need to update binary path in .plist after upgrade
gperciva opened this issue · comments
Looks like the .plist hard-codes the version-specific path, i.e.
/usr/local/Cellar/tarsnap-gui/1.0/Tarsnap.app/Contents/MacOS/Tarsnap
We'll need to update this when there's a new version, or (probably better) make sure that we get the symlink to that file rather than the path itself. (I assume that brew sets up something like /usr/local/bin/tarsnap -> /usr/local/Cellar/tarsnap-gui/1.0/Tarsnap.app/Contents/MacOS/Tarsnap )

This is being addressed in #196 (that PR still needs to add launchd unload ... && launchd load ...).

If you use the opt prefix it won't break across upgrades, and indeed, will keep working if people unlink tarsnap-gui from HOMEBREW_PREFIX for whatever reason. Opt prefix is HOMEBREW_PREFIX/opt/tarsnap-gui, with HOMEBREW_PREFIX usually being /usr/local.
FWIW, as long as the formula is installed, brew --prefix <xyz> will always return the unversioned symlink rather than the versioned path.
