Remove deprecated type attribute from link and script tags

[koriym]

Summary

Following up on PR #64, this PR removes the remaining deprecated type attributes:

• Remove type="text/css" from <link> tags in fixAttr()
• Remove type="text/javascript" from <script> tags in attr()

In HTML5, type="text/css" for stylesheets and type="text/javascript" for scripts are the defaults and no longer required.

Walkthrough

The changes remove explicit MIME type attributes (type="text/javascript" from script tags and type="text/css" from stylesheet elements) from generated HTML, relying on browser defaults. Corresponding test cases have been updated to reflect the new output.

Changes

Cohort / File(s)	Summary
Script and Stylesheet Helper Updates src/Helper/Scripts.php, src/Helper/Styles.php	Removed automatic type attribute insertion—scripts no longer emit type="text/javascript" and stylesheets no longer emit type="text/css". Attribute handling logic adjusted to conditionally format tags based on presence of other attributes.
Test Case Updates tests/Helper/ScriptsTest.php, tests/Helper/StylesTest.php	Updated expected HTML output strings across all test cases to match the removal of MIME type attributes from generated script and link/style elements, including within conditional IE blocks.

Poem

🐰 A rabbit's refrain:
Type attributes fade away,
Defaults now suffice, hooray!

tests/Helper/StylesTest.php (4)

17-17: LGTM! Test expectation correctly updated.

The expected output now correctly omits the deprecated type="text/css" attribute, aligning with HTML5 standards where this attribute is optional for stylesheets.

---

31-34: LGTM! Consistent removal of deprecated type attributes.

All expected link tag outputs correctly omit the type="text/css" attribute, including within conditional IE comments.

---

50-53: LGTM! Type attribute removal preserves other attributes.

The changes correctly remove the type attribute while preserving the media attribute and indentation functionality.

---

75-78: LGTM! Internal style blocks correctly updated.

Expected output for inline <style> tags correctly omits the type="text/css" attribute, consistent with the changes to <link> tags.

tests/Helper/ScriptsTest.php (3)

17-17: LGTM! Script tag expectation correctly updated.

The expected output correctly omits the deprecated type="text/javascript" attribute, which is the default in HTML5.

---

34-38: LGTM! Custom attributes preserved correctly.

The expected outputs correctly omit the type attribute while preserving custom attributes like foo, bar, and bing. Both regular and conditional script tags are handled consistently.

---

60-63: LGTM! Internal script blocks correctly updated.

Expected output for inline <script> tags correctly omits the type attribute, consistent with external script tag changes.

src/Helper/Scripts.php (3)

112-112: LGTM! Consistent with addInternal implementation.

The conditional internal script generation follows the same clean pattern, correctly omitting attributes when none are provided. This maintains consistency with the addInternal() method.

---

184-190: LGTM! Core change removes deprecated type attribute.

The attr() method now only adds the src attribute when provided and no longer injects type="text/javascript", correctly implementing the PR objective. This aligns with HTML5 standards where the type attribute defaults to text/javascript for script elements.

---

91-91: Ternary logic correctly avoids extraneous whitespace.

The ternary operator generates <script>$script</script> when no attributes are present and <script $attr>$script</script> when attributes exist. This works correctly because Escaper\AttrEscaper::__invoke() returns an empty string for empty attribute arrays, which is falsy in PHP.

Do we need this ? I think $attr will be empty string if $attr is empty. Any reason you bring this ?

[koriym]

Without the ternary, an empty $attr produces a trailing space:

  // $attr = '' (empty string)
  "<script $attr>$script</script>"
  // outputs: "<script >$script</script>"

The ternary ensures clean output:

  "<script>$script</script>"
