g p to enter this mode.
Now you can use basic tab completion in the go_to_path, create_file, create_directory, rename and duplicate_as modes.
Use the builtin function xplr.fn.builtin.try_complete_path to add easy tab completion support into your own configuration.
Now you can open OSC 7 compatible terminals into the xplr's current working directory by spawning new terminal sessions via the terminal supported key bindings.
Use NO_COLOR environment variable to disable OSC 7 compliance along with colors.
If you have fully copied the default init.lua locally, you might want to go through the latest improvements in init.lua. Specifically the search, filter and sort modes. Also, search for SetInputPrompt and the tab key bindings.

_{Like this project so far? Please consider contributing.}

v0.17.6 -> v0.18.0

Key binding f r and f R will now filter using regex.
Key binding f backspace will now remove the last filter.
Search mode now defaults to regex search.
Node metadata in the Lua API will contain two new fields:
- created
- last_modified
The last column in the files table now displays the last modification time.
You can now use --read0, --write0 and -0/--null to read and/or print null character delimited paths.
You can now the following regex filters:
- RelativePathDoesMatchRegex
- RelativePathDoesNotMatchRegex
- IRelativePathDoesMatchRegex
- IRelativePathDoesNotMatchRegex
- AbsolutePathDoesMatchRegex
- AbsolutePathDoesNotMatchRegex
- IAbsolutePathDoesMatchRegex
- IAbsolutePathDoesNotMatchRegex
You can use a new SetInputPrompt to set the input prompt dynamically.
You can now use the following timestamp based sorters:
- "ByCreated"
- "ByLastModified"
- "ByCanonicalCreated"
- "ByCanonicalLastModified"
- "BySymlinkCreated"
- "BySymlinkLastModified"

v0.16.4 -> v0.17.6

Deprecated app.directory_buffer, app.history, and app.last_modes in the custom dynamic layout renderer context. As of now, there's no way to access these fields in dynamic layouts. While app.history and app.last_modes can be re-added upon request (with justification), app.directory_buffer has been deprecated for good. However, there's no change in the CallLua* context.
Set xplr.config.general.hide_remaps_in_help_menu to true to hide the remaps in help menu.
None will be serialized to nil in Lua.
LuaEval can now return a function that will be called with the Lua Context argument. Refer to the Full List of Messages doc for example.
From version v0.17.1, set xplr.config.general.disable_debug_error_mode to true to disable switching to the "debug error" mode when startup errors occur.
From version v0.17.2, you can use CLI argument --print-pwd-as-result for cd on quit, and key binding ctrl-d to duplicate a path in the same directory with a different name.
Since version v0.17.3, you can use border_type, border_style to customize borders, and enforce_bounded_index_navigation to customize up/down navigation behavior when focus is on the top or bottom node.

v0.15.2 -> v0.16.4

Deprecated config.general.cursor. The default terminal cursor will be used for the time being.
Opening xplr inside a symlink will not resolve the path.
You can now replace most boilerplate configuration handling keys to send BufferInputFromKey, RemoveInputBufferLastCharacter, RemoveInputBufferLastWord, SetInputBuffer = "" etc. messages with a single UpdateInputBufferFromKey message.
You can now pass multiple paths as command-line arguments or via stdin to select paths, e.g. xplr -- $PWD /path/to/select/1 /path/to/select/2.
Pass --force-focus to focus on the first path even if it's a directory, e.g. xplr . --force-focus.
Use new messages LuaEval and LuaEvalSilently to run Lua code without needing to define a function. However, the app context won't be available.
You can now use new key handlers in the config:
- on_alphanumeric
- on_character
- on_navigation
- on_function

v0.14.7 -> v0.15.2

Deprecated config field from CallLua argument. Use the globally available xplr.config instead.
xplr.config.general.disable_recover_mode has been deprecated. Use xplr.config.general.enable_recover_mode instead.
Use xplr.config.general.focus_selection_ui to highlight selected files under focus differently than files under focus that are not selected.
Use PopModeKeepingInputBuffer, and SwitchMode alternatives to switching to different modes without resetting the input buffer.
Use the new CustomContent layout option to render custom content.
Use the new layout field in a mode to define custom layout for a specific mode.
Library users please refer to the latest API docs and examples.

