-## Quick Build Guide
+The editor can be customized by making changes to the [user module](data/user/init.lua).
 
-If you compile Lite XL yourself, it is recommended to use the script
-`build-packages.sh`:
+## 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
-bash build-packages.sh -h
+# To install the required libraries:
+sudo apt install libfreetype6-dev libsdl2-dev
+
+# To install Meson:
+sudo apt install meson
+# or pip3 install --user meson
 ```
 
-The script will run Meson and create a tar compressed archive with the application or,
-for Windows, a zip file. Lite XL can be easily installed
-by unpacking the archive in any directory of your choice.
-
-Otherwise the following is an example of basic commands if you want to customize
-the build:
-
+To build Lite XL with Meson the commands below can be used:
 ```sh
-meson setup --buildtype=release --prefix <prefix> build
+meson setup --buildtype=release build
 meson compile -C build
-DESTDIR="$(pwd)/lite-xl" meson install --skip-subprojects -C build
+meson install -C build
 ```
 
-where `<prefix>` might be one of `/`, `/usr` or `/opt`, the default is `/`.
-To build a bundle application on macOS:
+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 --Dbundle=true --prefix / build
-meson compile -C build
-DESTDIR="$(pwd)/Lite XL.app" meson install --skip-subprojects -C build
+meson setup --buildtype=release build
+ninja -C build
+ninja -C build install
 ```
 
-Please note that the package is relocatable to any prefix and the option prefix
-affects only the place where the application is actually installed.
+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.
 
-## Installing Prebuilt
+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.
 
-Head over to [releases](https://github.com/lite-xl/lite-xl/releases) and download the version for your operating system.
+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.
 
-### Windows
-
-Lite XL comes with installers on Windows for typical installations.
-Alternatively, we provide ZIP archives that you can download and extract anywhere and run directly.
-
-To make Lite XL portable (e.g. running Lite XL from a thumb drive),
-simply create a `user` folder where `lite-xl.exe` is located.
-Lite XL will load and store all your configurations and plugins in the folder.
-
-### macOS
-
-We provide DMG files for macOS. Simply drag the program into your Applications folder.
-
-> **Important**
-> Newer versions of Lite XL are signed with a self-signed certificate,
-> so you'll have to follow these steps when running Lite XL for the first time.
->
-> 1. Find Lite XL in Finder (do not open it in Launchpad).
-> 2. Control-click Lite XL, then choose `Open` from the shortcut menu.
-> 3. Click `Open` in the popup menu.
->
-> The correct steps may vary between macOS versions, so you should refer to
-> the [macOS User Guide](https://support.apple.com/en-my/guide/mac-help/mh40616/mac).
->
-> On an older version of Lite XL, you will need to run these commands instead:
-> 
-> ```sh
-> # clears attributes from the directory
-> xattr -cr /Applications/Lite\ XL.app
-> ```
->
-> Otherwise, macOS will display a **very misleading error** saying that the application is damaged.
-
-### Linux
-
-Unzip the file and `cd` into the `lite-xl` directory:
+If you compile Lite XL yourself, it is recommended to use the script `build-packages.sh`:
 
 ```sh
-tar -xzf <file>
-cd lite-xl
+bash build-packages.sh <arch>
 ```
 
-To run lite-xl without installing:
-```sh
-./lite-xl
-```
+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.
 
-To install lite-xl copy files over into appropriate directories:
+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.
 
-```sh
-rm -rf  $HOME/.local/share/lite-xl $HOME/.local/bin/lite-xl
-mkdir -p $HOME/.local/bin && cp lite-xl $HOME/.local/bin/
-mkdir -p $HOME/.local/share/lite-xl && cp -r data/* $HOME/.local/share/lite-xl/
-```
-
-If `$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 \
-          $HOME/.local/share/lite-xl
-```
+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.

