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):

The user is reporting a bug in `pyformlang.cfg.CFG.from_text` where the `TER:X` notation is not respected for uppercase terminals in CFGs.
Specifically, `CFG.from_text('S -> "TER:A"')` should produce a CFG with terminal `"A"`, but it seems it is not doing so correctly.
Let's start by reproducing the bug.

Wait, the output is:
`CFG 1: {S -> A}`
`CFG 1 is_empty: True`
`CFG 2: {S -> Terminal(A)}`
`CFG 2 is_empty: False`
`Equal: False`
Wait, if `CFG 1` is `S -> A` and `is_empty` is True, that's weird.
Usually `is_empty` for a CFG might mean something else, or maybe the production is not what I think it is.
Let's look at the output of `cfg1.productions` more closely.
In `CFG 1: {S -> A}`, it seems it thinks `A` is a Variable, not a Terminal.
In `CFG 2: {S -> Terminal(A)}`, it's a Terminal.
Wait, if `A` is a variable in `CFG 1` and it's not the start symbol and there's no production for it, then the language might be empty.
Let's check what `cfg1.variables` and `cfg1.terminals` are.

Yes, `CFG 1` has `Variable(A)` as a variable and no terminals.
So `from_text('S -> "TER:A"')` is treating `"TER:A"` as a variable `A` instead of a terminal `A`.
According to the problem statement, `TER:X` notation should make it a terminal.
Let's find where `CFG.from_text` is implemented. It's probably in `pyformlang/cfg/cfg.py`.

Wait, I see the bug in `_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))
```
If `body_component` is `"TER:A"`, `is_special_text` should be true.
Assuming `is_special_text` checks for quotation marks.
If `is_special_text(body_component)` is true:
`type_component` becomes `"TER"` (indices 1 to 4: `body_component[1:4]`).
`body_component` becomes `"A"` (indices 5 to -1: `body_component[5:-1]`).
Then it checks:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
```
Since `body_component[0]` is `'A'`, which is in `string.ascii_uppercase`, it enters the `if` block and creates a `Variable("A")`.
It should only create a `Variable` if it's either NOT special and starts with uppercase, OR it's special and `type_component == "VAR"`.
If it's special, `type_component` should decide whether it's a `Variable` or `Terminal`, regardless of the first character of `body_component`.
Correct logic should be:
If it's special, check `type_component`.
If it's not special, check first character.
Let's see how `is_special_text` is defined. It's probably in the same file or imported.

