Software News : LiteXL for AmigaOS 4 released

Posted by walkero on 2021/12/29 14:20:00 (1519 reads) News by the same author

The first public version of LiteXL editor just released. This is a lightweight text editor written in Lua and SDL, with features like Syntax Highlight, custom plugins, color themes etc. This is the first port based on the v1.16.12 source code of the program.

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.

LiteXL for AmigaOS 4 is still experimental and there are some known issues, but it is quite usable. It is recommended to use it on a fast AmigaOne, although it was tested on microAmiga1 and works pretty good, but slow.

Please, read the enclosed README_OS4.md file before run it.

You can download the firsts public version from https://git.walkero.gr/walkero/lite-xl/releases

The only 2 things i miss right from the start: clicking on an open file gadget didn't bring us ASL requester. And the scrollbar is pretty "tiny" and almost invisbly. if those parts can be replaced on reaction/mui ones that will be very nice! But app is good!

Not too shy to talk Joined: 11/29/2006 From: Comments: 474	Thanks for the Port! Thanks for bringing OS4 a new editor for us to play with. It works pretty well for an early release. I think CodeBench provides the most complete, feature-rich editor for coding, and it basically satisfies all my wants. However, your Lite XL editor does have one nice feature that is missing in CodeBench, namely, UTF-8 support. Ever since Hollywood added UTF-8 support, I've been wanting an editor on Amiga that would also support it. I'm sure I'll always use CodeBench for big projects, but Lite XL (if it matures a bit more) would be a really nice alternative for small projects.

A new version is released with a fix on the Gfx memory leak. You can download it at https://git.walkero.gr/walkero/lite-xl/releases/tag/v1.16.12.4 @PEB LiteXL is not intended to be an alternative to Codebench in any way. Codebench is one of the best IDEs that are available in our OS. I wish we will see a new release soon with bug fixes and faster scrolling.

Also wanted to say a massive thanks for your work on this, I've been following your progress and it's an awesome addition to my OS4 development environment. Been giving it a try with my setcmd project as I port it to 68k, and I'm really enjoying using it even in this early state. Fantastic work!

Have you tried to delete/rename the .config folder before you start LiteXL, so that a new one is created? I am trying to reproduce it here on any machine and I can't really get that error.

Plrease verefy the file "error.txt" n the idrectory RAM Dis:iteXL/.confg/lte-xl" and then in the shell the same error as for others ps. That bug with comments on amigans.net is still here: for first it's an unformatted mess, then need to press edit, and choose "Auto wrap lines", and only then formattng are fine.

Through noted now that scrolling is pretty slow. if I open README.md grab the scrollbar and try to move the page then it really slow and unresponsive :( Even pure move by mouse wheel takes 100% CPU loading.

Site Builder Joined: 12/02/2006 From: Athens/Dublin Comments: 1657	Re: compostng @kas1e Yeah, it is SDL2. I get the CPU to 100% on my system as well, but I wouldn't say that it is unresponsive. It depends of course what else are you running at the same time.

The editor on my Sam460ex seems to be quite heavy to manage, a bit sluggish and slow, sometimes it freezes for a split second (e.g. when selected chunk of text with the mouse), but it works.

I am sure there are ways to optimize it. This is a learning journey for me as well. So, if you have any recommendations, feel free to tell me so. @capehill Quote: Could you try to request VSYNC when calling SDL_CreateRenderer I will try it and see if it makes any difference. Quote: 2) Is liblua build compiled with -O2/3? I have to check this out as well. I am not sure, to be honest. Good point.

I need to test how it works on my A1222 and microAmiga1 and see if it fails or not. If I am not wrong both of them are able to be set in ENV variables, right? In case someone would to test it on his system. At https://wiki.libsdl.org/SDL_RendererFlags there is the following mention Quote: Note that providing no flags gives priority to available SDL_RENDERER_ACCELERATED renderers. Is this the case with the AmigaOS 4 version or not? Quote: 2) Is liblua build compiled with -O2/3? It is compiled with -O2. I will compile it again with -O3 and see if it makes any difference.

Just can't stay away Joined: 07/14/2007 From: Lothric Comments: 1670	Re: compostng @walkero User may try to override the default renderer by: setenv SDL_RENDER_DRIVER "software" ; Might be good for WinUAE, no need for CompositePatch setenv SDL_RENDER_DRIVER "compositing" setenv SDL_RENDER_DRIVER "opengl" setenv SDL_RENDER_DRIVER "opengles2" So technically one can try Warp3DNova by choosing "opengles2". But I don't think it matters. Texture upload from RAM to VRAM will be done by the CPU in anyway when there is no DMA support. How about X1000 users, don't they have the DMA? Quote: Is this the case with the AmigaOS 4 version or not? Yes, it should be. I think compositing comes first.

Do you believe there are going to be issues with any kind of hardware? If I get it right, and please correct me, that's the default anyway, so it wouldn't make any serious problems, right?

Do you believe there are going to be issues with any kind of hardware? Should be safe but also unnecessary. I think WinUAE users will get a blank window if they don't run PatchCompositeTags, or force SW rendering using setenv, but that's normal. By the way, here is the logic: https://github.com/AmigaPorts/SDL/blob ... /render/SDL_render.c#L819 If there is no hint then flag match is used.

Or should I leave it as it is and if someone would like to enable VSync to do it using ENV variables? Sorry if I ask the same things again and again, but I am not familiar with SDL

Just can't stay away Joined: 07/14/2007 From: Lothric Comments: 1670	Re: compostng @walkero Yes, overriding both VSYNC and render driver should be still possible because these are checked before trying to match the flags. You can test it, try requesting SDL_RENDERER_ACCELERATED \| SDL_RENDERER_PRESENTVSYNC from code but then force VSYNC off with: setenv SDL_RENDER_VSYNC 0 Perhaps you can notice difference in the CPU load?
