Docs: Add bug report for parser operator precedence

[logbie]

Adds a detailed bug report documenting a critical parser issue related to operator precedence in function call arguments.

The current parser incorrectly groups binary operations in arguments. For example, an expression like factorial with n minus 1 is evaluated as (factorial(n)) - 1 instead of the expected factorial(n - 1). This parsing error leads to incorrect behavior and can cause infinite recursion in recursive functions.

This report provides a thorough analysis of the root cause, outlines the impact, and proposes potential solutions to inform an eventual fix.

Walkthrough

This PR addresses operator precedence issues in recursive function calls by enabling early action registration in the parser, adding special-case handling for loop variables in the typechecker, updating repeat-while loop control flow in the interpreter, and providing comprehensive test coverage through multiple Nexus workflow scripts validating recursion, loops, string concatenation, and control flow.

Changes

Cohort / File(s)	Summary
Parser & Recursion Support src/parser/mod.rs	Moved action name insertion into known_actions to occur before body parsing, enabling recursive action calls to be recognized during parsing.
Typechecker & Symbol Management src/typechecker/mod.rs	Added runtime symbol registration for "count" as a Number type in loop contexts and expanded special-case variable handling to treat "count" similarly to "loopcounter" during type inference.
Interpreter Loop Control src/interpreter/mod.rs	Updated repeat-while loop branch to initialize _last_value, capture block execution results, and branch on ControlFlow variants (Break, Continue, Exit, Return) instead of ignoring results.
Core Nexus Workflow Updates Nexus/nexus.wfl	Adjusted recursive factorial expression to enforce explicit precedence by wrapping recursive call in parentheses: from n times factorial with n minus 1 to n times (factorial with (n minus 1)).
Factorial Test Implementations Nexus/test_factorial.wfl, Nexus/test_factorial_inline.wfl, Nexus/test_factorial_parens.wfl	Added three factorial implementations: one with step-by-step logging, one with inline recursion, and one with explicit parentheses; each includes test scaffolding.
Loop & Control Flow Tests Nexus/test_nested_loops.wfl, Nexus/test_skip_loop.wfl, Nexus/nexus_partial.wfl	Added tests validating nested loop break behavior, skip statement behavior in loops, repeat-until loops, and forever loops with break conditions.
String & Variable Tests Nexus/test_concat.wfl, Nexus/test_zero_concat.wfl	Added string concatenation tests combining literals with numeric variables via log actions and file I/O.
Function Call & Parity Tests Nexus/test_simple_call.wfl, Nexus/test_even_check.wfl, Nexus/test_inline_even.wfl	Added tests for function calls (direct, assigned to variable, invoked via variable), even/odd detection via action definitions, and inline expression evaluation.
Documentation & Configuration parserbug.md, .claude/settings.local.json	Added detailed bug report documenting operator precedence parsing issues in function arguments with proposed fixes and test cases; added Bash(cargo run:*) to allowed command patterns.
Temporary Files temp1.txt, temp2.txt	Added two temporary text files containing placeholder content.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~35 minutes

• src/parser/mod.rs: Verify timing of action name insertion doesn't break other parsing logic or cause issues with mutual recursion or forward references.
• src/typechecker/mod.rs: Ensure "count" special-casing correctly handles all loop contexts and doesn't create unintended type-checking side effects; review interaction with existing "loopcounter" handling.
• src/interpreter/mod.rs: Validate ControlFlow branching logic in repeat-while loops covers all cases (Break, Continue, Exit, Return) and properly preserves/returns values.
• parserbug.md: Detailed technical documentation meriting careful review for accuracy of problem statement, root cause analysis, and proposed solutions.
• Nexus test files: Multiple new test files following similar patterns (repetitive structure reduces per-file effort); verify each test correctly validates intended behavior and precedence/control-flow semantics.

