New update coming soon, may need a bit of help with it, but I'll see if I can figure it out first. Multi page notes list now works, but when trying to load up a note that is note #2 or higher, it keeps loading up note #2. strange. I'll figure it out or talk about it in a future post.

The main reason for this post:
i REALLY need a better way to display text after deleting, pasting, or most importantly, actually loading up the note. As I've said before, it currently does it character by character, since not all chars are 3 pixels in width, and my text editor is locked to a grid. I can't display it an entire line at a time, because the TI-OS has perfect kerning. chars like any of these ". ! [space] m w" etc etc need to have a special case be displayed, since they are not 3 pixels in width.

I really would appreciate some ideas here, if anyone can help me out It would speed up my program and make it a lot more user friendly by a BUNCH. Thanks in advance

You can now scroll through all your pages of notes, 99 being the page limit, which means 99*6=594 would be your note limit. The problem now is that if you click on any note that is note #2 or higher, it gets stuck at displaying note #2, or giving an error.

Here's the current code for the menu. Program TEXT is the text editor, which I will eventually just put into the same program as the menu. Also, the only relevant parts to my problem I believe should be the "If K=34 and (A=52 and dim(|LTIBN" etc and the "If P or B=87" part, but there may be some other parts that could be relevant due to all the variables changing.

Code:


Here's a test run, with this code:


Also, this will be mainly for my benefit, but I will post it here. These are all the variable usages. Some variables are temporary, meaning they are used in only a section of the code, and can be overwritten.
Menu
Code:

Text Editor
Code:

New title input. I tried mixing it in with the rest of the text editor for full functionality, but it seemed a bit too hard and not worth it. so, for the title, you can only input capital letters A-Z, you can backspace, and you can clear the title. now, actually getting it to replace the previously written title is a bit tricky. also, as you can see in the gif, the second note i wrote went into the first notes area, which is obviously not wanted. I am fairly positive that it is a problem with variable D, and could be caused by the "For(E" loop.

screenie:

i used str6 conveniently for the title, which is stored back into str9 when you finish inputting/editing it. there are several bugs, but I will make a separate post for that. for example, I tried moving my cursor around in the text editor, but nothing worked. can't even highlight, move, or do anything other than just inputting text. very strange. oh, and btw, I have not implemented the display of the note yet. It only displays the title. I will have to make it so that when you click on the note, it displays the note char by char, which is slow, but the only way I can think of. if you can improve my methods please do

also, I finally inserted the text editor code into the menu program, so it is now one big ginormous chunk of code...

Code:

((sorry for several posts in a row, but I wanted to make this a separate post completely))

Here I will post all the bugs and other things I need to complete and/or fix. There are several I have encountered along the way, but I have forgotten some. I will add them as I find new ones and mark them off when they are fixed. If you find any new ones, tell me

Things to Fix/Optimize

FIXED || FIX VARIABLE D - trying to display a note that is note #2 or higher does not work. it gets stuck at displaying 2 or errors out. along with that, storing notes/titles back into str9 when done editing is screwed up.

FIXED || can hardly do anything in text editor. no cursor movement, highlighting, etc etc

NOT FIXED || pasting doesn't paste what you think you copied. EX: copying " NOTE" in "4TH NOTE" and pasting it pastes " 4TH" instead.

NOT FIXED || cursor is able to move straight down even when the string does not reach that far. it should be moving backwards to the length(str7) but it doesn't

FIXED || if any functions are entered in y=, they might be drawn

MUCH FASTER || display of the note when going to edit one is slow, because it renders char by char. I wonder if there is a faster way to do it, while making sure all chars appear as 3 pixels in width.

...and more bugs I may have forgot. Will post when i discover them again

I like the new title input, its better than an Input command an make everything feel pretty seemless.

When you edit a note, and then going back to your homescreen, you must overwrite the previous content of that note. That is done in this part of the code:

Code:
, which is at the last lines of your big code.
But when you trace down that, you get weird results. Let's say Str 9 =
"XTtitleXNnote-contentXE", where the capital X is the xhat. if Str7 = "new-content", then you get:
sub(Str9,1,9) = XTtitleXN
Str7 = new-content.
sub(Str9,10,end) = note-contentXE
This is the result: XTtitleXNnew-contentnote-contentXE or something like that.
You could change it by replacing the last two XN's with XE.

