Minetest Forums

Measuring the CPU load caused by mods is not that easy. I've struggled with this for a long time. I put a lot of effort into this, especially for techage. CPU load is caused by many things: - Running code via `minetest.register_globalstep` - Running code via `minetest.register_abm` - Running code vi...

Update

vm16 is now in a usable condition. Further improvements are planned.
The second mod, which uses vm16 is Beduino
A video to Beduino is on YT

Beduino, a new computer mod: https://youtu.be/Dbn19YcltTk

Hast du einen Quad-Core und zeigt das Diagramm die Auslastung über alle Cores?
Dann wären das nämlich bereits 100% für einen Core (Minetest Mods können nur einen Core nutzen)

1) Wind Turbine The wind turbine says "No nacelle attached" ("Gondel nicht angeschlossen"), even if it is attached. I tried different orientations, but my first guess was right: The parts with the big dark circle go together. I just left the plant as is (with error and no blades...

Update New features and changes: Import of C and ASM files added for larger programs Further C examples added to the file server Standard library function added (stdio, mem, string, math) Started to write a "Language Reference" manual on GitHub Improve debugger with step-in and step-out b...

not this... more pdp-13 or vm 16. just that with normal gui apps, user management, commandline and very big extensablilty (ability to create apps - both gui and cli, api for other mods to create app entrys... etc etc). like linux generally. just that it exists so i left... vm16 is just the virtual ...

and also - someone knows if its possible to embed other folders to init.lua ? like /games /root or /misc ? This is possible by accepting that this mod becomes insecure and has to be added to the list of 'secure.trusted_mods'. E. g. PDP-13 is a mod, with provides a file system for each computer.

ta4 concentrator don't connect with distributor:

I know, but that's not a bug. The concentrator only connects to other tubes. The concentrator is a "networks.junction" block. Like other junctions, it will not connect to "secondary" blocks like the distributor.

Update

Compiler now supports:

• one-dimensional arrays
• pointers
• strings and chars
• constants

This largely completes the range of functions.

Update

Inline assembler added to compiler and debugger.

Ah, ok. The CPU is a self made 16 bit VM without any template. It is as simple as possible. Simple to implement and simple to be programmed in assembler. Though since you mentioned ISA it's worth asking if there is a bus standard for your architecture as well, comparable to ISA/PCI? It has no bus st...

So i'm not completely off-topic: what kind of ISA and ASM syntax is used in the mod?

The assembler follows the Intel syntax. See manual.

But what is ISA? I only know ISA bus :)

You can have syntax highlighting with the `hypertext` formspec element. Unfortunately, this is not possible inside a textarea[...] field, I guess There's some misunderstanding here. hypertext is a powerful alternative to textarea , it is not meant to be used inside textarea . hypertext is, actually...

Update

• The Assembler mode is reactivated again. The controller/CPU can now be programmed in assembler and in a C-like language.
• More classic looking blocks with 16x16 textures are added for programmer and server. These can be used alternatively.

Update Version 3.3 is available in GitHub : - Mod completely restructured - Programmer block (notebook) with the development environment (compiler, debugger, file browser) added - File server block added - Demo CPU/controller adapted to the programmer - Many compiler and debugger improvements The m...

This mod looks cool. Would it be possible to integrate it with Mesecons?

Yes, sure.

(Almost) High Level Language for Minetest (work in progress) C like language (so far the only data type is a machine word ) Other language flavors are also possible Symbolic debugger with breakpoints and variables The idea is to provide a PLC like "programming station" which contains comp...

Thanks Chem871 :)

You must add inv:set_stack("main", placer:get_wield_index(), stack) to write back the data

v2.6 is available with breakpoint support and further CPU improvements https://github.com/joe7575/vm16/blob/master/screenshot.png?raw=true The turquoise line is the position with the next instruction to be executed The yellow address (000A) is the breakpoint Hint: Because of the breakpoint support,...

rip-relative addressing doesn't seem to work nicely with labels. Ie. jmp +mylabel jumps to PC + location of mylabel, not PC + location of mylabel - current location.

Thanks for the hint, the bug is fixed with the new version 2.5

Mit MT 5.5 sollte es gehen. Ich habe es aber noch nicht getestet, bin auch noch bei v5.4.1
