generate completions from tree-shaped data

[fj0r]

it might be too trivial to manually create a completion. in many scenarios, completion is a tree-shaped structure - the current candidate is influenced by the previous candidate.

completion-generator generate completion through tree-like structures

def test [...args:string@com-test] {}

def com-test [...context] {
    $context | completion-generator from tree {
        a: {
            b: {
                c: {
                    d: 1
                    e: 2
                }
            }
            f: [g h i]
        }
        j: {|path| [k l m]}
        n: [
            {value: o, description: .., next: [p q]}
            {value: r, description: .., next: {s: t, u: v, w: x}}
        ]
    }
}

it uses existing positional arguments as a breadcrumbs to select candidates in tree structures

as an example, completion-generator flare to create completion from online json data

completion-generator supports different structural expressions

{value: desc}
{value: { next : ...}
[a b c ...]
[{value: a, description: b, next: [...]]
{|path| ...}

these different structures allow any kind of nesting
