## What it is
Taplo is a versatile TOML v1.0.0 toolkit written in Rust, providing a parser, analyzer, and formatter usable as a library, CLI, VS Code extension, and language server. It supports syntactic and JSON-schema-based validation with fine-grained formatting options.

## Use cases
- parse and validate TOML files
- format TOML configuration files
- lint TOML against JSON schemas
- add TOML language server support to an editor
- manipulate TOML documents programmatically in Rust

## When to choose
- you need a fast, spec-compliant TOML parser in Rust
- you want TOML formatting and validation in CI or an editor
- you need a TOML language server with JSON schema support

## When to avoid
- you need a different configuration format like YAML or JSON
- you need guaranteed TOML 1.0.0 compliance test-suite certification, which does not yet exist

## Facets
- artifact type: library
- maturity: active
- function: parser, formatter, linter, cli, editor
- domain: developer-tools, files, parsers, text-editors
- platform: rust, cross-platform, cli, editor-plugin
- tags: toml, language-server, -schema-validation, code-formatting
