You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

You are evaluating a software engineering task for repository Aunsiels/pyformlang.
Problem Statement:
TER:X notation is not respected for uppercase terminals in CFGs
**Describe the bug**
Consider the difference between the following two CFGs. According to the `from_text` documentation, they should be equivalent.
```
from pyformlang.cfg import CFG, Production, Terminal, Variable
cfg = CFG.from_text('S -> "TER:A"')
print(cfg.is_empty())
print(cfg.productions)
print("vs")
# vs
cfg = CFG(
variables={"S"},
terminals={"A"},
start_symbol="S",
productions={Production(Variable("S"), (Terminal("A"),))},
)
print(cfg.is_empty())
print(cfg.productions)
```
**Expected behavior**
Generating the second CFG when parsing the first text.
## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns
## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.
## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.
## Workspace Layout
The repository is located at `/workspace`. Here is the directory tree (up to 3 levels):

Wait, the output is a bit weird.
`Case 1: from_text` -> `productions: {S -> A}`.
Wait, `S -> A`. Is `A` a Variable or a Terminal here?
Usually in `pyformlang`, if it's uppercase, it's treated as a Variable unless specified otherwise.
The `from_text` documentation (or at least the bug report) implies that `"TER:A"` should be treated as Terminal "A".
In `Case 1`, `cfg1.productions` is `{S -> A}`.
In `Case 2`, `cfg2.productions` is `{S -> Terminal(A)}`.
Actually, `Production(Variable("S"), (Terminal("A"),))` should print as `S -> Terminal(A)` if `Terminal` is represented as such, or `S -> A` if the `__repr__` of `Terminal` is just its value.
Let's check the types of the symbols in `cfg1` and `cfg2`.

Aha!
In `cfg1 = CFG.from_text('S -> "TER:A"')`, the RHS is `[<class 'pyformlang.cfg.variable.Variable'>]`.
So `"TER:A"` was parsed as a `Variable("A")` instead of a `Terminal("A")`.
This confirms the bug: `TER:X` notation is not being respected for uppercase terminals.
Now let's find where `from_text` is implemented. It's likely in `pyformlang/cfg/cfg.py`.

Aha!
In `cfg1 = CFG.from_text('S -> "TER:A"')`, the RHS is `[<class 'pyformlang.cfg.variable.Variable'>]`.
So `"TER:A"` was parsed as a `Variable("A")` instead of a `Terminal("A")`.
This confirms the bug: `TER:X` notation is not being respected for uppercase terminals.
Now let's find where `from_text` is implemented. It's likely in `pyformlang/cfg/cfg.py`.

I found the bug! Look at `_read_line`:
```python
@classmethod
def _read_line(cls, line, productions, terminals, variables):
head_s, body_s = line.split("->")
head_text = head_s.strip()
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
for sub_body in body_s.split("|"):
body = []
for body_component in sub_body.split():
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
else:
type_component = ""
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
productions.add(Production(head, body))
```
Wait, look at this:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component == "TER"`, but `body_component[0]` is in `string.ascii_uppercase`, the first `if` block is entered and it becomes a `Variable`.
If `is_special_text(body_component)` is true, and it is `"TER:A"`, then `type_component` becomes `"TER"` and `body_component` becomes `"A"`.
Since `"A"` is in `string.ascii_uppercase`, it enters the `if` block:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
```
And it is treated as a `Variable`, even though `type_component == "TER"`.
The logic should be:
1. If `type_component == "VAR"`, it's a `Variable`.
2. If `type_component == "TER"`, it's a `Terminal`.
3. If no `type_component`, use the first letter to decide:
- Uppercase -> `Variable`
- Not Uppercase (and not epsilon) -> `Terminal`
- Epsilon -> Epsilon
Wait, let's look closer at the original code:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component` is `"TER"`, we WANT it to be a `Terminal`. But if it also starts with uppercase, the first `if` takes precedence.
The correct logic should prioritize `type_component` if it's set.
Revised logic:
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, what about the `elif body_component not in EPSILON_SYMBOLS or type_component == "TER":`?
If `body_component` IS in `EPSILON_SYMBOLS`, and `type_component` is `"TER"`, it should probably be a `Terminal` of the epsilon symbol's name, not an `Epsilon` object. Actually, `Epsilon` is a special class. If someone does `"TER:epsilon"`, they probably want a terminal that looks like "epsilon".
Let's see how `EPSILON_SYMBOLS` are handled.
If `body_component` is in `EPSILON_SYMBOLS`, and `type_component == ""`, then it fails the first `if` (assuming epsilon symbol is lowercase) and the `elif` (since `body_component not in EPSILON_SYMBOLS` is false, and `type_component == "TER"` is false). So it just doesn't get added to the body?
