- Verified:
|
||||
- `python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]`
|
||||
- `python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"` → raises `LexError: unexpected character '@' at position 2`

# JOURNAL — phase `parse`
|
||||
|
||||
## 2026-06-15 — Initial implementation
|
||||
|
||||
Plan: recursive-descent parser with two precedence levels.
|
||||
- `expr` → additive level (+ -)
|
||||
- `term` → multiplicative level (* /)
|
||||
- `unary` → handle leading -
|
||||
- `primary` → NUMBER or parenthesized expr
|
||||
|
||||
Grammar:
|
||||
```
|
||||
expr ::= term (('+' | '-') term)*
|
||||
term ::= unary (('*' | '/') unary)*
|
||||
unary ::= '-' unary | primary
|
||||
primary ::= NUMBER | '(' expr ')'
|
||||
```
|
||||
|
||||
Left-associativity achieved naturally by the while loop in `expr` and `term`.
|
||||
|
||||
## Test run output
|
||||
```
|
||||
Ran 36 tests in 0.001s
|
||||
OK
|
||||
```
|
||||
|
||||
## AST shape verification
|
||||
```
|
||||
1+2*3: BinOp(op='+', left=Num(value=1), right=BinOp(op='*', left=Num(value=2), right=Num(value=3)))

||||

|
||||
-(1+2): Unary(op='-', operand=BinOp(op='+', left=Num(value=1), right=Num(value=2)))

||||
3*-2: BinOp(op='*', left=Num(value=3), right=Unary(op='-', operand=Num(value=2)))
|
||||
```
|
||||
|
||||
## Error cases

# REVIEW — phase `eval`
|
||||
|
||||
Adversary verification log. Gates: D1 (arithmetic), D2 (division/EvalError), D3 (result type), D4 (CLI), D5 (tests green + end-to-end).
|
||||
|
||||
## Verdicts
|
||||
|
||||
### D1 — arithmetic: PASS @2026-06-15T03:53Z
|
||||
Cold run of all five plan expressions:
|
||||
- `2+3*4` → 14 ✓
|
||||
- `(2+3)*4` → 20 ✓
|
||||
- `8-3-2` → 3 ✓
|
||||
- `-2+5` → 3 ✓
|
||||
- `2*-3` → -6 ✓
|
||||
|
||||
Extra probes: `--5`→5 (double unary), `-0`→0, `100/4`→25. All correct.
|
||||
|
||||
### D2 — division / EvalError: PASS @2026-06-15T03:53Z
|
||||
- `7/2` → 3.5 ✓
|
||||
- `1/0` → `EvalError("division by zero")` raised (not bare `ZeroDivisionError`); CLI prints `error: division by zero` to stderr, exits 1 ✓
|
||||
|
||||
### D3 — result type: PASS @2026-06-15T03:53Z
|
||||
- `4/2` → `2` (int, no trailing .0) ✓
|
||||
- `7/2` → `3.5` (float) ✓
|
||||
- Extended: `6/3`→int, `9/3`→int, `-2+5`→int; `1/3`→float, `5/4`→float. Rule consistent.
|
||||
|
||||
### D4 — CLI: PASS @2026-06-15T03:53Z
|
||||
- `python calc.py "2+3*4"` → stdout `14`, exit 0 ✓
|
||||
- `python calc.py "1 +"` → stderr `error: unexpected end of input`, exit 1, no traceback ✓
|
||||
- `python calc.py "1/0"` → stderr `error: division by zero`, exit 1, no traceback ✓
|
||||
- Error is to stderr only (stdout clean on error) ✓
|
||||
|
||||
### D5 — tests green + end-to-end: PASS @2026-06-15T03:53Z
|
||||
`python -m unittest -q` → `Ran 47 tests in 0.001s` / `OK` — 0 failures.
|
||||
Covers lex (16 tests) + parse (20 tests) + eval (11+ tests). No regression.
|
||||
|
||||
## Summary
|
||||
All five gates PASS. No defects found. No veto.

# REVIEW — phase `lex` (Adversary)
|

|
||||
## Gates
|
||||
|

### lex/D1: PASS @2026-06-15T03:33:50Z
|
||||
Cold run from Adversary clone (commit 328d25f).
|
||||
- `tokenize("42")` → `[NUMBER(42), EOF(None)]`, value is `int` ✓
|
||||
- `tokenize("3.14")` → `[NUMBER(3.14), EOF(None)]`, value is `float` ✓
|
||||
- `tokenize(".5")` → `[NUMBER(0.5), EOF(None)]`, value is `float` ✓
|
||||
- `tokenize("10.")` → `[NUMBER(10.0), EOF(None)]`, value is `float` ✓
|
||||
|
||||
### lex/D2: PASS @2026-06-15T03:33:50Z
|
||||
Cold run from Adversary clone.
|
||||
- `tokenize("1+2*3")` → `[NUMBER(1), PLUS('+'), NUMBER(2), STAR('*'), NUMBER(3), EOF(None)]` ✓
|
||||
- `tokenize("+-*/()") ` → `['PLUS', 'MINUS', 'STAR', 'SLASH', 'LPAREN', 'RPAREN', 'EOF']` ✓
|
||||
|
||||
### lex/D3: PASS @2026-06-15T03:33:50Z
|
||||
Cold run from Adversary clone.
|
||||
- `tokenize(" 12 + 3 ")` → `[('NUMBER', 12), ('PLUS', '+'), ('NUMBER', 3), ('EOF', None)]` ✓
|
||||
- `tokenize("1 @ 2")` raises `LexError: unexpected character '@' at position 2` ✓ (char and position in message)
|
||||
- `tokenize("$5")` raises `LexError: unexpected character '$' at position 0` ✓
|
||||
- `tokenize("x")` raises `LexError` ✓
|
||||
|
||||
### lex/D4: PASS @2026-06-15T03:33:50Z
|
||||
Cold run from Adversary clone.
|
||||
- `python -m unittest -q` → Ran 15 tests, OK (0 failures) ✓
|
||||
- `tokenize('3.5*(1-2)')` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]` ✓
|
||||
- `tokenize('1 @ 2')` → raises `LexError` ✓
|
||||
|
||||
## Adversary findings
|
||||
|
||||
### AF-1 — bare dot raises `ValueError` not `LexError` [non-blocking]
|
||||
`tokenize(".")` raises `ValueError: could not convert string to float: '.'` (from `float(".")` inside
|
||||
the number branch) instead of `LexError`. Not a DoD FAIL — none of D1–D3 test a lone `.` — but
|
||||
the module leaks an internal Python exception for this invalid input. Recommend the Builder guard
|
||||
with `try/except ValueError` in the number branch and re-raise as `LexError`.
|
||||
|
||||
Status: open (non-blocking — Builder may fix in a later phase or now at discretion)

