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):

Exactly. In `cfg1`, the terminal `"TER:A"` is being parsed as a `Variable` named `"A"`. The documentation says `TER:X` should be a terminal. Let's look at `CFG.from_text` implementation. It's likely using some helper in `pyformlang/cfg/cfg.py` or `pyformlang/cfg/utils_cfg.py`.

Look at `_read_line` implementation (lines 1072-1100 in `cfg.py`):
```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))
```
The issue is here:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
# ...
```
If `type_component` is `"TER"`, but `body_component[0]` is uppercase, it will still be treated as a `Variable` because the first condition `body_component[0] in string.ascii_uppercase` is checked first.
It should probably be:
If `type_component == "VAR"`, it's a Variable.
Else if `type_component == "TER"`, it's a Terminal.
Else if `body_component[0]` is uppercase, it's a Variable.
Else, it's a Terminal (unless it's in EPSILON_SYMBOLS).
Wait, let's look at the `elif` part:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
This `elif` also looks suspicious. `body_component not in EPSILON_SYMBOLS or type_component == "TER"`. If `body_component` is in `EPSILON_SYMBOLS`, it will still be a Terminal if `type_component == "TER"`. But if it's not in `EPSILON_SYMBOLS`, it's ALWAYS a Terminal according to this `elif`.
Actually, the logic should be:
1. If `type_component == "VAR"`, then it's a `Variable`.
2. Else if `type_component == "TER"`, then it's a `Terminal`.
3. Else if `body_component[0]` is uppercase, then it's a `Variable`.
4. Else if `body_component` is in `EPSILON_SYMBOLS`, then it's an `Epsilon` (implied, though `Production` handles `Epsilon` filtering by default in `__init__`). Let's see how `Epsilon` is handled.
Wait, `Production.__init__` does:
```python
def __init__(self, head: Variable, body: List[CFGObject], filtering=True):
if filtering:
self._body = [x for x in body if not isinstance(x, Epsilon)]
else:
self._body = body
```
So if we add an `Epsilon` object to the body, it will be filtered out.
Let's see where `EPSILON_SYMBOLS` comes from. It's probably in `pyformlang/cfg/cfg.py` or `pyformlang/cfg/utils_cfg.py`. Let me check `cfg.py` again or search for it.

Look at `_read_line` implementation (lines 1072-1100 in `cfg.py`):
```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))
```
The issue is here:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
body_var = Variable(body_component)
# ...
```
If `type_component` is `"TER"`, but `body_component[0]` is uppercase, it will still be treated as a `Variable` because the first condition `body_component[0] in string.ascii_uppercase` is checked first.
It should probably be:
If `type_component == "VAR"`, it's a Variable.
Else if `type_component == "TER"`, it's a Terminal.
Else if `body_component[0]` is uppercase, it's a Variable.
Else, it's a Terminal (unless it's in EPSILON_SYMBOLS).
Wait, let's look at the `elif` part:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
This `elif` also looks suspicious. `body_component not in EPSILON_SYMBOLS or type_component == "TER"`. If `body_component` is in `EPSILON_SYMBOLS`, it will still be a Terminal if `type_component == "TER"`. But if it's not in `EPSILON_SYMBOLS`, it's ALWAYS a Terminal according to this `elif`.
Actually, the logic should be:
1. If `type_component == "VAR"`, then it's a `Variable`.
2. Else if `type_component == "TER"`, then it's a `Terminal`.
3. Else if `body_component[0]` is uppercase, then it's a `Variable`.
4. Else if `body_component` is in `EPSILON_SYMBOLS`, then it's an `Epsilon` (implied, though `Production` handles `Epsilon` filtering by default in `__init__`). Let's see how `Epsilon` is handled.
Wait, `Production.__init__` does:
```python
def __init__(self, head: Variable, body: List[CFGObject], filtering=True):
if filtering:
self._body = [x for x in body if not isinstance(x, Epsilon)]
else:
self._body = body
```
So if we add an `Epsilon` object to the body, it will be filtered out.
Let's see where `EPSILON_SYMBOLS` comes from. It's probably in `pyformlang/cfg/cfg.py` or `pyformlang/cfg/utils_cfg.py`. Let me check `cfg.py` again or search for it.