Wait, `Epsilon` objects are filtered out in `Production.__init__` if `filtering=True`.
Wait, I should check how epsilon is normally added.
Looking at `_read_line` again:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `body_component` equals `"epsilon"` and `type_component` is `""`:
- `body_component[0]` is `'e'`, not uppercase. `type_component` is `""`, not `"VAR"`.
- `body_component not in EPSILON_SYMBOLS` is False. `type_component == "TER"` is False.
Result: nothing is appended to `body`. This is how empty productions (epsilon) are handled in `from_text`.
So if `type_component == "TER"`, we MUST treat it as a `Terminal`, even if it's in `EPSILON_SYMBOLS` or starts with uppercase.
So the logic should be:
1. If `type_component` is present:
- If `"VAR"`, Variable.
- If `"TER"`, Terminal.
2. If `type_component` is NOT present:
- If `body_component[0]` is uppercase, Variable.
- If `body_component` is not in `EPSILON_SYMBOLS`, Terminal.
- Else (it's an epsilon symbol), skip (meaning epsilon production).
Wait, one more thing: `body_component[0]` will raise `IndexError` if `body_component` is an empty string. `sub_body.split()` should prevent that, but let's be careful.
Let's implement this.
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Actually, we can simplify:
```python
if type_component == "VAR" or (not type_component and body_component[0] in string.ascii_uppercase):
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER" or (not type_component and body_component not in EPSILON_SYMBOLS):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Let's double check if `body_component` can be empty. `sub_body.split()` returns a list of non-empty strings.
Wait, look at the original code again.
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component == "TER"` and `body_component[0]` is uppercase, it's a `Variable`. This is the bug.
If `type_component == "VAR"` and `body_component[0]` is NOT uppercase, it's a `Variable`. This is correct.
So the problem is only when `type_component == "TER"` and `body_component[0]` is uppercase.
If we just change the order:
```python
if type_component == "VAR" or \
(type_component == "" and body_component[0] in string.ascii_uppercase):
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER" or \
(type_component == "" and body_component not in EPSILON_SYMBOLS):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
But wait, what if `type_component` is neither `"VAR"` nor `"TER"`? The `is_special_text` function only returns true if it starts with `"VAR:` or `"TER:`.
```python
def is_special_text(text):
""" Check if the input is given an explicit type """
return len(text) > 5 and \
(text[0:5] == '"VAR:' or text[0:5] == '"TER:') and \
text[-1] == '"'
```
Wait, `text[0:5]` for `"VAR:A"`...
`"VAR:A"`: indices 0 1 2 3 4.
`text[0:5]` is `"VAR:A"` if the string is `"VAR:A"`.
But look at the code: `(text[0:5] == '"VAR:' or text[0:5] == '"TER:')`.
The first character is a double quote.
So `"VAR:A"` would be `'"VAR:A"'`.
`text[0:5]` would be `'"VAR:'`.
This is correct.
Then:
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
```
If `body_component` is `'"TER:A"'`:
`type_component = body_component[1:4]` -> `body_component[1]` is `T`, `[2]` is `E`, `[3]` is `R`. So `type_component` is `"TER"`.
`body_component = body_component[5:-1]` -> from index 5 to before the last char.
`'"TER:A"'`
012345
`"` `T` `E` `R` `:` `A` `"`
Index 5 is `A`. Last char is `"`. So `body_component` becomes `"A"`.
This is correct.
So the fix is indeed to prioritize `type_component`.
Let's try to implement it. I'll use the more explicit version for clarity.
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, I should also check if this affects any other case.
Case 1: `body_component` is `"S"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'S'` (T) -> Variable. Correct.
Case 2: `body_component` is `"a"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'a'` (F)
- `body_component` is not in `EPSILON_SYMBOLS` (T) -> Terminal. Correct.
Case 3: `body_component` is `"epsilon"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'e'` (F)
- `body_component` is not in `EPSILON_SYMBOLS` (F) -> Skip. Correct.
Case 4: `body_component` is `'"TER:A"'`. `type_component` is `"TER"`, `body_component` is `"A"`.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (T) -> Terminal. Correct! (Before it was Variable)
Case 5: `body_component` is `'"VAR:a"'`. `type_component` is `"VAR"`, `body_component` is `"a"`.
- `type_component == "VAR"` (T) -> Variable. Correct! (Before it was Terminal)
Case 6: `body_component` is `'"TER:epsilon"'`. `type_component` is `"TER"`, `body_component` is `"epsilon"`.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (T) -> Terminal. Correct!