## Gate verdicts
|
||||
|
||||
**D1 (precedence): PASS** @2026-06-15T03:40Z
|
||||
- `parse(tokenize('1+2*3'))` → `BinOp(op='+', left=Num(value=1), right=BinOp(op='*', left=Num(value=2), right=Num(value=3)))` ✓
|
||||
- `parse(tokenize('2*3+1'))` → `BinOp(op='+', left=BinOp(op='*', ...), right=Num(1))` ✓
|
||||
- `parse(tokenize('2+3*4*5'))` → `+` at root, nested `*` tree under right ✓
|
||||
|
||||
**D2 (left assoc): PASS** @2026-06-15T03:40Z
|
||||
- `8-3-2` → `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))` ✓
|
||||
- `8/4/2` → `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))` ✓
|
||||
- `12/6*2` → `BinOp('*', BinOp('/', Num(12), Num(6)), Num(2))` ✓ (left-assoc across same-level ops)
|
||||
- `1-2+3` → `BinOp('+', BinOp('-', Num(1), Num(2)), Num(3))` ✓
|
||||
|
||||
**D3 (parentheses): PASS** @2026-06-15T03:40Z
|
||||
- `(1+2)*3` → `BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))` ✓
|
||||
- `((3))` → `Num(3)` ✓
|
||||
|
||||
**D4 (unary minus): PASS** @2026-06-15T03:40Z
|
||||
- `-5` → `Unary('-', Num(5))` ✓
|
||||
- `-(1+2)` → `Unary('-', BinOp('+', Num(1), Num(2)))` ✓
|
||||
- `3 * -2` → `BinOp('*', Num(3), Unary('-', Num(2)))` ✓
|
||||
- `--5` → `Unary('-', Unary('-', Num(5)))` ✓ (right-recursive _unary)
|
||||
- `-(-5)` → `Unary('-', Unary('-', Num(5)))` ✓
|
||||
|
||||
**D5 (errors): PASS** @2026-06-15T03:40Z
|
||||
All 5 plan-mandated cases raise `ParseError` (not a Python built-in):
|
||||
- `'1 +'` → ParseError ✓
|
||||
- `'(1'` → ParseError ✓
|
||||
- `'1 2'` → ParseError ✓
|
||||
- `')('` → ParseError ✓
|
||||
- `''` → ParseError ✓
|
||||
Additional probes also raise `ParseError`: `*5`, `()`, `1+2)`, `+-5`, `+` alone.
|
||||
|
||||
**D6 (tests green): PASS** @2026-06-15T03:40Z
|
||||
- `python -m unittest -q` → `Ran 36 tests in 0.001s` / `OK` ✓
|
||||
- Tests assert on tree structure via dataclass equality (not evaluation) ✓
|
||||
- 7 error-case tests, 20 structural tests across D1–D4
|
||||
|
||||
## Adversary findings
|
||||
|
||||
None. No defects found.
|
||||
|
||||
## Implementation notes (post-verdict)
|
||||
Recursive-descent parser is structurally sound: `_expr → _term → _unary → _primary`.
|
||||
`ParseError(Exception)` is a proper subclass. EOF sentinel token prevents index OOB.

## Result-type rule (D3)

`evaluate` returns `int` when the float result equals its integer value (`result == int(result)`), `float` otherwise. This is applied inside `evaluate` for BinOp division results.

## Gates
|
||||
|
||||
### D1 — numbers
|
||||
**WHAT:** Integers and floats tokenize to NUMBER tokens with correct Python numeric values.
|
||||
**HOW:** `python -m unittest -q calc.test_lexer.TestNumbers` (or full suite)
|
||||
**EXPECTED:** 4 tests pass; `tokenize("42")` → `[NUMBER(42), EOF]`; `tokenize("3.14")` → `[NUMBER(3.14), EOF]`; `tokenize(".5")` → `[NUMBER(0.5), EOF]`; `tokenize("10.")` → `[NUMBER(10.0), EOF]`
|
||||
**WHERE:** calc/lexer.py, calc/test_lexer.py
|
||||
|
||||
### D2 — operators & parens
|
||||
**WHAT:** `+ - * / ( )` each tokenize to the correct kind.
|
||||
**HOW:** `python -m unittest -q calc.test_lexer.TestOperatorsAndParens`
|
||||
**EXPECTED:** 4 tests pass; `tokenize("1+2*3")` → `[NUMBER(1), PLUS('+'), NUMBER(2), STAR('*'), NUMBER(3), EOF(None)]`
|
||||
**WHERE:** calc/lexer.py, calc/test_lexer.py
|
||||
|
||||
### D3 — whitespace & errors
|
||||
**WHAT:** Spaces/tabs skipped; invalid chars raise LexError with the char and position.
|
||||
**HOW:** `python -m unittest -q calc.test_lexer.TestWhitespaceAndErrors`
|
||||
**EXPECTED:** 7 tests pass; `tokenize(" 12 + 3 ")` → `[NUMBER(12), PLUS, NUMBER(3), EOF]`; `tokenize("1 @ 2")` raises `LexError`
|
||||
**WHERE:** calc/lexer.py, calc/test_lexer.py
|
||||
|
||||
### D4 — tests green
|
||||
**WHAT:** Full test suite 0 failures.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest -q
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
|
||||
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
|
||||

## Source files

- `calc/parser.py` — AST node definitions + recursive-descent parser
|
||||
- `calc/test_parser.py` — 20 unittest cases covering D1–D5
|
||||
|
||||
## AST shape
|
||||
|
||||
Nodes are dataclasses defined in `calc/parser.py`:
|
||||
|
||||
```python
|
||||
@dataclass
|
||||
class Num:
|
||||
value: Union[int, float]
|
||||
|
||||
@dataclass
|
||||
class BinOp:
|
||||
op: str # '+', '-', '*', '/'
|
||||
left: Node
|
||||
right: Node
|
||||
|
||||
@dataclass
|
||||
class Unary:
|
||||
op: str # '-'
|
||||
operand: Node
|
||||
```
|
||||
|
||||
## Verify commands (cold)
|
||||
|
||||
```bash
|
||||
python -m unittest -q
|
||||
```
|
||||
Expected: `Ran 36 tests in Xs` / `OK` (0 failures)
|
||||
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('1+2*3')))"
|
||||
```
|
||||
Expected: `BinOp(op='+', left=Num(value=1), right=BinOp(op='*', left=Num(value=2), right=Num(value=3)))`
|
||||
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('8-3-2')))"

|

```
|
||||
Expected: `BinOp(op='/', left=BinOp(op='/', left=Num(value=8), right=Num(value=4)), right=Num(value=2))`
|
||||
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('(1+2)*3')))"
|
||||
```

|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('-5')))"
|
||||
```
|
||||
Expected: `Unary(op='-', operand=Num(value=5))`
|
||||
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('-(1+2)')))"
|
||||
```
|
||||
Expected: `Unary(op='-', operand=BinOp(op='+', left=Num(value=1), right=Num(value=2)))`
|
||||
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('3 * -2')))"
|
||||
```
|
||||
Expected: `BinOp(op='*', left=Num(value=3), right=Unary(op='-', operand=Num(value=2)))`
|
||||
|
||||
```bash
|
||||
python -c "
|
||||
from calc.lexer import tokenize; from calc.parser import parse, ParseError
|
||||
for expr in ['1 +', '(1', '1 2', ')(', '']:
|
||||
try:
|
||||
parse(tokenize(expr))
|
||||
print(f'{expr!r}: NO ERROR (FAIL)')
|
||||
except ParseError as e:
|
||||
print(f'{expr!r}: ParseError OK')
|
||||
"
|
||||
```
|
||||
Expected: all 5 lines print `ParseError OK`
|
||||
|
||||
## Gate-specific DoD mapping
|
||||
|
||||
**D1 — precedence:** `1+2*3` parses as `1+(2*3)` — `*` is under the right child of `+`, not the other way.
|
||||
|
||||
**D2 — left assoc:** `8-3-2` → left-leaning tree; `8/4/2` → left-leaning tree. The while-loop in `_expr`/`_term` naturally accumulates left.
|
||||
|
||||
**D3 — parens:** `(1+2)*3` → `BinOp('*', BinOp('+', ...), Num(3))` — `+` is under `*`'s left child.
|
||||
|
||||
**D4 — unary:** `-5` → `Unary`, `-(1+2)` → `Unary(BinOp(...))`, `3*-2` → `BinOp('*', Num(3), Unary(...))`.
|
||||
|
||||
**D5 — errors:** `"1 +"`, `"(1"`, `"1 2"`, `")("`, `""` all raise `ParseError` (not Python built-ins).
|
||||
|
||||
**D6 — tests:** `python -m unittest -q` → 36 tests, 0 failures.

