This moves the config parsing from out of alpm and into the
go-pacmanconf libary plus some boilerplate code to get it into our alpm
config.
This makes sense as many config options such as UseColor and CleanMethod
have nothing to do with alpm and only relate to pacman.
pacman-conf is used instead of direct config parsing. This tool resolves
defaults and includes for us, so we don't need to handle it.
It is now safe to drop all the config parsing from go-alpm.
Most programs seem to take an empty string as being the same as unset.
Even if they are technically different. This makes it easier to unset
variables via `VARIABLE= yay --foo`.
Split functions out into smaller, more simple chunks. Ensure the correct
order of things.
Before, initConfig() would also create config.BuildDirbefore
the command line flags have been applied, so yay would
try to mkdir what was in the config, ignoring the flag.
Normaly we only pass --config to pacman if the user specifies it on the
command line. Otherwise we let pacman use it's default config location.
If the user has changed pacmanconf in Yay's config file then this could
cause a miss match between the config we use to init alpm and the config
pacman is using.
Currently When performing a system upgrade, Yay will first refresh the
database then perform the repo and AUR upgrade. This allows Yay to add
some features such as better batch interaction, showing potential
dependency problems before the upgrade starts and combined menus
showing AUR and repo upgrades together.
There has been discussion that this approach is a bad idea. The main issue
people have is that the separation of the database refresh and the upgrade
could lead to a partial upgrade if Yay fails between the two stages.
Personally I do not like this argument, there are valid reasons to Yay
to fail between these points. For example there may be dependency or
conflict issues during the AUR upgrade. Yay can detect these before any
installing actually starts and exit, just like how pacman will when
there are dependency problems.
If Yay does fail between these points, for the previously mentioned
reasons or even a crash then a simple refresh will not cause a
partial upgrade by itself. It is then the user's responsibility
to either resolve these issues or instead perform an upgrade using
pacman directly.
My opinions aside, The discussions on the Arch wiki has reached
a decision, this method is not recommended. So to follow the decided
best practises this behaviour has been disabled by default.
This behaviour can be toggled using the --[no]combinedupgrade flag
It should be noted that Yay's upgrade menu will not show repo packages
unless --combinedupgrade is used.
There were several calls to fmt.Errorf in setPaths where the returned error was not
being used. This was indicated by ```make test``` as shown here:
```
make test
gofmt -l *.go
go vet
./main.go:16: result of fmt.Errorf call not used
./main.go:21: result of fmt.Errorf call not used
./main.go:25: result of fmt.Errorf call not used
./main.go:30: result of fmt.Errorf call not used
./main.go:35: result of fmt.Errorf call not used
./main.go:39: result of fmt.Errorf call not used
make: *** [Makefile:43: test] Error 2
```
With these changes the tests now all pass with no errors.
Check if enviroment variables are set instead if they are empty strings.
Don't care if the dir exists just take the path at face value.
Error if $HOME and the respective $XDG.. variables are not set.
