Add a language/framework profile

Creates a new auto-applied tuning profile that seeds framework-aware excludes and block-size tuning whenever phpdup analyze --profile auto (or --profile <name>) detects the matching project layout.

Critical

• The profile JSON validator rejects unknown keys. Allowed top-level keys: _description, exclude, kinds, min_block_size, max_block_size, normalization_mode, similarity_threshold, tree_threshold, min_cluster_impact, max_df, ngram_size, sort. Anything else fails --validate-config and breaks vendor/bin/phpunit.
• kinds values must come from BlockExtractor::ALL_KINDS: method, function, closure, if, for, foreach, while, do, try, switch, match. No others.
• Profiles are folded in as low-priority overrides — explicit CLI flags and --config always win (see src/Cli/Command.php execute method ~line 200). Do not assume your profile values are final; pick conservative defaults.
• Detection order in src/Cli/ProjectProfileDetector.php is specificity-first: framework-specific marker files come before the generic composer.json fallback. Insert your new check above the composer.json branch, in a position consistent with how distinctive its markers are.
• Detection markers must be files (is_file() via any()), not directories. Pick markers that are nearly always present and rarely fake — entry scripts, version stamps, or required core classes.
• Three excludes are mandatory in every profile: vendor/**, node_modules/**, **/.phpdup-cache/**. The cache exclude prevents phpdup's own cache from being scanned in subsequent runs.
• You must update three locations atomically: the profile JSON under profiles/, KNOWN_PROFILES in src/Cli/ProjectProfileDetector.php, and testRegistryLoadsBundledProfiles in the test file. Forgetting any one breaks tests or --profile <name> lookup.

Instructions

Step 1 — Identify marker files

Decide 1-3 paths whose presence uniquely identifies a <framework> project. Look at the existing markers in src/Cli/ProjectProfileDetector.php for the bar:

• Laravel: the artisan entry script and core kernel/config files
• Symfony: the console entry script and Kernel class plus services config
• Drupal: the core Drupal lib (under core/ or web/core/)
• WordPress: the wp-config files and the wp-includes version stamp

Verify before proceeding: each marker must be a file path relative to the project root, must be present in a default install, and must not collide with markers in another already-supported profile.

Step 2 — Write the profile JSON

Create the new profile file under profiles/ (lowercase, no spaces). Use this exact shape, mirroring profiles/laravel.json:

{
    "_description": "Framework — auto-applied when its marker files are detected. One sentence on what this profile excludes and why.",
    "exclude": [
        "vendor/**",
        "node_modules/**",
        "**/.phpdup-cache/**"
    ],
    "kinds": ["method", "function", "closure", "if", "for", "foreach", "while", "do", "try", "switch", "match"],
    "min_block_size": 6,
    "min_cluster_impact": 18
}

Tune from these reference points:

• min_block_size: 6 if the framework's app code has tight handlers (Laravel/Symfony/WordPress); 8 if it generates lots of boilerplate hook stubs (Drupal).
• min_cluster_impact: 15 (WordPress) – 25 (Drupal). Higher for boilerplate-heavy ecosystems.
• kinds: include closure only if the framework's idioms use closures heavily (routes, container bindings). WordPress/Drupal omit it.
• exclude: add the framework's generated/cache/build dirs (e.g., Laravel bootstrap/cache/**, Symfony var/**, Drupal core/**, WordPress wp-admin/**, wp-includes/**). Also exclude vendored bundled plugins/themes that ship with the CMS.

4-space indent. Trailing newline. Use double quotes (JSON).

Verify before proceeding:

php -r 'json_decode(file_get_contents("profiles/codeigniter.json"), false, 512, JSON_THROW_ON_ERROR); echo "ok\n";'

should print ok.

Step 3 — Register the profile in src/Cli/ProjectProfileDetector.php

1. Add the profile name to KNOWN_PROFILES (line 18). Keep 'generic' last:

   private const KNOWN_PROFILES = ['laravel', 'symfony', 'drupal', 'wordpress', 'codeigniter', 'generic'];
   

2. Add a new branch inside the detectIn() method before the composer.json fallback. Use the $this->any($root, [...]) helper with the markers from Step 1:

   if ($this->any($root, ['marker1', 'marker2'])) {
       return 'codeigniter';
   }
   

   Place it next to ecosystem peers (e.g., other CMSes near WordPress/Drupal; other application frameworks near Laravel/Symfony) so the file remains readable.

Do not modify the detect() loop, any() helper, or knownProfiles() getter.

Verify before proceeding: vendor/bin/phpstan analyse src/Cli/ProjectProfileDetector.php exits 0.

Step 4 — Add a detection test

Edit tests/Unit/Cli/ProjectProfileDetectorTest.php. Append a new test method following the existing naming + body pattern (testLaravelMarkerDetectsLaravel):

public function testCodeIgniterMarkerDetectsCodeIgniter(): void
{
    $root = $this->mkproject(['spark' => '#!/usr/bin/env php']);
    $this->assertSame('codeigniter', (new ProjectProfileDetector())->detect([$root]));
}

File contents in mkproject() only need to make is_file() true — '<?php // marker' or '#!/usr/bin/env php' is enough. Do not write real framework code.

