version 0.21

  # finds declaration of variable at cursor
  my $declaration = PPIx::EditorTools::FindVariableDeclaration->new->find(
    code =>
      "package TestPackage;\nuse strict;\nBEGIN {
    \$^W = 1;
}\nmy \$x=1;\n\$x++;"
    line => 5,
    column => 2,
  );
  my $location = $declaration->element->location;

Finds the location of a variable declaration.

new()

Constructor. Generally shouldn't be called with any arguments.

find( ppi => PPI::Document $ppi, line => $line, column => $column )

find( code => Str $code, line => $line, column => $column )

Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to process. Searches for the variable declaration and returns a "PPIx::EditorTools::ReturnObject" with the declaration ("PPI::Statement::Variable") available via the "element" accessor.

Croaks with a "no token" exception if no token is found at the location. Croaks with a "no declaration" exception if unable to find the declaration.

This class inherits from "PPIx::EditorTools". Also see App::EditorTools, Padre, and PPI.
