Re: raylib headers

who was the genius bright fellow, that converted a beauty .h interface into fellow garbage OOP?? genius people these days... Hey, that was me :) Good to hear, that you like my work. I have added some constructors to Raylib's structs, no OOP besides that. They are completely optional though and only...

Re: Accessing a global array with inline-ASM

Oh God, I completely forgot that you could use pointers like that. Now this is embarrassing.
Thank you

Accessing a global array with inline-ASM

Hello :) So I am trying to read a 16bit integer out of an 8bit array. Since that usually would involve some bitshifting, which the compiler doesn't optimize, I decided to do it in Assembler instead. However, I can't seem to find an easy way to access the array with an index inside a register like &q...

Re: raylib headers

Ported the rlights.h header, to port some examples that need it (namely, models_material_pbr.c). However, all I've got was a white screen. So, I tested the C example and alas, same thing. models_material_pbc.c does work for me as expected. What OpenGL version is in use for you? It should tell in th...

I changed the formatting a bit to fit with the existing examples' style. I also included the fil...

Re: raylib headers

Another one, shaders and shapes: Nice work! Take a look at the "shaders_raymarching.c" example, really amazing stuff there. @IchMagBier: do you think it will be possible to include the resources used by the examples on your repo, to have them handy? That way, upon downloading your repo, t...

Re: [Linux] Try/Catch

I'm specifically talking about @IchMagBier's post. Catching segmentation faults is very bad usually, except to do emergency bail out. Ultimately after a segfault, the only appropriate course of action is to abort the program. Because all bets are off. Well, I was in need for a "try catch"...

[Linux] Try/Catch

Hello :) I wrote this simple exception handler for Linux, which can catch segmentation faults and user defined exceptions, without terminating the program: #include "trycatch.bi" try ' // segmentation fault dim as long ptr bla *bla = 42 catch(e as Exception) if e = SEGMENTATION_FAULT then ...

Name a variable after a register

Hi! :) I have a problem with a variable named "rax" (like the x86_64 register). It all worked fine until I wrote a bit of inline assembler, that uses the actual rax register: dim as integer rax asm mov rax,42 ' This should work with the register, not the variable print rax ' 42 The bit of ...

Re: Sometimes I think the -gen gcc asm code emitter is totaly stupid :-)

With fbc -O 3:

Code: Select all

ADD_ASM:
   addss xmm0,xmm1
   ret

ADD_BASIC:
   addss xmm0, xmm1
   ret

I don't know why it still creates the ADD_BASIC function, when it's inlined anyway. But besides that, this seems to be the best solution I can think of.

Hello :) So I wanted to try out the new fbc 1.06.0 on FreeDOS 1.2. However, I can't seem to get a simple "Hello World" program working. It is crashing with a "Page fault". I am using CSDPMI7, which is working on Dosbox. The program looks like this: print "Hi" The genera...

Re: Has anyone looked into Jai?

what about breaking a call with expressions in the arguments over multiple lines? A compiler usually tokenizes the code instead of directly parsing it. Let's tokenize by hand: testfunc(1,2,3) Would create those tokens: ⋅ SYMBOL "testfunc" ⋅ OPEN PARANTHESIS ⋅ ...

Re: Has anyone looked into Jai?

This looks promising, but ... return x + y + z ; ... why do we need semicolons in 2019? I never got why a programming language would need a semicolon as its line delimiter. Either use 0x0A or simply don't use a line delimiter at all. It's not harder to parse this x=1+2 y=3+4 than this x=1+2; y=3+4; ...

JIT-Assembler (x86)

Hello I was in need of creating executable code during runtime, so I have created this little JIT-Assembler. It allows you to dynamically compile Assembler-code during runtime. This can be used to speed up a scripting language or an emulator. At the moment it only works with 8bit operations, I might...
