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. --- test/snapshots/topbarexec.golden | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) (limited to 'test/snapshots/topbarexec.golden') diff --git a/test/snapshots/topbarexec.golden b/test/snapshots/topbarexec.golden index bed96fbd..8d15d6c4 100644 --- a/test/snapshots/topbarexec.golden +++ b/test/snapshots/topbarexec.golden @@ -21,16 +21,16 @@ | == snap noarg-runs grid=90x20 cursor=14,3 |New Newcol Find Grep Help Tutor Dump NextColor Debug Kill -| /tmp/pardes-snap/topbarexec/cwd New Del /tmp/pardes-s╭────────────────────────────╮ -| ls ls │pardes resizes=1 │ -| zmarkfile.txt zmarkfile.txt│terms 3 cols 2 │ -| │active #0 43x9 │ -| │scroll 0/9 │ -| │pinch 1.0000 │ -| │tscroll 0.0000 │ -| ╰────────────────────────────╯ -| -| +| /tmp/pardes-snap/topbarexec/cwd New Del /tmp/╭────────────────────────────────────╮ +| ls ls │pardes resizes=1 │ +| zmarkfile.txt zmark│theme helix │ +| │font default │ +| │terms 3 cols 2 │ +| │active #0 43x9 │ +| │scroll 0/9 │ +| │pinch 1.0000 │ +| │tscroll 0.0000 │ +| ╰────────────────────────────────────╯ | /tmp/pardes-snap/topbarexec/cwd New Del | ls | zmarkfile.txt -- cgit v1.3
