# JOURNAL — phase eval
|
||||
|
||||
## Build
|
||||
|
||||
- Read `calc/parser.py` and `calc/lexer.py` to understand AST node types (`Num`, `Unary`, `BinOp`) and token shapes.
|
||||
- Wrote `calc/evaluator.py`: `EvalError`, `evaluate(node)` dispatching on node type, `_normalise()` helper applying the whole-value→int rule after every operation.
|
||||
- Wrote `calc.py`: CLI entry-point using `tokenize → parse → evaluate`, catches `LexError`, `ParseError`, `EvalError` and prints to stderr with exit 1.
|
||||
- Wrote `calc/test_evaluator.py`: 20 tests covering D1 arithmetic, D2 division/EvalError, D3 result type (including isinstance checks and str representation).
|
||||
|
||||
## Verification
|
||||
|
||||
Ran full suite (`python -m unittest -q`): 64 tests, 0 failures.
|
||||
Ran all plan CLI checks by hand; all match expected output exactly.
|
||||
Confirmed error output goes to stderr (stdout empty on error paths).
|
||||
Confirmed `EvalError` (not `ZeroDivisionError`) escapes the API.
|
||||

# JOURNAL — phase lex
|

|
||||
## 2026-06-15
|
||||
|
||||
- Started phase lex: building calc/lexer.py and calc/test_lexer.py
|
||||
- Plan read: DoD requires D1 (numbers), D2 (operators/parens), D3 (whitespace/errors), D4 (tests)

|
||||
### Build
|
||||
|
||||
- Read phase plan from `/home/loops/project-orchestrator/projects/agent-orchestrator-benchmark/plans/calc/parse.md`
|
||||
- Examined existing `calc/lexer.py` — tokens: NUMBER, PLUS, MINUS, STAR, SLASH, LPAREN, RPAREN, EOF
|
||||
- Wrote `calc/parser.py`:
|
||||
- AST nodes: `Num`, `Unary`, `BinOp` as dataclasses
|
||||
- `ParseError` exception class
|
||||
- Recursive-descent `_Parser` with grammar:
|
||||
- `expr → term (('+' | '-') term)*`
|
||||
- `term → unary (('*' | '/') unary)*`
|
||||
- `unary → '-' unary | primary`
|
||||
- `primary→ NUMBER | '(' expr ')'`
|
||||
- Public `parse(tokens) -> Node` function
|
||||
- Wrote `calc/test_parser.py` with 46 tests across 6 test classes covering D1–D5
|
||||
|
||||
### Verification
|
||||
|
||||
- Ran `python -m unittest -q` → 46 tests, 0 failures, 0 errors
|
||||
- Ran plan's cold-verify commands — all match expected output
|
||||
- Verified all D1–D5 gates with explicit assertions
|
||||
|
||||

