cey is the C* compiler. It transpiles .cy source files to C, then compiles them using gcc or clang.

#ekle <stdgç.b>
#ekle <stdküt.b>

tam ana(boşluk) {
    tam* dizi = (tam*) bellekal(5 * boyut(tam));
    için (tam i = 0; i < 5; i++) {
        dizi[i] = i * 2;
    }
    yazdırf("Merhaba C*\n");
    bırak(dizi);
    döndür 0;
}

cey <input-files> [compiler-args] [cey-options]

cey -Wall -Werror ./example.cy -o ./build/example -- --cc=clang

Only files ending with .cy are compiled by cey. All other files and arguments are passed directly to the C compiler.

Use -- to separate C compiler arguments from cey options, if any.

• --pack: Minify the generated C file (removes whitespace, breaks error messages).
• --cc=gcc or --cc=clang: Choose the backend compiler. Default is gcc.
• --int: Preserve the intermediate files.

Intermediate files are written to /tmp/cey_tmp_*/ and automatically deleted after compilation.

yec is a separate binary used to reverse-transpile C code to C*. It only performs transpilation, not compilation.

yec <source_file> <destination_file>

To fully rebuild the compiler from its own source using the current toolchain, run:

make bootstrap

This will:

• Use amalgamator to generate an amalgamated C source file from src/cey.c and save it as build/amalgamation.c.
• Reverse-transpile the amalgamated C source into C* (examples/cey.cy) using yec.
• Compile cey.cy with the current cey compiler to produce a new cey binary, replacing the existing one in build/cey.
