Arduino Legacy Portable 1.8.19 Dev Test 4

What about version 2?

I'd like to see the currently latest Arduino IDE 2.1.1 in portableapps format.

I'd like to use the Java in CommonFiles folder instead.
Symbolic link with mklink /d is effective and non-official but only works on NTFS.
Do you have better ways?

According to https://forum.arduino.cc/t/forcing-java-64-bit-with-arduino/1076759/5
It seems that the Java path is hard-coded.

The PAL:DataDir folder seems to have no purpose.
The real data is in the portable folder instead.

There won't be any update to the main app, so it's trivial.
But this seems weird to me.

On Windows 7, if java was replaced, for example either with:

• Adoptium Temurin JRE 8.0.412+8 x86
• Liberica Standard JRE 21.0.3+10 x86

Then it won't launch with ArduinoPortable.exe
But it will launch successfully if directly launched with arduino.exe within the App\1.8.19 directory.

Some tools will fail to open with ArduinoPortable.exe, but it will successfully open if directly launched with arduino.exe

For example: Guino https://www.instructables.com/Guino-Dashboard-for-your-Arduino/

java.io.IOException: Cannot run program "C:\ArduinoPortable\tools\Guino\tool\guino\GUINO.exe" (in directory "C:\ArduinoPortable\tools\Guino\tool\guino"): CreateProcess error=2, The system cannot find the file specified

It should be C:\ArduinoPortable\App\1.8.19\tools\Guino\tool\guino\GUINO.exe
I think the IDE couldn't detect that the directory has changed because indirectly launched (not by arduino.exe).
What's the solution?

Beside the portable folder that I've mentioned before.
arduino.l4j.ini and arduino_debug.l4j.ini should also be in the Data folder.

Somtimes we need to increase the -Xmx<maximum heap size> to avoid the error of Exception in thread "AWT-EventQueue-1" java.lang.OutOfMemoryError: Java heap space.

With the new update, I think you forgot to rename the file of ArduinoPortable.ini to Arduino1Portable.ini
Otherwise it could not be launched.

Based on the format of another PortableApps of legacy apps, such as Mozilla Firefox, Portable Edition Legacy 115. I think the current Name variable is awkward.

it's better to rename it as Arduino IDE Portable (Legacy 1.8.19).
Since the PortableApps.com Platform will strips out the Portable word, it will shows up in the app list nicely as Arduino IDE (Legacy 1.8.19)

WaitForEXEN

Value: another_optional_app.exe
Optional.

If the program that you run is a launcher program which launches another executable, and you need to wait for that as well as (or instead of) the original program, specify its file name here, as WaitForEXE1=whatever.exe. If you need more than one, use WaitForEXE2, WaitForEXE3, etc.

Arduino 1.8.19 is a Java based GUI app.
Based on: https://github.com/arduino/Arduino/blob/master/build/windows/launcher/co...
The main arduino.exe launches another executable of javaw.exe

Without WaitForEXEN, the ArduinoLegacyPortable.exe will not wait for the javaw.exe to exit, and the [DirectoriesMove] section will execute prematurely. This will cause data loss for the app.

Please consider to fix the ArduinoLegacyPortable.ini by adding the [Launch] section's entry with the key and value of WaitForEXE1=javaw.exe

[Launch]
ProgramExecutable=1.8.19\arduino.exe
WorkingDirectory=%PAL:AppDir%\1.8.19
DirectoryMoveOK=yes
SupportsUNC=yes
WaitForEXE1=javaw.exe

[DirectoriesMove]
portable=%PAL:AppDir%\1.8.19\portable

DefaultData is usually used as a container for the default files to be placed within the Data directory. Generally, the launcher, when run, will check if there is a set of files within Data and, if not, will copy them from DefaultData.

Furthermore, the folder structure needs to be proper.
The portable folder should be in the DefaultData folder instead of in the App folder.

And also the default portable folder's content should be empty.

Tested and works.

Java created a directory in "C:\ProgramData\Oracle\Java". You need to handle this too.

[DirectoriesMove]
-=%AllUsersAppData%\Oracle\Java

[DirectoriesCleanupIfEmpty]
1=%AllUsersAppData%\Oracle