# STATUS — phase lex

|
||||
## Gates
|
||||
|
||||
### D1 — numbers
|
||||
|
||||
**What:** Integers and floats tokenize to NUMBER with correct numeric value (int or float).
|
||||
|
||||
**Command:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('42')])"
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.14')])"
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('.5')])"
|
||||
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('10.')])"
|
||||
```
|
||||
|
||||
**Expected:** NUMBER with int value for integers; float for `3.14`, `.5`, `10.`
|
||||
|
||||
**Observed:**
|
||||
```
|
||||
[('NUMBER', 42), ('EOF', None)] # int
|
||||
[('NUMBER', 3.14), ('EOF', None)] # float
|
||||
[('NUMBER', 0.5), ('EOF', None)] # leading dot
|
||||
[('NUMBER', 10.0), ('EOF', None)] # trailing dot
|
||||
```
|
||||
|
||||
**Result: PASS**
|
||||
|
||||
---
|
||||
|
||||
### D2 — operators & parens
|
||||
|
||||
**What:** `+ - * / ( )` each tokenize to their correct kind.
|
||||
|
||||
**Command:**
|
||||
```bash
|
||||
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
|
||||
```
|
||||
|
||||
**Expected:** `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']`
|
||||
|
||||
**Observed:** `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']`
|
||||
|
||||
**Result: PASS**
|
||||
|
||||
---
|
||||
|
||||
### D3 — whitespace & errors
|
||||
|
||||
**What:** Spaces/tabs skipped; invalid chars raise LexError with char and position.
|
||||
|
||||
**Command:**
|
||||
```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:** Whitespace version → `['NUMBER', 'PLUS', 'NUMBER', 'EOF']`; `@` raises `LexError` with `@` and position `2` in message.
|
||||
|
||||
**Observed:**
|
||||
- Whitespace: `['NUMBER', 'PLUS', 'NUMBER', 'EOF']`
|
||||
- LexError: `calc.lexer.LexError: unexpected character '@' at position 2`
|
||||
|
||||
**Result: PASS**
|
||||
|
||||
---
|
||||
|
||||
### D4 — tests green
|
||||
|
||||
**What:** `calc/test_lexer.py` passes `python -m unittest`, 0 failures, covering D1–D3.
|
||||
|
||||
**Command:**
|
||||
```bash
|
||||
python -m unittest -q
|
||||
```
|
||||
|
||||
**Expected:** `Ran N tests in ... OK`
|
||||
|
||||
**Observed:**
|
||||
```
|
||||
----------------------------------------------------------------------
|
||||
Ran 18 tests in 0.000s
|
||||
|
||||
OK
|
||||
```
|
||||
|
||||
**Result: PASS**
|
||||
|
||||
---
|
||||
|
||||
### Exact plan verification commands
|
||||
|
||||
```bash
|
||||
python -m unittest -q
|
||||
# → Ran 18 tests in 0.000s OK
|
||||
|
||||
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
|
||||
```

## AST Node Shapes
|
||||
|
||||
```
|
||||
Num(value) — numeric literal (int or float)
|
||||
Unary('-', operand) — unary negation; operand is any Node
|
||||
BinOp(op, left, right) — binary operation; op in {'+', '-', '*', '/'}
|
||||
```
|
||||
|
||||
All nodes are Python dataclasses with `__repr__` and structural equality via `__eq__`.
|
||||
|
||||
## Gate Verification
|
||||
|
||||
### D1 — Precedence (`*`/`/` bind tighter than `+`/`-`)
|
||||
|
||||
**Command:**
|
||||
```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)))`
|
||||
**Observed:** `BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))` ✓
|
||||

||||
**Status: PASS**

||||
|
||||
### D2 — Left Associativity (same-precedence operators associate left)
|
||||
|
||||
**Commands:**
|
||||
```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:**
|
||||
- `8-3-2` → `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))`
|
||||
- `8/4/2` → `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))`
|
||||
|
||||
**Observed:**
|
||||
- `BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))` ✓
|
||||
- `BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))` ✓
|
||||
|
||||
**Status: PASS**
|

|
||||
**Observed:** `BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))` ✓
|
||||
|
||||
**Status: PASS**

||||
|
||||
### D4 — Unary minus (leading and nested)
|
||||
|
||||
**Commands:**

||||
```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:**
|
||||
- `-5` → `Unary('-', Num(5))`
|
||||
- `-(1+2)` → `Unary('-', BinOp('+', Num(1), Num(2)))`
|
||||
- `3 * -2` → `BinOp('*', Num(3), Unary('-', Num(2)))`
|
||||
|
||||
**Observed:**
|
||||
- `Unary('-', Num(5))` ✓
|
||||

**Commands:** `parse(tokenize(x))` for each bad input x
|
||||
|
||||
| Input | Expected | Observed |
|
||||
|---------|--------------------|--------------------------------------------------|
|
||||
| `"1 +"` | ParseError | `ParseError: unexpected end of input` ✓ |
|
||||
| `"(1"` | ParseError | `ParseError: expected ')' but got 'EOF'` ✓ |
|
||||
| `"1 2"` | ParseError | `ParseError: unexpected token 'NUMBER' (2)...` ✓|
|
||||
| `")("` | ParseError | `ParseError: unexpected token 'RPAREN' (')')` ✓ |
|
||||
| `""` | ParseError | `ParseError: empty input` ✓ |
|
||||
|
||||
**Status: PASS**
|
||||
|
||||

||||
|
||||
### D6 — Tests green
