- [x] Create calc/ package (calc/__init__.py)
|

## Adversary findings
|
||||
|
||||
- [ADVISORY, non-blocking] `tokenize("1.2.3")` raises bare `ValueError` instead of
|
||||
`LexError`. Greedy dot-consuming loop accumulates "1.2.3", then `float()` crashes.
|
||||
Not required by DoD (D3 only mandates LexError for character-level invalids like @/$
|
||||
/letters). Advisory for future phases — parser/evaluator should not assume clean
|
||||
numeric input from a partially-broken source. (Found 2026-06-15T05:54:37Z)

# DECISIONS — shared (append-only)
|

|
||||
## 2026-06-15 — Token representation
|
||||
|
||||
Used a dataclass with `kind: str` and `value` (Any). This lets NUMBER store int or float, and other tokens store the character string. Simple and sufficient for the parser phase.
|
||||
|
||||
## 2026-06-15 — Number parsing
|
||||
|
||||
Integers → int, floats (containing `.`) → float. Handles `.5`, `10.`, `3.14`.
|
||||
|
||||
## 2026-06-15 — Advisory: multi-dot number strings
|
||||
|
||||
`tokenize("1.2.3")` produces a bare `ValueError` from `float()` rather than a `LexError` because the greedy digit+dot scanner consumes the whole string before conversion. DoD only requires LexError for character-level invalids, so this is not a phase-lex defect. Parser phase should guard against malformed numeric literals if needed.

# JOURNAL — phase eval (Adversary)
|
||||
|
||||
## 2026-06-15T06:00Z — Phase initialized
|
||||
|
||||
Adversary initialized eval phase tracking files. Parse phase is DONE (all D1-D6 PASS).
|
||||
Awaiting Builder to implement eval phase (evaluator.py, calc.py, test_evaluator.py).
|
||||
|
||||
## 2026-06-15 — Builder implementation complete
|
||||
|
||||
Implemented `calc/evaluator.py`, `calc.py`, `calc/test_evaluator.py` in one pass. All 50 tests green. All 5 gates claimed.
|
||||
|
||||
Key implementation notes:
|
||||
- Division guard prevents bare `ZeroDivisionError`: `if right == 0: raise EvalError("division by zero")`
|
||||
- `format_result(float)`: `int(value)` branch strips `.0` when `value == int(value)`
|
||||
- CLI catches `LexError|ParseError|EvalError`, writes to stderr, exits 1
|
||||
|
||||
All CLI spot-checks match plan expected outputs exactly.

# JOURNAL — phase lex
|
||||
|
||||
## Session start 2026-06-15
|
||||
|
||||
Read phase plan. Mission: build calc/lexer.py with tokenize() and test suite.
|
||||
|
||||
Token kinds: NUMBER, PLUS, MINUS, STAR, SLASH, LPAREN, RPAREN, EOF.
|
||||
Token has at least kind and value.
|
||||
LexError for invalid characters.
|
||||
|
||||
Starting implementation.
|
||||
|
||||
## Implementation complete
|
||||
|
||||
Created:
|
||||
- calc/__init__.py (empty package marker)
|
||||
- calc/lexer.py (Token dataclass, LexError, tokenize)
|
||||
- calc/test_lexer.py (13 tests covering D1-D3)
|
||||
|
||||
Test run:
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 13 tests in 0.000s
|
||||
OK
|
||||
```
|
||||
|
||||
Plan verification commands:
|
||||
```
|
||||
$ 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')"
|
||||
calc.lexer.LexError: unexpected character '@' at position 2
|
||||
```
|
||||
|
||||
Claimed D1 (sha 8cb68d2), D2 (sha ac701e0), D3 (sha ed9b554), D4 (sha 6544e45).
|

# JOURNAL — phase parse
|
||||
|
||||
## 2026-06-15 — Initial implementation
|
||||
|
||||
### Approach
|
||||
Recursive-descent parser with three precedence levels:
|
||||
- `_expr`: handles `+` and `-` (lowest)
|
||||
- `_term`: handles `*` and `/` (medium)
|
||||
- `_unary`: handles unary `-` (right-associative by recursion)
|
||||
- `_primary`: handles `NUMBER` and `(expr)` (highest)
|
||||
|
||||
Left associativity falls out naturally from the while-loop pattern in `_expr` and `_term`.
|
||||
|
||||
### Test run
|
||||
```
|
||||
python -m unittest -q
|
||||
Ran 31 tests in 0.001s
|
||||
OK
|
||||
```
|
||||
|
||||
### AST shape verification
|
||||
```
|
||||
D1 1+2*3: BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))
|
||||
D2 8-3-2: BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))
|

D2 8/4/2: BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))
|
||||
D3 (1+2)*3: BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))
|
||||
D4 -5: Unary('-', Num(5))
|
||||
D4 -(1+2): Unary('-', BinOp('+', Num(1), Num(2)))
|
||||
D4 3*-2: BinOp('*', Num(3), Unary('-', Num(2)))
|
||||
D5 '1 +': ParseError: unexpected token 'EOF' (None); expected number or '('
|
||||
D5 '(1': ParseError: expected 'RPAREN' but got 'EOF' (None)
|
||||
D5 '1 2': ParseError: unexpected token 'NUMBER' (2) after expression
|
||||
D5 ')(': ParseError: unexpected token 'RPAREN' (')'); expected number or '('

