dojs's Issues

red/blue colors inverted

the red and blue colors are inverted when running DOjS in 32 Bit mode ("-b 32") with a "mpeg" video.

Setting a font in p5js compatibility mode crashes DOjS

Due to a defective finalizer for the Font-class the system will crash when GC-ing an internal font object.
Will be fixed in the next release...

Running DOjS with modified EXE name does not work

In theory it should be possible to rename DOJS.EXE and JSBOOT.ZIP to, lets say, FOO.EXE and FOO.ZIP.
Running FOO.EXE without additional parameters should run the script MAIN.JS in the FOO.ZIP.
This does not work because DOjS still searches for the bootfiles in JSBOOT.ZIP instead of FOO.ZIP.

Disabling ALPHA channel crashed DOjS

Using the -a flag in dojs.ini crashes DOjS

Try to include GrxFontConv as DOS EXE into distribution

this would ease font creation for users...

Correct path structure for DOjS projects?

Hi
Hi
Just testing out DOjS. This looks great :)

DOjS V1.10.0
Windows 95 OSR2.x, FreeDOS 1.3

I am testing DOjS examples and also attempting to test jiyuai V0.0.2
Q. What are the script files path relative to? (The script file location, or DOjS.EXE location)

DOjS script examples are a sub-directory of \DOjS aka \DOjS\examples\*.*
Examples run without issue.

---

I placed jiyuai as a subdirectory \DOjS\jiyuai\*.js
.\DOjS\jiyuai\MAIN.JS
.\DOjS\jiyuai\ui\ui.js
If I run the script from the script directory:
Batch

@ECHO OFF
SET PATH=%path%;C:\JSDOS\DOjS;C:\JSDOS\DOjS\jiyuai
REM CD C:\JSDOS\DOjS
CD C:\JSDOS\DOjS\jiyuai
CALL C:\JSDOS\DOjS\DOjS.EXE -r C:\JSDOS\DOjS\jiyuai\main.js

I get errors from: Include('./ui/uiapp.js')
ReferenceError: 'Include" is not defined
DOjS ERROR

---

If i run the .\DOjS\jiyuai\main.js script from the DOjS editor.
SET PATH=%path%;C:\JSDOS\DOjS;C:\JSDOS\DOjS\jiyuai
I get:

Erro: Could not load "./ui/uiapp.js"
    at Require (JSBOOT.ZIP=JSBOO/func.js:214)
    at Include (JSBOOT.ZIP=JSBOO/func.js:224)
    at C:\JSDOS\DOjS\jiyuai\main.js:4

main.js

var inputStr = '';
Include('./ui/uiapp.js');
Include('./demos/dlgdemo.js');
Include('./demos/scrdemo.js');
Include('./demos/ascdemo.js');
Include('./demos/wdgdemo.js');

...

I have tried changing the paths to reflect the location of the script in relation to DOjS directory, ie. Include('./jiyuai/ui/uiapp.js'); Include('jiyuai/ui/uiapp.js');
I have some partial success using DOS file names: Include('.\ui\uiapp.js');

---

If I place jiyuai files in the root directory next to DOjS everything runs as expected without error.

\DOjS\DOjS.EXE
\DOjS\main.js (jiyuai)
\DOjS\ui\\*.js
\DOjS\ui\*.[DIR]

Must libraries be a sub-directory of DOjS.EXE?
and
Can I place the main script.js in a sub-directory?
Or are scripts meant to be in the root along side of DOjS.exe?

Sorry for the long explanation.
This may be related to jiyuai, but I also need to work out the correct location of scripts an paths for my self as well, otherwise I will end up with a root directory mess and name conflicts everywhere lol

Best regards
Axle

add tar support

Include() and Require() hide parse errors

When loading JS modules with syntax errors Include() and Require() treat parse errors the same as "file not found".
This should be optimized for better error reporting

Compilation

Thank you for developing for DOS!

Could you please publish the binary as well? I normally work on DOS and don't even have a Windows 10 and especially any Linux PC. I don't have any hope to ever have your program until someone compiles it for me since cross-compiling is not an option and it won't compile on DOS with native DJGPP, at least with these settings and my understanding of C is not deep enough for any trickery.

