From 9280c597b000eed661fd98793e182fdcb640f6cd Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Wed, 12 Aug 2026 16:33:14 -0300 Subject: shaders: -Dprebuilt-shaders, so a gui build needs no Vulkan SDK glslc is the one build input that wants a tool a stock machine does not have, and it is also the input that changes least often: eight GLSL files that have outlived several rewrites of everything around them. Asking every machine that wants to run the SDL shell for shaderc is the wrong trade. The SPIR-V is now COMMITTED, under shaders/prebuilt/, and -Dprebuilt-shaders embeds that copy instead of shelling out. The default stays the honest one -- compile the shaders that are actually in the tree -- because the flag trades a dependency for a freshness problem: with it on, the .glsl sources are not build inputs at all, so editing one changes nothing. `zig build shaders` is the other half, and it is deliberately independent of -Dplatform: it recompiles every shader and writes the result back into the tracked directory, so whoever changes a shader refreshes the cache on a machine that has the compiler and commits the diff. `jj diff shaders/prebuilt` after it is the freshness check -- empty means the cache was already current. The shader list is also spelled once now (gui_shaders): the eight embeds, the eight glslc runs and the refresh step all read it, so adding a shader is a name there plus the @embedFile in gui.zig, not three edits in two places. Verified: -Dplatform=gui -Dprebuilt-shaders builds with glslc absent from PATH, and image-harness passes on that binary -- real SDL GPU pipelines built from the committed SPIR-V, 512 source pixels read back. The default gui build still runs the eight glslc steps; tty runs none. The committed bytes are identical to a fresh glslc run, and `zig build shaders` is idempotent. --- src/fonts.zig | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'src/fonts.zig') diff --git a/src/fonts.zig b/src/fonts.zig index e4744daf..1e82956e 100644 --- a/src/fonts.zig +++ b/src/fonts.zig @@ -70,6 +70,17 @@ pub const Font = struct { name: []const u8, path: []const u8 }; pub var want_buf: [4096]u8 = undefined; pub var want: ?[]const u8 = null; +/// ...and the same request as a NAME, for the Debug overlay to show.
