From 22ac1c121ab1ed09ab82ed1586fdaf725823305c Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Mon, 14 Jan 2019 19:03:32 +1000 Subject: Replace resize_axis with wlr_edges This patch removes the resize_axis enum in favour of wlr_edges. As wlr_edges has no `horizontal` or `vertical` value, it denotes these by bitwise `or`ing the left/right and up/down values. Two constants are defined to make it easier to refer to these. This will allow the tiling resize seatop to utilise the functions in this file. resize_axis was local to the resize command and couldn't be exposed in function arguments. --- sway/commands/resize.c | 161 +++++++++++++++---------------------------------- 1 file changed, 47 insertions(+), 114 deletions(-) (limited to 'sway') diff --git a/sway/commands/resize.c b/sway/commands/resize.c index cf5dea02..bcec2c9d 100644 --- a/sway/commands/resize.c +++ b/sway/commands/resize.c @@ -13,6 +13,9 @@ #include "sway/tree/workspace.h" #include "log.h" +#define AXIS_HORIZONTAL (WLR_EDGE_LEFT | WLR_EDGE_RIGHT) +#define AXIS_VERTICAL (WLR_EDGE_TOP | WLR_EDGE_BOTTOM) + static const int MIN_SANE_W = 100, MIN_SANE_H = 60; enum resize_unit { @@ -22,16 +25,6 @@ enum resize_unit { RESIZE_UNIT_INVALID, }; -enum resize_axis { - RESIZE_AXIS_HORIZONTAL, - RESIZE_AXIS_VERTICAL, - RESIZE_AXIS_UP, - RESIZE_AXIS_DOWN, - RESIZE_AXIS_LEFT, - RESIZE_AXIS_RIGHT, - RESIZE_AXIS_INVALID, -}; - struct resize_amount { int amount; enum resize_unit unit; @@ -111,61 +104,48 @@ static void calculate_constraints(int *min_width, int *max_width, } } -static enum resize_axis parse_resize_axis(const char *axis) { +static enum wlr_edges parse_resize_axis(const char *axis) { if (strcasecmp(axis, "width") == 0 || strcasecmp(axis, "horizontal") == 0) { - return RESIZE_AXIS_HORIZONTAL; + return AXIS_HORIZONTAL; } if (strcasecmp(axis, "height") == 0 || strcasecmp(axis, "vertical") == 0) { - return RESIZE_AXIS_VERTICAL; + return AXIS_VERTICAL; } if (strcasecmp(axis, "up") == 0) { - return RESIZE_AXIS_UP; + return WLR_EDGE_TOP; } if (strcasecmp(axis, "down") == 0) { - return RESIZE_AXIS_DOWN; + return WLR_EDGE_BOTTOM; } if (strcasecmp(axis, "left") == 0) { - return RESIZE_AXIS_LEFT; + return WLR_EDGE_LEFT; } if (strcasecmp(axis, "right") == 0) { - return RESIZE_AXIS_RIGHT; + return WLR_EDGE_RIGHT; } - return RESIZE_AXIS_INVALID; + return WLR_EDGE_NONE; } -static enum resize_axis normalize_axis(enum resize_axis axis) { - switch (axis) { - case RESIZE_AXIS_HORIZONTAL: - case RESIZE_AXIS_LEFT: - case RESIZE_AXIS_RIGHT: - return RESIZE_AXIS_HORIZONTAL; - case RESIZE_AXIS_VERTICAL: - case RESIZE_AXIS_UP: - case RESIZE_AXIS_DOWN: - return RESIZE_AXIS_VERTICAL; - case RESIZE_AXIS_INVALID: - sway_assert(false, "Never reached"); - } - sway_assert(false, "Never reached"); - return RESIZE_AXIS_INVALID; +static bool is_horizontal(enum wlr_edges axis) { + return axis & (WLR_EDGE_LEFT | WLR_EDGE_RIGHT); } -static int parallel_coord(struct sway_container *c, enum resize_axis a) { - return normalize_axis(a) == RESIZE_AXIS_HORIZONTAL ? c->x : c->y; +static int parallel_coord(struct sway_container *c, enum wlr_edges axis) { + return is_horizontal(axis) ? c->x : c->y; } -static int parallel_size(struct sway_container *c, enum resize_axis a) { - return normalize_axis(a) == RESIZE_AXIS_HORIZONTAL ? c->width : c->height; +static int parallel_size(struct sway_container *c, enum wlr_edges axis) { + return is_horizontal(axis) ? c->width : c->height; } static void container_recursive_resize(struct sway_container *container, double amount, enum wlr_edges edge) { bool layout_match = true; wlr_log(WLR_DEBUG, "Resizing %p with amount: %f", container, amount); - if (edge == WLR_EDGE_LEFT || edge == WLR_EDGE_RIGHT) { + if (edge & (WLR_EDGE_LEFT | WLR_EDGE_RIGHT)) { container->width += amount; layout_match = container->layout == L_HORIZ; - } else if (edge == WLR_EDGE_TOP || edge == WLR_EDGE_BOTTOM) { + } else if (edge & (WLR_EDGE_TOP | WLR_EDGE_BOTTOM)) { container->height += amount; layout_match = container->layout == L_VERT; } @@ -180,14 +160,14 @@ static void container_recursive_resize(struct sway_container *container, } static void resize_tiled(struct sway_container *parent, int amount, - enum resize_axis axis) { + enum wlr_edges axis) { struct sway_container *focused = parent; if (!parent) { return; } enum sway_container_layout parallel_layout = - normalize_axis(axis) == RESIZE_AXIS_HORIZONTAL ?
