Lite XL has support for high DPI display on Windows and Linux and,
since 1.16.7 release, it supports **retina displays** on macOS.
Please note that Lite XL is compatible with lite for most plugins and all color themes.
We provide a separate lite-plugins repository for Lite XL, because in some cases some adaptations may be needed to make them work better with Lite XL.
The repository with modified plugins is http://github.com/franko/lite-plugins.

## Customization
Additional functionality can be added through plugins which are available in
the [plugins repository](https://github.com/rxi/lite-plugins) or in the [Lite XL-specific plugins repository](https://github.com/franko/lite-plugins).
Additional color themes can be found in the [colors repository](https://github.com/rxi/lite-colors).
Additional functionality can be added through plugins which are available in
the [plugins repository] or in the [Lite XL plugins repository].
Additional color themes can be found in the [colors repository].
These color themes are bundled with all releases of Lite XL by default.
The editor can be customized by making changes to the [user module](data/user/init.lua).
## Building
You can build Lite XL yourself using Meson.
In addition, the `build-packages.sh` script can be used to compile Lite XL and create an OS-specific package for Linux, Windows or Mac OS.
The following libraries are required:
- freetype2
- SDL2
The following libraries are **optional**:
- libagg
- Lua 5.2
If they are not found, they will be downloaded and compiled by Meson.
Otherwise, if they are present, they will be used to compile Lite XL.
On Debian-based systems the required libraries and Meson can be installed using the following commands:
```sh
# To install the required libraries:
sudo apt install libfreetype6-dev libsdl2-dev
# To install Meson:
sudo apt install meson
# or pip3 install --user meson
```
To build Lite XL with Meson the commands below can be used:
```sh
meson setup --buildtype=release build
meson compile -C build
meson install -C build
```
If you are using a version of Meson below 0.54 you need to use diffent commands to compile and install:
```sh
meson setup --buildtype=release build
ninja -C build
ninja -C build install
```
When performing the `meson setup` command you may enable the `-Dportable=true` option to specify whether files should be installed as in a portable application.
If `portable` is enabled, Lite XL is built to use a `data` directory placed next to the executable.
Otherwise, Lite XL will use unix-like directory locations.
In this case, the `data` directory will be `$prefix/share/lite-xl` and the executable will be located in `$prefix/bin`.
`$prefix` is determined when the application starts as a directory such that `$prefix/bin` corresponds to the location of the executable.
The `user` directory does not depend on the `portable` option and will always be `$HOME/.config/lite-xl`.
`$HOME` is determined from the corresponding environment variable.
As a special case on Windows the variable `$USERPROFILE` will be used instead.
If you compile Lite XL yourself, it is recommended to use the script `build-packages.sh`:
```sh
bash build-packages.sh <arch>
```
The script will run Meson and create a zip file with the application or, for linux, a tar compressed archive.
Lite XL can be easily installed by unpacking the archive in any directory of your choice.
On Windows two packages will be created, one called "portable" using the "data" folder next to the executable and
the other one using a unix-like file layout. Both packages works correctly. The one with unix-like file layout
is meant for people using a unix-like shell and the command line.
Please note that there aren't any hard-coded directories in the executable, so that the
package can be extracted and used in any directory.
Mac OS X is fully supported and a notarized app disk image is provided in the release page.
In addition the application can be compiled using the generic instructions given above.
## Contributing
Any additional functionality that can be added through a plugin should be done
as a plugin, after which a pull request to the
[plugins repository](https://github.com/rxi/lite-plugins) can be made.
If the plugin uses any Lite XL-specific functionality, please open a pull request to the
[Lite XL plugins repository](https://github.com/franko/lite-plugins).

Lite XL is following closely [rxi/lite](https://github.com/rxi/lite) but with some enhancements.
This files document the changes done in Lite XL for each release.
### 1.16.11
When opening directories with too many files lite-xl now keep diplaying files and directories in the treeview.