Poem

🐰 Recursion's recursive embrace, now parsing with grace,
Actions call themselves, no infinite space,
Loops count with pride, control flows so true,
Tests pile up high—a verification queue!
With parentheses clear, precedence stays right,
The Nexus now shines with computational light. ✨

⚠️ Outside diff range comments (1)

src/interpreter/mod.rs (1)

2833-2876: RepeatWhileLoop discards _last_value on normal completion (inconsistent with other loops)

Inside the RepeatWhileLoop arm you now track _last_value per iteration and correctly propagate it for Exit and Return, but the final return still uses Value::Null, so callers never see the last body value when the loop ends normally. The other loop variants (WhileLoop, RepeatUntilLoop, ForeverLoop, MainLoop) all return the last body value on normal completion.

To make RepeatWhileLoop consistent with those semantics and with the new _last_value tracking, consider:

-                Ok((Value::Null, ControlFlow::None))
+                Ok((_last_value, ControlFlow::None))

🧹 Nitpick comments (8)

src/parser/mod.rs (1)

4224-4227: Early known_actions registration correctly enables recursive action calls

Registering the action name before parsing the body is consistent with how parse_binary_expression uses known_actions to recognize name with ... as Expression::ActionCall, so this should unblock recursive calls inside the same action without impacting non‑recursive ones.

One minor behavioral shift: if parsing the body later fails (e.g., missing end action), the name will now remain in known_actions even though no ActionDefinition is produced. That only affects parsing heuristics, but if you want known_actions to strictly mirror successfully parsed actions, you could either:

• defer insertion until after successfully consuming end action, or
• roll back the insert when parse_action_definition returns an error.

Also, since this changes when calls are classified as action calls, double‑check that any bytecode or interpreter logic that relies on the AST shape for actions behaves as expected for recursive definitions. As per coding guidelines, ensure any required bytecode updates/tests accompany this parser change.

Nexus/test_zero_concat.wfl (1)

3-15: Zero-concat regression test is sound; consider optional error handling

The script correctly exercises concatenation of a numeric 0 through log_test, writes to a log file, and closes the handle, so it should be effective as a focused regression test.

If you want to align more strictly with the WFL guideline of comprehensive error handling around I/O, you could wrap the open file and logging calls in a try/when/otherwise block, but that’s optional for this small Nexus harness script.

As per coding guidelines, WFL programs are encouraged to use structured try/when/otherwise around fallible file operations.

Nexus/test_skip_loop.wfl (1)

22-23: Clarify expected result comment.

The comment on line 23 is slightly confusing. The loop processes count2 values 1, 2, 3, 4 (while count2 < 5), and skips even numbers (2, 4). The odd numbers 1 and 3 sum to 4, which matches the stated expectation. However, the phrasing "loop only goes to 4" might be clearer as "loop processes values 1 through 4" to distinguish between the loop counter and the comparison value.

Apply this diff:

-display "Expected: 1+3+5 = 9, but loop only goes to 4, so actual should be 1+3 = 4"
+display "Expected: Loop processes 1-4, skips evens (2,4), adds odds (1+3) = 4"

Nexus/test_nested_loops.wfl (1)

1-26: Nested loop break behavior looks correct; header comment slightly misleading

The loop logic and final check correctly verify that break exits only the inner loop and that the outer loop runs three times. The header comment mentions “break and exit”, but this script only covers the break case; consider updating the comment or adding an exit loop variant here for clarity and future readers.

Nexus/test_factorial_parens.wfl (1)

1-14: Factorial implementation is correct; consider adding an assertion-style check

The recursive definition using n times (factorial with (n minus 1)) cleanly exercises the precedence you want to validate. To make this a stronger regression test, consider adding a check if result is equal to 120 with PASS/FAIL output instead of only printing the raw result, so tooling can automatically detect regressions.

Nexus/test_factorial.wfl (1)

1-22: Trace-style factorial test is sound; optional: add a concrete expected-value check

The recursive implementation and logging of intermediate values are correct and useful for debugging. If you want this script to double as an automated test, you could add a small check if fact3 is equal to 6 with PASS/FAIL output after computing factorial with 3, similar to other Nexus tests.

🔇 Additional comments (11)

.claude/settings.local.json (1)

33-34: Addition of cargo run permission is appropriate.

