Having a hard time to understand why this parser doesn't work

[beeb]

I am making a parser for a type of doc-comments in the Solidity language.

At the core of it, I'm parsing a line of text which ends with a newline.

See the following examples:

@title The Title\n

@dev Hello World\n

  @param foo A param\n

 * @return something\n

\t**@author\n

hello world\r\n

  foo bar\n

 * Something\n

 * Something */

\n

* \n

So the line can start with nothing, whitespace, whitespace followed by one or more stars. Followed by optional whitespace and then either a keyword followed by some text (@title, @param, etc, some of them have a required identifier after), or simply some text (also optional). Until a newline or end of comment */.

I made two functions, one for the keyword case, and one for the non-keyword case (which is the same as using @notice), that I plan to use in alt(). Neither of them work for their respective inputs.

Can you spot a mistake in what I wrote?

I think the problem might come from the fact that I don't consume the line ending or */ at the end? But I would like to not consume it because those parsers will then by used in a separated(_, line_ending).

Ok it seems that if I don't use that parser in isolation but combine it with separated or simply append a line_ending combinator after, everything works as expected!
