pretty.gd for JavaScript

A formatter for GDScript that just works!

Usage

Command line

$ npm install -g pretty-gd-js

$ pretty-gd --help
Usage: pretty-gd [options] [path] [files...]

Options:
  -s, --spaces <size>  enforce (or, if -t is also set, convert from) space-based indentation
  -t, --tabs           enforce tab-based indentation
  -a, --auto           auto-detect indentation on each file separately
  -p, --stdio          read from stdin and write it prettified to stdout
  -d, --dir            prettify all *.gd files in [path]
  -w, --watch          automatically prettify any modified *.gd files in [path]
  -v, --version        display version
  -h, --help           display help for command

Godot editor

From the terminal/command line, type the following:

$ cd path/to/godot/project/

$ pretty-gd -w
Watching ./ for changes...

The -w/--watch option alone will not check already existing files, but only those that get modified while pretty-gd -w is running. You can add -d/--dir to also check existing files, like this: pretty-gd -d -w

To disable the annoying "Files have been modified outside Godot" dialog box, go to the following setting and enable it:

Editor -> Editor Settings -> Text Editor -> Behavior -> Auto Reload Scripts on External Change

Note that when pretty-gd modifies a file, the changes doesn't show up in Godot editor right away. External changes are only detected when the Godot window changes focus.

JavaScript API

• prettify(input: string, startInsideString: string = null): string
  • input: string // The string of GDScript to make pretty.
  • startInsideString: string // If set to a string delimiter, assume input is starting inside a string. Default is null.
• isInsideString: string // If last operation ended inside a string, this will be set to the type of quotes(string delimiter) of the string. Otherwise null.
• indent: string // Indentation string. Default is null for auto-detect.
• tabSize: number // Tab size. This will be overwritten if indent is set or detected to be space-based. Default is 4.

To parse a document line by line, remember to feed isInsideString back into the prettify() call as the second parameter.

Keep in mind that indent and tabSize will be preserved between calls to prettify(). If you want to auto-detect for each call, remember to reset these properties to null.

Example

import fs from "node:fs"
import pretty from "pretty-gd-js"

// configure indentation
pretty.indent = "\t"
pretty.tabSize = 4

let file = "my_script.gd"
let input = fs.readFileSync(file)
let output = pretty.prettify(input) // <- This is the main function
fs.writeFileSync(file, output + "\n")

Known Issues

• The Godot editor only checks for file changes when the window changes from unfocused to focused. So if you're running pretty-gd -w in the background, and it prettifies a script you just saved, you won't see the prettified script until you tab out and back into the editor.
• It seems Godot editor only checks the file timestamp down to the second (at least on some systems), meaning if Godot editor saves a file that then gets changed and resaved externally within the same second, Godot editor doesn't detect it as a change. Hence why pretty-gd -w will wait one second before resaving the file.

If you come across any other issues with using this software, please let me know.

Release Notes

1.18.1

• Another bugfix of handling of multiline strings. 🤞

1.18.0

• Making sure that lines ending with a : is followed by a properly indented line.
• Positive numbers/values can now be signed with a +.
• Command line tool renamed to pretty-gd. (pretty.gd still included as an alias.)

1.17.0

• -a/--auto option to auto-detect type of indentation on each file, instead of auto-detecting only on the first encountered file and applying it to all files, if neither -s, -t or -a is set.
• pretty.gd -w will now prettify a file immediately after detecting a change (which can still take up to a second). Instead of delaying the file write to trigger Godot editor's change detection, pretty.gd will write the file straight away and then update it's modification timestamp a second later.
• More strict parsing of number literals.
• A 0 gets added to number literals that start or end with a decimal point or e(exponent marker).
• Redundant leading zeroes gets removed from number literals.
• Negative numbers that come after closing brackets)}], strings, names or other numbers are treated as a subtraction of a unsigned number, thus separating the - and the number.
• Bugfixed handling of multiline strings, so a string delimiter(', ", ''' or """) can now stand alone on a line and the parser will recognize it as either the beginning or end of a string (and not both).

1.16.0

• match, tool, onready, export, setget, remote, master, puppet, remotesync, mastersync and puppetsync are no longer treated as keywords that has to be surrounded by whitespace.

1.15.0

• In --watch mode, file changes will be delayed by one second to ensure Godot editor will detect it as an external change.
• Added --stdio mode for piping data in and out.

1.14.2

• Display version with --version.
• Refactored to use ES modules instead of require.
• Test tool that runs in the browser.
• Fixed bug parsing multi-line strings.

1.14.1

• If --dir or --watch are used without specifying a path, it will default to current directory.
• Command-line tool will safely ignore files and folders it cannot access.

1.14.0

• Number literals, including hexadecimals, will be corrected to lower case.
• Support for all types of strings, including r"raw strings", '''triple-single-quoted strings''' and %"node strings".
• Better handling of multiline strings of any type. API changed slightly.

1.13.1

• Command line options to prettify entire folders.
• not is no longer treated as a keyword that has to be surrounded by whitespace.
• { curly brackets } are now padded inside.
• Vertical spacing gets adjusted. func and class declarations get two blank lines above them. Maximum one consecutive blank line everywhere else.

1.12.0

• Removed eol property. Godot editor always saves with unix-style endings anyway.

1.11.3

• The command line tool now actually works
• Command line options

1.11.0

• Parse indentation based on visual space, rather than character count

1.10.0

• Treat ! as a sign (like - for negative values)

1.9.0

• Opening curly brackets is now its own class (which helps with spacing in enums)

1.7.0

• Recognize operators longer than one character
• Refactored tokenizer

1.3.0

• Added support for _ in numbers
• Added support for @annotations
• Added support for nodepaths starting with &, ^ or %

1.2.0

• Recognizing node paths

0.3.0

• Giving keywords some room

0.2.0

• Fancy icon!

0.1.0
