Generic update

A lot has changed since last update…​ The operating system now has:

There were a lot of changes made sort of at one moment, so that’s why I haven’t blogged about them. To have a shell you’d need a terminal driver, to type commands - a keyboard driver and to glue all of this together - an IPC mechanism of some sort. Just to get to a working shell you need to cover a lot of OSDev areas at once, which wouldn’t IMO make for a good read.

Right now my goal is to implement more shell commands, which still unfortunately won’t make for an interesting article. It’s mostly just busy work - add a "file delete" command, add a "directory create" command and so on. Nothing innovative nor worth talking about.

One thing may be interesting though regarding the shell. It would be a "find/search" command with grep-like functionality or perhaps a regex engine (?). This would actually involve some true algorithm work and thus allow me to farm more content.

Another thing on my list is to port a (real) programming interpreter - so far wren and berry have been decent cadidates, but we’ll see. I want to keep the shell more of a command prompt, rather than someting programmable with ifs and fors. I generall dislike bash/unix shell - it allows for some truly unhinged programming, which shouldn’t be the role of such tool. Leave programming to programming languages and basic commands to shells.

To conclude: I’m locked in now and not in a mood for writing this poetry, yet I still feel like I have to. I have to, so I don’t lose form and so that maybe the two people in the entire world have something cool to read.

See you in the next post!
