1. Documentation Changes

2 change(s) made:

#2 — Missing documentation for param:: and witness:: usage, .args/.wit file formats, and simc compilation flags

  • Files: docs/getting-started/simplicityhl.md
  • Replaced the brief 'Witness Data' section with a comprehensive 'Parameters and Witnesses' section covering: param:: syntax for compile-time parameters with .args file format and simc --args flag; witness:: syntax for spend-time data with .wit file format; concrete inline examples for both; and simc command-line usage for compiling with parameters, witnesses, or both. Added a link to the detailed Witnesses guide.
  • Affected tasks: hash-lock

#3 — Mandatory type annotations on let bindings not explicitly documented in introductory materials

  • Files: docs/getting-started/simplicityhl.md, docs/simplicityhl-reference/let_statement.md
  • Added a 'Key Syntax Rules' section to the getting-started guide with prominent callouts that all let bindings require explicit type annotations (with correct/incorrect examples), and that all variables are immutable. Also added a blockquote warning in let_statement.md with a concrete correct/incorrect example to make the existing rule more visually prominent.
  • Affected tasks: hash-lock

 **Result:** A Simplicity program, identified by its unique 32-byte Commitment Merkle Root (CMR).
 See "What is the CMR?" below for more information.
 
+### Key Syntax Rules
+
+SimplicityHL looks similar to Rust, but has some important differences:
+
+> **All `let` bindings require explicit type annotations.** SimplicityHL does not have type inference. Omitting the type annotation will cause a compiler error.
+>
+> ```rust
+> let x: u32 = 5;        // correct
+> let x = 5;             // will NOT compile
+> ```
+>
+> ```rust
+> let pk: Pubkey = param::MY_KEY;          // correct
+> let pk = param::MY_KEY;                  // will NOT compile
+> ```
+
+> **All variables are immutable.** There is no `mut` keyword in SimplicityHL.

-### Witness Data +### Parameters and Witnesses

-What is witness? +SimplicityHL contracts receive external data through two mechanisms: parameters (compile-time) and witnesses (spend-time).

-Data provided when spending that the contract can access. +#### Parameters (param::)

+Parameters are values fixed at compile time. They become part of the compiled program and cannot change once the contract is deployed. Use parameters for values that define the contract's rules, such as authorized public keys or hash locks. + Example:

fn main() {
-    let sig: Signature = witness::signature;
-    // Use sig in validation
+    let pk: Pubkey = param::AUTHORIZED_KEY;
+    let sig: Signature = witness::SIGNATURE;
+    let msg: u256 = jet::sig_all_hash();
+    jet::bip_0340_verify((pk, msg), sig);
}

-Witness file format: +Parameters are provided to simc via a JSON .args file: +

{
-  "signature": {
-    "value": "0x...",
+  "AUTHORIZED_KEY": {
+    "value": "0x79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798",
+    "type": "Pubkey"
+  }
+}
+```
+
+Compile with parameters:
+```bash
+simc contract.simf --args contract.args
+```
+
+#### Witnesses (`witness::`)
+
+Witness data is provided at spend time — when someone creates a transaction to spend the contract's funds. Witnesses typically contain signatures, preimages, or other proof data.
+
+**Example:**
+```rust
+fn main() {
+    let sig: Signature = witness::SIGNATURE;
+    let msg: u256 = jet::sig_all_hash();
+    let pk: Pubkey = 0x79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798;
+    jet::bip_0340_verify((pk, msg), sig);
+}
+```
+
+Witness values are provided to `simc` via a JSON `.wit` file:
+
+```json
+{
+  "SIGNATURE": {
+    "value": "0x<64_byte_hex_signature>",
    "type": "Signature"
  }
}

+Compile with witness: +bash +simc contract.simf contract.wit + + +Compile with both parameters and witness: +bash +simc contract.simf --args contract.args contract.wit + + +For detailed information on witness types, Option<>, Either<>, arrays, and more, see the Witnesses guide.

## 2. Compiler Error Message Changes

2 change(s) made:

**#1 — Misleading 'Unclosed delimiter' error when type annotation is missing on let binding**
- Files: src/parse.rs
- Improved the 'Unclosed delimiter' error message to mention common causes, specifically missing type annotations on `let` bindings. When a user writes `let x = 5;` instead of `let x: u32 = 5;`, cascading parse failures cause the enclosing block's closing delimiter to appear missing. The original message ('Unclosed delimiter {') sends developers down the wrong diagnostic path (looking for a missing `}`). The new message explicitly mentions that syntax errors inside the block, such as a missing type annotation, can cause this error and provides the correct syntax.
- Affected tasks: hash-lock

**#1 — Unhelpful 'Expected type, found =' error when type annotation is missing on let binding**
- Files: src/error.rs
- Improved the labeled syntax error message format to include a note about SimplicityHL's mandatory type annotations on `let` bindings. When a user writes `let x = 5;`, the parser expects a type after the (recovered) colon but finds `=`, producing 'Expected type, found ='. While somewhat informative, this does not clearly communicate that a type annotation is required. The new message appends a note explaining the requirement with correct syntax. This affects all labeled syntax errors (not just the type label), but the hint is generally useful language guidance for newcomers.
- Affected tasks: hash-lock

### Error Message Before/After

**Misleading 'Unclosed delimiter' error when type annotation is missing on let binding**

- **Before**: `Unclosed delimiter {`
- **After**: `Unclosed delimiter {. This may be caused by a syntax error inside this block, such as a missing type annotation on a `let` binding. Expected syntax: `let name: Type = value;``

**Unhelpful 'Expected type, found =' error when type annotation is missing on let binding**

- **Before**: `Expected type, found =`
- **After**: `Expected type, found =. Note: all `let` bindings require explicit type annotations (e.g., `let x: u32 = value;`)`

4. Out of Scope Items

Issues identified by the synthesis that require deeper changes than documentation or error message edits.

Documentation editor

  • Improve compiler error message for missing type annotations on let bindings (Rank 1). The compiler currently reports 'Unclosed delimiter / Expected type, found =' instead of clearly indicating a missing type annotation.: This requires changes to the SimplicityHL compiler (simc) parser/error reporting, not documentation. The compiler should detect the pattern 'let =' and produce a targeted error message suggesting the addition of a type annotation. Documentation changes alone cannot fix misleading compiler error messages. As a partial mitigation, the documentation now explicitly warns about this requirement upfront so developers are less likely to encounter the error.

Compiler editor

  • Add a 'Parameters and Witnesses' section to the getting-started guide covering param::, witness::, .args/.wit file format, and simc flags: This is a documentation change, not an error message edit. It requires adding new content to /opt/docs/docs/getting-started/simplicityhl.md, which is outside the scope of compiler error message improvements.
  • Add explicit syntax rules to documentation (e.g., 'all let bindings require type annotations') rather than relying on examples: This is a documentation change, not an error message edit. It requires adding new prose content to language syntax documentation, which is outside the scope of compiler error message improvements.
  • Detect the specific let <ident> = pattern (without colon) and produce a targeted error instead of the generic grammar/syntax errors: This requires changes to compiler parsing logic (adding a new parse rule or validation step to detect the missing-colon pattern specifically), not just editing string literals. The error message improvements made above are a partial mitigation, but a complete fix would need the parser to recognize let <ident> = as a specific error case and emit a dedicated diagnostic.
