Lite XL v2 for AmigaOS 4.1 FE

Lite XL is a lightweight text editor written in Lua.

The port is not perfect and might has issues here and there. For example the filesystem notifications are not working yet. So when you make changes at a project folder those will not be reflected in Lite XL automatically.

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.

New features against Lite XL v1

  • Faster file scrolling
  • Faster switch between tabs
  • Reposition tabs at the side or at the bottom of other tabs, making multiple columns/rows of opened files
  • Multiple cursor editing
  • Better font manipulation and appearance
  • Faster transitions

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 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

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

The Lite XL that you are using on AmigaOS 4 is based on version 2.0.4 and not the latest version that is available by the development team. This means that some of the latest plugins might 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 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.

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-xl Make sure the file ends with one blank line.

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

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

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

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

smallclock It adds a small clock at the bottom right corner.

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 (CTRL+SHIFT+R)

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 (CTRL+SHIFT+R)

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

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

I would like to thank

  • IconDesigner for the proper glow icons that are included in the release
  • Capehill for his tireless work on SDL port
  • Michael Trebilcock for his port on liblua
  • Lite XL original team for being helpful and providing info

Without all the above Lite XL would not be possible
