Please note that the package is relocatable to any prefix and the option prefix
affects only the place where the application is actually installed.
## Installing Prebuilt
Head over to [releases](https://github.com/lite-xl/lite-xl/releases) and download the version for your operating system.
### Linux
Unzip the file and `cd` into the `lite-xl` directory:
```sh
tar -xzf <file>
cd lite-xl
```
To run lite-xl without installing:
```sh
cd bin
./lite-xl
```
To install lite-xl copy files over into appropriate directories:
```sh
mkdir -p $HOME/.local/bin && cp bin/lite-xl $HOME/.local/bin
cp -r share $HOME/.local
```
If `$HOME/.local/bin` is not in PATH:
```sh
echo -e 'export PATH=$PATH:$HOME/.local/bin' >> $HOME/.bashrc
```
To get the icon to show up in app launcher:
```sh
xdg-desktop-menu forceupdate
```
You may need to logout and login again to see icon in app launcher.
To uninstall just run:
```sh
rm -f $HOME/.local/bin/lite-xl
rm -rf $HOME/.local/share/icons/hicolor/scalable/apps/lite-xl.svg \
$HOME/.local/share/applications/org.lite_xl.lite_xl.desktop \
$HOME/.local/share/metainfo/org.lite_xl.lite_xl.appdata.xml \

This files document the changes done in Lite XL for each release.
### 2.0.3
Replace periodic rescan of project folder with a notification based system using the
[dmon library](https://github.com/septag/dmon). Improves performance especially for
large project folders since the application no longer needs to rescan.
The application also reports immediatly any change in the project directory even
when the application is unfocused.
Improved find-replace reverse and forward search.
Fixed a bug in incremental syntax highlighting affecting documents with multiple-lines
comments or strings.
The application now always shows the tabs in the documents' view even when a single
document is opened. Can be changed with the option `config.always_show_tabs`.
Fix problem with numeric keypad function keys not properly working.
Fix problem with pixel not correctly drawn at the window's right edge.
Treat correctly and open network paths on Windows.
Add some improvements for very slow network filesystems.
Fix problem with python syntax highliting, contributed by @dflock.
### 2.0.2
Fix problem project directory when starting the application from Launcher on macOS.

// Extra header functionality for dmon.h for the backend based on inotify

// Add/Remove directory functions:
// dmon_watch_add: Adds a sub-directory to already valid watch_id. sub-directories are assumed to be relative to watch root_dir
// dmon_watch_add: Removes a sub-directory from already valid watch_id. sub-directories are assumed to be relative to watch root_dir
// Reason: The inotify backend does not work well when watching in recursive mode a root directory of a large tree, it may take
// quite a while until all inotify watches are established, and events will not be received in this time. Also, since one
// inotify watch will be established per subdirectory, it is possible that the maximum amount of inotify watches per user
// will be reached. The default maximum is 8192.
// When using inotify backend users may turn off the DMON_WATCHFLAGS_RECURSIVE flag and add/remove selectively the
// sub-directories to be watched based on application-specific logic about which sub-directory actually needs to be watched.
// The function dmon_watch_add and dmon_watch_rm are used to this purpose.
