simple text editor

mpark

Here's a little full-screen text editor. It's like Notepad (in Windows) with word-wrap off, so typing long lines causes everything to scroll sideways.

It understands the following commands:

• ENTER(CR) Carriage return
• BKSP Delete to the left
• DEL Delete to the right
• ←, →, ↑, ↓ Cursor movement
• HOME Start of line
• CTRL-HOME Start of file
• END End of line
• CTRL-END End of file
• CTRL-O Open a file (on SD card)
• CTRL-S Save to a file (on SD card)
• CTRL-ALT-DEL Reboot

The code is a mess and no doubt full of bugs. Use at your own risk.
Requires HYDRA, NTSC TV, PS/2 keyboard, SDMAX SD card interface (conversion to non-HYDRA platforms should be straightforward).

Yeah! How long did I wait for this program... A microcontroller with video output and keyboard plug on a typical proto board should have a text editor. Thank you very much for that!

Wow! This is really fantastic!

Having tried to create something like this myself I can really appreciate what you have done!
Is there enough memory left to incorporate Doug's 40x23 text driver? AiGeneric might be
a little large, but perhaps his original driver?

How large a file can you edit with this?

Currently the text buffer is 20000 bytes but you can easily change that. There's still 600+ longs free.

I don't know anything about the other drivers you mentioned. Anyone who wants to hack the code has my blessing, but if you do, please post what you come up with.

WOW - This is great news. Should be useable on a quite a few projects so I have added it to my thread index. Might be usable on heater's ZiCog and my TriBladeProp. Also with PropDOS.
I have plenty of memory available (SRAM) on the TriBladeProp board.

Certainly lots of apps starting to appear. Now who is going to do a spreadsheet??? (supercalc anyone???)

Very nice editor!

Attached is a version which incorporates AiGeneric 2.1 with the ATARI font.
You'll now get 40x23 text. I'm pretty sure you should have the same amount of
editor space.

Way to go, OBC!

Now can you get homespun to run on either the prop (native) or else z80/8080 (for emulation on prop) easily???

We are almost there for a self-contained prop sbc