Yes, `is_special_text` checks for `"VAR:` or `"TER:`.
Now let's refine the logic in `_read_line`.
Current logic:
```python
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)
```
Wait, there's also this:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
```
Wait, `body_component not in EPSILON_SYMBOLS` is almost always true if it's a regular character.
If `body_component` is `"A"` and `type_component` is `"TER"`, it still went into the first `if` block because `body_component[0]` is uppercase.
If we are in the `is_special_text` case, we should only care about `type_component`.
Revised logic:
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
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)
else:
if body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.all.add(body_var) # Wait, variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS: # Or whatever the logic for terminals is
...
```
Wait, what if `body_component` is an epsilon symbol?
The original code has:
```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 in `EPSILON_SYMBOLS` and it's not special, it doesn't enter either block.
Wait, if it's not special:
- Starts with Uppercase -> Variable
- Not in `EPSILON_SYMBOLS` -> Terminal
- In `EPSILON_SYMBOLS` -> কিছুই না (nothing)? That's probably how epsilon is handled (it's just not added to the body).
Let's check `EPSILON_SYMBOLS`. It's probably defined earlier in the file.

}Turn 8at 270 s2,073 tokens out9,062 prompt tokens
So if it's `"epsilon"`, it's skipped.
Let's look at the original logic again.
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
```
This is the problem. If `type_component == "TER"` and `body_component[0]` is uppercase, it's treated as a `Variable`.
We should change it to:
If `type_component` is not empty (i.e., it was special), use `type_component` to decide.
Otherwise, use the first character.
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
else:
type_component = ""
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)
```
Wait, what if `body_component` is an empty string? `body_component[0]` would fail.
But `body_component` comes from `sub_body.split()`, so it should not be empty.
Let's check if `type_component == "TER"` is enough when it's special.
If `type_component == "TER"`, it should be a Terminal even if it starts with an uppercase letter.
Let's review the original code's logic for `type_component == "TER"` again.
```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` is only reached if the first `if` is False.
The first `if` is: `body_component[0] in string.ascii_uppercase or type_component == "VAR"`.
So if `body_component[0]` is uppercase, it always goes into the first `if`, regardless of whether `type_component == "TER"`.
So the fix should be:
If `type_component == "VAR"`, it's a Variable.
Else if `type_component == "TER"`, it's a Terminal.
Else (it's not special):
If `body_component[0]` is uppercase, it's a Variable.
Else if `body_component` is not an epsilon symbol, it's a Terminal.
Wait, we also need to check if it's an epsilon symbol before accessing `body_component[0]`.
Wait, if it's not special, it can be an epsilon symbol.
If it's an epsilon symbol, it probably shouldn't be a variable or terminal.
Let's see:
`EPSILON_SYMBOLS = ["epsilon", "$", "ε", "ϵ", "Є"]`
None of these start with uppercase ASCII letters (except maybe some if they were different, but these are all lowercase or symbols).
Wait, let's check `string.ascii_uppercase`.
So if `type_component == "":`
if `body_component[0]` in `string.ascii_uppercase`: it's a `Variable`.
else if `body_component` in `EPSILON_SYMBOLS`: it's an epsilon (do nothing).
else: it's a `Terminal`.
This matches the original intention.
So let's refine the `_read_line` method.
```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 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)
productions.add(Production(head, body))
```
Let's double check the boundaries.
If `body_component` is `"TER:A"`, `is_special_text` is True, `type_component` is `"TER"`, `body_component` is `"A"`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False because `type_component` is not `""`.
`type_component == "TER"` is True. It becomes a `Terminal("A")`. Correct.
If `body_component` is `"A"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is True. It becomes a `Variable("A")`. Correct.
If `body_component` is `"a"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False.
`type_component == "TER"` is False.
`(type_component == "" and body_component not in EPSILON_SYMBOLS)` is True. It becomes a `Terminal("a")`. Correct.
If `body_component` is `"epsilon"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False.
`type_component == "TER"` is False.
`(type_component == "" and body_component not in EPSILON_SYMBOLS)` is False.
It is skipped. Correct.
Wait, let's check if `head_text` also has a bug.
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
```
Head is always a `Variable`. The problem statement only mentioned terminals in the body.
Wait, the `from_text` doc 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)."
It says "give the type of your symbol", and then gives an example `S -> "TER:John" "VAR:d" a b`.
It doesn't explicitly say if the head can be `"VAR:S"`.
In `_read_line`:
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
```
If `head_text` was `"VAR:S"`, `head_text` becomes `"S"`, and `head` becomes `Variable("S")`.
If `head_text` was `"TER:S"`, `head_text` becomes `"S"`, and `head` becomes `Variable("S")`.
But the head must be a Variable in CFG. So this seems okay.
Now let's implement the fix. I'll use `edit_file`.
Wait, I should check if I need to import `string` in `pyformlang/cfg/cfg.py`.
The current code uses `string.ascii_uppercase`. Let's check if `string` is imported.
TOOL CALL · run_command

Yes, it is.
Let's prepare the `edit_file` call.
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)
```
New code:
```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)
```
Wait, the original `elif` was:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
```
If `type_component == "TER"`, it would be a terminal.
If `body_component` was not in `EPSILON_SYMBOLS`, it would be a terminal.
But this was only reached if it didn't start with uppercase AND `type_component` was not `"VAR"`.
My proposed change:
```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)
```
This seems correct and covers all cases.
Let's apply the fix.

I have successfully fixed the bug where `TER:X` notation was not respected for uppercase terminals in CFGs. The fix involved modifying `CFG._read_line` to prioritize the explicit type (`VAR:` or `TER:`) over the leading character of the symbol when determining if it is a variable or a terminal. I verified the fix with the reproduction case and several edge cases, and also ran the existing tests.
Turn 15at 379 s
The bug was caused by `CFG._read_line` prioritizing the leading character of a symbol (uppercase for variables) over its explicitly declared type (`TER:` or `VAR:`). I modified the logic to correctly prioritize the explicit type when present, ensuring that symbols marked with `"TER:X"` are treated as terminals even if they start with an uppercase letter.

