From 30c2c8a154e770b3920bcfd7d553825fe9182bf4 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 12:57:47 -0300 Subject: Move the frame into draw.zig and the transitions out of layout.zig Pure moves, no behaviour change. draw.zig holds the whole core frame in order: render, the pane, tag, header and notice painters it calls, and the character-effect composition (Pardes.render stays a declaration alias). Presentation.zig is the panel presentation state as a file struct, and animation.zig the easing curves, transition kinds, tracks and boxes, the character effects' sources and the generic displayed-value transition, all of which lived in layout.zig. layout.zig keeps only layout. --- src/body_layer.zig | 449 ----------------------------------------------------- 1 file changed, 449 deletions(-) (limited to 'src/body_layer.zig') diff --git a/src/body_layer.zig b/src/body_layer.zig index f9e26b10..aa52957c 100644 --- a/src/body_layer.zig +++ b/src/body_layer.zig @@ -555,452 +555,3 @@ pub fn bodyText(p: *Pardes, arena: std.mem.Allocator, pane: *Pane) ![]const u8 { if (pane.file) |*f| return panes.File.bodyText(arena, pane, f, p.settings.wrap); return panes.Terminal.bodyText(arena, pane); } - -/// The workspace and column tags as the grid shows them: their text, the -/// word under the pointer and, in the one being edited, its selection and -/// caret.

The body layer and the tag layers paint straight into their own temporary surfaces, and the std.mem.swap of p.surface around those calls is gone.

The painters read their geometry from it instead of working it out again: the grid's notice chips and the notice layers share one chip rectangle, the rails (file, terminal, image, PDF page) paint the placed thumb (a native PDF measures its own into the region as it places its pages), and the body, tag, notice and column layers take their viewports from their regions. A collapsed pane places only its grip and tag. The column-move rail's one-cell clip of the layers under it is now a region field set in place, not a mutation of the built layers. No behaviour change; a test checks every region against the old geometry, the painted rail and the layer viewports across tag bottom, column tags, notices, a collapsed pane and a multi-line tag. --- src/body_layer.zig | 37 ++------ src/draw.zig | 258 ++++++++++++++++++++++++++++++++++++++++++++--------- src/pardes.zig | 1 + src/pdf_view.zig | 25 ++---- src/surface.zig | 57 ++++++++++++ 5 files changed, 291 insertions(+), 87 deletions(-) (limited to 'src/body_layer.zig') diff --git a/src/body_layer.zig b/src/body_layer.zig index db4d9524..2b6ae773 100644 --- a/src/body_layer.zig +++ b/src/body_layer.zig @@ -279,7 +279,7 @@ pub fn renderBodyLayer(p: *Pardes, arena: std.mem.Allocator, pane: *Pane, r: Rec @memset(temporary_cells, .{});

The grid's caret for a tag, a header or a prompt is the layer's, projected to grid columns. A wide glyph cut by the edge of the copy is left as the band's blank, as the grid's print never drew half of one (a test proves it, and fails without the re-clip). Where the two copies disagreed, the grid's behaviour is kept, so every snapshot golden is byte-identical: - a notice highlighted the hovered word only as a layer; now it never does; - a column tag's hover was suppressed during a column move only on the grid; now in both; - a header under edit showed the hovered word only on the grid; now in both, under the selection; - a notice's leading padding carried the band's ink only as a layer; the grid copy keeps it blank; - a notice whose band is wider in tagline pitch than in grid cells (a GUI core) now shows the band's right end on the grid, where its text is, and its prompt caret there. A sweep begun on a tag and dragged into the body still shows on the body rows it crossed, on the grid only (paintPointerSelection's from_row). --- src/body_layer.zig | 8 +- src/draw.zig | 565 +++++++++++++++++++++++++---------------------------- src/surface.zig | 4 +- 3 files changed, 271 insertions(+), 306 deletions(-) (limited to 'src/body_layer.zig') diff --git a/src/body_layer.zig b/src/body_layer.zig index 2b6ae773..e1a45058 100644 --- a/src/body_layer.zig +++ b/src/body_layer.zig @@ -228,6 +228,8 @@ pub fn paintPointerSelection( tag_y: u16, body_y: u16, sl: Pane.Sel, + /// Rows of the selection above this are left alone. + from_row: u16, bg: [3]u8, fg: ?[3]u8, ) void { @@ -238,7 +240,7 @@ pub fn paintPointerSelection( const c1 = @max(0, @max(sl.c0, sl.c1)); var row: u16 = 0; while (row < r.h) : (row += 1) { - if (@as(i32, row) < r0 or @as(i32, row) > r1) continue; + if (@as(i32, row) < r0 or @as(i32, row) > r1 or row < from_row) continue; const sy = if (row < pane.tag_rows) tag_y + row else body_y + row - pane.tag_rows; // File line numbers occupy a gutter only in the body.

Which rows are context rows is still decided by a text build before the paint, and a body without them reuses that text and paints straight onto the grid: every other body has no row the grid cannot show, so it gets no layer and no copy. Each part now paints only its own rows. The tag paints the tag rows of every pointer sweep that crosses them (the select sweep in the tag's colours, the look-hover affordance over it, a middle or right sweep over both in its button's tint), which the body used to paint over the tag on the grid alone; the body paints only body rows, and a select sweep begun on the tag marks the body rows it crossed before the text is laid down, as it did. Grid and layers agree, the snapshot goldens are byte-identical, and a test checks the joined grid rows and caret against a plain paint of the same body with the tag on top and at the bottom. The GUI goldens gain a terminal pane scene. --- docs/render-pipeline.md | 10 ++++++ src/body_layer.zig | 79 ++++++++++++++++++++++++++++++++----------- src/draw.zig | 90 +++++++++++++++++++++++++++++++++++++------------ test/gui-goldens.txt | 1 + test/gui_golden.py | 8 +++++ 5 files changed, 146 insertions(+), 42 deletions(-) (limited to 'src/body_layer.zig') diff --git a/docs/render-pipeline.md b/docs/render-pipeline.md index 590a7e72..f63b9a0b 100644 --- a/docs/render-pipeline.md +++ b/docs/render-pipeline.md @@ -842,6 +842,16 @@ goldens; ssh/tty byte budgets; wire version bump breaks mixed-version attach. 4.
