Full Screen Text Editor *fixed* (and moving toward expansion)

Oldbitcollector (Jeff)

This is version 1.2 of a text editor for the Propeller, intended as an add-on
tool for PropDos users. Launching the Propedit will allow you to create/load/save
text files. This version is limited to a single page of text, but that will be increased
in later revisions. Think of this as NOTEPAD for PropDOS.

This version has squashed the major bugs which prevented it from being useful.
I'm working on a few more cursor rule adjustments for the next release, but it
is now a *working* editor.

Give it a spin and let me know.

Edit Added:
A mutli-page version of this editor is also attached (Version 1.3b)
It is in Alpha, so I'm still bug chasing.. but it supports up to five pages of text.
Version 1.3b has most of the load/save bugs worked out.

Snow somewhere around 8" now..

A long overdue PropDOS update is also in the works....

*removal of PropCOMM (moved to separate file)
*addition of "DOS-like" execution of .bin files. (no more typing 'spin filename.bin')

Oldbit,

Keyboard pin in I/O settings for Hydra board needs to be 13 instead of 12.

Thanks. I think I have it right now.

Did some edits to improved switching between the editor and menu screen.
[noparse][[/noparse]ESC] now toggles between them. Loading a file now loads and takes you to
the editor. Also I've added a DIRECTORY command.

Interface feels more natural to use now..

Hi OBC,

Took your Text Editor for a quick spin today. I had to change the Keyboard pin back to 12 for use on a Hybrid. If left as 13 all keyboard LEDs just flash and no key input is possible. A very nice text editor, that should suddenly find many uses.

I did think of a possible upgrade to the Aigeneric TV driver, the ability to load a font stored on SD card instead of this being hard coded. Obviously you need something to
start off with (reference to this file stored in eeprom) select a new font set, also save this reference to eeprom then reboot. I see complications to this scheme, which looked great on paper. Did also think about a fixed status bar showing the X and Y information for the current cursor position, amongst other things.

Another nice project from the OBC collection!!

With regards

Mike.

I could have sworn I released a copy of Propeller Editor that worked with .64c fonts loaded from SD?!?

Sigh.. Can't keep track of my own releases..

If I haven't posted it, I will dig it up and see if I remember why.

This is a version of PropEDIT (CGEdit) which will allow you to load 64c fonts from the SD.
While it works, it's considered unfinished as it doesn't support font color. *yet [noparse]:)[/noparse]

I've discovered a real flaw with this release and haven't yet wrapped my mind around how to solve it.
(Perhaps a few more brains involved will be able to do more...)

I'm posting this because "stevenmess2004" asked, and I thought it belonged in it's own thread.

Here goes..

This Full Screen Editor grabs all keystokes (other than cursor controls) and keeps track in screen[noparse]/noparse.
As a result, all keystrokes are displayed on screen immediately.

When the file is saved, (and here's where I *think* the bug is, the empty spots are fulled with spaces)
and the file is written to the SD.

Another mystery is why normal text files are unable to load properly, but I suspect issues along
the same vein.

I think this could become a very powerful editor for the Prop, but it's going to require more
programming experience than I currently have myself...

I would suggest a separate buffer for the text all the time. Then you would probably need to write an assembly driver (spin probably isn't fast enough) to copy the stuff from the text buffer to the display buffer.

When you wanted to save or load something you just need to use the text buffer and not the display buffer which should be a lot easier. Also, if you filled the text buffer with spaces it should same you some other hassles.

You could set the assembly driver to either continually update the display buffer or to just update when asked to (say whenever a key is pressed). Also, you could make the assembly driver so that it started at some arbitrary place in the buffer and then you would be able to have more than one screen.

----
Well I just had a better look at your code and it looks like you are already doing half of what I suggested so its probably not all that useful...

vampyre

a good text editor is surprisingly hard to write, but i think stevenmess is on the right track.

i wouldn't update the screen except when its edited though, and then only the line of the screen the cursor is on. doing it that way probably wouldn't require ASM

Bob Lawrence (VE1RLL)

Great idea! I tested it with the Hybrid board and only made one change.

keyboard = 12 '' I/O for keyboard connection ' (changed it from 13) keyboard = 13 '' I/O for keyboard connection

Unfortunately my HD card quit a few days ago & therefore, I could not test that part of the program.

