Clarification of "AppDirAssistant is no longer the recommended way to generate AppImages"

[develar]

Hi, I am going to support AppImage target in the electron-builder and have couple of questions.

In the build.sh I see

AppDirAssistant is no longer the recommended way to generate AppImages.

1. What I should use instead? Where are binaries?

2. Where can I grab AppRun? I see https://github.com/resin-io/etcher/tree/master/scripts/build/AppImages but where is official download? I don't see in the https://github.com/probonopd/AppImageKit/releases or bintray.

   In the wiki no info about it, only that it should be.

   (I understand that maybe I should build AppImageKit to get it, but you know, it is very inconvenient and insecure (e.g. possible question from user why electron-builder doesn't use official builds?)).

3. Is it possible to build AppImage (convert dir to AppImage) on MacOS? I assume format is simple and should be easy to port.

1. Got it. AppDirAssistant is deprecated, but AppImageAssistant not.

2 . Found :) But why etcher use x64/x86 variants instead of just x86? @jviotti could you please comment? It is just "because better" or are there strong reasons? It seems #139 is the answer why.

Where can I grab AppRun?

Currently https://github.com/probonopd/AppImageKit/releases/download/5/AppRun

Hi @develar ,

Do you mean why we use x86_64 instead of just x64? If so, its only a naming convention that we kept adhering to for historical reasons. Happy to rename to x64 if that clarifies things for our users.

Please use the architecture names used by arch(1).

@jviotti Thanks for answer, I mean why do you have to use special build (x64) instead of released official build, but after that I found issue #139 If I understand correctly, you need to build AppImage for both arch but AppImageAssistant doesn't support it.

@develar Right, I've pre-compiled both AppRun and AppImageAssistant, and I run the build scripts on VMs on each release. #130 seems to be the answer.