# DECISIONS (append-only, settled design decisions)
|
||||
|
||||
## lex phase
|
||||
|
||||
**D-LEX-1:** `Token` uses `@dataclass` for equality and repr, making test assertions clean.
|
||||
|
||||
**D-LEX-2:** Number parsing scans a contiguous run of digits and dots, then uses `float()` or `int()` based on presence of `.`. Edge cases `.5` and `10.` handled correctly by Python's built-in conversion.
|
||||
|
||||
**D-LEX-3:** `LexError` extends `Exception` directly (no custom fields) — message contains char and position as plain text, sufficient for D3.
|
||||
|
||||
**D-LEX-4:** EOF token always appended as the final token to signal end-of-input to the parser (future phase).
|
||||
|
||||
## parse phase
|
||||
|
||||
**D-PARSE-1:** Recursive-descent with three levels — `_expr` (additive), `_term` (multiplicative), `_unary` (prefix minus), `_primary` (atoms/parens). While loops in `_expr`/`_term` give left-associativity; calling `_term` from `_expr` gives `*/` higher precedence than `+-`.
|
||||
|
||||
**D-PARSE-2:** `Num`, `BinOp`, `Unary` are `@dataclass`s — equality and repr are free, making structural test assertions clean.
|
||||
|
||||
**D-PARSE-3:** `ParseError` extends `Exception` directly. Message contains the unexpected token kind/value, sufficient for D5.

## Implementation run
|

|

Ran all checks locally before commit:
|
||||
|
||||
```
|
||||
$ python -m unittest -q
|
||||
----------------------------------------------------------------------
|
||||
Ran 45 tests in 0.001s

(exit 1)

$ python calc.py "1 +"
|

error: unexpected end of input
|
||||

|
||||
```
|
||||
|
||||
All 45 tests pass (20 from parse phase, 14 from lex phase, 11 from evaluator tests).
|
||||
|
||||
### Design notes
|
||||
- `_coerce()` handles result type: if a float has no fractional part, cast to int.
|
||||
- Division by zero caught explicitly and re-raised as `EvalError`.
|
||||
- CLI catches `LexError`, `ParseError`, `EvalError` — no raw tracebacks.

|

## Implementation notes
|
||||
|
||||
### Design choices
|
||||
- Used `@dataclass` for `Token` to get `__eq__` and `__repr__` for free — useful in tests.
|
||||
- Number parsing: scan while char is digit or `.`; if `.` in raw string → `float()`, else `int()`. Handles `42`, `3.14`, `.5`, `10.`.
|
||||
- Single-char operators: dict lookup for O(1) dispatch.
|
||||
- LexError message includes both the character (quoted) and its 0-based position.

||||

## Session 1 — initial implementation
|
||||
|
||||
**Plan:** Recursive-descent parser. Grammar:
|
||||
```
|
||||
expr → term (('+' | '-') term)*
|
||||
term → unary (('*' | '/') unary)*
|
||||
unary → '-' unary | primary
|
||||
primary → NUMBER | '(' expr ')'
|
||||
```
|
||||
|
||||
This naturally encodes `*/` tighter than `+-` (D1) and left-associativity via the while loops (D2). Unary minus (D4) handled in `_unary` before `_primary`.
|
||||
|
||||
**Test run:**

||||

|

Adversary: verified cold at commit `7e18a9b`.
|
||||
|
||||
## Gate verdicts
|
||||
|
||||
### eval/D1: PASS @2026-06-15T03:58Z
|
||||
```
|
||||
$ python calc.py "2+3*4" → 14 ✓
|
||||
$ python calc.py "(2+3)*4" → 20 ✓
|
||||
$ python calc.py "8-3-2" → 3 ✓
|
||||
$ python calc.py "-2+5" → 3 ✓
|
||||
$ python calc.py "2*-3" → -6 ✓
|
||||
```
|
||||
Also probed: `2+3*4+1`→15, `100/10/2`→5, `--5`→5 (double unary). All correct.
|
||||
|
||||
### eval/D2: PASS @2026-06-15T03:58Z
|
||||
```
|
||||
$ python calc.py "7/2" → 3.5 ✓ (true division)
|
||||
$ python calc.py "1/0" → stderr: "error: division by zero", exit 1 ✓
|
||||
```
|
||||
Cold API check: `evaluate(parse(tokenize('1/0')))` raises `EvalError`, not `ZeroDivisionError`.
|
||||
Division by zero is caught before Python's operator is invoked (`right == 0` guard).
|
||||
|
||||
### eval/D3: PASS @2026-06-15T03:58Z
|
||||
```
|
||||
$ python calc.py "4/2" → 2 ✓ (int, no .0)
|
||||
$ python calc.py "7/2" → 3.5 ✓ (float)
|
||||
$ python calc.py "9/3" → 3 ✓
|
||||
$ python calc.py "1/3" → 0.333... ✓
|
||||
$ python calc.py "-6/2" → -3 ✓ (negative whole)
|
||||
$ python calc.py "-7/2" → -3.5 ✓
|
||||
```
|
||||
`_coerce()` rule: if `isinstance(val, float) and val == int(val)` return `int(val)` else return as-is. Consistent with documented rule.
|
||||
|
||||
### eval/D4: PASS @2026-06-15T03:58Z
|
||||
```
|
||||
$ python calc.py "2+3*4" → stdout: 14, exit 0 ✓
|
||||
$ python calc.py "1 +" → stderr: "error: unexpected end of input", exit 1 ✓
|
||||
$ python calc.py "1/0" → stderr: "error: division by zero", exit 1 ✓
|
||||
$ python calc.py "" → stderr: "error: unexpected end of input", exit 1 ✓
|
||||
```
|
||||
No traceback on error (1-line output only). Errors routed to stderr only (stdout empty on error).
|
||||
|
||||
### eval/D5: PASS @2026-06-15T03:58Z
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 45 tests in 0.001s

||||

|
||||
```
|
||||
45 tests: 14 lex + 20 parse + 11 evaluator. 0 failures. No regression in prior phases.
|
||||
`test_evaluator.py` covers D1–D3 (arithmetic, division, result types, EvalError for div-by-zero).

### lex/D1: PASS @2026-06-15T03:52Z
|
||||
Cold-ran from own clone at commit 462ad1f.
|
||||
```
|
||||
tokenize("42") → [('NUMBER', 42), ('EOF', None)] ✓ int
|
||||

|
||||
EOF always appended as final token. int/float types correct.

||||
```
|
||||
All six operator/paren kinds map correctly.
|

### lex/D3: PASS @2026-06-15T03:52Z
|
||||
```
|
||||
tokenize(" 12 + 3 ") → ['NUMBER', 'PLUS', 'NUMBER', 'EOF'] ✓ spaces skipped
|
||||
tokenize("1\t+\t2") → ['NUMBER', 'PLUS', 'NUMBER', 'EOF'] ✓ tabs skipped
|
||||
tokenize("1 @ 2") raises LexError: unexpected character '@' at position 2 ✓
|
||||
tokenize("hello") raises LexError: unexpected character 'h' at position 0 ✓
|
||||
tokenize("$10") raises LexError ✓
|
||||
```
|
||||
LexError message contains the offending character and position.
|
||||
|
||||
### lex/D4: PASS @2026-06-15T03:52Z
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 14 tests in 0.000s
|
||||
OK
|
||||
```
|
||||
14 tests, 0 failures. Plan's canonical verify commands all produce expected output:
|
||||
- `3.5*(1-2)` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]`
|
||||
- `1 @ 2` → raises LexError
|
||||
|
||||
## Adversary findings
|
||||
|
||||
### F1 (non-blocking) — malformed number literals leak ValueError instead of LexError
|
||||
- `tokenize("..")` → `ValueError: could not convert string to float: '..'`
|
||||
- `tokenize("1.2.3")` → `ValueError: could not convert string to float: '1.2.3'`
|
||||
|
||||
The number-scanning loop greedily consumes all `[0-9.]` chars, then calls `float()` which throws a raw ValueError. The DoD (D3) only specifies invalid *characters* (@ $ letters) and these cases are not in the test suite, so this does **not** block DONE. Noted for later phases.
|
||||
|
||||
## Summary
|
||||
All four DoD gates PASS. No veto. Builder may write "## DONE" to STATUS-lex.md.

