| # FIDL |
| |
| FIDL (**F**uchsia **I**nterface **D**efinition **L**anguage) is the IPC system for Fuchsia. |
| |
| ## Start here |
| |
| The [language tutorials][tutorials] presents a simple "*Hello, world*" client |
| and server, showing the FIDL language definitions and continuing with sections |
| specific to each supported target language (e.g., C++, Dart). |
| |
| Read the [concepts doc][concepts] to get a brief overview of what FIDL is, |
| including some of its design goals, requirements, and workflow. |
| |
| ## Developer Guides |
| |
| * [Running FIDL][cli] — quick CLI overview of the various programs in the |
| FIDL toolchain |
| * [Style Guide][style] |
| * [Designing APIs][designing-apis] |
| * [ABI and API compatibility guide][abi-api-compat] — details the possible |
| transitions for each FIDL type, taking into account ABI and API compatibility |
| * [Maxing Out Pagination][pagination] — help on determining how much data |
| can fit into a single message |
| * [C Family Binding Comparison][c-family] — how to decide, which binding |
| (new C++, HLCPP, or C) to use |
| |
| ## References |
| |
| The [bindings reference][bindings-ref] includes references of generated code in each binding and the FIDL |
| utility libraries available to each language. |
| |
| The [language reference][language-ref] is for everything else, like the |
| [wire format][wire-format] and [RFCs][rfc]. |
