charm

Constructors for charm values: RFC 6902 JSON Patches over a target's argv (see docs/charms.md).

path

Return the JSON Pointer ("/N") of the first argv element equal to anchor - the index, auto-calculated, for hand-built move/copy/test ops.

Signature: charm\path(argv, anchor) → string · source

Returns: string

pathFunc

Return the JSON Pointer ("/N") of the first argv element for which fn(s) is truthy.

Signature: charm\pathFunc(argv, fn) → string · source

Returns: string

move

Move the first argv element equal to anchor to the JSON Pointer to ("/-" end, "/0" front, or charm.path(...)).

Signature: charm\move(argv, anchor, to) → Charm · source

Returns: map[string]any

moveFunc

copy

Copy the first argv element equal to anchor to the JSON Pointer to ("/-" end, "/0" front, or charm.path(...)).

Signature: charm\copy(argv, anchor, to) → Charm · source

Returns: map[string]any

copyFunc

Copy the first argv element for which fn(s) is truthy to the JSON Pointer to.

Signature: charm\copyFunc(argv, fn, to) → Charm · source

Returns: map[string]any

test

Guard: assert the first argv element equal to anchor is still at its position when the patch applies (else the run errors).

Signature: charm\test(argv, anchor) → Charm · source

Returns: map[string]any

testFunc

Guard: assert the first argv element for which fn(s) is truthy is still at its position when the patch applies.
