Fix: Command fails when symbol name contains trailing text after backticks

[Mhdd-24]

Problem Explanation:
In the code, the backticks around the symbol name are handled later, but splitting the string happens earlier (symbol_name.split(maxsplit=1)[0]), which results in the symbol name being truncated before backtick handling is done.

For example:

!d \collections.Counter some more textis treated ascollections.Counter and the text after the symbol is ignored. However, the goal is to parse the symbol correctly even with extra trailing text after the backticks.

Solution:
To fix this issue, we should handle the backticks earlier, before splitting the symbol name, so that any extraneous text outside the backticks doesn't interfere with the symbol name.

Corrected Code:
You need to modify the get_symbol_item method to handle backticks properly before splitting. Here's the change:

python
Copy
Edit
def get_symbol_item(self, symbol_name: str) -> tuple[str, DocItem | None]:
"""
Get the DocItem and the symbol name used to fetch it from the doc_symbols dict.

If the doc item is not found directly from the passed in name and the name contains a space,
the first word of the name will be attempted to be used to get the item.
"""
# Remove backticks first
symbol_name = symbol_name.strip("`")

# Now, attempt to find the symbol item
doc_item = self.doc_symbols.get(symbol_name)
if doc_item is None and " " in symbol_name:
    symbol_name = symbol_name.split(maxsplit=1)[0]
    doc_item = self.doc_symbols.get(symbol_name)

return symbol_name, doc_item

Explanation of Fix:
Strip Backticks First: The symbol_name.strip("")` is added before anything else to remove any backticks around the symbol name.

Handle Extra Text: After backticks are stripped, the code can then handle any extra text properly, ensuring that the symbol name remains intact before splitting.

Result:
This will allow the command !d \collections.Counter some more text to work correctly by:

Stripping the backticks first.

Splitting the symbol name (collections.Counter) from any extra text only if needed.
