The semgrep-idea-plugin is a simple wrapper tool for the Semgrep tool (see GitHub). This should allow you to work in your code environment as you normally would, and receive semgrep notifications in the IDE.

This is a simple wrapper for the semgrep open source tool. See https://github.com/jtmelton/semgrep-idea-plugin for more details.

• Using IDE built-in plugin system:

  Preferences > Plugins > Marketplace > Search for "semgrep-idea-plugin" > Install Plugin

• Manually:

  Download the latest release and install it manually using Preferences > Plugins > ⚙️ > Install plugin from disk...

• semgrep-wrapper:

  At the moment you need to create a wrapper for the semgrep tool. This is necessary because the IDEA plugin has issues with the python env. Having said that, this may change in the future. The key pieces here are that you should:

  • include the full path to semgrep
  • add the json parameter - we expect to parse the json blob to report findings
  • expect 2 parameters: 1) rules file/directory, and 2) file to analyze

     #!/bin/sh
     
     export PATH="/usr/local/Cellar/semgrep/0.31.1/bin/:$PATH"
     
     if [ "$#" -ne 2 ]; then
         echo "You must enter exactly 2 command line arguments: the rules file/dir first, and the file to analyze second"
     fi
     
     /usr/local/Cellar/semgrep/0.31.1/bin/semgrep --config $1 $2 --json --error
