Tools and Libraries
*******************

.[perex]
Everything that helps you work with NEON: libraries that read and write it, the specification of the format, support in editors, a linter and a playground.


Libraries
=========

- [NEON for PHP |php], the package `nette/neon`
- [NEON for JavaScript |javascript], the package `@nette/neon` for JavaScript and TypeScript
- [NEON for Python |python], the package `nette-neon`

All three decode NEON into values, encode values back, and [edit files |editing] so that their formatting stays as it was.


Specification
=============

The format is written down in a language-neutral [specification |https://github.com/nette/neon-specification] together with a conformance corpus, a set of test cases that every implementation runs, so a file reads the same in each of the libraries. If you are writing a NEON library for another language, the corpus is there for you to use.


Editors
=======

- NetBeans (has built-in support)
- PhpStorm ([plugin |https://plugins.jetbrains.com/plugin/28338-neon])
- Visual Studio Code ([Nette Latte + Neon |https://marketplace.visualstudio.com/items?itemName=Kasik96.latte] or [Nette for VS Code |https://marketplace.visualstudio.com/items?itemName=franken-ui.nette-for-vscode])
- Sublime Text 3 ([plugin |https://github.com/FilipStryk/Nette-Latte-Neon-for-Sublime-Text-3])
- Sublime Text 2 ([plugin |https://github.com/Michal-Mikolas/Nette-package-for-Sublime-Text-2])
- VIM ([plugin |https://github.com/fpob/nette.vim])
- Emacs ([plugin |https://github.com/Fuco1/neon-mode])
- Prism.js ([integrated language |https://prismjs.com/#supported-languages])


Checking Files
==============

Each library comes with the command `neon-lint`, which reports the errors of `.neon` files with their line and column, in your editor, in CI or after an AI agent. It works the same in all three, see [NEON for PHP |php#Checking Files: neon-lint].


Playground
==========

You can try NEON right in your browser in the [playground |https://fiddle.nette.org/neon/].
