It might not look like much, but...
That's USB mouse.
Working.
The kind of "at last" moment after a long season of figuring things out, implementing, testing and bug-busting.




Oh, and not just in Qemu, but on real hardware as well.
That is the real money shot, since Qemu's USB is so simplified it's not even fun.

Recently ported Pango and GLib to allow me to make pretty text without manually futzing around with Freetype:

It looks really good. Can you show us what that folder icon does?

Looks better than windows rendering.

Just a simple file manager.


Also got a text editor


And OpenGL support (software):


But that's all old stuff, i bet you can find similar ones somewhere in this thread back in 2011.

Artlav: Your OS is really cool! Do you have a site, or an online repository?

Hey pcmattman, impressive. But pango doesn't actually contain fonts does it ? How do you draw the chars ?

In that example, Pango is using Freetype to read TTF fonts. It's also using Fontconfig to fall back when glyphs can't be found (eg, the main text is DejaVu Sans Mono, but the Japanese is a totally different TTF file).

I use libpangocairo to actually perform the drawing onto Cairo surfaces.

Hm, there should be something here: http://orbides.org/aprom.php
And here is the linked list of testing threads: http://forum.osdev.org/viewtopic.php?f=2&t=22667

Cute.
Font support is one of these things programmers tend to ignore completely.

I've been googling around, but can't quite figure it out - how is Pango different from Freetype?
That is, what features does it provide over the glyphs taken from FT?

I was thinking of using Freetype on it's own for my OS.

Here's my latest version. A few of the coreutils are working (the basic ones) and gcc will compile hello.c. Also truetype, cairo, ncurses work. Nano kind of runs a bit and of course the obligatory glxgears. The calculator and terminal are the first Apps for my graphics toolkit. Still plenty of bugs.

In my case, Pango is still using Freetype as a font backend to actually get glyphs to render. Pango then looks after details like layout, and it's particularly good at complex scripts and internationalisation issues (the example shows an embedded switch to RTL for non-English text).

There's a gallery of various things Pango helps with rendering on the Pango site.

EDIT: very nice, gerryg400!!

The thread doesn't look dead at all. @thehardcoreOS, so why don't you post your screenshots?

Because I am trying to enter protected mode and set up paging and then I can post some screenshots with basic text print thigy.

IMHO, this thread will never die.
