A new chapter, src/devtools. ConnectionManager lists saved connections
with their engine and address, or why one failed, and connects on Enter;
ConnectionForm fills a connection with a port checked from 1 to 65535,
tests it and saves it. SchemaTree shows schemas, tables, views and
fields with keys marked; ERDiagram draws tables and their foreign keys
on NodeGraph, whose fixed wires show only the sockets that hold one.
QueryHistory finds past runs and runs one again; QueryPlanViewer shows
each step's share of the cost. TableStructureEditor edits fields in
place; IndexManager lists and draws up indexes; RedisKeyBrowser finds
keys by glob and lays out each type. QueryEditor is editor::CodeEditor,
whose lexer now knows SQL's words, and QueryResultGrid is
tables::DataGrid. lists::row_action keeps a row's button its own.
writing::begin records the owner's focus, the mind map's or the tool
layer's, through forms::Editing::returning. The field keeps its words on
Enter's release and drops them on Escape, and both hand focus back, so
the map's arrows and the board's Backspace work at once after a write.
Tab in a mind map topic being rewritten keeps the words and hands focus
back to the map; it asks for no child while the field is open, and the
map's keys wait for the field. Tests cover a new wire into a wired input
replacing the old, a connector released on its own shape linking
nothing, and a deleted whiteboard shape taking its links with it.
NodeGraph joins Nodes by wires between typed Ports: a title drags a
node, a drag out of an output lands on an input of the same kind, an
input takes one wire, and a press on a wired input lifts its wire.
Links join shapes on the plane and follow them, straight or at right
angles, with an arrow and words; the Connector tool draws them and the
Note tool drops a sticky note. A double press with Select writes on a
shape. FlowChart draws Steps as ellipses, boxes and diamonds with their
words. MindMap lays topics out from a root, half to each side, and asks
the owner to add, remove and rename by key. Whiteboard keeps its own
tool, view and selection over a board it hands back after each change.
Painting moves to canvas::paint; a press on the tool layer goes through
canvas::press, and the layer focuses itself and asks to delete.
LayerPanel lists the canvas's layers topmost first on lists::Tree: a box
shows or hides each, F2 renames, a drag restacks into a new paint order.
InspectorPanel edits the one selected shape's frame, fill, visibility and
lock. AlignmentToolbar lines up or spreads the selection through
`aligned`. AssetPanel finds shapes by name in a picks grid, each drawn
to fit its tile. ColorPanel, ShadowEditor, BorderEditor and
TypographyPanel edit a look; GradientPanel is forms::GradientEditor.
ConstraintsEditor pins a shape to its frame, with `Constraints::placed`;
AutoLayoutControls sets flow, gap, padding and a place grid, with
`AutoLayout::laid`; ExportPanel names each file once. The panels share
`canvas::panel`: editing, pair, caption, heading and color_well.
Handles resize one shape, so a selection of several shows its outline
and no handles; a press there no longer falls through to a marquee.
ToggleGroup wraps its faces when narrow, so the ToolPalette stays in a
280px box. A pen path left open ends when the tool changes: two points
or more go to the owner after the frame, a lone point is dropped, and
the open path paints only while the pen is the tool.
ToolLayer lies over an InfiniteCanvas and carries its tools. Select
takes the topmost shape a press reaches, Shift adds or drops one, a
drag moves the selection and snaps its nearest edge or middle to
another shape's within reach, a handle resizes it, Shift keeping a
corner's shape, and a drag on empty space draws a SelectionBox that
takes what lies wholly inside. The shape tools draw by a drag toward
any corner, Shift keeping them square; the pen adds a point per press
and a double press ends the path; text drops a line where pressed; the
brush strokes a path its width. A drag may end in the layer or out of
it; each gesture ends once and asks the owner. SelectionBox,
TransformHandles and SnapIndicator draw the marks.
ToolPalette picks a tool from icons named in tips; BrushSettings sets a
brush's width and hue; HistoryPanel lists the steps done, the undone
ones quiet, and takes the drawing to a step on Enter or a double press.
The model changes: lines and arrows end at a named corner, so they run
either way, and paths carry their width. Three Lucide icons: hexagon,
slash and move-up-right.
A wheel without a modifier now slides the content by its delta, as
gpui's scroll boxes do; it moved the other way. The wheel reads the
live viewport and skips an end with no delta, and a drag pans from the
press by the pointer's whole way with the viewport held at the press,
so events that land in one frame no longer overwrite each other. Tests:
a plain wheel moves the content up with it; three wheels and an empty
end add up, and four moves pan their sum; a small frame fits at a zoom
of one.
A new chapter, src/canvas. InfiniteCanvas lays artboards, shapes and
guides on an endless plane over a dot grid whose step, one, two or five
times a power of ten, keeps the dots apart as it zooms out. Rulers run
along the top and left in canvas units. A drag on empty space pans from
the press, a wheel scrolls, and Command or Control with the wheel zooms
about the pointer; the owner keeps the viewport, seeded, so its own
zoom shows at once. Layers lie over the plane in view pixels.
Shapes are rectangles, ellipses, regular polygons, lines, arrows, text,
paths and notes, each in a chart hue, painted to scale; text and notes
scale their type. Artboards carry their names above them.
ZoomControls step out and in through fixed stops, fit on request, and
hold ZoomIndicator, whose press sets 100%. MiniMap draws what lies on
the canvas and the view's box, and centers the view where it is pressed
or dragged. The viewport math, the steps and the map's fit are tested
without gpui.
