Gideros 2022.1 Released

hgy29 · January 2022

@keszegh, I double checked wintab setting, and I am sorry to tell that I didn't add it in the right place. I mistakenly add it in an inner 'if', where it is never called. This is easy to fix, and I think a 2022.1.1 will come very soon given the amount of things that went wrong in this version.
Thanks to all for your reports.

keszegh · January 2022

@hgy29, no problem and thanks for the nice new update, the quirks hopefully will be gone soon.

@hgy29 how do I use my beta ImGui dll? I have it in plugins folder, but when I call

require "ImGui_pre_buid"

Im getting an error:

[string "luabinding/compatibility.lua"]:79: Module ImGui_pre_buid not found
stack traceback:
	[string "luabinding/compatibility.lua"]:79: in function require
	main.lua:1: in function <main.lua:1>

Oh, oops, I have a typo in require function

rrraptor · January 2022

@hgy29 I found that luau provides new type: "vector" and have a C api for that:

lua_pushvector(L, x, y, z [, w]) // depends on LUA_VECTOR_SIZE in luaconf.cpp
float* lua_tovector(lua_State* L, int idx)
float* luaL_checkvector(lua_State* L, int narg)
float* luaL_optvector(lua_State* L, int narg, const float* def)
bool lua_isvector(lua_State* L, int idx)

and a type enum:

LUA_TVECTOR

But as far as I can tell there is no way to use it from lua side. I wonder is it some sort of beta feature? Can be very usefull with imgui sliders

Here is the implementation of some methods: https://github.com/Roblox/luau/blob/32c39e2162b7539fd3233215df3dea23421c0503/tests/Conformance.test.cpp#L67

hgy29 · January 2022

Yes, this seems interesting for 3D APIs, but I wonder how the language uses them, maybe through a specific Vector type ?

Hi everyone, I want to give some feedback for Gideros 2022.1 luau version.
Thanks to hgy29, rrraptor(imgui master) and sinistersoft for the new Gideros 2022.1 and older versions. plus Paul,Nicke,antix,keszegh,mokalux and other Giderans for their contributions. I have been following you guyz for a long time but my English skills is not enough sometimes and I am not good coder, just stubborn and couldn't produce serious project so far. If I am available for some reasons I will try to produce a project in the future.

I tested Gideros 2022.1 on System information:
Wine build: wine-7.0-rc5
Platform: x86_64
Version: Windows 7
Host system: Linux
Host version: 5.16.0-arch1-1

The most of the examples work fine but the ones that don't work are below.
3D Horse
3D Animation
benchmarkFunctions
and Addons

Some of them have shader issues, I will add some comparison screenshots.
3D Instancing
VR Oculus
3D Collisions

Luau does not like string methods (string.sub, string.dump, string.find etc.) and dataSaver implementation.

Before I have tried to convert a codepen-io javascript example with rrraptor fastnoise plugin, works on Linux Gideros 2021.11 build but The Gideros 2022.1 gives wine-debug output(pls look at attached files)

Player crashed without any output for some old examples(works well with 2021.11). Need to guide old bit plugin conversion changes.

By the way if someone want to try Gideros 2022.1 on wine. You should load corefonts by "winetricks corefonts" command on linux side. Because Qt6 and Scintilla font rendering have some issues. You should change GiderosStudio to dark theme for better fonts.

Thanks again hgy29 for the great great jobs.

hito9 · January 2022

Edit: My attached files did not show up, what should i do? and my entry reposted again?

in windows desktop export i just have a white screen whereas in gideros player my app runs mostly fine.

Some minor issues:
- gideros studio when you click a tab you also have to click the code to get the cursor moving

quick fix: when you click ctrl+tab to switch code click tab again to be able to type.

PS: glad to hear gideros runs on linux, thank you (at)hito9

I did a quck test of vector math:

TEST = 1000000
function runTest(VecFunc)
	local vec1 = VecFunc(1, 2, 3)
	local vec2 = VecFunc(2, 1, 1)
 
	local ts = os.clock()
	for i = 1, TEST do 
		local v = vec1 + vec2
		v = vec1 - vec2
		v = vec1 / 2
		v = vec1 / vec2
		v = vec1.Magnitude
		v = vec1:Dot(vec2)
		v = vec1['Dot'](vec2, vec1)
	end
	print(os.clock() - ts)
end
 
runTest(vector) -- Luau native vector 
runTest(vec3) -- My implementation in luau

Native: around 0.2 seconds (for 1m iterations!)
Luau: around 2.1 seconds

So, I think it is worth to implement it somehow?)

block comment/uncomment as in zbs would be cool, i'm quite used to it.

