LÖVE 11.1 AppImage and relative paths

Post by grump » Mon Apr 16, 2018 2:14 pm

I don't want to upgrade my system to 11.1 yet, so I tried the AppImage distribution. I quickly learned that this doesn't work:

Code: Select all

$ love-11.1-linux-x86_64.AppImage game.love

Code: Select all

Error: [string "boot.lua"]:481: Cannot load game at path '/tmp/.mount_AjgSUk/usr/game.love'
Make sure a folder exists at the specified path.
It only works when specifying the absolute path to the love file/game directory. This seems to be a common problem with AppImageKit. See also here.

This doesn't play well with my current build system. I can probably fix this with a shell script, but it would be nice if it worked out of the box and showed the same behavior as when using a vanilla installation. I don't know jack about AppImages, but the above links seem to suggest it can be fixed when building the image.

If there is another quick solution other than writing a script to expand the path, I'd love to know.


Edit: here's the solution I came up with (requires bash):

Code: Select all

#!/bin/bash
GAME="$(readlink -f ${@: -1})"
set -- "${@:1:$(($#-1))}"
love-11.1-linux-x86_64.AppImage $@ $GAME
I saved this as /usr/bin/love11, with the AppImage in the executable path. Makes both absolute and relative paths work.

Thanks for the links, it looks like AppImageKit sets the OWD environment variable to the working directory it was called in, I'll probably update the script to switch back to that directory.
