packaging, signing, and Mac AppStore

[andrewarrow]

when I right click on a normal MacOS app I get "Show Package Contents" menu option and then all this inside the .app file ^

But with my wxGo file there is no Show Package Contents option. What's the process for distributing apps created with wxGo to the Mac App Store?

Hi, I have little knowledge on macOS really. The compiled file should be a normal executable file, instead of a package that contains other resources. Does macOS have any packaging tool?

[andrewarrow]

there must be a way to do this in xcode or the command line. But I think you would need an account with https://developer.apple.com/macos/distribution/ to sign the app and get it in app store. I'll research more because I really like your wxGo system! Thanks for making this.

I started a tool at: andrewarrow@0d7eafa

here is sample output so far:

github.com/dontpanic92/wxGo/macos $ ./macos mygreatapp
building skeleton for mygreatapp
creating dir
&{0xc82000e0c0}
~/dev/src/github.com/dontpanic92/wxGo/macos $ ls -l mygreatapp/
total 0
drwxr-xr-x  5 aa  staff  170 Sep 27 16:37 Contents
~/dev/src/github.com/dontpanic92/wxGo/macos $ ls -lR mygreatapp/
total 0
drwxr-xr-x  5 aa  staff  170 Sep 27 16:37 Contents

mygreatapp//Contents:
total 0
-rw-r--r--  1 aa  staff   0 Sep 27 16:37 Info.plist
drwxr-xr-x  2 aa  staff  68 Sep 27 16:37 MacOS
drwxr-xr-x  2 aa  staff  68 Sep 27 16:37 Resources

mygreatapp//Contents/MacOS:

mygreatapp//Contents/Resources:

the idea is to make all the values inside Info.plist it needs and place exe in MacOS folder. Then eventually add the signing.

So glad to hear that! However, currently wxGo is far from mature and there is still a lot of work to do.

Thanks for your work. Perhaps it is a general solution for all projects which are not compiled by Xcode.

[andrewarrow]

cool, yeah I'll keep going in my branch for the command line tool that auto generates a Info.plist. I have a template in there now with {name} fields that get replaced with the name of your app when you run it.

Hi @andrewarrow and @dontpanic92 !

on OSX here too and definitely desiring the .app as well 👍

I happened to have been curious as well about this topic some weeks ago, of getting form a binary to an .App.
Googling 'osx create application bundle from binary' I encountered quite some discussions and pre-existing solution on this more general problem as here or this or this.
Although I actually didn't have the time to test any, so I don't know if an existing tool already gets the job done..
If one exists I guess it may be done separately in a post-processing phase for OSX with proper instructions for the user in the readme ?
(this in case there might aspects, such as the icon, that might complicate things and be better tackled by a specialised tool while the library focuses on getting the binary out)

In any case: OSX here and available to help testing

Cheers 👍

@neonsoftware good to know. I haven't made much more progress with it but I am doing a lot of wxGo programming. I think wxGo is positioned nicely to be THE golang GUI for 2017. Let's replace all Java AWT and Swing stuff. Let's re-write Eclipse!

For anyone putting an application bundle together you might find these resources helpful:

"Anatomy of an OS X Application Bundle" from Apple's Bundle Programming Guide:
https://developer.apple.com/library/content/documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html#//apple_ref/doc/uid/10000123i-CH101-SW19

"Building a MacOSX application bundle" from the page "WxMac-specific topics" in the wxWidgets wiki
https://wiki.wxwidgets.org/WxMac-specific_topics#Building_a_MacOSX_application_bundle

In the interest of getting up and running quickly, for now I just created a Mac icon by converting my Windows icon:

sips -s format icns icon.ico --out icon.icns

nice! thanks @rakslice