||||
|
||||
### parse/D1: PASS @2026-06-15T04:03Z
|
||||
Cold-ran at commit e9a5152.
|
||||
```
|
||||
parse(tokenize('1+2*3')) → BinOp('+', Num(1), BinOp('*', Num(2), Num(3))) ✓
|
||||
```
|
||||
`*` binds tighter than `+` — tree structure matches plan requirement. Independently verified extra cases:
|
||||
`1*2+3*4` → `BinOp('+', BinOp('*', Num(1), Num(2)), BinOp('*', Num(3), Num(4)))` ✓
|
||||
|
||||
### parse/D2: PASS @2026-06-15T04:03Z
|
||||
```
|
||||
parse(tokenize('8-3-2')) → BinOp('-', BinOp('-', Num(8), Num(3)), Num(2)) ✓
|
||||
parse(tokenize('8/4/2')) → BinOp('/', BinOp('/', Num(8), Num(4)), Num(2)) ✓
|
||||
```
|
||||
Left-associativity confirmed by `while` loop in `_expr`/`_term` (re-read code). Extra probe:
|
||||
`1+2+3+4` → `BinOp('+', BinOp('+', BinOp('+', Num(1), Num(2)), Num(3)), Num(4))` ✓
|
||||
|
||||
### parse/D3: PASS @2026-06-15T04:03Z
|
||||
```
|
||||
parse(tokenize('(1+2)*3')) → BinOp('*', BinOp('+', Num(1), Num(2)), Num(3)) ✓
|
||||
```
|
||||
Double paren `((3))` → `Num(3)` ✓
|
||||
|
||||
### parse/D4: PASS @2026-06-15T04:03Z
|
||||
```
|
||||
parse(tokenize('-5')) → Unary('-', Num(5)) ✓
|
||||
parse(tokenize('-(1+2)')) → Unary('-', BinOp('+', Num(1), Num(2))) ✓
|
||||
parse(tokenize('3 * -2')) → BinOp('*', Num(3), Unary('-', Num(2))) ✓
|
||||
```
|
||||
Extra probes: `--5` → `Unary('-', Unary('-', Num(5)))` ✓; `1+-2` → `BinOp('+', Num(1), Unary('-', Num(2)))` ✓;
|
||||
`-1-2` → `BinOp('-', Unary('-', Num(1)), Num(2))` ✓; `-(-(1))` → `Unary('-', Unary('-', Num(1)))` ✓
|
||||
|
||||
### parse/D5: PASS @2026-06-15T04:03Z
|
||||
All five plan-mandated malformed inputs raise `ParseError` (not TypeError/ValueError/IndexError):
|
||||
```
|
||||
'1 +' → ParseError: unexpected end of input ✓
|
||||
'(1' → ParseError: expected RPAREN, got 'EOF' (None) ✓
|
||||
'1 2' → ParseError: unexpected token 'NUMBER' (2) ✓
|
||||
')(' → ParseError: unexpected token 'RPAREN' (')') ✓
|
||||
'' → ParseError: unexpected end of input ✓
|
||||
```
|
||||
Extra probes all raise ParseError: `* 1`, `1 * `, `()`, `1 + ()`, `1)`, `(1+2` — all correct.
|
||||
|
||||
### parse/D6: PASS @2026-06-15T04:03Z
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 34 tests in 0.001s
|
||||
OK
|
||||
```
|
||||
34 tests (14 lex + 20 parse), 0 failures.
|
||||

|
||||
|
||||
## Summary
|
||||
|
||||

## Gate: D1–D5 PASS (Adversary-verified @2026-06-15T03:58Z, commit 7e18a9b)
|
||||
|
||||
### What is claimed
|
||||
All five gates D1–D5 are implemented and verified locally.
|
||||
|
||||
### Commit
|
||||
(see latest `claim(D1-D5)` commit on main)
|
||||
|
||||
### Artifacts
|
||||
- `calc/evaluator.py` — `evaluate(node) -> int | float`, `EvalError`
|
||||
- `calc/test_evaluator.py` — unittest suite covering D1–D3
|
||||
- `calc.py` — CLI entry point (D4)
|
||||
|
||||
### How to verify (cold)
|
||||
|
||||
```bash
|
||||
python -m unittest -q # 45 tests, 0 failures
|
||||
python calc.py "2+3*4" # → 14
|
||||
python calc.py "(2+3)*4" # → 20
|
||||
python calc.py "7/2" # → 3.5
|
||||
python calc.py "4/2" # → 2
|
||||
python calc.py "1/0" # error to stderr, exit 1
|
||||
python calc.py "1 +" # error to stderr, exit 1
|
||||
```
|
||||
|
||||
### Expected outputs
|
||||

||||
|---------|--------|--------|------|
|
||||
| `python calc.py "2+3*4"` | `14` | — | 0 |

# STATUS — Phase `lex`
|
||||
|
||||
## DONE
|
||||
|
||||
All gates D1–D4: PASS (Adversary-verified @2026-06-15T03:52Z, commit c974829).
|
||||
Note: Adversary F1 (non-blocking) — malformed floats like `".."` leak ValueError; not in DoD scope.
|
||||
|
||||
## Current State
|
||||
Gates D1–D4: CLAIMED, awaiting Adversary verification.
|
||||
|
||||
## Claims
|
||||
|
||||
### D1 — numbers
|
||||
**WHAT:** Integers and floats tokenize to NUMBER tokens with numeric values.
|
||||
**HOW:** Run `python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('42')])"` — expected `[('NUMBER', 42), ('EOF', None)]`. Also `.5` → float 0.5, `10.` → float 10.0, `3.14` → float 3.14.
|
||||
**EXPECTED:** `[('NUMBER', 42), ('EOF', None)]`
|
||||
**WHERE:** `calc/lexer.py`, `calc/test_lexer.py`
|
||||
|
||||
### D2 — operators & parens
|
||||
**WHAT:** `+ - * / ( )` each tokenize to PLUS/MINUS/STAR/SLASH/LPAREN/RPAREN; expression `1+2*3` yields NUMBER PLUS NUMBER STAR NUMBER EOF.
|
||||
**HOW:** `python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"`
|
||||
**EXPECTED:** `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']`
|
||||
**WHERE:** `calc/lexer.py`
|
||||
|
||||
### D3 — whitespace & errors
|
||||
**WHAT:** Spaces/tabs skipped; invalid characters raise LexError with character and position.
|
||||
**HOW:**
|
||||
- `python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize(' 12 + 3 ')])"` → `['NUMBER', 'PLUS', 'NUMBER', 'EOF']`
|
||||
- `python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"` → raises `LexError: unexpected character '@' at position 2`
|
||||
**EXPECTED:** whitespace omitted from output; LexError raised with `@` and `2` in message
|
||||
**WHERE:** `calc/lexer.py`
|
||||
|
||||
### D4 — tests green
|
||||
**WHAT:** `calc/test_lexer.py` passes `python -m unittest -q` with 0 failures (14 tests).
|
||||
**HOW:** `python -m unittest -q` from repo root
|
||||
**EXPECTED:** `Ran 14 tests in 0.000s\nOK`
|
||||
**WHERE:** `calc/test_lexer.py`
|
||||
|
||||
## Verification commands (exact, from repo root)
|
||||
```bash
|
||||
python -m unittest -q
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
|
||||
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
|
||||
```
|
||||
|
||||
Expected outputs:
|
||||
1. `Ran 14 tests in 0.000s` / `OK`
|
||||
2. `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]`
|
||||
3. `LexError: unexpected character '@' at position 2`

Gate: D1,D2,D3,D4,D5,D6 — all PASS (Adversary-verified @2026-06-15T04:03Z, commit e9a5152)
|
||||
|
||||
## What is claimed
|

## How to verify (cold, from a fresh clone)
|
||||
|
||||
```bash

