<brief_description>
Plugin for adding custom parsers to extract strings that are to be translated from custom files (.csv, .json etc.).
</brief_description>
<description>
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].
