Write script to automate replacement of deprecated functions where possible

I have created a project to automate the replacement of deprecated functions, see the function_replace tool at https://github.com/grom358/d8codetools :)

@grom358, great script!. I would like to use the script in #2223435: Do not use t() in block plugins anymore. Initially I made a bash script, but now I run into static functions where the replacement should not take place and your script handles this nicely t() calls should be replaced by $this->t() calls in a subset of files. Would it be feasible to modify the script to make the class and alias optional? I need to call the script for a subset of classes, located in .../Plugin/... directories.

@Sutharsan yes that is doable. Its built on Pharborist. The API is still a work in progress, but you can tell if the parent method is static by using $node->getParent() until you get to ClassMethodNode (if the call is inside a class method, otherwise the parent could be a FunctionDeclarationNode or even StatementBlockNode if its a top level statement). Then $method->modifiers->static !== NULL will tell you its a static method.

// Untested code to replace your t() calls to $this->t() calls
$tree = Parser::parseFile($filename);
$function_call_nodes = $tree->find('\Pharborist\FunctionCallNode');
foreach ($function_call_nodes as $function_call_node) {
  if ($function_call_node->functionReference instanceof NamespacePathNode && $function_call_node->functionReference->getChildCount() === 1) {
    $name = (string) $function_call_node->functionReference;
    if ($name === 't') {
      $pos = $name->getSourcePosition();
      $replacement = new TokenNode(T_STRING, '$this->t', $pos->lineNo, $pos->colNo); // @todo Fix hacky conversion
      $function_call_node->replaceChild($replacement, $function_call_node->functionReference);
    }
  }
}
