* Prevent adding duplicate bindings
* Clean reverse_map on overwrite or add direct
* Added get_bindings to complement get_binding
* Added doc comments for easier comprehension
* Check if command is function on add_direct
Currently some plugins had/have issues with predicates that check
if active view is a docview to perform certain operations like draw
in the case of minimap or lineguide. Since is() was checking the
entire inheritance tree it was returning true for views that inherit
from the same parent, which caused CommandView to be matched along
DocView, etc... This change does the following to solve the issue:
* Make Object:is() only match the top level parent of the object which
is more in line with what one would expect from a method named 'is'.
* Introduces Object:extends() which keeps the same functionality that
Object:is() offered before.
Using `get_active_node` might result in a locked `Node`; calling
`add_view` on that `Node` throws an error.
`get_active_node_default` always returns an unlocked `Node`.
* Send `mouseleft` event when the mouse leaves the window
* Call `View:on_mouse_left` when the mouse leaves the `View`
Previously `View:on_mouse_left` was called only when the mouse left the
window, and it was called on every visible `View`.
Now it gets also called when the mouse "changes" `View`, and only the
last `View` the mouse was on will receive the event.
Before the addition of multi-cursor support, we just returned the second
return value of the "replacer" function to the caller.
With the introduction of multi-cursors, we naively summed the second
return values for each cursor.
In some cases the "replacer" function doesn't return any second value,
so we tried to do math with `nil`, thus throwing errors.
Now the second return value is added to a table which is then returned
to the caller.
* Change to 1 click as per RFC on discord, with 100% in favour.
* Added in the ability to specify as a view name, so it doesn't modify the title, and also fixed a bug where if you clicked *over* the amount of times your config says, it wouldn't regsiter.
* Changed plugin to use keymap.
This allows `keymap.add` to map shortcuts to functions.
If the function returns `false`, the next command is executed (as if the
`predicate` of a `command` failed).
We color a 1x1 `SDL_Surface` with the desired color. This surface is
then stretched over the area we need to cover using `SDL_BlitScaled`.
This way we avoid having to do the blending ourselves.