Thank you :)

check compatibility with HX DOS-Extender

https://www.japheth.de/HX.html

Compilation Problems take 2

its not a matter of using it... its a matter of not spreading garbage in the world... i would not use a project that is as dumb as requiring win10 to compile something for DOS... so without that fixed... i can't promote... to the contrary... all my reviews of the project would be terrible... and so on...

so dont make garbage for DOS... if you are not ready to honor people that code for DOS.... you are just destroying the meaning of all of it... so PLEASE STOP MAKING DOS STUFF if you will act like retarded against DOS

QuickJS

Are you familiar with QuickJS?

https://bellard.org/quickjs/
https://bellard.org/quickjs/bench.html

Looks like is much faster and much more standards compliant than mujs/duktape.
No idea how well it would work in DJGPP, though. Will have a closer look some time..

mikmod creates WAV file when no soundcard is detected

Will create a v0.9.1 in the next days to address this...

Add XML support

e.g. by using https://github.com/michaelrsweet/mxml

add support for libdmk

Misleading error message when JSBOOT.ZIP is write-protected

I tested "SpaceButton" recently, and due to the way I transferred the game to my retro PC (using a CD-R), the game files were read-only, which resulted in an error message "Script name missing". Once the write-protection has been removed on the game data files, the game started working normally.

Steps to reproduce:

1. Download https://superilu.itch.io/spacebutton
2. Copy the files to a folder on a Windows 98 SE machine (not sure if relevant)
3. Select all files, open file properties, check the "Read-only" attribute
4. Try to start the game using run.bat (from within Windows, again not sure if relevant)

Expected result:

• Game gives an error message that the files are read-only, or game works with read-only files

Actual result:

• Game exits with the message "Script name missing."

Build Problems

can you please fix this retarded way of build it? to just requires a .sh or a makefile or a .bat

not anything retarded like windows 10 or linux subsystem/emulation/etc?

Execute external program

Is it possible to execute external program and use the returned value? Something like var val = exec('time').

OpenGL support

Might be fun to have OpenGL available, possibly with WebGL-like bindings.

OSMesa can be built with DJGPP, probably at least the "softpipe" driver should work for DOS (not sure if llvmpipe works): https://docs.mesa3d.org/osmesa.html

There's some example code and a static library available here for faster integration:
https://bisqwit.iki.fi/jutut/kuvat/programming_examples/walk.cc

Mikmod init may crash/freeze DOjS

At least on one of my boxes the Mikmod init has a problem with the sound card.

I'll add the option to disable sound again.

Add PDF rendering

Try using https://github.com/AndreRenaud/PDFGen for PDF rendering

File/Socket-Operations should not use IntArray but ByteArray

IntArray stores each byte into an uint32_t, this is 4 times as much space as needed.
There should be a ByteArray type, based on IntArray...

glide3x.DXE: module loading failed

Using cURL and HTTPS crashes

File object should provide the possibility to seek() and read only parts of the file into memory

This should be implemented together with #30 for maximum benefit

add support for ADF files

https://github.com/lclevy/ADFlib

Add API for zlib/bzlib/etc

Based on File() and ByteArray from #30 iimplement an API for zlib/bzlilb./etc data (de)compression.
Make everything not zlib a loadable module.

Add INI file for command line options

Right now some options can only be changes using command line parameters (e.g. screen resolution).
It would be nice to be able to put these command line parameters into an extra file for distributing SW created with DOjS.
This way the user can start the EXE and no BAT needs to be included if command line options are used.

Video playback question

Hi, thank you for quick support of nanojpeg library.

I want to make the best dos launcher with downloading metadata from internet.

Can you give me a hint of some video player component that could be used as a part of Dojs UI? Any format. It can be Autodesk FLI or Mpeg or Mjpeg or Smack video component used in games.

"memory fouled" error after runtime exception/error

DOjS will exit with the message "memory fouled" and DJGPP/CWSDPMI register dump when a script error occurs.
set_last_error() in DOjS.c has a typo in strlen() invocation.

Will be fixed in a maintenance release soon.

