How to process the last line without line feed

[kkayal]

I have tried the CSV Example in the documentation. I have used the online editor.

The grammar definition is

field = { (ASCII_DIGIT | "." | "-")+ }
record = { field ~ ("," ~ field)* }
file = { SOI ~ (record ~ ("\r\n" | "\n"))* ~ EOI }

and the input is

65279,1179403647,1463895090
3.1415927,2.7182817,1.618034
-40,-273.15
13,42
65537

Note that there is a single line feed character at the end of this input, which looks like an empty line here.

The parser works as documented. Now, when I remove the last line feed character at the end of the file, which is often the case in real world input files, the parser throws the following error:

 --> 5:1
  |
5 | 65537
  | ^---
  |
  = expected EOI

I have tried to remove the EOI from these 3 lines of grammar definition. Then, I get no more error messages, but then, the output lacks the last line with the value 65537:

- file
  - record
    - field: "65279"
    - field: "1179403647"
    - field: "1463895090"
  - record
    - field: "3.1415927"
    - field: "2.7182817"
    - field: "1.618034"
  - record
    - field: "-40"
    - field: "-273.15"
  - record
    - field: "13"
    - field: "42"

So the parser seems to stop at the very last line feed character as the EOI, although there is more valid input. Is this a bug or a feature?

If it is a feature, how do I have to modify the grammar so that I also get the 65537 in the output?

Thanks!