v0.13.7 -> v0.14.7

macOS users need to place their config file (init.lua) in $HOME/.config/xplr/ or /etc/xplr/.
Library users please refer to the latest API docs.
Check out the new messages: {Start|Stop|Toggle}Fifo. These enable support for FIFO based file previews.
You can disable the recover mode using config.general.disable_recover_mode = true.
Try running xplr --help. Yes, CLI has been implemented.
Since version v0.14.3, StartFifo and ToggleFifo will write to the FIFO path when called. So, there's no need to pipe the focus path explicitely.
Since version v0.14.3, general config xplr.config.start_fifo is available which can be set to a file path to start a fifo when xplr starts.
Since version v0.14.4, $XPLR_SESSION_PATH can be used to dump session related data.
Since version v0.14.6, the -C or --extra-config CLI argument is available.

v0.12.1 -> v0.13.7

Lua functions called using CallLua and CallLuaSilently messages will receive CallLuaArg object as the function argument (instead of the App object).
Each node_types config will inherit defaults from matching less specifig node_types config and overwrite them.
Since version v0.13.2, you don't need to use/send Refresh anymore. It will be auto-handled by xplr.

v0.11.1 -> v0.12.1

xplr.config.node_types.mime_essence has split into type and subtype. Hence, instead of xplr.config.node_types.mime_essence["text/plain"] = .. use xplr.config.node_types.mime_essence["text"] = { plain = .. }.
You can also define xplr.config.node_types.mime_essence["text"]["*"] that will match all text types (text/*).

v0.10.2 -> v0.11.1

remaps: has been removed to avoid confusion. Use lua assignments instead. For e.g.

xplr.config.modes.builtin.default.key_bindings.on_key["v"] = xplr.config.modes.builtin.default.key_bindings.on_key.space

v0.9.1 -> v0.10.2

config.yml has been fully replaced with init.lua. If you have a lot of customization in your config.yml, xplr-yml2lua can help you with migrating it to init.lua.
Handlebars templates has been replaced with Lua functions. You can either remove the customizations or overwrite the functions accordingly.
Added new messages CallLua and CallLuaSilently to call lua functions. The app state will be passed as input to the functions, and the returned messages will be handled by xplr. CallLua and CallLuaSilently are more flexible (and probably faster) alternatives to Call, CallSilently, BashExec and BashExecSilently. e.g.

v0.9.0 -> v0.9.1

You can now set remaps: {key: null} to un-map a key.
gx will open the item under focus.
New key map :sx will open the selected items.

v0.8.0 -> v0.9.0

Your previous config should mostly work fine. However, in case you are using SwitchMode heavily in your custom config, follow along.

Introduced new message PopMode. You might want to use this message instead of SwitchMode* when returning back to the previous mode.
After using (the group of) PopMode and SwitchMode* messages, you are now required to Refresh manually to avoid the UI lag.
Pressing any invalid key will now lead you to the recover mode and will protect you from typing further invalid keys. Press esc to escape the recover mode.
Introduced new message LogWarning, similar to other Log* messages.
Creating files and directories has been optimized for batch creation.

v0.7.2 -> v0.8.0

If you have made changes to the config file,

Replace message Explore with ExplorePwd or ExplorePwdAsync or probably ExploreParentsAsync.
Pipe $XPLR_PIPE_FOCUS_OUT has been removed. Use $XPLR_FOCUS_PATH env var instead.
You might want to review your path escaping logics. For e.g. use echo FocusPath: "'"$PWD"'" >> $PIPE instead of echo "FocusPath: $PWD" >> $PIPE.

v0.7.0 -> v0.7.2

Just update the version in your config file.
For version >= v0.7.1, you might want to free up or remap the tab key in search mode to enable easy selection during search.

v0.6.0 -> v0.7.0

If you haven't made any changes in the config file, you should be fine just updating the version number. Else,

You can make the Table: ..., InputAndLogs: ... layout values null and define the common properties in the general.panel_ui instead.

v0.5.13 -> v0.6.0

If you haven't made any changes in the config file, you should be fine just updating the version number. Else,

Rename add_modifier: {bits: 1} to add_modifiers: [Bold], sub_modifier: {bits: 1} to sub_modifiers: [Bold] and so on.
Rename percentage: 10 to Percentage: 10, ratio: 1 to Ratio: 1 and so on.
You might want to free up or remap the ctrl-w key binding in default mode to enable layout switching.