-# Lite XL v2 for AmigaOS 4.1 FE & MorphOS 3
-
-Lite XL is a lightweight text editor written in Lua and SDL2.
-
-The port is not perfect and it might have issues here and there. It might
-crash from time to time, if there is a path problem, but overall it works
-pretty well. This is my daily editor for any kind of development.
-If it crashes on your system, try to delete to `.config` folder.
-
-## Installation
-You can extract the Lite XL archive wherever you want and run the *lite*
-editor.
-
-## Configuration folder
-This editor creates a `.config` folder where the configuration is saved, as
-well as plugins, themes etc.. By default this version uses the installation
-folder, but if you want to override it, you can create an ENV variable
-named `HOME` and set there your prefferable path.
-
-You can check if there is one already set by executing the following command
-in a shell
-```
-GetEnv HOME
-```
-If there is one set, then you will see the path at the output.
-
-Otherwise, you can set your home path be executing the following command.
-Change the path to the one of your preference.
-```
-SetEnv SAVE HOME "Sys:home/"
-```
-
-## Addons
-### Colors
-Colors are lua files that set the color scheme of the editor. There are
-light and dark themes for you to choose.
-
-To install and use them you have to copy the ones you would like from
-`addons/colors/light` or `addons/colors/dark` into the folder
-`.config/lite-xl/colors/`. Don't add light or dark folders. Just copy the
-.lua files in there.
-
-Then you have to start Lite XL and open your configuration by clicking
-at the cog icon at the toolbar (bottom left sixth icon). Go at the line
-that looks like below
-```
--- core.reload_module("colors.summer")
-```
-and change the `summer` with the name of your color theme. Also, remove
-the two dashes `--` at the start of the line and save the file. If you
-did everything right, the color schema should change instantly.
-
-The themes can also be found at
-https://github.com/lite-xl/lite-xl-colors
-
-### Plugins
-LiteXL is able to use plugins to extend its features. Those can be found
-at https://github.com/lite-xl/lite-xl-plugins and other websites. Not all
-of them will work fine on AmigaOS 4 or MorphOS, because of missing
-dependencies or filesystem issues.
-
-To make it easier for you, I gathered some of the plugins that are working
-well, and I included them under `addons/plugins`. For you to install the
-ones you would like to use, you have to copy the `.lua` files into the
-folder `.config/lite-xl/plugins/` and restart the editor.
-
-Please, choose wisely, because adding all the plugins might make the editor
-slower on your system. I would recommend you add only those that you really
-need.
-
-The included plugins are the following:
-
-**autoinsert**
-Automatically inserts closing brackets and quotes. Also allows selected
-text to be wrapped with brackets or quotes.
-
-**autosaveonfocuslost**
-Automatically saves files that were changed when the main window loses
-focus by switching to another application
-
-**autowrap**
-Automatically hardwraps lines when typing
-
-**bigclock**
-Shows the current time and date in a view with large text
-
-**bracketmatch**
-Underlines matching pair for bracket under the caret
-
-**codesets**
-This plugin uses the codesets.library on AmigaOS 4 and the
-charsets.library on MorphOS to translate ISO encoded files to unicode
-and vice-versa. When this is enabled new menu items are added to
-load/save the code with a different encoding. Also there is a new
-section at the status bar that show the file encoding.
-This plugin is **EXPERIMENTAL** and heavily inspired from the encoding
-plugin at https://github.com/jgmdev/lite-xl-encoding
-
-**colorpreview**
-Underlays color values (eg. `#ff00ff` or `rgb(255, 0, 255)`) with their
-resultant color.
-
-**custom_caret**
-Customize the caret in the editor setting it to *underline*, *block* or
-*line* at the init.lua file in your config folder.
-For example add:
-`config.plugins.custom_caret.shape = "block"`
-
-**EditorConfig**
-EditorConfig (https://editorconfig.org/) implementation for Lite XL
-
-**ephemeral_tabs**
-Preview tabs. Opening a doc will replace the contents of the preview tab.
-Marks tabs as non-preview on any change or tab double clicking.
-
-**ghmarkdown**
-Opens a preview of the current markdown file in a browser window.
-On AmigaOS 4 it uses *urlopen* and on MorphOS it uses *openurl* to load
-the generated html in the browser. It requires a GitHub application token
-because it uses its Rest API. Add it at the init.lua file in your config
-folder like below:
-`config.plugins.ghmarkdown.github_token = "<token here>"`
-
-**indentguide**
-Adds indent guides
-
-**language_guide**
-Syntax for the AmigaGuide scripting language
-
-**language_hws**
-Syntax for the Hollywood language
-
-**language_make**
-Syntax for the Make build system language
-
-**language_sh**
-Syntax for shell scripting language
-
-**lfautoinsert**
-Automatically inserts indentation and closing bracket/text after newline
-
-**markers**
-Add markers to docs and jump between them quickly
-
-**minimap**
-Shows a minimap on the right-hand side of the docview. Please note that
-this plugin will make the editor slower on file loading and scrolling.
-
-**navigate**
-Allows moving back and forward between document positions, reducing the
-amount of scrolling
-
-**nonicons**
-File icons set for TreeView. Download TTF font to your config/fonts
-folder from https://github.com/yamatsum/nonicons/tree/master/dist
-
-**opacity**
-Change the opaqueness/transparency of lite-xl using LAmiga+mousewheel
-or a command.
-
-**openfilelocation**
-Opens the parent directory of the current file in the file manager
-
-**rainbowparen**
-Show nesting of parentheses with rainbow colours
-
-**restoretabs**
-Keep a list of recently closed tabs, and restore the tab in order on
-cntrl+shift+t.
-
-**select_colorscheme**
-Select a color theme, like VScode, Sublime Text.
-(plugin saves changes)
-
-**selectionhighlight**
-Highlights regions of code that match the current selection
-
-**smallclock**
-It adds a small clock at the bottom right corner.
-
-**tetris**
-Play Tetris inside Lite XL.
-
-## Tips and tricks
-### Transitions
-
-If you want to disable the transitions and make the editor faster,
-open your configuration file by clicking at the cog icon at the toolbar
-(bottom left, 6th icon) and add the following line at the end of the file,
-and then save it. You might need to restart your editor.
-
-```
-config.transitions = false
-```
-
-### Hide files from the file list
-
-If you would like to hide files or whole folder from the left side bar list,
-open your configuration by clicking at the cog icon at the toolbar
-(bottom left sixth icon) and add the followline at the end of the file and
-save it. This hides all the files that start with a dot, and all the `.info`
-files. You might need to restart your editor.
-
-```
-config.ignore_files = {"^%.", "%.info$"}
-```
-
-You can add as many rules as you want in there, to hide files or
-folders, as you like.