Case 7: `body_component` is `'"VAR:S"'`. `type_component` is `"VAR"`, `body_component` is `"S"`.
- `type_component == "VAR"` (T) -> Variable. Correct.
This logic seems robust.
Wait, I should check the `head` as well.
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
```
The head is always a `Variable` in a CFG. If it's `"TER:S"`, it should still be a `Variable("S")`.
Actually, the documentation says:
`If you want to have a variable name starting with a non-capital letter or a terminal starting with a capital letter, you can explicitly give the type of your symbol with "VAR:yourVariableName" or "TER:yourTerminalName" (with the quotation marks).`
Wait, does this apply to the head too?
If `head_text` is `'"TER:A"'`, then `is_special_text` is true, and `head_text` becomes `"A"`. Then it's wrapped in `Variable("A")`.
Is this what's intended?
Usually, the left hand side of a production in CFG MUST be a variable.
If the user writes `'"TER:A"' -> 'b'`, they might be trying to create something that's not a CFG, but the class is `CFG`.
The current code:
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
```
It always makes the head a `Variable`. This seems correct for a `CF

I found the bug! Look at `_read_line`:
```python
@classmethod
def _read_line(cls, line, productions, terminals, variables):
head_s, body_s = line.split("->")
head_text = head_s.strip()
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
for sub_body in body_s.split("|"):
body = []
for body_component in sub_body.split():
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
else:
type_component = ""
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
productions.add(Production(head, body))
```
Wait, look at this:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component == "TER"`, but `body_component[0]` is in `string.ascii_uppercase`, the first `if` block is entered and it becomes a `Variable`.
If `is_special_text(body_component)` is true, and it is `"TER:A"`, then `type_component` becomes `"TER"` and `body_component` becomes `"A"`.
Since `"A"` is in `string.ascii_uppercase`, it enters the `if` block:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
```
And it is treated as a `Variable`, even though `type_component == "TER"`.
The logic should be:
1. If `type_component == "VAR"`, it's a `Variable`.
2. If `type_component == "TER"`, it's a `Terminal`.
3. If no `type_component`, use the first letter to decide:
- Uppercase -> `Variable`
- Not Uppercase (and not epsilon) -> `Terminal`
- Epsilon -> Epsilon
Wait, let's look closer at the original code:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component` is `"TER"`, we WANT it to be a `Terminal`. But if it also starts with uppercase, the first `if` takes precedence.
The correct logic should prioritize `type_component` if it's set.
Revised logic:
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, what about the `elif body_component not in EPSILON_SYMBOLS or type_component == "TER":`?
If `body_component` IS in `EPSILON_SYMBOLS`, and `type_component` is `"TER"`, it should probably be a `Terminal` of the epsilon symbol's name, not an `Epsilon` object. Actually, `Epsilon` is a special class. If someone does `"TER:epsilon"`, they probably want a terminal that looks like "epsilon".
Let's see how `EPSILON_SYMBOLS` are handled.
If `body_component` is in `EPSILON_SYMBOLS`, and `type_component == ""`, then it fails the first `if` (assuming epsilon symbol is lowercase) and the `elif` (since `body_component not in EPSILON_SYMBOLS` is false, and `type_component == "TER"` is false). So it just doesn't get added to the body?
Wait, `Epsilon` objects are filtered out in `Production.__init__` if `filtering=True`.
Wait, I should check how epsilon is normally added.
Looking at `_read_line` again:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `body_component` equals `"epsilon"` and `type_component` is `""`:
- `body_component[0]` is `'e'`, not uppercase. `type_component` is `""`, not `"VAR"`.
- `body_component not in EPSILON_SYMBOLS` is False. `type_component == "TER"` is False.
Result: nothing is appended to `body`. This is how empty productions (epsilon) are handled in `from_text`.
So if `type_component == "TER"`, we MUST treat it as a `Terminal`, even if it's in `EPSILON_SYMBOLS` or starts with uppercase.
So the logic should be:
1. If `type_component` is present:
- If `"VAR"`, Variable.
- If `"TER"`, Terminal.
2. If `type_component` is NOT present:
- If `body_component[0]` is uppercase, Variable.
- If `body_component` is not in `EPSILON_SYMBOLS`, Terminal.
- Else (it's an epsilon symbol), skip (meaning epsilon production).
Wait, one more thing: `body_component[0]` will raise `IndexError` if `body_component` is an empty string. `sub_body.split()` should prevent that, but let's be careful.
Let's implement this.
