CPH Target Runner

English | 简体中文

CPH Target Runner is a CLion plugin for C++ competitive programming. It brings sample management, run results, output comparison, single-file mode, problem import, and Codeforces submission into the right-side CPH tool window, making the CLion local debugging workflow close to VS Code CPH.

Features

• Save independent samples for the current CMake target or a single .cpp file.
• Manage multiple cases with enable/disable, run-one, and run-all workflows.
• Compare stdout against expected output and highlight WA differences.
• Provide pure single-file mode for daily contest practice without maintaining many CMake targets.
• Configure working directory, time limit, C++ standard, compiler options, GCC bits precompiled header, and global shortcuts.
• Receive problems and samples from Codeforces, AtCoder, Luogu, Kattis, and other platforms through Competitive Companion.
• Submit the current .cpp file to the Codeforces problem open in the browser when used with the CPH Target Runner browser extension.

Quick Start

1. Open the right-side CPH tool window in CLion.
2. Click Start CPH to enable the current project.
3. Fill in input and expected output for a case.
4. Click Run to test the current case, or use the top run button to execute all enabled cases.

After a run, the tool window shows stdout, expected output, and the latest result. When the output differs, CPH highlights the differing lines for quick debugging.

Single-File Mode

If you mainly use CLion for contest problems, pure single-file mode is recommended. After it is enabled, each .cpp file becomes an independent run target, and CPH switches samples with the current editor file without requiring manual CMake target maintenance.

Common options are under Settings / Tools / CPH Target Runner, including working directory, C++ standard, compiler options, output comparison mode, and shortcuts.

Import Problems

CPH includes a Competitive Companion receiver, listening on 127.0.0.1:10043 by default. After installing Competitive Companion, click the browser extension button on a problem page; the plugin creates the source file, creates a single-file run configuration, fills in samples, and opens the file.

See the documentation for path templates, variables, and platform rules.

Submit to Codeforces

After installing the CPH Target Runner browser extension, use the submit button in the tool window to submit the current editor .cpp file to the Codeforces problem currently open in the browser.

The plugin does not store Codeforces accounts, passwords, or cookies. Submission uses the browser's current login session.
