<!-- if this PR closes one or more issues, you can automatically link the PR with them by using one of the [*linking keywords*](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword), e.g. - this PR should close #xxxx - fixes #xxxx you can also mention related issues, PRs or discussions! --> # Description - fixes: #5517 - fixes: #9250 For the following commands: ``` ls # | le | length ``` I found that it generates a bad lite parsing result: ``` LiteBlock { block: [ LitePipeline { commands: [ Command(None, LiteCommand { comments: [], parts: [Span { start: 138600, end: 138602 }] }) ] }, LitePipeline { commands: [ Command(Some(Span { start: 138610, end: 138611 }), LiteCommand { comments: [Span { start: 138603, end: 138609 }], parts: [Span { start: 138612, end: 138618 }] }) ] } ] } ``` Which should contains only one `LitePipeline`, and the second `LitePipeline` is generated because of `Eol` lex token: ``` [ Token { contents: Item, span: Span { start: 138600, end: 138602 } }, Token { contents: Eol, span: Span { start: 138602, end: 138603 } }, // it generates the second LitePipeline Token { contents: Comment, span: Span { start: 138603, end: 138609 } }, Token { contents: Pipe, span: Span { start: 138610, end: 138611 } }, Token { contents: Item, span: Span { start: 138612, end: 138618 } } ] ``` To fix the issue, I remove the `Eol` token when we meet `Comment` right after `Eol`, then it will generate a good LiteBlock, and everything will work fine. ### After the fix: Token: ``` [ Token { contents: Item, span: Span { start: 138618, end: 138620 } }, Token { contents: Comment, span: Span { start: 138622, end: 138628 } }, Token { contents: Pipe, span: Span { start: 138629, end: 138630 } }, Token { contents: Item, span: Span { start: 138631, end: 138637 } } ] ``` LiteBlock: ``` LiteBlock { block: [ LitePipeline { commands: [ Command( None, LiteCommand { comments: [Span { start: 138622, end: 138628 }], parts: [Span { start: 138618, end: 138620 }] } ), Command( Some(Span { start: 138629, end: 138630 }), LiteCommand { comments: [], parts: [Span { start: 138631, end: 138637 }] })] }] } ``` <!-- Thank you for improving Nushell.
