feat: no force | WARNING: Vibe coded

[GalloDaSballo]

Executive Summary

We use --foundry-compile-all at all times
We want to use differential compilation (recompile only what's necessary)

Test

Change medusa.json[compilation] to:

  "compilation": {
    "platform": "crytic-compile",
    "platformConfig": {
      "target": ".",
      "solcVersion": "",
      "exportDirectory": "",
      "args": [
        "--skip-clean",
        "--foundry-no-force"
      ]
    }
  },

It seems to work as intended and is faster, I have to test it on a bigger codebase.

I also don't believe you should use this push, but likely this will help get it done fairly easily.

NOTE: For some reason (maybe tied to slither), you need to compile all the first time or medusa will crash.

Incremental Compilation Patch for CryticCompile + Medusa

Problem

CryticCompile calls forge clean (deletes out/ folder) and uses --force flag on every compilation, causing full rebuilds even when only minor changes are made. This is slow for iterative fuzzing workflows.

Root Causes

1. forge clean removes both out/ (artifacts) and cache/ directories
2. --force flag tells Forge to ignore its cache and recompile everything
3. Default behavior skips test files (--skip */test/**), so test changes aren't detected
4. Forge's incremental compilation creates multiple build-info/*.json files, causing CryticCompile to generate multiple compilation units instead of single combined_solc.json that Medusa expects

Solution

Added --foundry-no-force flag that:

1. Skips forge clean (preserves out/ and cache/)
2. Removes --force flag (enables Forge's incremental compilation)
3. Forces compilation of ALL files including tests (ensures test changes detected)
4. Cleans only out/build-info/ before compilation (prevents multiple compilation units)

Files Changed

• crytic_compile/cryticparser/defaults.py - Added flag default
• crytic_compile/cryticparser/cryticparser.py - Added CLI argument
• crytic_compile/platform/foundry.py - Core implementation

Usage

// medusa.json
{
  "compilation": {
    "platformConfig": {
      "args": ["--skip-clean", "--foundry-no-force"]
    }
  }
}

Result

• Forge recompiles only changed files (11/45 files on subsequent runs)
• Properly detects changes in both source and test files
• Generates single combined_solc.json as expected by Medusa
• Maintains full compatibility with existing workflows (flags are opt-in)
