This adds dot files into the finder. We are adding the overrides to the
`ignore` package, that can be used later to add custom ignore
directories that can be passed in as settings.
We are also adding a new `ivy_cwd` function to libivy to get the current
directory due to the limitations of lua.
Fixes-issue: #16
The API for `window.set_items` took to many variable types. It would
take a table in multiple different formats and a string. Now it will
only take a table in a single format and a string. It will convert the
string into the table format by splitting it on new lines.
The table format is an array of tables that must have a `content` key
that will be the text that is displayed in the completion window. The
table can have any other data that is ignored.
```lua
local items = {
{ content = "Item one" },
{ content = "Item two" }
}
```
The `set_items` function will only display the `content` key in the
completion window, it will not do any sorting or filtering, that must be
done before passing the data to the `set_items` function.
Now the prompt will act like the default bash readline with emacs key
bindings, clear and delete word.
You can now also move left and right in the prompt to insert chars in
the middle of the prompt rather than having to delete your search term
and start again.
This will allow you to get the buffer the user was on when they invoked
an ivy command. This buffer is called the `origin` and you can access it
with `vim.ivy.origin()`.
Large projects can take a long time for the initial scan. This adds some
loading text until the initial selection has completed.
This will also now schedule the work to collect and sort the candidates
to ensure the UI is rendered before with work begins and creates a
hanging user experience.
