2018-09-05Implement type safe arguments and demote sway_containerRyan Dwyer
This commit changes the meaning of sway_container so that it only refers to layout containers and view containers. Workspaces, outputs and the root are no longer known as containers. Instead, root, outputs, workspaces and containers are all a type of node, and containers come in two types: layout containers and view containers. In addition to the above, this implements type safe variables. This means we use specific types such as sway_output and sway_workspace instead of generic containers or nodes. However, it's worth noting that in a few places places (eg. seat focus and transactions) referring to them in a generic way is unavoidable which is why we still use nodes in some places. If you want a TL;DR, look at node.h, as well as the struct definitions for root, output, workspace and container. Note that sway_output now contains a workspaces list, and workspaces now contain a tiling and floating list, and containers now contain a pointer back to the workspace. There are now functions for seat_get_focused_workspace and seat_get_focused_container. The latter will return NULL if a workspace itself is focused. Most other seat functions like seat_get_focus and seat_set_focus now accept and return nodes. In the config->handler_context struct, current_container has been replaced with three pointers: node, container and workspace. node is the same as what current_container was, while workspace is the workspace that the node resides on and container is the actual container, which may be NULL if a workspace itself is focused. The global root_container variable has been replaced with one simply called root, which is a pointer to the sway_root instance. The way outputs are created, enabled, disabled and destroyed has changed. Previously we'd wrap the sway_output in a container when it is enabled, but as we don't have containers any more it needs a different approach. The output_create and output_destroy functions previously created/destroyed the container, but now they create/destroy the sway_output. There is a new function output_disable to disable an output without destroying it. Containers have a new view property. If this is populated then the container is a view container, otherwise it's a layout container. Like before, this property is immutable for the life of the container. Containers have both a `sway_container *parent` and `sway_workspace *workspace`. As we use specific types now, parent cannot point to a workspace so it'll be NULL for containers which are direct children of the workspace. The workspace property is set for all containers, except those which are hidden in the scratchpad as they have no workspace. In some cases we need to refer to workspaces in a container-like way. For example, workspaces have layout and children, but when using specific types this makes it difficult. Likewise, it's difficult for a container to get its parent's layout when the parent could be another container or a workspace. To make it easier, some helper functions have been created: container_parent_layout and container_get_siblings. container_remove_child has been renamed to container_detach and container_replace_child has been renamed to container_replace. `container_handle_fullscreen_reparent(con, old_parent)` has had the old_parent removed. We now unfullscreen the workspace when detaching the container, so this function is simplified and only needs one argument now. container_notify_subtree_changed has been renamed to container_update_representation. This is more descriptive of its purpose. I also wanted to be able to call it with whatever container was changed rather than the container's parent, which makes bubbling up to the workspace easier. There are now state structs per node thing. ie. sway_output_state, sway_workspace_state and sway_container_state. The focus, move and layout commands have been completely refactored to work with the specific types. I considered making these a separate PR, but I'd be backporting my changes only to replace them again, and it's easier just to test everything at once.
2018-08-31Don't send never-ending transactions when a focused layer surface commitsRyan Dwyer
This moves the arrange_windows call into the arrange_layers function, where we know the output actually needs to be arranged. Additionally, we shouldn't set focus to the parent of an unknown container type, because the parent may be an output and this causes a crash because outputs can't have direct focus. Fixes #2543
2018-08-26Remove layout.cRyan Dwyer
When we have type safety we'll need to have functions for workspace_add_tiling and so on. This means the existing container functions will be just for containers, so they are being moved to container.c. At this point layout.c doesn't contain much else, so I've relocated everything and removed the file. * container_swap and its static functions have been moved to the swap command and made static. * container_recursive_resize has been moved to the resize command and made static. * The following have been moved to container.c: * container_handle_fullscreen_reparent * container_insert_child * container_add_sibling * container_add_child * container_remove_child * container_replace_child * container_split * enum movement_direction and sway_dir_to_wlr have been moved to util.c. Side note: Several commands included layout.h which then included root.h. With layout.h gone, root.h has to be included by those commands.

2018-07-14Simplify transactions by utilising a dirty flag on containersRyan Dwyer
This PR changes the way we handle transactions to a more simple method. The new method is to mark containers as dirty from low level code (eg. arranging, or container_destroy, and eventually seat_set_focus), then call transaction_commit_dirty which picks up those containers and runs them through a transaction. The old methods of using transactions (arrange_and_commit, or creating one manually) are now no longer possible. The highest-level code (execute_command and view implementation handlers) will call transaction_commit_dirty, so most other code just needs to set containers as dirty. This is done by arranging, but can also be done by calling container_set_dirty.

2018-06-26layer_shell: order destroying before sway_outputDominique Martinet
Both sway_output and sway_layer_shell listen to wlr's output destroy event, but sway_layer_shell needs to access into sway_output's data strucure and needs to be destroyed first. Resolve this by making sway_layer_shell listen to a new event that happens at start of sway_output's destroy handler

2018-06-09Refactor everything that needs to arrange windowsRyan Dwyer
* The arrange_foo functions are now replaced with arrange_and_commit, or with manually created transactions and arrange_windows x2. * The arrange functions are now only called from the highest level functions rather than from both high level and low level functions. * Due to the previous point, view_set_fullscreen_raw and view_set_fullscreen are both merged into one function again. * Floating and fullscreen are now working with transactions.

Before freeing sway_output, NULL the wlr_output reference to it. Check for that NULL in layer_shell handle_destroy. Don't damage null container in unmap. Additionaly, terminate swaybg if its output is being disabled.
2018-04-28Refactor arrange_windows()Ryan Dwyer
Replaces arrange_windows() with arrange_root(), arrange_output(), arrange_workspace() and arrange_children_of(). Also makes fullscreen views save and restore their dimensions, which allows it to preserve any custom resize and is also a requirement for floating views once they are implemented.