--- State is a string of bytes, where the count of bytes represents the depth
--- of the subsyntax we are currently in. Each individual byte represents the
--- index of the pattern for the current subsyntax in relation to its parent
--- syntax. Using a string of bytes allows us to have as many subsyntaxes as
--- bytes can be stored on a string while keeping some level of performance in
--- comparison to a Lua table. The only limitation is that a syntax would not
--- be able to contain more than 255 patterns.
---
--- Lets say a state contains 2 bytes byte #1 with value `3` and byte #2 with
--- a value of `5`. This would mean that on the parent syntax at index `3` a
--- pattern subsyntax that matched current text was found, then inside that
--- subsyntax another subsyntax pattern at index `5` that matched current text
--- was also found.
 
--- Calling `push_subsyntax` appends the current subsyntax pattern index to the
--- state and increases the stack depth. Calling `pop_subsyntax` clears the
--- last appended subsyntax and decreases the stack.

--- This will match / and will look ahead for something that looks like a regex.

---         cause "Catastrophic Backtracking" in some cases.
---
--- [^\\[\/]++ will match anything that's isn't an escape, a start of character
---           class or an end of pattern, without backtracking (the second +).
---
--- \\. will match anything that's escaped.
---
--- \[(?:[^\\\]++]|\\.)*+\] will match character classes.
---
--- /[gmiyuvsd]*\s*[\n,;\)\]\}\.]) will match the end of pattern delimiter, optionally