# REVIEW — phase lex (Adversary)
|

|
||||
## Gate verdicts
|
||||
|
||||
### D1: PASS @2026-06-15T05:54:37Z
|
||||
Cold run from work-adv clone:
|
||||
```
|
||||
tokenize("42") → [('NUMBER', 42), ('EOF', None)] — int type ✓
|
||||
tokenize("3.14") → [('NUMBER', 3.14), ('EOF', None)] — float type ✓
|
||||
tokenize(".5") → [('NUMBER', 0.5), ('EOF', None)] — float type ✓
|
||||
tokenize("10.") → [('NUMBER', 10.0), ('EOF', None)] — float type ✓
|
||||
```
|
||||
Plan requires `tokenize("42")` → `[NUMBER(42), EOF]` with numeric value. CONFIRMED.
|
||||
|
||||
### D2: PASS @2026-06-15T05:54:37Z
|
||||
Cold run:
|
||||
```
|
||||
tokenize("1+2*3") → ['NUMBER','PLUS','NUMBER','STAR','NUMBER','EOF'] ✓
|
||||
tokenize("+-*/()") → ['PLUS','MINUS','STAR','SLASH','LPAREN','RPAREN','EOF'] ✓
|
||||
```
|
||||
All 6 operator/paren kinds correct. CONFIRMED.
|
||||
|
||||
### D3: PASS @2026-06-15T05:54:37Z
|
||||
Cold run:
|
||||
```
|
||||
tokenize(" 12 + 3 ") → ['NUMBER','PLUS','NUMBER','EOF'] — spaces ✓
|
||||
tokenize("1\t+\t2") → ['NUMBER','PLUS','NUMBER','EOF'] — tabs ✓
|
||||
tokenize("3.5*(1-2)") → [('NUMBER',3.5),('STAR','*'),('LPAREN','('),
|
||||
('NUMBER',1),('MINUS','-'),('NUMBER',2),
|
||||
('RPAREN',')'),('EOF',None)] ✓
|
||||
tokenize("1 @ 2") → LexError: unexpected character '@' at position 2 ✓
|
||||
tokenize("$") → LexError: unexpected character '$' at position 0 ✓
|
||||
tokenize("abc") → LexError: unexpected character 'a' at position 0 ✓
|
||||
```
|
||||
Plan's three mandatory checks (" 12 + 3 ", "3.5*(1-2)", "1 @ 2") all verified. CONFIRMED.
|
||||
|
||||
Advisory finding (non-DoD-blocking): `tokenize("1.2.3")` raises bare `ValueError`
|
||||
(could not convert string to float: '1.2.3') instead of `LexError`. The greedy
|
||||
dot-consuming loop creates raw string "1.2.3" then `float()` crashes. The DoD
|
||||
explicitly only requires LexError for character-level invalids (@, $, letters), so
|
||||
this does NOT block any gate — but noted for the parser phase which may want guarded input.
|
||||
|
||||
### D4: PASS @2026-06-15T05:54:37Z
|
||||
Cold run:
|
||||
```
|
||||
python -m unittest -q
|
||||

|
||||
OK
|
||||
```
|
||||
0 failures, 0 errors. All 13 tests covering D1–D3 (including plan-required cases) pass. CONFIRMED.

|
||||
# -> BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))
|
||||
```
|
||||
Grammar: `_expr` calls `_term` (mul/div) which binds tighter than add/sub. Confirmed with `5-2*3`, `4+6/2`, `1*2+3*4`, `6-2/2`. All correct.
|
||||
|
||||
### parse/D2: PASS @ 2026-06-15T05:59:19Z
|
||||
Cold-run:
|

8-3-2 -> BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))
|
||||
8/4/2 -> BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))
|
||||
```
|
||||
While-loop in `_expr` and `_term` implements left-fold correctly. Also verified `1+2+3`, `6/2*3`. All correct.
|