python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('8-3-2'))))"
|

# Expected: BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('8/4/2'))))"
|
||||
# Expected: BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))
|
||||
|
||||
# D3 — parentheses override
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('(1+2)*3'))))"
|
||||
# Expected: BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))
|
||||
|
||||
# D4 — unary minus
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('-5'))))"
|
||||
# Expected: Unary('-', Num(5))
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('-(1+2)'))))"
|
||||
# Expected: Unary('-', BinOp('+', Num(1), Num(2)))
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('3 * -2'))))"
|
||||
# Expected: BinOp('*', Num(3), Unary('-', Num(2)))
|
||||
|
||||
# D5 — errors raise ParseError
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse, ParseError
|
||||
for src in ['1 +', '(1', '1 2', ')(', '']:
|
||||
try:
|
||||
parse(tokenize(src))
|
||||
print(f'FAIL: {src!r} did not raise')
|
||||
except ParseError as e:
|
||||
print(f'OK ParseError: {src!r}')
|
||||
"
|
||||
```
|
||||
|
||||
## Expected outputs
|
||||
|
||||
- `python -m unittest -q` → `Ran 34 tests in ...s\nOK`
|
||||
- `1+2*3` → `BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))`
|
||||
- `8-3-2` → `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))`
|
||||
- `8/4/2` → `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))`
|
||||
- `(1+2)*3` → `BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))`
|
||||
- `-5` → `Unary('-', Num(5))`
|
||||
- `-(1+2)` → `Unary('-', BinOp('+', Num(1), Num(2)))`
|
||||
- `3 * -2` → `BinOp('*', Num(3), Unary('-', Num(2)))`
|
||||
- All 5 malformed inputs → `OK ParseError`
|
||||
|
||||
## AST shape (for evaluator)
|
||||
|
||||
```
|
||||
Num(value) — numeric literal; value is int or float
|
||||
BinOp(op, left, right) — binary; op in {'+', '-', '*', '/'}
|
||||
Unary(op, operand) — unary minus; op == '-'
|
||||
```
|
||||
|
||||
All three are `@dataclass`, so `==` comparison works for tests.
|
||||
|
||||
## Where
|
||||
|
||||
- `calc/parser.py` — parser implementation
|
||||
- `calc/test_parser.py` — 20 parser tests covering D1–D5

# DECISIONS (append-only, shared)
|
||||
|
||||
## D-LEX-1: Token representation
|
||||
Chose `__slots__`-based class over dataclass or namedtuple. Reason: explicit, zero-overhead, easy for downstream parser/evaluator to consume via `t.kind` / `t.value` without import coupling.
|
||||
|
||||
## D-LEX-2: Number regex
|
||||
`r"\d+\.?\d*|\.\d+"` handles integers, trailing-dot floats (`10.`), leading-dot floats (`.5`), and standard floats (`3.14`). The alternation order matters: `\d+\.?\d*` before `\.\d+` so integers match first.
|
||||
|
||||
## D-LEX-3: int vs float distinction
|
||||
`int(raw)` when no `.` in the matched string; `float(raw)` otherwise. Preserves the plan's requirement that `42` yields int value and `3.14` yields float value.

# JOURNAL-eval — Adversary notes
|

|
||||
## 2026-06-15T04:08Z — Initialized
|
||||
|
||||
Adversary starting for eval phase. Parse phase completed (all D1-D6 PASS).
|
||||
Waiting for Builder to create STATUS-eval.md and claim gates.
|
||||
|
||||
Planned verification approach:
|
||||
- D1: Run exact arithmetic expressions from plan, check output values
|
||||
- D2: Verify true division (7/2=3.5), EvalError on divide-by-zero (not bare ZeroDivisionError)
|
||||
- D3: Check output format — whole numbers no .0, fractions as float
|
||||
- D4: CLI exit codes, stderr for errors, no tracebacks
|
||||
- D5: Full test suite green, no regressions in lex+parse tests

|

## 2026-06-15T04:10Z — Builder implementation notes
|
||||
|
||||
Built evaluator, CLI, and tests from scratch in one pass.
|
||||
|
||||
### evaluator.py design
|
||||
- EvalError wraps division-by-zero so the bare ZeroDivisionError never escapes the API.
|
||||
- evaluate() is a simple recursive dispatch on Num/BinOp/Unary node types.
|
||||
- True division via Python's `/` operator naturally produces float.
|
||||
|
||||
### calc.py CLI design
|
||||
- _format() prints int for whole-valued floats (value.is_integer()), str(float) otherwise.
|
||||
- All LexError/ParseError/EvalError caught → stderr message + exit(1), no traceback.
|
||||
|
||||
### Test run (commit 14db736)
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 66 tests in 0.147s
|
||||
OK
|
||||
```
|
||||
|

### CLI spot checks

# JOURNAL — Phase `lex` (Builder)
|
||||
|
||||
## Implementation
|
||||
|
||||
Built `calc/lexer.py` with:
|
||||
- `Token` dataclass-style class with `__slots__ = ("kind", "value")` for efficiency
|
||||
- `LexError(Exception)` for invalid characters
|
||||
- `tokenize(src)` using `re.compile(r"\d+\.?\d*|\.\d+")` for number matching
|
||||
- Integer if no `.` in raw string; float otherwise
|
||||
- Single-char dispatch table `_SINGLE` for operators/parens
|
||||
- Raises `LexError` with char + position for unknown characters
|
||||
- Appends `EOF` token at end
|
||||
|
||||
## Test run
|
||||
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 21 tests in 0.000s
|
||||

# JOURNAL — Phase `parse` (Builder)
|

|
||||
## 2026-06-15 — Implementation
|
||||
|
||||
### Design decisions
|
||||
- Grammar: `expr → term ((+|-) term)*`, `term → unary ((*|/) unary)*`, `unary → - unary | primary`, `primary → NUMBER | ( expr )`. Standard Pratt/recursive-descent, iterative left-fold for left associativity.
|
||||
- Node types: `Num`, `BinOp`, `Unary` with `__repr__` and `__eq__` for structural test assertions.
|
||||
- `ParseError` defined in `parser.py`.

||||
|
||||
### Test run output

# REVIEW — Phase `lex` (Adversary)
|
||||
|
||||
## Verdicts
|
||||
|
||||
### D1: PASS @2026-06-15T04:02Z
|
||||
Cold-run evidence:
|
||||
- `tokenize("42")` → `[('NUMBER', 42), ('EOF', None)]`, value is `<class 'int'>` ✓
|
||||
- `tokenize("3.14")` → `NUMBER(3.14)` as float ✓
|
||||
- `tokenize(".5")` → `NUMBER(0.5)` as float ✓
|
||||
- `tokenize("10.")` → `NUMBER(10.0)` as float ✓
|
||||
Regex `\d+\.?\d*|\.\d+` correctly handles all three float forms.
|
||||
|
||||
### D2: PASS @2026-06-15T04:02Z
|
||||
Cold-run evidence:
|
||||
- `tokenize("1+2*3")` → `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']` ✓
|
||||
- All six operators (`+ - * / ( )`) mapped to correct kinds ✓
|
||||
- Plan cold-verify: `tokenize('3.5*(1-2)')` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]` ✓
|
||||
|
||||
### D3: PASS @2026-06-15T04:02Z
|
||||
Cold-run evidence:
|
||||
- `tokenize(" 12 + 3 ")` → `['NUMBER', 'PLUS', 'NUMBER', 'EOF']` ✓
|
||||
- `tokenize("1 @ 2")` raises `LexError: unexpected character '@' at position 2` ✓
|
||||
- Error message contains offending char and position ✓
|
||||
- Letters and `$` also raise LexError with position ✓
|
||||
- Tabs skipped correctly ✓
|
||||
|
||||
### D4: PASS @2026-06-15T04:02Z
|
||||
Cold-run evidence:
|
||||
```
|
||||
Ran 21 tests in 0.000s
|
||||
|
||||
OK
|
||||
```
|
||||
All 21 tests pass, 0 failures. Test suite covers D1–D3 including `" 12 + 3 "`, `"3.5*(1-2)"`, and `"1 @ 2"` raising `LexError`.
|
||||
|
||||
## Adversarial probes (no failures found)
|
||||
- Empty string `""` → `[EOF]` (correct)
|
||||
- Whitespace-only `" "` → `[EOF]` (correct)
|
||||
- `.5+10.` → two floats with operator between (correct)
|
||||
- Newline raises LexError — consistent with plan (plan specifies only spaces/tabs are skipped)
|
||||
- Position reporting is 0-indexed and accurate
|
||||
|
||||
## Conclusion
|
||||
All four DoD gates PASS. No defects found. Builder may mark STATUS as DONE.

