eftec/bladeone

• Fixed a bug in @foreach and $loop->last. Now it returns the correct value.

• if the view file is not found then it shows the full path.

• updated BladeOneCache.php

• fix in method parseArgs() when it returns a single array

• @splitforeach fixed. Now, it works as base zero.

2018-06-11 2.3.2 Fixed bladeonehtml to allows readonly value.

2018-05-06 2.3.1 Fixed a problem with @verbatim. Add the method runString for evaluating a function

2018-04-13 2.3 The end result clean spaces. PHPDoc cleaned (checked with PHPStorm 2018.1). Fixed some typos (sorry about that).

5.0.0 (2026-03)

Full list of changes applied to this working copy (baseline: upstream 4.19.1).
All bug fixes were experimentally verified before and after the change, and the full test suite
(84 tests / 189 assertions) passes on every step.

Breaking changes

• PHP >= 8.1 is now required (was >= 7.4). Enforced in composer.json.
• Removed ext-json from composer.json requirements (JSON is a core extension since PHP 8.0).
• Version constant bumped 4.19.1 → 5.0.0 (class VERSION + docblock @version).
• Typed signatures on the developer-facing API: code passing wrong types to typed methods now fails
  with TypeError instead of being silently coerced/misbehaving.

Bug fixes

• getInstance() no longer fatals on first call — $instance was a non-nullable typed static
  property without default, so self::$instance === null threw
  "Typed static property … must not be accessed before initialization".
  Now public static ?BladeOne $instance = null;.
• @prepend directive fixed (was doubly broken):
  • startPrepend() used array_unshift($this->pushStack[], $section) (passing a non-variable →
    TypeError: Argument #1 must be of type array, null given). Now
    array_unshift($this->pushStack, $section) — correct LIFO pairing with stopPrepend()'s
    array_shift (nested @prepend now works).
  • compilePrepend() generated $this->startPush(...) (copy-paste bug). Now generates
    $this->startPrepend(...).
• ipClient() regex fixed — pattern was /^(d{1,3}).(d{1,3}).(d{1,3}).(d{1,3})$/ (literal d,
  unescaped dots), so HTTP_X_FORWARDED_FOR was never validated/returned. Now
  /^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$/.
• extract() collisions fixed — evaluateText() and evaluatePath() called
  extract($variables) without EXTR_SKIP; a view variable named content silently replaced the
  compiled code and compiledFile broke the include. Both now use extract($variables, EXTR_SKIP)
  (like runString() already did).
• compileForeach() validates its expression — a malformed @foreach($x) (no as) emitted
  PHP 8 warnings (Undefined array key) and silently generated broken code
  ($__currentLoopData = ;). Now it throws a clear RuntimeException via showError().
• Dead code removed — pointless static::last($this->componentStack); call in endSlot().
• Nullable properties now have explicit = null defaults — $currentUser, $currentRole,
  $baseDomain, $canonicalUrl, $currentUrl (prevents "uninitialized typed property" errors
  when read before being set, e.g. getCurrentUser() without setAuth()).
• isAbsolutePath() — added length guard for one-character paths on Windows (avoids
  Undefined offset warning reading $path[1]).

Performance optimizations (measured, php -n, min of 5 runs)

• Path memoization — getTemplateFile()/getCompiledFile() are called several times per render
  (compile, isExpired, evaluatePath), each doing an is_file() loop + hash. Results are now
  cached per view name in $templateFileCache/$compiledFileCache:
  • Only successful template lookups are cached (a template created later is still found).
  • Invalidation: setPath() and setFileExtension() clear both caches via clearPathCaches();
    setCompiledExtension() and setCompileTypeFileName() clear the compiled cache.
  • Measured: run() with cached compiles ≈ 8-9 % faster (300 renders: ~24.5 ms vs ~26.8 ms).
• getEchoMethods() cached — was rebuilt + uksorted with a closure per HTML token; now
  cached in $echoMethodsCache and invalidated in setContentTags() (rawTags have no setter).
• Native string functions — mb_strpos shims and function_exists('mb_strpos') checks removed
  from startsWith()/contains() in favor of native str_starts_with()/str_contains().
  Together with the rest of the PHP 8 modernization: compilation ≈ 23 % faster
  (compileString ×30: ~16.4 ms vs ~21.5 ms).
• Constructor — iterates class_uses($this) instead of scanning every trait in the process
  (get_declared_traits()), same trait-"constructor" convention.
• $optimize whitespace stripping — two preg_replace() passes merged into one:
  /^(?: {2,}|\t{2,})/m.
• missingTranslation() — filesize+fopen+fwrite+fclose replaced by a single
  file_put_contents(..., FILE_APPEND) (with the 100 KB rewrite rule preserved).
• Negative result (documented, do not retry): caching method_exists() with a
  get_class_methods()-based per-class cache made compilation ~5 % slower (native
  method_exists() is already an O(1) C-level lookup; the strtolower normalization needed to keep
  case-insensitivity — required for @endpushonce → compileEndpushOnce — costs more than it
  saves). Reverted; the attempt is documented in AI_GUIDE.md §9.