3DF files for 3dfx GLIDE can't be loaded from ZIP files

The GLIDE3 code only supports loading via stdio, not from memory.

Black screen when running on FreeDOS 1.3 on WMware player

I'm trying to run the example 'exampl.js', but when i run it the screen goes black and the machine stops responding and the only solution is to restart.

Add command for use on dos browser

Hi,

can you add in program the commands used on web (web javascript capability) for integrate your proect into DOS browser (e.g. Links browser)?

DOjS Package problem

I was going to update the repository from version 1.6.1 to the latest version 1.7.0. However, there is a problem. It appears you inadvertently included a couple non-redistributable files in the release package. You will want to correct that as soon as possible.

/examples/blendfx.js Missing "examples/rose.png"

Hi
Just testing out DOjS. This looks great :)

DOjS V1.10.0
Windows 95 OSR2.x, FreeDOS 1.3

The example blendfx.js is missing the rose.png from the examples directory.
Line: 88 rose = new Bitmap("examples/rose.png");

I checked previous versions and has never been included. I tried an arbitrary 400x400px 8-bit 256 color with alpha and receive "Exit code 1" so I haven't gone any further down the rabbit hole :)
I have not tested all examples yet...

I am attempting to work out some other quirks (related) while becoming familiar with DOjS (seperate post).

Kind regards
Axle

Any plans to include TCP/IP capability?

It would be very nice to be able to interface with a packet driver, open websockets to an IP address, send and receive bytes, etc... do you have plans to include this capability? I know things like WattTCP and picoTCP do exist that could be used.

Also something that could be done, though I'm not sure how difficult this is, is to also include the capability to use Windows 9x websockets if the program is running on Windows. I do know that it is possible to do this from a DOS program running on Windows.

LoadLibrary does not work on 2nd run when using integrated editor

Steps to reproduce:

1. dojs newfile.js
2. Add LoadLibrary("curl"); to the top
3. in Setup() declare var https = new Curl();
4. Allow program to run, then exit
5. Run again
6. ReferenceError: 'Curl' is not defined

The issue goes away temporarily if you save the project, close the editor, and reopen, but this becomes understandably tedious

Shifted screen and wrong colors

Ok so I have a function render() that

1. calls System("wget ...") to get a list of pixels (x,y, and color) and save them in a file
2. loads the file with new File()
3. clears the screen with ClearScreen()
4. uses Plot() to fill the whole screen with pixels from the file

It works fine with the first two calls, but with third call the screen is shifted to the bottom-right by about 30-40px and the colors are wrong, I can't even move mouse above that shifted position and when I move the mouse to the right it appears on the left side (just as the image). When I repeat the render() call, it shifts by another 30-40px as you can see on the attached screen (sorry about the quality but its a photo of the Libretto screen :D).

Disabling the cursor

Firstly I would just like to congratulate @SuperIlu on the work that has been done to date. This project is really awesome!

Is there a way to disable the cursor during runtime? I can see how it might be useful in many cases, but I would like to hide it for some situations.

Could this make standalone exe which dont need any external files?

Hello,
i wonder if Could this make standalone exe which dont need any external files?

If yes, which versions of MS-DOS are supported and what is size and memory footprint of minimal hello world?

add support for D64 images

https://github.com/GroundhogGrafix/D64-C-Library

VSCode plugin is missing in the repository

Can't use let or const

I'm going to guess it's because I'm doing something wrong, but writing something like "const thing = 1;" just gives me an unexpected token error. Is there something I'm missing?

nanojpg

have you been thinking about including jpeg support?
we have png, but those can get rather large..
this looks nice:

(by the way, have you tried compiling sqlite3.exe shell using your compiler flags? there's no recent dos compile of that anywhere;
i tried loading sqlite.dxe with jsh but it didn't work)

Look into "VBE 3.0 not available" messages when font/bitmap-loading fails

Allegro seems to not set the error message correctly when loading fails and that leads to missleading stacktraces

http_get() is super slow

It takes ~40 seconds to load 10kb of data while wget (which also uses WATTCP) reaches download speed of ~100kb/s.

I've tested this in FreeDOS 1.2.