I thought we had it already, but it seems no. What would be the shortcuts for those ?

ctrl+U toggles block comment/uncomment (i think it comments if there is at least one line with -- somewhere in front (perhaps with some spaces before) and uncomments otherwise)

thanka

hgy29 · January 2022

@keszegh, thanks. Also does it add the '--' at the very beginning of each line or after the indentation ?

rrraptor · January 2022

There is some new function compared to Lua5.3:

table:
	clear, isfrozen, find, create, freeze
--------
math:
	round, clamp, noise, sign
--------
string:
	split

And comared to Gideros Lua 5.1:

table
	clear, pack, move, isfrozen, unpack, find, create, freeze
--------
math
	round, clamp, noise, sign
--------
string
	split, pack, packsize, unpack

at the beginning of the lines.

ctrl+U is already taken:
• Control - U : Make all lowercase
• Control - Shift - U : Make all UPPERCASE

and that works in new gideros 2022.1
https://wiki.gideros.rocks/index.php/Getting_Started#General_key_bindings

I would prefer the Android Studio way, I think it is ctrl + / on the numpad

that is what is especially annoying for me, whenever i press it i have to undo (if i notice that i've messed up everything, otherwise even worse).

EDIT: i wonder how many people use make lowercase/uppercase buttons, of course i don't wish to ruin their experience but it seems like a marginal usability thing (compared to mass comment/uncomment which i e.g. use regularly), perhaps it is enough to have it in the menu.

MoKaLux · January 2022

let's see what others think and what hgy29 will do

We will make sacrifices for the benefit of glorious new gideros

Definitely, I would implement the four component vector to support 3D games (with quaternion). Vectors of 4 floats could also be useful to convey colors

@hgy29 If possible can you add something like "LoadUsersKeyPreferencesFromFile();" where GiderosStudio.ini file in crossplatform path. Most programmers cannot change their old habits.

It turns out that Ctrl+U is a scintilla default shortcut, so I decided to leave it as is and define block comment as Ctrl+Shift+C ('C' for comment).
But I also implemented @hito9 suggestion and those will be overridable through a ini file, such as:

[main]
actionBlock_un_comment=Ctrl+U
 
[scintilla]
Ctrl+U=0
Ctrl+Shift+U=0

It shall be called keymap.ini and located in Gideros user folder (one level above user plugin folder). It will divided into two sections: 'main' for the Studio menu actions, and 'scintilla' for Scintilla specific shortcuts.

@hgy29 Im trying to recompile debug version of gideros player, but Im getting error:

lua.hpp: No such file or directory

all over the place

I assume that it must bu included by qt in INCLUDEPATH somewhere here:

But

LUA_INCLUDE = ../luau/VM/include ../luau/VM/src

which does not exists.
Do I need to compile Luau myself?

keszegh · January 2022

sorry @hgy29 for somehow being offtopic, i remember raising in some topic the question of loading files to memory asynchronously. i don't remember the answer. i think it is not possible, but is there a chance that it will be in the future?

EDIT: i guess one can workaround this by reading in chunks as in http://lua-users.org/wiki/ReadDefinedChunks
yet i don't see a workaround for writing a file asynchronously.

Yes, you need to compile luau yourself, as part of the player. Run

make -f scripts/Makefile.gid prep.repo

to setup the luau submodule from a MSYS2 terminal (you'll need git).

lua is basiclly single threaded, and Gideros too. It may be easier to deal with files asynchronously than anything else, but making sure every critical part is protected against concurrent modifications is still complex. I hope we'll reach the point where Gideros is fully multhread compatible though, but I can't give forecasts on this.

Ok, now after compiling:
openal, xmp, libgvfs, pystring, luau, libgid, libgideros
I still cant compile player in debug mode

hgy29 · January 2022

Yes, you also need to run

make -f scripts/Makefile.gif versioning

Yeah, compiling gideros has become much more difficult since QT6 and Luau...

rrraptor · January 2022

Errors after errors, and now Im stuck again

Solved: copy Qt\6.2.2\mingw_64\plugins folder into working directory of the player

rrraptor · January 2022

It is working, finaly!
BUT! I cant load my dll

[string "luabinding/compatibility.lua"]:79: Module ImGui_pre_build not found
stack traceback:
	[string "luabinding/compatibility.lua"]:79: in function require
	main.lua:9: in function <main.lua:1>

package.preload:
	gyroscope
	geolocation
	accelerometer
package.loaded:
	string
	table
	bit
	io
	bit32

hgy29 · January 2022

Hmm, did you link your dll with the new Sdk ? Also maybe you didn't notice but the binding code have changed a bit with the switch to luau

SinisterSoft · January 2022

@rrraptor Based on your experience, can you update this: https://wiki.giderosmobile.com/index.php/Compiling_Gideros_Source
