JSONConfigFile 2.0.0 - Godot 4.0

[98teg]

Godot 4.0 migration

This is the pull request where I would explain the status of the Godot 4.0 port. This port is a full rewrite of the original plugin.

Main goals

Reduce the number of exposed classes

In the previous version, each JSON property was exposed as a named class, which could bloat the autocomplete features of the Godot editor. In this migration, the main objective was to reduce them to just two:

• JSONConfigFile: receives a file path and parses it as a JSON.
• JSONSchema: represents the structure of the JSON data.

Simplify the API

This is a code example from version 1.0.0:

var json_config_file = JSONConfigFile.new()
json_config_file.add_property("name", JSONPropertyString.new())
json_config_file.add_property("age", JSONPropertyInteger.new())

var gender = JSONPropertyEnum.new()
gender.set_enum(["MALE", "FEMALE", "NON_BINARY"])
json_config_file.add_property("gender", gender)

var telephone_number = JSONPropertyString.new()
telephone_number.set_pattern("^( |[0-9])+$")
json_config_file.add_property("telephone_number", telephone_number)

var address = JSONPropertyObject.new()
address.add_property("street", JSONPropertyString.new())
address.add_property("number", JSONPropertyInteger.new())
json_config_file.add_property("address", address)

json_config_file.validate(json_config_file_path)

In 2.0.0, it would look like this:

var schema := JSONSchema.new()
schema.add_string("name")
schema.add_int("age")
schema.add_enum("gender").add_value("MALE", 0).add_value("FEMALE", 1).add_value("NON_BINARY", 2)
schema.add_string("telephone_number").set_pattern("^( |[0-9])+$")

var addess := JSONSchema.new()
addess.add_string("street")
addess.add_int("number")
schema.add_dictionary("address").set_schema(addess)

JSONConfigFile.parse_path(json_config_file_path, schema)

Make it similar to Godot's JSON API

I would try to make JSONConfigFile as similar to JSON as possible.

Tasks

In order of priority:

• [x] First Godot 4.0 port.
• [ ] Add Image Property.
• [ ] Add preprocessor
• [x] Add postprocessor.
• [x] Refactor JSONConfigFile's parse method for it to receive the schema.
• [x] Add static method parse_path.
• [ ] Create documentation.
• [ ] Create a demo project.
• [x] Add CI, unit testing & linting.