Okay, so `is_special_text` checks for `"VAR:...` or `"TER:...`.
Now let's fix `_read_line` in `pyformlang/cfg/cfg.py`.
Current logic:
```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)
```
This is definitely wrong for `TER:A`. `body_component` is `A`, `type_component` is `TER`.
`body_component[0]` is `A`, which is in `string.ascii_uppercase`. So it goes into the `if` and becomes a `Variable`.
Correct logic should prioritize `type_component` if it's set.
```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)
else:
# It's an epsilon symbol
from .epsilon import Epsilon
body.append(Epsilon())
```
Wait, let's check how epsilon was handled. In the original code:
```python
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` is in `EPSILON_SYMBOLS` AND `type_component` is not `"TER"`, it doesn't enter the `elif`. In that case, nothing is appended to `body`. This is equivalent to omitting a token or treating it as epsilon. Since `Production` filters out `Epsilon` objects, this might be the intended behavior. But `Epsilon` is a class in `pyformlang.cfg.epsilon`.
Let's see if there are other places where epsilons are handled in `_read_line`.
Actually, if `body_component` is an epsilon symbol and `type_component` is not `"TER"`, it just doesn't add anything to `body`.
Let's double check the original logic 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` is "epsilon", `type_component` is "".
Is "epsilon"[0] in `ascii_uppercase`? No.
Is "epsilon" not in `EPSILON_SYMBOLS`? No.
Is `type_component == "TER"`? No.
So "epsilon" is ignored.
If `body_component` is "A", `type_component` is "".
Is "A"[0] in `ascii_uppercase`? Yes.
So "A" becomes a `Variable`.
If `body_component` is "a", `type_component` is "".
Is "a"[0] in `ascii_uppercase`? No.
Is "a" not in `EPSILON_SYMBOLS`? Yes.
So "a" becomes a `Terminal`.
If `body_component` is "A", `type_component` is "TER".
Is "A"[0] in `ascii_uppercase`? Yes.
So "A" becomes a `Variable`. <--- BUG!
So we should check `type_component` first.
```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 if `body_component` is empty? `body_component[0]` would raise an `IndexError`.
Is it possible for `body_component` to be empty?
`for body_component in sub_body.split():`
`split()` without arguments removes all whitespace and doesn't return empty strings. So `body_component` will always have at least one character.
Let's re-verify the proposed logic.
1. `type_component == "VAR"` -> Variable (Correct)
2. `type_component == "TER"` -> Terminal (Correct, even if uppercase)
3. `body_component[0]` is uppercase -> Variable (Correct, if no explicit type)
4. `body_component` not in `EPSILON_SYMBOLS` -> Terminal (Correct)
5. Otherwise -> Epsilon (Ignored, as in the original code)
Wait, what if it's `TER:epsilon`?
`type_component == "TER"` will be true, so it will be a `Terminal("epsilon")`. This matches the original `elif body_component not in EPSILON_SYMBOLS or type_component == "TER":`.
So the proposed change is:
```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 can make it more concise if I want to keep it close to original:
```python
if type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS and body_component[0] not in string.ascii_uppercase):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
elif 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)
```
Actually, the `if/elif/elif/elif` chain is clearer.
Let's check the head part too.
```python
head_text = head_s.strip()
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
variables.add(head)
```
`is_special_text` checks for `"VAR:` or `"TER:`.
If `head_text` is `"TER:A"`, `head_text` becomes `A`, and then `head = Variable(A)`.
Is this correct? CFG head must always be a `Variable`.
So `"TER:A"` as head should probably still be a `Variable` "A".
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"".
For the head, it only needs to handle "VAR:". If "TER:" is given for the head, it's slightly weird but still needs to be a `Variable`.
Wait, let's look at `is_special_text` again.
```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] == '"'
```
It supports both `"VAR:` and `"TER:`.
If `head_text` is `"VAR:a"`, `head_text` becomes `a`, and `head = Variable("a")`. Correct.
If `head_text` is `"TER:A"`, `head_text` becomes `A`, and `head = Variable("A")`. Correct, because head is always a Variable.
Now let's implement the fix for the body.
Wait, maybe I should use the same logic for the head too, just in case? No, for the head it's always a `Variable`.
Let's refine the `_read_line` fix.
```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)
```
One thing to notice: the original code used `string.ascii_uppercase`. I need to make sure `string` is imported in `cfg.py`.

Wait, I should check if there are any other places where this logic is used.
`_read_line` is a class method of `CFG`. Let's see if other classes use similar logic or if there are other `from_text` methods.
`CFG.from_text` is the only one.
Wait, let's check `pyformlang/fcfg/fcfg.py` as well, as it might also have a `from_text` method.