|
||||
### parse/D3: PASS @ 2026-06-15T05:59:19Z
|
||||
Cold-run:
|
||||
```
|
||||
(1+2)*3 -> BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))
|
||||
```
|
||||
`_primary` handles `(expr)` via recursive `_expr()` + `_consume('RPAREN')`. Also checked `((3))` -> `Num(3)`. Correct.
|
||||
|
||||
### parse/D4: PASS @ 2026-06-15T05:59:19Z
|
||||
Cold-run:
|
||||
```
|
||||
-5 -> Unary('-', Num(5))
|
||||
-(1+2) -> Unary('-', BinOp('+', Num(1), Num(2)))
|
||||
3 * -2 -> BinOp('*', Num(3), Unary('-', Num(2)))
|
||||
```
|
||||
Also probed: `--5` -> `Unary('-', Unary('-', Num(5)))` (recursive unary), `-1+2` -> `BinOp('+', Unary('-', Num(1)), Num(2))`, `1+-2` -> `BinOp('+', Num(1), Unary('-', Num(2)))`. All correct.
|
||||
|
||||
### parse/D5: PASS @ 2026-06-15T05:59:19Z
|
||||
Cold-run for all 5 specified cases (`'1 +'`, `'(1'`, `'1 2'`, `')('`, `''`): all raise `ParseError`, no other exceptions.
|
||||
Extended probes: `+`, `*1`, `1*`, `)(`, `1++2`, `((`, `1 2 3`, `()`, ` ` all raise `ParseError`. No `ValueError`/`IndexError`/etc. found.
|
||||
|
||||
### parse/D6: PASS @ 2026-06-15T05:59:19Z
|
||||
Cold-run:
|
||||
```
|

||||
---
|
||||
|
||||
## Gate D2 — division CLAIMED
|
||||
|
||||
**WHAT:** `/` is true division (`"7/2"`→3.5). Division by zero raises `EvalError` — not bare `ZeroDivisionError`.
|
||||
|
||||
**HOW:**

||||
```
|
||||
3 tests, 0 failures, exit 0.
|
||||

|
||||
|
||||
---
|
||||
|
||||
## Gate D3 — result type CLAIMED
|
||||
|
||||
**WHAT:** Whole-valued floats print without `.0` (`"4/2"`→`2`); non-whole print as float (`"7/2"`→`3.5`). Rule is in `format_result()` in `calc/evaluator.py`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest calc.test_evaluator.TestD3ResultType -v
|
||||
# And manually:
|
||||
python calc.py "4/2" # expect: 2

test_format_nonwhole_float ... ok
|

**WHAT:** `python calc.py "2+3*4"` prints `14`, exits 0. `python calc.py "1 +"` prints error to stderr, exits non-zero (no traceback).
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest calc.test_evaluator.TestD4CLI -v
|
||||
# Manual spot-checks:
|
||||
python calc.py "2+3*4" # stdout: 14, exit 0
|
||||
python calc.py "1 +" # stderr: error:..., exit 1, stdout empty
|
||||
python calc.py "1/0" # stderr: error:..., exit 1
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
test_div_by_zero_exits_nonzero ... ok
|
||||

```
|

## Gate D5 — tests green + end-to-end CLAIMED
|
||||
|
||||
**WHAT:** `calc/test_evaluator.py` passes covering D1–D3+D4; whole prior suite (lex+parse) still passes; no regression.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest -q
|
||||
# Full end-to-end plan verify:
|
||||
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:**
|
||||
```
|
||||
Ran 50 tests in ~0.2s
|
||||
|
||||
OK
|
||||
```
|
||||
Exit 0. 50 tests total: 19 lex + 12 parse + 19 evaluator (5 D1 + 3 D2 + 5 D3 + 6 D4).
|
||||
|
||||

## AST Shape (for Adversary reference)
|

Nodes (from `calc/parser.py`):
|

- `Num(value)` — a number literal
|

- `BinOp(op, left, right)` — binary operation; op in {'+', '-', '*', '/'}
|
||||
- `Unary(op, operand)` — unary minus; op == '-'
|
||||
- `ParseError` — raised on malformed input
|

## Gates
|

|
||||
### D1 — Precedence CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** `*` and `/` bind tighter than `+` and `-`.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('1+2*3'))))"
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))
|
||||
```
|
||||
|
||||
### D2 — Left Associativity CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** Same-precedence operators associate left.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('8-3-2'))))"
|
||||
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(3)), Num(2))
|
||||
BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))
|
||||
```
|
||||
|
||||
### D3 — Parentheses CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** Parens override precedence.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
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 CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** Leading and nested unary minus parses correctly.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('-5'))))"
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('-(1+2)'))))"
|
||||
python -c "from calc.lexer import tokenize; from calc.parser import parse; print(repr(parse(tokenize('3 * -2'))))"
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
Unary('-', Num(5))
|
||||
Unary('-', BinOp('+', Num(1), Num(2)))
|
||||
BinOp('*', Num(3), Unary('-', Num(2)))
|
||||
```
|
||||
|
||||
### D5 — Errors CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** 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(f'NO ERROR for {src!r} — BUG')
|
||||
except ParseError as e:
|
||||
print(f'OK ParseError for {src!r}')
|
||||
except Exception as e:
|
||||
print(f'WRONG exception {type(e).__name__} for {src!r}')
|
||||
"
|
||||
```
|
||||
|
||||
**EXPECTED:** Each case prints `OK ParseError for ...`
|
||||
|
||||
### D6 — Tests Green CLAIMED, awaiting Adversary
|
||||
|
||||
**WHAT:** `calc/test_parser.py` passes under `python -m unittest`, 0 failures.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest -q
|
||||
```
|
||||
|
||||
**EXPECTED:**
|
||||
```
|
||||
Ran 31 tests in <time>
|
||||
|
||||
OK
|
||||
