Also, move a few free-standing functions into StoreAPI and Derivation.
Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)
This commit add workspace and X window containers support to avoid using
Emacs frames as the parents of X windows. This should make it easier to
set input focus.
* exwm-core.el (exwm--container, exwm--floating-frame-position): New file
local variables.
(exwm--floating-frame-geometry): Removed file local variable.
* exwm-floating.el (exwm-floating--set-floating)
(exwm-floating--unset-floating, exwm-floating--do-moveresize)
(exwm-floating-move): Use container.
(exwm-floating--fit-frame-to-window): No longer adjust stacking order.
(exwm-floating--fit-frame-to-window): The first member is changed to
buffer.
(exwm-floating--start-moveresize): Use container. Correctly set input
focus.
* exwm-input.el (exwm-input--redirected, exwm-input--on-focus-in): Removed.
(exwm-input--on-buffer-list-update): Remove the restriction on floating
frames which is no longer valid.
(exwm-input--update-focus): Adjust stacking order.
(exwm-input--on-minibuffer-setup): New function for setting focus on the
Emacs frame when entering minibuffer.
(exwm-input--on-KeyPress-line-mode): No longer compensate FocusOut event.
(exwm-input--grab-keyboard, exwm-input--release-keyboard): Local keys are
now grabbed on the X window container.
(exwm-input--init): Add `exwm-input--on-minibuffer-setup' to
`minibuffer-setup-hook'.
* exwm-layout.el (exwm-layout--resize-container): New function to
resize/reposition both the X window and its container.
(exwm-layout--show, exwm-layout--hide): Use container.
(exwm-layout-set-fullscreen): Use container. No longer save width and
height.
(exwm-layout-unset-fullscreen, exwm-layout--set-frame-fullscreen): Use
container.
(exwm-layout--refresh): Update a frame parameter. Remove dead code.
* exwm-manage.el (exwm-manage--manage-window): Reparent unmanaged X windows
to the workspace. Create X window container as the parent of the X window.
(exwm-manage--unmanage-window): Unmap/destroy container when appropriate.
Use the position of container.
(exwm-manage--unmanage-window): Destroy the container.
* exwm-randr.el (exwm-randr--refresh): Resize workspace using container.
* exwm-workspace.el (exwm-workspace-switch): Raise workspace.
Correctly set input focus.
(exwm-workspace--on-focus-in): Removed.
(exwm-workspace-move-window): Reparent to workspace container.
(exwm-workspace--init): Create workspace frames as visible.
Create workspace containers.
Remove exwm-workspace--on-focus-in from focus-in-hook.
Update _NET_VIRTUAL_ROOTS.
* exwm.el (exwm-init): No longer disable hourglass window.
Initialize workspace module before input.
* exwm-core.el (exwm--debug): New macro for setting debug forms.
* exwm-floating.el (exwm-floating--set-floating): No longer do `exwm--lock'
and `exwm--unlock' since `make-frame' is already adviced to take care of
everything. Correctly set input focus to the newly created floating
X window.
* exwm-core.el (exwm--floating-edges): Removed file local variable.
* exwm-floating.el (exwm-floating--set-floating)
(exwm-floating--unset-floating):
* exwm-layout.el (exwm-layout--show, exwm-layout-enlarge-window):
* exwm-manage.el (exwm-manage--on-ConfigureRequest):
No longer use floating geometry.
* exwm-input.el (exwm-input--update-global-prefix-keys): Grab global keys
on workspaces containers instead of the root window (or input focus would
transfer to the workspace containing the pointer when the grab is active).
* exwm-workspace.el (exwm-workspace-switch): No longer move mouse.
For example,
$ nix-build --hash -A nix-repl.src
will build the fixed-output derivation nix-repl.src (a fetchFromGitHub
call), but instead of *verifying* the hash given in the Nix
expression, it prints out the resulting hash, and then moves the
result to its content-addressed location in the Nix store. E.g
build produced path ‘/nix/store/504a4k6zi69dq0yjc0bm12pa65bccxam-nix-repl-8a2f5f0607540ffe56b56d52db544373e1efb980-src’ with sha256 hash ‘0cjablz01i0g9smnavhf86imwx1f9mnh5flax75i615ml71gsr88’
The goal of this is to make all nix-prefetch-* scripts unnecessary: we
can just let Nix run the real thing (i.e., the corresponding fetch*
derivation).
Another example:
$ nix-build --hash -E 'with import <nixpkgs> {}; fetchgit { url = "https://github.com/NixOS/nix.git"; sha256 = "ffffffffffffffffffffffffffffffffffffffffffffffffffff"; }'
...
git revision is 9e7c1a4bbd
...
build produced path ‘/nix/store/gmsnh9i7x4mb7pyd2ns7n3c9l90jfsi1-nix’ with sha256 hash ‘1188xb621diw89n25rifqg9lxnzpz7nj5bfh4i1y3dnis0dmc0zp’
(Having to specify a fake sha256 hash is a bit annoying...)
