Plugin for adding custom parsers to extract strings that are to be translated from custom files (.csv, .json etc.). Plugins are registered via [method EditorPlugin.add_translation_parser_plugin] method. To define the parsing and string extraction logic, override the [method parse_file] method in script. The extracted strings will be written into a POT file selected by user under "POT Generation" in "Localization" tab in "Project Settings" menu. Below shows an example of a custom parser that extracts strings in a CSV file to write into a POT. [codeblock] tool extends EditorTranslationParserPlugin func parse_file(path, extracted_strings): var file = File.new() file.open(path, File.READ) var text = file.get_as_text() var split_strs = text.split(",", false, 0) for s in split_strs: extracted_strings.append(s) #print("Extracted string: " + s) func get_recognized_extensions(): return ["csv"] [/codeblock] [b]Note:[/b] If you override parsing logic for standard script types (GDScript, C#, etc.), it would be better to load the [code]path[/code] argument using [method ResourceLoader.load]. This is because built-in scripts are loaded as [Resource] type, not [File] type. For example: [codeblock] func parse_file(path, extracted_strings): var res = ResourceLoader.load(path, "Script") var text = res.get_source_code() # Parsing logic. func get_recognized_extensions(): return ["gd"] [/codeblock] Gets the list of file extensions to associate with this parser, e.g. [code]["csv"][/code]. Override this method to define a custom parsing logic to extract the translatable strings.
