PGN import fails if line break after White move #10816

Closed dlbbld closed 2 years ago

dlbbld commented 2 years ago

When the black move is on a new line, the PGN import stops just before this move (Analysis Board and Import Game feature):

1.e4
c5

Results in 1.e4.

1.e4 c5 2.Nf3
Nc6

Results in 1.e4 c5 2.Nf3.

1.e4 c5 2.Nf3 Nc6 3.d4
cxd4

Results in 1.e4 c5 2.Nf3 Nc6 3.d4.

When will the fix be deployed?

Thanks, that works now. Fast fix!

On board is fine but For Tools / Import game, first, I think it did not work because it saves the imports, so it still showed the wrong results from yesterday. So I needed to delete yesterday's import first. That's quite a pitfall.

On top of it, if somebody else has already imported the PGN, I cannot delete it to correctly import. That questions a bit the usefulness of saving the import. Better would be already to compare the result of the import with the saved import and when the result is different, create a new import, to avoid such problems (created #10818).

For example, importing the below in Tools / Import game:

1.e4 c5 2.Nf3 Nc6 3.d4
cxd4

still results in 1.e4 c5 2.Nf3 Nc6 3.d4 as I still have one old import from yesterday (https://lichess.org/CxeYSWGr).

Only when amending the PGN by adding some tags for example, so it creates a new import entry, the result is correct

[Site "Some random string"]
1.e4 c5 2.Nf3 Nc6 3.d4
cxd4

Results correctly in 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4
