Release

File Tree 0.11 (DOS)

SP4CEBAR 2022-07-01 09:38 (Edited)

This is a tree file structure (folders in folders in folders), you can use it to efficiently use your RAM Navigate through a tree of files and folders like in windows CMD or MS-DOS

• Type "DIR" to list available directories, follow it by a number to view the next page (there's no scrolling)
• Type CD followed by a number to go to the directory at that number, for example "CD 0" opens the first directory
• Type "CD .." to go up one directory
• Type "CD" to go to the root directory (the base, in this case also the place where you start)
• Type "CD" followed by a file path, to go to that file path, for example CD C:\0\0\1 goes to a file with a size of 9 bytes
• Type "DEL" or "RMDIR" followed by a number to delete that file or directory (yes, they are interchangeable at the moment)
• Type "MKDIR" followed by a number to make a new directory, the number is the position: 0 is the first directory
• Type "MKFILE" followed by two numbers to make a new file, the first number is the position: 0 is the first directory, the second number is the file size
• When you've navigated to a file, type "CF" to change the size of that file
• Type "ALL" or "MAP" to list all files and directories, follow it by a number to view the next page (there's no scrolling)
• HEX shows the raw data in hexadecimals, follow it by a number to view the next page (there's no scrolling)
• ROM or DISK shows all ROM entries in the disk and their name and size, follow it by a number to check for a specific rom entry
• SAVE n saves the file tree to rom entry n
• LOAD n loads a file tree from rom entry n
• RESET resets to a bare file tree (only a root directory)
• INIT returns to the demo file tree
• END, EXIT, QUIT, STOP, or E stops the program and turns off the keyboard

The numbers show: the list count, the address in hex, the size in hex, the size in dec which serves as the name

this GUI system is based on this file tree

Also, the mobile NX app occasionally crashes when you exit the program with the keyboard on, it may also happen on the PC version, so keep an eye on that, more information here

Next I'll work on writing, deleting, and recursive path following,
These subprograms will be really useful, because they make and maintain the file, you can use it to use your RAM efficiently
I'll use them to store (and save) data for a new tool I'm working on: GUI Designer!

V0.1

• You can now delete files by typing "del 0" inside the directory you're in (This is a bit of a temporary syntax, I should link it up together with CD so that you can use the numerical values, but at least it works

SP4CEBAR 2022-07-01 14:19 (Edited)

V0.2

• To display a directory or file properties, you now need to type "DIR"
• You can now type DEL with a number to delete that file or directory, you can also use RMDIR (Yes they are interchangeable at the moment)
• You can also type CD with a file path, for example CD C:\0\0\1 goes to a file that has a size of 9 bytes

SP4CEBAR 2022-07-01 17:12 (Edited)

V0.3

• You can now use "MKDIR" followed by a number to make a new directory (folder) before the directory of that number, I was debugging this not realizing that it already worked: it kept showing directory is empty, because the newly made directory was opened, by the way, in this version it still says that, wait for the next version for more bug fixes
• If you navigate to a file, you can type "CF" to change the size of the file, this is not a DOS command, but it's something that's really useful inside programs, this program's main purpose is to test if the subprograms work

SP4CEBAR 2022-07-01 17:55

V0.4 bug fixes

• "MKDIR" returns to the right directory level
• "MKDIR" fixed
• "DEL" fixed

SP4CEBAR 2022-07-01 18:50

V0.5

• added "MKFILE" followed by two numbers separated by a space to create a file above the directory of the first number, with a size of the second number
• I realized that my user input decoder needs to be rewritten a bit because it can only detect the last decimal of a value

SP4CEBAR 2022-07-01 22:54 (Edited)

V0.6

• the user input decoder has been rewritten, it can now extract up to four values

If you find any bugs, let me know: tell me the file path and the command(s) and parameter(s)

SP4CEBAR 2022-07-05 20:47 (Edited)

V0.7

• type "ALL" to list all files and directories
• "MKDIR" can now create directories in empty directories, and it can add a directory as the last directory of a directory, the same goes for files with "MKFILE"

SP4CEBAR 2022-07-06 22:59 (Edited)

V0.8 a lot has been added - this version is the first release!

• ALL now shows the file structure
• HEX shows the raw data in hexadecimals
• ROM or DISK shows all ROM entries in the disk and their name and size, follow it by a number to check for a specific rom entry
• SAVE n saves the file tree to rom entry n
• LOAD n loads a file tree from rom entry n
• RESET resets to a bare file tree (only a root directory)
• INIT returns to the demo file tree
• END, EXIT, QUIT, STOP, or E stops the program and turns off the keyboard

Bugs fixed:

• DEL deletes it's trash (data at the end of the file)
• the file is reset correctly so that new directories and files can be made
• MKDIR and MKFILE now have the right address

SP4CEBAR 2022-07-06 23:21

The command "CF" still has one or more bugs though

SP4CEBAR 2022-07-07 14:05

V0.9

• fixed CF
• type a number after "HEX", "DIR", or "ALL" to go to the next "page" (there's no scrolling, this is a little workaround)

SP4CEBAR 2022-07-07 15:31 (Edited)

V0.10

• removed the "FIL" tag of a file to make it more similar to MS DOS
• cleaned up the code (by removing trace and commented-out code)

SP4CEBAR 2022-07-08 08:32 (Edited)

This program can be added as an NX tool to make, edit, and inspect preset folder structures (stored in ROM)
The subprograms of this program can be used to optimize RAM usage
It's more or less finished, what do you all think about it?

SP4CEBAR 2022-07-08 17:40 (Edited)

V0.11 - one bug fix

• "LOAD" now removes the remains of the previous file structure

what can you use to get text from the command for if i wanted to make the echo command

SP4CEBAR 2023-02-14 20:26 (Edited)

To add an echo command you could go to the long IF ... ELSE IF ... ELSE IF ... statement inside the subprogram named "DOS" to add code like this:

ELSE IF C$="ECHO" THEN
PRINT RIGHT$( N$, LEN(N$)-LEN(C$) )

To get rid of the extra space you could instead write

ELSE IF C$="ECHO" THEN
PRINT RIGHT$( N$, MAX(1, LEN(N$)-LEN(C$)-1 ) )

Where MAX(1, ... ) makes sure the value doesn't get below 1

N$ is the command typed by the user
C$ is the left-most word (before the first space) of that command
V0, V1, V2, AND V3 are numbers that follow after a command

for example if the command (N$) is "LOAD 2", C$ will be "LOAD", and V0 will be 2
These values are generated by the subprogram named "analyse"
