<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.
|
|
Add the extracted strings to argument [code]msgids[/code] or [code]msgids_context_plural[/code] if context or plural is used.
|
|
When adding to [code]msgids_context_plural[/code], you must add the data using the format [code]["A", "B", "C"][/code], where [code]A[/code] represents the extracted string, [code]B[/code] represents the context, and [code]C[/code] represents the plural version of the extracted string. If you want to add only context but not plural, put [code]""[/code] for the plural slot. The idea is the same if you only want to add plural but not context. See the code below for concrete examples.
|
|
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 from a CSV file to write into a POT.
|
|
[codeblock]
|
|
tool
|
|
extends EditorTranslationParserPlugin
|
|
|
|
|
|
func parse_file(path, msgids, msgids_context_plural):
|
|
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:
|
|
msgids.append(s)
|
|
#print("Extracted string: " + s)
|
|
|
|
|
|
func get_recognized_extensions():
|
|
return ["csv"]
|
|
[/codeblock]
|
|
To add a translatable string associated with context or plural, add it to [code]msgids_context_plural[/code]:
|
|
[codeblock]
|
|
# This will add a message with msgid "Test 1", msgctxt "context", and msgid_plural "test 1 plurals".
|
|
msgids_context_plural.append(["Test 1", "context", "test 1 plurals"])
|
|
# This will add a message with msgid "A test without context" and msgid_plural "plurals".
|
|
msgids_context_plural.append(["A test without context", "", "plurals"])
|
|
# This will add a message with msgid "Only with context" and msgctxt "a friendly context".
|
|
msgids_context_plural.append(["Only with context", "a friendly context", ""])
|
|
[/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, msgids, msgids_context_plural):
|
|
var res = ResourceLoader.load(path, "Script")
|
|
var text = res.get_source_code()
|
|
# Parsing logic.
|
|
|
|
|
|
func get_recognized_extensions():
|
|
return ["gd"]
|
|
[/codeblock]
