Simplify tree_close_internal This commit makes multiple changes in tree_close_internal. I didn't split them because they are not completely independent. - Remove force_set_focus parameter This parameter was always set to `false` throughout the code base except for one case where it was set to `(con == focused)`, when killing a floating con's parent (the one with type CT_FLOATING_CON). But this case is not needed anymore since the special handling of CT_FLOATING_CONs in con_next_focused was removed in #2941. - Assume that con_next_focused does not returned a container of type CT_DOCKAREA. This is reasonable since con_next_focused uses the focus_head stack and has special handling of CT_DOCKAREA containers. - Remove is_mapped This variable was only used in the if block towards the end of tree_close_internal. Ignoring the, now removed, dockarea code and the use of force_set_focus this block performed only one useful action: focus the `next` container when `con == focused`. `con == focused` was a necessary and sufficient condition for the con_activate call: if `con != focused` we could reach the inner if blocks because of the other conditions but would never focus another container. If `con == focused` then all other conditions would be irrelevant. - Remove special handling of floating containers Since the `next` focused container is calculated through the parent for floating containers, I moved this code to con_next_focused. Also, because of the removal of force_set_focus, it appears that we can call con_on_remove_child for floating containers as well.

Introduce splith/splitv layouts, remove orientation With this commit, the "default" layout is replaced by the splith and splitv layouts. splith is equivalent to default with orientation horizontal and splitv is equivalent to default with orientation vertical. The "split h" and "split v" commands continue to work as before, they split the current container and you will end up in a split container with layout splith (after "split h") or splitv (after "split v"). To change a splith container into a splitv container, use either "layout splitv" or "layout toggle split". The latter command is used in the default config as mod+l (previously "layout default"). In case you have "layout default" in your config file, it is recommended to just replace it by "layout toggle split", which will work as "layout default" did before when pressing it once, but toggle between horizontal/vertical when pressing it repeatedly. The rationale behind this commit is that it’s cleaner to have all parameters that influence how windows are rendered in the layout itself rather than having a special parameter in combination with only one layout. This enables us to change existing split containers in all cases without breaking existing features (see ticket #464). Also, users should feel more confident about whether they are actually splitting or just changing an existing split container now. As a nice side-effect, this commit brings back the "layout toggle" feature we once had in i3 version 3 (see the userguide). AFAIK, it is safe to use in-place restart to upgrade into versions after this commit (switching to an older version will break your layout, though). Fixes #464

Introduce splith/splitv layouts, remove orientation With this commit, the "default" layout is replaced by the splith and splitv layouts. splith is equivalent to default with orientation horizontal and splitv is equivalent to default with orientation vertical. The "split h" and "split v" commands continue to work as before, they split the current container and you will end up in a split container with layout splith (after "split h") or splitv (after "split v"). To change a splith container into a splitv container, use either "layout splitv" or "layout toggle split". The latter command is used in the default config as mod+l (previously "layout default"). In case you have "layout default" in your config file, it is recommended to just replace it by "layout toggle split", which will work as "layout default" did before when pressing it once, but toggle between horizontal/vertical when pressing it repeatedly. The rationale behind this commit is that it’s cleaner to have all parameters that influence how windows are rendered in the layout itself rather than having a special parameter in combination with only one layout. This enables us to change existing split containers in all cases without breaking existing features (see ticket #464). Also, users should feel more confident about whether they are actually splitting or just changing an existing split container now. As a nice side-effect, this commit brings back the "layout toggle" feature we once had in i3 version 3 (see the userguide). AFAIK, it is safe to use in-place restart to upgrade into versions after this commit (switching to an older version will break your layout, though). Fixes #464

Introduce splith/splitv layouts, remove orientation With this commit, the "default" layout is replaced by the splith and splitv layouts. splith is equivalent to default with orientation horizontal and splitv is equivalent to default with orientation vertical. The "split h" and "split v" commands continue to work as before, they split the current container and you will end up in a split container with layout splith (after "split h") or splitv (after "split v"). To change a splith container into a splitv container, use either "layout splitv" or "layout toggle split". The latter command is used in the default config as mod+l (previously "layout default"). In case you have "layout default" in your config file, it is recommended to just replace it by "layout toggle split", which will work as "layout default" did before when pressing it once, but toggle between horizontal/vertical when pressing it repeatedly. The rationale behind this commit is that it’s cleaner to have all parameters that influence how windows are rendered in the layout itself rather than having a special parameter in combination with only one layout. This enables us to change existing split containers in all cases without breaking existing features (see ticket #464).

