How do I print Ruby code with syntax highlighting?

Paste your Ruby code into Codeprint and select Ruby as the language. Keywords, symbols, blocks, and string interpolation are highlighted. Export via Print or PDF.

Does it support Ruby on Rails code?

Yes. Rails code is standard Ruby and is fully highlighted. ActiveRecord queries, routing DSL, and controller actions are all colorized correctly.

Can I print ERB templates?

ERB templates mix Ruby and HTML. Select Ruby as the language for the best Ruby highlighting. The HTML portions will be treated as part of the Ruby output.

How does it handle Ruby heredocs?

Ruby heredoc strings (<<~HEREDOC) are highlighted as string literals with proper delimiter recognition.

When you’d print Ruby

Code Reviews

Print Ruby code for careful offline review. Ruby's expressiveness benefits from focused reading.

Rails Development

Print Rails models, controllers, and services for architecture discussions and team reviews.

Teaching Ruby

Create handouts for Ruby workshops. Ruby's readable syntax makes printed examples effective.

Script Documentation

How it works

Step 1

Paste Your Code

Paste your Ruby 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 Ruby?

Ruby source is easier to review when its structure survives the move from editor to page. Full support for Ruby blocks, symbols, heredocs, regex, and metaprogramming patterns. 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 methods and blocks during pair programming reviews.

Export Ruby files as PDF with elegant formatting that matches Ruby's expressive syntax. 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, rails development, and technical documentation. Your source stays in your browser throughout the process.
