How do I print Go code with syntax highlighting?

Paste your Go code into Codeprint and select Go as the language. Keywords, types, struct tags, and comments are highlighted. Export via Print or PDF.

Does it support Go generics?

Yes. Go 1.18+ generics syntax including type parameters, constraints, and type sets are highlighted correctly.

Can I print Go test files?

Yes. Go test functions (Test*, Benchmark*, Example*) and testing package usage are highlighted like any other Go code.

How does Go's formatting affect printing?

Go's gofmt-enforced formatting produces consistently indented code that prints very cleanly. The consistent style means printed Go code is always well-structured.

Turn Go code into a PDF worth printing.

Keep Go syntax colors, line numbers, and the layout you choose. Preview every page and export the PDF without uploading your code.

Go Syntax Highlighting

Full support for Go structs, interfaces, goroutines, channels, defer, and struct tags.

PDF Export

Export Go files as PDF with clean formatting that matches Go's emphasis on simplicity.

Customizable Layout

Go's enforced formatting (gofmt) produces consistently readable code. Choose your preferred font size and page layout.

Line Numbers

Line numbers for referencing specific functions and methods during code reviews.

When you’d print Go

Code Reviews

Print Go code for offline review. Go's simple syntax makes printed code very readable for careful analysis.

Systems Documentation

Print Go microservice code for architecture documentation. Include handler functions and data models.

Teaching Go

Create handouts for Go workshops. Go's small language spec makes printed examples effective teaching aids.

Concurrency Analysis

Print goroutine and channel code for offline analysis of concurrent patterns and potential race conditions.

How it works

Step 1

Paste Your Code

Paste your Go code into the editor or type directly. The language is auto-detected from the file extension.

Step 2

Customize Settings

Adjust font size, line numbers, columns, page orientation, and page size to match your needs.

Step 3

Print or Export PDF

Click Print to send to your printer, or PDF to download a formatted document with syntax highlighting preserved.

Why print Go?

Go source is easier to review when its structure survives the move from editor to page. Full support for Go structs, interfaces, goroutines, channels, defer, and struct tags. Codeprint keeps indentation and line breaks intact, then applies a restrained syntax palette so keywords, strings, comments, and identifiers remain distinguishable in print.

A paper review creates a different reading rhythm from an IDE. You can see more of the file at once, mark a questionable branch, compare related expressions, and refer back to a precise line without opening the same toolchain. Line numbers for referencing specific functions and methods during code reviews.

Export Go files as PDF with clean formatting that matches Go's emphasis on simplicity. Page size, orientation, columns, and type size remain under your control, which matters when the source contains long expressions or dense blocks. It is a practical fit for code reviews, systems documentation, and technical documentation. Your source stays in your browser throughout the process.
