UNIX for Dummies Questions & Answers

I am looking for a simple BASIC Interpreter written in a shell scripting language.
For me something like this would be a great learning tool...

After much goggle eyed Googling I came upon this:-

https://gist.github.com/cander/2785819

It is small and I haven't tried it yet as I am at work ATM.

However does anyone out there know of a cool BASIC Interpreter written in "bash"?

TIA...

Asking for one written in shell script limits your options a lot.

I can't help but wonder why, though.

Given that bash is supposed to accept Bourne shell syntax, why not just use bash to execute the Bourne shell BASIC interpreter provided? Sure, it will be SLOW and maybe you can make use of some extended bash features to speed it up a little, but I agree with Corona688: Why would we want to waste our time reinventing this wheel?

The reason is I learn "languages" best when it is adapted to something I am interested in.

"Banging the metal" is my forte and the AudioScope is an example of my abilities, albeit with a somewhat primitive coding style presently.

Any language that can create a BASIC interpreter no matter how small usually has some tricks up its sleeve(s), and this is the main reason.

I respect those coders who can create OSes, (I am a member of MikeOS), and have contributed HW related stuff:-

MikeOS - simple x86 assembly language operating system

One being a modified USB KB to give a slow serial I/O for a BIOS only OS.

Also those who can create compilers and interpreters get my vote too.

When studying the code for these things I learn a great deal.

UNIX style shell scripting is my new "platform" FTTB and with your input I am learning complex stuff very quickly. I still search continuously via Google for strange requirements for the Scope and enjoy every minute of it.

You have inadvertently become my mentor and all I can say is thanks...

Now you know... ;o)

"Because I find it interesting" is a good enough reason really

I admit, gwbasic and qbasic were the handiest, quickest languages for graphics I ever used... Just screen 12, line x1,y1 - x2,y2 and you've got a line, no need for 4 paragraphs of libraries and window initialization code. I know of no modern equivalent that's so charmingly straightforward. I still fire it up in dosbox sometimes for quick and dirty experiments.

Of course, BASIC also has egregious limits too, but it is what it is.

Hi.

Google search of linux basic interpreter led me to things like this:
--http://www.thefreecountry.com/compilers/basic.shtml

That might get you started -- if the parser is written as a shell script, then part of your work is done. There were 4 million hits on the Google search.

Best wishes ... cheers, drl

Hi drl...

I have already seen BaCon BASIC from Googling, thanks nevertheless...

Due to an infraction on my part I am in -ve equity and this might not be posted.

So if it is I am now rigged for silent running for a while...

See you guys and hopefully this will be uploaded...

BFN...