Yes, `CFG 1` has `Variable(A)` as a variable and no terminals.
So `from_text('S -> "TER:A"')` is treating `"TER:A"` as a variable `A` instead of a terminal `A`.
According to the problem statement, `TER:X` notation should make it a terminal.

```
If `body_component` is `"TER:A"`, `is_special_text` should be true.
Assuming `is_special_text` checks for quotation marks.
If `is_special_text(body_component)` is true:
`type_component` becomes `"TER"` (indices 1 to 4: `body_component[1:4]`).
`body_component` becomes `"A"` (indices 5 to -1: `body_component[5:-1]`).
Then it checks:
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
```
Since `body_component[0]` is `'A'`, which is in `string.ascii_uppercase`, it enters the `if` block and creates a `Variable("A")`.
It should only create a `Variable` if it's either NOT special and starts with uppercase, OR it's special and `type_component == "VAR"`.
If it's special, `type_component` should decide whether it's a `Variable` or `Terminal`, regardless of the first character of `body_component`.
Correct logic should be:
If it's special, check `type_component`.
If it's not special, check first character.
Let's see how `is_special_text` is defined. It's probably in the same file or imported.
Wait, I see the bug in `_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 = Variable(head_text)
variables.add(head)
for sub_body in body_s.split("|"):
body = []
for body_component in sub_body.split():

body_component = body_component[5:-1]
else:
type_component = ""
if body_component[0] in string.ascii_uppercase or \

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)

```
If `body_component` is `"TER:A"`, `is_special_text` should be true.
Assuming `is_special_text` checks for quotation marks.
If `is_special_text(body_component)` is true:
`type_component` becomes `"TER"` (indices 1 to 4: `body_component[1:4]`).

Yes, `is_special_text` checks for `"VAR:` or `"TER:`.
Now let's refine the logic in `_read_line`.
Current logic:
```python
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)

elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, there's also this:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
```
Wait, `body_component not in EPSILON_SYMBOLS` is almost always true if it's a regular character.
If `body_component` is `"A"` and `type_component` is `"TER"`, it still went into the first `if` block because `body_component[0]` is uppercase.
If we are in the `is_special_text` case, we should only care about `type_component`.
Revised logic:
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
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)
else:
if body_component[0] in string.ascii_uppercase:
body_var = Variable(body_component)
variables.all.add(body_var) # Wait, variables.add(body_var)
body.append(body_var)
elif body_component not in EPSILON_SYMBOLS: # Or whatever the logic for terminals is
...
```
Wait, what if `body_component` is an epsilon symbol?
The original code has:
```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 in `EPSILON_SYMBOLS` and it's not special, it doesn't enter either block.
Wait, if it's not special:
- Starts with Uppercase -> Variable
- Not in `EPSILON_SYMBOLS` -> Terminal
- In `EPSILON_SYMBOLS` -> কিছুই না (nothing)? That's probably how epsilon is handled (it's just not added to the body).
Let's check `EPSILON_SYMBOLS`. It's probably defined earlier in the file.
Yes, `is_special_text` checks for `"VAR:` or `"TER:`.
Now let's refine the logic in `_read_line`.
Current logic:
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]

Wait, what if `body_component` is an epsilon symbol?

So if it's `"epsilon"`, it's skipped.
Let's look at the original logic again.
```python
if body_component[0] in string.ascii_uppercase or \
type_component == "VAR":
```
This is the problem. If `type_component == "TER"` and `body_component[0]` is uppercase, it's treated as a `Variable`.
We should change it to:
If `type_component` is not empty (i.e., it was special), use `type_component` to decide.
Otherwise, use the first character.
```python
if is_special_text(body_component):
type_component = body_component[1:4]
body_component = body_component[5:-1]
else:
type_component = ""
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)
```
Wait, what if `body_component` is an empty string? `body_component[0]` would fail.
But `body_component` comes from `sub_body.split()`, so it should not be empty.
Let's check if `type_component == "TER"` is enough when it's special.
If `type_component == "TER"`, it should be a Terminal even if it starts with an uppercase letter.
Let's review the original code's logic for `type_component == "TER"` again.
```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` is only reached if the first `if` is False.
The first `if` is: `body_component[0] in string.ascii_uppercase or type_component == "VAR"`.
So if `body_component[0]` is uppercase, it always goes into the first `if`, regardless of whether `type_component == "TER"`.
So the fix should be:
If `type_component == "VAR"`, it's a Variable.
Else if `type_component == "TER"`, it's a Terminal.
Else (it's not special):
If `body_component[0]` is uppercase, it's a Variable.
Else if `body_component` is not an epsilon symbol, it's a Terminal.
Wait, we also need to check if it's an epsilon symbol before accessing `body_component[0]`.
Wait, if it's not special, it can be an epsilon symbol.
If it's an epsilon symbol, it probably shouldn't be a variable or terminal.
Let's see:
`EPSILON_SYMBOLS = ["epsilon", "$", "ε", "ϵ", "Є"]`
None of these start with uppercase ASCII letters (except maybe some if they were different, but these are all lowercase or symbols).
Wait, let's check `string.ascii_uppercase`.
So if `type_component == "":`
if `body_component[0]` in `string.ascii_uppercase`: it's a `Variable`.
else if `body_component` in `EPSILON_SYMBOLS`: it's an epsilon (do nothing).
else: it's a `Terminal`.
This matches the original intention.
So let's refine the `_read_line` method.
```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 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)
productions.add(Production(head, body))
```
Let's double check the boundaries.
If `body_component` is `"TER:A"`, `is_special_text` is True, `type_component` is `"TER"`, `body_component` is `"A"`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False because `type_component` is not `""`.
`type_component == "TER"` is True. It becomes a `Terminal("A")`. Correct.
If `body_component` is `"A"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is True. It becomes a `Variable("A")`. Correct.
If `body_component` is `"a"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False.
`type_component == "TER"` is False.
`(type_component == "" and body_component not in EPSILON_SYMBOLS)` is True. It becomes a `Terminal("a")`. Correct.
If `body_component` is `"epsilon"`, `is_special_text` is False, `type_component` is `""`.
`type_component == "VAR"` is False.
`(type_component == "" and body_component[0] in string.ascii_uppercase)` is False.
`type_component == "TER"` is False.
`(type_component == "" and body_component not in EPSILON_SYMBOLS)` is False.
It is skipped. Correct.
Wait, let's check if `head_text` also has a bug.
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
```
Head is always a `Variable`. The problem statement only mentioned terminals in the body.
Wait, the `from_text` doc 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)."
It says "give the type of your symbol", and then gives an example `S -> "TER:John" "VAR:d" a b`.
It doesn't explicitly say if the head can be `"VAR:S"`.
In `_read_line`:
```python
if is_special_text(head_text):
head_text = head_text[5:-1]
head = Variable(head_text)
```
If `head_text` was `"VAR:S"`, `head_text` becomes `"S"`, and `head` becomes `Variable("S")`.
If `head_text` was `"TER:S"`, `head_text` becomes `"S"`, and `head` becomes `Variable("S")`.
But the head must be a Variable in CFG. So this seems okay.
Now let's implement the fix. I'll use `edit_file`.
Wait, I should check if I need to import `string` in `pyformlang/cfg/cfg.py`.
The current code uses `string.ascii_uppercase`. Let's check if `string` is imported.

Yes, it is.
Let's prepare the `edit_file` call.
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 \

body_ter = Terminal(body_component)

```
Wait, the original `elif` was:
```python

== "TER":
```
If `type_component == "TER"`, it would be a terminal.
If `body_component` was not in `EPSILON_SYMBOLS`, it would be a terminal.
But this was only reached if it didn't start with uppercase AND `type_component` was not `"VAR"`.
My proposed change:
```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)

This seems correct and covers all cases.
Let's apply the fix.Yes, it is.
Let's prepare the `edit_file` call.
Original code:

(type_component == "" and body_component not in EPSILON_SYMBOLS):
body_ter = Terminal(body_component)
terminals.add(body_ter)
body.append(body_ter)
```
Wait, the original `elif` was:
```python
elif body_component not in EPSILON_SYMBOLS or type_component \
== "TER":
```
If `type_component == "TER"`, it would be a terminal.
If `body_component` was not in `EPSILON_SYMBOLS`, it would be a terminal.
But this was only reached if it didn't start with uppercase AND `type_component` was not `"VAR"`.
My proposed change:
```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)
```
This seems correct and covers all cases.
