Lite XL for AmigaOS 4.1 FE

Lite XL is a lightweight text editor written in Lua.


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 AmigaOS 4.1 FE version uses the executable folder, but if you want to ovveride it, create an ENV variable named HOME and set there your path.

You can check if there is one already set by executing the following command in a shell


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/"



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


The Lite XL that you are using on AmigaOS 4 is based on version 1.16.12 and not the latest version that is available by the development team. This means that the latest plugins are not working at all or need some modifications to work.

To make it easier for you, I gathered some of the plugins that are working well, and I included them at the 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.

The included plugins are the following:

autoinsert Automatically inserts closing brackets and quotes. Also allows selected text to be wrapped with brackets or quotes.

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

colorpreview Underlays color values (eg. #ff00ff or rgb(255, 0, 255)) with their resultant color.

eofnewline Make sure the file ends with one blank line.

ephemeraldocviews 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

hidelinenumbers Hides the line numbers on the left of documents

indentguide Adds indent guides

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

memoryusage Show memory usage in the status view

minimap Shows a minimap on the right-hand side of the docview.

motiontrail Adds a motion-trail to the caret

navigate Allows moving back and forward between document positions, reducing the amount of scrolling

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.

selectionhighlight Highlights regions of code that match the current selection

todotreeview Todo tree viewer for annotations in code like TODO, BUG, FIX, IMPROVEMENT

Tips and tricks


If you want to disable the transitions and make the scrolling a little faster, 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.

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.

config.ignore_files = {"^%.", "$"}

You can add as many rules as you want in there, to hide fore files or folders, as you like.

Know issues

[] - 2022-01-11


  • Added config.scroll_past_end that when its true lets the user scroll further than the end of the file. By default is set to true.
  • Added "SDL_RENDERER_ACCELERATED" and "SDL_RENDERER_PRESENTVSYNC" on SDL_CreateRenderer() since this reduces the CPU usage when the user scrolls and seems to work pretty good on my systems (X5000, A1222 and microAmigaOne). This is exeprimental. If this brings problems on your system, you can disable them using SDL ENV variable, like below: setenv SDL_RENDER_VSYNC 0 setenv SDL_RENDER_DRIVER "software"
  • Added plugins and color schemas in addons folder and information at the README_OS4 file (#10)


  • Compiled Lite XL with gcc 8.4.0

[] - 2022-01-04


  • Fixed a problem introduced in previous version when LiteXL was executed from the root path of a partition or from ram disk (#13)

[] - 2022-01-03


  • Changed the Gfx memory leak solution to a fix that was applied by the editor development team on Lua scripts at a later version. Less custom code for AmigaOS 4 port.
  • Now, when return from fullscreen, there is no extra header visible at the top of the window content


  • Fixed the assertion error and crash when the window is resized (#2)
  • Fixed the resolution on fullscreen toggle to be like the workbench (#4)
  • Fixed loading the current folder from terminal using the dot, like lite . or without it (#3)

  • Fixed the Gfx memory leak. Now LiteXL frees the reserved memory from the gfx card.

[] - 2021-12-29


  • Compiled with an experimental version of the latest Anti-Grain Geometry library. This is might have issues and crash LiteXL

[] - 2021-12-26


  • Added Amiga version. This version of LiteXL is based on v1.16.12 source code which will not change. I will use the fourth digit to distinguish different AmigaOS 4 releases, until a new port of the latest available source (v2.x) is made.


  • The keyboard shortcuts are now working


  • Now the HOME ENV variable is optional. If this is not set, the LiteXL folder will be used to create user's .config folder
