Distributable package size

[omar.aboumrad]

Greetings,

Hope everyone's doing great, I'm new to Lua, LOVE and thus this forum. I have an inquiry concerning the distributable package size.

love-0.9.1-macosx-x64.zip is 3.9MB

and yet when I package the app (as per the instructions here) as a zip file, I end up with a ~10mb MyGame.zip

Code: Select all

$ zip MyGame.love main.lua
$ cp -r love.app MyGame.app
$ cp MyGame.love MyGame.app/Contents/Resources
$ zip MyGame.zip MyGame.app
-rw-r--r--   1 [me]  staff    10M Oct 23 11:19 MyGame.zip

I would've assumed the end product to be relatively close if not less than the original love app zipped. Is it possible to achieve a 4mb zipped game? (assuming barebone)

P.S.: I'm on mavericks and my game is a couple dozen lines of code with no additional resources.

Thank you for your time!

Maybe it has to do with zip/compression settings ?
You could try with the app Keka with max compression!

[zorg]

the zip program has flags that can set the compression to be stronger; the default setting (6) was probably not what the devs used to package the distributables.

you could try

Code: Select all

$ zip -9 MyGame.zip MyGame.app

that should give you max compression.

Thank you for your replies. I should've mentioned that I already tried the -9 switch, but here it is again:

Code: Select all

➜  game)  zip -9r pixy.zip pixy.app
➜  game)  ls -lah *.zip
-rw-r--r--  1 xterm  staff    10M Oct 23 15:25 pixy.zip

I've also tried Keka with max (slow) compression and it yielded almost the same result.

It might not be preserving the symlinks inside the .app when you zip it. If it resolves them instead, then you'd get 3 copies of each library inside the .app.

I believe there's a flag you can use with the zip command to make it do the right thing, but I forget what it is.

It's -y.

Magnificent!

I wouldn't have thought of it for the life of me! Thank you slime and bartbes!

FYI, this initial problem was, copying the love.app folder locally to avoid tampering with the base one, which forced the libraries as slime mentioned to be copied and the symlinks ignored. Hence, the primary issue to deal with is how to preserve symlinks during copies.

That's achieved using:

Code: Select all

$ cp --preserve=links love.app /path/to/destination

Or simply just preserve everything recursively:

Code: Select all

$ cp -av love.app /path/to/destination

That however is not enough, it's imperative to use the "-y" switch as bartbes has mentioned to make zip maintain the symlinks instead of handling the files as is.

Code: Select all

$ zip -ry MyGame.zip MyGame.love

P.S.: Does this issue not merit being added as a footnote to distributing the app on Mac OS X?

Cheers!

Wow, I did not know that. That may be a useful footnote, yes. :-)
