is it true? Just written some module in v.

v also cloned from others.

If the software will be realeased than it could cover more and more people. So Make a STABLE release for Customer

If you create a file called /bin/loop with the following contents:

#!/bin/loop

The VINIX kernel will infinitely recurse in the userland.start_program function, until it eventually runs out of stack space and panics.

The way Linux deals with this case is by keeping track of the recursion depth, and setting errno = ELOOP and returning if the arbitrary max depth is reached (I believe the depth is 4 on linux, but don't quote me on that).

Description

After the successful boot, whenever I press the "tab" key from the keyboard, Vinix kernel will panic with a page fault. Build version: Nightly-2022-07-16

Description

The system simply stops when pressed keys like '(', ')', '.', ',', TAB, BACKSPACE in nano or vim

I was trying to join the discord chat, the URL to join the server has expired.

The distro will not build on raspberry pi so there is no way to build the kernel.

I already mentioned it in the discord, but it would be nice to add more than one keyboard layout (Something like the loadkeys command in Linux).
As far as I know @streaksu is already working on it, but I wanted to make an issue in case someone wants to comment something.

this makes nano pretty much unusable

I am trying to build vinix using make distro and it keeps failing. I have been able to successfully build vinix using make. Here is a screenshot of the error that I get when I run make distro

Panic in Virtualbox with Muticore CPUs ,even single core

I was wondering because I was going to make a file downloader for vinix. Maybe once it works we could add it to vinix.

I'm not sure if this is something specific to my system or not, but I had to bump the qemu memory limit in the Makefile to 4G but after that it booted (though bash is complaining about no job control). I run a somewhat out of date void linux install, if that makes any difference.

There's also an issue that the OS's console doesn't show any sign of the panic - I had to check the terminal I ran make run-kvm in to find out it was panicked. I managed to trigger another panic later (I hit up in bash to get the last entered line. Error was: array.get: index out of range (i == 72, a.len == 58)) which did show the panic info, so this might be some edge-case or something.

Also, I just want to say, this is the first OS I've found written in one of these newer languages that actually builds and runs. Best of all I didn't have to deal with the whole "build your own cross-compilation setup by hand because it needs a specific version of GCC" task only to be greeted with cryptic compile errors that wind up being broken code due to their compiler/stdlib internals changing. I cannot begin to convey my awe at this. Extremely well done.

/root dir does not exist

This system is very cool but I still don't know how it works from the ground up. Do you foresee the creation of some tutorial on this topic. Something like https://os.phil-opp.com/ only in V ?
I look forward to your reply 😊

For the most part a UK layout keyboard works on Vinix, but certain keys will trigger a panic. For example, when typing a pipe character:

V panic: array.get: index out of range (i == 86, a.len == 58)
v hash: bfcf5b1

I suggest for all keys that cannot be mapped, that U+FFFD � REPLACEMENT CHARACTER is emitted.

I just pulled the repo today (upgrade mlibc - d6bd129) and tried to build on an Arch based distro of Linux. I had the same errors in the wget subdir when trying to build with both clang-12.0.1 and gcc-11.1.0:

I tried to just remove the wget directory and maybe get things built that way, but I ran into some similar errors with another package. Not sure why this is happening, but it is a bit of a show stopper :)

Any suggestions?

For this, we need to have a pre-built x86_64-vos-gcc, to prevent timing out the CIs (and also make it a lot faster). One CI will build x86_64-vos-gcc, and then publish it in releases (if the commit has a tag).

List of things we should test:

• Formatting (v fmt -verify)
• Distro (make distro, and then publish ./build/tools/host-gcc/bin/x86_64-vos-gcc for use by subsequent jobs)
• Building (make)
• Running (make run)

when i try make distro it gives me this error ../../../3rdparty/glib/subprojects/libffi/src/meson.build:71:2: ERROR: Problem encountered: Unsupported pair: system "vinix", cpu family "x86_64"

Hi there! I'm using VINIX to learn how to write an operating system, and in the process of porting the event subsystem into my own OS I spotted a bit of a strange calling convention in the event.v file.

On line 79, there's a C function declared called event__trigger, which is then called on line 94. I believe this is actually calling the V function event.trigger from the event module, however it is doing it using the calling conventions used for calling into C code for some reason. It gets away with it because of the way Vlang clobbers function names (module.function -> module__function) making it actually a "valid" call, but this exposure of V's internals is potentially unstable so I thought I'd bring it to your attention.

If there's an actual reason behind this, or if I'm misunderstanding something, I'm happy to be corrected!

How to write a windows kernel driver hook ssdt table with vt-x ept page hide use vlang

I started seeing this recently, whenever I do a git pull:

error: Your local changes to the following files would be overwritten by merge:
        kernel/blob.patch
Please commit your changes or stash them before you merge.

I have not modified that file, myself, so it must be happening during make distro or make operations.
I have to do a git restore on the file before git pull works.

Error when characters reach the end of the screen:

It won't let you press enter during the save process in nano.

I was using GCC, V, and G++ and they all hang when trying to compile the scripts that are on the system already. I tried canceling them and GCC and G++ cause a page fault on CPU 2, but V just hangs and shows the ^C as many times as you type it.

exit

It just restarts bash.

I was messing around and found this weird bug.

The file 000000 is a bug caused by v and I don't know if this is a v or vinix problem.

Been a while since I tried to build vinix, and now on a new machine, so I started from scratch... cloned the source, installed necessary packages, typed make distro-base (which took a while, but finished successfully), then typed make all, which ended quickly with

* building package: kernel
* building host package: v
curl: (3) URL using bad/illegal format or missing URL
make: *** [GNUmakefile:9: all] Error 3

There are only 2 curl commands in the GNUmakefile, one to download jinx, and one to grab OVMF files. Since it didn't create an ovmf dir for the 2nd, it seems like it would have failed on the jinx curl... but I have jinx locally, and it just got created. So what is it complaining about?

Right after booting the ISO from the releases page I cleared the screen using Ctrl+L and typed "vim", and the console started spamming V panics.

I like the idea of a V based OS. For branding, why don't you use a fox (inspired) logo? My reason for saying this is that "vos" is the dutch word for Fox.

I might not be the best person to contribute a logo, but maybe someone else can run with this idea and make something cool.

Hi, respectfully i suggest to consider fully distribute the project under non-gpl licenses as it's demonstrated in project's like tensor flow (almost 3/4 AI projects are licensed in MIT-like licenses) it attract coders looking to get rid off viral clauses (as did tensorflow with R-based ML), while choosing for some license in Open Source community driven projects is seen with ideology or fear, other faces it with the practical issues derived from each license conditions, GPL is often considered as opesource savior as it prevents the IP being "stolen" by an commercial or rival actor, but actually it also kick off developers which just want some building blocks for his project's, mature developers understand how important it's for code life cycle to return to the community the improvements or corrections privately made, original developers will ever keep the advantage of the original know how and of being the community hub, while newcomers doesn't get discouraged to build a commercial product on top. Un mature developers will try to steal the code anyway with an fork (from gpl) or with an more elaborate "full" re-write with "own" IP.

Please don't see it ideologically, watch a what license has dominated most popular opensouce projects from last 10 years: non-gpl sound success: tensorflow, python, pytorch, node.js it's quite unusual seeing an new GitHub project based on python,node.js,swift even kotlin using gpl-like licenses.

I see big enthusiasm around V lang, but GPL IMHO kicked away more adopters than enthusiast it drives into.

Hello there. I just wanted to ask why not musl.

Can you build a screen reader for this system, or port orca from linux? Please make this system accessible to orca if you're just going to port orca over to vinix. Thanks