DUH! Finally hit me what is causing the bug in this editor!

I was fiddling with notepad while working on another project..

A corrected release will be uploaded in a day to so..

This is very nice. I just tried it today. I made something similar using TV_TEXT but for the use of a control panel terminal
so it doesn't save anything. What our programs both lack is certain keys such as insert and delete which should be
easy if we can find the cursor locations and use BYTEMOVE.

BYTEMOVE is probably also the key to scrolling and having a larger text file, by simple transfers between the
screenbuffer and a textfile in RAM when you push the cursor past the vertical edges of the screen.

Oldbitcollector (Jeff)

I've implemented BYTEMOVE to expand the editor to 5 pages.
I doesn't scroll *YET* and has a couple issues I'm chasing down,
but is another step in the right direction..

(Attached to the top thread)

Ok guys, we have a primitive text editor for the Propeller, now we need
some sort of compiler and we can move toward ditching Proptool, and
developing apps on the Prop itself...

Here's a thread on a compiler-compiler that runs on the Propeller, reads a source file from an SD card into a 32K "page" of EEPROM, then processes that to produce a 32K source file in Spin which gets written to another SD card file. The Spin file has to be compiled on a PC, but this is a step in the right direction. It can compile itself (the true test of a compiler-compiler).

http://forums.parallax.com/showthread.php?p=692011

If anyone wants to play with it, I have a partially written Basic to LMM binary compiler using a lot of the same code. I ran out of space and plan to split it up into passes when I have some time to work on it this Fall.

Oldbitcollector (Jeff)

I forgot about Meta! We're closing in on this... [noparse]:)[/noparse]

Here's my long ignored working directory, comes with no guarantees, no documentation or explanation other than that Ouroboros.spin is an attempt to create an editor front end, never quite worked. I think there was a problem with the SD card I/O routines. ExOuroboros.spin is the beginning of a compiler. It can process declarations and allocate storage and some of the code generation for expressions and simple flow of control seemed to work (just started being tested).

Clemens

Thanks, Jeff for this application.

Just for the fun of it I added Phils cool phonemic voice synthesizer.

Here's the related discussion of his work:

Press F9 in main menu to have the text read to you.
Makes it a lot·easier to try out different ways to write words to get them to sound right without having to compile a lot, doesn't it?

This is why I LOVE this forum...

I go to bed after submitting a text editor and wake up with a speech toy!
Collaborative projects are just awesome! Looking forward to playing with this later.

A question, did you notice that blank spaces are 1's and carriage returns are not 3's not 13.

Edit:
Actually this might even be nicer to add to version 1.3a as I update @screen on every pass
and F9 could just be added to the editor. Neat Idea!

You're right, it's even more comfortable with version 1_3a.
F9 now·speaks the text in editing mode also.
Now I have to do some character remapping, I'm using a german keyboard and finding those special characters on it is a pain...

Um, not really, no,·I didn't look at the code very closely, just pasted some lines from the talking demo. It's really amazing, how easy this is with spin.
Cheers,

Clemens

Oldbitcollector (Jeff)

Neat upgrade! A fun way to play with the speech toys!

I've attached 1.3b to the top of the thread.. It's a bit more stable in LOAD/SAVE.
It's dropping a character at the very end of each page, but it's close enough to be
useful as a multi-page editor.

Edit: Bah! New bug found, not saving files as truly DOS compatible.
I'll have this straightened out in a day or two. Then you'll be able to edit Femto files
as well.


I was day-dreaming the other day... What if we created a webserver running Propellant
that could receive a .spin file and send back binary? Wouldn't remove the PC entirely,
but it could make things interesting for those with a PropNIC. (or equiv)

I'm wondering if this text editor would work with Kye's new super Fat32 sd card code?

This program could be just perfect for editing small autoexec and batch files that you can leave on the sd card and change settings without having to recompile spin programs. Useful for 'out in the field' applications.

It would work, but it needs a good re-write..

I dropped the project after mparks editor was released, but for the life of me I can't find the thread.
Also Casslan did an excellent editor as well.