The application remains functional and the directories can be explored without using too much memory.
In this operating mode the files of the project are not indexed so the command "Core: Find File" will act as the "Core: Open File" command.
The "Project Search: Find" will work by searching all the files present in the project directory even if they are not indexed.
Implemented changing fonts per syntax group by @liquidev.
Example user module snippet that makes all comments italic:
```lua
local style = require "core.style"
-- italic.ttf must be provided by the user
local italic = renderer.font.load("italic.ttf", 14)
style.syntax_fonts["comment"] = italic
```
Improved indentation behavior by @adamharrison.
Fix bug with close button not working in borderless window mode.
Fix problem with normalization of filename for opened documents.
### 1.16.10
Improved syntax highlight system thanks to @liquidev and @adamharrison.
Thanks to the new system we provide more a accurate syntax highlighting for Lua, C and C++.
Other syntax improvements contributed by @vincens2005.
Move to JetBrains Mono and Fira Sans fonts for code and UI respectively.
Thet are provided under the SIL Open Font License, Version 1.1.
See `doc/licenses.md` for license details.
Fixed bug with fonts and rencache module.
Under very specific situations the application was crashing due to invalid memory access.
Add documentation for keymap binding, thanks to @Janis-Leuenberger.
Added a contributors page in `doc/contributors.md`.
### 1.16.9
Fix a bug related to nested panes resizing.

# lite
![screenshot](https://user-images.githubusercontent.com/3920290/81471642-6c165880-91ea-11ea-8cd1-fae7ae8f0bc4.png)
## Overview
Lite is a lightweight text editor written mostly in Lua — it aims to provide
something practical, pretty, *small* and fast, implemented as simply as
possible; easy to modify and extend, or to use without doing either.
Lite XL is based on the Lite editor itself and provide some enhancements
while remaining generally compatible with Lite.
## Getting Started
Lite works using a *project directory* — this is the directory where your
project's code and other data resides.
To open lite with a specific project directory the directory name can be passed
as a command-line argument *(`.` can be passed to use the current directory)* or
the directory can be dragged onto either the lite executable or a running
instance of lite.
Once started the project directory can be changed using the command
`core:change-project-folder`. The command will close all the documents
currently opened and switch to the new project directory.
If you want to open a project directory in a new window the command
`core:open-project-folder` will open a new editor window with the selected
project directory.
The main way of opening files in lite is through the `core:find-file` command
— this provides a fuzzy finder over all of the project's files and can be
opened using the **`ctrl+p`** shortcut by default.
Commands can be run using keyboard shortcuts, or by using the `core:find-command`
command bound to **`ctrl+shift+p`** by default. For example, pressing
`ctrl+shift+p` and typing `newdoc` then pressing `return` would open a new
document. The current keyboard shortcut for a command can be seen to the right
of the command name on the command finder, thus to find the shortcut for a command
`ctrl+shift+p` can be pressed and the command name typed.
## User Module
lite can be configured through use of the user module. The user module can be
used for changing options in the config module, adding additional key bindings,
loading custom color themes, modifying the style or changing any other part of
lite to your personal preference.
The user module is loaded by lite when the application starts, after the plugins
have been loaded.
The user module can be modified by running the `core:open-user-module` command
or otherwise directly opening the `$HOME/.config/lite-xl/init.lua` file.
On Windows, the variable `$USERPROFILE` will be used instead of
`$HOME`.
Please note that Lite XL differs from the standard Lite editor for the location
of the user's module.
## Project Module
The project module is an optional module which is loaded from the current
project's directory when lite is started. Project modules can be useful for
things like adding custom commands for project-specific build systems, or
loading project-specific plugins.
The project module is loaded by lite when the application starts, after both the
plugins and user module have been loaded.
The project module can be edited by running the `core:open-project-module`
command — if the module does not exist for the current project when the
command is run it will be created.
## Add directories to a project
In addition to the project directories it is possible to add other directories
using the command `core:add-directory`.
