Walkthrough

Adds a new nursery GraphQL lint rule useUniqueVariableNames that detects duplicate variable names in GraphQL operations. Introduces the rule implementation, a public UseUniqueVariableNamesOptions struct, registration via declare_lint_rule!, and diagnostics for duplicate names. Adds test fixtures (valid and invalid) exercising the rule and a changeset file for a patch release. Also exposes a new use_unique_variable_names module in the rule options crate.

47-66: Consider tracking the duplicate variable for more precise diagnostics.

The current implementation returns () as state, which means the diagnostic (line 69) will span the entire variable definitions list. Users won't know which specific variable is duplicated.

Consider storing the duplicate variable's range or name in the state so the diagnostic can highlight the exact duplicate.

🔎 Example improvement

Change the state type to track the duplicate:

 impl Rule for UseUniqueVariableNames {
     type Query = Ast<GraphqlVariableDefinitions>;
-    type State = ();
+    type State = TextRange;
     type Signals = Option<Self::State>;
     type Options = UseUniqueVariableNamesOptions;
 
     fn run(ctx: &RuleContext<Self>) -> Option<Self::State> {
         let node = ctx.query();
         let mut found: Vec<String> = Vec::new();
 
         for element in node.elements() {
             if let Some(variable) = element.variable().ok()
                 && let Some(name) = variable.name().ok()
                 && let Some(value_token) = name.value_token().ok()
             {
                 let string = value_token.to_string();
                 if found.contains(&string) {
-                    return Some(());
+                    return Some(value_token.text_range());
                 } else {
                     found.push(string);
                 }
             }
         }
 
         None
     }
 
-    fn diagnostic(ctx: &RuleContext<Self>, _state: &Self::State) -> Option<RuleDiagnostic> {
-        let span = ctx.query().range();
+    fn diagnostic(ctx: &RuleContext<Self>, state: &Self::State) -> Option<RuleDiagnostic> {
         Some(
             RuleDiagnostic::new(
                 rule_category!(),
-                span,
+                *state,
                 markup! {
                     "Duplicate variable name."
                 },
             )
             .note(markup! {
                 "A GraphQL operation is only valid if all its variables are uniquely named. Make sure to name every variable differently."
             }),
         )
     }
 }

This would highlight the specific duplicate variable rather than the entire variable list.

Learning: When defining lint rules (declare_lint_rule!), only specify fix_kind if the rule implements an action(...) function. Rules that only emit diagnostics without a code fix should omit fix_kind. This applies to all Rust lint rule definitions under crates/.../src/lint (e.g., crates/biome_js_analyze/src/lint/...).

1-5: LGTM!

The changeset correctly describes the user-facing addition of the new nursery rule.

crates/biome_rule_options/src/lib.rs (1)

387-387: LGTM!

Module declaration is correctly positioned and follows the alphabetical ordering convention.

crates/biome_graphql_analyze/tests/specs/nursery/useUniqueVariableNames/invalid.graphql (1)

1-4: LGTM!

The test fixtures provide good coverage of duplicate variable scenarios, including multiple duplicates and varying types.

crates/biome_graphql_analyze/tests/specs/nursery/useUniqueVariableNames/valid.graphql (1)

1-3: LGTM!

Valid test fixtures correctly demonstrate queries with uniquely named variables.

crates/biome_rule_options/src/use_unique_variable_names.rs (1)

1-6: LGTM!

The options struct correctly implements all required traits and serde attributes per coding guidelines. An empty struct is appropriate when the rule has no configurable options.