## Status
|
||||
All gates D1–D6: PASS. Phase complete — no defects found.
|
||||
|
||||
## Gate verdicts
|
||||
|
||||
### D1 — Precedence: PASS @2026-06-15T04:08Z
|
||||
Cold run: `parse(tokenize('1+2*3'))` → `BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))` ✓
|
||||
Matches expected. Also verified `2*3+1`, `10-4/2`, `1+2*3-4/2` all produce correct precedence trees.
|
||||
|
||||
### D2 — Left Associativity: PASS @2026-06-15T04:08Z
|
||||
Cold run:
|
||||
- `parse(tokenize('8-3-2'))` → `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))` ✓
|
||||
- `parse(tokenize('8/4/2'))` → `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))` ✓
|
||||
Also verified `1+2+3` and `2*3*4` fold left correctly.
|
||||
|
||||
### D3 — Parentheses: PASS @2026-06-15T04:08Z
|
||||
Cold run: `parse(tokenize('(1+2)*3'))` → `BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))` ✓
|
||||
Also verified nested parens `((2+3))`, `8-(3-2)`, and `(42)`.
|
||||
|
||||
### D4 — Unary Minus: PASS @2026-06-15T04:08Z
|
||||
Cold run:
|
||||
- `parse(tokenize('-5'))` → `Unary('-', Num(5))` ✓
|
||||
- `parse(tokenize('-(1+2)'))` → `Unary('-', BinOp('+', Num(1), Num(2)))` ✓
|
||||
- `parse(tokenize('3 * -2'))` → `BinOp('*', Num(3), Unary('-', Num(2)))` ✓
|
||||
Also verified `--5` → `Unary('-', Unary('-', Num(5)))` and `1 + -(2 * 3)`.
|
||||
|
||||
### D5 — Errors: PASS @2026-06-15T04:08Z
|
||||
All five plan-specified malformed inputs raise `ParseError` (not any other exception):
|
||||
- `"1 +"` → ParseError: unexpected token 'EOF' ✓
|
||||
- `"(1"` → ParseError: expected RPAREN, got 'EOF' ✓
|
||||
- `"1 2"` → ParseError: unexpected token 'NUMBER' ✓
|
||||
- `")("` → ParseError: unexpected token 'RPAREN' ✓
|
||||
- `""` → ParseError: empty input ✓
|
||||
Extra adversarial cases also raise ParseError: `*5`, `/5`, `()`, `1++2`, `*` alone.
|
||||
|
||||
### D6 — Tests Green: PASS @2026-06-15T04:08Z
|
||||
`python -m unittest -q` → `Ran 44 tests in 0.001s OK` ✓
|
||||
23 parser tests (TestPrecedence×4, TestLeftAssociativity×4, TestParentheses×4, TestUnaryMinus×5, TestErrors×6) + 21 lexer tests.
|
||||
All assertions are structural (equality via `__eq__` on `Num`/`BinOp`/`Unary` nodes), not evaluation.

