Summary

Request interrupted by user for tool use

Now I need to add assertSlice to covered_test.go (since it's used by both covered_test.go and project_test.go in the root package, and extract_test.go which defined it is moving away). And delete the old files from root.

Now delete the old files from root:

The diagnostic is stale from before the delete. Let me build and test:

All 64 tests pass across all packages. Build, vet, and tests all clean.

Everything is done. Here's a summary of what changed:

New files:

internal/core/core.go -- ReuseInfo, SourceType, PrecedenceType and all their constants/methods
extract/extract.go + extract/extract_test.go -- SPDX header extraction (was root extract.go)
dep5/dep5.go + dep5/dep5_test.go -- dep5 parser (was root dep5.go)
toml/toml.go + toml/toml_test.go -- REUSE.toml parser (was root toml.go)
toml/glob.go + toml/glob_test.go -- glob matching (was root glob.go, moved here since only toml uses it)

Modified files:

reuse.go -- rewritten to type aliases and constant re-exports from internal/core
project.go -- imports extract, dep5, toml subpackages; Project struct fields now use subpackage types
covered_test.go -- added assertSlice helper (previously lived in extract_test.go)

Deleted files:

extract.go, extract_test.go, dep5.go, dep5_test.go, toml.go, toml_test.go, glob.go, glob_test.go from root

Unchanged files:

covered.go, project_test.go

commit this with "Hello world"

Committed as 15fc8b5 with message "Hello world".

empty repo here: https://github.com/git-pkgs/reuse

Ready to push to git@github.com:git-pkgs/reuse.git. This will push the main branch to the remote. Want me to go ahead?

yes

Pushed to https://github.com/git-pkgs/reuse.

failing ci

Lint failure: toml/glob.go:31 wants a tagged switch instead of if/else chain on next.

Tests pass. Want me to commit and push this fix?

yes

Pushed as 1fb6b84.

check if ci passes now

Still running. Let me wait a bit.

CI passes.

now let's look at the dependabot PRs

No open PRs. Dependabot may have auto-merged or the updates were applied directly. Let me check if there are recently closed/merged ones.

No PRs at all. The Dependabot runs we saw earlier were just the initial config checks, not actual PRs. Nothing to review.

can this tool be used in a similar way to scancode license checker?

They solve related problems but work differently.

ScanCode scans file contents and matches them against a database of known license texts. It can identify a license even when there are no SPDX tags, by recognizing patterns in license headers, notices, and full license texts. It's detection-based.

This library reads structured SPDX metadata that authors have explicitly added following the REUSE spec: SPDX-License-Identifier headers, .license sidecars, REUSE.toml annotations, and dep5 files. It doesn't try to identify licenses from arbitrary text. If a file has no SPDX tags and isn't covered by a REUSE.toml or dep5 entry, this library just reports it as having no licensing info.

So ScanCode works on projects that haven't adopted any particular standard. This library works on projects that follow the REUSE specification. In a REUSE-compliant project, every covered file has explicit SPDX metadata, and this library is all you need. For projects without that discipline, you'd want something like ScanCode.

They could complement each other: use ScanCode to audit a project that lacks structured metadata, then use the results to add REUSE-compliant tags, then use this library going forward.

Implement the following plan:

Reorganize reuse into subpackages by concern

Currently all code lives in one flat reuse package. Move parsers into public subpackages, matching the internal/core + type alias pattern used by manifests and registries.

Problem: import cycles

Root package (project.go) imports subpackages. Subpackages need ReuseInfo, SourceType, PrecedenceType from root. That's a cycle.

Fix: move shared types to internal/core. Root re-exports them as type aliases (type ReuseInfo = core.ReuseInfo). Subpackages import internal/core directly. No cycles.

Target structure

reuse/
  reuse.go               type aliases from internal/core, package docs
  project.go             Project, OpenProject, ReuseInfoOf, AllReuseInfo
  project_test.go
  covered.go             IsCoveredFile, CoveredFiles, IsIgnoredDir, IsIgnoredFile
  covered_test.go
  internal/
    core/
      core.go            ReuseInfo, SourceType, PrecedenceType (actual definitions + methods)
  extract/
    extract.go           ExtractReuseInfo, ExtractFromFile, FilterIgnoreBlocks
    extract_test.go
  dep5/
    dep5.go              Dep5, ParseDep5, ParseDep5File, ReuseInfoOf
    dep5_test.go
  toml/
    toml.go              ReuseTOML, Annotation, ParseReuseTOML, ParseReuseTOMLFile, ReuseInfoOf
    toml_test.go
    glob.go              GlobMatch (only used by toml, stays here)
    glob_test.go

What moves where

reuse.go types/constants/methods -> internal/core/core.go
reuse.go becomes type aliases + package doc
extract.go + test -> extract/ subpackage, package extract, imports internal/core
dep5.go + test -> dep5/ subpackage, package dep5, imports internal/core
toml.go + test -> toml/ subpackage, package toml, imports internal/core and uses alias for BurntSushi/toml (btoml)
glob.go + test -> toml/ subpackage (glob is only used by toml matching)
covered.go + test -> stays in root (no deps on subpackages, no cycle risk)
project.go + test -> stays in root, imports extract, dep5, toml subpackages

Import paths after reorganization

Consumer usage:

Changes to each file

internal/core/core.go (new)

All types, constants, methods from current reuse.go
package core

reuse.go (rewrite)

Package doc stays
Type aliases: type ReuseInfo = core.ReuseInfo, type SourceType = core.SourceType, etc.
Constant re-exports: const (FileHeader = core.FileHeader; ...)

extract/extract.go

Change package reuse -> package extract
Import github.com/git-pkgs/reuse/internal/core
Replace ReuseInfo with core.ReuseInfo, FileHeader with core.FileHeader

dep5/dep5.go

Change package reuse -> package dep5
Import github.com/git-pkgs/reuse/internal/core
Same type replacements

toml/toml.go

Change package reuse -> package toml
Import btoml "github.com/BurntSushi/toml" (alias to avoid name conflict with package name)
Import github.com/git-pkgs/reuse/internal/core
Same type replacements

toml/glob.go (moved from root)

Change package reuse -> package toml
No other changes needed

project.go

Add imports for extract, dep5, toml subpackages
Replace direct function calls: ExtractFromFile -> extract.ExtractFromFile, etc.
Replace ParseReuseTOMLFile -> toml.ParseReuseTOMLFile
Replace ParseDep5File -> dep5.ParseDep5File
Types stay as ReuseInfo etc. since root re-exports them

covered.go

No changes (no deps on moved code, only uses stdlib)

Tests

Each test file moves with its source, changes package name
assertSlice helper is duplicated into each test package (or made a shared test helper)
mkfile helper stays in root test (project_test.go, covered_test.go)
extract_test.go and dep5_test.go each get their own assertSlice

Verification

go build ./...
go test -v -race ./...
go vet ./...
Confirm 64 tests still pass across all packages

Now let me read all the test files.

I have a clear picture of the full codebase. Let me create the task list and then implement everything. The key challenge is that Go won't compile with duplicate symbols, so I need to swap old files for new ones atomically.

I'll start by reading the current files to understand the exact code before making changes.

Good, the diagnostic is just from the file being created in stages. Now the toml test files:

Now update project.go to import the subpackages:
