Dos Shell

[desertfish]

This is a "unix" inspired Dos Shell with a bunch of builtin commands to make day to day file operations (much) more convenient than via a regular Basic prompt.

Tip: save this as AUTOBOOT.X16 to your sdcard and it will load every time you start the machine.

A short description of the commands and the source code (Prog8) is available on github

There is some preliminary support for running separate external shell commands (or 'plugins' if you like), details on how to write those are on github as well. Finally, the pwd command can print a wrong result on official kernal roms, because it tries to use a new feature to obtain the current directory that has not yet been added into the offical rom at the time this post was created.

Note: it looks like the shell's file functions act a bit unreliably in the web-emulator. Sometimes you get errors, sometimes not. On the real downloadable emulators, it works fine.

Can this be compiled as a ROM? If so, what are the steps to do so? I'd like to insert this into my custom X16ROM like I've already done with x16edit. Thanks

i guess you could rework the program, to be usable in the rom, but it'll require serious modification of the source code and potentially break compatibility with existing external commands for the shell. but anyway, why'd you want to embed it into ROM?

As Adiee5 already pointed out it would require substantial rework of the assembly code of the program.

Prog8 is not designed to create code that is ROMable, unfortunately.

Thanks.
It was to be for my own curiosity, really. But taking a day to ponder, it probably wasn't a good idea to begin with.

updated the program with a bug fix for launching programs that are not named in "normal" case.

[desertfish]

Updated with "time" and "date" commands, message of the day file support, and tab filename completion.

So, my board came in yesterday and I'd like to add shell.prg to my autoboot.x16, but there's a problem.

My monitor required some geometry adjustments to get the image to fit on screen, which I saved to nvram. However, shell resets the screen geometry back to default on startup which hides the prompt.

I find the shell very nice to use. Is there a simple workaround for this issue?

I'm working on an updated version with improved configuration options. Stay tuned.

We're testing a new version of the shell with all configuration being done in a separate config script that you can tailor to your needs
