# pretty.gd for JavaScript ![pretty godot](./images/pretty.png) 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 -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 #### Example ```js import fs from "node:fs" import Prettifier from "pretty-gd-js" const prettifier = new Prettifier() // configure indentation prettifier.indent_str = "\t" prettifier.tab_size = 4 let filename = "my_script.gd" let input = fs.readFileSync(filename) let output = prettifier.prettify(input) // <- This is the main function fs.writeFileSync(filename, 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.

(`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](https://github.com/poeticAndroid/pretty-gd-js/blob/main/test/test.html). - 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 Initial release!
