About This File

X16 Edit is a text editor for the Commander X16 platform.

Design goals:

  • Use plain text files
  • Store text buffer in banked RAM (512KB to 2 MB) 
  • Handle large text buffers efficiently
  • Simple modeless user interface inspired by GNU Nano
  • Implement basic editing functions well - refrain from making the program too feature-rich
  • Support both ISO and PETSCII modes

The current version of the program is made for X16 ROM version R41. Run with the following command:

  • x16emu -sdcard sdcard.img -prg X16EDIT-x.x.x.PRG -run, where x.x.x is the program version.

X16EDIT-HI.xxx.PRG is assembled to be loaded and run at memory address $6000.

To run ROM version you need to setup a custom ROM image. Please read the attached file romnotes.pdf to learn how to do that.

For instructions on how to use the editor, please read the attached manual.

This could be the beginning of a REAL built in BASIC  programming editor. Very nice work.

Response from the author:

Thanks!

A text editor is a programmer's tool. If the X16 is to become something more than a games console, you must be able to use it for native program development.

The editor could be used for any programming language. A version of Forth (Volksforth) is already published on the site, and it reads source code from text files. The same person is also working on a C compiler that runs natively on the X16, which sounds promising. An assembler that takes text files as input is at the top of my own wish list, much like the Commodore macro assembler I once purchased and used as a teen in the 80s. Editing Basic files is of coarse also very interesting.

Maybe someone out there is interested in writing any of these. If you have a solution, I'm very interested in integrating it with the editor, so that the programs play nicely together.

The new version published today is mostly focused on that kind of integration. The zero page and lower RAM usage has been minimized. The ROM version lets the user set what banks of the banked RAM is used by the editor. And the editor now takes a snapshot on startup of the zero page and lower RAM it uses, so that those memory locations can be restored on program exit.

This is a great editor indeed! And the source code is really nice to read as well.

My difficulty is that on the linux emulator, using r41 and version 0.5.4 of x16edit, neither the Ctrl+KEY nor ESC than key combinations work, only the FX keys and so I'm limited to what I can do with it.

Response from the author:

Thanks!

There's one know problem when running the program in the emulator. On startup the editor tries to read the  file X16EDITRC. If present that file contains custom keyboard shortcuts. But when running in the emulator the ROM doesn't report file not found when no SD card is attached, and it reads bogus data into the custom shortcut table held by the program. This is a known emulator issue already reported on Github.

Does the keyboard shortcuts work if you attach a SD card image, that is using the switch -sdcard scard.img when you start the emulator? Otherwise I have some debugging to do 🙂

Outstanding editor!  I have been using nano on the command line for years when developing, and this like solution is so intuitive and natural to use.  I will be working on the ROM integration next so

it can be coupled with the cc64 compiler being developed.  Thanks so much for porting to the x16.
