Plagiarism detection for source code.

CI

Plagiarism detection

Plagiarism is detected using the following steps:

  1. Input preprocessing:
    • Whitespace normalization
    • Letter case normalization
    • Language dependent preprocessing. Currently supported languages:
      • x86 GAS assembly
      • C programming language
  2. Similarity check using string metric algorithm. Currently supported algorithms:

Installation options

Download precompiled binaries

Precompiled binaries are available on Releases page. Currently only x86_64-unknown-linux-gnu targets are supported.

Compiling from source

Prerequisites

Compile and install with Cargo:

cargo build --release
cargo install --path .

Usage

Usage: resava [OPTIONS] <SOURCE> [TARGETS]...

Arguments:
  <SOURCE>
          Source file to check for plagiarism

  [TARGETS]...
          Targets to compare against the source file. If a target is a directory, it is searched recursively

          [default: ./]

Options:
  -s, --similarity <SIMILARITY>
          Only show files with specified similarity percentage

          [default: 80]

  -p, --preprocessor <PREPROCESSOR>
          File preprocessor to use

          [default: asm]

          Possible values:
          - asm:  x86 GAS assembly
          - c:    C programming language
          - text: Basic text preprocessing
          - none: Disable preprocessing

  -h, --help
          Print help information (use `-h` for a summary)

  -V, --version
          Print version information