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Actually, we can simplify:
```python
if type_component == "VAR" or (not type_component and body_component[0] in string.ascii_uppercase):
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER" or (not type_component and body_component not in EPSILON_SYMBOLS):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Let's double check if `body_component` can be empty. `sub_body.split()` returns a list of non-empty strings.
Wait, look at the original code again.
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
If `type_component == "TER"` and `body_component[0]` is uppercase, it's a `Variable`. This is the bug.
If `type_component == "VAR"` and `body_component[0]` is NOT uppercase, it's a `Variable`. This is correct.
So the problem is only when `type_component == "TER"` and `body_component[0]` is uppercase.
If we just change the order:
```python
if type_component == "VAR" or \
(type_component == "" and body_component[0] in string.ascii_uppercase):
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER" or \
(type_component == "" and body_component not in EPSILON_SYMBOLS):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
But wait, what if `type_component` is neither `"VAR"` nor `"TER"`? The `is_special_text` function only returns true if it starts with `"VAR:` or `"TER:`.
```python
def is_special_text(text):
""" Check if the input is given an explicit type """
return len(text) > 5 and \
(text[0:5] == '"VAR:' or text[0:5] == '"TER:') and \
text[-1] == '"'
```
Wait, `text[0:5]` for `"VAR:A"`...
`"VAR:A"`: indices 0 1 2 3 4.
`text[0:5]` is `"VAR:A"` if the string is `"VAR:A"`.
But look at the code: `(text[0:5] == '"VAR:' or text[0:5] == '"TER:')`.
The first character is a double quote.
So `"VAR:A"` would be `'"VAR:A"'`.
`text[0:5]` would be `'"VAR:'`.
This is correct.
Then:
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
```
If `body_component` is `'"TER:A"'`:
`type_component = body_component[1:4]` -> `body_component[1]` is `T`, `[2]` is `E`, `[3]` is `R`. So `type_component` is `"TER"`.
`body_component = body_component[5:-1]` -> from index 5 to before the last char.
`'"TER:A"'`
012345
`"` `T` `E` `R` `:` `A` `"`
Index 5 is `A`. Last char is `"`. So `body_component` becomes `"A"`.
This is correct.
So the fix is indeed to prioritize `type_component`.
Let's try to implement it. I'll use the more explicit version for clarity.
```python
if type_component == "VAR":
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif type_component == "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS:
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, I should also check if this affects any other case.
Case 1: `body_component` is `"S"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'S'` (T) -> Variable. Correct.
Case 2: `body_component` is `"a"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'a'` (F)
- `body_component` is not in `EPSILON_SYMBOLS` (T) -> Terminal. Correct.
Case 3: `body_component` is `"epsilon"`, no type.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (F)
- `body_component[0]` is `'e'` (F)
- `body_component` is not in `EPSILON_SYMBOLS` (F) -> Skip. Correct.
Case 4: `body_component` is `'"TER:A"'`. `type_component` is `"TER"`, `body_component` is `"A"`.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (T) -> Terminal. Correct! (Before it was Variable)
Case 5: `body_component` is `'"VAR:a"'`. `type_component` is `"VAR"`, `body_component` is `"a"`.
- `type_component == "VAR"` (T) -> Variable. Correct! (Before it was Terminal)
Case 6: `body_component` is `'"TER:epsilon"'`. `type_component` is `"TER"`, `body_component` is `"epsilon"`.
- `type_component == "VAR"` (F)
- `type_component == "TER"` (T) -> Terminal. Correct!
Case 7: `body_component` is `'"VAR:S"'`. `type_component` is `"VAR"`, `body_component` is `"S"`.
- `type_component == "VAR"` (T) -> Variable. Correct.
This logic seems robust.
Wait, I should check the `head` as well.
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
```
The head is always a `Variable` in a CFG. If it's `"TER:S"`, it should still be a `Variable("S")`.
Actually, the documentation says:
`If you want to have a variable name starting with a non-capital letter or a terminal starting with a capital letter, you can explicitly give the type of your symbol with "VAR:yourVariableName" or "TER:yourTerminalName" (with the quotation marks).`
Wait, does this apply to the head too?
If `head_text` is `'"TER:A"'`, then `is_special_text` is true, and `head_text` becomes `"A"`. Then it's wrapped in `Variable("A")`.
Is this what's intended?
Usually, the left hand side of a production in CFG MUST be a variable.
If the user writes `'"TER:A"' -> 'b'`, they might be trying to create something that's not a CFG, but the class is `CFG`.
The current code:
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
```
It always makes the head a `Variable`. This seems correct for a `CF<channel|><|tool_call>call:edit_file{filepath:<|"|>pyformlang/cfg/cfg.py<|"|>,new_string:<|"|> if type_component == "VAR":
