MilkDrop's compiler accepts HLSL C-style casts ((float)k * 0.2, (float2)x, (int)(a + b)). Our GLSL translator did not, so the stage was dropped as "not compiled". Found while building a CaYaDev preset (#825).

Change

• src/shared/milkdrop-shader.js: cCast() turns a cast into a GLSL constructor. It binds to the term right after the cast, as in HLSL: a name, number or parenthesised group, then calls, .members and [index]. (int) goes through the existing int( → trunc( path. A parenthesised type preceded by an identifier (sizeof(float)) is left alone.
• tests/milkdrop-compile-gaps.test.js: two tests (scalar cast in a loop; vector, group and member-chain casts; function parameters untouched).

Verified

• The test preset that failed (for (int k…) a += (float)k * 0.2;) now compiles in WebGL in the preview harness. Before the change it showed "comp: derlenmedi".
• The 10,347-file corpus has no such casts (grep for (type) with optional spaces finds none), so no existing preset's shader changes.
• npm test: 3511/3511. The test count is updated in README, README.tr and ROADMAP.

CaYaDraft — pull request

Summary
This pull request adds support for HLSL C-style casts (e.g., (float)k) to the MilkDrop shader translator, which previously caused compilation failures. The cCast() function in milkdrop-shader.js now converts these casts into equivalent GLSL constructors by binding to the term immediately following the cast, while leaving parenthesized types preceded by identifiers unchanged.
