I rewrote the terminal driver so that it now uses VT100 for output. With this it is now possible that applications can control their terminal window by sending escaped commands.

This also allowed me to finally separate the shell implementation from the terminal itself (it was basically a "built-in shell" before). The shell is now found in gosh - the Ghost shell. This shell is still work-in-progress but will soon be enriched with various features.

And what you see in the screenshot is just a little playing around - I ported the Duktape JavaScript interpreter and let it execute a little script. I have some plans on using this as a replacement for what bash etc. usually do, but this is just an idea for now.

Nice work.

Thanks. My intent is not making anyone jealous, but making them more interested and try harder to achieve their own goals

You are my day to day inspiration.

It's working. I hope that some time in the future my own Tupai OS can be closer to what Ghost is.

I'm happy to hear that ^-^

Don't give up. It's a long hard road but it's full of rewarding moments

Through until getting to his stage there is nothing hard until ACPI, HPET, implementing Cairo and VM86. Except if it has implementation of USB; then I will be jealous . I don't see anything USB on his repository btw.

Nice!

Why do some .py files have blue pad icon and some of them paper icon?
Does it support multiple filesystems (for example FAT16 hard drive partitions next to EXT2 hard drive partitions)?

I guess these files have the "executable" permission ("chmod +x file.py")? Is it right, klange?

Nothing hard... I'm waiting to see your OS with multicore support, an advanced window server, a proper filesystem, a whole lot of self-written libc, a proper custom GCC, a shell, a GUI terminal driver that actually works as such and is not just implemented in the window server, etc.. It is not just about writing a kernel, it's about designing an entire system and also implementing it.

It's considerably harder to design a good userspace system than just implementing drivers for things that usually have very good specifications and for which you have many many sources that already implement it/had problems with implementing it/found solutions.

You clearly have no idea.

Yep. A handful of modules in the Python standard library are meant to be usable directly, and I took the naïve approach when selecting an icon.

While I'm here: I made a new drawing app to replace the old one in my OS. I spent far too much time building the color selector using mesh patterns in Cairo. It's based on the GTK+ color picker that I'm used to using in Inkscape.

(Click to enlarge.)
I tested my OS on one of my old test PCs (single Pentium 4, ~2 GHz I'm not exactly sure how fast) and I concluded I need major performance improvements for older CPUs as I got used to testing on my laptop only.
Meanwhile, on my other test PC, it doesn't even boot.

Yeah, you do have speed problems - those raindrops seem to take an eternity to flow down the window

No, seriously I need to improve my graphics performance and decrease the amount of redraws I do.
