zig translate-c to Read C as Zig
Convert C source into Zig code.
zig translate-c to Read C as Zig is a free Zig Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Zig Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Read C as Zig
Sometimes you want to see C as plain Zig source. The zig translate-c command converts a C file into readable Zig.
zig translate-c input.cIt Prints to stdout
By default translate-c writes the generated Zig to stdout. Redirect it to a file when you want to keep and edit the result.
zig translate-c input.c > out.zigSame Engine as @cImport
Under the hood, @cImport uses the very same translator. translate-c just lets you inspect the Zig it would have produced.
Great for Learning
Reading the output shows how a C declaration maps to Zig, which is a fast way to understand the type translations.
Pass Include Paths
If the C uses headers in other folders, give translate-c -I flags so it can find and parse them correctly.
zig translate-c -I include input.cDefine Macros Too
Just like a C compiler, you can pass -D to set macros before translation, shaping which code paths get converted.
zig translate-c -DDEBUG=1 input.cNot Everything Translates
Some C constructs are too tricky and emit an opaque placeholder or a comment. You then write that small piece of Zig by hand.
A One-Time Conversion
translate-c is best as a starting point. You generate Zig once, then maintain it as normal source rather than re-running it forever.
Compare with @cImport
Use @cImport for live, always-fresh bindings during a build; use translate-c when you want a permanent Zig file you can edit.
Output Is Real Zig
The result is ordinary, compilable Zig. You can format it with zig fmt and treat it like any other module in your project.
From C Source to Zig
So translate-c closes the loop: it turns existing C source into Zig you can read, study, and ship as part of your codebase.
Quick Check
Think about where translate-c sends its result by default.
Recap
You learned that zig translate-c converts C source into readable Zig on stdout, using the same engine as @cImport for a one-time conversion. 🎯
