Loading a graph (vertices & undirected edges) from files then displaying it on screen. Features Netwire/GLFW/VinylGL/netwire-input/STM loading screen. Semi-tutorialized by implementing required behavior across different executables.
See README-verbose.md for things like the semantics, concepts, research, & design behind these examples, advanced usage instructions, gaps in development, & future steps.
Once built, copy the binaries & the etc and graphs folders into a fixed directory.
Run the executables from the shell. Otherwise, external files may not be loaded, so they won't run.
CtrlExample.(l)hs
Demonstrates in Netwire the kind of permanent state change needed in a loading screen. The cursor has a time-varying color when the program starts, but when the user hits the C key, it becomes green. Color responds to pressing the R, G, & B keys before & after, as in the example this is based off of.
ReportingProgressExample.(l)hs
STM example wherein a computation forked off into a different thread reports its completion status to the root computation.
ReportingLoadExample.hs
STM example wherein a file is loaded and its progress reported as it loads chunks. The load is done in its own thread, so the root computation can interact w/ the user while the file is loading.
GraphLoadingScr.hs
This executable loads the graph, then displays it. It uses the completed loading screen.
Before the file is loaded, the program displays a while circle used as a cursor. Once the user hits L, the graph begins loading. While it's loading, the cursor circle oscillates in hue. Each time a chunk of a file loads, the cursor gets darker. Once both files of the graph are loaded, the cursor becomes that graph, displayed in green. For simplicity, only the edges are drawn.
