gomodvet

gomodvet is a simple prototype. It is an experimental tool that checks for potential modules-related issues.

WIP.

Rules

There are currently 8 rules:

• gomodvet-001: the current module's go.mod file would be updated by 'go build'
• gomodvet-002: a module has multiple major versions in this build
• gomodvet-003: module "foo" was required with potentially incompatible versions: v0.9.0, v1.0.0
• gomodvet-004: using a version excluded by another module: github.com/go-chi/chi@v1.0.1
• gomodvet-005: using a prerelease version: github.com/go-chi/chi@v4.0.0-rc2
• gomodvet-006: using a pseudoversion version: github.com/go-chi/chi@v0.0.0-20151106203253-e413833c12f1
• gomodvet-007: dependencies have available updates
• gomodvet-008: the current module uses 'replace' directives

Most of those are not strictly speaking "problems" in all cases, but most of those are at least notable situations. (For example, a module with multiple major versions in a build might be a conscious choice, or might be because someone is doing import "foo/v3" in one spot and accidentally doing import "foo" in another spot).

Usage

Example invocation that checks all but two rules: gomodvet -upgrades=false -pseudoversion=false

Usage of gomodvet:

  -conflictingrequires
        report if there are requirements for potentially conflicting v0 versions or 
        '+incompatible' versions for different major versions (default true)
  
  -excludedversion
        report if the current build is using a version excluded by a dependency (default true)
  
  -multiplemajor
        report if a module has multiple major versions in use (default true)
  
  -prerelease
        report if the current build is using a prerelease version (exclusive of pseudo-versions,
        which are reported separately) (default true)
  
  -pseudoversion
        report if the current build is using a pseudo-version (default true)
  
  -replace
        report if the main module is using any 'replace' directives (default true)
  
  -upgrades
        report if the current module has available updates for its dependencies (default true)
  
  -v    verbose: show additional information