PHP 8.1+ modernization

• Native str_contains() / str_starts_with() / str_ends_with() replaced boolean strpos()
  checks in ~18 places: wrapPHP, compileString, postRun, getTemplateFile,
  yieldPushContent, wildCardComparison, compileStatements, fixNamespaceClass, renderEach,
  setBaseUrl, getCurrentUrl(Calculated), parseArgs, …
  (wildCardComparison also uses str_ends_with() and negative string offsets).
• match expressions: colorLog(), compileComments(), compileViewName().
• First-class callable syntax (8.1): self::convertArgCallBack(...) in convertArg().
• Arrow functions: the three echo compilers (compileRawEchos, compileRegularEchos,
  compileEscapedEchos) and restoreVerbatimBlocks() callbacks.
• Negative string offsets: $text[-1] in isQuoted(), $textWithWildcard[-1].
• Removed unnecessary @ suppressions: @explode('?', $link)[0] → plain explode()[0] (always
  defined); @parse_url($this->baseUrl)['host'] → safe (\parse_url(...) ?: [])['host'] ?? null.
• Removed the array_key_last() polyfill at the bottom of BladeOne.php (native since 7.3).
• ext-mbstring is no longer used by the engine itself (kept in suggest for consumers).

Typed signatures (developer-facing API, ~40 methods)

• __construct(), getInstance(): string|array|null $templatePath, ?string $compiledPath, int $mode, int $commentMode.
• run(?string $view, array $variables), runString(string $string, array $data),
  compileString(string $value), compile(?string $templateName, bool $forced).
• getTemplateFile(?string), getCompiledFile(?string), getFile(string), isExpired(?string),
  evaluatePath(string, array), evaluateText(string, array),
  runInternal(string, array, bool, bool), evalComposer(string).
• setPath(), setMode(int), setIsCompiled(bool), setOptimize(bool),
  setFileExtension(string), setCompiledExtension(string), setPhpTag(string).
• directive(string, callable), directiveRT(string, callable),
  registerIfStatement(string, callable), check(string, ...).
• showError(string, string, bool, bool), setAuth(?string, ?string, ?array) (nullable: tests
  legitimately pass null for "no user"), share()/with(string|array, mixed),
  composer(string|array|null, callable|string|object|null).
• getCsrfToken(bool, string), csrfIsValid(bool, string), regenerateToken(string).
• addInclude(string, ?string), addAssetDict()/addAssetDictCDN(string|array, string),
  relative(string), dump(mixed, bool), convertArg(array|string).
• wrapPHP(?string, string, bool), stripParentheses(?string), isQuoted(?string),
  isVariablePHP(?string), addInsideQuote(string, string),
  parseArgs(?string, string, string, bool).
• e(mixed), enq(mixed); getCurrentUser()/getCurrentRole(): ?string + nullable setters;
  setCurrentPermission(?array); setAliasClasses(array), addAliasClasses(string, string).
• wildCardComparison(string, ?string), injectClass(string, ?string), getArgs(?string).
• Deliberately left untyped: methods invoked from compiled templates with user expressions
  (runChild, addLoop, startSection, startPush, _e, _ef, _n, format,
  includeWhen, includeFirst, renderEach, splitForeach, …) so bad template input keeps
  producing the library's friendly errors instead of fatal TypeErrors
  (e.g. @foreach($undefinedVar as $x)).

Tooling / tests

• PHPUnit upgraded ^8.5 → ^10.5 (installed 10.5.65) via
  composer update phpunit/phpunit --with-all-dependencies.
• phpunit.xml migrated to the PHPUnit 10 schema (--migrate-configuration):
  <filter><whitelist> → <source><include>, cacheDirectory=".phpunit.cache", removed
  attributes dropped in 10 (verbose, convert*ToExceptions, …).
• No test code changes were required for PHPUnit 10 — the suite passes as-is.
• .gitignore: added .phpunit.cache/.
• Removed stale artifacts: phpunit.xml.bak, .phpunit.result.cache.
• README.md: PHP badges updated to php->=8.1 and php-8.x.

Documentation

• AI_GUIDE.md (new) — AI-oriented engineering guide: repository map, the two-phase
  compile/runtime mental model, full render pipeline, directive resolution order, state-machine
  fields, modes, file resolution, extension points, error-handling conventions, fixed issues,
  performance notes (incl. the negative result) and testing conventions.
• AI_GUIDE.md updated for 5.0.0: PHP >= 8.1 requirements, PHPUnit 10.5, and a
  "PHP 8.1+ modernization notes" section (incl. the typing strategy).
• This changelog (CHANGELOG.md).

Validation summary

• php -l clean on lib/BladeOne.php.
• PHPUnit: 84 tests / 189 assertions OK (run on every change batch).
• 13-point smoke script: getInstance() first call, nested @prepend, ipClient() valid/invalid,
  startsWith/contains/wildCardComparison, friendly run() error, nullable defaults,
  setAuth(null), VERSION, commentMode behavior — all OK.
• Benchmarks (php -n, min of 5): compileString ×30 ≈ 16.4 ms (was ~21.5 ms),
  cached run() ×300 ≈ 24-27 ms (was ~26.8 ms).

Pull #203

• Added @assetCdn() that works like @asset()
• Addet setCDNUrl()

• Compatibility with PHP 8.4 (without warning)

• Fixed a bug when the stack is called before it is used.
