Perl Beautifier: Browser-Based Perl Code Reindenter
Perl Beautifier is a conservative, brace-aware Perl code re-indenter. Paste or drop in Perl code, choose the indentation and available options, then review and copy the result. It changes indentation only, leaving strings, comments, and POD untouched. It is labeled basic because no reliable in-browser full Perl formatter exists.
Perl Beautifier is a browser-based Perl code re-indenter for developers who want clearer indentation without a broad source rewrite. It is conservative and brace-aware, so it focuses on the layout of Perl code rather than changing its contents. The tool is labeled basic because no reliable in-browser full Perl formatter exists.
To use it, paste or drop in Perl input, choose the indentation and available options, and review the result. The re-indenter changes indentation only: strings, comments, and POD are not altered. This limited approach helps keep the original code content intact while making its structure easier to read.
Perl is a programming language, while indentation is a way to present code structure consistently. Re-indenting can make machine-generated files, unfamiliar scripts, and code under review easier to scan. It can also reduce whitespace noise in diffs, so reviewers can focus on meaningful changes. This tool is not a full Perl formatter, so it does not promise broader code transformations.
Perl Beautifier runs entirely in your browser. Your input is processed on your device; nothing is uploaded, stored, or sent to a server. It is free, requires no signup, and works offline once the page has loaded. Developers and DevOps engineers can use it to tidy scripts, prepare snippets for discussion, and review Perl code with a straightforward browser-based workflow.
Step 1: Paste or drop your Perl code into the tool. Use the snippet or file content you want to re-indent.
Step 2: Choose the indentation and any available options. These let you set how the formatted code is indented.
Step 3: Run Perl Beautifier to re-indent the input. The tool is conservative and changes indentation only.
Step 4: Review the output, then copy it for your editor, commit, bug report, or code review.
Use case: Make an unreadable, machine-generated Perl file easier to review before committing it. Re-indenting helps make the code structure clearer.
Use case: Check Perl code you did not write against the indentation style you need to follow. The tool changes indentation without rewriting strings, comments, or POD.
Use case: Reduce whitespace noise in a diff by producing consistently indented output. That can make substantive code changes easier to spot.
Use case: Format a Perl snippet before pasting it into a bug report or code review. A clearer layout can help others follow the code.
Use case: Check whether Perl input parses cleanly and find the exact line where it does not. This can help focus debugging on the problematic part of the input.
Use case: Re-indent a small code sample while working offline after the page has loaded. The tool runs in your browser and does not need a server connection.
Use case: Tidy up a Perl script before sharing it with teammates. Consistent indentation makes the code easier to scan without changing its strings, comments, or POD.
