This way the disk barely needs to be accessed when loading GitJournal,
and we can hide how long it takes GitJournal to parse all the notes in
the background.
Fixes#78
This is probably the largest commit that I have ever made. From now on -
every File always has an mtime and ctime which is fetched from git.
Notes can optionally override that time by providing yaml metadata.
Additionally the 'filePath' and 'folderPath' is now relative to the
repoPath instead of being the full path.
This will slow down GitJournal like crazy as all the mtimes and ctime
still need to be cached. For my test repo it takes about 23 seconds for
GitJournal to become responsive.
Instead there is a new type called 'UnopenedFile'. This was part of my
effort to not have everything inside the 'Note' class and to make it a
bit more immutable.
But, wow, this took a very long time. The 'Note' class seems to be very
deeply integrated everywhere.
Platform from dart:io cannot be used on the web for reasons. And this
way we get a fake File/Directory class which we can use for atleast
running the web version, even if it won't work.
Stop it being a singleton. This means it needs to be passed around a
lot. This sucks, but it's how it should be. I shouldn't be using a
global variable to get around this.
This is needed as Settings will soon become repo specific when we
support multiple repos.
This breaks saving the settings in a file, that feature was toggled off
anyway. It needs to be thought over again.
It doesn't make any difference as -
1. The sort order shown our SortedNotesFolder is different
2. Rebuilds of the tree affect everything. Even the elements which
should be in the correct place.
This is just for optimizing the loading of the Notes in the correct
order. I want to avoid the notes appearing and disappearing in a strange
order when loading. It gives a bad first impression.
This cache isn't integrated, it's only half done.
