[ruby-core:120072] [Ruby master Bug#20918] Prism error indicates line number of `-e` that does not exist

1 Dec 2024

      Issue #20918 has been updated by ydah (Yudai Takada).

It seems that the `foo {` has the same problem.

````
❯ ruby -e 'foo {'
-e: -e:2: syntax errors found (SyntaxError)
...
1 | foo {
    | ^ expected a block beginning with `{` to end with `}`
2 |
    | ^ unexpected end-of-input, assuming it is closing the parent top level context

Since the error is not confirmed until EOL, it looks like you are outputting the position where the error is confirmed.

❯ ruby -e "foo(

"
-e: -e:4: syntax error found (SyntaxError)
  2 |
  3 |
...
4 |
    | ^ unexpected end-of-input; expected a `)` to close the arguments

$ ruby -e 'foo('
-e: -e:2: syntax error found (SyntaxError)
  1 | foo(
...
2 |
    | ^ unexpected end-of-input; expected a `)` to close the arguments

It says `-e:2`, but there is no line 2 in `-e 'foo('`.

`eval("foo(")` reports line 1, so I guess this issue is only for `-e`.