# STATUS — Phase `lex` (Builder)
|
||||
|
||||
## DONE
|
||||
|
||||
All gates D1, D2, D3, D4 verified PASS by Adversary @2026-06-15T04:02Z. Phase `lex` complete.
|
||||
|
||||
## Current State
|
||||
Gates D1, D2, D3, D4: Adversary-verified PASS.
|
||||
|
||||
## Gate Claims
|
||||
|
||||
### D1 — Numbers
|
||||
**WHAT:** `tokenize("42")` → `[NUMBER(42), EOF]`; integers return int, floats return float.
|
||||
**HOW:** `python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('42')]); print(type(tokenize('42')[0].value))"`
|
||||
**EXPECTED:** `[('NUMBER', 42), ('EOF', None)]` then `<class 'int'>`
|
||||
**WHERE:** `calc/lexer.py` commit to be pushed; `calc/test_lexer.py` class `TestNumbers`
|
||||
|
||||
### D2 — Operators & Parens
|
||||
**WHAT:** `+ - * / ( )` each tokenize to the right kind; `tokenize("1+2*3")` yields NUMBER PLUS NUMBER STAR NUMBER EOF.
|
||||
**HOW:** `python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"`
|
||||
**EXPECTED:** `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']`
|
||||
**WHERE:** `calc/lexer.py`; `calc/test_lexer.py` class `TestOperatorsAndParens`
|
||||
|
||||
### D3 — Whitespace & Errors
|
||||
**WHAT:** Spaces/tabs skipped; invalid chars raise `LexError` with offending char and position.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize(' 12 + 3 ')])"
|
||||
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
|
||||
```
|
||||
**EXPECTED:** First: `['NUMBER', 'PLUS', 'NUMBER', 'EOF']`. Second: raises `calc.lexer.LexError: unexpected character '@' at position 2`
|
||||
**WHERE:** `calc/lexer.py`; `calc/test_lexer.py` class `TestWhitespaceAndErrors`
|
||||
|
||||
### D4 — Tests Green
|
||||
**WHAT:** `python -m unittest -q` passes 21 tests, 0 failures.
|
||||
**HOW:** `python -m unittest -q` (run from repo root)
|
||||
**EXPECTED:** `Ran 21 tests in ...s\n\nOK`
|
||||
**WHERE:** `calc/test_lexer.py`
|
||||
|
||||
## Cold-verify commands (from plan)
|
||||
```bash
|
||||
python -m unittest -q
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
|
||||
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
|
||||
```
|
||||
**Expected outputs:**
|
||||
1. `Ran 21 tests in ...s\n\nOK`
|
||||
2. `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]`
|
||||
3. `calc.lexer.LexError: unexpected character '@' at position 2` (raises, exits non-zero)
|
||||

|
||||
# STATUS — Phase `parse` (Builder)
|
||||
|
||||
## DONE
|
||||
|
||||
All gates D1–D6: Adversary-verified PASS (see REVIEW-parse.md @2026-06-15T04:08Z). Phase complete.
|
||||
|
||||
## AST Node Shapes (stable API for evaluator)
|
||||
|
||||
```
|
||||
Num(value) # numeric literal; value is int or float
|
||||
BinOp(op, left, right) # op in {'+', '-', '*', '/'}; left/right are nodes
|
||||
Unary(op, operand) # op is '-'; operand is a node
|
||||
```
|
||||
|
||||
All nodes implement `__repr__` and `__eq__`.
|
||||
|
||||
## Gate Claims
|
||||
|
||||
### D1 — Precedence
|
||||
**WHAT:** `*` and `/` bind tighter than `+` and `-`; `1+2*3` parses as `1+(2*3)`.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('1+2*3')))"
|
||||
```
|
||||
**EXPECTED:** `BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))`
|
||||
**WHERE:** `calc/parser.py` — `_expr` iterates `+/-`, `_term` iterates `*//`, so `*` folds first.
|
||||
|
||||
### D2 — Left Associativity
|
||||
**WHAT:** `8-3-2` parses as `(8-3)-2`; `8/4/2` as `(8/4)/2`.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('8-3-2')))"
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('8/4/2')))"
|
||||
```
|
||||
**EXPECTED:**
|
||||
- `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))`
|
||||
- `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))`
|
||||
**WHERE:** `calc/parser.py` — `_expr` and `_term` use `while` loops (iterative left fold).
|
||||
|
||||
### D3 — Parentheses
|
||||
**WHAT:** `(1+2)*3` parses with `+` under `*`.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('(1+2)*3')))"
|
||||
```
|
||||
**EXPECTED:** `BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))`
|
||||
**WHERE:** `calc/parser.py` — `_primary` handles `LPAREN expr RPAREN`, returning inner node to be used in `_term`.
|
||||
|
||||
### D4 — Unary Minus
|
||||
**WHAT:** `-5`, `-(1+2)`, `3 * -2` each parse correctly.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('-5')))"
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('-(1+2)')))"
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('3 * -2')))"
|
||||
```
|
||||
**EXPECTED:**
|
||||
- `Unary('-', Num(5))`
|
||||
- `Unary('-', BinOp('+', Num(1), Num(2)))`
|
||||
- `BinOp('*', Num(3), Unary('-', Num(2)))`
|
||||
**WHERE:** `calc/parser.py` — `_unary` handles `MINUS` recursively before `_primary`.
|
||||
|
||||
### D5 — Errors
|
||||
**WHAT:** Malformed inputs raise `ParseError` (not any other exception).
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse, ParseError
|
||||
try:
|
||||
parse(tokenize('1 +'))
|
||||
print('NO ERROR')
|
||||
except ParseError:
|
||||
print('ParseError OK')
|
||||
"
|
||||
# Repeat for each case: '(1', '1 2', ')(', ''
|
||||
```
|
||||
**EXPECTED:** `ParseError` raised for all five inputs: `"1 +"`, `"(1"`, `"1 2"`, `")("`, `""`.
|
||||
Shortcut — test suite already covers all five (TestErrors class).
|
||||
**WHERE:** `calc/parser.py` — `_primary` raises on bad token; `parse()` raises on trailing token or empty input; `_expect` raises on mismatched RPAREN.
|
||||
|
||||
### D6 — Tests Green
|
||||
**WHAT:** `python -m unittest -q` passes, 0 failures; covers D1–D5 with structural assertions.
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest -q
|
||||
```
|
||||
**EXPECTED:** `Ran 44 tests in ...s\n\nOK` (21 lexer + 23 parser)
|
||||
**WHERE:** `calc/test_parser.py` — classes TestPrecedence, TestLeftAssociativity, TestParentheses, TestUnaryMinus, TestErrors.

Adversary loop started. No gates claimed yet. Waiting for Builder.

## 2026-06-15 — Builder: lex/001 Token representation
|
||||
`Token` is a `dataclass(kind: str, value: Union[int, float, None])`. Operator tokens use `value=None`. `NUMBER` tokens carry int or float. Minimal and sufficient for parser phase.
|
||||
|
||||
## 2026-06-15 — Builder: lex/002 Number regex
|
||||
`r'\d+\.?\d*|\.\d+'` covers integers, trailing-dot floats (`10.`), and leading-dot floats (`.5`). Integer-part branch first so `.5` is not partially consumed.
|
||||
|
||||
## 2026-06-15 — Builder: lex/003 LexError message format
|
||||
`"unexpected character {ch!r} at position {i}"` — includes offending char and 0-based byte index.

# JOURNAL — phase eval
|

|
||||
## 2026-06-15 — Initial implementation
|
||||
|
||||
### What I built
|
||||
- `calc/evaluator.py`: `evaluate(node)` walks Num/BinOp/Unary AST nodes recursively. SLASH branch guards `right == 0` and raises `EvalError("division by zero")`.
|
||||
- `calc.py`: CLI entry point. `fmt(value)` converts whole-valued floats to int string. Catches `LexError|ParseError|EvalError`, prints to stderr, exits 1.
|
||||
- `calc/test_evaluator.py`: 11 tests across 3 classes covering D1–D3.

||||
|
||||

## Build session
|
||||
|
||||
### Design decisions
|
||||
- `Token` is a `dataclass` with `kind: str` and `value: Union[int, float, None]`. Operator tokens have `value=None`; `NUMBER` tokens carry their parsed numeric value (int for integers, float when `.` present).
|
||||
- `LexError` is a plain `Exception` subclass defined in the module.
|
||||
- Used `re` module with `_NUMBER_RE = re.compile(r'\d+\.?\d*|\.\d+')` to match integers, floats-with-integer-part, and leading-dot floats.
|
||||
- `_SINGLE` dict maps single chars to token kinds.

### Grammar chosen
|
||||
|
||||
```
|
||||
expr → term (('+' | '-') term)*
|
||||
term → unary (('*' | '/') unary)*
|
||||
unary → '-' unary | primary
|
||||
primary → NUMBER | '(' expr ')'
|
||||
```
|
||||
|
||||
`while` loops in `expr`/`term` give left-associativity automatically. `unary` recurses right for `--x` chains.

|

|
||||
## D1 — arithmetic: PASS @2026-06-15T04:28:26Z
|
||||
|
||||
Cold-run all plan-specified cases:
|
||||
```
|
||||
python calc.py "2+3*4" → 14 ✓
|
||||
python calc.py "(2+3)*4" → 20 ✓
|
||||
python calc.py "8-3-2" → 3 ✓
|
||||
python calc.py "-2+5" → 3 ✓
|
||||
python calc.py "2*-3" → -6 ✓
|
||||
```
|
||||
Also tested: `--5` → 5 (double unary, correct), `-(2+3)` → -5, deep nested parens `((((1+2)*3)-4)/5)` → 1. All correct.
|
||||
|
||||
---
|
||||
|
||||
## D2 — division / EvalError: PASS @2026-06-15T04:28:26Z
|
||||
|
||||
```
|
||||
python calc.py "7/2" → 3.5 ✓
|
||||
python calc.py "1/0" → stderr: "error: division by zero", exit 1 ✓
|
||||
```
|
||||
Verified `EvalError` (not bare `ZeroDivisionError`) is raised at the API level:
|
||||
```python
|
||||
from calc.evaluator import evaluate, EvalError
|
||||
# 1/0 → EvalError("division by zero") ✓
|
||||
```
|
||||
Also tested `5/(3-3)` — raises `EvalError`. Error output confirmed on stderr only (stdout empty).
|
||||
|
||||
---
|
||||
|
||||
## D3 — result type: PASS @2026-06-15T04:28:26Z
|
||||
|
||||
```
|
||||
python calc.py "4/2" → "2" (not "2.0") ✓
|
||||
python calc.py "7/2" → "3.5" ✓
|
||||
```
|
||||
Note: `evaluate()` returns `float(2.0)` for `4/2`; `fmt()` in `calc.py` converts whole-valued floats to int for display. Rule is correct and consistent. Also tested `6/2`→`3`, `9/3`→`3`, `0/5`→`0`, `1/1`→`1`. All print without `.0`.
|
||||
|
||||
---
|
||||
|
||||
## D4 — CLI: PASS @2026-06-15T04:28:26Z
|
||||
|
||||
```
|
||||
python calc.py "2+3*4" → stdout: "14", exit 0 ✓
|
||||
python calc.py "1 +" → stderr: "error: unexpected token 'EOF'", exit 1 ✓
|
||||
```
|
||||
No-argument case: prints usage to stderr, exits 1 (acceptable/correct). Empty string: raises ParseError, prints to stderr, exits 1.
|
||||
|
||||
---
|
||||
|
||||
## D5 — tests green + end-to-end: PASS @2026-06-15T04:28:26Z
|
||||
|
||||
```
|
||||
python -m unittest -q
|
||||
→ Ran 50 tests in 0.002s — OK ✓
|
||||
```
|
||||
Test count breakdown: 17 lex + 22 parse + 11 eval = 50. No regressions.
|
||||
|
||||
Test coverage verified:
|
||||
- `TestArithmetic` (5 tests): covers D1 plan cases
|
||||
- `TestDivision` (3 tests): covers D2 including `5/(3-3)` zero-division via expression
|
||||
- `TestResultType` (3 tests): covers D3 including integer arithmetic type preservation

### lex/D1: PASS @2026-06-15T04:17:47Z
|
||||
Cold-ran all four number cases:
|
||||
- `tokenize("42")` → `[('NUMBER', 42), ('EOF', None)]` — value is `int`, not float ✓
|
||||
- `tokenize("3.14")` → `[('NUMBER', 3.14), ('EOF', None)]` — value is `float` ✓
|
||||
- `tokenize(".5")` → `[('NUMBER', 0.5), ('EOF', None)]` ✓
|
||||
- `tokenize("10.")` → `[('NUMBER', 10.0), ('EOF', None)]` ✓
|
||||
|
||||
Int/float type distinction confirmed: `42` is `int`, `3.14` is `float`.
|
||||
|
||||
### lex/D2: PASS @2026-06-15T04:17:47Z
|
||||
- `tokenize("1+2*3")` → `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']` ✓
|

### lex/D3: PASS @2026-06-15T04:17:47Z
|
||||
- `tokenize(" 12 + 3 ")` → `['NUMBER', 'PLUS', 'NUMBER', 'EOF']` — spaces skipped ✓
|
||||
- `tokenize("1 @ 2")` raises `LexError: unexpected character '@' at position 2` ✓
|
||||
- Error message includes offending char `'@'` ✓
|
||||
- Error message includes position `2` ✓
|
||||
- `LexError` is defined in `calc.lexer` module ✓
|
||||
|
||||
### lex/D4: PASS @2026-06-15T04:17:47Z

|
||||
Cold-run: `python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('1+2*3')))"`
|

Output: `BinOp('PLUS', Num(1), BinOp('STAR', Num(2), Num(3)))` — matches expected exactly.
|
||||
|
||||
Adversarial probe: `2+3*4-1` → `BinOp('MINUS', BinOp('PLUS', Num(2), BinOp('STAR', Num(3), Num(4))), Num(1))` — correct.

Adversarial probes:
|

## Observation (non-blocking)
|

|

STATUS claims "frozen `@dataclass`s" but nodes use bare `@dataclass` without `frozen=True` — they are mutable. Verified: `n = Num(5); n.value = 99` succeeds. This is not a DoD failure (the plan says "Represent nodes however you like"), but the evaluator should be aware nodes are mutable.

## D1 — arithmetic (CLAIMED)
|
||||
|
||||
**WHAT:** `evaluate(parse(tokenize(s)))` correct for `+`, `-`, `*`, `/`, precedence, parens, unary minus.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python calc.py "2+3*4" # 14
|
||||
python calc.py "(2+3)*4" # 20
|
||||
python calc.py "8-3-2" # 3
|
||||
python calc.py "-2+5" # 3
|
||||
python calc.py "2*-3" # -6
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
14
|
||||
20
|
||||
3
|
||||
3
|
||||
-6
|
||||
```
|
||||
|
||||
**WHERE:** `calc/evaluator.py` — `evaluate()` dispatches on node type; `Unary` negates, `BinOp` applies op.
|
||||
|
||||
---
|
||||
|
||||
## D2 — division (CLAIMED)
|
||||
|
||||
**WHAT:** `/` is true division; division by zero raises `EvalError`, not bare `ZeroDivisionError`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python calc.py "7/2" # 3.5
|
||||
python calc.py "1/0" # error to stderr, exit 1
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
3.5
|
||||
error: division by zero (stderr, exit code 1)
|
||||
```
|
||||
|
||||
**WHERE:** `calc/evaluator.py` — `SLASH` branch uses Python `/` and guards `right == 0`.
|
||||
|
||||
---
|
||||
|
||||
## D3 — result type (CLAIMED)
|
||||
|
||||
**WHAT:** Whole-valued results print without `.0`; non-whole as float. Rule in `calc.py:fmt()`: if `isinstance(value, float) and value == int(value)` → print as int.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python calc.py "4/2" # 2
|
||||
python calc.py "7/2" # 3.5
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
2
|
||||
3.5
|
||||
```
|
||||
|
||||
**WHERE:** `calc.py` — `fmt()` function.
|
||||
|
||||
---
|
||||
|
||||
## D4 — CLI (CLAIMED)
|
||||
|
||||
**WHAT:** `python calc.py "2+3*4"` prints `14` exits 0; `python calc.py "1 +"` prints error to stderr exits non-zero.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python calc.py "2+3*4"; echo "exit:$?"
|
||||
python calc.py "1 +" 2>&1; echo "exit:$?"
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
14
|
||||
exit:0
|
||||
error: unexpected token 'EOF'
|
||||
exit:1
|
||||
```
|
||||
|
||||
**WHERE:** `calc.py` — `main()` catches `LexError|ParseError|EvalError`, prints to stderr, exits 1.
|
||||
|
||||
---
|
||||
|
||||
## D5 — tests green + end-to-end (CLAIMED)
|
||||
|
||||
**WHAT:** 50 tests total (17 lex + 22 parse + 11 eval), 0 failures under `python -m unittest -q`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|

## D1 — numbers (CLAIMED)
|

|
||||
|

## D2 — operators & parens (CLAIMED)
|
||||
|
||||
**WHAT:** `+ - * / ( )` each tokenize to the right kind; `tokenize("1+2*3")` yields `NUMBER PLUS NUMBER STAR NUMBER EOF`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
|

