Portable App Development

I've come across a case where Language:CheckIFExists requires wildcard support - Caesium Portable. Incidentally, there is also a need with this app for launcher.ini to support unicode characters, as these language file names are saved in unicode.

Hello,

I'm not sure what the most appropriate place is for me to post this problem so I would very much appreciate it if you could please share that with me?

I'm trying to change the permissions for Portable Google Chrone from
Read Only in XP Pro.

I've accessed Administrator as well as regular user to change it but
it's not retaining the changes.

There's a green box inside a larger box next to Read Only. I can
remove that green box and click Apply where it prompts me to apply to
all folders and sub-folders with I do next to that option. I click
Apply and then OK.

Since PAL looks for Data\settings to determine whether or not to copy over the DefaultData, it can clobber existing data if that folder does not exist (because the old launcher did not use it).

In addition, if the user installs a PAL portable app and then sticks their own profile in without launching it, PAL will corrupt and/or wipe it with DefaultData.

It's a toolbox with various hacking programs that will help you very much!

What are now the tools to create such an application that are posted here ? When I search I often find tools several years old, and it's easy to miss a note that tool is outdated or that development of given tool has moved to another website or thread.

So what I must download and what I must read ?

Example: In Google Chrome Portable with Portable Passwords enabled, if the user enters the wrong master password or hits cancel, the launcher should abort.

Right now this is only possible with the Abort keyword in the Init function. Anywhere else and you have missed cleanup work! The Init function of course runs before the splash screen, and before the checks for secondary launch and crash detection, making it less than ideal for some of the stuff you might want to do there (in my case, show a password prompt on the primary launch).

Downloaded the app via the link provided above. I get the Portable App splash screen in B&W and then nothing. I checked my processes, but don't see any new items shown.

I had my brother also download it and try it with the same result.

We are both running Win XP Pro SP3.

Thanks for building the app!

In said macro, we see this:

Push "${_VARIABLE_NAME}"
Push "${_PATH}"

This results in Push believing it has multiple parameters due to the " being interpreted as an end string. It needs to be escaped somehow or something.

My band-aid fix was to do this to my local copy:

Push `${_VARIABLE_NAME}`
Push `${_PATH}`

Obviously the same problem, just less likely to run into it due to the uncommon use of the backtick character. Any other macros in PAL may suffer from the same problem.

In the documantation regarding the section [RegistryKeys] I found the following statement:

If you do not wish to save the data of the registry key to a file but only want to keep it safe and throw away any changes, set the “file name” to -, so you end up with -=registry key location.

I've been thinking about the meaning of this statement.

If you check the bottom of the PAL NSI, as you can see after the MessageBox for LauncherCrashCleanup, it goes down to PostExec and Post to run cleanup.

But the manual claims PostExec happens after the program is launched, which won't happen in this particular case. I am guessing the actual PAL behavior is as designed, and the manual just needs to clarify that. It might also be useful to provide a "emergency clean up" flag variable so custom code can check it.
