Hello everyone, The final version of the next LuaRT release will be available soon. Contrary to what I had planned, this version includes numerous internal...

You can achieve the same behaviour using the async function syntax with LuaRT preprocessor :

--! luart-extensions

async function greet(name)
    print("Hello", name)
    sleep(1000)
    print("Goodbye", name)
end

-- Now each call creates a new Task
greet("Alice")  -- Task 1
greet("Bob")    -- Task 2

I have updated the post with the portable versions :

Unpack the choosen portable zip file anywhere (even on a USB key)
Open a console and go to the folder where you have unpack the zip file
Execute the setup.bat file to make luaRT toolchain available

Very sorry, but the portable LuaRT-2.2.0-x64.zip does not pass the firewall security check, I can't download it at all, maybe due to the .bat inside or some other reason...
"Threat found: Sandbox Suspicious"
Any other option?

Samir

Work computers are very secure and do not tolerate potentially risky files (especially those that are not widely known).
The simplest solution would be to compile the source code (if the work computer even allows the use of a compiler).

Source files should be available this weekend on gitHub

steve64

If needed I will do so. So far I had no problems with LuaRT ZIPs and EXEs...

ruby

nice. but what are those xx-static.dll files? static linked dynamic link lib? never heard such things

Samir

It was introduced with static interpreters. They are Lua binary modules that can be linked statically to a single exe.
(This is impossible in standard Lua as all binary modules depend on the Lua DLL)

ruby

there's always some new tech to learn.

this reminds me that lite-xl also can link other .dll without lua.dll. never understand.

Lite XL uses Lua's convention for these libraries, but extends the convention to support statically-linked Lua in Lite XL.

Samir

Yes I think it's the same technique that was used in LiteXL

Btw, any feedback on this new version ? Did some one try the new preprocessor (examples have all been updated with this new syntax extensions) ? Did you someone use the capture module ?

I need some feedback to publish LuaRT 2.2.0 officially on GitHub 😉

ruby

I tried some examples including capture.
I think everything is ok.

import ui, capture

this does not look like lua any more ...
it is hard to judge whether DSL is good or not though

Samir

Yes it dont look Lua anymore I agree and that's why it's optional you can just use local ui = require "ui" as well.

But once you taste it, it's very hard to go back I must admit 😅

Samir

Hi all,

LuaRT 2.2.0 is now officially out. Go check the documentation for the new features.
Check the syntax extensions tutorial too : [Login to see the link]

Thank you all, hope you will appreciate this release.

Samir

Some users are reporting installation issue (when launching the installer from the zip file opened in an explorer Window). Try to extract it (on the Desktop for example), then run the installer.

steve64

I have exactly that problem, even after extractng the EXE from the ZIP and unbloking it.

steve64

I was able to rebuild LuaRT-master from github.
Now the luart.exe, rtc.exe and wrtc.exe under C:/LuaRT-master/bin work and report version 2.2.0
But I do not know how to build/run the new LuaRT Studio.
I already tried to rebuld it using C:\LuaRT-master\tools\LuaRT-Studio\build\LuaRT Studio.bat
when running the obtained "LuaRT Studio.exe" it asks for lua51.dll or shows an error dialog with uncaught exception

Samir

Just go the the src/core folder and type :
nmake buildtools

Then you will be able to use LuaRT studio with LuaRT 2.2.0

steve64

I tried and got a certificate error as follows;

C>nmake buildtools

Dont worry this does not means the building failed, just that the exe compiled can't be signed with a certificate. You can use LuaRT Studio now

steve64

ok, thanks, in fact it seems to work anyway...
but now I'm getting errors when compiing with rtc (with previous LuaRT version this worked):