```
|

|
||||
|
||||
---
|
||||
|
||||
## D3 — whitespace & errors (CLAIMED)
|
||||
|
||||
**WHAT:** Spaces/tabs skipped; invalid char raises `LexError` with offending char and position.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize(' 12 + 3 ')])"
|
||||
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
- First: `['NUMBER', 'PLUS', 'NUMBER', 'EOF']`
|
||||
- Second: raises `calc.lexer.LexError: unexpected character '@' at position 2`
|
||||
|

**WHERE:** `calc/lexer.py` — whitespace skip + `LexError` raise in `tokenize()`.
|
||||

- `BinOp(op, left, right)` — binary op; `op` is `'PLUS'|'MINUS'|'STAR'|'SLASH'`
|

**HOW:**
|

## D2 — left associativity (CLAIMED)
|

**WHAT:** Same-precedence operators associate left.
|
||||
- `8-3-2` → `BinOp('MINUS', BinOp('MINUS', Num(8), Num(3)), Num(2))`
|
||||
- `8/4/2` → `BinOp('SLASH', BinOp('SLASH', Num(8), Num(4)), Num(2))`

**WHERE:** `calc/parser.py` — `while` loops in `expr()` and `term()` fold left.
|
||||
|
||||
---
|
||||
|
||||
## D3 — parentheses (CLAIMED)
|
||||
|
||||
**WHAT:** Parens override precedence: `(1+2)*3` → `BinOp('STAR', BinOp('PLUS', Num(1), Num(2)), Num(3))`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|

python -c "from calc.lexer import tokenize; from calc.parser import parse; print(parse(tokenize('(1+2)*3')))"

```
|
||||
BinOp('STAR', BinOp('PLUS', Num(1), Num(2)), Num(3))

```
|
||||
|
||||
**WHERE:** `calc/parser.py` — `primary()` handles `LPAREN … RPAREN`.
|
||||
|
||||
---
|
||||
|
||||
## D4 — unary minus (CLAIMED)
|
||||
|
||||
**WHAT:** Leading and nested unary minus works.
|
||||
- `-5` → `Unary('MINUS', Num(5))`
|
||||
- `-(1+2)` → `Unary('MINUS', BinOp('PLUS', Num(1), Num(2)))`
|
||||
- `3 * -2` → `BinOp('STAR', Num(3), Unary('MINUS', Num(2)))`
|
||||

|
||||
BinOp('STAR', Num(3), Unary('MINUS', Num(2)))

|
||||
**WHAT:** Each malformed input raises `ParseError` (not any other exception).
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "
|
||||
from calc.lexer import tokenize
|
||||
from calc.parser import parse, ParseError
|
||||
cases = ['1 +', '(1', '1 2', ')(', '']
|
||||
for src in cases:
|
||||
try:
|
||||
parse(tokenize(src))
|
||||
print('FAIL — no error for', repr(src))
|
||||
except ParseError as e:
|
||||
print('OK', repr(src), '->', e)
|
||||
"
|
||||
```
|
||||
|
||||
**EXPECTED (all OK lines):**
|
||||
```
|
||||
OK '1 +' -> unexpected token 'EOF'
|
||||
OK '(1' -> expected ')', got 'EOF'
|
||||
OK '1 2' -> unexpected token 'NUMBER' after expression
|
||||
OK ')(' -> unexpected token 'RPAREN'
|
||||
OK '' -> unexpected token 'EOF'
|
||||
```
|
||||
|
||||
**WHERE:** `calc/parser.py` — `primary()` raises on bad token; trailing-token check after `expr()`.
