From d6cd79c342495738fc23fbfbf19a01e73cdc42dc Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Fri, 17 Aug 2018 19:48:34 +1000 Subject: [PATCH] Implement iterators per container type This introduces the following `for_each` functions: * root_for_each_workspace * root_for_each_container * output_for_each_workspace * output_for_each_container * workspace_for_each_container And introduces the following `find` functions: * root_find_output * root_find_workspace * root_find_container * output_find_workspace * output_find_container * workspace_find_container * container_find_child And removes the following functions: * container_descendants * container_for_each_descendant * container_find This change is preparing the way for demoting sway_container. Eventually these functions will accept and return sway_outputs, sway_workspaces and sway_containers (meaning a C_CONTAINER or C_VIEW). This change also makes it easy to handle abnormalities like the workspace floating list, root's scratchpad list and (once implemented) root's saved workspaces list for when there's no connected outputs. --- include/sway/output.h | 12 +++++ include/sway/tree/container.h | 11 +---- include/sway/tree/root.h | 15 ++++++ include/sway/tree/workspace.h | 6 +++ sway/commands/hide_edge_borders.c | 2 +- sway/commands/show_marks.c | 3 +- sway/commands/swap.c | 6 +-- sway/commands/unmark.c | 3 +- sway/config.c | 13 +----- sway/criteria.c | 15 +----- sway/desktop/output.c | 9 ++-- sway/input/seat.c | 6 +-- sway/ipc-server.c | 8 ++-- sway/tree/container.c | 62 +++++++++--------------- sway/tree/output.c | 52 ++++++++++++++++++++- sway/tree/root.c | 78 +++++++++++++++++++++++++++++++ sway/tree/view.c | 6 +-- sway/tree/workspace.c | 71 ++++++++++++++++++++++++---- 18 files changed, 268 insertions(+), 110 deletions(-) diff --git a/include/sway/output.h b/include/sway/output.h index 8bdd1919..d0d034b3 100644 --- a/include/sway/output.h +++ b/include/sway/output.h @@ -95,4 +95,16 @@ void output_drag_icons_for_each_surface(struct sway_output *output, struct wl_list *drag_icons, sway_surface_iterator_func_t iterator, void *user_data); +void output_for_each_workspace(struct sway_container *output, + void (*f)(struct sway_container *con, void *data), void *data); + +void output_for_each_container(struct sway_container *output, + void (*f)(struct sway_container *con, void *data), void *data); + +struct sway_container *output_find_workspace(struct sway_container *output, + bool (*test)(struct sway_container *con, void *data), void *data); + +struct sway_container *output_find_container(struct sway_container *output, + bool (*test)(struct sway_container *con, void *data), void *data); + #endif diff --git a/include/sway/tree/container.h b/include/sway/tree/container.h index d866ec03..c8410801 100644 --- a/include/sway/tree/container.h +++ b/include/sway/tree/container.h @@ -214,15 +214,11 @@ struct sway_container *container_destroy(struct sway_container *container); struct sway_container *container_close(struct sway_container *container); -void container_descendants(struct sway_container *root, - enum sway_container_type type, - void (*func)(struct sway_container *item, void *data), void *data); - /** * Search a container's descendants a container based on test criteria.
