# 🦑 ink! Analyzer

A library for semantic analysis of [ink!](https://use.ink/) smart contract code.

It implements utilities for performing semantic analysis of ink! smart contract code.
It therefore implements the core functionality of ink! analyzer at a high level.

It currently implements an [Analysis](/crates/analyzer/src/analysis.rs) entry point that accepts a string representation (`&str`) of ink! smart contract code as input and defines associated methods that compute:

- [diagnostics](/crates/analyzer/src/analysis/diagnostics.rs) - errors and warnings based on ink! semantic rules.
- [completions](/crates/analyzer/src/analysis/completions.rs) - completion suggestions for ink! attribute macros and arguments.
- [code/intent actions](/crates/analyzer/src/analysis/actions.rs) - contextual assists for adding relevant ink! attribute macros and arguments.
- [hover content](/crates/analyzer/src/analysis/hover.rs) - descriptive/informational text for ink! attribute macros and arguments.

**NOTE:** 🚧 This project is still work in progress, check back over the next few weeks for regular updates.

## Installation

Run the following Cargo command in your project directory

```shell
cargo add ink-analyzer
```

## Usage

### Example:
Analyzing ink! smart contract code.

```rust
use ink_analyzer::{Analysis, TextSize, TextRange};

fn do_analysis() {
    // Smart contract code.
    let code = r#"
        #[ink::contract]
        mod my_contract {

            #[ink(storage)]
            pub struct MyContract {
                value: bool,
            }

            // --snip--
        }
    "#;

    // Creates analysis snapshot.
    let analysis = Analysis::new(code);

    // Computes diagnostics.
    let diagnostics = analysis.diagnostics();
    dbg!(&diagnostics);

    // Sets the cursor position.
    let position = TextSize::from(9);

    // Computes completions.
    let completions = analysis.completions(position);
    dbg!(&completions);

    // Computes code/intent actions.
    let actions = analysis.actions(position);
    dbg!(&actions);

    // Sets the focus range.
    let range = TextRange::new(position, TextSize::from(25));

    // Gets hover content.
    let hover = analysis.hover(range);
    dbg!(&hover);
}
```

## Documentation

[https://docs.rs/ink-analyzer/latest/ink_analyzer/](https://docs.rs/ink-analyzer/latest/ink_analyzer/)

Or you can access documentation locally by running the following command from the project root

```shell
cargo doc -p ink-analyzer-ir --open
```

## Testing

You can run unit and integration tests for all the core functionality by running the following command from the project root

```shell
cargo test -p ink-analyzer-ir
```

Implementations of the unit tests (and hence a good overview of the current functionality) can be found in the [diagnostics submodule](/crates/analyzer/src/analysis/diagnostics.rs) of the [ink-analyzer crate](/crates/analyzer).
