saw the Commodore PET 8296 featured in a series yesterday and fell in love with the chassis design immediately. it's so old and yet looks so futuristic!

i'm currently developing a visual language for a datalog dialect, and this is what i got. the idea here is that diagonal blocks are relations and their ports. variables are bidi edges. we're looking at multiple lower tris of adjacency matrices. click raster boxes to add/remove edge. autolayouting.

wrote a WHY.md for Tukan.

bit rough around the edges, but it gets the point across i think.

does this make sense?
ImGuiID dock_center = 0; ImGuiID dock_right_up = 0; ImGuiID dock_right_down = 0; bool first_time = true; void frame() { auto dsid = ImGui::DockSpaceOverViewport(); if (first_time) { first_time = false; //ImGui::DockBuilderRemoveNode(dsid); ImGui::DockBuilderAddNode(dsid, ImGuiDockNodeFlags_DockSpace); ImGui::DockBuilderSetNodeSize(dsid, ImGui::GetMainViewport()->Size); ImGuiID dock_right; ImGui::DockBuilderSplitNode(dsid, ImGuiDir_Left, 0.618f, &dock_center, &dock_right); ImGui::DockBuilderSplitNode(dock_right, ImGuiDir_Up, 0.5f, &dock_right_up, &dock_right_down); ImGui::DockBuilderFinish(dsid); } if (ImGui::BeginMainMenuBar()) { if (ImGui::BeginMenu("File")) { if (ImGui::MenuItem("Exit")) { SDL_Event ev; ev.type = SDL_EVENT_QUIT; SDL_PushEvent(&ev); } ImGui::EndMenu(); } ImGui::EndMainMenuBar(); } editor_window(); inspect_window(); misc_window(); runtime_window(); }

yep that did it. nice. AddLine() is probably not the right function to draw circle pieces though

i tried doing this but neither does it prevent the left click from firing, nor does it trigger the right-click (e.g. to activate a context menu). tbh i have no idea what i'm doing

writing yet another dsl for C++ using libsxpp.

this one is called dldsl (datalog dsl)
typedef i32 ID struct node index : ID struct edge a : ID b : ID # transitive closure set struct path a : ID b : ID # facts node 1 node 2 node 3 node 4 node 5 node 6 edge 0 1 edge 0 2 edge 1 3 edge 3 4 edge 2 4 edge 4 5 edge 4 6 # rules for transitive closure if edge x y then path x y if path x y path y z then path x z

the "screaming at cat" meme, but the lady has been mirrored so now it's two identical ladies screaming at each other. left, with a mastodon logo: HYPE! NO POST EDITING! TOXIC QUOTE POSTING! DONGLED TO CENTRAL SERVER! DEBTS TO VENTURE CAPITAL! BLOCKCHAIN CEO! ABLEIST DESIGN! right, with a bluesky logo: NO MOMENTUM! POST REVISIONISM! NO QUOTE POSTING! TERRIBLE CROSS-SERVER UX! AWFUL NAME! LECTURING GERMANS EVERYWHERE! and then there's a third panel with the cat looking in the opposite direction, with a white-on-red X logo: HELLO? WHERE IS EVERYONE?