Simplify tree_close_internal This commit makes multiple changes in tree_close_internal. I didn't split them because they are not completely independent. - Remove force_set_focus parameter This parameter was always set to `false` throughout the code base except for one case where it was set to `(con == focused)`, when killing a floating con's parent (the one with type CT_FLOATING_CON). But this case is not needed anymore since the special handling of CT_FLOATING_CONs in con_next_focused was removed in #2941. - Assume that con_next_focused does not returned a container of type CT_DOCKAREA. This is reasonable since con_next_focused uses the focus_head stack and has special handling of CT_DOCKAREA containers. - Remove is_mapped This variable was only used in the if block towards the end of tree_close_internal. Ignoring the, now removed, dockarea code and the use of force_set_focus this block performed only one useful action: focus the `next` container when `con == focused`. `con == focused` was a necessary and sufficient condition for the con_activate call: if `con != focused` we could reach the inner if blocks because of the other conditions but would never focus another container. If `con == focused` then all other conditions would be irrelevant. - Remove special handling of floating containers Since the `next` focused container is calculated through the parent for floating containers, I moved this code to con_next_focused. Also, because of the removal of force_set_focus, it appears that we can call con_on_remove_child for floating containers as well.

con_set_layout: always use the parent container, handle workspaces properly Previously, in case 'layout stacked' (for example) had been called interactively, con_set_layout would be called with focused->parent, while with for_window, it’d be called on the actual matching container. This difference in behavior was the cause for the inability to use 'for_window [class="XTerm"] layout tabbed', which now works \o/, but more on that below. The change also allows us to handle the case of the user selecting a CT_WORKSPACE container properly, that is, by using the special case and creating a new split container on the workspace which gets all the contents, but a new layout.

Therefore, to open XTerm in its own tabbed split container, you need to split before: for_window [class="XTerm"] split v, layout tabbed The comma here is important!

Introduce splith/splitv layouts, remove orientation With this commit, the "default" layout is replaced by the splith and splitv layouts. splith is equivalent to default with orientation horizontal and splitv is equivalent to default with orientation vertical. The "split h" and "split v" commands continue to work as before, they split the current container and you will end up in a split container with layout splith (after "split h") or splitv (after "split v"). To change a splith container into a splitv container, use either "layout splitv" or "layout toggle split". The latter command is used in the default config as mod+l (previously "layout default"). In case you have "layout default" in your config file, it is recommended to just replace it by "layout toggle split", which will work as "layout default" did before when pressing it once, but toggle between horizontal/vertical when pressing it repeatedly. The rationale behind this commit is that it’s cleaner to have all parameters that influence how windows are rendered in the layout itself rather than having a special parameter in combination with only one layout. This enables us to change existing split containers in all cases without breaking existing features (see ticket #464). Also, users should feel more confident about whether they are actually splitting or just changing an existing split container now. As a nice side-effect, this commit brings back the "layout toggle" feature we once had in i3 version 3 (see the userguide). AFAIK, it is safe to use in-place restart to upgrade into versions after this commit (switching to an older version will break your layout, though). Fixes #464

con_set_layout: always use the parent container, handle workspaces properly Previously, in case 'layout stacked' (for example) had been called interactively, con_set_layout would be called with focused->parent, while with for_window, it’d be called on the actual matching container. This difference in behavior was the cause for the inability to use 'for_window [class="XTerm"] layout tabbed', which now works \o/, but more on that below. The change also allows us to handle the case of the user selecting a CT_WORKSPACE container properly, that is, by using the special case and creating a new split container on the workspace which gets all the contents, but a new layout. Now, before you are enthusiastic about the change and try to use for_window magic in your config file, keep in mind: The 'layout' command acts on the parent split container. That is, when using a line such as this one: for_window [class="XTerm"] layout tabbed …and opening an XTerm when on a workspace with one single other window, the whole workspace will be set tabbed (just as previously when you opened an XTerm and sent 'layout tabbed' manually). Therefore, to open XTerm in its own tabbed split container, you need to split before: for_window [class="XTerm"] split v, layout tabbed The comma here is important! It says that the second command should not be treated as an entirely unrelated command, but it should also relate the matching window (while it does work with a ';', that is prone to race-conditions and should be avoided). fixes #358

Simplify tree_close_internal This commit makes multiple changes in tree_close_internal. I didn't split them because they are not completely independent. - Remove force_set_focus parameter This parameter was always set to `false` throughout the code base except for one case where it was set to `(con == focused)`, when killing a floating con's parent (the one with type CT_FLOATING_CON). But this case is not needed anymore since the special handling of CT_FLOATING_CONs in con_next_focused was removed in #2941. - Assume that con_next_focused does not returned a container of type CT_DOCKAREA. This is reasonable since con_next_focused uses the focus_head stack and has special handling of CT_DOCKAREA containers. - Remove is_mapped This variable was only used in the if block towards the end of tree_close_internal. Ignoring the, now removed, dockarea code and the use of force_set_focus this block performed only one useful action: focus the `next` container when `con == focused`. `con == focused` was a necessary and sufficient condition for the con_activate call: if `con != focused` we could reach the inner if blocks because of the other conditions but would never focus another container. If `con == focused` then all other conditions would be irrelevant. - Remove special handling of floating containers Since the `next` focused container is calculated through the parent for floating containers, I moved this code to con_next_focused. Also, because of the removal of force_set_focus, it appears that we can call con_on_remove_child for floating containers as well.
