|
|
|
|
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.
|
|
|
|
The changes and differences between Lite XL and rxi/lite are listed in the [changelog](https://github.com/franko/lite-xl/blob/master/changelog.md).
|
|
|
|
## Overview
|
|
Lite XL is derived from lite. It is a lightweight text editor written mostly in Lua — it aims to provide
|
|
something practical, pretty, *small* and fast easy to modify and extend, or to use without doing either.
|
|
|
|
The aim of Lite XL compared to lite is to be more user friendly, improve the quality of font rendering, and reduce CPU usage.
|
|
|
|
## 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).
|
|
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 macOS.
|
|
|
|
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 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 build
|
|
ninja -C build
|
|
ninja -C build install
|
|
```
|
|
|
|
When performing the `meson setup` command you may enable the `-Dportable=true` option to specify whether a portable build should be done.
|
|
|
|
If `portable` is enabled, Lite XL is built to use `data` and `user` directories placed next to the executable.
|
|
Otherwise, Lite XL will use Unix-like directory locations.
|
|
In this case, the `data` directory will be located in `$prefix/share/lite-xl`, and the `user`
|
|
directory will be `$HOME/.config/lite-xl`.
|
|
`$prefix` is determined such that `$prefix/bin` corresponds to the location of the executable.
|
|
`$HOME` is determined from the corresponding environment variable.
|
|
As a special case on Windows the variable `$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 two .zip files, one for the portable version, and
|
|
another one for the Unix-like version. Lite XL can be easily installed by unpacking one
|
|
of these .zip archives in some directory of your choice.
|
|
|
|
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.
|
|
|
|
Note that the Unix-like package can also work on Windows.
|
|
|
|
Please note that while compiling Lite XL on macOS should work, macOS is not officially supported.
|
|
|
|
## 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).
|
|
|
|
Pull requests to improve or modify the editor itself are welcome.