Once added a directory it will be shown in the tree-view on the left side and
the additional files will be reachable using the `ctrl+p` command (find file).
The additonal files will be also visible when searching across the project.
The additional directories can be removed using the command `core:remove-directory`.
When you will open again Lite XL on the same project folder the application will
remember your workspace including the additonal project directories.
Since version 1.15 Lite XL does not need a workspace plugin as it is now
bundled with the editor.
## Create new empty directory
Using the command `files:create-directory` or control-click in a directory in the
tree-view to create a new empty subdirectory.
## Commands
Commands in lite are used both through the command finder (`ctrl+shift+p`) and
by lite's keyboard shortcut system. Commands consist of 3 components:
* **Name** — The command name in the form of `namespace:action-name`, for
example: `doc:select-all`
* **Predicate** — A function that returns true if the command can be ran, for
example, for any document commands the predicate checks whether the active
view is a document
* **Function** — The function which performs the command itself
Commands can be added using the `command.add` function provided by the
`core.command` module:
```lua
local core = require "core"
local command = require "core.command"
command.add("core.docview", {
["doc:save"] = function()
core.active_view.doc:save()
core.log("Saved '%s', core.active_view.doc.filename)
end
})
```
Commands can be performed programatically (eg. from another command or by your
user module) by calling the `command.perform` function after requiring the
`command` module:
```lua
local command = require "core.command"
command.perform "core:quit"
```
## Keymap
All keyboard shortcuts in lite are handled by the `core.keymap` module. A key
binding in lite maps a "stroke" (eg. `ctrl+q`) to one or more commands (eg.
`core:quit`). When the shortcut is pressed lite will iterate each command
assigned to that key and run the *predicate function* for that command — if the
predicate passes it stops iterating and runs the command.
An example of where this used is the default binding of the `tab` key:
``` lua
["tab"] = { "command:complete", "doc:indent" },
```
When tab is pressed the `command:complete` command is attempted which will only
succeed if the command-input at the bottom of the window is active. Otherwise
the `doc:indent` command is attempted which will only succeed if we have a
document as our active view.
A new mapping can be added by your user module as follows:
```lua
local keymap = require "core.keymap"
keymap.add { ["ctrl+q"] = "core:quit" }
```
## Plugins
Plugins in lite are normal lua modules and are treated as such — no
complicated plugin manager is provided, and, once a plugin is loaded, it is never
expected be to have to unload itself.
To install a plugin simply drop it in the `plugins` directory in the user
module directory.
When Lite XL starts it will first load the plugins included in the data directory
and will then loads the plugins located in the user module directory.
To uninstall a plugin the
plugin file can be deleted — any plugin (including those included with lite's
default installation) can be deleted to remove its functionality.
If you want to load a plugin only under a certain circumstance (for example,
only on a given project) the plugin can be placed somewhere other than the
`plugins` directory so that it is not automatically loaded. The plugin can
then be loaded manually as needed by using the `require` function.
Plugins can be downloaded from the [plugins repository](https://github.com/rxi/lite-plugins).
## Restarting the editor
If you modifies the user configuration file or some of the Lua implementation files you may
restart the editor using the command `core:restart`.
All the application will be restarting by keeping the window that is already in use.
## Color Themes
Colors themes in lite are lua modules which overwrite the color fields of lite's
`core.style` module.
Pre-defined color methods are located in the `colors` folder in the data directory.
Additional color themes can be installed in the user's directory in a folder named
`colors`.
A color theme can be set by requiring it in your user module:
```lua
core.reload_module "colors.winter"
```
In the Lite editor the function `require` is used instead of `core.reload_module`.
In Lite XL `core.reload_module` should be used to ensure that the color module
is actually reloaded when saving the user's configuration file.
Color themes can be downloaded from the [color themes repository](https://github.com/rxi/lite-colors).
They are included with Lite XL release packages.