Then extend testRegistryLoadsBundledProfiles (around line 59) to assert your new profile is bundled:

$this->assertContains('codeigniter', $available);

Add it next to the existing assertContains('wordpress', $available); line in alphabetical / grouping consistency with the existing assertions.

Do not change testComposerJsonAloneIsGeneric, testEmptyDirIsGeneric, or testRegistryRejectsUnknownProfile.

Step 5 — Verify the full chain

Run in order. Stop and fix at the first failure:

vendor/bin/phpunit --testsuite Unit --filter ProjectProfileDetectorTest
vendor/bin/phpstan analyse
vendor/bin/psalm
bin/phpdup analyze --config profiles/codeigniter.json --validate-config

All must pass. The --validate-config step is the canonical check that your JSON keys are valid (the loader strips _description automatically per ProfileRegistry::load()).

Then smoke-test detection on a real project root if available:

bin/phpdup analyze --profile auto <path-to-test-project>

The first line of output should print phpdup profile auto-detect: codeigniter.

Examples

User says: "Add a profile for CodeIgniter 4."

Actions taken:

1. Pick markers: the spark CLI entry, the App config under app/Config/, and the framework's CodeIgniter class under system/.
2. Create profiles/codeigniter.json:

   {
       "_description": "CodeIgniter 4 — auto-applied when its marker files are detected. Excludes the framework's system/ tree and writable/ runtime dirs so user app/ + Modules/ code dominates the report.",
       "exclude": [
           "vendor/**",
           "system/**",
           "writable/**",
           "public/**",
           "node_modules/**",
           "**/.phpdup-cache/**"
       ],
       "kinds": ["method", "function", "closure", "if", "for", "foreach", "while", "do", "try", "switch", "match"],
       "min_block_size": 6,
       "min_cluster_impact": 18
   }
   

3. In src/Cli/ProjectProfileDetector.php:
   • KNOWN_PROFILES → ['laravel', 'symfony', 'drupal', 'wordpress', 'codeigniter', 'generic']
   • After the Symfony if branch, insert:

     if ($this->any($root, ['spark', 'app/Config/App.php', 'system/CodeIgniter.php'])) {
         return 'codeigniter';
     }
     

4. In tests/Unit/Cli/ProjectProfileDetectorTest.php, add:

   public function testCodeIgniterMarkerDetectsCodeIgniter(): void
   {
       $root = $this->mkproject(['spark' => '#!/usr/bin/env php']);
       $this->assertSame('codeigniter', (new ProjectProfileDetector())->detect([$root]));
   }
   

   And in testRegistryLoadsBundledProfiles, add $this->assertContains('codeigniter', $available);.
5. Run vendor/bin/phpunit --testsuite Unit --filter ProjectProfileDetectorTest → green.
6. Run vendor/bin/phpstan analyse and vendor/bin/psalm → no new errors.

Result: bin/phpdup analyze --profile auto path/to/ci-app prints phpdup profile auto-detect: codeigniter and seeds the listed excludes/tuning before any CLI overrides are applied.

Common Issues

RuntimeException: Profile 'codeigniter' is not valid JSON The file is empty, has a BOM, or has a trailing comma. Run php -r 'var_dump(json_decode(file_get_contents("profiles/codeigniter.json"), true));' — if it prints NULL, JSON is malformed. Re-emit with double quotes and no trailing commas.

phpdup: --validate-config rejects an unknown key You added a key not in the validator's allowlist. Allowed keys are listed in Critical above and enforced by ConfigLoader::validate(). Move arbitrary metadata into _description (it is stripped by ProfileRegistry::load() line 43).

testRegistryLoadsBundledProfiles fails with Failed asserting that ... contains 'codeigniter' You created the profile JSON but didn't update the test's assertContains block. Add the assertion. Check that the filename is exactly the profile name (lowercase, no underscores unless intentional) — ProfileRegistry::listAvailable() strips the .json suffix verbatim.

testRegistryLoadsBundledProfiles passes but --profile codeigniter fails with --profile must be one of ... You forgot to add the name to KNOWN_PROFILES in src/Cli/ProjectProfileDetector.php. The CLI checks $registry->listAvailable() for membership but the constant is what knownProfiles() returns to other callers; keep them in sync.

Auto-detect picks the wrong profile (e.g., a Laravel-on-top-of-WordPress repo resolves to wordpress) Detection order is first-match-wins. Move the more-specific framework's branch above the more generic one. The Laravel branch sits first deliberately. If two frameworks legitimately coexist, document the conflict in the profile's _description and prefer the application-layer framework over the host CMS.

vendor/bin/phpstan analyse reports Constant ... has unknown type Double-check the KNOWN_PROFILES literal stays a list<string> — no trailing commas inside the array on PHP 8.1, no nested arrays, no non-string entries.

Unit test passes locally but Golden suite fails after profile change You edited an existing profile rather than adding a new one. Existing profile values are baked into golden snapshots. If the change is intentional, refresh: UPDATE_SNAPSHOTS=1 vendor/bin/phpunit --testsuite Golden. If not, revert and create a new profile name instead.
