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 texts 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

Tested with emulator version r38. Run with the following command:

  • x16emu -sdcard sdcard.img -prg X16EDIT-x.x.x.PRG -run

where x.x.x is the program version.

You can also run the program with the "Try it now" button. There is, however, no attached disk in the online emulator, and consequently you cannot save or open files. Also, some of the Ctrl+key sequences are not working in the online emulator. To fully test the program you still need to download and run it locally.

Please read the attached file romnotes.pdf if you want to try the ROM version.

What's New in Version 0.3.4   See changelog

Released

This release is mostly bug fixes and code cleanups.

A new feature to type in and execute CBM DOS commands from within the program has been added. This feature may for instance be used to delete or rename files. The feature is not limited to those commands, and any valid command may be executed.

The interrupt routine was updated to fire on vblank, making scrolling large pieces of text a bit smoother.

In the GUI the keyboard behavior when displaying a status message has been changed. Before any key would hide the message, but the key press was discarded. After this release the key is sent to the default handler normally inserting it into the buffer.

The ROM version has been updated to include a program and version signature. The signature is stored at address $fff0, and has the following format: "x16edit<appversion.major><appversion.minor><appversion.patch>". The signature may be used to verify if X16 Edit is present in a particular ROM bank.

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.

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.