Optionally, checkout this new theme to learn more about what's new.

v0.5.0 -> v0.5.13

Just update the version in your config file.
For versions >= v0.5.8, you can set $OPENER env var to declare a global GUI file opener (to open files using keys gx).
You might also want to update other mappings to handle files with names starting with - (hiphen). For example, instead of rm ${filename} use rm -- ${filename}. Same goes for cp, mv, cat, touch etc.
For version >= v0.5.13, you might want to use the more specific SwitchModeBuiltin and SwitchModeCustom messages instead of the general SwitchMode message.

v0.4.3 -> v0.5.0

If you haven't have any changes in the config file, you should be fine just updating the version number.

Else do the following

Replace {RelativePathIs, case_sensitive: true} with RelativePathIs.
Replace {RelativePathIs, case_sensitive: false} with IRelativePathIs.
Do the same with other filters you are using.
You might want to update your backspace handling to use the RemoveInputBufferLastCharacter message.
You might want to free-up f, s, ctrl-r and ctrl-u key bindings in the default mode, or remap them.
You might want to use the new UI variables.
Update your config version to v0.5.0.

v0.4.2 -> v0.4.3

If you have customized general.table.row.cols, you might want to update it to use the new variables with better symlink support.

v0.4.1 -> v0.4.2

In case you have mapped the keys q, ctrl-i and ctrl-o, you may want to revisit the default mode key bindings and remap accordingly to use the new functionalities.

v0.3.13 -> v0.4.1

A lot has changed (apologies). But I promise from now on, upgrading will be much less painful (thanks to @maximbaz's valuable inputs and code reviews).

So, to start with the upgrade, let's remove everything from your config file except the version field and your custom modifications. If version is the only thing remaining, update it to v0.4.1 and you are done.

Else, do the following

Rename general.focused_ui to general.focus_ui (see here).
Rename filetypes to node_types. (see here)
Rename custom field to meta. (see here)
Move icon to meta.icon. (see here)
Rename normal_ui to default_ui. (see here)
Split modes into modes.builtin and modes.custom (see here). Migrate your custom modes to modes.custom. And copy only the changes in the in-built modes in modes.builtin.
Finally, update the version to v0.4.1.

v0.3.8 -> v0.3.13

Your current config should work fine. However, you might want to replace some Call and BashExec messages with CallSilently and BashExecSilently to remove the flickering of the screen.

If you haven't made any changes to the configuration, you can delete and regenerate it.

Else, do the following

Check the new default config by temporarily removing your current config (with backup) and dumping the new config.
Search for Call and BashExec in the new config.
Compare and probably replace the associated actions in your current config

v0.3.0 -> v0.3.8

Your current config should work fine. However, you might want to replace some ResetNodeFilters messages with RemoveNodeFilter and RemoveNodeFilterFromInput to get a better search and filter experience.

If you haven't made any changes to the configuration, you can delete and regenerate it.

Else, do the following

Check the new default config by temporarily removing your current config (with backup) and dumping the new config.
Search for RemoveNodeFilterFromInput in the new config.
Compare and probably replace the associated actions in your current config.

v0.2.14 -> v0.3.0

If you haven't made any changes to the configuration, you can delete and regenerate it.

Else do the following:

$XPLR_APP_YAML has been removed. You can use Debug to export the app state.
$XPLR_RESULT has been ported to file $XPLR_PIPE_RESULT_OUT. Use cat instead of echo, < instead of <<< etc.
$XPLR_GLOBAL_HELP_MENU has been ported to file $XPLR_PIPE_GLOBAL_HELP_MENU_OUT. Use cat instead of echo, < instead of <<< etc.
$XPLR_DIRECTORY_NODES has been ported to file $XPLR_PIPE_DIRECTORY_NODES_OUT. Use cat instead of echo, < instead of <<< etc.
$XPLR_LOGS has been ported to file $XPLR_PIPE_LOGS_OUT. Use cat instead of echo, < instead of <<< etc.
$XPLR_PIPE_RESULT has been ported to file $XPLR_PIPE_RESULT_OUT. Use cat instead of echo, < instead of <<< etc.
Finally, update the version in your config file.
