GDScript Toolkit

License: MIT Code style: black

This project provides a set of tools for daily work with GDScript. At the moment it provides:

Installation

To install this project you need python3 and pip. Regardless of the target version, installation is done by pip3 command and for stable releases, it downloads the package from PyPI.

Godot 4

pip3 install "gdtoolkit==4.*"
# or
pipx install "gdtoolkit==4.*"

Godot 3

pip3 install "gdtoolkit==3.*"
# or
pipx install "gdtoolkit==3.*"

master (latest)

Latest version (potentially unstable) can be installed directly from git:

pip3 install git+https://github.com/Scony/godot-gdscript-toolkit.git
# or
pipx install git+https://github.com/Scony/godot-gdscript-toolkit.git

Linting with gdlint (more)

To run a linter you need to execute gdlint command like:

$ gdlint misc/MarkovianPCG.gd

Which outputs messages like:

misc/MarkovianPCG.gd:96: Error: Function argument name "aOrigin" is not valid (function-argument-name)
misc/MarkovianPCG.gd:96: Error: Function argument name "aPos" is not valid (function-argument-name)

Formatting with gdformat (more)

Formatting may lead to data loss, so it's highly recommended to use it along with Version Control System (VCS) e.g. git

To run a formatter you need to execute gdformat on the file you want to format. So, given a test.gd file:

class X:
	var x=[1,2,{'a':1}]
	var y=[1,2,3,]     # trailing comma
	func foo(a:int,b,c=[1,2,3]):
		if a in c and \
		   b > 100:
			print('foo')
func bar():
	print('bar')

when you execute gdformat test.gd command, the test.gd file will be reformatted as follows:

class X:
	var x = [1, 2, {'a': 1}]
	var y = [
		1,
		2,
		3,
	]  # trailing comma

	func foo(a: int, b, c = [1, 2, 3]):
		if a in c and b > 100:
			print('foo')


func bar():
	print('bar')

Parsing with gdparse (more)

To run a parser you need to execute the gdparse command like:

gdparse tests/valid-gd-scripts/recursive_tool.gd -p

The parser outputs a tree that represents your code's structure:

start
  class_def
    X
    class_body
      tool_stmt
      signal_stmt	sss
  class_def
    Y
    class_body
      tool_stmt
      signal_stmt	sss
  tool_stmt

Calculating cyclomatic complexity with gdradon

To run cyclomatic complexity calculator you need to execute the gdradon command like:

gdradon cc tests/formatter/input-output-pairs/simple-function-statements.in.gd tests/gd2py/input-output-pairs/

The command outputs calculated metrics just like Radon cc command does for Python code:

tests/formatter/input-output-pairs/simple-function-statements.in.gd
    C 1:0 X - A (2)
    F 2:1 foo - A (1)
tests/gd2py/input-output-pairs/class-level-statements.in.gd
    F 22:0 foo - A (1)
    F 24:0 bar - A (1)
    C 18:0 C - A (1)
tests/gd2py/input-output-pairs/func-level-statements.in.gd
    F 1:0 foo - B (8)

Using gdtoolkit's GitHub action

In order to setup a simple action with gdtoolkit's static checks, the base action from this repo can be used:

name: Static checks

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

jobs:
  static-checks:
    name: 'Static checks'
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
    - uses: Scony/godot-gdscript-toolkit@master
    - run: gdformat --check source/
    - run: gdlint source/

See the discussion in https://github.com/Scony/godot-gdscript-toolkit/issues/239 for more details.

Development (more)

Everyone is free to fix bugs or introduce new features. For that, however, please refer to existing issue or create one before starting implementation.
