When `UndoManager.transact` is called with no function, you later need
to `abort` or `commit` the transaction manually. This allows
transactions to last longer than the dynamic scope of the single
function passed to `transact`.
Also, add a spec to cover the loading of keymaps in `atom-spec` and
reset the `keymap`'s internal data after each spec gets run to prevent
test pollution with keymaps.
This prevents autosave from writing unmodified buffers to disk, which
was causing the tree view to rebuild directory contents based on the
write event just when switching tabs.
TextMatePackage is only designed to load resources out of a TextMate
bundle. It's used only at load time, and from that point out we only
refer to our own global `syntax` data structure to access the data that
it loads.
These changes are mostly aesthetic in nature. I just thought it would
be a good idea to have theme loading be parallel to package loading as
much as possible. So I localized more logic on the `atom` global.
There's a slight wrinkle in this commit… TextMate grammars sometimes store
the `foldStopMarker` directly in the grammar, rather than storing it
in a separate scoped preferences file like the other settings. So we
have to scan through grammars looking for those that have the fold end
marker and make a scoped property for that grammar's scope.
This corrects a regression when pattern matching
to the newline was added.
If the newline is never matched the loop still needs to
terminated so now when the position is before the newline
and the last match had no tokens the loop is broken out of.
This makes the scoped property system mimic the behavior of CSS. When
there is a tie, the scoped properties loaded later in the cascade win.
I also optimize the scanning of all the properties, checking only those
sets of properties that have a value for the desired key path, to reduce
the need to match a ton of scope selectors.
We'll store all syntax-related global state in the `syntax` global. For
now, this means that all scoped properties will be stored here, as well
as all grammars.
Previously no gutter highlight was displayed unless
the selection was empty.
Now there is a separate CSS class for no selection
that changes the background color independently
from the foreground color.
You can pass a scope stack when calling `config.get`, which will prefer
settings under the most specific matching scope selector for the given
scope stack.
This simplifies the loading of TextMate bundles in the spec and benchmark helpers. Since `loadBundle` was already implemented on `atom`, it made sense to move this logic here. Config is now more focused on its core job of handling configuration, not loading bundles.