The new "Bash(cargo run:*)" permission aligns with existing cargo-related permissions and is appropriate for CI/test workflows. The pattern is consistent with other command patterns in the allow list.

Nexus/test_even_check.wfl (1)

3-18: Even-check test script looks correct and idiomatic

The action and calls use the expected WFL arithmetic and display ... with ... patterns, and should give clear diagnostics for numbers 1–5 without needing extra error handling.

src/typechecker/mod.rs (2)

1521-1522: LGTM - Consistent special-case handling for loop variables.

The extension of special-case handling to include "count" alongside "loopcounter" is consistent with the existing pattern. Both variables are correctly typed as Number and avoid undefined-variable errors during type inference.

---

648-651: The hardcoded "count" variable name is correct and follows WFL language specification.

WFL documentation explicitly defines that count loops automatically provide a loop variable named count, which is not user-configurable. The specification states: "The loop variable is always named count and is lexically scoped to the loop body. Currently, there is no syntax to rename or alias the loop variable - it's always count." Unlike ForEachLoop where the item name is user-specified in syntax (for each <name> in <collection>), CountLoop has no such syntax parameter—the variable name is fixed by language design.

Nexus/test_inline_even.wfl (1)

1-25: LGTM - Clear test validation of inline expressions.

The test correctly validates even/odd detection using the inline expression ((num divided by 2) times 2) is equal to num. The test cases cover both even (2) and odd (1, 3) numbers with clear expected outcomes labeled in the display statements.

Nexus/test_factorial_inline.wfl (1)

8-8: Test depends on parser bug fix for correct behavior.

Line 8 uses the inline expression n times factorial with n minus 1, which is the exact pattern described in parserbug.md as being misparsed. Without the parser fix, this will be incorrectly parsed as (n * factorial(n)) - 1, causing infinite recursion. This test validates the fix but will fail until the parser bug is addressed.

Based on the PR objectives, this appears to be a documentation PR for the bug rather than a fix. Should this test be marked as expected-to-fail or skipped until the parser is fixed?

Nexus/nexus_partial.wfl (1)

1-44: LGTM - Pragmatic workaround test while parser bug exists.

This test script provides valuable validation of loop constructs (repeat-until and forever with break) while explicitly skipping the problematic even number check that relies on inline expressions. The explicit SKIP marking (line 13) documents the known limitation until the parser bug is fixed.

parserbug.md (1)

1-339: Excellent bug documentation with comprehensive analysis.

This is an exceptionally thorough bug report that includes:

• Clear problem statement and examples
• Detailed root cause analysis with step-by-step trace
• Impact analysis covering affected code patterns
• Multiple proposed fixes with trade-offs
• Test cases to validate the fix
• Practical workarounds for users

The document will serve as valuable reference for implementing the parser fix.

Nexus/test_concat.wfl (1)

1-20: LGTM - Clear concatenation test progression.

The test systematically validates string concatenation with numbers through progressively complex examples:

1. Simple string
2. String with a number variable
3. Multiple concatenations in one expression

This provides good coverage of concatenation behavior.

Nexus/test_simple_call.wfl (1)

11-19: Use documented first-class action syntax instead of simplified form.

WFL supports first-class actions through its "First-Class Actions and Action Handles" feature, but Tests 2 and 3 use non-standard syntax. The standard pattern is store handle as get action name from object, then store result as perform handle with args. Line 13's direct assignment (store f as sum_two) and line 18's direct call (store result2 as f with 10 and 20) do not follow documented syntax and may not work as intended. Either update to use the proper get action and perform keywords, or confirm this test is validating error handling for unsupported syntax.

Nexus/nexus.wfl (1)

295-303: Explicit parentheses in recursive factorial correctly enforce precedence

Switching to give back n times (factorial with (n minus 1)) with the added comment makes the intended grouping unambiguous and avoids the precedence misparse for factorial with n minus 1. This is a clear, low-risk workaround that keeps the integration test stable while the parser bug exists.