Edit: remove the -1 at For( E ,1,6( C- 1)+ A/ 4- F -1

I hope soooo this helps!!!⁻¹

This is looking really good. When you finish, I am going to download it and use it on my TI-84+CSE because it is in pure basic and if I want I can just multiply a ton of stuff by 2.5 to get it all proportional to the graph screen size on the CSE.

Lots of bug fixing....

I am pretty sure there is a problem with D. It always seems to be 1, which is why when I write something in the 2nd note it replaces the first note in str9 instead. what may be relevant is the part "For(E,1,6(C-1)+A/4-F-1". you can do ctrl+f if you need to.

Code:

As I said, remove the -1. Hope that helps

that helped a tiny bit, but what happens now is that the second note gets replaced when you finish editing the 3rd note or higher, so... gonna need something else

For(E,1,(6C-6+A)/(4-F ? I know nothing about this, but I hope it'll help!

Nope, that doesn't work :/ that just goes back to the first problem, replacing the first note with the second note.

I think what I need is something like For(E,1,6(C-1)+A/4-F+<number>). Since setting <number>=0, it makes it work for the first 2 notes, but then replaces the second note with the third note if you do a third note. So, maybe <number> could start at 0 on the second note, and increment by 1 the higher the note number?

(read my previous post)

for <number>, I did the same exact thing but with -2 on it, that way it adds 0 if on note 2, 1 if on note 3, etc., so the entire thing would be
Code:

...but that just returns to the original problem - the first note getting replaced. anybody got any ideas how to fix it...?? what I'm wanting is that if on the first note, D is the value of first appearance of [xhat]T, if on second note, D is the value of the second appearance of [xhat]T, etc etc.

this isn't necessary, but here's the entire loop:
Code:

When editing, creating or deleting a note, it returns, but I don't know how. Have no time yet to look at it. Here is the code:
Code:
or
Code:

Michael2_3B: What does the variable D represent? I might be able to help if you post your current code and what all the variables do. I don't know what you mean when you say that D always seems to be 1. Maybe when you enter a note, you can store the number of that note to D or something. If I understand what it does correctly, which I think I do not.

Variable D represents the start of a note in str9. so, for example, if i have 2 notes, and here's an example of str9 (all notes combined in a string)

Code:

then if i decided to edit note 2, D would equal 31 (the second placement of [xhat]T)

but for some reason D get's stuck at the second placement of [xhat]T and doesn't go further (like, when you create note 3 or edit note 3)

Also, the code in this post should be updated enough. I just need to fix D, and i'll put the fixed code into my slightly newer code. but the new stuff i have added recently doesn't have anything to do with D.

Some parts of your code (I'm looking at the version from the 14th) confuse me. For example, you have this line:

Code:


There are two possible issues here:

* First, you don't need the parenthesis, because the and command has higher priority than the or command. (I see that PT_ had removed it in the fix.)

* Second, I don't think you need the -6(K=25) piecewise, because when K=34, which is the only situation it matters in, it will always return false. (The only way I could justify this would be if you'd otherwise go beyond the bounds of the list, but it looks like that's not the case since you've just gotten the value of K.)

Also, if I'm not mistaken, this block:

Code:


can be replaced with

Code:

If the first character in Str9 is always " ", you can further replace the sub(Str9,1,1) with " ".

I also noticed that in this block, as well as some others:

Code:
the parenthesis at the start does nothing, and this:

Code:
can be

Code:
or even:

Code:

(It's customary to use max( rather than sum( because the former is often faster.)

EDIT: You may also be able to use a single variable for both the [2nd] and [ALPHA] states rather than using R and S.

Would it be possible to give a complete listing of how each real variable, list, and string is used throughout the code to facilitate debugging and optimization?

EDIT: I was informed that the variable listing is here.

does that also take care of the fact that .01(var) can only go up to the 99? for example, V+.01X along with the sub() stuff would only go up to the 99th char for the X part. but with your min() thing, does that allow it to go to ~infinity?

I was originally just gonna change it to .000001X (or V) but now I'm curious if the min() solved it.

PT_: that didn't work. still need some way to fix D.

I'll see if I can look through my code line by line possibly and see what's wrong, but that will take a while. Help is appreciated! in the mean time, I think I will also start implementing some of the features I've been wanting to add, and the one feature I still need to add (which depends on D, however), which is the display of the note when you click on one to edit. other features like a search all notes function I may add here soon.

for anyone who doesn't know:

As I said on SAX, D is just 1 if you create a new note, which must be higher. What happens if you add that For(E - loop after creating a new note?
