[feat] code completion for wiki links to headline

[ray-x]

e.g. [[another-notes#_]] when cursor on _, it should list all headlines in another-notes, bellow is marksman behavior

While oxide treats # inside a wiki link as tag, so the result is a bit confusing

I'm sorry that you are experiencing this! It shouldn't happen, however. Make sure that you have nvim-cmp configured properly, as this would cause the issue. Also make sure you have the latest version

{
name = 'nvim_lsp',
  option = {
    markdown_oxide = {
      keyword_pattern = [[\(\k\| \|\/\|#\)\+]]
    }
  }
},

Thanks, after updating the nvim-cmp setup. It works now.

Just wondering why extra config is necessary in this case. But I am happy to close the issue.

(Wierdly) Unlike other completion engines (VSCode, Zed, ...), nvim-cmp will end a completion after you type a space. I think it assumes that only keywords (variable names, constants, ...) will be completed, and so any characters that are not typical of a keyword will cause completions to end. One of these characters is # and another is space . Others relevant to this are in that keyword_pattern.

It is very odd behavior and is made even worse by having to use a vim pattern (which is not very intuitive to me). The creator of Obsidian.nvim had a similar struggle, which he helped me with a few months ago. Also, be on the lookout for an RFC proposing markdown-oxide as a backend for Obsidian.nvim -- offloading performance-intensive tasks like completions etc. I have been in contact with the creator recently, and he gave me the go-ahead to make the proposal!

In addition to this, nvim-cmp has odd behavior with tags for some reason #17 . I really think that it is a bottleneck for neovim LSP ecosystem (and beyond) and it deserves a rewrite.

Just some thoughts!

I think this is a setup on the lsp side. The specification has this:

/**
 * How a completion was triggered
 */
export namespace [CompletionTriggerKind](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#completionTriggerKind) {
    /**
     * Completion was triggered by typing an identifier (24x7 code
     * complete), manual invocation (e.g Ctrl+Space) or via API.
     */
    export const Invoked: 1 = 1;

    /**
     * Completion was triggered by a trigger character specified by
     * the `triggerCharacters` properties of the
     * `CompletionRegistrationOptions`.
     */
    export const TriggerCharacter: 2 = 2;

    /**
     * Completion was re-triggered as the current completion list is incomplete.
     */
    export const TriggerForIncompleteCompletions: 3 = 3;
}
export type [CompletionTriggerKind](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#completionTriggerKind) = 1 | 2 | 3;
