A transformer is a -function which is invoked each time a file is passed through the transform -phase. If an error occurs (either because it’s thrown, returned, rejected, or -passed to [`next`][next]), the process stops. - -The transformation process in **unified** is handled by [`trough`][trough], see -it’s documentation for the exact semantics of transformers. - -###### Parameters - -* `node` ([`Node`][node]) -* `file` ([`VFile`][file]) -* `next` ([`Function`][next], optional) - -###### Returns - -* `Error` — Can be returned to stop the process -* [`Node`][node] — Can be returned and results in further transformations - and `stringify`s to be performed on the new tree -* `Promise` — If a promise is returned, the function is asynchronous, and - **must** be resolved (optionally with a [`Node`][node]) or rejected - (optionally with an `Error`) - -#### `function next(err[, tree[, file]])` - -If the signature of a transformer includes `next` (third argument), the -function **may** finish asynchronous, and **must** invoke `next()`. - -###### Parameters - -* `err` (`Error`, optional) — Stop the process -* `node` ([`Node`][node], optional) — New syntax tree -* `file` ([`VFile`][file], optional) — New virtual file - -## `Preset` - -Presets provide a potentially sharable way to configure processors.

-###### Parameters - -* `node` ([`Node`][node]) — Found node -* `ancestors` (`Array.`) — [Ancestor][]s of `node` - -##### Returns - -The return value can have the following forms: - -* [`index`][index] (`number`) — Treated as a tuple of `[CONTINUE, index]` -* `action` (`*`) — Treated as a tuple of `[action]` -* `tuple` (`Array.<*>`) — List with one or two values, the first an `action`, - the second and `index`. - Note that passing a tuple only makes sense if the `action` is `SKIP`. - If the `action` is `EXIT`, that action can be returned. - If the `action` is `CONTINUE`, `index` can be returned. - -###### `action` - -An action can have the following values: - -* `visit.EXIT` (`false`) — Stop traversing immediately -* `visit.CONTINUE` (`true`) — Continue traversing as normal (same behaviour - as not returning anything) -* `visit.SKIP` (`'skip'`) — Do not traverse this node’s children; continue - with the specified index - -###### `index` - -[`index`][index] (`number`) — Move to the sibling at `index` next (after `node` -itself is completely traversed). -Useful if mutating the tree, such as removing the node the visitor is currently -on, or any of its previous siblings (or next siblings, in case of `reverse`) -Results less than `0` or greater than or equal to `children.length` stop -traversing the parent -
