function syntaxhighlighter_library_info_build in Syntax Highlighter 8

Implements hook_library_info_build().

NOTE: the assets could have been defined in syntaxhighlighter.library.yml as well using an absolute path, but in that case the library location would have been to be hardcoded, e.g.:

core: js: /libraries/syntaxhighlighter/scripts/shCore.js: { minified: true }

File

./syntaxhighlighter.module, line 65

Syntax highlight code using the SyntaxHighlighter Javascript library.

Code

function syntaxhighlighter_library_info_build() {

  // Make the path absolute.
  //
  // This is needed because:
  // 1. libraries_get_path('syntaxhighlighter') returns the path _relative_ to
  //    the site root path,
  // 2. however hook_library_info_build assume that relative paths for the
  //    assets are relative to the path of the module they are defined in (the
  //    current module),
  // 3. while the external library assets we are defining are NOT from the
  //    current module.
  //
  // So using an absolute path makes sure to look for the assets starting from
  // the site root path.
